Scheduled departure 1st shift Sunday,\u2019 noted USA information. \u2018Scheduled arrival at KSC 1st shift Monday.\u2019<\/p>\n The duo eventually took off at 9am Eastern, heading to Texas for a fuel stop.<\/p>\n Atlantis was originally set to leave on Friday<\/font>, but issues with the retraction of Atlantis\u2019 landing gear hydraulics and a damaged left hand \u2018salad bowl\u2019 joint delayed the continuation of mating operations by 24 hours, before the extra wait until Sunday. These issues were classed as resolved in later information.<\/p>\n Live coverage of the SCA\/Atlantis duo\u2019s taxi and take-off will be shown on NASA TV and covered as a live event on this site<\/font>.<\/p>\n Meanwhile, on the ISS, Expedition 15 commander Fyodor Yurchikhin and engineer Oleg Kotov have been carrying out instructions by Russian engineers on the ground, as they try to find out what caused the computer malfunctions during STS-117<\/font>. <\/p>\n So far a root cause has not been found, although the Russians believe they are starting to isolate the issue to computer circuitry resistance (impedance) \u2013 which is the focus of their current troubleshooting. <\/p>\n \u2018Yurchikhin and Kotov, with ground support, continued the extensive troubleshooting of the TVM (Terminal) and TsVM (Central) computers of the RS (Russian Segment),\u2019 noted a latest On Orbit Status report. <\/p>\n \u2018They focused on the cables in the SM associated with the TVM\/TsVM operation, testing their shielding capability both for the \u2018Start\u2019 and \u2018Stop\u2019 circuits, and on the connectors in the associated multi-contact sockets for TVM1, TVM3, TsVM2 and TsVM3, using resistance (impedance) measurements to look for disconnected connectors. <\/p>\n \u2018Yesterday\u2019s resistance\/continuity tests on the TVM2 data processing lane\u2019s \u2018start\/stop\u2019 control circuitry had indicated all measurements to be nominal except those across the contacts of the \u2018stop\u2019 relays which should have indicated completely open but showed partially closed contacts on at least two \u2018stop\u2019 relays. <\/p>\n \u2018This could be a possible explanation of the failure of the TVM2 start-up attempt on 6\/21.
