Russia is only ~half of the former USSR.


Also looking at that chart, chained GDP is useless for countries who fake data like the soviets did. There is a 0% chance the Russian economy grew by ~40% from 1980-1989.... It would have been giving the Japanese at the height of their bubble a run for their money.

And Russia, don't have half of the problems, that have the old USSR...for example with all the materials, cars,  food, etc, they sent to Czechoslovakia, Poland, Hungary, Cuba, for they be happy with the socialism... etc...and other poor countries they must to support too like Kyrgyzstan , albania, etc, in that time  ...

And if you say the graphic, is wrong, in the 80 for the USSR (and they build the Energia-Buran), more impress it's the momentum of the GDP of Russia today, of course they can build a HLVs...

By they way the Russia economic is growth, right now, and in the next 6 years, can growth a lot more, with the energy price recovery and other industry like the cars and military industry...

Off course, Russia maybe never will have the power of the USSR...but still is a big country with rich minerals, oil, gas, a potent industry, that can recover a lot from the communism era in the next decades...

A little note please: Albania not cooperated with USSR from begin of 60' s. Albania in this time was a chinese area of activity. In other questions has 'Skrat' truth. It was a big theft.

Just a small remark from the former Czechoslovakia - Russia (or former Soviet Union)
This "or" is a common mistake made when the question of who benefited from whom is considered. The debts (if any) were made by the Soviet Union as a whole. Modern Russia is what was the RSFSR, the republic that was an object of the Soviet politics. The huge areas of land of enormous proportions went here and there on the scratch of a pen, the space industry was dispersed all over the republics, something that could not have happened today. If not for the USSR, you would have never heard of the country of Kazakhstan which owned 2 Energia HLVs after the dissolution of the Soviet Union, and to which Russia paid for Baikonur cosmodrom. So it is a much more complicated matter than "Russia exploited us".

I really don't understand what's your point. The guy i replied to was suggesting that Russia today has less problems than Soviet union, because it doesn't have to feed their satellites. I just pointed out that at least in case of Czechoslovakia, we were feeding Soviets and not vice versa.

I understand that people form Russia don't like to hear that but that's the fact. I used the relation between Russia and former Soviet union because even your people are often making this simplification, and correct me if I'm wrong, Russia is officially a successor state of the former USSR. Moreover, RSFSR was always the major driving force in USSR.

In light of what has made USSR to Czechoslovakia, I really don't care about the Baikonur. If it was meant that we should be happy for what Soviets have done to us, because we have supported Soviet cosmic program, than you must be crazy. Russia exploited us. That is the fact, it is not complicated, it is very simple. And when our people tried to change the course of events just a little bit, Soviets immediately started occupation. It lasted long 23 years from 1968 till 1991.

Does anyone know what Russia spends on their space program vs their GDP?  That would tell a difference.  From the outside looking in, it seems they spend a far bigger percentage on the military vs their GDP.  We as Americans spend far more on the military and social programs than the space program.  I wish all would cut back on the military and spend more on space colonization, and don't give and sell weapons to third world countries.  Spend it on heavy lifters.  Reusable if possible.

I'm not sure if Putin releases that type of information, and since their cost of living is far different than here in the U.S., and their economy is predominately tied to one commodity (i.e. petroleum) I'm not sure if such a comparison would be meaningful. Plus, the innovation in launch capabilities in the U.S. today is coming from the private sector, not the U.S. Government.

Plus anything that can shoot things to space has a dual use with the military, so not sure we can separate Russian peaceful rocket development from their military.

Depends on what the goals are, and even for the U.S. Government reusability had not been a priority. Though that had been because the private sector that was making money off of the government had no incentives to lower the cost to access space, so we'll have to see if saving money in the long-run is a priority for Putin.
If we don't continuously lower the cost to access space, how are we ever going to afford to expand humanity out into space?

Google says the Russian Space Program is R169.8B. GDP is R24,553.5B. So that is 0.69% of their budget, compared to 0.5% for NASA (excluding the military space budget).

Czechoslovakia, East Germany and Hungary are the exceptions, because they were all rich countries, before the WWII, and the USSR "anexion" like her satellites ...but all the other countries incluying Cuba, were a feeding countries from mother Russia, that is other fact...

In 2017, Roscosmos State Corporation provided for budget allocations in the amount of 233,612 million rubles (= $ 4 billion) ... GDP of the Russian Federation (2016) $ 1585 billion. 0.25% of GDP.
Plus, part of the military programs is funded under the MO budget. The amount is unknown.
In 2016.

With 26 nozzles at say 2 MN each, that gives a liftoff thrust of 52 MN! If this can put say 20 t into low Lunar orbit (LLO), then a standard dual launch Lunar orbit rendezvous  (LOR) mission could be achieved. First launch delivers a hyperbolic lander into LLO. Second launch delivers Federatsiya into LLO, which rendezvous with the lander. Standard Apollo mission architecture then follows. NASA could do the same with SLS Block IB, but they are stuck with their complicated Gateway plan.

If they use Soyuz, staged Lunar descent with a lightweight lander and propellant transfer between the kerolox cores, they could probably do a Lunar mission in a single launch.

1. Pass propellant from four outer cores to all the engines and then eject the four empty cores.
2. Pass propellant from the two remaining outer cores to all the engines and then eject the two empty cores.
3. Full centre core then completes its burn.

Roscosmos has published technical specifications for the Yenisei heavy-lift launch vehicle.

https://zakupki.gov.ru/epz/order/notice/ok504/view/documents.html?regNumber=0995000000220000063&backUrl=e143c676-d0fd-4c7a-a5ac-b19d671a4f69

This marks the beginning of the second stage of the project (the so-called “technical design” or TP), which follows the completion of the “draft design” (EP). The project officially began with a government contract signed on April 2, 2018 and is being carried out under the name “Elementy STK” (STK standing for “super heavy class”). The “TP” stage of the project is to be completed by November 15, 2021. It is essentially aimed at further refining the design of the rocket and lays the groundwork for producing detailed blueprints and building the actual hardware.

Here is a quick summary of the most important information given in the documentation.

The complete “rocket and space system” (that is the rocket and the cosmodrome infrastructure needed to prepare it for launch) is designated 371KK443. The heavy-lift rocket itself is referred to as 372RN31 (the name Yenisei is not mentioned) and consists of:

- six strap-on boosters with LOX/kerosene RD-171 MV engines (unified to the maximum extent possible with the first stage of the Soyuz-5 rocket)
- a core stage with a LOX/kerosene RD-180MV engines
- an acceleration/braking stage with two LOX/kerosene 11D58M engines (Blok-DM type)

The possibility is to be studied of adding an extra upper stage with two LOX/LH2 RD-0150 engines (from the Angara-A5V) to increase the payload capacity. Piloted missions will carry a launch escape system designated 374SA11. The launch pad will also be able to support launches of the Soyuz-5.

The main payloads for the rocket will be the Piloted Transport Vehicle (PTK or 372PE01) (the name Oryol is not mentioned), the Lunar Take-off and Landing Complex (LVPK) (a crewed lander)  and the Lunar Cargo Landing Complex (LGPK) (an unmanned lander). Also mentioned is “the launch of automatic satellites and modules of new-generation space stations into Earth orbit, to the Moon, Mars, Jupiter and other bodies in the Solar System”.

The types of orbits given are:
- 51.7° : 330 to 430 km and 800 to 1000 km
- geostationary orbit
- geostationary transfer orbit (with a delta-V of 1500 m/s to reach GTO)
- escape trajectories to Venus, Mars, Jupiter and Saturn

The rocket is capable of placing a PTK with a mass of at least 22 tons and an LVPK or LGPK with a mass of at least 27 tons into a polar lunar orbit at an altitude of 200 km.  The LVPK and LGPK will first fly to the L2 Lagrange point using the Blok-D type acceleration/braking stage, after which it will take them about 100 days to reach lunar orbit, with course corrections and lunar orbit insertion being carried out with the help of their own propulsion system. For piloted lunar expeditions, a dual-launch profile will be used, with two separate rockets being used for the launch of the PTK and the LVPK. The preliminary plan is to fly lunar landing missions of at least 14 days with a crew of four.

The launch infrastructure at Vostochnyy should be able to support  at least two launches per year from a single pad, but the possibility is to be studied of increasing the launch rate to six per year. The minimum interval between two launches should be 90 days. Launch preparation time shouldn’t exceed 56 days.

The first test flight is scheduled for 2028.

From the latest issue of "Russkiy kosmos": drawing of a mobile launch platform for Russia's new heavy lift launch vehicle at Vostochnyy. This is a radical departure from the horizontal transportation method used by the Russians so far, even for their earlier heavy lift launch vehicles (N-1 and Energiya). Would require the construction of a VAB type assembly building.

What's with the upper fairing enclosure swung to the side though? It looks like it would be for a manned capsule, but when would that happen, aside from some large single launch lunar architecture with a enormous upper stage...

Yensei is what is shown and Don uses the top hardware as its the tallest version of the joint HLV/SHLV architecture.

Don is supposed to have a big LOX/LH2 upper stage. Attached is a drawing showing an early concept for  Yenisei and the larger Don.

Incidentally, recent Russian press reports suggest the design of the heavy-lift launch vehicle is again being revised, with the possibility being studied of using LOX/methane on the first stage.

MetaLox forever! ;D
https://ria.ru/20210302/raketa-1599529588.html

So they would be ditching the RD-171 and its derivatives? That would be quite shocking and sad!  :'(

Didn't they decide that once Soyuz 5 is up and running they will use a cluster of Soyuz 5 cores to come up with the HLV design?
