NOTE: Please review the action groups below. There will be three separate Control From Here commands preprogrammed for each phase of the mission. These will ensure the proper navball alignment for various maneuvers and/or SAS modes.

The ER-4 was the first rover designed to explore another planet. The ‘Mole’ is unmanned, controlled remotely from Mission Control while it conducts scientific surveys and ground exploration. The ER-4 has a full compliment of ground and atmospheric sensors, but is limited to operation during the day due to it’s reliance on solar power. The ER-4 is dropped to the Duna surface via a radically-designed rocket-powered Skycrane after it’s aeroshell is jettisoned.
