An ISS orbit correction maneuver, previously scheduled for February 1, was performed today, using the engines of #ProgressMS20. After it, the average altitude of the station's orbit increased by 2.4 kilometers and amounted to 417.8 km above the Earth’s surface.

Когда не знаешь, что ответить, лучшая стратегия - это забанить. Именно так считает Дмитрий.

T-15 min: #ProtonM is ready to launch the Elektro-L №4 satellite from Pad 81 on Baikonur. Here is the live coverage: https://www.youtube.com/watch?v=dwPkVEgw6RY

Soyuz 2.1a with #ProgressMS22 cargo ship has been rolled out this morning and is now vertical on Pad 31 on Baikonur. The launch is scheduled for February 9, at 06:15 UTC.

As expected, the Council of Chief Designers recommended to extend the life of the Russian segment of the ISS until 2028. The next stage is the Scientific and Technical Council of Roscosmos, after which the proposal must be approved by the government. https://t.me/roscosmos_gk/8332

In 30 minutes, #ProgressMS20 will be undocked from the ISS. Here’s the live coverage: https://www.youtube.com/live/h9OiV7Fej3s

#SoyuzMS23 is being fueled on Baikonur. After that, it will be brought to the assembly and test building for pre-launch tests. The launch is scheduled for February 20, it will fly in an automatic mode to become the rescue ship for the crew of the damaged Soyuz MS-22.

Soyuz 2.1a with #ProgressMS22 cargo ship is ready for launch on Pad 31 of Baikonur cosmodrome. The launch is scheduled for 06:15 UTC. Here is the technical coverage (without speakers): https://www.youtube.com/live/B1l8Z17gwKk

#ProgressMS22 will fly to the ISS by the classic 2-days rendezvous profile. On February 11, at 08:47 UTC it will dock to the Zvezda docking port, which has been left two days ago by Progress MS-20. If the docking is successful, Progress MS-21, another Russian cargo ship currently docked to the ISS, will undock from the Poisk module to clear the room for the automatic docking of Soyuz MS-23. This is why the successful launch and docking of #ProgressMS22 is so important: if something goes not by the plan, the whole “space Tetris” will be at risk.

#SoyuzMS23 has been assembled with the interstage of the third stage of Soyuz rocket. It will fly in an autonomous mode, so Roscosmos will use the opportunity do deliver so additional cargo with it. There will be 429 kg of equipment and experiments.

You won’t believe me, but according to Vladimir Degtyar, the general director of Makeyev Rocket Design Bureau, the company will begin research on the creation of SSTO launch vehicle #Corona this year. The development of Corona began in 1992, but in 2012 was stopped due to the lack of funding. In 2016, they planned to resume it, but the work was stopped again. I don’t know what they hope for nowadays. I’m also not sure how far they've come in 10 years of development, but now they're planning to do engineering research that isn't even a design project. According to Degtyar, the #Corona will have an extremely low cost of putting the payload into orbit, due to the reusability of about 100 times. The launch mass will be 302-315 tons, height - 42.15 m, length - 38.07 m. Payload to LEO from Vostochny cosmodrome) 5.5 tons. The picture above is from the presentation from 2016 (I haven’t found good copies of the new one). The numbers are a little bit different, but the design should be similar.

Aaaaand... the second round! Rumors say, a leak appeared in the #ProgressMS21 which should be deorbited on February 18. The situation, according to the former head of Roscosmos PR service Dmitry Strugovets, is quite similar to the accident with Soyuz MS-22.
