VIPER reaches final tests as astronauts assess future lunar vehicles
NASA’s VIPER water-search rover is fully built and undergoing final testing in Houston, while astronauts have assessed mockups of future crew-carrying vehicles. The agency’s lunar mobility update distinguishes those completed evaluations from planned wheel tests and deliveries. It describes how lighting, terrain and energy use shape operations around the lunar south pole, ahead of VIPER’s targeted 2027 mission. The planned route covers about 30 km.

VIPER is undergoing final tests in Houston
NASA’s official lunar mobility update places VIPER, its rover for finding water and other volatile substances, at Houston’s Johnson Space Center for its last tests. The rover is fully built. NASA targets a 2027 mission near the lunar south pole. The plan calls for the Blue Moon Mark 1 lander to deliver it, followed by a journey of approximately 30 km. Teams at Ames Research Center, the planned operations base, are simulating possible mission scenarios.[1]
Astronauts assessed cabins while wearing spacesuits
Space companies Astrolab and Lunar Outpost are developing vehicles to carry astronauts. At Axiom Space, astronauts used spacesuit mockups to examine the cabin and display interfaces of a CLV-1 model delivered by Astrolab. At Johnson, Lunar Outpost supplied the third of its static Pegasus mockups. Wearing pressurized suits, astronauts examined the layout, ease of use and crew comfort. These evaluations examine how the vehicles accommodate people equipped for lunar surface work.[1]
Wheel tests will examine simulated lunar ground
Both companies plan wheel tests at Glenn Research Center using simulated lunar soil, followed by crew evaluations of drivable mockups. NASA identifies navigation, lighting and energy preservation as key operating issues. Entering and leaving shadowed ground changes the conditions in which the vehicles must function. The update describes completed mockup evaluations alongside future tests and delivery targets, with lunar crew transport still in development.[1]
