I've had issues with the main Lunascan computer rarely but it caused me to reboot during missions a few times with only a few minutes lost. The Lunascan Quad shows the session starting at about 19:35:00 (7:35 PM) with Camera 4 out.  I was scanning the Moon using the big 40" monitor and getting great images. At 19:43:21 the Graphics Computer on Cam, 3 position on the Quad dropped off. I was still scanning the Moon and knew it would end when the target entered the big tree south of me soon, so I kept imaging. Then I realized there was one thing I hadn't checked. The SSI camera scanning the Moon sends the signal through a USB line to the main computer, then through one of the two digital-to-analog converters that puts the 640x480 live images on the recorders. DVR2 is an aperture video device and is the first recorder to record the unredacted hi-res images, then feeds the signal to the Quad so it can be recorded again on the Cam 4 position. That screen (bottom right) was blue or blank. That told me that the pc was getting the images live but the DVR was not. Somehow the input selector had gone to L2 instead of the normal default of L1. As soon as I changed that, the images were on the Cam 4 position but by now the Moon was into the edge of the tree. All the live imaging I had seen and navigated through with my DOB Driver II hand control had NOT been recorded. At that point I pulled the mission.

But then I had to do a last minute routine check of the MADAR room and was supposed to reset the 1382, and found the system wasn't working. I then suspicioned a power failure or EMP of some kind. I tried several times to reboot the MADAR computer and it wouldn't go. I unplugged the pc and went upstairs. After a few chores/meds I was getting perturbed as we have had outages that knocked out everything before, even the surveillance recorder, clocks, tvs, etc. So when I checked the Radiation Computer and nothing was onscreen I wasn't surprised. So, in conclusion, something knocked out the Graphics Computer in the trailer at 7:35 PM and the MADAR monitor and the RA pc in the lab.


WWV great except when doors are closed. Work on exterior antenna.

LCD panel failure on  40” monitor. Proceed without it until a new one can be purchased.
