NASA Reveals PROMISE Moon Rover to Hunt for Water Ice
NASA is building a new nuclear-powered lunar rover named PROMISE using recycled Mars robot parts to hunt for ice at the Moon's South Pole.
Space scientists in Cape Canaveral, Florida, have shared thrilling news about an adventurous robot ready to explore deep space. The United States space agency NASA announced it is advancing the development of the NASA PROMISE moon rover, a six-wheeled robotic explorer scheduled to blast off in late 2028.
This brave explorer has an exciting mission: hunting for hidden water ice at the Moon’s South Pole. Managed and built by NASA’s Jet Propulsion Laboratory (JPL) in Southern California, the rover will travel straight into some of the coldest, darkest places in our solar system.
What happened?
The name PROMISE stands for Polar Rover for Observation, Mapping, and In-Situ Exploration. Unlike typical moon vehicles that depend on sunlight, this rover will run on a nuclear battery known as a multi-mission radioisotope thermoelectric generator, or MMRTG. This clever device converts natural heat directly into electricity.
Why does a moon rover need nuclear power? A single lunar night lasts for two whole weeks on Earth, plunging the Moon into extreme, freezing cold. Furthermore, deep craters at the South Pole lie in permanent shadow where sunlight never falls. While solar panels would run out of energy and freeze, the nuclear power source will keep the rover warm and running through an 18-month primary mission.
Building a brand-new space rover can take huge amounts of time, but engineers came up with a smart solution. They are constructing PROMISE using spare flight hardware and engineering test components originally made for the Curiosity and Perseverance Mars rovers. Reusing these leftover parts saves both valuable time and money.
Once it lands, PROMISE will use a specialised robotic drill to dig about 3 feet (1 metre) beneath the surface into powdery lunar regolith. It also carries visible-light cameras, spectrometers to study rock minerals, temperature and radiation sensors, and high-performance space computing systems. To deliver the machine to the Moon, NASA awarded commercial aerospace company Blue Origin a base contract worth $94 million to carry and land PROMISE using its Blue Moon Mark 1 lander.
Why does it matter to you?
Have you ever reused leftover cardboard, bottles, or craft supplies to make a brilliant school project? NASA is doing something very similar by recycling spare components from famous Mars rovers to build an entirely new lunar explorer!
Finding water ice on the Moon is also a huge step forward for humanity. In the future, lunar ice could be turned into drinking water for astronauts or transformed into fuel for rockets. This means students in India today might grow up to see humans living and working on a permanent lunar base.
Words to know
- Regolith: The layer of loose dust, soil, and broken rock covering the solid surface of the Moon.
- Spectrometer: A special scientific tool that analyses light to find out what minerals or chemicals are inside an object.
- MMRTG: A multi-mission radioisotope thermoelectric generator, which is a power unit that turns heat into electricity.
- In-situ: A Latin phrase used by scientists that means examining something right where it is naturally found.
Did you know?
Because the Sun stays very low on the horizon near the Moon’s South Pole, deep crater rims block all sunlight, leaving the crater floors completely dark for billions of years!
Think about it
If you were asked to design an explorer robot using recycled materials from home or school, what parts would you use? What secrets would you want your machine to uncover on the Moon?
