astronauts, who are generally in a day-and-night pattern that is not equal to that of the launch site. The first flight day is the day of launch for the astronauts. That day started at the launch site on March 10, 2008 (local time), with the actual launch in the early hours of the 11th and the astronauts going to bed several hours after launch. March 10, 2008, is called flight day 1 by NASA, even though the actual mission launched on March 11. March 11 (Flight day 1, Launch) Endeavour launched on time at 02:28:14 EDT (06:28:14 UTC) early into the night of March 11, 2008, from Launch Complex 39A at the Kennedy Space Center. The Flash Evaporator System switched from its primary controller to the backup controller during launch, and instrumentation for a few left-side control thrusters was lost due to a card failure. These anomalies were not expected to affect the mission. March 12 (Flight day 2) The shuttle closed in on the space station. The crew used a 50 ft (15 m) laser-tipped boom to inspect its wings and nose for any sign of launch damage. The inspection has been standard procedure ever since the 2003 Columbia disaster. Flight director Mike Moses said a quick look at the images the astronauts beamed down to Earth revealed no signs of trouble. In addition to performing the inspection, the astronauts also prepared their spacesuits for the five planned spacewalks and gathered the tools they would need for the docking. March 13 (Flight day 3) Endeavour's commander, Dominic Gorie, guided the shuttle through a 360-degree backflip, known as the rendezvous pitch maneuver, to allow for full photographic surveillance of the thermal tiles on the Space Shuttle's underside before docking with the space station. Docking occurred at 03:49 UTC and the hatches between the two spacecraft were opened at 05:36 UTC on. After docking the pallet carrying Dextre was moved to the Payload ORU Accommodation (POA) of the Mobile Base Station (MBS) by Canadarm2. March 14 (Flight day 4) Spacewalkers Richard Linnehan and Garrett Reisman worked on installing Dextre. However, the Spacelab pallet carrying the SPDM would not power up. Engineers on the ground tried a software patch, though later suspected a design flaw in Dextres temporary power cable caused the issue. Crew members on board Endeavour used a robotic arm to remove the Japanese Logistics Module – Pressurized Section (JLP)
