CAPE CANAVERAL, Fla. (AP) - Forgive Mark Polansky if he's been too busy to tweet lately. He is in space, after all.
Polansky, the commander of the space shuttle Endeavour, is only the second astronaut to file Twitter updates from space. He says the mission
has been so busy he's had trouble finding time to write a 140-character tweet. He says sometimes he barely has time to catch
dinner and get to bed. However, he says he's enjoyed reaching a segment of the public through Twitter who might not otherwise pay
attention to space travel.
Polansky has tweeted regularly with the help of workers at the Johnson Space Center who actually post his messages.
