Formation Re-Acquisition
After the AOK experiment, the two satellites have increased their distance up to some 60km. The formation is broken, and is to be reacquired under ground control. This activity has always been planned to be done manually as due to possible long distances (hundreds of kilometers), availability of the intersatellite link was not guaranteed, and therefore the satellites do not exchange GPS data.

Reports:

View of Tango from 41km

As Mango returns home from its solo experiment (AOK), GSOC is activating the VBS every now and then to take a look at the final destination: the Tango satellite. And it is a beautyfull view. The video below is taken from 41km, and the GPS navigation has in the mean time been activated. The intensity of the objects has been enhanced for better contrast. The VBS is observing the approach from the passenger seat, and is apparantly getting good lighting conditions. During the ARV experiment, the sun angle was such that 30km was the maximum distance for VBS observations, but here at 41km and at this time of the year, there is still a large part of navigation data to be collected. Mango is coming home!
