Endeavour is due to undock from the space station Sunday night at 8:55 PM Phoenix time (0355 30 May UTC) after nearly two weeks visiting the orbiting lab.

During the mission to the ISS, the Russian Soyuz spacecraft TMA-20 returned to Earth with astronauts Cady Coleman, Paoli Nespoli, and Russian cosmonaut Dmitri Kondratyev.

Following detachment from the space station, the crew of TMA-20 photographed the ISS and Endeavor. Details here.

During the current (and last visit) by Endeavour, four spacewalks were performed:

  • EVA 1. 19 May – Retrieve Materials International Space Station Experiment-7 (MISSE-7) from the ELC 2 and install in Endeavour’s payload bay, and installation of MISSE-8. Install P3-P4 ammonia jumpers. Install P5-P6 ammonia jumpers. Install wireless communications for Destiny Lab.
  • EVA2. 21 May – Began with rerouting the P3-P4 ammonia jumpers. The Solar Alpha Rotary Joint (SARJ) was exposed and lubricated, as was the Special Purpose Dexterous Manipulator (SPDM). And the ammonia system was vented.
  • EVA3. 25 May – Work was performed on the Zarya module, including installation of the Power Data Grapple Fixture (PDGF) and a variety of cables.
  • EVA4. 26 May – The 162nd and FINAL Space Shuttle spacewalk. The Orbiter Boom Sensor System (OBSS) was transferred from Endeavour to the ISS (at the Starboard 0 / starboard 1 truss interface) and a PDGF was installed so that the SPDM can attach it.

Coverage of the return will be on NASA TV.

Cady Coleman returned from 157 days on the International Space Station. The Russian TMA-20 spacecraft undocked from the station’s Rassvet module May 23, 2011, at 2:35 PM Phoenix time (2135 UTC). The crew landed safely at 7:27 PM (0227 UTC) southeast of the town of Dzhezkazgan, Kazakhstan.

Air Force Colonel Catherine Coleman flew aboard the Soyuz TMA-20 spacecraft to serve as a flight engineer for Expeditions 26 and 27. A veteran of two shuttle missions, Coleman’s last spaceflight was in July 1999 as the lead mission specialist for STS-93 aboard Columbia.

On STS-93, she was responsible for the deployment of the Chandra X-Ray Observatory.

Coleman’s first flight was aboard STS-73 Columbia from 20 October to 5 November 1995. The mission focused on materials science, biotechnology, combustion science, the physics of fluids, and numerous scientific experiments housed in the pressurized Spacelab module.

Since 1992, she has been heavily involved with astronaut training during her career at NASA
