NASA's Space Shuttle Processing Status Report
Note: 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. If you are a member of the media and would like further information, visit:

Mission: 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: 39B
Crew: Lindsey, Kelly, Sellers, Fossum, Nowak, Wilson and Reiter
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles

The payload bay doors of Discovery remained closed Monday and Tuesday because of the anticipated high wind and rain from Tropical Storm Alberto. Today, doors were opened for camera checkouts in the shuttle's remote manipulator system (robotic arm) and the orbiter boom sensor system. Aft closeout work continues, with technicians performing final inspections and installation of panels and thermal blankets on the avionics bays.

The STS-121 crew is conducting its Terminal Countdown Demonstration Test activities today and Thursday at KSC. This test is a launch dress rehearsal that occurs prior to each shuttle mission. Today's activities include pad egress training and systems briefings.

On Thursday, the crew will climb aboard Discovery on the launch pad for the simulated final hours of the launch countdown. On Friday, NASA managers will gather at KSC for the Flight Readiness Review that is expected to culminate on Saturday with the setting of a launch date.
