NASA’s Volatiles Investigating Polar Exploration Rover (VIPER), once canceled due to budget concerns, may still find its way to the Moon’s south pole—thanks to potential private-sector partnerships. The space agency announced on Feb. 3, 2024, that it is seeking proposals from U.S. companies to collaborate on deploying VIPER, a mission that could provide crucial insights into lunar water ice.
VIPER’s Original Mission and Cancellation
VIPER was designed as a scout rover, meant to search for water ice deposits near the Moon’s south pole. This effort aligns with NASA’s Artemis program, which aims to establish permanent lunar bases and use in-situ resources to sustain long-term human missions.
The $450 million mission was originally scheduled to launch aboard Astrobotic’s Griffin lander in 2024, under NASA’s Commercial Lunar Payload Services (CLPS) initiative. However, on July 17, 2024, NASA canceled the mission, citing the need to save approximately $84 million in development costs.
Less than a month later, on Aug. 9, 2024, NASA issued a request for information (RFI) to gauge private sector interest in repurposing VIPER. Now, this latest call for proposals represents a significant step forward in potentially reviving the mission.
A New Private-Public Partnership
NASA has outlined a clear role for its potential partner:
🔹 Provide a ride to the Moon – The selected company must arrange VIPER’s launch, integration, and landing on the lunar surface.
🔹 Execute a science and exploration campaign – The mission should conduct VIPER’s original water ice research as planned.
🔹 Disseminate scientific data – All VIPER-generated findings must be shared with the scientific community.
Importantly, NASA will provide VIPER as-is—companies cannot disassemble the rover or repurpose its instruments for other spacecraft.
“Moving forward with a VIPER partnership offers NASA a unique opportunity to engage with the private sector,” said Nicky Fox, associate administrator of NASA’s Science Mission Directorate. “This partnership could tell us more about water on the Moon while advancing commercial lunar landing capabilities.”
Why VIPER’s Mission Matters
VIPER’s mission remains critical to NASA’s long-term lunar exploration strategy. Understanding the distribution of lunar water ice is essential for:
✅ Identifying sustainable resources for astronaut survival (drinking water, oxygen production).
✅ Supporting in-situ resource utilization (ISRU) to produce rocket fuel for deep-space missions.
✅ Advancing commercial lunar activities, including future mining and infrastructure projects.
According to Joel Kearns, deputy associate administrator for exploration at NASA, the VIPER partnership would provide valuable opportunities for companies looking to expand their lunar surface operations.
“Being selected for the VIPER partnership would benefit any company interested in advancing their lunar landing and surface operations capabilities,” Kearns stated.
Next Steps: Proposals and Selection
NASA has set a Feb. 20 deadline for initial proposals from interested companies. After reviewing submissions, NASA will request detailed proposals from selected firms, with the goal of making a final decision this summer.
If successful, VIPER could become one of the first major private-public lunar exploration missions, demonstrating new pathways for collaboration between NASA and commercial space companies.
With water as the key resource of interest, VIPER’s resurrection could pave the way for the future of lunar exploration, resource utilization, and long-term space colonization. 🌕🚀
