Japan Successfully Launches Lunar Mission 'Moon Sniper' with H-2A Rocket
In a historic leap towards lunar exploration, Japan has made a remarkable stride by launching its lunar spacecraft, 'Moon Sniper,' using its indigenous rocket, the 'H-2A,' on September 7, 2023. This monumental achievement puts Japan on the cusp of becoming the fifth country globally to set foot on the Moon, with the planned lunar landing slated for February of the following year.

A Giant Leap for Japan
The Japan Aerospace Exploration Agency (JAXA) spearheaded this ambitious lunar mission. The liftoff from the Tanegashima Space Center in southern Japan unfolded as planned, with the H-2A rocket successfully deploying the Smart Lander for Investigation Moon (SLIM). This mission, valued at $100 million, aims to accomplish a lunar landing by February 2024, potentially making SLIM the smallest and lightest spacecraft to ever touch down on the Moon's surface.
Mitsubishi Heavy Industries and the 47th H-IIA Rocket
The H-2A rocket, a marvel of engineering, is the brainchild of Mitsubishi Heavy Industries and marks the 47th H-IIA rocket launched by Japan since 2001. This impressive track record has brought Japan's rocket launch success rate close to a remarkable 98%. The H-2A rocket's reliability has played a pivotal role in facilitating Japan's lunar exploration endeavors.
XRISM Mission: A Joint Venture
While 'Moon Sniper' is undoubtedly the highlight of this mission, it's not the only feat Japan has accomplished. The H-2A rocket also carried the X-ray Imaging and Spectroscopy Mission (XRISM) satellite into space. XRISM is a collaborative effort involving JAXA, NASA, and the European Space Agency.
This satellite is set to make high-resolution X-ray spectroscopic observations of hot gas plasma winds coursing through galaxies. Its scientific studies will focus on unraveling the mysteries of the mass-energy flux, structure, and evolution of celestial bodies. Furthermore, XRISM will unveil the chemical elements that constitute our universe, shedding light on the aftermath of the Big Bang, during which only the four lightest elements - hydrogen, helium, lithium, and beryllium - were formed.
Lunar Mission Challenges and Triumphs
Japan's journey to the Moon has been marked by both challenges and triumphs. In the previous year, Japan faced two failed attempts at lunar landings. JAXA lost contact with the Omotenashi lander, and a subsequent landing attempt in November ended in failure. The Hakuto-R Mission 1 lander, built by the Japanese startup iSpace, tragically crashed while trying to make a lunar landing in April.
However, the successful launch of 'Moon Sniper' signifies a turning point. It marks the world's third lunar mission in the past two months, following Russia's Luna-25 mission failure and India's triumphant Chandrayaan-3 mission. Building on this success, the Indian Space Research Organisation (ISRO) and JAXA have joined forces for the Moon's Polar Exploration Mission (LUPEX) as part of the upcoming Chandrayaan-4 mission. ISRO will craft the lander for the mission, while JAXA will supply its H3 rocket. LUPEX will concentrate its efforts on exploring the Moon's south pole.
The Genesis of JAXA
The Japan Aerospace Exploration Agency (JAXA) was officially established in October 2003. Headquartered in Chofu, Tokyo, Japan, JAXA has been at the forefront of space exploration and innovation. Its contributions to lunar exploration are a testament to Japan's commitment to pushing the boundaries of space exploration and expanding our understanding of the cosmos.
