Turkey and Russia are in an advaced stage of negotiations to finalize a potential deal on Su-35. A supposed deal will be Turkey's second major purchase of weapon systems for Russia. The Turkish offials said that although the final numbers may change during the negotiating process, Turkey could by 2 squadrong (a batch of 48) Su-35s.

Why not negotiate for Russia's supposedly 5th gen fighter Su-57 that Putin is so eager to sell to Turkey? That's odd.

Putin's objective is not to arm Turkey; it is to entice them enough to get kicked out of NATO.

Turkey is the second-largest military force in the NATO alliance & is instrumental in establishing the alliance's hold in the Mediterranean. Greece was always seen as a country that was on the fence when it came to its loyalties vis-a-vis Russia, while pre-Erdogan Turkey was seen as a staunch, reliable ally. Even in Afghanistan, the US has sought extensive Turkish military assistance to 'connect' with locals, since Afghanistan has a similar identity crisis like Pakistan, though not at as alarming a level.

If Putin plays his cards well, he might actually weaken the NATO stranglehold in the Mediterranean, after securing the Black Sea. However, the Black Sea on its own means squat as long as the Bosphorus is under NATO thumb through the Turks. A non-aligned Turkey, on the other hand, is the ideal scenario, whereby it is not strong enough to fight Russia, and at the same time, can easily be won over with ceremonial platitudes.

The Su-57 is the pinnacle of Russian aerospace technology; I doubt he would want to sell it to someone who is still in NATO. S-400s were sold to widen the rift between Uncle Sam & Sultan Erdogan. Su-35s are a safer bet to be the final drop of ink on the NATO-Turkey divorce paper.

Roscosmos chief Dmitry Rogozin says that Russia wants to send its own mission to Venus, in addition to an already-proposed joint venture with the United States called "Venera-D." "We think that Venus is a Russian planet, so we shouldn't lag behind," Rogozin, a former deputy prime minister, told reporters on Tuesday. He noted that the Soviet Union was "the first and the only one" to land a spacecraft on Venus. It would be compelling to see the results of increased interest in Venus now. Diverse approach for the missions:
DAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging). VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy).

Actually, it sounds hilarrious to hear that. Russian space agency is so weak that it makes less launches than Space X per year. I don`t even mention about the space technology they have and how obsolete it is. And now they are claiming that Russia wants to send its own mission to Venus

Scientists from the South Ural State University (SUSU) have tested a demonstrator of a new rocket engine powered by an oxygen-hydrogen pair.

On October 7, 2022, a successful demonstration launch of a rocket engine based on oxygen-hydrogen components took place at the site of JSC "Research Institute of Mechanical Engineering" in the city of Nizhnyaya Salda, Sverdlovsk Region. Work on the project to create a reusable rocket propulsion system with a central body is carried out under the program of the national project "Science and Universities," the ANO "Regional Infrastructure of Education and Science" reported. At the site of the Scientific Research Institute of Mechanical Engineering, demonstration launches of a propulsion system with a central body were made, consisting of 16 rocket engines, which are combined into a single system. The rocket and space complex demonstrator for the returnable reusable launch vehicle includes control and monitoring systems with artificial intelligence and has no analogues in the world. This year, after a large amount of theoretical and design work, the demonstrator of the first stage engine was successfully tested on the oxygen-hydrogen fuel pair, which provides the maximum energy performance for the launch vehicle.

This is a big and exciting step in our project, because the oxygen-hydrogen fuel pair is a very explosive mixture, few people in the world know how to work with such engines: Russia, the USA and China {Big_Gazza edit: and India}. Now we are moving to a new stage, only this fuel pair will ensure the fulfillment of all the tasks. Therefore, we initially set the task of switching to oxygen and hydrogen, there were many doubts, because it is very difficult. Not everything worked out right away, but the launch took place, the central body, cooled, has already worked. Without exaggeration, this is world class. There is not a single scientific publication that would describe the launch of an engine demonstrator with a cooled central body running on oxygen and hydrogen, so we can say that these two launches, which took place, are the first in the world. The challenges we face now”, says Sergey Vaulin , SUSU Vice-Rector for Scientific and Educational Centers and Complexes.

Work on the project is supported by the Governor of the Chelyabinsk region Alexei Teksler . The regional government allocated 50 million rubles, another 5 million were sent by South Ural State University and 10 million by the Ural REC. The project is being implemented jointly with the State Rocket Center named after Academician V.P. Makeev (Miass), JSC Research Institute of Mechanical Engineering (Nizhnyaya Salda).

The demonstrator of a liquid-propellant rocket engine with a central body is similar to that which will be used in a promising reusable launch vehicle, which is being created today at the State Rocket Center named after V.P. Makeev. It is ten times smaller than a real engine ,” said Vladimir Degtyar, Director General and General Designer of the State Rocket Center named after V.P. Makeev, Academician of the Russian Academy of Sciences.

Work on the carrier rocket "CROWN" Since the 90s of the XX century, the SRC has been conducting initiative design work on a reusable single-stage vertical take-off and landing launch vehicle KORONA (Space Orbital Rocket - Single-stage Spacecraft Carrier). All LV engines use oxygen/hydrogen components. Most KORONA launcher systems are designed as modular. The launch vehicle provides for a high degree of autonomy in the performance of a flight mission, up to the independent completion of the flight in the event of a loss of communication with the control center. The design life of the design of the launch vehicle elements, most of its instruments and units is at least 100 flights, the OM and SOPP engines are at least 50, individual, especially energy-intensive units are at least 25.

Further on the aerospike demonstrator, here is the 2021 public trial (apparently using low flow rates of hydrocarbon fuel ?) compared to this recent test with hydrolox propellents.

Huge difference. Those are some robust propellent lines.

The development will be able to reduce the cost and availability of Russian launches. Roscosmos State Corporation has placed a preliminary order for the development of technical requirements for the parachute system of the return stage of space rockets. The development of the system, which in the future will help to compete with reusable rockets Rocket Lab and SpaceX, will be engaged in the holding "Thermodynamics" (part of the state corporation "Rostec"). Return of the rocket stage Rocket Lab Electron by parachute. Photo: Rocket Lab. According to the general director of "Thermodynamics" Igor Nasenkov, a pre-order from Roscosmos was received last month. This year they plan to start research work. At the same time, the timing of the creation of the system is still unknown, Nasenkov emphasized. "Eagle" and "Amur" The parameters of the parachute system for rockets are unknown, but their scale can be assumed using a similar system for a spacecraft. So, Igor Nasenkov told about the features of the parachute system for the promising spacecraft "Eagle". The system will receive three domes with an area of 1200 square meters. m each. This will allow the system to ensure the descent of cargo weighing up to 9535 kg. Now Technodinamika is working on prototypes of parachutes, and complex tests are planned for 2023. Testing will continue by dropping a full-size capsule from space, Igor Nasenkov added. Parachute system PBS-950. Such landing systems can become a reserve for the creation of return stages of missiles. Photo: Russian Defense Ministry Recall that in Russia since 2013, a reusable carrier rocket "Amur" has been developed. It is planned that in a reusable version, a rocket with a launch weight of 360 tons will be able to carry up to 10.5 tons to low Earth orbit (LEO). For comparison, the Soyuz-2.1b rocket can take only 8.2 tons for LEO. Amur will also receive an automated launch preparation system. All this will make launches cheaper. The estimated cost of launching a reusable Amur rocket (excluding the upper stage) will be $ 22 million - against about $ 45 million in which the launch of Soyuz-2.1b costs. The development of a reusable rocket will allow Roscosmos to reduce the cost of launch, which can attract new customers, and strengthen its position before private companies developing reusable rockets. Theory and example There are several systems that provide a soft landing of the first stage. So, on Falcon rockets, a complex complex is used, including three brake engines, rudders, a navigation system, and an orientation system. This provides an accurate landing, but significantly reduces the mass of the rocket's payload. Another example is the hard-wing return system (Energia-2), developed in the late 1980s by Soviet engineers. On the one hand, this would allow the stage to land at any airfield, and on the other hand, such a system also gives the rocket an excess share of additional weight. In 2001, a mock-up of the reusable accelerator of the first stage of the Angara rocket was shown. Model of the apparatus "Baikal" on which alternative ways of returning the stage were worked out But there are solutions that do not take the expensive mass of the rocket. These are air pick-up systems, and parachute landing. In the first case, you also need a parachute of a small area. Its goal is to reduce the speed for picking up the device by helicopter. Last year, the rocket Lab Electron rocket stage was returned in this way. In turn, a full-fledged parachute landing requires large-area systems to absorb the impact from landing. The development of synthetic fabrics made it possible to reduce the mass of large parachutes, which made it possible to create heavy-duty systems. For example, the military system PS-950 can "land" up to 13 tons of cargo, while the share of the system itself will be only about 12%. This allows you to take more cargo into orbit, while maintaining the possibility of reuse. However, this method requires an extensive platform of alienation, because such a landing system is uncontrollable.

Russian scientists have proposed sending a helicopter to Venus.

Scientists of The Moscow Aviation Institute offers to send an unmanned helicopter to Venus to research its surface and volcanoes.

In the spring, the Korolyov's Cosmonautics Readings opened in Moscow. The day before, a collection of abstracts based on the results of the readings was published.

"As a result of the development of aviation technologies, unmanned aerial vehicles are becoming more widely used. Currently, their application is being considered as part of the lander of interplanetary stations for research missions on the surface and inside the calderas of Venus ' volcanoes," one of the theses says.

The helicopter will have the shape of a sphere, the materials say.

Researchers note that the main problem in the development of Venus is the high temperature (467°C). In this regard, in the helicopter, the outer titanium layer with a diameter of 700 mm will have a wall thickness of 2.5 mm and is covered with screen-vacuum insulation-a material that is used for a large temperature difference between the insulated system and the environment.

In addition, it is planned to use aerogel, which has the lowest thermal conductivity.

Russia has tested a record-breaking long-running rocket engine - ВПК.name (vpk.name)

Russia has tested a rocket engine that can run for more than three thousand seconds (50 minutes), making it a record-breaking long-running engine. This is reported by TASS .

When compared with other products, it works almost 10 times more efficiently, since a conventional third-stage rocket engine usually runs for about 280 seconds.


"We conducted such a long test, and the engine worked not only for 750 seconds per launch, but worked for more than three thousand seconds, "said Viktor Gorokhov, chief designer of JSC" KB Khimavtomatiki".

He also stressed that the new oxygen-kerosene engine is the most economical, as it is arranged according to a closed circuit.

Earlier it was reported that the US Navy conducted the first fire tests of a solid-fuel engine designed for hypersonic missiles. In May, Popular Mechanics magazine wrote that the LRHW, launched from London, is capable of hitting Moscow during a military conflict.


Roscosmos Starts Preparations for Landing First Russian Cosmonaut on Moon, 23/09/2021.

MOSCOW (Sputnik) - The Russian State Space Corporation Roscosmos has launched a tender to study problematic issues related to organising manned Moon flights, requirements for space equipment for the manned missions should be developed, according to Roscosmos' materials published on the state procurement website.

"Objectives of the research work: development of proposals, recommendations and requirements for prospective technologies, elements and systems of rocket and space technology products that ensure reliable implementation of manned Moon flights and cosmonauts' work in lunar orbit and on the Moon surface," the document read.

The contract value totals 1.7 billion rubles ($23.3 million).

For the first time ever, Roscosmos indicated in an official document that the Angara rocket will be used for the first manned Moon flights.

The document also provides for the development of requirements for a small lunar take-off and landing vehicle, for the design of a new spacesuit and creation of an experimental model, for development of a super-heavy rocket and a manned transport vehicle.

The first results should be presented by the end of 2022, while the entire program should be finalized by mid-November 2025.

Also on Thursday, Roscosmos placed a tender to develop the requirements for a new space station, the Russian Orbital Service Station (ROSS), which is planned to replace the International Space Station (ISS), according to the state procurement website.

The development will be conducted within the scope of an "applied study into the problematic issues of implementation of manned Moon missions, creation of key elements and technologies including medical-biological ones, enabling cosmonauts to safely stay and work in lunar orbit and on the Moon surface in the part of work for 2022-2025."

The materials published imply, that the tactical and technical projects specifications for the ROSS and its seven modules are expected to be designed for as much as 1.735 billion rubles ($23.85 million). The research will be conducted till November 2025.

Russia plans to complete the operation of the Russian segment of the ISS and construct a new national station instead. The station is not going to be a habitation module, but crews of two to four cosmonauts will come there periodically. The launches to the ROSS will be carried out the Vostochny spaceport in the Russian Far East and the Baikonur Cosmodrome in Kazakhstan.

The Russian Ministry of Defense has published the appearance and technical characteristics of the new Russian ultralight launch vehicle Irkut for space purposes. This became known on Saturday, October 9th.

It is planned to launch it from the Plesetsk cosmodrome in the Arkhangelsk region in 2024. This was reported by the head of the cosmodrome Nikolai Bashlyaev, his deputy Alexei Nikolaev, the cosmodrome researcher Vadim Duga and the head of the department of the Mozhaisky Military Space Academy Dmitry Mosin.

“On the issue of the development of domestic ultralight launch vehicles, it is worth mentioning the project developed by the specialists of TsNIIMash to create an ultralight launch vehicle of the Irkut class,” says the article “Space Engineering and Technology” of the scientific journal of the Energia rocket and space corporation.

Additionally, the article notes that the rocket will exist in two versions: one-time and reusable. The weight of the first option will be 23.6 tons, the second - 25 tons. The first type will deliver 584 kg of cargo to near-earth orbit, while 84 kg to geostationary orbit. As for the reusable option, the weight of the supplied cargo is estimated at 398 kg and 60 kg, respectively.

The oxygen-methane vapor in the rocket will be used as fuel, and heptyl with amyl will be used in the upper stage.

Samara students test stabilization system prototype for picosatellites
According to specialists, it is quite difficult to develop a system for such spacecraft due to its limited mass from 100 grams to 1 kilogram

SAMARA, November 2. /TASS/. Students of Samara National Research University (Samara University) have developed and tested a prototype stabilization system for picosatellites - spacecraft with a mass between 100 grams and 1 kg, the university's press service told TASS. The design was found to stabilize the orientation of the vehicles in flight.
"After the rocket has taken the picosatellite to the target altitude, a sensor is triggered and a miniature electric motor with a flywheel on the axis is launched inside the spacecraft for one minute at a certain rate of rotation. This provides uniaxial stabilization of the satellite in space so that it is less wobbly in flight and so that it can, for example, take a video or photo, as it did during these tests, and get sharper, smoother footage. That is, stabilization is obtained by creating torque of spinning weight, like in a bicycle wheel - the faster you ride a bicycle, the easier it is to keep your balance. The tests showed that this idea turned out to be quite viable for a pico-satellite," said Alexei Kumarin, head of the Cosmic Gradient Club of the Korolev University of Samara.
The atmospheric tests were held during the Space Gradient launch campaign on the territory of university's yacht club on the Volga island of Proran. A total of three homemade experimental rockets were launched into the sky, which took three pico-satellites assembled by club members to a hundred-meter altitude into the Earth's atmosphere.
Without a system of orientation and stabilization the satellites would not be able to perform their tasks - to monitor the Earth's surface, to transmit and retransmit signals. The university noted that an effective system for orientation and stabilization of a pico-satellite is quite difficult because of its limited size. For this purpose it is necessary to fit various sensors, systems and payloads into a case the size of a can. Students from Samara have so far developed a stabilization system that helps keep the hull stable along one axis during the flight.

One of the students at the Institute of Aviation and Aerospace Engineering at Samara University, Polina Yakovleva, created three rockets from scratch for the launch, as well as a launcher, an initiating console for remote fuse ignition, and successfully conducted test launches. "The rocket launches at the Intensive were a very demanding endeavor, because without the rockets, the satellites would not fly. Modeling the rockets, building them and building the launch equipment started back in the summer and lasted until mid-October. For me as a member of the launch team, the launches themselves were very exciting: the results of the entire intensive depended on our work. And we managed to do it: none of the participants' vehicles crashed," the press service quotes Yakovleva as saying.

Russia is creating a super-powerful plasma rocket engine that will allow you to fly to the borders of the solar system (ixbt.com)

Russia is developing a new heavy-duty rocket engine that will ensure the flights of spacecraft into deep space. This was announced by the director of the Kaliningrad enterprise OKB "Fakel" (part of Roscosmos) Gennady Abramenkov.

«OKB Fakel, under the scientific leadership of the Kurchatov Institute Research Center, is developing a very high-power electric rocket engine, the so-called BPRD [Electrodeless Plasma Rocket Engine]. It will need a nuclear power source. Its tasks will include interplanetary flights, and in the future - flights to the edge of the solar system, "said Abramenkov.

«The entire central channel [of the engine], if it is not protected in any way, will either burn out quickly or the whole will be "eaten up". The walls must be effectively cooled and inside the central channel create such a magnetic field density that the plasma goes without touching the walls, "he added.

When there will be at least a demonstrator of such an engine, it is not reported. But, as Gennady Abramenkov noted, this will take a lot of time, since the engine will use physical principles with which the company's engineers did not work before.

MOSCOW, December 10 – RIA Novosti. Immersion of the crew of the Martian mission in artificial sleep would facilitate the interplanetary spacecraft by 50-70%, said Yuri Bubeev, deputy director for research at the Institute of Medical and Biological Problems (IBMP) of the Russian Academy of Sciences.
"According to preliminary estimates, the periodic "shutdown" of the crew will reduce the total mass of the ship by 50-70%, reduce the flight time, provide more reliable protection against radiation, due to the slowdown in metabolism," Bubeev said.
According to him, artificial sleep would allow during the expedition, "for example, to Mars and back" to refuse to provide the crew with tons of cargo for about a year and a half.

Earlier it was reported that "Roscosmos" and IBMP have entered into an agreement according to which by 2025 the possibilities of immersing astronauts in artificial sleep during flights to other planets will be studied. In the course of this work, as the director general of the Institute said in an interview with RIA Novosti, it was planned to study "psychotechnologies that induce altered states practiced in the traditional cultures of the peoples of Asia."
