being "prox ops" reasonably fast.
Great, succinct info - MANY thanks!
Hmm. This is a bit of a brain teaser...
So if the satellite is deployed towards the rear of the ISS, it's velocity
will be slightly lower.
So does that mean it will go to a lower orbit- (Same as firing retros to
If so, then I believe as the orbit altitude is reduced, the apparent
velocity increases.....(??) which will cause ARISsat-1 to 'move ahead' of the
ISS over a few hours
But didn't we say the velocity would be less than the ISS due to the method
of deploying it against the velocity vector ?
Time for me to have a Tuna sandwich. We all know it's probably full of
Dolphin...and they are really clever.
