Video title:  therefore as technically raised its Apogee even with all its perigee has fallen down so the highest point in the orbit is higher the lower lowest point on the orbit is lower but the average height is lower to do this the spacecraft has to maintain an attitude as to orient the sail when it's going in one direction so the receives the thrust from the Sun and then when it comes around and it doesn't want to experience drag it rotates the sail to be edge on the attitude control comes from a single reaction wheel so it can rotate the spacecraft in a single axis but it also has a set of magnet or cores and these provide controls and other axes but also more importantly when the reaction wheel starts to get saturated they are able to desaturate it and make and the mission they have apparently modified the software in the last few days because they were getting too much desaturation time so they claimed this may improve it in performance in coming weeks and this is an experimental spacecraft after all incidentally some of you might be wondering why an experimental crowdfunded satellite launched onboard an Air Force mission and the reason for this was the parent spacecraft in this case was procs one and that was an Air Force mission it's supposed to be a satellite inspector the idea was that this would demonstrate the capability to cool orbit and autonomously track another satellite and fly around and collect all sorts of information and to do that it would carry a CubeSat on board which would eject and then for a week we demonstrate these this coordinate flying and these your data gathering but somewhere along the way it lost this the project was d scope perhaps because it was too far behind schedule or other plans or a food I'm not really clear but the spacecraft essentially lost it said tracking mission it lost solar panels it lost his
