Eliminating dead bugs on Mars-bound spacecraft, designing a skin-tight space suit and retrieving small objects that float away in space stations were some of the topics that came up during an international videoconference hosted by the MIT Mars Society on May 15. “From Earth to Mars,” which was videocast to MIT students in Rm 9-057 and to five French universities, included speakers Kenneth Jewett, a Jet Propulsion Lab/NASA engineer; Dava J. Newman, associate professor of aeronautics and astronautics at MIT; and Leopold Eyharts, a French astronaut who once spent several weeks on Mir, the Russian space station.
