...ones. In the long and often glittery history of American space exploration, far and away the two worst ideas have been the International Space Station (ISS) and the snakebit fleet of space shuttles. For more than a generation, these two ill-considered programs have been money pits for NASA, gobbling funds and returning nowhere near enough in return. Yesterday, they took another big bite out of the space agency, when officials announced $3 billion worth of NASA budget cuts over the next five years, all of them needed to help keep the manned programs going and all of them coming...
...make a poor gatekeeper for the world’s information.Google has had more success with a recent pilot program in which they’ve agreed to digitize and put online the video content of the National Archives, including United Newsreel Motion Pictures from the Second World War, NASA documentaries from the ’60s, and a variety of other footage. Google video (video.google.com), once viewed by college students only as a tool for wasting time watching clever Super Bowl commercials and home movies of suburban teenagers blowing up Pepsi bottles with Mentos, may yet serve a more...
...they have nearly doubled their rate of flow over the past five years, to about 8 miles a year, dumping icebergs and meltwater into the already rising ocean faster than anyone expected. "In 1996 Greenland was losing about 100 cu km of ice per year," says Eric Rignot of NASA's Jet Propulsion Laboratory, lead author of the study, which he presented at last week's meeting of the American Association for the Advancement of Science in St. Louis, Mo. "This year it will lose more than twice as much." By comparison, he says, in 1996 Greenland dumped 90 times...
...interesting political note: Eric Rignot, the lead author of the Greenland study and an accompanying report in Science magazine, works for NASA?s Jet Propulsion Laboratory (the glaciers? speedup was detected with a satellite). Just a couple of weeks ago, another NASA scientist named James Hansen claimed he?d been silenced by the agency for speaking out about evidence for global warming; the resulting furor led the NASA official who was involved to resign. Hansen?s commentary on the Greenland result appears here. And when Rignot was asked yesterday whether anyone at the agency had tried to shut...
...Constellation 1, 2, and 3,” the pieces at the entrance, was thrilled to work with the variety of media her class allowed. For “Visual and Environmental Studies 123r, Post Brush,” Stinetorf silk-screened diagrams, drawings, and NASA images of constellations onto canvas, then moved to collage, adding layers of paper, cloth cut-outs, and plastic flowers to convey a depth she finds lacking in ordinary silk-screening...
