NASA Announces Tweetup in Northern California to Tour Airborne Observatory
NASA will host a Tweetup for 50 of its Twitter followers on Oct. 14 at the agency's Ames Research Center in Moffett Field, Calif., in the heart of Silicon Valley. The Tweetup includes a tour of the Stratospheric Observatory for Infrared Astronomy (SOFIA) aircraft.

SOFIA is a highly modified Boeing 747SP aircraft that carries a telescope with a 100-inch reflecting mirror that conducts astronomy research not possible with ground-based telescopes. SOFIA is housed at NASA's Dryden Aircraft Operations Facility in Palmdale, Calif. On Oct. 14, SOFIA will be visiting Ames.

In addition to climbing aboard SOFIA, the Tweetup guests will speak with NASA officials, managers and SOFIA scientists. The Tweetup will include a session where participants can mingle with fellow Tweeps and the staff behind the tweets on @NASA, @NASAAmes and @SOFIATelescope.

What is a tweetup?
A Tweetup is an informal meeting of people who use the social messaging medium Twitter. This Tweetup is an opportunity to learn more about NASA Ames Research Center and the SOFIA mission.

How do I register?
Registration is now closed. It was open from 7 a.m. PDT (10 a.m. EDT) on Monday, Oct. 3 until 2 p.m. PDT (5 p.m. EDT) on Tuesday, Oct. 4. NASA will randomly select 50 participants from online registrations. Additional registrants will be placed on a waiting list. Registration is for one person only (you) and is non-transferable.

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.

What are the registration requirements?
Registration indicates your intent to travel to NASA's Ames Research Center in California and attend the event in person. You are responsible for your own expenses for travel, accommodation, food and other amenities.

SOFIA is a research aircraft whose flights are contingent upon strict conditions. In the event the aircraft cannot make it to for the Tweetup Oct. 14, participants would still be invited to participate in Tweetup activities at Ames.

NASA's Ames Research Center is a government facility. To be admitted, you will need to show a government-issued identification (driver's license or passport) 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?
Yes, non-U.S. citizens may register to attend the Tweetup. However, you will need to complete an additional step to receive clearance to enter the secure areas at Ames. Please choose the "non-U.S. citizen" option in the state drop-down menu during registration. On-site, you will need to show government-issued photo identification, such as a passport, that matches the name provided on the registration. Those without proper identification cannot be admitted. All registrants must be at least 18 years old.

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. Each individual wishing to attend must register separately.

What if I cannot come to California?
If you cannot come to California to attend in person, you do not need to register for the Tweetup. However, you can still plan to follow the Tweetup on Ustream. NASA also will provide Tweetup updates on @NASAAmes.

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

When will I know if I made it?
After NASA has received and processed the registrations, email notifications will be sent to all registrants. Those selected and on the waitlist will receive confirmation information and additional instructions. We expect to send notifications
on Oct. 6.
