    Past failures had clear signatures of sabotage. Not all of them, but enough to raise questions about how many. This is like with the
    Bulava SLBM. The problems went away after the nest of US spies near the manufacturing plant was removed. There are always
    losers will to sell themselves for 30 pieces of silver.

    Of course, there is not going to ever be a zero accident rate, but at least we see that it is much lower than what it was supposedly
    before.

    NPO Energomash assembled the second flight engine RD-171MV

    At the end of autumn, NPO Energomash (part of the Roscosmos State Corporation) assembled the second flight sample of the RD-171MV engine for use in the first stage of the Soyuz-5 medium-class launch vehicle.

    Also in November, Energomash handed over to JSC RCC Progress work on the corresponding stage of development work. Currently, the assembly of the third flight model RD-171MV is being completed. The next stages of the program will be interdepartmental testing of the RD-171MV engine and serial production of engines for completing the Soyuz-5 launch vehicle.

    RD171MV is the world’s most powerful liquid-propellant rocket engine developed and produced by NPO Energomash JSC. RD-171MV is a modernized version of the RD-171M engine, which was developed in 2001 on the basis of the Soviet RD-170 engine. The RD-171MV uses kerosene and oxygen as fuel components, and its thrust is 800 tons.

    At the Angara Launch Complex, Vostochny, complex tests with the Angara-NZh ground liquid mock-up were completed

    At the Vostochny Space Center on the launch pad for the Angara heavy-class rockets, comprehensive tests with the Angara-NZh product were completed.

    Specialists from the enterprises of the Roscosmos State Corporation successfully carried out all the necessary checks as part of the first stage of testing. The temperature control system of the electric refueling mock-up operated normally, and electrical checks were successfully carried out. The calculation carried out partial and complete filling of the model with rocket fuel components  -  liquid oxygen and naphthyl. The refueling systems worked without any problems.

    After completing all operations with Angara-NZh and draining the rocket fuel components, the product was transferred to a horizontal position and transported to a technical position in the installation and testing complex.

    The Soyuz-2.1b rocket with the second satellite "Arktika-M" launched from the Baikonur Cosmodrome

    MOSCOW, December 16. /TASS/. Launch vehicle "Soyuz-2.1b" with the Fregat upper stage and the hydrometeorological satellite "Arktika-M" No. 2 launched from the Baikonur Cosmodrome. The broadcast is onwebsite of Roscosmos.

    Later, the head part of the rocket as part of the Fregat upper stage and the Arktika-M satellite successfully separated from the third stage. Injecting the spacecraft into the target orbit will take more than 4.5 hours.

    Hydrometeorological satellites "Arktika-M" created on the basis of the unified platform "Navigator" produced by NPO named after S. A. Lavochkin. The satellites will provide round-the-clock all-weather monitoring of the Earth's surface and the seas of the Arctic Ocean, as well as constant and reliable communications. In addition, the satellites are capable of relaying signals from radio beacons of the international search and rescue system COSPAS-SARSAT.

    The first such device was launched from the Baikonur Cosmodrome on February 28, 2021. Initially, it was planned that the space system would include two Arktika-M satellites, but in December 2022, the NPO named after S.A. Lavochkin announced that the constellation would be expanded to four satellites. The company added that this will reduce the frequency of filming by half. Fully deploy the Arktika-M grouping planned by 2031.

    The first image was received from the Arktika-M spacecraft No. 2

    The first image was taken from the Arktika-M No. 2 spacecraft.

    The satellite is designed to provide information support for monitoring the hydrometeorological and heliogeophysical situation in the Arctic region and adjacent territories, and relay signals from the COSPAS-SARSAT satellite search and rescue system.

    “Arktika-M” No. 2 is equipped with two MSU-GS-M, which back up each other - these are the main and most important target devices that allow continuous imaging of the Earth’s surface with a frequency of 15 to 30 minutes in ten spectral ranges (seven of them are infrared). The spatial resolution of the data ranges from 1 to 4 km, and the accuracy of measuring the temperature of the underlying surface reaches 0.1–0.2 °C.

    Another important part of Arktika-M is the on-board equipment of the command and measurement system (CIS). This is a radio system that ensures interaction between the satellite and ground control stations. It receives and processes command and program information from the Earth, transmits it to other systems and devices inside the device itself, and from them, in response, the CIS receives and transmits telemetry information via radio to ground stations. The system also transmits signals to ground stations to measure the current navigation parameters of the spacecraft.

    Two satellites of the Arktika-M space system (the first was launched on February 28, 2021), alternately replacing each other, provide consumers with data for round-the-clock monitoring of the Earth’s surface and the seas of the Arctic Ocean, relaying signals from emergency radio beacons of the international satellite search and rescue system COSPAS- SARSAT and information from automatic measuring platforms for data collection of Roshydromet, including those located in the Arctic region. Information received from satellites will allow Roshydromet departments and other departments to increase the reliability of long-term and short-term weather forecasts, help monitor emergency situations, carry out environmental monitoring of the environment, and provide scientists with a large amount of new data for studying global climate change.

    Journalists are a waste of space. The two Arktika-M satellites are in Molniya type highly elliptical orbits (HEO) with a 63.4 degree inclination
    and 12 hour period. So two of them give 24 hour coverage. HEO is a medium Earth orbit, so it is much closer to the surface than geostationary
    orbit typically used for weather satellites which is also confined to the equatorial plane (if you want locking on a single region in the field of view).

    It was a more modern and more advanced design than that. They had built mockups and everything. They lacked a launcher and launch site. Soyuz doesn't have enough power to lift it. But now there will be Angara at Vostochny.

    Info on current plans for developing the ROS station:

    The main milestones are the end of 2027, when the first scientific and energy module will be launched into orbit, and 2032, when the creation of the station in its basic configuration (six main modules) will be completed. In the first half of 2028, it is planned to launch the hub and gateway modules into orbit. They will be docked with the scientific and energy module, which will allow the first cosmonauts to fly to the station.

    I suspect that (for once) the US DoD was right and the Uragan was a real project, and was likely well down the detailed design and prototype fabrication path when it was cancelled (being a military spaceplane it has never been confirmed by post-Soviet authorities). If Russia decided it needed a spaceplane to service the ROS it makes some sense to dust off the pre-existing design and upgrade with modern materials, system and manufacturing techniques. Kliper was a nice design (the winged verison, not so much the original lifting body variant) but was never developed beyond conceptual design and mockup stage.

    The Uragan looks like viable mini-shuttle design. The Klipper has a much smaller lift surface area and looks dubious. It probably required a parachute landing and
    the lifting body design was more for slowing down the re-entry. The Uragan should be able to land on a runway.

    NPO Energomash is modernizing engines for the Angara launch vehicle

    The first test of the development engine took place on January 17

    MOSCOW, January 23. /TASS/. NPO Energomash is working to modernize engines for the Angara launch vehicle. This was announced by Deputy General Director - Chief Designer of NPO Energomash JSC Petr Levochkin at the plenary meeting of the XLVIII Academic Readings on Cosmonautics in memory of S.P. Korolev (“Royal Readings”).

    “A modernized version is currently being created, <...> a ten percent boost of the RD-191 engine will lead to a significant increase in the payload of the Angara launch vehicle. In 2023, autonomous tests were completed, the first development engine was manufactured, and <...> January 17 passed the first test of the first development engine, this evening we have the second,” Levochkin said.

    I wonder if SSTO vehicles could be scaled down, or simply modified to be, lighter and faster accelerating supplements to intermediate and intercontinental missiles. If their acceleration is superior to multi staged missiles they could give the enemy less time to react.

    ... they have done thr space stations dmanit. They need to next make a space station with just one to two nodes orbiting the moon and develop shuttle transfer from there. The mars race is retarded. If we can get enough critical infrastructure on the surface of the moon we can then burrow tunnels in ideal locations around the south pole and once we have underground facilities on the moon we can start talking about legit self reliance and construction using largely moon based infrastructure.

    Guys it would be vastly expensive but we absolutely could do this. If we got critical infrastructure on the moon imagine the possibilities. Screw mars. Think about moon and earth joint missions with nuclear tugs sending equipment, habitation, robotic vehicles and sensors and ultimately people to Ceres and the moons of Jupiter and beyond. The key is developing larger space stations and focusing on the moon.

    Why just another space station like the others? We need to step ahead.

    A foot-hold in LEO is essential however, and with the ISS approaching its end-of-life, it is vital that Russia develops a new station to replace their ISS assets. Direct ascent from Earth to the Moon as with Apollo is very inefficient and not a sustainable way to develop Earth-Lunar infrastucture. Develop ROS first, then lunar infrastructure, preferably in concert with China (even if Russia must be a junior partner if it cannot match the Chinese financial outlays). Consolidation of a co-operative relationship with China is also vital as it allows Russia to gain access to specialist Chinese services if required, eg SHLV for any super-heavy payloads that A-5Vs can't manage, and joint-venture projects. Imagine the Russian Zeus nuclear-electric propulsion system with a big injection of Chinese capital and human resources...

    To send three men to the moon with a little lander and rover they had to build the biggest rocket in history, it is just not practical to make the equivalent but scaled up to reach Mars or anything else in our solar system.

    To get to the moon takes a week or two or three to get there, do some stuff and come back. A trip to Mars is going to take years because even if you went there and came straight back that is going to be more than 12 months, but of course who would go there and do nothing but look and then come straight back?

    Flying there with robots and setting up bases with unmanned systems and using a nuclear powered tug system to fly there under power all the way there and all the way back will speed up transit times and actually make conditions in deep space more tolerable because with a nuclear powered ion engine or something similar at least you would have micro gravity creating some sense of normal where there is an up and a down.

    The real difference is that anyone going to Mars is on their own and there is a very good chance someone will die.

    Such things get people upset, but how many people die every year still trying to climb Mount Everest?

    I like the idea of space travel for people because it demands recycling and reuse... which is the opposite culture on earth thanks to the US and big business wanting to sell you something you don't need or want.

    The point I am trying to make is that we are going to need to build space ships in orbit... in space and they are going to take multiple rocket launches from earth to assemble them and once assembled they can be sent towards Mars or some other destination but when they reach their destination putting them in orbit of the object they are going to would be easier than landing them... so these space ships will also be space stations and you might send other landers and space stations before you send people just to set up a landing area and perhaps even start producing water which is rocket fuel and oxygen so by the time you send people there they have the resources to live for quite a period of time if needed so if there is a problem things can be sent to bring them home.

    3D printers on the small scale to make parts and on a huge scale to build shelters out of local rock material will make things more comfortable and safer, there are lots of technologies that need to be working well before we go.

    It is all fine to make resuable plastic containers for things only to get there and find they shatter and are fragile in minus 60 degree temperatures...

    Being able to get there in a reasonable time is the first problem to solve but there are countless other problems that also need to be solved like growing food and recycling human waste... all of which are technologies that would be useful here on earth.

    A 3D printer that uses plastics that cannot be recycled to make things that are useful and when no longer used can be broken down and 3D printed again into something else to be used would be as useful here on earth as on mars or in space.

    The Express-AM44 telecommunications spacecraft reaches 15-year milestone.  Launched February 11, 2009 it had a 10-year guaranteeed life.  Express-AM44 provides communications services ie digital television, telephony, videoconferencing, data transmission, the Internet access, presidential and governmental mobile communications.

    Comms package was suupplied that Thales on a Express bus by Reshetnev. Still operating but its primary role has now been taken since March 2021 by the new Express-103.

    Well done to Reshetnev.  So much for Russians being unable to build long-lived birds.

    "Unable" is the usual hater extrapolation from nothing into fantasy. The USSR did not bother to build unpressurized satellites (maybe they
    had some that were, but most were pressurized). They did not care about launching new ones after 7 years. Space (i.e. higher energy Van Allen belt
    electrons, the solar wind and high frequency EM radiation) wears down anything launched into orbit so may as well refresh equipment regularly. Now
    that Russia bothered to deploy unpressurized satellites (i.e. vacuum rated electronics, etc.) they have clearly done the job right. But haters cannot
    contain their bile and try to paint congenital inferiority in every crack.
