Twin astronauts will tweet about space

Twin brothers who will command the space shuttle and International Space Station are tweeting about their preparations, NASA says.

Mark and Scott Kelly are preparing for 2010 missions. Mark is commander of the space shuttle mission STS-134 and Scott is commander of state Expedition 26. If schedules don't change, they could meet in space.

Both West Orange, N.J., natives are Navy captains who have been astronauts since 1996. Mark served as the pilot on missions STS-108 in 2001 and STS-121 in 2006 and commanded STS-124 in 2008. He has logged 38 days in space.

Scott served as the pilot on mission STS-103 in 1999 and commanded STS-118 in 2007. He logged 21 days in space and is preparing for a six-month stay aboard the station.
