NASA Advances VIPER Lunar Rover with Earth-Based Tests

NASA is evaluating the future of its VIPER lunar rover mission, which was canceled in July due to anticipated cost overruns and delays. The agency is reviewing responses to a request for information (RFI) seeking alternative uses for the nearly complete rover. Despite successful environmental tests, VIPER's launch was delayed to no earlier than September 2025 on Astrobotic's Griffin lander. NASA is considering partnerships and may propose next steps by early 2025, while Congress could potentially intervene to revive the mission.
