Griffin's flexible mounting options can accommodate a variety of rovers and other payloads to support robotic missions like skylight exploration, sample return, resource prospecting, and polar volatile characterization.

Griffin's autonomous landing uses cameras, IMUs, and LIDAR to safely touch down within 100 meters of any targeted site, even in rugged and hazardous terrain.

Griffin’s aluminum frame is stout, stiff, and simple for ease of payload integration. The main isogrid deck accommodates flexible payload mounting on a regular bolt pattern. A dedicated payload adapter and optional egress ramps can accommodate rovers and other large payloads. Four legs absorb shock and stabilize Griffin during touchdown.

Griffin uses a propulsion system featuring next generation space engine technology. Its seven main engines perform all of the spacecraft’s major maneuvers, including trans-lunar injection, trajectory correction, lunar orbit insertion, and powered descent. Four clusters of attitude control thrusters maintain lander orientation throughout the mission.

Griffin's communication system uses a high-powered, flight heritage transponder and a combination of low, medium, and high gain antennas for lander commanding and telemetry with Earth ground stations. This system also relays data between the payload customer and their payload throughout the mission. The lander-payload connection is provided via Serial RS-422 or SpaceWire for wired communications and an optional WLAN modem for wireless communications with deployed payloads such as rovers.

Griffin's power system uses a space-grade lithium-ion battery to store energy while a panel of triple junction solar cells generates power. Whenever possible, the solar panel is pointed towards the Sun to enable maximum power generation, while the battery is utilized for quick discharge activities and during mission phases when the solar panel is not generating power. Griffin provides a dedicated payload power bus to meet a wide range of payload requirements throughout the mission.

Guidance Navigation & Control

Griffin’s GNC system uses heritage algorithms enhanced by recent developments in machine vision navigation. During cruise and lunar orbit, off-the-shelf sensors and standard techniques – such as radio time-of-flight, Doppler tracking, sun sensors, a star tracker, and an inertial measurement unit – are used to determine the spacecraft’s position and attitude. During descent and landing, Doppler LiDAR and Astrobotic’s proprietary terrain relative navigation (TRN) are used. A scanning LiDAR can also be added to detect and avoid slopes, rocks, craters, and other hazards.
