NASA's Space Shuttle Processing Status Report
NASA's Kennedy Space Center issues Space Shuttle Processing Status Reports periodically and is the source for information regarding processing activities associated with the vehicles and payloads. This report does not necessarily reflect the chronological order of future space shuttle missions.

STS-121 - 18th International Space Station Flight (ULF1.1) - Multi-Purpose Logistics Module Vehicle:
Discovery (OV-103) Location:
Launch Pad 39B Launch Date:
Launch Processing Window July 1-19, 2006 Launch Pad:
Lindsey, Kelly, Sellers, Fossum, Nowak, Wilson and Reiter Inclination/Orbit Altitude:
51.6 degrees/122 nautical miles
On Tuesday at the launch pad, Space Shuttle Discovery was powered up for technicians to perform the integrated testing of the multi-purpose logistics module Leonardo, scheduled to fly in the vehicle's payload bay to the International Space Station.
During testing, a problem was detected in left-hand solid rocket booster bus B, which is a power distribution circuit that delivers electrical power from the orbiter to the booster. This caused the system to switch to the backup circuit, bus C. Engineers have determined the integrated electronics assembly failed and needed to be replaced.
Late this week, workers will begin loading the hypergolic fuel into the solid rocket booster hydraulic power units. External Tank
The external tank scheduled to fly with Atlantis on mission STS-115 departed the Michoud Assembly Facility in New Orleans on Monday. Liberty Star, the solid rocket booster retrieval ship towing the tank, is scheduled to arrive at Port Canaveral on Friday.
