The Hubble telescope went into safe mode due to a malfunction in the orientation system

The Hubble Space Telescope on October 7 was transferred to safe mode for an indefinite period due to the failure of the gyroscope in the orientation system. About this in her twitter reported  Rachel Oosten, deputy head of the mission at the Space Telescope Science Institute in Baltimore.

The last replacement of all gyros on board the telescope was carried out by astronauts in 2009, during the last maintenance operation . To maintain its full working capacity, Hubble needs to have at least three of the six gyroscopeworkers , which provide guidance to the telescope in three axes. Previously, there were problems with one of the gyros, which was subsequently disabled. Now the engineers will try to turn it on, but if this fails, the telescope will go into operation using one gyroscope (the second will be used as a backup). He will still be able to carry out his scientific program, although not all parts of the sky will be available for observation.

The Hubble Space Telescope is one of the most well-known and effective orbital observatories operating today. It was launched into space in April 1990 and for more than two decades of working in near-earth orbit, it has accumulated and transmitted to Earth a huge amount of scientific data in various fields of astrophysics and cosmology, the total amount of which is in the tens of terabytes. In particular, the observations made by the telescope played a key role in the discovery of the accelerated expansion of the Universe; you can read about this in our material “Worked at 5 in the square” .

Earlier we talked about how the Hubble telescope helped to study the structure of the residual disk in a distant star, found a  close analogue of ancient massive galaxies, and saw  the furthest star.
