Roscosmos conducted a test fire of the first stage of the Soyuz-5 rocket.

Roscosmos reports successful first stage fire tests missiles Soyuz-5. The tests took place at the Scientific Test Center of the Rocket and Space Industry and are the final stage of ground development. During the tests, the RD-171MV oxygen-kerosene engine, with a thrust of 800 tons, fired for 160 seconds. Notably, the RD-171MV rocket engine uses environmentally friendly propellants—kerosene and liquid oxygen. The tested first stage of the Soyuz-5 rocket will form the basis for a future super-heavy rocket.

The Roscosmos press service notes that these tests pave the way for the launch of Soyuz-5 from the Baikonur Cosmodrome later this year. The tests were conducted as planned, verifying the interaction of all onboard and control systems.

Roscosmos is also preparing the Soyuz MS-28 manned spacecraft for launch. This November, it will deliver the crew of the 74th long-duration expedition to the International Space Station. The spacecraft has already undergone tests in the anechoic chamber at the Baikonur Cosmodrome. The spacecraft's onboard radio systems have been tested, as well as the Kurs-NA equipment, which will be responsible for the rendezvous and docking of Soyuz MS-28 with the ISS.

NASA astronaut Christopher Williams will be the "third" member of Expedition 74. He has no spaceflight experience, but he definitely drinks Russian vodka.

[tralflot1832]

And he knows all the "Russian" jokes before launch and the song "They don't take people like that into cosmonauts."

[Gorynych1]

Good afternoon, Andrey. What are they taking him for? Experiments? Belka and Strelka were much smarter. Where's the intelligence on his face?

[tralflot1832]

Gorinych 1. Christopher's main specialty is a doctor. So, for experiments.

[Gorynych1]

How I felt. you must be such a cheerful monkey

[Alex_12]

No, they'll ask why you need so much alcohol. He'll say, "Well, I'm a doctor."

Flight engineer. Standard position. Sergei Mikayev, who's flying with him, is also a flight engineer, and this is his first flight as well. The commander is Sergei Kud-Sverchkov, his second flight.

And I understand that your comment is meant as a joke. But Christopher Williams isn't just a doctor, he's an oncologist who has performed radiation therapy on cancer patients. Not only conventional treatments, but also experimental ones, and he also holds a PhD. After all, you shouldn't judge people by their appearance.

[Gorynych1]

A plus from me to you. I didn't mean to offend. Have a nice evening.

[Capt cook]

So, Gorynych, I take it you didn't qualify for these positions? Neither Belka nor Strelka...

[Gorynych1]

Yeah, I'm jealous. Good evening to you. I'll say it again, that was a bad joke. A plus from me.

The promising medium-class launch vehicle Soyuz-5.

In addition to its relatively large dimensions (65 meters in length), the Soyuz-5 will have an impressive payload capacity—a whopping 17 tons. By comparison, the Soyuz-2 and Zenit rockets, which the Soyuz-5 is intended to replace, can lift over 7 tons and 13 tons into orbit, respectively.
Cutting-edge engines will lift this colossus into the sky: the RD-171MV (with record-breaking specific impulse) for the first stage and the RD-0124MS (with world-leading thrust of 800 tons at a weight of 10 tons) for the second. ... The Soyuz-5 will be indispensable when Russia begins assembling the Russian Orbital Station, as it is the one Roscosmos plans to use to deliver the station's base module into Earth orbit. Roscosmos plans to build one rocket per year until flight tests are completed in 2025-2026, and then, if successful, every year.

Work on the Soyuz-5 launch vehicle is nearing completion, according to a report on the Russian government's website on September 6, 2025. Development of the Soyuz-5 medium-class launch vehicle, replacing the Zenit, which was produced in Ukraine, began in 2017. The completion of flight tests of the heavy Angara rocket has finally established the core rocket triad of modern Russia: the light-class Angara-1.2, the medium-class Soyuz-5, and the heavy-class Angara-A5.

It's been coming for a long time now...

MOSCOW, March 8. /TASS/. The flight test program for the advanced Soyuz-5 (Irtysh) launch vehicle includes four launches, the Progress Rocket and Space Center (part of Roscosmos) told TASS on Friday.
...
The first tests are scheduled for 2022, when the rocket will be manufactured and delivered to the Baikonur Cosmodrome. Work on the Soyuz-5 (Irtysh) medium-class launch vehicle is currently proceeding in accordance with the approved technical specifications and the signed contract with the Rocket and Space Corporation Energia, according to the Progress Rocket and Space Center.

Moscow, July 2, 2022, 13:09 PM — Regnum News Agency. The first launch of the new Soyuz-5 launch vehicle will take place in late 2023 or 2024. Roscosmos Director General Dmitry Rogozin announced this in an interview with the Rossiya-24 television channel on July 2.

Roscosmos announced that it will conduct the first test launch of the advanced Soyuz-5 rocket in 2025 from the Baiterek complex at the Baikonur Cosmodrome. This was announced by the head of the state corporation, Dmitry Bakanov.

The first launch of Russia's new Soyuz-5 launch vehicle has been postponed from 2025 to 2026, Interfax reported, citing Ravil Akhmetov, First Deputy Director General and General Designer of the Progress Rocket and Space Center (RSC).

We've been sitting here for a long time... :((

[topol717]

When will they attach the UMPK (Universal Planning Module) to the first stage and return the engines?

[tralflot1832]

You are not aware, they are already working on this. The head of Roscosmos wrote to you personally.

[Magog_]

Could you share a little more information? At least what methods of stage recovery are being considered: aerodynamically, like an airplane; gliding, also like an airplane; and a soft parachute landing; etc.?

[dnestr74]

The comrade is joking, though))))

[Magog_]

Okay, come on, jokers. They've spread some terrible secrets here! I found the relevant articles and read them (just for general information, without any apparent purpose). The project is "in the footsteps of SpaceX," only here they're planning to install aerodynamic control surfaces on the return stage (like the grid on the VB-R77 combat rocket). I haven't seen anything like that with Musk. They want to go straight to the Amur project with engines running on liquid methane (fuel) and oxygen (oxidizer). But no one has allocated any money for Amur yet.

[Alex_12]

And what is the purpose of your interest, citizen? (c)

[BAI]

The tests took place here. All the local Telegram channels have been discussing them since yesterday. I won't say where, though. It's classified, after all.

[Capt cook]

It's good that at least here there is some cooperation.

The Zenit rocket was once touted as a replacement for the Soyuz. That is, they planned to launch cosmonauts into orbit on the same rocket (the Zenit). The Soyuz-5 is a sort of reincarnation of the Zenit rocket, naturally utilizing modern technology. It's just that it's positioned as a pure cargo workhorse, which is a shame.
