[00:01.100 --> 00:02.140]  Challenge 5
[00:03.280 --> 00:04.700]  Here's what we know.
[00:04.700 --> 00:08.700]  We've done our best work, and it seems that we've regained control of the satellite.
[00:08.860 --> 00:10.600]  But how do we know for sure?
[00:10.980 --> 00:17.600]  The challenge? Teams must prove that we are fully in control of the satellite system by successfully imaging the moon.
[00:17.700 --> 00:18.980]  Here's how they do it.
[00:18.980 --> 00:22.440]  By now, teams should have restored the command and data handling system,
[00:22.440 --> 00:26.040]  repaired the Attitude Determination and Control System, ADCS,
[00:26.040 --> 00:27.840]  and resumed payload operation.
[00:27.840 --> 00:29.800]  But their work is not done.
[00:29.800 --> 00:35.520]  They must now figure out the satellite's current orientation by sending commands to the command and data handling system,
[00:35.520 --> 00:38.700]  which will in turn provide essential readings back to the team
[00:38.700 --> 00:44.680]  and enable them to issue commands to point the satellite and imager payload at the moon using the ADCS.
[00:44.800 --> 00:47.260]  Once the imager payload is lined up to the moon,
[00:47.260 --> 00:51.780]  the next command will tell the imager to take a picture and save it onboard the satellite.
[00:51.780 --> 00:56.380]  The next time the satellite passes over a ground station, this image will be downloaded.
