EDB Fakel’s thrusters continue their successful operation aboard spacecraft.

Spektr-RG has completed its transit to the vicinity of the second Lagrange point (L2).

On October 21, 2019, the specialists of Lavochkin Research and Production Association (a member of Roscosmos State Corporation) carried out a transit correction of Spektr-RG to its nominal trajectory. It means that the spacecraft has completed its transit phase to the vicinity of libration point L2 in the Sun-Earth system. After completion of pre-adjustments for the telescopes ART-XC (Space Research Institute of the Russian Academy of Sciences, Russia), eROSITA (MPE, Germany) aboard the spacecraft the observatory will proceed to the primary scientific mission, which is to develop an overall sky map both in soft (0.3-8 keV) and hard (4-20 keV) X-ray spectra with an unprecedented sensitivity.

In the course of its 100-day flight Spektr-RG did 2 corrections which ensured that the spacecraft reach the orbital position in the vicinity of the second Lagrange point (L2) in the Sun-Earth system.

Spacecraft Spektr-RG was launched on July 13, 2019, from the Baikonur cosmodrome. This spacecraft was developed within the framework of the Federal Space Program of Russia by order of the Russian Academy of Sciences with German participation. The observatory is equipped with two unique X-ray reflecting telescopes: ART-XC (Space Research Institute of the Russian Academy of Sciences, Russia) and eROSITA (MPE, Germany) that operate on the principle of grazing incidence X-ray optics. The telescopes are installed on the space platform Navigator (NPO Lavochkin, Russia) adapted to the mission.

The Principal investigator of the mission is academician Rashid A. Syunyaev; the head research for the telescope ART-XC (Russia) is doctor of physical and mathematical sciences Mikhail Pavlinskiy; the head of research for the telescope eROSITA (Germany) is doctor Peter Predel.

It is expected that in the course of the sky survey Spektr-RG will discover about million accreting super-massive black holes, 100 000 galactic clusters, hundreds of thousands of stars with active coronas and accreting white dwarfs, tens of thousands of star-forming galaxies and many other objects. These data are extremely important for understanding the distribution of matter in the Universe, the role of the dark energy in its development and the origination and growth of super-massive black holes.

EDB Fakel has been producing propulsions for different purpose spacecraft for 40 years and we are proud that our products operate reliably and accomplish the mission goals.
