Today's Burn


Nearing today's orbit-adjustment burn, set for 8:25 AM EDT. Tomorrow morning will be the final one to get us into the commissioning orbit.
Around 6 this morning we did a reaction wheel momentum unload (entering "Delta-H Mode"), using thrusters to slow down the wheel speeds to keep them below specified thresholds.
Our colleagues at Arizona State University (home of the science operations center for the LRO Camera (LROC)) have posted a diagram showing where LRO is:
I've had some trouble on my home computer with it not showing the LRO path or position, but it displays fine on my work computer.
The projection of the lunar surface may be confusing to most readers. The far left and far right three-grid-wide segments are the far side (never seen from Earth) and the center six-square-wide segment is the near side, distinctive for its maria (the dark lava-bed plains, mostly absent from the far side). North is up.
Just a moment ago we reacquired contact with the Orbiter. This was my first shift during which the Orbiter passed behind the Moon. It emerged about 20 minutes later.
