On Sunday, September 27, ISS-64 mission crews both prime and back-up left for Baikonur from Chkalovsky airfield located in Moscow region by two different planes. In several hours the planes successfully landed at Krainy airfield.

Soyuz MS-17 prime and back-up crews successfully passed exams in GCTC, - press-office representative reported. “Both prime comprising Roscosmos cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov and NASA astronaut Kathleen Rubins and back-up crew including Roscosmos cosmonauts Oleg Bovitsky and Pyotr Dubrov and NASA astronaut Mark Vande Hai successfully passed two-weeks long examination session getting an “excellent” mark”, - the source stated.

On Thursday, September 10, 2020, specialists of the Roscosmos State Corporation accomplished ISS orbit adjustment maneuver with the help of Progress MS-14 cargo vehicle.

An air leak has occurred on the ISS. The entire crew took refuge in the Russian segment of the station. The entire crew of the International Space Station (ISS) will spend the next three days in the Russian Zvezda module. The devices recorded an air leak at the station.

The Crew Dragon spacecraft splashed down in the Atlantic Ocean off the coast of Florida, completing the first manned flight to the International Space Station. It touched the water at the estimated 21:48 Moscow time.

The crew of the 64th long-term expedition to the International Space Station will undergo joint training at the Cosmonaut Training Center in preparation for the flight, which is scheduled to begin in October this year. The ISS-64 crew includes Roscosmos cosmonauts Sergei Ryzhikov, Sergei Kud-Sverchkov and NASA astronaut Kathleen Rubins. The backup crew includes Roscosmos cosmonauts Oleg Novitsky and Pyotr Dubrov, NASA astronaut Mark Vande Hai.

45 years ago, on July 15, 1975, the first joint space flight of representatives of different countries started in the history of mankind. The start of the Soyuz Apollon pilot project was laid on October 26-27, 1970. At this time, Moscow hosted the first meeting of Soviet and American experts on the compatibility of the means of approaching and docking of manned spacecraft.

SpaceX Crew Dragon manned mission launch from Cape Canaveral initially planned for May 27 was shifted due to the low cloud ceiling. New attempt is to be made on May 30.

At the NPO "Energomash" (part of Roscosmos State Corporation) on December 6, 2019 representatives of the American company "Orbital Sciences Corporation" signed the documents for the next batch of four engines RD-181.

Petr Levochkin, chief designer of NPO "Energomash, designer and manufacturer of the famous "RD-180" family of engines, commented on the PR statement of Elon Musk about the “superiority” of "Raptor" engine, created by SpaceX: “The SpaceX company creates the "Raptor" engine on oxygen and methane components or, as is customary in the Russian classification, the gas-gas scheme. In such schemes, such a pressure level in the combustion chamber is not something extraordinary - in our designs for these schemes we lay down the pressure level in the chamber over 300 atmospheres. However, Mr. Musk, not being a technical specialist, does not take into account that the "RD-180" engine for the Atlas launch vehicle uses a completely different fuel circuit - “oxygen-kerosene”, and these are another parameters of the engine operation. It is like comparing a diesel and a gasoline internal combustion engine. Despite the fact, that our companies are competitors, we as engineers welcome the first successes of colleagues from SpaceX in the field of rocket engine building. Indeed, during the development of the Raptor engine, American engineers reached a record pressure level in the chamber. This indicates a fairly high level of development and production processes at SpaceX. ”
