I'm trying to come up with a reusable 2MN class RP1/LOX engine.

Should I go for oxidizer-rich staged combustion, or tap-off cycle? Alternatively, if I used propane instead of RP1 I could use the expander cycle.

>>15672238
Has to be a GG. You can't disassemble a staged combustion preburner between flights to scrub the coke off and call it reusable.

The EU as an entity must essentially dissolve. The member states would need to pursue their own projects or renegotiate agreements between one another. That entire part of the world is insanely stagnant and burdened by regulation, and requires some kind of political calamity/cultural revolution to be competitive in something like spaceflight again. The concept of a frontier is just too foreign to current European governments.
The ESA is unsalvageable.

>>15672219
Neither

>>15672280
Euros have a future because they are allowed to buy Starship tickets. Other than making the occasional deep space satellite, they are basically just an extension of NASA that will service Europeans to get in to space.

ESA is fine and doing exactly what it should do: science missions that can't ever return a profit.
Rockets and spacecraft should be made by private companies, not state agencies. In that regard, it's not impossible for Europe to get better rockets but I don't see it happening anytime soon.

ESA needs to privatize and rapidly. Georeturn has it fighting with both hands tied behind its back. France will try to sabotage it every step of the way and will require an absolute army of lawyers to lasso into compliance. They might still just fuck off and do their own thing with CNES anyway once it becomes clear that they won't be getting much money back. Losing Guiana would mean finding a new launch site, likely in Kenya

As far as goals they're likely going to be the first to move on space solar, and they're going to have to figure out how to get that kind of upmass with whatever they end up picking as a launcher.

>>15672339
Kenya is well positioned geographically but is a bit of a mess politically. While they're not the mad max horror show their neighbors can be they've had a lot of issues with corruption and extrajudicial killings of late. If France had to find a new launch site (and it seems very weird they'd lose a site that's located in sovereign French territory) cutting a deal with Brazil for use of the Alcântara Space Center would seem more likely. France has ties to the Brazilian space program that go back to the 1980s and they wouldn't need to start building the spaceport from scratch.

European space is doomed. The ESA is culturally worse than Boeing. All their projects are jobs programs first, and science missions second. They take no risks, and they're literally decades behind the state-of-the-art (and only getting further behind.) In a word, European space is...

>HIDEBOUND: /ˈhīdˌbound/
>adjective
>unwilling or unable to change because of tradition or convention.

Europe has no concept of innovation. Given that the EU is roughly the same population and wealth as the US, it's crazy how little new stuff they actually build. For example, there are virtually no tech companies in Europe. So all the best and brightest Europeans end up in America because the opportunities are here and the pay is much better. This siphoning off of the top X% of EU talent means they're perpetually working with mid-tier people. In innovation/tech/startups, you simply cannot DO anything without really brilliant people. The pareto principle (20% of the people do 80% of the work) is probably even more extreme at the very technical/hard industries like tech and space.

Business idea: Farming, in space...

>>15672301

>>15672439

>>15672414
In startups you hire the smart people first or you go bankrupt, and you might go bankrupt anyway. The US has a startup culture and Europe and Japan don't because US bankruptcy law doesn't treat a dead business as a moral failure. Shit happens, move on. Astra played a little too close to the software startup "move fast and break things" ethos but that willingness to take risks is vital.

Normies will not care until there are boots on the moon again, and even that will be a flash in the pan. Boots on Mars will probably be more significant for engagement, but the tragic answer is that normies do not care. Only autists and pioneers genuinely care, and it's always been this way.

>>15672579
Well, YOU can't

Why can't they just test the hot staging on the ground with an inert booster with the real dome

>>15672554
This is like asking how to make normies interested in trains. They are very important in the economical pipeline that affects their lives and some might even use them, but the normies are simply incapable of caring for too long.

>>15672584
Why must you step on that poor anon's dreams man

>>15672554
Money

It is interesting to note that those tech demonstrations and proposed stations have backers with money, but there is still no profit to be made here yet, no material that can only be made in zero G, nobody to buy stuff you make in orbit to save money on launch costs. Once commercial stations are in orbit though, you start opening up supply chains (tourism and consumables) that anybody can buy and sell to.

>>15672602
because it's not enough
You get 30% energy conversion at best with the solar panels and then lose at least another 50% (I can't find a precise number) of that with the LEDs. And that's asssuming a 1:1 area ratio of panels and LEDs, which is stupid because the whole appeal is to stack layers of them.
And then you have the night hours, so double the loss.
So you need 100x, probably 1000x the space in solar panels to power one vertical farm, at that point just farm normally

>>15672612(me)
to be clear I like vertical farming and the energy cost is worth it in some markets, especially if you can essentially make the transportation and labor cost 0, I'm just pointing out it's unfortunately not as simple as slapping solar panels on the roof of the building

Luna is great. It's has the highest planet-moon size ratio (not counting dwarf planets), only planetary moon in the inner solar system, and if I recall correctly it's the only moon other than Io to be mostly rocky (all others are icy). It's also the only moon other than Titan with landers so far and also a prime candidate for colonization.

>Microgravity is known to cause an atrophy of the bone marrow and the immune system leading to the so-called “space anemia” and a defect in the “T” lymphocytes. Experiments on Spacelab 1 found a surprising gravity dependence of the lymphocyte cells (a critical part of the human immune system responsible for the production of immunoglobulins and cell mediated immunity ) (Cogoli, 1984). Cultures of human lymphocytes exposed in microgravity to the mitogen Concanavalin A showed less than three percent of the activation of ground controls. The significance of this possible “space-immunosuppression” goes beyond the danger of a simple infection. In particular, T cells also help fight off growing neoplasms, and a suppression of this system may hamper the astronaut’s ability to fight off a cancer while in orbit — a serious hazard in the high radiation environment of space.

>On the opposite end of the spectrum from the large radius, slowly rotating, space habitat is a device I am investigating at MIT’s Man-Vehicle Laboratory called the Artificial Gravity Sleeper (AGS). The AGS system is a 2 meter radius centrifuge designed to rotate a subject about an axis through the head, providing a centripetal acceleration gradient (100% gradient) which is maximal in the feet and zero at the head. The AGS is being evaluated for its ability to provide physiologic conditioning to an astronaut during sleep, as well as for its ability to enhance exercise by providing a gravity gradient for an astronaut to work against. For a 1.66 meter tall person, the AGS is rotated at a speed of 23.2 rpm to provide a one gravity acceleration at the foot plate.
>The AGS system is designed for use on Space Station (figure 12) but would be equally of value on the Lunar or Martian surface. It is hypothesized that rotation during sleep will help reverse fluid shifts, maintain vascular tone, provide centripetal acceleration for T lymphocytes, and afford some stress to the skeletal system. The AGS would also be equipped with a “cycle ergometer” and a device for “simulating stair climbing” in order to further condition the muscular, cardiovascular, and skeletal systems.

>The 10 000 or so kilogrammes (22 000 pounds), Earth weight of course, Moon car consisted of a 5 metre (about 16.5 feet) diameter spherical compartment for the crew to which a single telescopic leg was attached, to which was attached an unpiloted yet powered caterpillar track element. The electricity needed to power this vehicle would be provided by the sun and some sort of hydrogen peroxide turbine. This electricity would power the large gyroscope needed to keep the Moon car driving along in a vertical position. Just imagine an 18 metre (60 feet) high pogo stick travelling at speeds of up to 150 kilometres/hour (close to 95 miles/hour) and you get the idea
>If the crew of the Moon car spotted an obstacle that could not be crossed, at low speed of course, a canyon or crevasse for example, the pilot would retract the telescopic leg inside the spherical compartment. After looking into an instrument which would give him the width of the obstacle and the distance separating it from the Moon car, he would push a button / lever / thingee, thus shoving a (controllable?) volume of compressed air inside the telescopic leg. Said leg would extend, sending the Moon car in the air. It sent the Moon car upward, up to 125 metres (400 feet) above the surface of our satellite. A chasm up to 100 metre (330 feet) wide could be vanquished.

Angara isn't likely to be used as the basis for a superheavy because neither pad 35/1 at Plesetsk or 1A at Vostochny are built to handle a vehicle with six boosters. Soyuz-5 isn't likely because it doesn't have a pad at all, let alone one that could handle a Zenit Heavy or superheavy design. A Russian superheavy moon rocket isn't likely under any circumstances.

how do you convince normalfags that space exploration is necessary

>>15673283
why would you need to?

>>15673226
Russia doesn't have enough money. They'll probably put two cosmonauts in a Soyuz, attach a Progress for additional fuel and use Angara to send the combo around the Moon like Apollo 8 just to keep from being totally upstaged by Artemis.

>>15673283
The resources gathered from asteroid mining would remove the need to extract them from the earth and factories on Mars could produce as much CO2 as they want without any danger to the environment given it’s already a radioactive wasteland which allows for industry to be moved away from the earth.

Obviously none of this will stand up to any real scrutiny and it’s so far in the future it may as well be fantasy, but the fact you have to argue with normies about justifying space exploration already shows they are fucking idiots so I wouldn’t worry too much.

>>15673428
Yes, but it's still funny.

One option is to roll the Space Launch System out to the launch pad in what Parsons called a "short stack" configuration without the Orion spacecraft on top, then load cryogenic propellants into the rocket for the wet dress rehearsal. In that scenario, the rocket would return to the assembly building for the Orion spacecraft to be attached, followed by another sequence of tests before rolling back to the pad for launch.

>>15673378
This is sfg not racism space command

Parsons said NASA is now studying ways to service the flight termination system while the SLS rocket is on the launch pad. Assuming everything else is ready, that could allow NASA to shift from a dress rehearsal directly into a real launch attempt without returning the rocket to the assembly building.

I hope Stoke succeeds.

Asteroid mining has the potential of turning a scarce resource into a common resource. Put refineries in an orbit that doesn't require much energy to maintain it's orbit, only send ultra-pure refined products down to Earth.

>>15672900

It might make sense to do crude refining in space and use crude re-entry vehicles to get large quantities of heavy material down to Earth where it's easy to work with.

>>15673127
Indeed.
The ISS has been a non stop human presence in space for over 20 years now, and along with the Mars rover program it is pretty much the rebirth of space exploration since the downfall after Apollo 17. Yeah, Starship will be the thing that finally unlocks all the potential but it didn't start there.
And of course those aren't perfect and I have my own issues, but the ISS is quite an amazing feat and I feel bad for not following it too much.

If there was another shuttle loss of crew between Challenger and roughly the comittment to the ISS (so like 94-96), resulting in the cancellation of the shuttle after a shorter number of flights than irl post-Columbia (because there is no ISS to complete), what do you think would happen in NASA?
>Total abandonments of American creed spaceflight
>Abandonment of independent American crewed spaceflight, NASA relies on Soyuz for the foreseeable future with limited contribution to MIR and Mir 2/1.5

>>15674134
How does the loss of crew happen? Is it Columbia but sooner? Another SRB failure? In space and unrelated to takeoff/landing?

>>15674152
Let’s say Columbia as a baseline
I imagine an ascent LOC would be the worse case for NASA

>>15674152

>>15674134
>NASA Makes a mini-shuttle (think HL20/42)
Probably this and turning the STS into an unmanned heavy lifter i.e. Shuttle-C. Basically circling back to how things should have been done from post-Apollo: Crew in a small lifting body going to a station you build with 4 or 5 heavy lift boosters

>>15674134
I think the push would have been for Shuttle II, but exactly what shape that took would have depended on the exact date and what the economic conditions were in the US at the time. It's also important to remember that the USSR was still up and kicking for about half of that time period and we wouldn't have wanted to loose the greatest portion of our space launch capability at a time when Buran and the Evil Empire are still looming over our policy decisions.

I'd say that if the event is in the 80s you'd be more likely to see a fullsized 2nd gen shuttle, while if its in the 90s you're more likely to see a mini-shuttle designed to take advantage of the EELV rockets that just got commissioned. Either way it's going to fuck up station construction plans immensely. There's a non-zero chance that all of the major spaceflight players just decide to pursue their own Hermes+Columbus plans independent of each other.

>>15674178
>>15674170

Yes I agree the economic conditions would be important, the early 90s crisis, the gulf war, the peace dividends were probably not very conductive to a large space project... but at the same time, if it happens a bit before the 1992 election, an ambitious development program of the shuttle could be approved by Bush sr to help his reelection odds in key states (CA, TX, FL...) in said time of aerospace sector crisis.

American military downsizing was happening as early as 1988, the USAF answer to Energia (ASL, Barbarian) was not particularly urgent, I think NASA would look more at cooperation than competition with USSR in 1989+

If the failure happens after the NASA access to space study, I imagine that the Mini-shuttle would be more favoured.
A problem is that NASA lacked a heavy launcher at the time, EELV was still some years in the future, and projects like NLS were still only in the concept phase. Shuttle C was overkill for crewed spacecraft, and Titan IV was both expensive and USAF's dedicated launcher.
I wonder if a mini-shuttle could have been designed as launcher agnostic, with options as backup notably on Ariane 5, potentially Energia M or proton (lol) .

>their own Hermes+Columbus plans independent of each other.
That'd be sad, although I don't think NASA stopping or downgrading the shuttle would save Hermes itself, this progrma was too much of a mess, it may be more sensibly downgraded however.

>>15674180
It probably would be quicker than the IRL retirement, without the need to complete ISS, If it happens in the 80s there's still several years of DOD and the odd Comsat launch/repair, if it happens shortly after 93 I guess Shuttle-MIR program would be completed, between the two... I think the retirement could be very quick.

Shuttle-derived may be less popular, but NASA still had that obsession with LH2 boosters (see all the STME proposals at the time), and of course, there was the need to keep the centers and thiokol busy...

"Interstage extension for hot gas venting added to enable Starship to turn on its engines while booster engines still firing!"

Probably wouldn't be much to see, but it'd lift a massive amount of dust all over the thin atmosphere that would take countless years to dissipate

>>15674321
Just detonate another nuke above the dust

>>15674321
>that would take countless years to dissipate
Why would that happen? The dust falls to the ground unless blown up by wind

my concern is on long term reusability, but perhaps they plan to swap the interstage out as it wears down?
