Okay, this is my question. I successfully brought an MPLM to ISS within a shuttle's cargo bay, grappled it with the Arm,
moved to the ISS's docking port in correct orientation and docked it. Then the time for a back trip came, and I'm
confused - how do I put the thing back into the trunk? I can grapple it, move avay from the docking port, hit
undocking button, even place it over the shuttle's bay - but when I release the grapple, MPLM just slowly floats
away.
There are no placement markers. Is it possible at all to reattach an attachment without leaving Orbiter?
Maybe I should try harder?
