The already-built rover could now be scrapped for parts.

NASA has terminated an ambitious mission intended to map ice and then drill into it at the Moon’s south pole. The space agency announced the cancellation of the Volatiles Investigating Polar Exploration Rover (VIPER) yesterday, citing budget woes, rising costs and several delays in construction on the rover and its lander. Now, it is seeking partners interested in using the rover — which is already assembled — or components of it, for future lunar missions.

The agency has already sunk US$450 million into building VIPER, and reports that it would need to spend millions more to complete testing. This would threaten funding for other launches it is planning as part of its Commercial Lunar Payload Services (CLPS) programme, in which the agency partners with private US aerospace companies to transport scientific instruments to the lunar surface. Before the mission delays, VIPER was intended to be the first-ever mission to scout for ice on the ground at the Moon’s south pole.

“This has been a really tough decision, which we make in an uncertain budget environment,” said Nicola Fox, associate administrator for NASA’s science mission directorate when announcing the cancellation. “But we do believe that this is a way for us to continue to support the entire CLPS portfolio.” The US Congress reduced NASA’s budget for 2024 compared with 2023, and the budget proposed for 2025 by the US House of Representatives is only about a 1% increase from this year, which is lower than the current rate of inflation.
