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

Technicians continue performing system testing on Space Shuttle Discovery while the vehicle is powered at Launch Pad 39B Auxiliary power units No 1 and 3 connections and leak checks were completed, with No 2 in progress

The orbiter payloads were installed in Discovery's payload bay on Wednesday Discovery's payloads include the Italian-built logistics module Leonardo, which will carry food, clothing, spare parts and research equipment to the International Space Station Other payloads include two cargo carriers which contain heat shield tile samples, a spare pump module and a replacement mobile transporter reel assembly

There is no significant holiday weekend work planned

Mission: STS-115 - 19th International Space Station Flight (12A) - P3/P4 Solar Arrays Vehicle: Atlantis (OV-104) Location: Orbiter Processing Facility Bay 1 Launch Date: No earlier than Aug 28, 2006 Launch Pad: 39B Crew: Jett, Ferguson, Tanner, Burbank, MacLean and Stefanyshyn-Piper Inclination/Orbit Altitude: 51 6 degrees/122 nautical miles

In Orbiter Processing Facility bay 1, technicians are carrying out powered-up system testing on Atlantis for its mission to the International Space Station Gaseous nitrogen leak checks are finished in the orbiter's mid-body

The remote manipulator system, or "shuttle arm," was installed and functional testing has been completed Workers also finished testing the manipulator positioning mechanisms, which are the pedestals that hold the arm in place in the payload bay during launch and landing

On Wednesday, the crawler transporter moved mobile launcher platform No 2 into high bay 3 of the Vehicle Assembly Building in preparation for stacking operations to begin for the STS-115 mission The first solid rocket booster segment is scheduled to be lifted into the high bay next week
