STS-135 Space Shuttle Mission Tweetup in Houston

So, you think you can pilot the space shuttle? NASA will give 30 of its @NASA Twitter followers a chance to test their skills at space shuttle ascent, rendezvous or landing aboard the same simulator astronauts use to train for their missions.

NASA's Johnson Space Center is hosting a daylong Tweetup on Tuesday, July 19, during space shuttle Atlantis' STS-135 mission to the International Space Station. Participants will get a behind-the-scenes tour at Johnson and a hands-on opportunity aboard the space shuttle simulator to take control in a training scenario.

The tour for Twitter followers includes a look at mission control and astronauts' training facilities. Visitors also will have the opportunity to speak with flight directors, trainers, astronauts and managers. The Tweetup will include a "meet and greet" session to allow participants to mingle with fellow Tweeps and the staff behind the tweets on @NASA and @NASA_Johnson.

Atlantis is targeted to launch from NASA's Kennedy Space Center in Florida at 11:26 a.m. EDT on July 8. If it launches as planned, the Tweetup will take place one day before the last orbiter of the shuttle fleet makes its final landing.

Tweetup registration opened at noon EDT on Tuesday, June 28, and closed 24 hours later at noon EDT on Wednesday, June 29. NASA will select 30 individuals randomly from the online registrants.

What is a Tweetup?
A Tweetup is an informal meeting of people who use the social messaging medium Twitter. This Tweetup is an opportunity at NASA's Johnson Space Center in Houston.

How do I register?
Registration was open at 11 a.m. CDT/noon EDT on Tuesday, June 28, on this page. NASA will accommodate 30 people who sign up. An additional registrants will be added to a waitlist. Registration was open for 24 hours.

Limit one entry per person. In the case of multiple entries for the same individual, only the first entry received will be considered. Registration is for one person (you) and is non-transferrable.

What are the registration requirements?
Registration indicates your intent to travel to NASA's Johnson Space Center in Houston and attend the event in person. You are responsible for your own expenses for travel, lodging, local transportation, food and other amenities. Once you are on-site at the Johnson Space Center, NASA will provide transportation.

NASA's Johnson Space Center is a government facility. To be admitted, you will need to show a government-issued photo identification that matches the name provided on the registration. Those without proper identification cannot be admitted. All registrants must be at least 18 years old.

Can I register if I am not a U.S. citizen?
Unfortunately, non-U.S. citizens will not be able to attend this Tweetup in Houston because of security restrictions. However, don't despair; NASA is planning other events in the future at which non-U.S. citizens will have the opportunity to participate.

Do I need to have a Twitter account to register?
Yes. This event is designed for Twitter users who follow @NASA and other NASA Twitter accounts. The goal of NASA Tweetups is to allow people who regularly interact with each other via Twitter to meet in person and discuss one of their favorite subjects: NASA.

Does my registration include a guest?
Because of space limitations, you may not bring a guest. Each registration provides a place for one person only (you). Each individual wishing to attend must submit a separate registration.

What if I cannot come to Houston?
If you cannot come to Houston to attend in person, you do not need to register for the Tweetup. However, you can still plan to follow the mission of space shuttle Atlantis on NASA TV at the NASA TV section. NASA also will provide regular launch and mission updates on @NASA and the Space Shuttle section.

If you can't make this Tweetup, don't despair; NASA is planning others in the future at various agency locations.

When will I know if I made it?
After NASA has received and processed the registrations, an e-mail with confirmation information and additional instructions will be sent to those registered and those on the waitlist. We expect to send notifications by July 5, or sooner.

What if the space shuttle's launch date changes?
The STS-135 Mission Tweetup should not be impacted by a launch delay. Even if the shuttle flight is postponed beyond the July 19 Tweetup date, NASA still will host the Tweetup in Houston on July 19.
