on orbit. Engineers also noted MRM-1 cycled its Fire and Smoke detector self test several times. 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. An agency-wide Flight Readiness Review (FRR) was held at KSC in Florida on May 5, 2010, to discuss Atlantis launch preparations. At the end of the review, top NASA managers made the decision to officially set the launch for May 14, 2010, at 14:20 EDT. NASA held a post news conference to brief about the results of the FRR. The briefing was broadcast on NASA TV and was attended by NASA's Associate Administrator for Space Operations, William Gerstenmaier, Space Shuttle Program Manager John Shannon and Space Shuttle Launch Director, Michael Leinbach. Shannon mentioned that, firstly, ceramic inserts around Atlantis' windows and forward rocket pod were tested after an insert loosened during Discovery's re-entry on STS-131, posing a potential impact threat. The inserts had been re-installed on to Atlantis using a thicker braided cord to reduce the chances of a backing out. Secondly, it was mentioned that engineers had reviewed work to confirm that all systems on Atlantis' Ku band antenna were in place. The testing had been provoked after the failure of that communication system during STS-131. Mr. Leinbach also acknowledged the skills and experience of the engineering teams and thanked the engineers who had successfully resolved hypergolic loading issues. Hypergolics are chemicals that ignite when they come in contact with each other. The propellants are used in the reaction control system that steers the shuttle in space. A booster rocket segment that had first flown 25 years before on Atlantis' maiden flight (STS-51-J) was used to help fly STS-132. The aft dome on the left solid rocket booster that lifted off to support Atlantis' STS-132 mission first launched STS-51-J on October 3, 1985. Including STS-132, 18 of Atlantis' 32 flights were represented by the boosters' segments. Launch preparations Atlantis''' astronauts traveled from Johnson Space Center, Houston to the KSC launch site on May 10, 2010, to prepare for the launch. The crew, arriving in four Northrop T-38 Talon jets, landed on the Shuttle Landing Facility around 18:49 EDT. The official countdown to liftoff started on May 11, 2010, after the countdown clocks at KSC were activated at 16:00 EDT, ticking backward
