The Hayabusa descent module worked in Ryuga almost a year after the end of its service life. Scientists from the mission found out due to the fact that after 10 months the device recorded signals from the module from an area located far from the original landing site.
The Hayabusa-2 probe visited the Itokawa asteroid in 2010 and collected soil samples from a space body. As part of the study of soil from Itokawa, scientists wanted to determine its age – it should be similar to the age of the solar system. It turned out that it amounted to 4.64 billion years, and the diameter of the asteroid exceeded 20 km.
In addition, soil analysis will confirm the theory that many individual meteorites and their progenitors from the asteroid class have an absolutely identical composition.
The Sova landing module reached the surface of the asteroid Ryugu earlier than the main research vehicle. He jumped over the surface of the object, collecting scientific data and using three cameras was engaged in the creation of stereo images of the soil.
The latest data from the “Owl” scientists received on the tenth day of the mission, after which the module stopped communicating. However, in a new data packet sent by Hayabusa-2 to Earth, scientists found evidence that the module survived the mission.
10 months after the “Owl” stopped communicating, “Hayabusa-2” recorded a signal from it, the source of which was far enough from the place where the module was supposed to turn on. This means that for 10 months the module jumped on the surface of Ryugu.
