    Not a fan of fast action. I prefer watching cars rust.

    Now I get it. I do the same with Test match cricket games. 5 days, 8 hours a day.

    Pure bliss.

    Some drama about Nauka. The main propulsion system that is needed to get Nauka to the ISS seems in trouble. The main engine is presently out of order.

    https://twitter.com/RussianSpaceWeb

    Anatoly Zak at RussianSpaceWeb is reporting on twitter.

    Latest info is that they are going to test fire the main engines soon.

    Present status: Don't panic.

    Nauka is to replace the old Pirs module. Pirs was to undock tomorrow. The undocking procedure was stopped for the moment.

    In other news, even if the main engine does not work they may be able to approach the ISS using the smaller reactíon control system engines.

    Russia has vast experience with space stations. BTW, the US modules are built by Thales Alenia of Italy. Also the US Cygnus cargo vehicles for ISS supply. Also the US modules of the lunar gateway station. All made in Italy.

    But Roskosmos has gone downhill since the time Nauka was designed. If this fails, it would be another nail in their coffin. Russia is on the way out.

    Seems the engine tests were successful. Maybe a few days delay but good chance Nauka will reach the ISS and dock.

    First there were reports that the orbit has changed, it moved up a bit. Then from Roskosmos that the firing was good.

    Why would they choose to stop the 3rd stage engine and add a potential catastrophic procedure, (stopping the engine, it cooling down, starting the fuel supply and igniting it a second time), rather than just keep the engine burning, as during the initial lift off?

    Or is it a 4th engine?

    They seem to have put the solar panels and aerials out during the coasting phase, were any other essential procedures carried out?

    Are they required to navigate the new

    It apparently requires a number of orbits to catch-up with ISS.

    However, there are some ameristanis on board ISS, who may or may not, be sympathetic to ISIS.

    They don't want to use main propulsion to approach ISS, that's dangerous and not precise enough for normal launch vehicles. The Shuttle was different, it had sufficient small thrusters for the purpose. Nauka has its own propulsion module like all Soviet/Russian modules. US modules were brought up in the Shuttle, a different kind of operations.

    They intentionally chose a slow approach to the ISS. Nauka will take the place of the present Pirs module and they did not want to drop off Pirs before Nauka was in orbit and proven operational for ISS approach. All of this takes some time.

    No good and clear info from Roskosmos. Latest is it looks like the correction was with RCS only, not the main engine. It was a very small correction, though it helps to avoid early deorbit. They hope they can get the main engine operational but I have my doubts. We will see if they can get to the ISS with RCS only.

    No, it is a science lab. Will have people in it when attached to the ISS. Has another toilet, sleeping place and science equipment. Since Roskosmos has reduce their crew to 2 because they can not support 3 financially, these would not be needed, unless US astronauts use them.

    A bit of background. From memory only.

    Nauka should have launched many years ago. Then there were problems found. Saw dust in the tanks or fuel lines. Extended attempts of cleaning failed. A lot of things were completely rebuilt. Now the fuel systen has failed in orbit. Something went wrong with rebuilding and checking.

    Next is just my opinion. Roskosmos is not releasing clear information. They gave the impression they would test the main engine. Maybe they did, maybe not. Quite clearly the main engine was not involved in the maneuver. So it was not tested or it failed.

    For the time being the Pirs module is not going to be released. Which means they are not confident they will get Nauka to the ISS.

    If they lose Nauka it is a desaster for Roskosmos. Almost worse in its effect than losing a crew on a Soyuz mission in its effect on Roskosmos. Still glad, no people involved, of course.

    At least with "Spaceforce" the Americans might be able to steal the same amount of tech off those private companies as the Chinese do.

    things look a lot better for Nauka. They seem to have solved a number of problems. Pirs has vacated the port where Nauka is going to attach and will be deorbited by a progress cargo ship. The orbit of Nauka has been raised a lot already. So they got the propulsion working.

    A screengrab from my dual screen setup.

    Japan successfully tests rocket engine propelled by new technology | The Japan Times

    Japan successfully tests rocket engine propelled by new technology

    Japan on Tuesday successfully tested a rocket engine that was propelled by new technology using shock waves produced by burning a mixture of methane and oxygen gases, with the aim of applying the propulsion method to deep space exploration in the future, the country’s space agency said.

    The No. 31 vehicle of the S-520 sounding rocket series, measuring 8 meters in length and 52 centimeters in diameter and carrying the engine, lifted off from the Uchinoura Space Center in Kagoshima Prefecture at around 5:30 a.m., according to the Japan Aerospace Exploration Agency.


    It reached an altitude of 235 kilometers four minutes and four seconds after the launch and landed in the sea southeast of Uchinoura about eight minutes later, with JAXA retrieving a capsule containing test data in nearby waters.


    JAXA is currently developing technology that will allow it to utilize a rocket engine just one-10th of the current size that can also stay in space for extended periods.


    Jiro Kasahara, a Nagoya University professor, jointly developing the technology with JAXA, said the test demonstrated that the engine maintained a propelling force in space as expected.


    “We will aim to put the technology into practical use in about five years,” he said.


    “I’m glad the rocket was launched safely,” said Shinsuke Takeuchi, an associate professor at JAXA, who was leading the test launch. He added the test results are expected to be reflected in future academic achievements.
    Space News thread-np_file_101854-310x466-jpeg


    I had heard about the technology used for a long time from Russian sources who have claimed to build rocket engines with that technology for many years. But the claims they made about the efficiency of the system were ludicrous and I dismissed them for that reason. They also never showed anything operational and never built a rocket driven by it. The claims by the japanese developers make sense and they have built and demonstrated a working system in flight. These engines are a lot lighter and simpler than present engines. They did not make claims about efficiency in form of ISP.

    I am looking forward to future developments. Both in engine ISP values and how it scales to larger rocket engines. This one was only a small sounding rocket, but sure an impressive one.

    .

    Nauka is expected at the ISS today.

    When is the docking and how can I watch it?
    The new Russian module is scheduled to arrive at the space station on Thursday around 9:25 a.m. Eastern time.


    NASA TV will stream live coverage at 8:30 a.m. Eastern time. Viewers who want to watch the operation in Russian can tune into the YouTube page of Roscosmos, the Russian space agency.
