being tracked from the ground, to better predict the movement and decay of objects in orbit. ANDE-2 consists of two spherical microsatellites, ANDE Active spacecraft (Castor) and the ANDE Passive spacecraft (Pollux), and will be tracked by the International Laser Ranging Service (ILRS) network as well as the Space Surveillance Network (SSN). One of the satellites, Pollux, is running Arduino libraries, with its payload programmed and built by students. A set of experiments to be deployed on the ISS were carried by STS-127, including Dosimetry for Biological Experiments in Space (ESA), Validation of Procedures for Monitoring Crew Member Immune Function, the student-made Image Reversal in Space (CSA/ISU), Nutritional Status Assessment (NASA), NASA Biological Specimen Repository and Tomatosphere-II (CSA). The STS-127 Official Flight Kit (OFK) included water samples from each of the five Great Lakes, a resin statue of a water droplet for the One Drop Foundation, and a copy of Beethoven's Fifth Symphony for the Montreal Symphony Orchestra, among other mementos. The docking module was also mounted with the DragonEye 3D Flash LIDAR ranging system manufactured by Advanced Scientific Concepts, Inc. The module was launched to test the docking system which will be used by the commercial SpaceX Dragon re-usable cargo carrier to send supplies to the ISS during the post-shuttle era. The Dragon spacecraft made its successful maiden flight in December 2010. Mission milestones The mission marked: 158th NASA crewed space flight 128th Space Shuttle mission 127th shuttle mission since STS-1 23rd flight of Space Shuttle Endeavour 29th shuttle mission to the ISS 102nd post-Challenger mission 14th post-Columbia mission 1st time that two Canadians have been in space at the same moment Shuttle processing Endeavour served as the STS-400 rescue vehicle for STS-125, and was prepared for a possible liftoff from Launch Pad 39B on May 15, 2009, four days after the launch of STS-125. After Atlantis performed the late inspection and was cleared for re-entry, Endeavour was officially released from stand-by status on May 21, 2009, and preparations for STS-127 were initiated. Endeavour moved from Launch Pad 39B to 39A on May 31, 2009, in preparation for STS-127. The crew of STS-127 arrived at Kennedy Space Center on June 2, 2009, for the Terminal Countdown Demonstration Test (TCDT) that concluded with a full launch dress rehearsal. The Flight Readiness Review (FRR), a meeting during which NASA managers assess mission preparations and officially set the launch date, concluded on
