Nematodes ("C. elegans") from one experiment were found still alive in the debris after the Space Shuttle "Columbia" disaster. "C. elegans" are also part of experiments aboard the International Space Station as well as research using quail eggs. Earlier shuttle missions included grade school, junior high and high
