Five middle school students with the Cornell Cooperative Extension of Jefferson County's 4-H Youth Development Program in Watertown, N.Y., assemble an experiment for the International Space Station. The youths were hosted by Cornell University where they prepared their investigation of the effects of microgravity on rust removal. The experiment will be delivered to the space station by a SpaceX Falcon 9 rocket which is currently scheduled for a July 21 liftoff.
