Jakarta – The Japanese spacecraft Hayabusa2 is preparing to blow up the asteroid Ryugu. This is a continuation of the Hayabusa2 mission developed by the Japanese space agency (JAXA) to examine the origin of life on Earth.

Ryugu is part of a primitive rock called the C-type asteroid. It is believed that this asteroid contains organic material and water 4.6 billion years ago, or at the time of the formation of the solar system.

To blow up Ryugu, Hayabusa2 was equipped with a small pendulum & # 39; (SCI) that is like a bomb, also known as explosive. This device is a cone-shaped container containing plastic explosives and the bottom covers 2 kg in weight.

This morning in Japan, Hayabusa2 approached the surface of Ryugu with a distance of about 500 meters, after which the SCI device will be launched toward the surface of the asteroid. After that, Hayabusa2 will leave the area around the Ryugu to avoid splinters of explosions or collisions with Ryugu.

Before leaving Ryugu, Hayabusa2 would leave a small camera called DCAM3. This camera will monitor the explosion created by SCI at a distance of about 1 km and send the image to Hayabusa2.

The SCI is scheduled to explode automatically after 40 minutes and will create an artificial crater on the Ryugu surface. This crater will have a diameter of 10 meters if the surface is sandy, but if the surface is rocky, the diameter is only about 3 meters.

"We expect the accuracy of impact (SCI) around a radius of 200 meters to be very large … we expect to have a hole somewhere in the very large area," said Yuichi Tsuda, Hayabusa's project manager2, quoted by BBC on Friday. 5/4/2019).

After that, Hayabusa2 will take about two weeks to return to Ryugu and find the artificial crater. Then Hayabusa2 will begin to observe the material that is spit out & # 39; by the explosion.

Hayabusa2 is expected to return to Earth in 2020, bringing the material he received from Ryugu. This project itself has been started since 2014.
