NASA is sending a mobile robot to the south pole of the Moon to get a close-up view of the location and concentration of water ice in the region and for the first time ever, actually sample the water ice at the same pole where the first woman and next man will land in 2024 under the Artemis program. About the size of a golf cart, the Volatiles Investigating Polar Exploration Rover, or VIPER, will roam several miles, using its four science instruments — including a 1-meter drill — to sample various soil environments. Planned for delivery in December 2022, VIPER will collect about 100 days of data that will be used to inform development of the first global water resource maps of the Moon.

An Engineer maps out the position of rocks during VIPER testing at The NASA Glenn Research Center. A test version of the VIPER rover continues to show how well it moves through a simulated lunar surface in our SLOPE lab. This is a critical step toward ensuring the rover is ready for its 2023 mission to find water ice at the Moon’s South pole.

Virtual Intelligent Planetary Exploration Rover, VIPER Mobility Platform Testing  An engineering model of the Volatiles Investigating Polar Exploration Rover, or VIPER, is tested in the Simulated Lunar Operations Laboratory at NASA’s Glenn Research Center in Cleveland, Ohio. About the size of a golf cart, VIPER is a mobile robot that will roam around the Moon’s South Pole looking for water ice in the region and for the first time ever, actually sample the water ice at the same pole where the first woman and next man will land in 2024 under the Artemis program.  The large, adjustable soil bin contains lunar simulant and allows engineers to mimic the Moon’s terrain. Engineers from NASA’s Johnson Space Center in Houston, where the rover was designed and built, joined the Glenn team to complete the tests. Test data will be used to evaluate the traction of the vehicle and wheels, determine the power requirements for a variety of maneuvers and compare methods of traversing steep slopes. Respirators are worn by researchers to protect against the airborne silica that is present during testing.    VIPER is a collaboration within and beyond the agency. NASA's Ames Research Center in Silicon Valley is managing the project, leading the mission’s science, systems engineering, real-time rover surface operations and software. The rover’s instruments are provided by Ames, NASA’s Kennedy Space Center in Florida and commercial partner, Honeybee Robotics in California. The spacecraft, lander and launch vehicle that will deliver VIPER to the surface of the Moon will be provided through NASA’s Commercial Lunar Payload Services program, delivering science and technology payloads to and near the Moon.

Technicians prepare the Mass Spectrometer Observing Lunar Operations (MSolo) for NASA’s Volatile Investigating Polar Exploration Rover (VIPER) mission for packing inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. MSolo will be shipped to Johnson Space Center in Houston for integration into VIPER. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface. MSolo will be part of NASA’s first Commercial Lunar Payload Delivery Service (CLPS) mission where under the Artemis program, commercial deliveries will be used to perform science experiments, test technologies, and demonstrate capabilities to help NASA explore the Moon and prepare for human missions. VIPER is scheduled to be delivered to the Moon’s South Pole in late 2024 by Astrobotic’s Griffin lander as part of the CLPS initiative.
