Rover + Skycrane
The Rover + Skycrane is a stock craft consisting of an unmanned rover with a landing module on top of it.
Landing module
The landing module is propelled by 4 radially-mounted Rockomax 24-77 engines. Those are fuelled by one ROUND-8 Toroidal Fuel Tank and one Oscar-B Fuel Tank mounted on top of each other. Yet it doesn't have enough fuel onboard for landing the rover from orbit in most cases, but it can be used for the last meters. There is only fuel for 6.4 seconds on full thrust in a vacuum available.
The landing module has no separate command module aboard making it complicated to detach the rover and then discard the landing module.
Although it is named Skycrane it doesn't use the same technique to place the rover like the sky crane did with Curiosity. It is not possible in the stock game to have two parts only connected with a tether so that the landing module has to touch down with the rover.
Rover
The rover itself can be controlled by six RoveMax Model S2 wheels. It is equipped with various environmental sensors. There are eight OX-STAT Photovoltaic Panels placed on the top side tilted into all directions allowing sufficient electrical supply.
