Launch Day 8:45 PM

Checkout of the thrusters (by performing test firings) is complete. We've also done our first "wheel unload" (the reaction wheels' angular momentum has to be adjusted using the thrusters). No problems.

We have a mid-course correction (MCC) coming up tomorrow. My role in that is to convert the thruster calibration values and other burn-related parameters into a form that the onboard computer can "understand." I'll also support the testing of that, as well as the uplink to the orbiter (as we call LRO in everyday conversation). I'll be back here in the wee hours of the morning when we expect those input data to arrive.

I worked with one of my colleagues to create a very reliable and fast conversion process for the burn-related data. Tomorrow morning is its first use outside of simulations.
