Space station crew conduct spacewalk
Leroy Chiao and Salizhan Sharipov floated outside the space station for the second time this year. They erected antennas for an upcoming cargo flight, and deployed a small satellite.
The station's interior was unoccupied while the two worked outside. They did not work on a circuit breaker that caused the shutdown of one of the station's gyroscopes. That task will be left for the next crew of the ISS.
