Japan's spacecraft touches a distant asteroid on Thursday, before shooting a bullet into the space rock to hold a few scams that will eventually be returned to Earth.

After launching in 2014 by the Japan Aerospace Agency (JAXA), Hayabusa 2 bell reached Ryugu asteroid in June 2018, after a 2 billion mile trip. In the months since then, the refrigerator craft drops a pair of small rovers on the rock space and has interfered closer to its face. If everything goes back the plan, he will fire his lovers and settle on the asteroid on Thursday for about 6 p.m. EST (about 8 a.m. local time in Japan on February 22).

Originally, the landing was planned for last October, but JAXA suspended after the instruments on board the nets found that the surface of the asteroid is not covered with a dusty soil (regolith) but it is spread with rocks – some scientists had not predicted.

"The expected topography of a fine powder regolith on the surface of Ryugu was not found," said members of the Hayabusa 2 team in February 14 on the JAXA website. "It took time to investigate the safety of the spacecraft during TD," he said, using an abbreviation for "touchdown."

If Hayabusa 2 succeeds successfully, the next challenge will be the bullet fire and then use a container to collect samples of the material raised from the surface by the effect.

The JAXA processed the Earth process, placing a bullet to a gravel carried out within a chamber designed to denote space vacuum. Researchers decided that the resulting rocky debris would be small enough to collect and be brought back to the Earth to analyze. But this will take a little while: samples have not been arranged to arrive here until the end of 2020.
