This blog follows the progress of the LRO mission through Integration and Testing at NASA's Goddard Space Flight Center and launch site processing at KSC\Astrotech. Its purpose is to enable communication to the entire LRO Team about the status of ongoing activities.

LRO was launched June 18th, 2009 at 5:32pm EDT from KSC. This BLOG will follow the progress of the mission as LRO travels to the Moon and establishes orbit around it.

This BLOG will be periodically updated during LRO's early mission but as the nominal mission unfolds the official NASA LRO website and the LRO Science Instrument's own websites will evolve into a more interesting sources of LRO science results as postings appear there first and LRO engineering and operations (source of this site) will become increasingly routine.

Notable changes to the MR1 SER:

Step 37 of Pre-Simulation Preparation: delete the text that is there, and replace with, "I&T TC should start gssas_fixcurrall(4.3) to set the SAS current to 4.3 A per segment."
After step 39, insert "After balance of the SAS gimbal is achieved, as declared by the thermal engineer, the I&T TC should start gssas_fixcurrall(3.8) to set the SAS current to 3.8 A per segment, then start the SAS Background Cycling Procedure with time coordinated with the MOC
a. PAGE GS_SAS_ORBIT_SIM
b. Enter 48 minutes for eclipse duration"

The other balance that needs to be achieved during this transition is the LOLA hot-operational balance. For this balance point, we need the LOLA laser firing. We plan to submit an Operations Activity Request to the MOC during the simulation to achieve this configuration change and exercise the MOT a bit. We do not want to start out immediately with the laser firing, in order to save shots.

Call Dave's cell if you have any questions.
