The article discusses NASA's consideration of repurposing a Mars rover replica, named PROMISE, for lunar missions.Originally designed as a Mars exploration vehicle, PROMISE is a modified version of the Perseverance rover, lacking its nuclear power source (RTG) and scientific instruments.The project faces significant challenges, including securing a可用 RTG, as all current ones are reserved for other missions.

The rover would need modifications to adapt its instruments for lunar conditions, such as deeper drilling tools and spectrometers for volatile detection.While the idea could enhance lunar exploration by enabling extensive surface mapping, funding and technical hurdles remain.

The article also mentions recent CLPS program contracts with companies like Astrobotic and Intuitive Machines, which will deploy lunar modules with NASA instruments.However, the feasibility of PROMISE's mission is uncertain due to budget constraints and the lack of a suitable lander for its deployment.Critics argue that the proposal reflects NASA's struggles to advance lunar projects amid competing priorities and geopolitical pressures.
