Mikhail Pavlinsky ART-XC X-Ray telescope and Integral observatory look at Swift J1727.8-1613 X-Ray nova – the brightest object in the summer X-ray sky of 2023.

Presentation was held on August 30, 2023. The Earth&Universe popular scientific journal is published by Nauka Publishing House and the Presidium of the Russian Academy of Sciences. Academician Lev M. Zelenyi, the Academic Advisor of IKI, has been acting as its editor-in-chief since 2018.

Science and Technology Decade Website (within the Science and Universities national project) now gives an opportunity to browse the list of scientific educational programs in Russian educational insitutes.

Using SRG/eROSITA X-ray data, researchers studied the properties of hot gas in galaxy clusters at large distances from their centers. The results of the study are published in MNRAS and are available on arXiv.org.

В соответствии с программой полета автоматической станции «Луна-25», 19 августа была предусмотрена выдача импульса для формирования ее предпосадочной эллиптической орбиты. Около 14:57 по московскому времени связь с автоматической станцией прервалась. Реализованные 19 и 20 августа мероприятия по поиску «Луны-25» и вхождению с ней в связь результатов не дали. По результатам предварительного анализа, в связи с отклонением фактических параметров импульса от расчетных, автоматическая станция перешла на нерасчетную орбиту и прекратила свое существование в результате столкновения с поверхностью Луны. Вопросами выяснения причин потери «Луны-25» займется специально формируемая межведомственная комиссия.

Luna-25 mission, built at Lavochkin Association (part of Roscosmos State Space Corporation), continues its flight along the circular orbit around the Moon. Its scientific instruments were switched on several times in the flight and sent back first data.

Astrophysicists from IKI and Ioffe Institute of the Russian Academy of Sciences studied compact star cluster Westerlund 2. The paper with the results of the study is accepted for publication in MNRAS and is available on arXiv.org.

Luna-25 mission, currently in a circular orbit around the Moon, sent back first images of the far side of the Moon made by STS-L TV-cameras.

Today Luna-25 station, built at Lavochkin Association (part of State Space Corporation Roscosmos), entered the circular polar orbit around the Moon and became its artificial satellite.

The IKI RAS has completed an express analysis of telemetry and measurement data of scientific instruments on board the Luna-25 automatic station, performed on August 13, 2023 in two sessions of the first activations at a distance of about 310 thousand km from the Earth. All instruments showed full operability and readiness for lunar exploration. Their analog and digital components and blocks worked perfectly.
