NASA invites public to tweet their way into space

NASA is inviting the public to send questions for the astronauts abroad space shuttle Endeavour via Twitter and have them answered live from space.

Endeavour's mission to the International Space Station (ISS) will take off on February 7.

Astronaut Mike Massimino will be accepting questions for the crew from the public via his Twitter account until Thursday, February 11.

Massimino will be a shuttle Capcom, or spacecraft communicator, at NASA's Mission Control in Houston during Endeavour's flight.

On February 11, Massimino will host an interactive event with the crew from his console in Mission Control.

He will ask the astronauts as many submitted and live questions as practical during the 20-minute event.

The shuttle will be docked to the station during the live question and answer session. The event with Endeavour's crew will be broadcast live on the Web and NASA Television.

The public is invited to start tweeting questions for Endeavour's crew to Massimino's Twitter account, @astro_Mike, or add the hashtag #askastro to their tweets.

The time and day of the Twitter session are subject to change due to mission priorities.

Endeavour's 13-day STS-130 mission will include three spacewalks and the delivery of the Tranquility node, the final module of the US portion of the station.

Tranquility will provide additional room for crew members and many of the space station's life support and environmental control systems.

Attached to Tranquility is a cupola, which houses a robotic control station and has seven windows.

The windows will provide a panoramic view of Earth, celestial objects and visiting spacecraft.

After the node and cupola are added, the orbiting laboratory will be approximately 90% complete.
