STATUS REPORT: S05-033
NASA'S SPACE SHUTTLE PROCESSING STATUS REPORT
Discovery (OV-103)
Mission: STS-114 - 17th ISS Flight (LF1)
Payload: Multi-Purpose Logistics Module
Location: Launch Pad 39B
Launch Date: No earlier than July 17, 2005
Launch Pad: 39B
Crew: Collins, Kelly, Noguchi, Robinson, Thomas, Lawrence and Camarda
Inclination/Orbit Altitude: 51.6 degrees/122 nautical miles
Space Shuttle managers say the launch of NASA's Space Shuttle Return
to Flight mission, STS-114, will take place no earlier than Sunday,
July 17. If Space Shuttle Discovery does launch Sunday, it would lift
off at 2:14 p.m. EDT.
Mission Management Team and engineering meetings took place last night
and today at NASA's Kennedy Space Center. Team members reviewed data
and possible troubleshooting plans for the liquid hydrogen tank
low-level fuel cut-off sensor. The sensor failed a routine prelaunch
check during the launch countdown yesterday afternoon, causing
mission managers to scrub Discovery's first launch attempt. The
sensor protects the Shuttle's main engines by triggering their
shutdown in the event fuel runs unexpectedly low. The sensor is one
of four inside the liquid hydrogen section of the External Tank (ET).
A new official launch date will be scheduled once a troubleshooting
plan is complete and engineers are working on a solution. Space
Shuttle Program managers plan a series of meetings tomorrow to
discuss the problem and finalize the troubleshooting plan.
The launch control team began troubleshooting while the liquid oxygen
and liquid hydrogen were drained from the ET last night. The No. 2
liquid hydrogen sensor in the External Tank's liquid hydrogen tank
continued to read "wet" and did not transition to a "dry" indication
once the tank was completely drained. Following detanking operations,
the same commands that were sent during the launch countdown were
repeated while draining. While going through commands, sensor No. 2
continued to show "wet" instead of "dry." The firing room then
reissued commands and the sensor went to "dry" as it should have.
Another round of commands was sent and sensor No. 2 performed as
expected, with all sensors in the "dry" state.
Space Shuttle Discovery remains at Launch Pad 39B. The Rotating
Service Structure was rotated back around the vehicle last night.
The STS-114 crew, led by Commander Eileen Collins, remains at Kennedy
Space Center while engineers assess the problem. During their 12-day
Return to Flight mission to the International Space Station,
Discovery's seven crew members will test new techniques and equipment
designed to make Space Shuttle missions safer. They'll also deliver
supplies and make repairs to the Space Station.
