"Hayabusa-2" probe can not reset the marker on the crater of the asteroid Ryugu

The spacecraft Haiabusa-2, currently located near the Rigu asteroid, faces a problem in preparing for the second soil collection operation. At the beginning of April 2019 he carried out a successful bombing and created a large crater on the surface of the site. From May 14th to May 16, he had to reset the target marker over the trench area to keep the camera in place, but failed.

Initially, everything was on its way – the probe began to approach the surface of the asteroid. It was expected that the marker would drop from a height of 10 meters from the surface of the asteroid, but when the station was at a distance of 50 meters, the drop was suddenly stopped in automatic mode. Subsequently, the station begins to return to its previous 20-kilometer orbit and the marker remains with it.

The cause of the failure is still unknown, but researchers are carefully studying telemetry data. There are several assumptions about the cause of the failure: first, due to the low reflection capability of the asteroid, the station's lord may lose control of the distance to the site. Secondly, the object is gradually warmed by the sun and the appliance may fail due to temperature rise.

Anyway, just because of the temperature rise, Hiabausa-2 will not be able to stay close to the asteroid very soon. Generally, the device has only a month and a half to collect the soil – otherwise scientists will have to settle for the samples collected during the first attempt. Recall that they intend to find rock samples that have not been subjected to any impact since the formation of the Solar System.
