Work in progress: Processing of Space Shuttle Endeavour has resumed at
Launch Pad 39A following the holiday downtime. Just prior to the holidays,
workers completed launch pad validations and conducted a hotfire test of all
three auxiliary power units. In addition, Endeavour’s three main engines
underwent flight readiness tests. Shuttle workers then configured the
Shuttle for an eight-day holiday break.

Today, technicians are preparing for Friday’s helium signature leak test and
conducting routine leak checks on main engine No. 3. Tomorrow, the launch
team will assemble in firing room No. 3 to participate in a launch countdown
simulation. Loading of prelaunch propellant into Endeavour’s onboard
storage tanks begins Monday. Terminal Countdown Demonstration Test
activities with the flight crew are slated to occur Jan. 13 and 14.

Processing Milestones:

Helium signature leak test (Jan. 7)

Prelaunch propellant loading (Jan. 10-12)

Terminal Countdown Demonstration Test (Jan. 13-14)

MISSION: STS-101 – 3rd ISS Flight (2A.2) – SPACEHAB DM

VEHICLE: Atlantis/OV-104

installed before the holidays. This week, technicians are conducting wiring
inspections and repairs in the orbiter’s midbody and aft compartments.
Engineers also plan to check out Atlantis’ replaced orbiter maneuvering
system pods later this week.

Work in progress: Processing of orbiter Discovery has resumed in OPF bay 1.
Workers drained the vehicle’s onboard cryogenic reactants after a Dec. 27
landing and then secured Discovery for the transition to year 2000.
Preparations are now under way to open Discovery’s payload bay doors later
this week. Next week, work begins to remove any residual hypergolics from
Discovery’s storage tanks.
