The SDO Flight Operations Team supported a nominal lunar transit on Tuesday, May 3.

The FOT supported momentum unload maneuver (delta-H) #5 on May 4 at 1800 UT. The delta-H burn time was 3.8 seconds. Thruster 6 was fired for 150 milliseconds one minute prior to the delta-H burn in order to help prevent iron nitrate buildup in the fuel line. Momentum unload maneuvers are used to change the speed of the reaction wheels used to control where SDO is pointed.
