STATUS REPORT: ELV-040309

EXPENDABLE LAUNCH VEHICLE STATUS REPORT

Mission: Geostationary Operational Environmental Satellite (GOES-O) Launch Vehicle: Delta IV Launch Pad: Launch Complex 37, Cape Canaveral Air Force Station, Fla Launch Date: No earlier than April 28, 2009 Launch Window: 6:24 - 7:24 p m EDT

A partial charging of the GOES-O spacecraft batteries has been performed and a power command functional test of the spacecraft power subsystem has been successfully completed Spacecraft fueling operations began with the loading of oxidizer into the onboard fuel tanks on March 30 The hydrazine fuel was done on April 1

Mating GOES-O to the Delta IV rocket payload attach fitting for flight is planned for April 4 and will be followed by encapsulation into the fairing on April 6 The move to Launch Complex 37 for mating to the Delta IV is scheduled for April 14

At Launch Complex 37, checkout of the Delta IV is on schedule A simulated flight test exercising the launch vehicle systems as they will function during launch has been was successfully completed The "wet dress rehearsal," a countdown dress rehearsal with the rocket fully fueled, is planned for April 8

NASA has contracted with Boeing to build and launch the GOES-O spacecraft The NASA Launch Services Program at Kennedy is supporting the launch in an advisory role NASA spacecraft project management for GOES-O is the responsibility of NASA’s Goddard Space Flight Center After launch, once Boeing and NASA have completed on-orbit checkout and the spacecraft is operational, it will be turned over to NOAA

Mission: Lunar Reconnaissance Orbiter/Lunar Crater Observation and Sensing Satellite (LRO/LCROSS) Launch Vehicle: Atlas V Launch Pad: Launch Complex 41, Cape Canaveral Air Force Station, Fla Launch Date: No earlier than June 2, 2009 Launch Window: TBD

The launch of LRO/LCROSS has been rescheduled to no earlier than June 2 This will enable sufficient time to be built back into the Atlas V processing schedule to support launch The processing schedule became insufficient after the launch postponement of the Atlas V for the non-NASA mission currently on the launch pad

This week the LRO spacecraft team has been performing mission launch rehearsals, liftoff through lunar insertion The solar arrays are planned for installation on April 8

The LCROSS spacecraft team is performing electrical testing
