Video: Nasa recruiting new astronauts for International Space Station Nasa astronaut Dan Burbank, who has flown two space shuttle missions, recorded the video whilst weight-less in the International Space Station. "I've been very fortunate to have a great career with Nasa," Mr Burbank said. But now we need new astronauts to continue working on board the International Space Station conducting world class scientific research for the benefit of everyone on Earth. Nasa states that to apply candidates need a bachelor's degree in engineering, biological science, physical science, or mathematics and at least three years of related, progressively responsible, professional experience or at least 1,000 pilot-in-command time in jet aircraft. Mr Burbank added that Nasa was also looking for recruits to join the new Orion spacecraft programme. We need a new class of astronauts to build and fly Orion, our new spacecraft designed to launch the powerful space launch system rocket that, when fully evolved, will be the most powerful rocket ever built. Nasa has not stated how many new astronauts it is willing to recruit but it currently only has 61 active astronauts in its ranks.
