Vyacheslav exposed the docking port. Using a combination of taps on New Caird ’s thrusters, some pushing and pulling by the robots, and Vyacheslav simply grabbing the spacecraft and nudging it this way and that, they inserted her "front door" docking port into the little crater that Vyacheslav and the robots had excavated, and mated it with that of Ymir ’s buried command module.
