STATUS REPORT: ELV-060608
EXPENDABLE LAUNCH VEHICLE STATUS REPORT
Mission: GLAST (Gamma-ray Large Area Space Telescope)
Launch Vehicle: Delta II 7920-H (United Launch Alliance)
Launch Pad: 17-B
Launch Date: No earlier than June 11, 2008
Launch Window: 11:45 a.m. - 1:40 p.m. EDT
NASA is targeting no earlier than June 11 for the launch of the GLAST
spacecraft aboard a United Launch Alliance Delta II rocket. The
launch window extends from 11:45 a.m. to 1:40 p.m. EDT and remains
unchanged through Aug. 7.
The additional time is necessary to allow for replacement of the
rocket's Flight Termination System battery which displayed
indications of a problem Wednesday.
Loading of the hypergolic propellants into the Delta II second stage
is planned for this weekend. On launch day, June 11, the mobile
service tower will be retracted from around the rocket at 2 a.m. The
terminal countdown sequence will begin at 9:15 a.m. by loading the
first stage with RP-1 fuel, a highly refined kerosene. This will be
followed at 10:15 a.m. by cryogenic fueling, loading the first stage
with liquid oxygen. This will lead to a liftoff targeted for 11:45
a.m. EDT.
Mission: OSTM/Jason-2
Location: Astrotech payload processing facility, Vandenberg Air Force
Base
Launch Vehicle: Delta II 7320 (United Launch Alliance)
Launch Pad: Space Launch Complex 2, Vandenberg Air Force Base
Launch Date: No earlier than June 19, 2008
Launch Window: 12:59 a.m. - 1:08 a.m. PDT
At the Astrotech payload processing facility on north Vandenberg, the
OSTM/Jason 2 spacecraft is ready for transportation to Space Launch
Complex 2 for mating with the Delta II rocket. An initial attempt was
planned for Monday, June 2, but was postponed due to high wind. These
windy conditions have continued throughout the week and have
precluded shipping of the encapsulated spacecraft to the launch pad
and hoisting of the spacecraft into the mobile service tower.
Technicians hope the wind will begin to diminish sometime over the
weekend. Launch has been retargeted for no earlier than June 19.
