Mission Control remotely pilots the Advanced Duna Lander as it completes it’s final manuevers to dock with Duna Spaceport!
First, it circularizes it’s orbit…
…then rendezvouses with the Spaceport!
Next, it docks, backwards, with Duna Spaceport! This is so the crew of Explorer 7 can unload all the ground science experiment cargo that the lander carried with it!
Docking is a success! Duna Spaceport, and the new Advanced Duna Lander, wait for Explorer 7!
