Japan landed its Smart Lander for Investigating the Moon, or SLIM, craft on the floor of the moon on Jan. 20, 2024. Despite an influence problem 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 the earth to efficiently land on the moon. This is a big achievement and solidifies Japan’’ place as a frontrunner in area expertise.
While the craft landed successfully on the lunar surface and deployed its rovers, SLIM’s photo voltaic cells weren’t functioning correctly – which means that the craft might doubtless only operate for a few hours.
I’m a scholar of international affairs who research area. Like NASA and different area businesses, the Japan Aerospace Exploration Agency, or JAXA, needs to advance analysis and expertise by demonstrating new strategies and gathering scientific knowledge. The touchdown can also be part of one thing greater – a growing global interest in lunar activity.

Precision expertise
Japan’s achievement is not solely symbolic – Japan is demonstrating plenty of new applied sciences with the lander. The title, Smart Lander for Investigating the Moon, refers back to the spacecraft’s new precision-landing technology.
This expertise might help future landings by permitting spacecraft to land in comparatively small areas amid rocky or uneven terrain, relatively than having to seek out giant clearings. This capacity shall be significantly vital sooner or later as nations give attention to very particular areas of interest at the lunar south pole.
The lander additionally carried two small rovers, every of which can display a brand new expertise for transferring on the moon.
Lunar Excursion Vehicle 1 features a digital camera, in addition to scientific tools, and makes use of a hopping mechanism to maneuver on the moon.
Lunar Excursion Vehicle 2, developed in a partnership amongst authorities, trade, and academia, is a sphere sufficiently small to slot in the palm of your hand. Once on the floor, its two halves separate barely, permitting it to roll round.
SLIM was designed to land within 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 photographs of the lunar floor. Its system quickly in contrast these photographs to crater patterns on lunar maps that JAXA developed with knowledge from earlier missions.
As nations determine areas which might be probably to carry helpful assets, corresponding to water in the form of ice, precision touchdown expertise will permit businesses to keep away from close by hazards and attain these areas with out incident.
International relations again on Earth
There is a geopolitical factor 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. In addition to regional concerns, these accomplishments assist to ascertain nations as leaders on a worldwide scale – able to one thing that few nations have ever performed.
Japan’s launch comes solely six months after India’s moon landing and simply weeks after a failed attempt by a U.S. firm, Astrobotic.
Both Russia and the private company 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 world endeavor.
Despite latest setbacks, corresponding to NASA announcing delays to its subsequent Artemis mission, the U.S. continues to be a transparent chief in area and lunar exploration. NASA has multiple spacecraft orbiting the moon proper now, and it is already efficiently launched the SLS rocket, which is able to taking people again to the moon.
NASA is growing very giant and complicated programs internally – just like the Gateway space 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 currently – like within the Commercial Lunar Payload Services program that supported Astrobotic’s try. This is a brand new strategy that entails some danger, however offers the chance for industrial innovation and progress of the lunar economy whereas giving NASA the power to give attention to massive, complicated elements 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. This is a brand new and complicated expertise that shall be essential to human missions on the moon in coming years.
