Nasa's Artemis Lunar Exploration Programme
Introduction
Nasa is considering a novel approach to enhance its Artemis lunar exploration programme by deploying a spare Mars rover, PROMISE, to the Moon.
PROMISE Overview
- PROMISE stands for Polar Rover for Observation, Mapping, and In-Situ Exploration.
- It was initially developed as a ground-based engineering model for the Curiosity and Perseverance Mars missions.
- The rover, previously known as OPTIMISM, was utilized to test updates and hardware fixes.
Proposed Mission
If approved, PROMISE would serve a dual purpose by conducting scientific work on the Moon and aiding in preparations for a sustainable human presence on the lunar surface.
Power System Advantage
- PROMISE is equipped with a radioisotope thermoelectric generator (RTG), providing an advantage over solar-powered rovers.
- The RTG allows for continuous operation, crucial for the moon's south pole conditions.
Strategic Importance
The lunar south pole is a critical area for exploration due to its potential water ice deposits, which could supply water, oxygen, and fuel for future missions.
Implementation Steps
- Minimal refurbishment is needed to adapt PROMISE for lunar operations.
- This initiative aligns with Nasa's phased approach to developing a permanent lunar outpost.
- The project is part of Nasa's Commercial Lunar Payload Services (CLPS) programme, with up to 20 missions planned through 2029.
Supporting Missions
Nasa has awarded contracts to Astrobotic, Firefly Aerospace, and Intuitive Machines for lunar landings, which will support scientific and technological progress on the Moon.
Conclusion
This proposal demonstrates Nasa's resourcefulness in repurposing existing technology to further lunar exploration, potentially making PROMISE one of the first nuclear-powered rovers on the Moon.
