The Japan Aerospace Exploration Agency (JAXA) simply confirmed its small car-sized Smart Lander for Investigating Moon (SLIM) craft efficiently arrived close to the Shioli crater and has safely ejected its two small onboard robots. The historic achievement marks Japan’s first lunar landing, and makes it the fifth nation to ever attain the moon’s floor. According to JAXA officers, nevertheless, the SLIM’s “Moon Sniper” just isn’t with out problems.
“It seems the solar cell is not generating electricity at this point in time,” JAXA’s president Yamakawa Hiroshi stated throughout a Friday morning information convention. As such, it’s at present working on battery energy that’s solely anticipated to final “several hours.”
“We are trying to maximize the scientific achievement,” Hiroshi continued, in line with livestream translation from Japanese to English.

When requested if the mission is successful or failure, JAXA officers defined they take into account gentle landing itself profitable, and that “most of the equipment is functional.” Engineers take into account the photo voltaic cell downside a “separate issue,” and that SLIM continues to be sending and receiving knowledge, together with photos, again to Earth.
SLIM launched to Earth orbit alongside an X-ray telescope on September 6, 2023. After a number of weeks’ of diagnostic checks and observations from JAXA engineers, SLIM initiated an engine burn to go away Earth orbit on September 30, the place it then start its multi-day journey in direction of the moon. The craft maintained an orbit across the moon since October 4, and commenced landing procedures on January 19 at roughly 10:20am EST.
Friday’s achievement breaks a world streak of current lunar mission failures. Less than 24 hours earlier than SLIM’s gentle landing, Astrobotic’s Peregrine spacecraft, initially destined for the moon, burned up upon reentry into Earth’s environment. Peregrine efficiently launched on January 8 from Cape Canaveral, FL, however quickly suffered a “critical loss of propellant” that ensured it could not attain its meant vacation spot. In April 2023, the Japanese firm ispace’s Hakuto-R achieved a lunar orbit, however crashed throughout its landing try.
Even if SLIM’s photo voltaic cell points vastly shorten its lifespan, affirmation of its meant precision landing would mark a significant second for Japan’s house program. JAXA representatives estimate it may take roughly a month earlier than realizing whether or not or not SLIM landed inside 100-meters of its meant web site. Officials, nevertheless, already expressed optimism concerning the achievement throughout Friday’s livestream.
“It used to be landing where we could, now we can land where we want,” stated one JAXA consultant.
