In this photo, courtesy of NASA/SETI, University of Khartoum students push their bus while one of them guards a little piece of asteroid 2008 TC3 found when they exited the stuck vehicle. Among all the news about the hundreds of recovered fragments, there is this remarkable note from NASA: "ten different meteorite types have been identified ... 'even though we are certain they came from the same asteroid.'"
