VIPER (Volatiles Investigating Polar Exploration Rover) is a lunar rover developed by NASA (Ames Research Center), and currently planned to be delivered to the surface of the Moon in November 2024. The rover will be tasked with prospecting for lunar resources in permanently shadowed areas in the lunar south pole region, especially by mapping the distribution and concentration of water ice. The mission builds on a previous NASA rover concept called Resource Prospector, which was cancelled in 2018.

The VIPER rover, currently in development, will have a size similar to a golf cart (around 1.4 × 1.4 × 2 m), and will be tasked with prospecting for lunar resources, especially for water ice, mapping its distribution, and measuring its depth and purity. The water distribution and form must be better understood before it can be evaluated as a potential resource within any evolvable lunar or Mars campaign.

The VIPER rover is part of the Lunar Discovery and Exploration Program managed by the Science Mission Directorate at NASA Headquarters, and it is meant to support the crewed Artemis program. NASA’s Ames Research Center is managing the rover project. The hardware for the rover is being designed by the Johnson Space Center, while the instruments are provided by Ames, Kennedy, and Honeybee Robotics. The project manager is Daniel Andrews, and the project scientist is Anthony Colaprete, who is implementing the technology developed for the now cancelled Resource Prospector rover. The estimated cost of the mission is US$250 million in October 2019. NASA said on 3 March 2021 that the new lifecycle cost for the mission is US$433.5 million.

The VIPER rover will operate on the western edge of Nobile crater on Mons Mouton in the Moon’s south pole region. It is planned to rove several kilometers, collecting data on different kinds of soil environments affected by light and temperature — those in complete darkness, occasional light and in constant sunlight. Once it enters a permanently shadowed location, it will operate on battery power alone and will not be able to recharge them until it drives to a sunlit area. Its total operation time will be 100 Earth days.

Both the launcher and the lander to be used are competitively provided through Commercial Lunar Payload Services (CLPS) contractors, with Astrobotic delivering the Griffin lander and SpaceX providing the Falcon Heavy launch vehicle. NASA is aiming to land the rover in November 2024.
