Spektr-RG is a German-Russian high-energy astrophysics space observatory which was launched on 13 July 2019. It follows on from the Spektr-R satellite telescope launched in 2011. The primary instrument of the mission is eROSITA, built by the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany. It is designed to conduct a seven-year X-ray survey, the first in the medium X-ray band less than 10 keV energies, and the first to map an estimated 100,000 galaxy clusters. This survey may detect new clusters of galaxies and active galactic nuclei. The second instrument, ART-XC, is a Russian high-energy X-ray telescope capable of detecting supermassive black holes.

Blastoff! Russia Launches New X-Ray Observatory
A Russian Proton-M rocket launched the Spektr-RG X-ray space observatory for Roscosmos and the German Aerospace Center from Baikonur Cosmodrome, Kazakhstan on July 13, 2019. -- Full Story: https://www.space.com/russia-launches-x-ray-space-observatory-spektr-rg.html
Запуск астрофизической обсерватории Спектр-РГ
Пуск ракеты-носителя «Протон-М» с разгонным блоком «ДМ-03» и новой орбитальной обсерваторией «Спектр-РГ» запланирован 13 июля в 15:31 мск. Главная ее миссия — исследование Вселенной в рентгеновском диапазоне электромагнитного излучения, создание «карты» видимой Вселенной, на которой будут отмечены все достаточно крупные скопления галактик.
The eROSITA X-ray telescope - On the hunt for Dark Energy
Very little is known about the Universe. The ingredients that make up four percent of its energy density – ‘normal’ material such as protons and neutrons – is only a very small part of the ‘Universe recipe’. What the other 96 percent is composed of remains a mystery. Today it is believed that 26 percent is Dark Matter. However, the largest share, estimated at 70 percent, is comprised of Dark Energy. To track this down, scientists must observe something unimaginably large and extremely hot. Galaxy clusters are composed of up to several thousand galaxies that move at different velocities within a common gravitational field. Inside, these strange structures are permeated by a thin, extremely hot gas that can be observed through its X-ray emissions. This is where eROSITA’s X-ray ‘eyes’ come into play. They allow to observe galaxy clusters and see how they move in the Universe, and above all, how fast they are travelling. We hope that this motion will tell us more about Dark Energy.

e-ROSITA: Tearing the skies apart.
In this video I talk about the upcoming e-ROSITA mission on board of Spekr-RG due to launch Friday 21st June 2019. How X-ray detectors work, what they are good for looking at and how this mission will tear the skies apart.

eROSITA for eRRbody: How an X-Ray map of the sky will help us understand dark matter
I'm so excited to join the eROSITA team! Here's why.
eROSITA is an X-ray survey of the entire sky launching on June 21, 2019. Over the next two years, it will produce the highest-resolution, faintest all-sky X-ray maps, revealing over 7,000,000 supermassive black holes and 100,000 galaxy clusters. Each of these high-energy sources can be used to probe the nature of dark matter and dark energy. In this video, I explain how we cosmologists use galaxy clusters.
