ISS logistics flight. Delivered equipment and supplies aboard the Leonardo cargo module.

AKA: Discovery;ISS-ULF1.1. Launched: 2006-07-04. Returned: 2006-07-17. Number crew: 6 . Duration: 12.78 days.

The shuttle was launched using external tank ET-119 and solid motors RSRM-93. Cameras revealed that large chunks of foam were still shed from the external tank during the ascent to orbit. However examination of the heat shield using a new extension and sensors attached to the shuttle's robot arm revealed no significant damage. Discovery docked with the PMA-2 adapter on the Destiny module of the ISS at 14:52 GMT on 6 July. On July 7 the Leonardo cargo module was moved from the shuttle payload bay by the robot arm and docked to the Unity Module of the ISS between 09:42 and 11:50 GMT. The crew then began unloading the spare parts and supplies in the module to the station. A series of three EVAs conducted on 8 to 12 July tested the new equipment and techniques for repairing the shuttle heat shield in case of damage, and did some preliminary installations on the exterior of the ISS to pave the way for continued station assembly missions. On 14 July, the station's SSRMS robot moved the Leonardo module from the station back to the shuttle cargo bay between 13:08 and 14:50 GMT. The shuttle separated from the ISS, and fired its engines at 12:07 GMT on 17 July to make a 92 m/s deorbit maneuver. Discovery landed at the Kennedy Space Center at 13:14 GMT. European astronaut Reiter was left behind to make up part of the EO-13 resident crew on the station.

Launch: July 4, 2006, at 2:38 p.m. EDT. Launch of Discovery was scrubbed twice, July 1 and 2, due to weather concerns. After a day's standdown, the launch attempt resumed on July 4 and Discovery lifted off on time.

Landing: July 17, 2006, at 9:15 a.m. EDT. Runway 15 at Kennedy Space Center. Main gear touchdown: 9:14:43 a.m. Nose gear touchdown: 9:14:53 a.m. Wheel stop: 9:15:49 a.m. Rollout distance: 4.2 miles. Mission duration: 12 days, 18 hours, 37 minutes and 54 seconds. Logged 5.3 million miles. Landed on first opportunity at Kennedy, marking the 62nd landing at the center.

Mission Highlights:

STS-121 was the second return-to-flight mission, demonstrating techniques for inspecting and protecting the shuttle's thermal protection system and replacing critical hardware needed for future station assembly. The mission also restored the station to a three-person crew for the first time since May 2003, leaving ESA astronaut Reiter aboard to join Expedition 13.

This was the most photographed shuttle mission in history, with more than 100 high-definition, digital, video and film cameras documenting the launch and climb to orbit. The images helped assess any damage sustained and potential risk for landing. In addition, the crew used the orbiter boom sensor system with a laser dynamic range imager, laser camera system and intensified television camera on the end, to examine the shuttle's nose cap, port wing, leading edge of the starboard wing, and outside of the crew cabin. No risk was found.

After docking to the station, the crew transferred the multi-purpose logistics module Leonardo to the Unity module from which they moved 7,400 pounds of supplies and equipment during their stay. The cargo included a new heat exchange for the common cabin air assembly that collects condensation out of the air on the station, a new window and window seals for the Microgravity Sciences Glovebox, and a spare U.S. extravehicular activity suit and emergency jet pack.

Astronauts performed three spacewalks:

EVA No. 1 -- 7 hours, 31 minutes. Mission Specialists Piers Sellers and Michael Fossum installed a blade blocker on the S0 truss in the zenith interface umbilical assembly to protect the undamaged power, data and video cable. They rerouted the cable through the IUA in order to move the mobile transporter rail car and replace the trailing umbilical system with the severed power and data cable. After that task, they tested the combination of the shuttle robotic arm and OBSS as a platform for spacewalking astronauts to repair a damaged orbiter if ever needed. The EVA was the fourth for Sellers and first for Fossum.

EVA. No. 2 -- 6 hours, 47 minutes. Sellers and Fossum restored the station's mobile transporter car to full operation, replacing the nadir-side trailing umbilical system, including a new interface umbilical assembly without a blade (the previous IUA had a blade, which inadvertently cut the cable that required the replacement). During the spacewalk, Fossum's emergency jet thruster backpack came loose on one side, requiring Sellers to secure it.

EVA No. 3 -- 7 hours, 11 minutes. The third and final spacewalk focused on testing repairs on thermal protection system reinforced carbon-carbon panels. Under evaluation was a pre-ceramic polymer sealant containing carbon-silicon carbide powder known as NOAX for use on damaged panels. Sellers and Fossum made three gouge repairs and two crack repairs. They also photographed the samples, as well as an area of Discovery's port wing. An added task during the EVA was removing the fixed grapple bar on the integrated cargo carrier in Discovery's payload bay and installing it on an ammonia tank inside the station's S1 truss to facilitate moving the tank on a later mission.

Refilled with 4,600 pounds of experiment samples, broken equipment and trash to be returned to Earth, Leonardo was moved back to Discovery's payload bay.

The return flight to Earth was delayed one day in order to add the third spacewalk. The mission management team determined there were enough consumables to extend the mission to test repair techniques and test a thermal imaging camera.

The trip home was one crew member short. Reiter remained behind to join Expedition 13, marking the first time since May 2003 that the station houses three crew members.

After unberthing from the station, the shuttle crew again used the robotic arm and boom sensors to inspect the starboard wing and nose cap heat shield. Still no concerns were noted.

Statistics

Cargo loaded in the payload bay was as follows:

  • Bays 1-2: Orbiter Docking System - about 1800 kg
  • Bay 4S: APC with SPDU - about 20 kg
  • Bays 5-6: Integrated Cargo Carrier (ICC) - about 1500 kg, with Keel Yoke Device (KYD), Trailing Umbilical System) for an ISS Mobile Transporter repair, EATCS-PM pump module for the ISS truss, and a fixed grapple bar.
  • Bay 7S: ROEU - about 20 kg
  • Bays 7-12: Leonardo cargo module (MPLM-1) - 9500 kg - with the MELFI freezer rack, the Express Transportation Rack with the European Modular Cultivation System, the Oxygen Generation System rack, three Resupply Stowage Racks and five Resupply Stowage Platforms with consumable supplies. A Remotely Operated Electrical Umbilical mounted on the sidewall routed power to Leonardo.
  • Bay 13: Lightweight MPESS Carrier with DTO 848 protection system repair kit demonstator - 954 kg
  • Sill-mounted: OBSS 202 robot arm extension, that would allow an astronaut to be carried underneath the shuttle for inspection and repairs - about 450 kg, and RMS 303 robot arm - 390 kg
  • Total cargo mass: about 14594 kg
