Illustration of NASAs Volatiles Investigating Polar Exploration Rover (VIPER) on the lunar surface. This mobile robot will land at the South Pole of the Moon in late 2024 on a 100-day mission. It will provide critical information about the origin and distribution of water on the Moon and help determine how we can harvest the Moons resources for future human space exploration. About the size of a golf cart, the VIPER will roam several miles, using its three instruments and a 1-metre drill to sample various soil environments.
