Are we about to find out the moon’s origin? Japan’s space agency says it may now have clues

An unmanned lunar spacecraft has captured and transmitted information analyzing 10 lunar rocks, a greater-than-expected achievement that might assist present clues concerning the origin of the moon, a Japan space company official stated Wednesday.

For 4 days, the Sensible Lander for Investigating Moon, or SLIM—which landed on the moon final month—has used its multi-band spectral digital camera to review rock composition, and labored on inspecting lunar rocks, stated Japan Aerospace Exploration Company mission supervisor Shinichiro Sakai.

The lunar mission is Japan’s first. The spacecraft made a historic precision landing on Jan. 20, although it landed the unsuitable means up, with its solar panels initially unable to see the sun and was turned off after a short communication with Earth. However on the eighth day, it began working, permitting it to efficiently reestablish communication with the command middle at JAXA on Earth.

A black-and-white photograph transmitted quickly after SLIM was reactivated confirmed the bumpy lunar floor, together with six rocks. The craft ultimately obtained information from 10 rocks altogether, all of which have been given the names of canine breeds, corresponding to “Akitainu,” “Beagle” and “Shibainu.”

“We hope that the rock evaluation will lead us to the origin of the moon,” Sakai stated. By evaluating the mineral compositions of moon rocks and people of Earth, they might discover out if the rocks have widespread components, he stated. In keeping with the “giant-impact” speculation, the moon is believed to have shaped because of the Earth colliding with one other planet, and a smaller mass spinning off of them.

The JAXA staff anticipated SLIM to review and analyze just one rock, so having information on 10 rocks was a trigger for celebration, propelling the staff to pursue finding out the moon’s origins.

SLIM is presently “hibernating” in one other lunar evening that may final until late February. It stays unknown if the probe and its spectroscope will survive the extreme chilly evening temperatures and have the ability to “get up” as soon as daylight returns.

The spacecraft had landed about 55 meters (60 yards) away from its goal, close to the Shioli crater, a area coated in volcanic rocks. It is probably the most exact touchdown in comparison with earlier moon missions that usually aimed for flat areas at the least 10 kilometers (6 miles) vast.

If the lander had not encountered a last-minute failure in one of many two major engines that induced a harder-than-planned touchdown, SLIM’s landing was estimated to be inside meters of the goal, JAXA stated.

SLIM carried two autonomous probes which have been launched simply earlier than landing, recording the touchdown, environment and different lunar information. The 2 small probes had accomplished their mission of recording SLIM’s preliminary work and have since stopped working.

The touchdown made Japan the world’s fifth nation to achieve the moon, after the US, the Soviet Union, China and India.
