Japan’s SLIM lunar touchdown highlights its superior area know-how and international management in area exploration, regardless of challenges, enhancing its place in worldwide lunar analysis and collaboration.

Japan landed its Good Lander for Investigating the Moon, or SLIM, craft on the floor of the Moon on January 20, 2024. Regardless of an influence subject with the lander, the occasion holds each political and technical significance. It’s Japan’s first lunar touchdown – making it solely the fifth nation on this planet to efficiently land on the Moon. It is a vital achievement and solidifies Japan’s place as a pacesetter in area know-how.

Whereas the craft landed efficiently on the lunar floor and deployed its rovers, SLIM’s photo voltaic cells weren’t functioning correctly – which means that the craft might doubtless solely function for a couple of hours.

I’m a scholar of worldwide affairs who research area. Like NASA and different area businesses, the Japan Aerospace Exploration Company, or JAXA, desires to advance analysis and know-how by demonstrating new strategies and accumulating scientific information. The touchdown can also be part of one thing greater – a rising international curiosity in lunar exercise.

Precision know-how

Japan’s achievement isn’t solely symbolic – Japan is demonstrating plenty of new applied sciences with the lander. The title, Good Lander for Investigating the Moon, refers back to the spacecraft’s new precision-landing know-how.

This know-how might help future landings by permitting spacecraft to land in comparatively small areas amid rocky or uneven terrain, somewhat than having to seek out giant clearings. This skill might be notably essential sooner or later as nations concentrate on very particular areas of curiosity on the lunar south pole.


SLIM’s touchdown know-how allowed it to detect and keep away from potential obstacles.

The lander additionally carried two small rovers, every of which can show a brand new know-how for shifting on the Moon.

Lunar Tour Automobile 1 features a digicam, in addition to scientific tools, and makes use of a hopping mechanism to maneuver on the Moon.

Lunar Tour Automobile 2, developed in a partnership amongst authorities, business, and academia, is a sphere sufficiently small to slot in the palm of your hand. As soon as on the floor, its two halves separate barely, permitting it to roll round.

SLIM is designed to land inside a 328-foot (100-meter) zone, far smaller than earlier lunar landers which have had touchdown zones spanning a number of kilometers.

SLIM used a vision-based navigation system that took photos of the lunar floor. Its system quickly in contrast these photos to crater patterns on lunar maps that JAXA developed with information from earlier missions.

As nations determine areas which can be almost definitely to carry helpful assets, similar to water within the type of ice, precision touchdown know-how will enable businesses to keep away from close by hazards and attain these areas with out incident.

XRISM Launch

Worldwide relations again on Earth

There’s a geopolitical ingredient to those actions. China, India and Japan – the three nations which have efficiently landed on the Moon since 2000 – have interaction in regional competitors throughout plenty of areas, together with area. Along with regional concerns, these accomplishments assist to ascertain nations as leaders on a worldwide scale – able to one thing that few nations have ever carried out.

Japan’s launch comes solely six months after India’s Moon touchdown and simply weeks after a failed try by a U.S. firm, Astrobotic.

Each Russia and the non-public firm iSpace made unsuccessful touchdown makes an attempt in 2023. Japan’s success in touchdown on the Moon – even with photo voltaic panel points shortening the timeline for the mission – demonstrates that JAXA is a significant participant on this international endeavor.

Regardless of latest setbacks, similar to NASA asserting delays to its subsequent Artemis mission, the U.S. continues to be a transparent chief in area and lunar exploration. NASA has a number of spacecraft orbiting the Moon proper now, and it’s already efficiently launched the SLS rocket, which is able to taking people again to the Moon.

NASA is growing very giant and complicated methods internally – just like the Gateway area station, deliberate to orbit close to the Moon, and the infrastructure for the Artemis human Moon missions. It’s not unusual for these giant and complicated efforts to expertise some delays.

NASA has additionally turned many smaller-scale efforts over to industrial entities these days – like within the Industrial Lunar Payload Providers program that supported Astrobotic’s try. It is a new strategy that entails some threat, however supplies the chance for industrial innovation and development of the lunar financial system whereas giving NASA the flexibility to concentrate on massive, advanced points of the mission.

With regard to the Moon, JAXA has partnered with the U.S. and brought on an important element of the Artemis missions – the event of a pressurized lunar rover. It is a new and complicated know-how that might be crucial to human missions on the Moon within the coming years.
