Our last DSN coverage is scheduled for this Sunday. We have switched our commanding strategy for our last 4 uplink opportunities. Instead of sending the SCP resets, we are sending commands to swap TWTAs. These are commands we have sent before, but not with the long sweeps we are now using. The SCP resets were sent over 200 times since 12/18/06. If the spacecraft powered up and was in SMode, there is a case where the TWTA may be a dead, yet the software thinks it is still okay. Yes, this is a real long shot - but the only thing left we could think of. So, the TWTA swap commands will be the last thing radiated to the spacecraft. The Plans & Status meetings will continue for the next several weeks on Mondays and Thursdays at 09:15 MST. We will use the meetings to provide updates on any reviews and closeout activities. MRO continues to look for MGS with their Star Tracker. The background sequence that went active on Wednesday (1/24) contains commands to "look" for MGS every 40 hours with the Star Tracker. This will continue through 2/2/07. We continue to prepare packages for the upcoming reviews. Thanks go to a lot of folks who have supported the anomaly recovery efforts. None of us wants to give up, yet it appears the time has come. - Kyle Kyle Martin Mission Ops System/RTO Team Chief Lockheed Martin Space Exploration Systems 303-977-6871 work 720-521-7535 pager kyle.w.martin@lmco.com
