STS-123
STS-123 was a Space Shuttle mission to the International Space Station (ISS) which was flown by Space Shuttle Endeavour. STS-123 was the 1J/A ISS assembly mission. The original launch target date was February 14, 2008, but after the delay of STS-122, the shuttle was launched on March 11, 2008. It was the twenty-fifth shuttle mission to visit the ISS, and delivered the first module of the Japanese laboratory, Japanese Experiment Module (Kibō), and the Canadian Special Purpose Dexterous Manipulator, (SPDM) Dextre robotics system to the station. The mission duration was 15 days and 18 hours, and it was the first mission to fully utilize the Station-to-Shuttle Power Transfer System (SSPTS), allowing space station power to augment the shuttle power systems. The mission set a record for a shuttle's longest stay at the ISS.
STS-123 delivered the pressurized section of the Japanese Experiment Logistics Module (ELM-PS) as well as the Special Purpose Dexterous Manipulator (SPDM) to the International Space Station. The SPDM was delivered disassembled on a Spacelab Pallet (SLP) and assembled during three spacewalks once it was at the station.
In August 2007, STS-123 crew members participated in crew equipment interface tests for the ELM-PS at Kennedy Space Center. Processing continued on schedule for Endeavour's launch in early 2008. NASA engineers applied the same ECO sensor modifications used on STS-122's external tank, to Endeavour's tank. In January, a HEPA filter contamination issue was discovered, but was resolved and with no impact to the mission.
On February 11, 2008, Endeavour was "rolled over" to the Vehicle Assembly Building in preparation for mating with the external tank and solid rocket boosters. On February 13, 2008, Endeavour was successfully mated with its external tank and solid rocket boosters, and was rolled out to Launch Pad 39A in the early hours of February 18, 2008, for its planned launch on March 11, 2008. The Terminal Countdown Demonstration Test, a full dress rehearsal for launch with the crew, took place February 23–25, 2008.
The mission marked:
Flight days are based on the days as experienced by the astronauts, who are generally in a day-and-night pattern that is not equal to that of the launch site. The first flight day is the day of launch for the astronauts. That day started at the launch site on March 10, 2008 (local time), with the actual launch in the early hours of the 11th and the astronauts going to bed several hours after launch. March 10, 2008, is called flight day 1 by NASA, even though the actual mission launched on March 11.
Endeavour launched on time at 02:28:14 EDT (06:28:14 UTC) early into the night of March 11, 2008, from Launch Complex 39A at the Kennedy Space Center.
The Flash Evaporator System switched from its primary controller to the backup controller during launch, and instrumentation for a few left-side control thrusters was lost due to a card failure. These anomalies were not expected to affect the mission.
