STS-118


Crew: Kelly Scott, Hobaugh, Caldwell, Mastracchio, Williams Dave, Morgan, Drew. ISS logistic mission. Delivered consumables, and completed necessary supplementary assembly, repair, and external equipment moves necessary for the next major stage of ISS assembly.

The mission delivered consumables, and completed necessary supplementary assembly, repair, and external equipment moves necessary for the next major stage of ISS assembly.

Space Shuttle Endeavour was launched on Aug 8 at 2236 UTC. The STS-118 stack comprised Orbiter OV-105, solid rockets RSRM-97 and external tank ET-117. The solid boosters separated 2 min after launch. At 2245 UTC the orbiter main engines cut off and ET-117 separated into an approximately 57 x 225 km x 51.6 deg orbit. The OMS-2 burn at 2313 UTC put Endeavour in a higher 229 x 317 km orbit as the ET fell back to reentry around 2346 UTC. Crew of STS-118 are Scott Kelly, Charles Hobaugh, Tracy Caldwell, Rick Mastracchio, Dafydd Williams, Barbara Morgan, and Al Drew.

During ascent a large chunk of external tank foam was observed to hit the underside of the orbiter. Examination in orbit using the robotic arm showed a hole in a heat shield tile that went down to the felt mounting pad. There was considerable press discussion of the danger, but as the mission drew to a close NASA decided that no lasting damage would be incurred during reentry to the orbiter structure, and called off a potential extra spacewalk to repair the tile.

Endeavour docked at the PMA-2 adapter on the Station at 18:02 GMT on 10 August; the hatches were opened at 20:04.

The 14036 kg of cargo broke down as follows:

  • Bay 1-2: Orbiter Docking System, 1800 kg
  • Bay 1-2: EMU 3010, 130 kg
  • Bay 1-2: EMU 3017, 130 kg
  • Bay 3: Tunnel Adapter, 112 kg
  • Bay 5-7: Spacehab-SM Single Module, 5480 kg: Loaded with research experimental equipment and consumables to be left at the station.
  • Bay 8P: SPDU: Station Power Distribution Unit, will be left at the ISS and allow the Orbiter to draw electricity from the station while docked, allowing longer missions
  • Bay 8-10: S5 Truss, 1584 kg: a short spacer truss installed at the end of the ISS S4 truss during the mission, to eliminate interference with the S6 solar panels when they would be added later
  • Bay 11-12: ESP-3, 3400 kg: External Stowage Platform 3, left at the ISS, provided external storage for spare parts, and was delivered with a spare nitrogen tank for the truss cooling system, a spare truss battery charge/discharge unit (BCDU), a spare Canadarm-2 robot arm pitch roll joint, and a replacement Control Moment Gyro for the Z1 truss
  • Bay 11-12: CMG-3R ORU, 540 kg
  • Sill: OBSS, 450 kg
  • Sill: RMS 201, 410 kg
The shuttle's RMS 201 robotic arm moved the S5 truss from the payload bay at 20:50 on 10 August. It was handed over to the station's Canadarm-2 robotic arm, which then attached it to the S4 truss at 17:30 on 11 August, with astronauts assisting on the first of four spacewalks of the mission. On 14 August, ESP-3 was unberthed from Endeavour's payload bay and attached to the P3 truss on the Station, where its spare parts can be reached if needed.

Following successful completion of all cargo delivery and station assembly tasks, the crew returned to Endeavour on 18 August, undocking the next day at 11:56 GMT. Landing was moved up a day ahead of schedule because of concern a hurricane might force evacuation of the Houston Control Center on the originally-planned return date. Endeavour began its deorbit burn at 15:25 GMT on August 21 and lowered its orbit from 336 x 347 km to -28 x 342 km. It landed on runway 15 at Kennedy Space Center at 16:32 GMT. Landing mass was 100,878 kg.

Before the Columbia disaster the mission was to have been flown on 13 November 2003 with the crew of Kelly Scott, Hobaugh, Parazynski, Williams Dave, Morgan, and Nowak. It would have delivered the a Spacehab Single Cargo Module with station supplies, and the third starboard truss segment (ITS S5). The crew would have attached the S5 Truss to the station. In the post-Columbia rescheduling, the mission became a simple resupply mission, and Parazynski was moved to STS-120. Mastracchio was moved from STS-118 to STS-120. Nowak was deleted from the crew after her arrest in Florida on kidnapping charges in February 2007.

AKA: Endeavour; ISS-13A.1.
First Launch: 2007.08.08.
Last Launch: 2007.08.21.
