Two Astronauts Take Spacewalk, Precautions
The two International Space Station astronauts began a spacewalk this morning to install antennas and to release a small satellite, officials at NASA’s Kennedy Space Center said.
Cmdr. Leroy Chiao and his Russian crewmate, Salizhan Sharipov, left the space station empty for the second time in a few months.
They took extra safety measures, officials said, because of a problem during their spacewalk in January, when Chiao got too close to firing thrusters.
Complicating the spacewalk is a seriously hampered stabilization system following the loss of power to a gyroscope.
