NASA Tweetups (re-branded NASA Socials in 2012) are events hosted by NASA to promote the agency's missions through social media. Elmo attended the NASA Tweetup on July 7-8, 2011 for what would be the final launch of Space Shuttle Atlantis. Elmo appeared at Cape Canaveral, Florida speaking with astronauts Leland Melvin, Mike Massimino and Douglas H. Wheelock for a press event, and tweeted updates on the Sesame Street Twitter account.
