    Japanese Space Agency Attempts Historic Robotic Moon Landing

    Less than 24 hours after a U.S. moon lander met its demise upon reentering Earth’s atmosphere, the Japanese space agency embarked on its first-ever attempt at a robotic moon landing. The Japan Aerospace Exploration Agency (JAXA) launched the Smart Lander for Investigating Moon (SLIM) spacecraft from the Tanegashima Space Center back in September. Today, the spacecraft initiated its final descent, and while telemetry indicated a successful landing, confirmation of its survivability is yet to be determined.

    The SLIM spacecraft, weighing 1,600 pounds, entered an elliptical orbit around the moon’s poles on Christmas Day and transitioned to a circular orbit at an altitude of 373 miles earlier this month. The mission’s objective was to study the moon’s surface in unprecedented detail, gathering vital information about its geological features and composition.

    As the spacecraft began its final descent, onboard telemetry data showed that SLIM was closely following its pre-planned trajectory. The vehicle paused multiple times to capture photographs of the lunar surface and compared them to onboard maps for precise navigation. The descent appeared to be smooth, with SLIM expertly flipping from a horizontal-to-vertical orientation as it gradually approached the surface.

    In a unique two-step procedure, the spacecraft was designed to release two micro rovers just before touchdown. With the intention of landing on a slope, SLIM’s rear legs were meant to make initial contact with the surface, followed by a slight forward tilt to bring down its front legs. At 10:20 a.m. EST, telemetry indicated a successful landing. However, there was no immediate communication from the spacecraft to confirm its condition.

    While JAXA is still assessing the situation, early signs are promising as the NASA Deep Space Network, responsible for communicating with spacecraft throughout the solar system, continued to receive telemetry from either SLIM or one of the micro rovers after landing.

    This landmark mission attempts to add Japan to the list of nations that have successfully landed on the moon, joining the United States, Russia, China, and India. Private ventures, too, have sought lunar landings, though none have achieved their goals thus far. Regardless of the final outcome, the Japanese space agency’s historic endeavor serves as a testament to humanity’s ongoing exploration and curiosity about the moon and beyond.
