BOSTON -- Space shuttle astronaut and Needham native Sunita "Suni" Williams says her return to gravity made her pretty nauseous but other than that, she's doing pretty well during her first week back on earth.

Williams was the first woman to spend more than six months on the International Space Station.

Williams set an endurance record for the longest single spaceflight by a woman at 195 days, as well as the record for most time spacewalking by a woman.

Still in Houston, Williams talked live with NewsCenter 5's David Brown about her homecoming, saying that she only felt nauseous for about 48 hours after returning to Earth.

Wearing a Red Sox cap for the interview, the Needham, Mass., native said that she is, in effect, a living space experiment for NASA, providing information on the impact of long-term space flight for humans. The information, she said, will be useful if NASA ever decides to try to send astronauts to Mars.

Williams said, having broken several records for space flights and space walks, she still has some things she'd like to do in space. She said she would be interested in a trip back to the moon.
