There are few good points tho. For example: >Our Soyuz MS has proven to be the world’s most reliable spacecraft. We have a unique record of 173 successful flights. Even the three emergencies caused by the carrier rocket failures in 1975, 1983 and 2018 occurring during various injection stages showed its unique survivability due to the launch escape system reliability. By the way, the Soyuz rocket of various configura…

They are planning for around 30 launches in 2020, and 50 in 2021

No they are not. Here the matter is crewed launches, and SpaceX isn't going to launch 30 manned Crew Dragons this year, or next year, or these two years together.

You can't even imagine. The whole east Russian speaking conglomerate of contries is basically a test to your human nature and survivalism.

Right people can’t begin to imagine why sanctions against Russia don’t work. Subtracting from near zero leaves them at near zero. Moar sanctions don’t bother them as they are already used to living with the bare minimum. It’s not like pulling the rug from under a middle class lifestyle or where people are on the cusp of success.

> Right people can’t begin to imagine why sanctions against Russia don’t work.

Because they are mostly token sanctions, to raise awareness - "you're doing something which we don't agree with". Some sanctions are also more targeted - like https://en.wikipedia.org/wiki/Magnitsky_Act, which is more troublesome for it's targets, at least judging by their reaction.

> Equally strange is the statement that 'for the first time a private company created a crewed spacecraft'. And what about Boeing and Lockheed Martin? Aren't they still private or have they been nationalized? SpaceX is no less a private company than Boeing is with the ties to the Pentagon being no weaker, ULA is a private rocket company, yes, and successful, but they don't yet have a successful crewed spacecraft.

The principal difference is the NASA involvement and its forms. For Mercury/Gemini/Apollo/Shuttle NASA designed, managed and ordered spacecrafts. For Crew Dragon, NASA buys launches - with a lot of say in how the spacecraft should be built and behaved, but still not on the level of project initiator, as it happened before.

SpaceX is a bigger author of its manned spacecraft than any private company ever was.

> The new American spacecraft are more than double the weight of a Soyuz while offering only one additional seat. Is this true? The launch mass of a Soyuz capsule is about 7000kg and the SpaceX Crew Dragon Demo-1 launch mass was about 12000kg so not "more than double" however Demo-1 didn't include astronauts. The Crew Dragon can theoretically carry several tonnes of cargo to the ISS in addition to 4 astronauts.

I don't know if that is true, but why does the weight of the rocket matter? A reusable rocket will be heavier as it has to be built to carry extra fuel for re-entry. I would still want a reusable Space X rocket even if it is heavier

The idea here, I think, is that Dragon requires a heavier rocket - Falcon-9 - that the Soyuz does. Soyuz flies on a rocket with payload around 7500 kg, while Dragon flies on a rocket with payload, according to Wikipedia, "15600 kg when landing". So it's either a heavier spacecraft or an under-use of a rocket.

Not that such use would be particularly bad - from a point of view of standartization of launchers, for example, or taking into account that F-9 has a reuseable first stage, it makes more sense. However by payload mass the Soyuz looks more optimal.

There are significant technology and financial sanctions too... but it’s like applying them to Yemen and thinking “that’ll hurt’em” or whatever, except worse because Russia has technical ability and they trade with China, etc. but like Yemen their people are used to austere circumstances.

Butthurt Russkie. Good thing that the Free World won't have to rely on these beasts for space travel anymore.

You don't really know; even in 1975 USSR and USA had a joint flight, and Cold War was in (almost) full swing at the time. Who knows, we're going to go to the Moon soon - and USA and Russia are two countries who have the most manned lunar experience so far - we could still need each other's support.

> the cost of our launches is substantially lower

Cost for a seat on Soyuz is $90MM, cost for a seat on Dragon is $55MM. These are the market rates, not the true cost. In that whole paragraph he's basically saying that the true cost of the seat on the Soyuz is still cheaper than the true cost of the seat on the Dragon. Is there any data to substantiate that? I suppose we'll see in the coming months and years if they actually reduce their asking price.

"America is a very large country, and a large country should be benevolent and noble" What? Is something lost in translation here? Interesting, Russian idiom perhaps?

Maybe a translation confusion of "big country" as in major country to "big country" as in large?

Sadly Russia culturally and technologically is not a successor to USSR. Its space program is in shambles. Soyuz was designed in the '60s and Russia's space program can't offer anything new. That happens when you pay your engineers 150$ per month(floor cleaner at McDonald's makes $250) while Rogozin gets 400k$ per year (that's only the official number...), double of what NASA director makes. Humanity needs a way to ac…

> Sadly Russia culturally and technologically is not a successor to USSR.

I think that's a very very good thing for all the atrocities that Soviet Russia committed on it's populace and especially the populace of the various Republics.
