The event will be in the James E. Webb Memorial Auditorium at NASA Headquarters, 300 E St. SW, Washington. Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandra Magnus and Rex Walheim were the crew of the space shuttle Atlantis for the 13-day STS-135 mission. Atlantis launched July 8 and landed July 21, completing NASA's final space shuttle mission, after a journey of more than five million miles. The crew delivered more than 9,400 pounds of spare parts, equipment and other supplies in the Raffaello multi-purpose logistics module -- including 2,677 pounds of food -- that will sustain space station operations for the next year. The 21-foot long, 15-foot diameter Raffaello brought back nearly 5,700 pounds of unneeded materials from the station. STS-135 was the 135th and final shuttle flight. A Tweetup is an informal meeting of people who use the social messaging medium Twitter. This NASA Tweetup is an opportunity to meet and speak with STS-135 crew members, the people behind NASA's Twitter account and other space-exploration-minded participants. Registration for the event is open from 10 a.m. EDT, Thursday, Sept. 29, until 5 p.m. on Friday, Sept. 30. NASA randomly will select 150 participants from online registrants.
