The secret of the solar system in 0.1 grams … Collection of “Hayabusa 2” capsules


◀ Anchor

Here is the news from space.

Dirt from asteroids far away in the universe has come to Earth.

It was picked up and sent by a Japanese space probe.

It flew at a great distance over 13,000 times the distance between the Earth and the Moon.

Expectations are growing that this soil could unlock the secrets of the creation of the Earth and the solar system.

Correspondent Ko Hyun-seung reports from Tokyo.

At 2:30 a.m., a mass of light appeared in the astonished night sky with a long tail hanging like a comet.

A 40-cm-diameter capsule detached from the Japanese asteroid probe Hayabusa2 entered the atmosphere at a speed of 12 kilometers per second and fell into the desert of South Australia.

Applause and cheers erupted from the control center near Tokyo, where I watched as I held my breath.


[츠다 유이치/일본우주항공기구 팀장]“The radio wave is cut off, it means landing. “It was a wonderful surge of atmosphere.”

The research team was able to recover the capsules by monitoring the signal and began analyzing the gas contained in the capsules before being transported to Japan.

Launched in December 2014, Hayabusa 2 arrived in the air over the asteroid Ryugu, 340 million kilometers from Earth in three and a half years.

The metal bullets were then fired at the asteroid’s surface to create a pool about 10 meters in diameter, then landed on the asteroid and took a sample of the soil beneath the surface.

Shortly afterwards, Hayabusa 2 headed home and after about a year, reached 220,000 kilometers above the Earth and sent a capsule with the Earth sample.

The sample collected from Hayabusa2 is about 0.1 grams.

At the academy, this means that Hayabusa 1 brought land to the surface of the asteroids in 2010, and this time, it was the first time to provide soil below the surface.

Surface soil can be deteriorated by meteorite impact and radiation, the so-called “Spatial atmospheric effect”, but the soil beneath the surface is likely to remain the same when the solar system was born 4.6 billion years ago.

[야마카와 히로시/JAXA 이사장]“We look forward to achieving results that are approaching the process of creating the solar system and the origin of the water that is transmitted to Earth.”

The Japan Aerospace Administration plans to share half of the samples with foreign research institutes such as the US Aeronautics and Space Administration and to reserve some for future research.

Hayabusa 2 completed its first mission after sailing 5.2 billion kilometers in 6 years and plans to fly 10 billion kilometers for another 11 years to try to land on another asteroid.
