That’s it, lecture finished. Didn't get to ask my question, unfortunately. Some more pictures:

Ok, found a free seat. There’s more press and TV crews here than students, lol Thales Alenia Space director is also here. 36.4% of Roscosmos income is from non-budget sources. 91 sats currently in orbit. “Sfera” LEO constellation is very important. New Glonass sats without imported components are to be launched in 2020. RD-180 is the best engine. RD-120 also very good. RD-171MV for moon rocket is ready for test fire. Current rockets: Angara-A5 launch this year. Up to 8 A5 launches every year from 2024. Very important to take the launch market back from SpaceX. ”Sarmat” heavy ICBM tests successful. 51% of all tram cars in Russia are made by Roscosmos from metal scraps from building rockets. Most of the money is not in launch market, but in sat building and operation market. Roscosmos will participate in “Smart city” and car autopilot programs (with sfera sats?). Autopiloted Roscosmos tram cars: “Canopus” sats helped with locating wildfires and unsanctioned logging. Future priorities: Recent launch failures because of human factor. Tech is good, humans are unreliable. Getting rid of non-core assets. Except tram cars. New Roscosmos bank will help stop rampant corruption and thefts. Can no longer sell Proton launches for 100 million because of SpaceX. Their pricing is dumping, anti-competitive and only aims to kick Roscosmos out of launch market. Will consolidate all research institutions into one science center. Vostochny is vital. Will eventually move all launches there. Launch pad for Angara A5 currently under construction. Launch pad for super heavy rocket next. Nice animations. Future rockets: Methane/LOX rocket (SPG), 9t to LEO Angara-A5M, 27t to LEO from Vostochny Angara-A5V with hydrolox upper stage, 37t to LEO. Moon tugs and stuff will launch on this one. Reusable “Federation” spacecraft for moon missions. Super Heavy (STK-1 and 2) kerbal-style rockets, up to 140t to LEO. Moon missions. NET 2028. Luna-25 lander in 2021 to south pole. Luna-Glob lander to test soft landing, also 2021. 2022 first “Federation” launch. 2023 launch to ISS. Many lunar sats to test various stuff for manned missions during 2021-2027. 2025 sample return. 2026-2028 unmanned “Federation” launches to the Moon. Will also send anthropomorphic robots with motion capture control. 2029-30 manned flights to lunar orbit. Aim to deliver foreign payloads to the Moon too. 2030 manned Moon landing. Base construction starting the same year. Luna-25 almost done. ExoMars lander “kazackok”. Rogozin wanted to name it “novichok”, but decided not to (lol). ”Bion” lander with animals to far side of moon (no ETA). Venus probe (also no ETA). “Fedor” avatar robots: These will work in dangerous environments, e.g. outside ISS. Fine motor control is good enough to draw paintings. New national space center in Moscow to be completed in 2022 for 50,000 employees. Angara production plant will be nearby. “Technopark” territory where international partners and space-related university departments can have their buildings. That’s it. There was much more, but I could only write this fast. Question about strategic mission of Roscosmos. Answer - expansion of Russian influence in solar system and creation of high-tech jobs. Question about corruption. How to deal with it. Answer - Rogozin was appointed director to end corruption. He started the investigations, they’re very productive. Media coverage not helpful and often misleading. Roscosmos is fighting corruption more than other state corporations. Most of subordinate directors replaced in 2019. Question about Falcon 9 and Angara. F9 launches for Pentagon are 3 times more expensive than commercial, hence dumping. Angara will be competitive even with F9. Question, is space political? Definitely yes. Relationship with NASA is remarkably good despite sanctions, but US Senate unhelpful. Question, how to deal with media attacks. Every failure is overblown in media, compared to other state corporations. Will have to just keep working despite the media. Space is hard. Promises new Roscosmos that we won’t recognize. Question, does Roscosmos need political scientists. Answer: he is afraid of political scientists. But seriously, they do. Heavily criticizes American lunar program for constantly switching goals and dates. He thinks that it’s a political battleground between Trump admin, Democrats and Republicans in various state institutions. Question, will Russia participate in LOP-G? Answer: new American plans to land on the Moon in 2024 make LOP-G pointless. Focus on our own programs. ISS is much more important. New ISS modules. Waiting for Americans to decide on their plans. Stupid question about Elon Musk meme. SpaceX is a good challenger, competition is ultimately good. Will work with S7 space to launch Soyuz-5 from Sea Launch, increases payload to 23-25t to LEO.

Yes, tanker flights are most strongly affected by this. 150t vs 100t to LEO means that 33% fewer tanker launches are needed to refuel a Starship.

At the altitude where stage sep happens, SL engines are hugely underexpanded, it’s a waste of efficiency. Payload mass will drop. I think 7 engine config (4 Vac + 3 SL) is the way to go.

3 vacuum Raptors generate thrust of about 5.7 MN. Fully fueled Starship is about 1100t.That gives a TWR of about 0.5 after booster separation. Isn’t that too low for manned flights? F9 S2 TWR is close to 1 at stage sep.

It should also bring LEO payload back to 150t.

Q: What is very large, makes a lot of smoke and noise, takes down 20 liters of gas per hour, and cuts an apple into three pieces? A: The Soviet machine built to cut apples into four pieces.

Counter argument: Elon Musk builds his new rockets in the field without even a barn.

So he is going to take questions. Good.

With “no end in sight” to fraud in Roscosmos (actual quote from top investigator), billions being funneled out, aging Soviet-era technologies, terrible pay and working conditions, top execs fleeing to other countries, notoriously bad quality control, future rockets that are already strictly inferior to foreign competitors and record-breaking failure rate on existing rockets - why do you think that this train wreck of a space agency can be fixed? (Well, maybe in a bit milder terms. Maybe.)

So it looks like the Trampoline Man himself is going to show up at my university with a lecture about how he’s going to fix Roscosmos. I might attend. Don’t think he’ll take any questions, though. But on the off chance he will, I’m going to ask a tough one

Also worth mentioning that in modern airliners most of the thrust comes not from combustion chamber exhaust, but from rotating fans driven by said exhaust through a set of turbines. Fans don’t need a nozzle because, as I understand it, there is little pressure difference between ambient air and turbofan exhaust.

I remember the NSF article stating that And then there’s that latest tweet by Elon. NSF changed their article after that, and now it doesn’t say anything about the “multiple sources” and their info about SSTO launches. So... why did NSF choose to publish unreliable information from some unknown sources? Not a good look.

Those cruise missiles are supposed to be used as a last resort in situations where public opinion is irrelevant and radioactive pollution of targeted territory is desirable. Not what you’d want during a regular orbital launch. ...also, I don’t think this nuclear jet cruise missile is real, but that’s another story.

“multiple sources”, though. I'll wait for official confirmation. How much dv does it need to pull it off? 10k? (Launch + landing) Theoretically possible with 10k m/s dV, Isp of 380s, 75t dry, 1100t wet mass.

They’re planning to have some sort of IVF-like system for these landers, right?

My favorite ridiculous name is TOS-1A “Solntsepyok” - “Sunburn” Heavy Flamethrower System. Sunburn! lol

Would be great if planets had surfaces that look like this...

Hmm, in that case, maybe they can convert the fuel tanks into habitable space? Cut the bulkheads, build floors, etc.

Pretty sure it was 1.0. Saw a youtuber LPing it, liked what I saw, grabbed it on Steam.

Good for raiding LOP-G and pillaging food and fuel from it! Remember that “Federatsia” needed a proper male name? I propose “Berserk”. Odin > Artemis.

Possibly. Orbital prototype is almost useless without it.

Fun fact. Chemist Valery Legasov was a professor and chair of the Division of Radiochemistry and Chemical Technology at the Chemistry Department of Moscow State University. I graduated at the same department of the same university and now work in the building next door to the division he was administrating. He is legendary here.

Kinda like in KSP. You build a thing, then build a rocket capable of getting the thing where it needs to be, name the entire stack “Mun Explorer” or so, and launch it. Both the rocket and its payload become parts of this “Mun Explorer” mission. Then you make another thing, load a “Mun Explorer”, take the rocket and add it to the new thing (I do it all the time). That’s how Soviet R-7 variants (Sputnik, Vostok, Voskhod, Soyuz, Molniya, etc) got their names.
