ISS011-E-11356 (30 July 2005) --- A new Control Moment Gyroscope (CMG) sits in its cradle in the payload bay of the Space Shuttle Discovery prior to its installation on the International Space Station. During their spacewalk scheduled for Monday, August 1, astronaut Stephen K. Robinson and Japan Aerospace Exploration Agency (JAXA) astronaut Soichi Noguchi, both STS-114 mission specialists, will replace CMG-1, which had failed in June 2002, with the new CMG bought onboard Discovery.
