The probe of NASA has photographed an asteroid to Benn


The OSIRIS-REx spacecraft bears payload from five scientific devices which it will use for studying of an asteroid. Further the probe has to sit down on Benn and take soil samples. The OSIRIS-REx spaceship has photographed an asteroid to Benn from distance about 330 km. The picture has been made on October 29, its processing has taken four days. In a minute while OSIRIS-REx took the picture, to Benn has turned on 1,2 °, Gizmodo writes. "The spacecraft moved when made these photos the PolyCam camera, and to Benn has turned by 1,2 degrees within nearly one minute which has passed between the first and last pictures. The team used a superpermission algorithm to unite eight images", - have emphasized in NASA. The OSIRIS-REx spacecraft bears payload from five scientific devices which it will use for studying of an asteroid. Further the probe has to sit down on Benn and take soil samples. Return to the earth of the device is planned for 2023. In addition to a main objective of a mission for return of a unique sample from an asteroid, OSIRIS-REx will also study a surface and structure of an asteroid, measures influence of sunlight on his orbit. "In December, 2018 we will begin to receive images with MapCam, one more of mission cameras, by means of color filters. It will allow us to create color cards and to study geographical distribution of various materials on Benn, including the silicates changed by presence of liquid water", - Javier Licandro, the researcher from from Instituto de Astrofísica de Canarias which was engaged in processing of this image has told. To Benn treats carbon asteroids of a spectral class B. It is supposed that similar asteroids could be suppliers of complex organic compounds and waters to young Earth. Orbits of Earth and to Benn are crossed, scientists estimate probability of collision with him at one to 4 thousand. We will remind, earlier in NASA have reported that the large asteroid of SP1 approaches Earth. By the sizes it is possible to compare him to clock tower Big Ben in London.
