The Japanese probe actually created a crater – Space – Science and Technology on the asteroid

The Japanese spacecraft Hajabusa 2 successfully created an artificial sampling crater on the asteroid Ryuga in April to be analyzed on Earth.

Japan's Space Agency JAXA released on Thursday, April 25th
Twitter image that confirmed the creation of a crater after hitting the projectile.
Probe may take samples from the crater in May, which they will later transport
on the ground.

Hajabusa 2 descended on Thursday at the end of a three-day operation
about 1.6 kilometers above the surface where the projectile impact site
she photographed.

Then the apparatus came back to the parking position, which is
20 kilometers above the surface of Ryuga.

Scientists have not yet known the shape of the spot on April 5th
fired a two-kilogram copper projectile. The object then probe by
Reuters sent out when it was about 500 meters above the surface
asteroids. According to available information, the device exploded 40 minutes after

JAXA announced that the probe had also released its probe shortly after the projectile was fired
microstelite with a camera that was supposed to capture the whole event. shortly after
surface bombardment thanks to photography so experts knew that
the projectile hit the surface and that part of the surface was ejected into the impact
surroundings, but they did not have a detailed photo.

According to the European Space Agency (ESA), it should have a crater
width about two meters.

The probe will return to the crater in the coming weeks to get out of it
took the dust. Hajabusa 2 tried to get samples at the end of February
from the Ryuga surface using a collecting nozzle. The apparatus was close at that time
to a pre-selected platform of six meters and a nozzle for a moment
has reached surface contact.

Whether the sample has actually been removed will only be clear after returning to
Earth. There is no device in the probe that would have the presence of material
confirmed in the storage case. JAXA after the video evaluation stated that
the amount of particles released during asteroid surgery increases
probability of successful collection.

The Earth should return to Earth with potentially collected material
in 2020. Hajabusa 2 arrived at the asteroid for three and a half years last year
in June. The MINERVA-II 1 container with a pair of robots has already been transported to the surface
called Rover-1A and Rover-1B, which send data and photos to Earth, and
also the German MASCOT landing module. Carries MINERVA-II 2 Container
in which is the Rover-2 robot, the surface landing is scheduled for July.
