STS-132

[15] Rassvet was outfitted with ISS standard grapple fixtures that allowed the module to be unloaded from the payload bay of Atlantis using the station's robotic arm.Also on board Atlantis was the Integrated Cargo Carrier-Vertical Light Deployable (ICC-VLD2) pallet, holding a Ku-band Space to Ground Antenna (SGANT), the SGANT boom assembly, an Enhanced Orbital replacement Unit (ORU) Temporary Platform (EOTP) for the Canadian Dextre robotic arm extension, Video and Power Grapple fixtures (PVGF) and six new battery ORUs.[17] In addition to the standard Official Flight Kit (OFK) flown inside a locker on the mid-deck, two Light Weight Tool Stowage Assemblies were modified to fly memorabilia and then were stowed to the left and right of Atlantis' airlock in the shuttle's payload bay.[18] A compact disk (CD) containing the digital copies of all entries submitted to NASA's Space Shuttle Program Commemorative Patch Contest[19] was also flown aboard Atlantis.The Tweetup participants met with shuttle technicians, managers, engineers and astronauts, took a tour of the Kennedy Space Center and viewed the launch of Atlantis.Short-term experiments included: The mission's external tank, ET-136, began its 900-mile (1,400 km), six-day journey across the Gulf of Mexico from NASA's Michoud Assembly Facility in New Orleans, Louisiana, on February 24, 2010.After docking in the turn basin at the Kennedy Space Center, the tank was offloaded and driven to the Vehicle Assembly Building (VAB) on March 1, 2010.[36] Given that this was at the time believed to be Atlantis' final rollover for a mission, the shuttle stopped for several hours en route to the VAB, allowing engineers and technicians to pose for photographs with the orbiter.[37] The rollover occurred exactly 25 years after Atlantis first arrived at the Kennedy Space Center, after a cross-country trip from the shuttle factory in Palmdale, California.[38] The path to the rollover was without any incidents of major concern, with only 22 Interim Problem Reports (IPRs) noted during Atlantis' flow since its return from the STS-129 mission in November 2009.Similar events occurred during Atlantis' STS-129 mission in November 2009 when Shuttle and Station crew were awakened consecutive nights by false depressurization and fire alarms that originated from the MRM-2 (Poisk) module.He further elaborated on the predicted weather conditions at the Transoceanic Abort Landing (TAL) sites: Zaragoza and Moron in Spain, and Istres, France, in case of an emergency.Powered flight conformed to the standard timeline, with main engine cutoff (MECO) occurring at 8 minutes and 32 seconds Mission Elapsed Time (MET).[54] More than 39,000 guests, including television host David Letterman, Apollo astronaut Buzz Aldrin, and former NASA administrator Michael Griffin, witnessed the launch.[56] Once in orbit, the crew opened the shuttle's payload bay doors, activated the radiators and deployed the Ku band antenna successfully.Before the thermal protection checkout began, the crew encountered a problem with the Laser Dynamic Range Imager (LDRI) and the Intensified TV Camera (ITVC), due to a snagged cable in that system's pan and tilt unit.At 11:40 UTC, with about 9 miles (14 km) separating the shuttle and the ISS, commander Ken Ham performed the final 12-second terminal initiation (TI) burn, firing the left OMS engine of Atlantis.By 13:26 UTC, with Ken Ham flying the shuttle from the aft flight deck, Atlantis positioned itself beneath the ISS and began the 360-degree flip rendezvous pitch maneuver (RPM).[63][64] After docking, the ISS was reoriented by the small vernier thrusters on Atlantis to minimize the risk of Micro-Meteoroid Orbital Debris (MMOD) impacts upon the shuttle.Mission Specialists Reisman and Bowen spent the night in the Quest airlock as part of the overnight campout procedure to help them get prepared for the spacewalk.After the morning wakeup call, Mission Control CAPCOM Shannon Lucid informed the shuttle crew that no detailed flight inspection would be required on the next day.[67] The pair installed a spare Space To Ground Antenna (SGANT), a new enhanced tool platform for the Special Purpose Dexterous Manipulator (SPDM, also known as Dextre) and released torque on the six new batteries for the Port 6 (P6) truss segment.Mission Specialists Garrett Reisman and Piers Sellers, working from inside the station's Cupola, then maneuvered the Canadarm2 arm to deliver MRM-1 to its new position, the Earth-facing port of the Zarya service module."[74] Expedition 23 Commander Oleg Kotov also monitored the activities from the Russian segment, as the MRM-1 began its automated docking sequence for the final attachment to the Zarya module.[76] After midday, Reisman and Sellers used Canadarm2 to unberth the OBSS from the sill of Atlantis' cargo bay and handed it off to the shuttle's robotic arm, operated by Ham and Antonelli.[80] During EVA 2, commander Ken Ham provided photo and television support, and pilot Tony Antonelli served as the spacewalk choreographer.Earlier in the day, at 10:52 UTC, following leak checks, ISS Expedition 23 commander Oleg Kotov and flight engineer Alexander Skvortsov opened the hatch to the MRM-1 module.[85] The Canadarm2 was used to return the ICC-VLD to the bay, and was operated by Mission Specialists Piers Sellers and Garrett Reisman and space station flight engineer Tracy Caldwell Dyson.[89] The crew of Atlantis awoke on flight day 11, and after a couple of hours of personal time, began the late inspection of the shuttle's wing leading edges and nose cap.That complete, Ham and Antonelli fired each of the shuttle's 44 attitude control thrusters, which were designed to orient Atlantis in space as it descended from orbit and through the upper atmosphere.
