throughout his career, dr. vonen some corral species nearly vanish, but now he's optimistic. >> we can't wait a hundred years that it might be a cycle that they will come back on their own. we want to headquarter them by planting thousands if not millions of tiny ones so we'll have corals here for a long time. >>> looking for the next generation in space. who nasa is looking to hire as it plans its next mission to the final frontier. >>> we can fine out more today about the future travel to mars. nasa set to unveil what it calls key scientific finings on the red planet's atmosphere. in september, a nasa spacecraft circling mars found evidence of water on the surface. every kid thinks about being an astronaut, and now is the time to make that dream come true. nasa says it will soon accept applications for the next wave of space travelers. >> reporter: nasa is looking for a few good people to make a very long trip. >> i want you to apply for nasa's astronaut program. >> reporter: it's part of the plans for future exp

using this method, dr. von says his team can produce thousands of fragments in days.se fragments are cut from corals which possess genetic characteristics that can give them a better chance of survival. in nature this coral would take about 15 years to reproduce and there's about a one in a million chance that it would be able to do so, but this new technology means that dr. von and his team are available to grow these corals to this size in less than a year. once the corals reach a certain size, they are then transplanted on to dying reefs. it's now one of the largest coral restoration projects of its kind. thanks to government grants and private donations, next year they plan to expand the program and double the amount of reef restoration. over the next decade, dr. von hopes to restore more than a thousand acres of florida's reefs. throughout his career he has seen some coral species nearly vanish, but now he is optimistic. >> we can't wait a hundred years that they may come back on their own. we want to head start them so we'll have corals here for a long time. >>

( otha vaughan, retired nasa engineer) "if it's flight hardware, you want to take care of it. if it's test hardware, you don't necessarily want to keep it. there's a bunch of relays here probably from the battery system." it's weathered and worn and missing a few parts. "what do you think it measures? 72 inches." but the specs match up. and it's johnny worley's hope that a buyer will match up when he auctions it off later this month. johnny worley, s
