What's Up UA? - Happy 90th Birthday, Steward Observatory

"We have the best location of any educational institution in America. The University ought to make itself famous with a telescope."

With those words, part of his long and persistent effort to bring a world-class observatory to the University of Arizona campus, pioneering astronomer Andrew Ellicott Douglass set forth his best argument.

Arriving at the UA in 1906 from the Lowell Observatory outside Flagstaff, Douglass sought almost immediately to take advantage of Tucson's dry climate and clear night skies, using his renowned 1910 Halley's Comet observations as proof of the region's unique potential. As he wrote in a 1908 guest editorial in the Arizona Daily Star, "Nothing advertises a climate better than a big telescope."

The paper's editors agreed: "The fame of its observatory would be greater than any other institution of like character in the United States. The atmospheric conditions are such as to demand recognition and consideration from the scientific men of all nations," according to a Feb. 6, 1910 editorial.

Douglass unsuccessfully lobbied the state Legislature for funds but in 1916 secured a $60,000 donation, at first anonymously from Oracle resident Lavinia Steward, in memory of her late husband Henry B. Steward. Construction on Steward Observatory began that year, and on April 23, 1923, the UA formally dedicated the facility, with its state-of-the art 36-inch reflecting telescope at last making Tucson an astronomer's paradise.

"Not only was this the first big donation (to the UA), it was the start of research at the University in a very real way," says Buell Jannuzi, current director of Steward Observatory and head of the astronomy department.

From those ambitious beginnings – the Steward telescope was nicknamed the "All-American" because it was the first astronomical telescope built using all American-made products – the observatory and astronomy department have branched out in all directions, to radio, X-ray and ultraviolet astronomy, adaptive optics, space-based telescopes and the renowned Steward Observatory Mirror Laboratory, which constructs gigantic mirrors for the next generation of astronomy, the Large Synoptic Survey Telescope and the Giant Magellan Telescope.

"Douglass wanted more than just a major telescope for the University of Arizona; he wanted Steward Observatory to produce discoveries and to share them with the world. I think he would agree that his successors have continued to develop the quality of research we're producing, using technological innovations not as the end points, but as tools to further scientific discovery," Jannuzi says. "Our aspirations are the same as those of Douglass; we are just pursuing them with more modern tools."

Built on what was then the far east side of Tucson, Steward Observatory has been overtaken by campus expansion yet remains an iconic fixture of the UA, its white brick and dome now housing the 21-inch Raymond E. White Jr. Reflector telescope, used primarily for undergraduate education and public outreach, which has been a part of the observatory's mission since its dedication. The original 36-inch scope relocated to Kitt Peak in 1963 and remains in use by the Spacewatch Project.

Leadership for Steward Observatory has maintained a remarkable continuity, with just seven directors over its 90 years, including Peter A. Strittmatter, who served 37 years as director and led a remarkable period of growth and development.

"I think (Douglass) would agree the soul is still there in the observatory, and we're continuing the mission he set out for us," Jannuzi says, reflecting on what drew him to astronomy in the first place. "It's fun, like philosophers or theologians do, to think about the big questions. Often times we're working on some small part of a research project, but it's all part of a larger effort to understand the universe and how we relate to it."

What's Up UA? - Supernova Discovered at UA SkyCenter

Now you see it – now you don't. This, in a nutshell, describes how Adam Block, renowned astrophotographer and astronomy educator with the University of Arizona's Mt. Lemmon SkyCenter, discovered a supernova in a galaxy far, far away.

 
Block was looking at a photograph he had taken with the Schulman Telescope at the SkyCenter in April, showing a galaxy located about 400 million light years away, when a tiny blip in the image caught his eye. Indistinguishable from the many other stars visible in the image, Block realized this one was different when he put his photo next to one taken by the Hubble Space Telescope.
 
"I noticed that there was this star in my picture that wasn't there in the Hubble image," Block said. "That got me excited, and I thought, 'You know what, that looks just like a supernova. That's what they look like.'"
 
Not all stars end their lives in an explosion of cosmic proportions. Our sun, for example, is too small to go supernova. Once it has exhausted its hydrogen fuel, it will shed much of its mass and end its life as a white dwarf, slowly cooling and eventually fading out.
 
The kind of supernova Block detected in his image of galaxy NGC 6240 is caused by a single star that blew up at the end of its relatively short life.
 
"The star had to be at least 10 or more times the mass of our sun," Block explained. "When it explodes, it hurls its material out in a giant bubble that expands and dissipates into the surrounding space. The gas from this explosion is so fast it would race past the Earth in a few seconds."
 
Block said supernovae typically remain visible only for a few months, growing dimmer over time before they disappear.
 
He said although extragalactic supernovae are not particularly rare events, he considers himself very lucky. 
 
"They're not terribly unusual," he said. "If you could look at 1,000 galaxies every night, you would witness one supernova on average."
 
Astronomers find small numbers of them every week, but they use specialized observation software that systematically looks for supernovae, Block said.
 
"To find one randomly is like winning the supernova lottery. I wasn't looking for a supernova specifically; I was just comparing the images. I do it all by eye. I have been wanting to find a supernova for a long time. To many people, a blip like this wouldn't stand out, but to me, it does."
 
Block said he owes his supernova lottery ticket to data he had collected for an astronomy workshop in April, which ended up not being used.
 
"A month after the workshop, I went back to those data and decided to process them and make one of the pretty images as I normally do. When I'm working on faint, deep space objects like this galaxy, I often compare them to existing images of the same object. There weren't many of this object in high resolution, except for that Hubble image."
 
"NGC 6240 is a famous object," Block said. "It looks like a mess because it's the result of two galaxies colliding. If you look closely, you see two bright spots in the center. Those are the two galactic centers, each of which containing massive black holes, which will eventually merge into one."
 
The location in which Block first spotted the suspicious "star" turned out to be indicative of a supernova, too, as it is in a region where many stars are being born.
 
"What happens in a star-forming region is you have a place where massive stars form, and those have short lives. The really big ones last only a few handful of millions of years, and they die in the same region where they were born."
 
Once Block thought he had found something interesting, he had to make sure it wasn't something that was already known. He turned to the Central Bureau of Astronomical Telegrams, or CBAT, an organization founded in 1880 in Germany and moved to Harvard University in 1965. CBAT keeps a record of discoveries of asteroids, comets, variable stars, planets and supernovae.
 
Block searched the database for a list of all supernovae that had been discovered in the past three to four months.
 
"Supernovae like this one remain bright only for a handful of months, and there was nothing reported for galaxy NGC 6240."
 
Block submitted a report to CBAT, the first step in confirming the new object. To rule out an alternative explanation, such as a variable star appearing in the foreground, an analysis of its spectrum was needed, something Block could not do with the Schulman Telescope. A spectrum can be thought of as a fingerprint of light that reveals clues about composition, temperature and other characteristics of a star or similar object.
 
"For the final confirmation, someone has to analyze the spectrum and compare it to several models," Block explained. "If it fits, you know it is indeed a supernova."
 
The blip Block had discovered fit perfectly and was officially designated as supernova SN2013DC on June 9.
 
"That's is the cool thing," Block said. "In those moments, I realize I may be the only person in the world who knows about this supernova. It's a powerful way to connect with the universe. People used to think that the cosmos was immutable; the heavens were believed to never change. Witnessing the universe change on the short timescales humans can appreciate is amazing."

What's Up UA? - Marks on Martian Dunes May Reveal Tracks of Dry-Ice Sleds
NASA research indicates that hunks of frozen carbon dioxide – or dry ice – may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.
 
Researchers deduced this process could explain one enigmatic class of gullies seen on Martian sand dunes by examining images from NASA's Mars Reconnaissance Orbiter, or MRO, and performing experiments on sand dunes in Utah and California.
 
"I have always dreamed of going to Mars," said Serina Diniega, a planetary scientist at NASA's Jet Propulsion Laboratory, or JPL, in Pasadena, Calif., and lead author of a report published online by the journal Icarus. "Now I dream of snowboarding down a Martian sand dune on a block of dry ice."
 
The hillside grooves on Mars, called linear gullies, show relatively constant width – up to a few yards or meters across – with raised banks or levees along the sides. Unlike gullies caused by water flows on Earth and possibly on Mars, they do not have aprons of debris at the downhill end of the gully. Instead, many have pits at the downhill end.
 
"In debris flows, you have water carrying sediment downhill, and the material eroded from the top is carried to the bottom and deposited as a fan-shaped apron," said Diniega. "In the linear gullies, you're not transporting material. You're carving out a groove, pushing material to the sides."
 
Images from MRO's High Resolution Imaging Science Experiment, or HiRISE, camera, operated by the University of Arizona, show sand dunes with linear gullies covered by carbon dioxide frost during the Martian winter. The location of the linear gullies is on dunes that spend the Martian winter covered by carbon dioxide frost. The grooves are formed during early spring, researchers determined by comparing before-and-after images from different seasons. Some images have even caught bright objects in the gullies.
 
Scientists theorize the bright objects are pieces of dry ice that have broken away from points higher on the slope. According to the new hypothesis, the pits could result from the blocks of dry ice completely sublimating away into carbon-dioxide gas after they have stopped traveling.
 
"Linear gullies don't look like gullies on Earth or other gullies on Mars, and this process wouldn't happen on Earth," said Diniega. "You don't get blocks of dry ice on Earth unless you go buy them."
 
That is exactly what report co-author Candice Hansen, of the Planetary Science Institute in Tucson, Ariz., did. Hansen has studied other effects of seasonal carbon-dioxide ice on Mars, such as spider-shaped features that result from explosive release of carbon-dioxide gas trapped beneath a sheet of dry ice as the underside of the sheet thaws in spring. She suspected a role for dry ice in forming linear gullies, so she bought some slabs of dry ice at a supermarket and slid them down sand dunes.
 
That day and in several later experiments, gaseous carbon dioxide from the thawing ice maintained a lubricating layer under the slab and also pushed sand aside into small levees as the slabs glided down even low-angle slopes.
 
The outdoor tests did not simulate Martian temperature and pressure, but calculations indicate the dry ice would act similarly in early Martian spring where the linear gullies form. Although water ice, too, can sublimate directly to gas under some Martian conditions, it would stay frozen at the temperatures at which these gullies form, the researchers calculate.
 
"We have seen blocks of ice sitting in the channels in our HiRISE images," said Alfred McEwen, a professor of planetary science at the UA who leads the HiRISE program who co-authored the paper. "Later, we saw them disappear by sublimation, in a matter of months."
 
Although the HiRISE camera doesn't allow researchers to measure the blocks' composition directly, McEwen said they behaved in the right way for carbon dioxide ice.
 
"Water ice block should be stable for much longer periods of time, and we know there is ample carbon dioxide in the area where those gullies are seen – in the higher latitudes of Mars' southern hemisphere."
 
"The origin of these linear gullies has been a mystery," McEwen added. "This study provides some direct clues as to how they are forming. The experiments using the dry ice show that our hypothesis is plausible."
 
Hansen also noted the process could be unique to the linear gullies described on Martian sand dunes.
 
"There are a variety of different types of features on Mars that sometimes get lumped together as 'gullies,' but they are formed by different processes," she said. "Just because this dry-ice hypothesis looks like a good explanation for one type doesn't mean it applies to others."
 
McEwen said the study adds an exciting new piece to growing series of discoveries about ongoing, active processes shaping the surface of the Red Planet. 
 
"We are finding Mars is not Earth-like as it looks," he said. "Dry ice doesn't naturally exist here on Earth. MRO and the HiRISE instrument are healthy, and the longer the mission goes on, the longer we can observe and really understand these processes over the long term."
 
McEwen said the team is planning to continue to monitor these sites to see more ice blocks in action.
 
"We can't get any information from other instruments on the orbiter, because the features are too small," he explained. "But we are learning more about the distribution and latitude of those features and when they are active."
 
The UA's Lunar and Planetary Laboratory operates the HiRISE camera, which was built by Ball Aerospace & Technologies Corp. of Boulder, Colo. JPL manages MRO for NASA's Science Mission Directorate in Washington. Lockheed Martin Space Systems of Denver built the orbiter.

What's Up UA? - Astronomers Gear Up to Discover Earth-Like Planets
If one looks only for the shiniest pennies in the fountain, chances are one misses most of the coins because they shimmer less brightly. This, in a nutshell, is the conundrum astronomers face when searching for Earth-like planets outside our solar system.
 
Astronomers at the University of Arizona are part of an international team of exoplanets hunters developing new technology that would dramatically improve the odds of discovering planets with conditions suitable for life – such as having liquid water on the surface.
 
The team presented its results at a scientific conference sponsored by the International Astronomical Union in Victoria, British Columbia.
 
Terrestrial planets orbiting nearby stars often are concealed by vast clouds of dust enveloping the star and its system of planets. Our solar system, too, has a dust cloud, which consists mostly of debris left behind by clashing asteroids and exhaust spewing out of comets when they pass by the sun.
 
"Current technology allows us to detect only the brightest clouds, those that are a few thousand times brighter than the one in our solar system," said Denis Defrère, a postdoctoral fellow in the UA'sdepartment of astronomy and instrument scientist of the Large Binocular Telescope Interferometer, or LBTI.
 
He explained that while the brighter clouds are easier to see, their intense glare makes detecting putative Earth-like planets difficult, if not impossible. "We want to be able to detect fainter dust clouds, which would dramatically increase our chances of finding more of these planets."
 
"If you see a dust cloud around a star, that's an indication of rocky debris, and it increases the likelihood of there being something Earth-like around that star," said Phil Hinz, an associate professor of astronomy at the UA's Steward Observatory. 
 
"From previous observations, we know that these planets are fairly common," he added. "We can expect that if a space telescope dedicated to that mission were to look around a certain area of sky, we'd expect to find quite a few."
 
Hinz and Defrère are working on an instrument that will allow astronomers to detect fainter clouds that are only about 10 times – instead of several thousand times – brighter than the one in our solar system. 
 
"It's like being here in Victoria and trying to image a firefly circling a lighthouse in San Francisco that is shrouded in fog," Defrère said about the technological challenge. 
 
"That level of sensitivity is the minimum we need for future space telescope missions that are to characterize Earth-like planets that can sustain liquid water on the surface," he explained. "Our goal is to eliminate the dust clouds that are too bright from the catalog of candidates because they are not promising targets to detect planets suitable for life."
 
"With a bright dust cloud, which is 1,000 times brighter than the one in our solar system, its light becomes comparable to that of its star, which makes it easier to detect," explained Hinz. 
 
Fainter clouds, on the other hand, can be about 10,000 times less bright than their star, so it becomes difficult or impossible for observers to make out their faint glow in the star's overpowering glare. 
 
Funded by NASA, the team is in the middle of carrying out tests to demonstrate the feasibility of these observations using both apertures of the Large Binocular Telescope, or LBT, in Arizona. The project aims at determining how difficult it would be to achieve the desired results before committing to a billion-dollar space telescope mission. 
 
According to Hinz, NASA's goal is to be able take a direct picture of Earth-like, rocky planets and record their spectrum of light to analyze their composition and characteristics such as temperature, presence of water and other parameters.
 
"To do that, one would need a space telescope specifically designed for this type of imaging," he said. "Our goal is to do a feasibility study of whether it would be possible to distinguish the light emission of the planet from the background emission of the dust cloud through direct observation."
 
The researchers take advantage of a technique known as nulling interferometry and the unique configuration of the LBT, which resembles a giant pair of binoculars. 
 
"We combine the light from two apertures, cancel out the light from the central star, and with that it becomes easier to see the light from the dust cloud," Hinz explained. "To achieve this, we have to cause the two light paths to interfere with each other, which requires lining them up with very high precision. We'll always have some starlight left because of imperfections in the system, but our goal is to cancel it out to a level of 10,000 to get down to where we can at least detect the faint glow of the dust cloud."
 
The work presented at the conference used the same technique with the two large telescopes of theKeck Observatory in Hawaii in order to detect the dust cloud around the star Fomalhaut located 25 light years from our sun. 
 
"Based on our observations at the European Very Large Telescope Interferometer, we knew that Fomalhaut was surrounded by a bright dust cloud located very close to the star," said Jérémy Lebreton, principal investigator of the study, who is at the Institut de Planétologie et d'Astrophysique in Grenoble, France. 
 
"Using the Keck Interferometer, we found out that Fomalhaut has a less bright, more diffuse cloud orbiting close to the habitable zone that resembles the Main Asteroid Belt in our solar system. This belt is likely in dynamical interaction with yet undetected planets."
 
The study presented here is one in a series of three publications and was conducted in collaboration with the University of Amsterdam; the University of Liège in Belgium; NASA’s Jet Propulsion Laboratory at Caltech, Pasadena, Calif.; the University of Paris; and the University of Arizona in Tucson, Ariz. 
 
Approximately 250 scientists from around the world convened at the scientific conference, Exploring the Formation and Evolution of Planetary Systems, held June 3-7 in Victoria to discuss the latest observations and theories about exoplanetary systems.

What's Up UA? - Brigetta Barrett Named Pac-12 Woman of the Year

The University of Arizona's Olympic silver medalist high jumper Brigetta Barrett has been named the Pac-12 Conference Woman of the Year for the 2012-13 academic year, Pac-12 Commissioner Larry Scott has announced.

Watch this mini-documentary to learn more about Barrett's will to rise, leading up to her silver medal performance at the 2012 Olympics in London.

 

Barrett becomes the conference's candidate for the NCAA Woman of the Year, presented annually to graduating student-athletes who have distinguished themselves throughout their collegiate careers in the areas of academic achievement, athletics excellence, community service and leadership.

Barrett was a silver medalist at the 2012 Olympic Games in London in the high jump, where she recorded the best mark ever by a collegian with a height of 2.03m/6-7. A three-time Pac-12 champion in the event, she set the NCAA record in a collegiate meet at the Pac-12 Championships in May, jumping a height of 1.99m/6-6.25.

Barrett has won three NCAA indoor high jump titles and two in the outdoor event. She will be going for a third national title in the outdoor this week at the NCAA Championships in Eugene, Ore.

Additionally, Barrett was named a Bowerman finalist in 2012 and is on the watch list again this season. The honor is given annually to the most outstanding men's and women's collegian in the sport of track and field.

Barrett has also excelled in the classroom, graduating cum laude in May, earning a bachelor's degree in theater arts. In 2011, she was voted a Capital One Academic All-America by the College Sports Information Directors of America and earned a spot on UA's Dean's List in the fall of 2009. She has also been honorable mention Dean's List five times during her academic career.

Barrett has served in several leadership positions, including being selected the co-president of the Pac-12 Student-Athlete Advisory Committee and was a team captain on the Wildcat track and field squad. She is also currently the co-president of the Committed to Christ student group on campus.

Voted UA's Homecoming Queen this year, she continues to participate in several community service efforts, including Mentor Kids USA, a program that encourages young girls to pursue education and self-respect; Susan G. Komen, with a specific focus on helping to promote and facilitate race-day coordination; and Students on Stage, where she mentors fellow students and helps create an environment where they can express themselves and achieve common artistic goals.

Looking to eventually pursue a career in the performing arts, Barrett has been invited to sing the National Anthem at numerous sporting events, including the 2012 Pac-12 Men's and Women's Track and Field Championships, a Diamondbacks baseball game, the Fiesta Bowl and Arizona football games. She has also sung the National Anthem at the Susan G. Komen Breast Cancer Walk, the State of the City address where she was invited by the mayor of Tucson, and at different high schools where she also has talked about the importance of academic success.

Barrett is the eighth student-athlete to be named Pac-12 Woman of the Year. Previous winners were: Hilary Back, ASU (2012); Annie Chandler, UA (2011); Justine Schluntz, UA (2010); Lacey Nymeyer, UA (2009); Arianna Lambie, Stanford (2008); Whitney Myers, UA (2007); Kate Richardson, UCLA (2006). Barrett is the fifth Wildcat to earn the honor. Four from the Conference have won the prestigious NCAA Woman of the Year honor.

The top 30 honorees, 10 from each NCAA division, will be announced in early September. The NCAA Woman of the Year is announced in October.

What's Up UA? - UA Classical Guitar Program Among World’s Best

Chilean Master's student Pablo Gonzalez first picked up a classical guitar when he was 8 years old. The Spanish guitar stayed with him through his early education and finally swept him north to the University of Arizona as a Fulbright scholar, where he joined the roughly 25 undergraduate and graduate students in the UA's Bolton Guitar Studies Program.

"You can find it in almost any home in my country," Gonzalez said of classical guitar music.

Students in the UA program hail from countries around the world, including France, Chile, Philippines, China, Brazil, Peru, Mexico, Argentina, Norway, Turkey and many others, drawn by the reputation of a music program like no other.

Many elements of the Bolton guitar program are found in no other classical guitar program in the world such as four endowed guitar competitions supported by the D'Addario string company and by donors, said professorR. Thomas Patterson, who heads the program.

With boons such as artists in residence David Russell, a world-renowned musician and recording artist, and Grammy Award winners Sérgio and Odair Assad, it may not be surprising that UA classical guitar students regularly win at national and international guitar competitions.

"The Assad Brothers come for a week in the fall, and David Russell comes for a week in the spring, and they teach for a week and give concerts," said Julia Pernet, chairman of the Tucson Guitar Society. "I think that's a very unusual asset to have, to have that class of performing guitarists come and spend a week, and really know the students."

Patterson, who joined the UA faculty in 1980, is credited by many for making the guitar program what it is today. "I wanted to make it a flagship, a model for other programs around the country, around the world," Patterson said.

"If you ask other guitar professors what are their greatest achievements, they say, 'Well, I published this book, or that book,'" said Misael Barraza, a first year Master's student in the program, who recently won theMontreal International Competition. "If you ask Tom, he'll say, 'See this guitar champion, or that champion? This was my student.'"

"One of the great things that Tom is able to do is assist students to get to these international competitions and to try themselves out against the world," Pernet added.

"We've seen people make extraordinary moves within our program," said Patterson. "It's exciting to see a high-end person achieve an international prize, but someone who maybe you're taking a risk with, to see them succeed is absolutely amazing."

Pernet brings world-renowned performing artists to Tucson every year through the Tucson Guitar Society. "Part of the agreement that I sign with them is that they will give master classes for the UA guitar program," she said.

In 2011, Sanford and Phyllis Bolton, lifelong music lovers and supporters of classical guitar, gave $2 million to establish the Sanford and Phyllis Bolton Endowed Chair for Classical Guitar, a position held by professor Patterson. Shortly after, Bolton gave an additional $1.1 million, establishing the Sanford and Phyllis Bolton Endowment for Guitar. 

"This was the largest gift of its kind in the history of fine arts," Patterson said, a gift that has enabled the program to support talented students who otherwise may not be able to pursue their dreams with acoustic guitar. In honor of the support, the program changed its name to the Bolton Guitar Studies Program.

The reputation of the program, its calendar packed with events and activities, and the supportive student community have attracted classical guitar talents from many nations. "I'm here because of the reputation of the guitar program," said Ivar Fojas, who is from the Philippines and also a Fulbright scholar, entering the third year of his doctoral studies.

"Normally, other guitar programs would have one or two recitals each semester," Fojas said. "We have them every single week. I've learned how to listen, to really be critical of myself."

"That's really what makes the difference between players," Barraza added. "Is how well you can listen to yourself."

The guitar program curriculum engages students in the community, with a public performance every Friday at 11 a.m. in the UA Museum of Art, and many other concerts and recitals throughout the year.

Patterson said he also makes effort to engage the community through concerts and working with children, to get them involved with guitar and music at a young age.

"It really pushes you to have higher standards for yourself," said Leandra Hubka, who is finishing her Master's degree. "There are so many opportunities to play for the public," she added. "You get better by playing for people."

Barraza said he aims for a concert career, and that the UA guitar program has "been a huge influence on me. I wouldn't be able to do without it."

"We have an enormously supportive group of people," Patterson said. "I have friends who have traveled all over the world; I ask them if this happens anywhere else, and they say no."

"We have four in-house competitions each year," Hubka said. "It would be really easy to get competitive with each other, but we're not at all." Perhaps competition is out of the question among a group of people unified by the sound of an instrument they can't put down.

"It has that effect sometimes," Barraza mused. "The guitar just grabs onto you, and that's it."

What's Up UA? - The New Face of Mining: Women Carving Out a Place in Surging Industry

They roam the remotest corners of the world, scale the highest mountains and descend deep into the Earth.

They go places few women have ever gone. They are not afraid of getting dirty, or of much else for that matter, certainly not adversity or a good challenge. And they know, better than most, how and when to take a joke.

"I went to the deepest, darkest corners of the Earth," said University of Arizona mining engineering alum Barb Filas, who has worked on every continent except Antarctica. "I hired local experts to help with environmental impact assessments for mining projects, drove around and looked at the landscape with the most competent of tour guides, and I was paid to do it."

For years, women have been carving out a place for themselves in an industry where their exclusion likely is as old as the profession itself – but where their inclusion today is critical to meeting a shortage of skilled workers.

The Society for Mining, Metallurgy, and Exploration estimates that before the end of the decade, the mining industry, where women now make up about 13 percent of the workforce, will need 128,000 skilled workers to replace retirees and fill new jobs, and more than half the workforce will be retired and replaced by 2029.

"There is a shortage of engineers in the industry right now," said recent UA graduate Bree McMaster, "and mining companies are trying to fill in the gaps and train up people fairly quickly so they can take on senior positions."

The UA department of mining and geological engineering, one of only 14 U.S. schools offering mining engineering degrees and only a handful with its own student mine, is dedicated to helping fill that pipeline, and that includes ensuring female engineers continue to gain ground in a surging industry.

"I worked on a research project several years ago to teach science, engineering and math to girls in Girl Scouts. When we started the program, we asked the girls to draw pictures of what they thought engineers looked like. They mostly drew pictures of men driving trains," said UA Distinguished Professor Mary Poulton, mining and geological engineering department head and director of the UA Lowell Institute for Mineral Resources.

"When we finished the program, they drew pictures of themselves. It is easier to imagine yourself doing a job if you see others who look like you doing the job."

Early UA Grad Paved Way Underground

Veteran Filas, who followed her father and grandfather into mining, was an anomaly when she graduated in 1978, and by most accounts, she was a rarity when she semi-retired in February 2013. Yet, in her 35-year climb from the underground coal mines of Illinois to the boardroom of a global mining firm, she has seen more change than she ever imagined.

"When I graduated, there were no women in front of me," said Filas. "There were a few women working in the mines, but none in engineering and certainly none at the corporate level."

Nowadays mining boots come in women's sizes, and most mine sites have women's change rooms. Technological advances are helping ease some of mining's brute-force image, and safety precautions have been greatly improved. Industry leaders understand that greater inclusion of women in mining jobs is imperative to sustaining the workforce, and they are committed to fostering a more gender-friendly work environment.

Female mining and geological engineers are involved in every stage of mining operations – from discovering mineral deposits and drilling for core samples; analyzing the ore and assessing mineral worth to managing equipment and people; setting explosives; and overseeing environmental impact, health and safety, mine design, and reclamation of mine sites.

"The mentality has changed a lot because the industry has changed a lot," said Filas. "But it's like trying to change anything; it takes generations to change a culture."

There still can be pockets of lingering intolerance associated with women in the industry, but that would be the case in any traditionally male industry, said Ruby Barickman, also a recent UA mining engineering graduate. Barickman spent a summer interning at a coal mine in Alabama and reported that some old-timers underground definitely did not think women should be in mines; in fact, they believed having women underground was bad luck.

"But by the end of the summer, once everyone knew me, they were a little more comfortable with the idea of a woman in the industry," said Barickman, adding that a sense of humor is vital in any new work environment.

"No matter who you are, anyone new on the job has to have thick skin," she said. "You have to be able to laugh at yourself and joke around with the people you are working with."

Women Beginning to Shatter the Glass Ceiling

Women are scarce in the executive ranks, though some do hold leadership positions, especially with smaller companies, and about 5 percent of board positions in the top 500 mining companies are held by women, according to recent industry reports.

More often than not, however, women still find themselves forcing down the corporate door, said Filas. Knight Piésold and Co., a global engineering and environmental consultancy, was looking outside the firm for a successor for president of U.S. operations when Filas walked into the chief executive's office with her 20-plus years of progressively responsible experience and announced that there was no need to hire from outside; she would take the job.

'It had just never occurred to him that I could fill that leadership role," she said, "but he got used to the idea quickly and was happy to promote me."

Because of the advancement of people like Filas, younger women in the industry now see potential where once there were closed doors. "There are so many more women in mining management positions," said Allison Hagerman, a member of the UA women's mine rescue team who is set to graduate in May 2013. "So much has changed."

Unlike veteran Filas, most women who major in mining and geological engineering at the UA don't start out thinking they want to be mining engineers. Despite progress, the majority still have no idea what mining and geological engineers do.

Recent graduate McMaster, who is with Barrick in Nevada, was a nursing major when she fell into mining engineering. She was taking math classes for fun when she decided to take an introductory engineering course and was invited to visit the UA San Xavier student mine. Without that invitation, she doesn't think she would have learned about the University's mining program.

"Now I know I was always meant to be underground," said the former president of the UA student chapter of the Society for Mining, Metallurgy, and Exploration.

McMaster, Barickman and their fellow female graduates – four in their class of 2012 – say it is the lack of the public's knowledge and awareness about the importance of mining, even though society depends on minerals pulled from the ground in every facet of life, coupled with the public's negative perception of mining, never mind that in recent years the mining industry has undergone myriad social, environmental and technical advancements, that keeps more women from entering the field today.

"Getting people into the industry is really just about exposure," said Barickman.

Forecast Bright for Mining Engineering Graduates

Perhaps most importantly in today's economy, recent mining and geological engineering graduates are all certain about one thing: They are cashing in on a career with a big future.

"We don't have to look for jobs; they come to us," said McMaster, who has convinced her brother, a business major, to consider working in the mining industry.

It's true, said Vicki Seppala, a returning student who graduated from the UA in 1994 with a degree in geological engineering and went on to serve as the first female mine manager in Chile.

"There is a lot of demand for talent in our industry right now. We are looking for talented people, period."

Said Filas: "Maybe women did have to jump a little higher and work a little harder to get past the preconceived notions about women in mining, but these days it doesn't matter so much whether you are male or female. Success comes from hard work and not a whole lot else."

More change may well be on the way as more and more women enter mining, it gets in their blood, and they stay.

McMaster, who works four days a week and has a three-day weekend, says her company is very family oriented. Still, as she contemplates starting her own family someday, she is looking forward to a time when she is more established and shared jobs and part-time employment create even shorter workweeks. Perhaps she won’t have to wait long. As the industry becomes increasingly more automated, and women continue to enter the workforce, "there will be more discussion about work-life balance," said Seppala. "I believe it will be addressed."

All of the UA women in the industry, whether they graduated 35 years ago or in 2013, prefer to be known for the job they do, not for the number of X chromosomes they have.

"I don't think being female makes you special, and it really bothers me when people point it out because it shouldn't matter at all," said Rita Riggs, a 2010 UA mining and geological engineering graduate and the first female to have served as mine manager at the San Xavier student mine. "It is about hiring the best people, people who are going to create safe and efficient mines."

In a world where there are many firsts still to come for women and where women likely will always be known, at least in the company of one another, as "the girls," the future seems bright for those with the gumption to buck tradition, the spirit to dig deep and get through the rigorous training, and the conviction to roll up their shirt sleeves and help get the job done.

"The success of women in the mining industry will attract more and more women to the profession," said mining and geological engineering department head Mary Poulton, "and the public benefits from that as much as the industry."

What's Up UA? - Three UA Students Named Tillman Military Scholars

Joining military veterans and their spouses from across the nation, three University of Arizona students have been named to the fifth class of Tillman Military Scholars.

The Tillman Military Scholars program is providing the 60 recipients with nearly $1.4 million in scholarship funding in recognition of their service, leadership and high academic performance.

Established by the Pat Tillman Foundation in 2008, the scholars program helps servicemembers and their families complete higher education degree programs. To date, 15 UA students have earned scholarship through the foundation.

The UA recipients are: Felisa (Hervey) Dyrud, a doctoral student in Middle Eastern literature; Adam Ratesic, who is pursuing a medical degree with a focus in rheumatology; and Jose Cervantes, also a medical student. All three of them served in the U.S. Air Force.

"The Tillman Military Scholars program plays a vital role in transitioning veterans into civilian life by fueling their potential as leaders and game changers when they return home," Marie Tillman, the Pat Tillman Foundation's president and co-founder, said in a release announcing the scholars.

"During his life, Pat refused to standby on the sidelines as an athlete and a soldier, and each Tillman Military Scholar embodies the principles of service, learning and action that he lived by everyday," Pat Tillman also noted.

"These men and women are the determined few who stepped forward to lead when duty called. Through their studies in medicine, foreign affairs, urban planning and more, they are building on Pat's legacy of leadership and creating their own to impact and inspire our country for years to come."

Dyrud, who served from 2006-12 in the U.S. Air Force, said she is honored to have been named a recipient, saying she held great respect for Tillman's choice to leave his career as a professional football player to serve in the military.

Currently in Afghanistan, Dyrud has worked with a team to establish the nonprofit organization Civil Vision International, of which she is president. The organization connects citizens in Afghanistan with those in the U.S. to promote international freedom, peace and stability.

"Our vision is to educate, inspire and connect citizens," Dyrud said. "I firmly believe that the future we are fighting for together, not only in military ways but also through education, activism and many other creative means, is worthwhile and possible."

After the UA, Dyrud – a poet who studies Persian literature with a focus on the writings of women in Afghanistan – intends to remain connected in her work with Civil Vision International.

Dyrud's last assignment was serving as the civil society team leader for the International Security Assistance Force Anti-Corruption Task Force in Kabul, Afghanistan. She also published a book, "Hearts for Sale! A Buyer's Guide to Winning in Afghanistan," under the name of Farzana Marie and detailing her experience as a military officer.

"I have a deep sense of the importance of the mission there for which Pat gave his life," said Dyrud, who has been deployed for two years. "It is winnable, it is worth it, and Pat Tillman as well as those still serving deserve all of our respect and support."

What's Up UA? - Student EMTs Give Rapid Response to Campus Emergencies

Whether it's a bicycle collision or difficulty breathing, the UA community can count on quick help from students trained and certified as EMTs.
 
The University of Arizona Student Emergency Medical Services, or UASEMS, group has been operational for three semesters and provides assistance in medical emergencies. Its leaders emphasize thorough training and certification.
 
"We're students at the UA who happen to be EMTs. We're not student EMTs," says Derek Smith, manager of UA Student Emergency Medical Services and a non-degree-seeking graduate student.
 
When Brandon Murphy arrived at the UA three years ago, he didn't find any options for students to work in EMS on campus. He met up with two other students – who've since graduated – to begin brainstorming a program that students could run. They looked at other universities that have student EMS programs and modeled a club after the best practices they found around the country. It took two years to work through the administration and risk management officials, but they were able to start as a club with ASUA funding and began responding in spring 2012.
 
UASEMS switched to funding from the student service fee and began expanding hours in fall 2012. As the fall progressed, the group did too, taking on additional days until they were operating from 6 p.m. to 6 a.m. seven days a week.
 
UASEMS this year was the sole EMS provider at the Tucson Festival of Books, saving the festival $4,000 by not using the Tucson Fire Department. UASEMS also works stand-by at Spring Fling, football games and tailgating and when requested for special events, like the Susan G. Komen Race For The Cure.
 
"Anything that occurs on campus, we can be there," Murphy says. "Our members do get put into emergencies where they're the only person there, so we make sure they're held to the same certification. We weren't going to settle for a CPR certification or anything else. We make sure everyone has state certification."
 
UASEMS finished the semester with 32 student members, most of whom are certified Emergency Medical Technicians, with the same Arizona training and certification as a Southwest Basic Life Support Ambulance. Two EMTs staff each 12-hour shift, sometimes along with an additional Certified First Responder, and typically respond to at least two calls for service. On its busiest day, UASEMS responded to 12 calls in a 24-hour period.
 
Common calls for service deal with fall victims, injuries from pedestrian, bicycle or vehicle collisions and respiratory distress.
 
"It's part of our emergency mission to provide a quick, rapid response and be the first to provide care until further medical care arrives," Murphy says.
 
By checking vital signs and reporting to paramedics, the student EMTs can eliminate a step and save valuable time if a patient needs to be taken to a hospital.
 
"There are calls where we take the blood pressure while waiting for TFD and give the information right to them so they can load and go. They appreciate it," Murphy says.
 
Many students join out of an interest in a future medical career, some have even gone on to medical school already, while others are considering EMT as a career. Interest is growing; the group has received 80 applications since the fall that they haven't been able to accept. They're hoping to take on as many as 10 in the fall and hope to expand to providing EMS service around the clock, seven days as week.
 
UASEMS has a golf cart and two bicycles, all equipped with emergency gear. UAPD ride-alongs are a mandatory part of the orientation, which includes 20 hours of vigorous bike training and instruction on bloodborne pathogens and health privacy laws. The members participate in monthly continuing education courses and perform mock drills during the week.
 
"It's real-life, in-the-field experience they can't get shadowing somebody in a hospital," says Murphy, a junior in communications from New Jersey. "Here, you're set to a standard and you have a responsibility. That is your patient until further medical attention arrives."

What's Up UA? - UA Ranks Second in U.S. for Peace Corps Coverdell Fellows

Thanks to the service-oriented nature of the University of Arizona community, the institution has for years been one of the nation's top-raking producers of Peace Corps volunteers.

And that's not all. The UA also ranked second on the newly released Peace Corps' 2013 list of top Paul D. Coverdell Fellows programs, which are administered at institutions across the nation.

For Peace Corps volunteers returning to the U.S. states, the Coverdell Fellows program provides them with scholarships, academic credit and other support toward a graduate degree. In addition to their studies, fellows are able to complete internships in underserved communities in the U.S.

"The University of Arizona has established an impressive record of top rankings in the Paul D. Coverdell Fellows program,” Janet Allen, the Peace Corps West Coast regional manager, said in a prepared release.

Today, 52 returned Peace Corps volunteers are enrolled in the UA's 12-year-old Coverdell Fellows program. Since 2001, 159 UA students have completed the program.

"I had the honor of meeting this year's Fellows cadre during the UA's Peace Corps Week," Allen also noted. "They bring an impressive wealth of Peace Corps experience to their graduate work and a strong service ethic to the UA and the greater Tucson community – it's a win for everyone."

Other institutions that made the top producing list for the Coverdell Fellows programs include the University of Denver, Johns Hopkins University and Brandeis University.

"Every year, hundreds of Peace Corps volunteers make a difference by combining meaningful service with graduate studies through Peace Corps' Master's International and Coverdell Fellows programs," Peace Corps Deputy Director Carrie Hessler-Radelet said in a statement.

"After completing Peace Corps service, volunteers return to the United States as global citizens, with leadership, cross-cultural understanding and language and technical skills that position them for success in today's global job market," Hessler-Radelet also noted.

Since 1961, a total of 1,147 UA alumni have served in the Peace Corps, with 41 currently serving overseas.

Holly Bryant, who served as a community health volunteer before becoming a fellow at the UA, said her classroom-based education was greatly reinforced through her service work.

"This allowed me to test the limits of my comfort zones and my knowledge as it is applied in the real world," said Bryant, a student in the UA Mel and Enid Zuckerman College of Public Health.

"Flexibility is the key, being able to move with the flow of what's happening in the moment," said Bryant, who served in Uganda from 2008 to 2010. "These traits were integral during my Peace Corps service."
