NASA's getting Twitter-ific. Not only is astronaut Mike Massimino tweeting updates in preparation for the Hubble mission scheduled to launch Monday, in NASA's next shuttle mission to the International Space Station in June, shuttle commander Mark Polansky is inviting followers to submit video questions via YouTube that he will answer from orbit, via Twitter.
To submit a question, Polansky's Twitter followers (about 2,300 right now, compared to Massimino's over 200K, whoops!) should post a video question no longer than 30 seconds to YouTube and tweet the link to Polansky's account, @Astro_127. From now through the launch of STS-127, one or two of the questions submitted will be selected each week to be answered from orbit.
Polansky will command Space Shuttle Endeavour during the mission. The videos will be transmitted to orbit during the mission and answered live during a special event that will be broadcast on NASA Television and posted to Polansky's Twitter and YouTube pages.
On the flight, Polansky's crewmates are Pilot Doug Hurley and Mission Specialists Dave Wolf, Christopher Cassidy, Tom Marshburn, Julie Payette and Tim Kopra. Wolf, Cassidy, Marshburn and Kopra will perform the mission's five spacewalk, while Kopra will remain aboard the station after Endeavour departs as a flight engineer for Expedition 20.
Meanwhile, Koichi Wakata, a Japan Aerospace Exploration Agency astronaut, will return to Earth on Endeavour to conclude his three-month stay at the station. The mission is Polansky's second space shuttle command and third spaceflight.
