High-Gain Antenna Test Continues

The SDO Team continues running the high-gain antenna (HGA) test. We are pretending that the “bottom” HGA has stopped working and we are running the spacecraft upside down to stay in contact with the ground. There has been no problem with the HGAs, but we need to keep the SDO Team thinking how to handle these problems before they happen.

As you can see in the picture, the FOT is using Camilla as a reminder what roll angle SDO is at. Currently at 153.7°, tomorrow SDO will roll to 180°. The test will end on April 25 at 1900 UTC (3 pm ET).

As the test progresses, the software to correct the orientation of the near-realtime images continues to be improved. By the end of the test all of the images will be correct!
