English: Heavy, pressurized lunar rover intended to enable up to four crew to rove for two weeks on the Moon's surface. A crew airlock permits crew to exit and enter the rover and may double as a docking adapter to the Moon base. A smaller sample lock permits retrieval of lunar samples using remote manipulators mounted on the rover front. A cupola on top, similar to the cupola on the International Space Station, is a secondary driving station and permits views of the lunar terrain 360 degrees around the horizon and to much greater distances than the lower driving station.
