What are the registration requirements?
Registration indicates your intent to travel to NASA's Wallops Flight Facility in Virginia and attend the three-day event in person. You are responsible for your own expenses for travel, accommodation, food and other amenities.

Some events and participants scheduled to appear at the event are subject to change without notice. NASA and Orbital Sciences are not responsible for loss or damage incurred as a result of attending. NASA and Orbital Sciences, moreover, are not responsible for loss or damage incurred if the event is cancelled with limited or no notice. Please plan accordingly.

Wallops is a government facility. Those who are selected will need to complete an additional registration step to receive clearance to enter the secure areas. To be admitted, you will need to show two government-issued identifications (one with a photo) that match 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?
Because of the security deadlines, registration is limited to U.S. citizens. If you have a valid permanent resident card, you will be processed as a U.S. citizen. Those who are selected will need to complete an additional registration step to receive clearance to enter the secure areas. To be admitted, you will need to show two government-issued identifications (one with a photo) that match 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 (you) and is non-transferable. Each individual wishing to attend must register separately.

What if I cannot come to Virginia?
If you cannot come to Wallops to attend in person, you should not register for the NASA Social. You can follow the conversation using the #NASASocial hashtag on Twitter. NASA may broadcast a portion of the program on April 16. NASA and Orbital Sciences will provide regular launch and mission updates on @NASA, @NASA_Wallops and @OrbitalSciences.

If you cannot make this event, don't despair; NASA is planning others in the near future. Check for future events at http://www.nasa.gov/social.

When will I know if I am selected?
After registrations have been received and processed, a notification email will be send out to inform you whether or not you have been selected for NASA social media accreditation. Those selected will be required to complete an additional step before being accredited. We will send notifications upon approval.

If you do not make the registration list for accreditation, you can still attend the launch and participate in the conversation online.

What if the launch date changes?
Hundreds of different factors can cause a scheduled launch date to change multiple times. The targeted launch date will not be confirmed until after the Flight Readiness Review. If the launch date changes, NASA and Orbital Sciences may adjust programming accordingly to coincide with the new target launch date. NASA will notify registrants of any changes by email.

Attendees are responsible for any additional costs they incur related to any launch delay. We strongly encourage participants to make travel arrangements that are refundable and/or flexible.

Does registration for and/or attendance at this NASA Social qualify me for media accreditation?
No, your registration and/or attendance, does not qualify you for news media credentials at NASA now or in the future.
