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

    Friday, June 14, 2013 12:33 pm

    "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."

  9. article Such the Spot - Please don't feed the children

    Friday, June 14, 2013 4:00 am

    I have a pet peeve. Who am I kidding? I have many of them, actually, but today I’m focusing on just the one. It pertains to my children. Here’s the scoop: I’m really fed up with people offering food to my children (pun totally intended). It happens all of the time. At church, for example. My children attend Sunday School while my husband and I are in the congregation at church. The service—and subsequently, Sunday School lessons—last an hour. One hour. The 10:30 a.m hour, at that. On any given Sunday, my family will typically enjoy a fairly hearty weekend treat of a breakfast. Waffles or pancakes or biscuits and eggs. By the time we drop the kids off in their respective Sunday School classrooms, scarcely an hour has passed since my family sat down for breakfast. Yet, when we pick them up from Sunday School, we hear reports of snacks that were given out. And I’m not talking about something healthy like a handful of grapes or a segment of orange. I’m talking about powdered donuts or cookies or packaged cereal bars—food imposters laden with sugar and preservatives.

  13. article What's Up UA? - Marks on Martian Dunes May Reveal Tracks of Dry-Ice Sleds

    Wednesday, June 12, 2013 11:41 am

    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.

  16. article Sports Perspective: Mayweather vs. Alvarez

    Wednesday, June 12, 2013 4:00 am

    The sporting world, in its very nature, harbors an inherent athletic Darwinism. The strong continually trump the weaker opponents, until only two competitors remain. However, this inborn trait of competition becomes complicated, and is often compromised in the sport of boxing. It is a sport in which weight classes and multiple league promotions become barriers that rob fans of dream matchups. Given this complicated boxing climate, it often becomes difficult for polarizing figures of the sport to cement their legacy as all time greats unless they take enormous risks by fighting out of their normal weight class. And amongst current pugilists, there are none more polarizing than the eccentric Floyd “Money” Mayweather.
