Japan will blow a crater into an asteroid for science – BGR



The Japanese spacecraft Hayabusa2 does some big things during the asteroid known as Ryugu. JAXA, the space program of Japan, arrived in space rock last year and, after much planning, shot a shell at its surface late last month to collect some samples of its surface. Now, JAXA plans even more daring maneuvers

Getting samples from the surface of Ryugu is great, but JAXA also wants to bring some of the material from the asteroid itself. Hayabusa2 is not equipped with a drilling or digging tool to drill the surface of the asteroid, but it has brought some explosives.

In order to obtain groundwater, the probe will release what is called a hand-blow in the sky over Ryugu. The impactor consists of a larger copper projectile and a bursting charge. It's a little like a one-shot cannon, and once it's released and Hayabusa2 moves to a safe distance, he will shoot on the surface of the asteroid and produce a large crater.

The crater, which according to JAXA will be about one meter deep and up to 1

0 meters in diameter, will be the place where Hayabusa2 extracts its underground sample if everything goes well. At this point, the safety of the spacecraft is a top priority for JAXA, and although researchers would like to take a sample of the asteroid, the green light for touch and sampling will depend on whether they are a safe place for

The release of the impactor is currently scheduled for April 5, but it will take at least two weeks before the dust and debris are cleared and JAXA can see the hole well
