- DPR initialized in "Service Mirror" mode. Removed flag and blew out sensor with canned air. Fixed Service Mirror but still stuck in "Rebalance" mode. Informed Project Manager. DPL and VXL good. Will try cycling DPR in the air.
- Tested RICE on the ground. Fully operational.
1226 - Cycled power on DPR to see if mirror is dry enough to attain dew point. Successful.
1247 - All 3 cloud physics probes functioning and displaying images/histogram.
1419 - Lost SATCOM to the ground. Every item on the status page went RED. Data still being reported on Aeros...
1425 - Cycled power on Router. Items on status page going back to green.
1429 - SATCOM to ground returned.
*ACSERVER NOT RETURNING TO GREEN ON STATUS PAGE
Chris W. helped to fix via several terminal commands.
1440 - Entire status page green again.
RICE is noisy for entirety of flight.
1618 - Stuart B. asked that the camera process be stopped so he could make an update to the down-looking camera.
1619 - Restarted cameras. Everything still functioning properly.
1729 - Lost VCSEL on descent. Likely iced up the lenses flying through cloud. Cycled VCSEL but did not come back. Very close to landing.
2D Probe End Diode Voltages very unstable prior to landing. Again, likely flying through cloud and getting cold-soaked.
