A prototype device created by a University of Kansas student could eventually be used by NASA to help develop a radar that could travel to Mars. Using a fellowship from the space agency, Carl Leuschen worked four years on a prototype radar that he hopes could help find water on the Red Planet. Leuschen worked on the project while earning his doctorate degree in electrical engineering. He will graduate in December. “Water on Mars can help us understand the history of the planets,” Leuschen said. “One of the goals is to find if there is life on Mars. Water would be some indication there might be.” Finding water also could pave the way for manned missions to Mars.
