RELEASE: 11-327

150 OF NASA'S TWITTER FOLLOWERS WILL BE INVITED TO MARS ROVER LAUNCH

WASHINGTON -- NASA will host a two-day launch Tweetup for 150 of its
Twitter followers on Nov. 23 and 25 at the agency's Kennedy Space
Center in Florida. The Tweetup is expected to culminate in the launch
of the Mars Science Laboratory Curiosity rover aboard an Atlas V 541
from Cape Canaveral Air Force Station. The launch window opens at
10:21 a.m. EST on Nov. 25.

The Tweetup will provide NASA's social media followers with the
opportunity to tour Kennedy Space Center; speak with scientists and
engineers; and, if all goes as scheduled, view the spacecraft launch.
The event also will provide participants the opportunity to meet
fellow tweeps and members of NASA's social media team.

Curiosity's arrival at the Red Planet is anticipated in August 2012 at
Gale crater. During the two-year prime mission, the rover will
investigate whether a selected area of Mars offered environmental
conditions favorable for microbial life and for preserving evidence
about life if it existed.

Mars Science Laboratory is the fourth space mission launching this
year managed by NASA's Jet Propulsion Laboratory in Pasadena, Calif.,
making 2011 one of the busiest ever in planetary exploration.
Aquarius launched June 10 to study ocean salinity; Juno launched Aug.
5 to study the origins and interior of Jupiter; and the twin GRAIL
orbiters departed for the moon on Sept. 10.

Tweetup registration opens at noon on Wed, Oct. 5, and closes at noon
on Fri., Oct. 7. NASA will randomly select 150 participants from
online registrations.
