In a significant leap for space exploration, Japan has joined the exclusive club of nations achieving a soft lunar landing. The Japan Aerospace Exploration Agency (JAXA) successfully executed the landing of its Smart Lander for Investigating Moon (SLIM), affectionately dubbed the "Moon Sniper." However, a hiccup emerged as the spacecraft encountered a solar battery problem, causing it to rapidly deplete its power reserves.
Following a nerve-wracking 20-minute descent, JAXA announced that SLIM had safely touched down on the lunar surface, establishing communication. Despite this success, the impending issue with the solar cells loomed large, limiting the craft's operational time to just "several hours," according to Hitoshi Kuninaka, a JAXA official.
SLIM is part of the wave of new lunar missions initiated by both governments and private enterprises, marking the 50th anniversary of the first human moon landing. While crash landings and communication glitches are common hurdles, Japan now stands alongside the United States, the Soviet Union, China, and India as the fifth country to reach the Moon.
Mission control prioritized data collection during the critical moments, with hopes that the solar batteries might regain functionality with a change in the sun's angle. Kuninaka suggested that a potential misalignment might be the cause of the issue.
Prime Minister Fumio Kishida celebrated the successful landing but acknowledged the need for a "detailed analysis" of the solar cells. NASA Chief Bill Nelson extended congratulations to Japan, emphasizing the value of collaboration in space exploration.
Despite the solar panel setback, JAXA remains optimistic about SLIM's mission. The spacecraft aimed for a crater where the Moon's mantle is believed to be exposed. Two detached probes—one with a transmitter and another equipped with a mini-rover capable of beaming images—were part of the mission's objectives.
Harvard-Smithsonian Center for Astrophysics astronomer Jonathan McDowell deemed the mission a "big success," despite the solar panel glitch. Speculating on potential causes, McDowell mentioned loose wires, incorrect connections, or an upside-down lander obstructing sunlight.
As the global interest in lunar exploration resurfaces, with efforts from Russia, China, South Korea, and the United Arab Emirates, setbacks and challenges are inevitable. The recent achievements and hurdles underscore the complexities of venturing beyond Earth's atmosphere, emphasizing the collaborative and exploratory spirit that defines humanity's pursuit of the cosmos.
