THE nation aims to become the fifth country to land a spacecraft on the lunar surface with the launch of a low-cost “moon sniper” today that will test precision landing technology designed to further Tokyo’s space goals.
The launch comes weeks after India became the first country to land on the moon’s south pole, sparking an outpouring of national pride and highlighting a new space race that features the private sector.
The Japan Aerospace Exploration Agency (JAXA) mission is scheduled to take off from Tanegashima Space Centre in southern Japan today, according to Mitsubishi Heavy Industries which oversees launches for JAXA and builds the H-IIA rocket (pic) carrying the lander.
The Smart Lander for Investigating Moon (SLIM) craft – dubbed “moon sniper” by JAXA – is set to touch down on the near side of the moon close to Mare Nectaris, a lunar basin that is one of the visible dark spots on the moon.
The mission is meant to demonstrate Japan’s ability to put a lightweight, low-cost craft on the moon within 100m of a designated landing site using an advanced visual navigation system.
The landing is likely to be a “breathless, numbing 20 minutes of terror”, Kenji Kushiki, the sub-project manager of the SLIM mission, said in a blog post on a JAXA website, adding that landing was akin to a “one-shot game that cannot be undone”.
Japan’s efforts to build a homegrown space industry are also on display: The lander was assembled by Mitsubishi Electric, using its landing radars, computers and transponder. Sharp Corp supplied solar cells and Meisei Electric supplied the navigation cameras.
The US$100mil (RM465mil) mission is expected to reach the moon by February after travelling along a looping, fuel-efficient trajectory of Earth to moon orbits.
Delhi last month put its Chandrayaan-3 rover lander down near the moon’s south pole in a US$75mil (RM348mil) mission. That made India the fourth country to land a spacecraft on the moon after the United States, Russia and China.
Two earlier attempts by Japan to land on the moon failed. JAXA lost contact with a lander carried by a Nasa rocket and scrubbed an attempted landing in November.
A lander made by Japanese startup ispace crashed in April as it attempted to descend to the lunar surface. — Reuters
