If a person on ISS or any other LEO space station needed to orient themselves to a fixed point on Earth for ten minutes, what would be the best way to determine how to orientate themselves and keep themselves orientated to that point for a period of about ten minutes? Keep in mind that the station is moving rapidly so they will need to constantly make minor changes to their orientation to maintain orientation towards the fixed point.

Materials science and electronics in that show are way ahead of where they were in our time, and they barely acknowledge it

This is apparently because one of the show's premises is NASA's funding percentage of GDP never went down, and then it proceeded to double that percentage by "becoming self-sufficient" via patent licensing. One of the other premises is that women joined the workforce in greater numbers due to the ERA being ratified.

I'm skeptical that even with a hundred billion dollars a year starting in the 70s, and apparently twice the geniuses, you could get Sea Dragon, fusion, a moon base the size of a small town, miniaturized NERVA and two separate space shuttle designs built in 20 years followed up by a manned Mars mission

Sea Dragon wouldn't work and nuclear shuttle a meme.
Instead, Giant Nose-To-Ass Staged shuttle makes fully reusable launch with 250 tonnes of payload per flight a real thing.
Big nose to ass shuttle enables a fully reusable Moon landing system with up to 20 tonnes of surface payload and a crew of 5 astronauts. This system is used to build up the Moon base.
The launch vehicle also enables the big space stations, and later on it plus foreign copycat launchers allow for the Mars vehicles to be assembled in orbit.
I haven't watched the show but if you want to get a Moon base, big ring station in Earth orbit, and humans running around on Mars by the year 2000, that's what you'd need (barring magic technology that doesn't real)

I think they went a bit too far with some of the rockets and designs but the plan outlined in the show is semi-reasonable.
IRL NASA planned to upgrade the Saturn V with some boosters, while also flying the Space Shuttle - but a different design that was more reusable and didn’t use solids.
From here, they’d use nuclear tugs to leave LEO and place dedicated landers into lunar orbit, or even mars. The show fumbles all of it but whatever.
If they added boosters to the Saturn V, used the shuttle (suspension of disbelief) but only for LEO, added nuclear tugs, and no Sea Dragon, it wouldn’t be that far from what NASA planned.
Another issue is that the show glosses over the Soviet space program other than DUDE THE SOVIETS HAVE BURAN!!!!!!

the thing with shuttle is that for all its problems it could have still been cost-effective if nasa had the budget to fly it 50 times a year. if you have a bigass space base in LEO, a station in GEO, a station in lunar orbit, and a moon base, that's 3 stations that will need maybe 4 crew rotations a year and we'll say 12 crew rotations a year for the base. that's 24 shuttle flights alone. DOD was averaging around 7 titan 3 launches a year and if you move those all to shuttle that gets you to 31. then maybe another 10 a year for commercial payloads and interplanetary probes. i'm still not sure you can get to 50 in a SENPAI-esque universe but you can get close.
soviets would've definitely gotten their own nuclear tugs once nasa had theirs running.

No don't worry, if you read ahead I'm saying big ass two stage reusable rocket (happens to be flyback stages instead of propulsive landing because 70's) is used to put up to 250 tonnes of payload into LEO, and one of those 250 tonne payloads is a reusable LEO to Moon's surface to LEO vehicle.

I know. Back when Boeing was still based.
Funny enough the “upper stage/upper plane” has 6 km/s of delta V even with 400+ tons of payload. A lunar transfer is 3.2 km/s, orbit insertion is 0.9 km/s, and landing is 1.7 km/s. TLDR; a fully fueled upper stage in LEO could land 400+ tons on the moon, despite being a fuckhuge spaceplane.

This fuckin thing. Enormous, methalox stage 1 hydrolox stage 2, kinda combines the concept of Sea Dragon (built it bigger, stupid) and Starship without the miniaturized computers (wings and cockpits instead of magic electric pixies). Since it's TSTO it should actually have been feasible to build, too. If structural mass esitmates were too optimistic, stretch the vehicle and add engines as needed, until the resulting payload mass is equal to the target value. Define launch vehicle payload mass by what sized vehicle is necessary to get a crew to the Moon and back to Earth orbit in a single stage with a significant payload, and go from there.

Sue but that's our timeline. In the show's timeline Shuttle could have been a smaller version of the Freighter, rather than our orange tank POS. The in-line two stage crew Shuttle would be a replacement for the Saturn 1B, and Saturn V could have kept launching until the Freighter design was completed and operational. In that case, In-Line Shuttle by 1976, Freighter by 1985, acceleration of space frontier subsequent to Freighter's low low cost per kilogram translating to sudden leap in progress.

[Anonymous No.14721045]

>>14721030
Nowadays? Nah, not in my opinion. Modern computers and TVC systems are too good. Go back to 1970's tech and horizontal flyback boosters would have been worth developing, for sure. That is to say, they would have had a functioning flyback booster in less time for fewer dollars than a propulsive landing booster, and the overall performance losses compared to a hypothetical vertical propulsive landing booster would have been a wash anyway. I would think though that after a couple decades of computer improvements they could replace the winged first stage with a simpler, cylindrical booster that would land on fold-out legs near the launch pad for restacking.

Dude I was trying to clarify what you were talking about in terms of when methalox works better. I ask because it's been stated before that methane in a nuclear thermal rocket would get like 610 Isp, and when you shake down the mass fractions and engine thrust due to methane being much denser than hydrogen, methane can offer higher stage delta V for many situations. I need to know if you meant to say methalox or methane, basically. That would answer my question.

[Anonymous No.14721065]

>>14721003
yeah that'd be a really sensible progression, especially since the original idea with shuttle was that it was going to be retired by 1990.

New Mars mission radiation dose paper just dropped
https://arxiv.org/abs/2208.00892

It's pretty thorough, it even covers the unknowns like phosphenes (I wrote a paper about these once).

Lots of interesting analysis but the key takeaway I think is that regardless of shielding strategies, any Mars astronaut will take more than the lifetime limit of 1 Sv and effectively end their careers before they start

They may have to recruit young astronauts specifically for a Mars mission and only one Mars mission

The study it's self is pretty interesting, but it would have been much better if they tested a range of other shielding regimes.
Aluminium isogrid is pretty much the bare minimum for shielding.
30cm of water, 30cm dirt, 100m of air all would have been fairly interesting.

>>14721298
Even with the 4 month transfer there can be better shielding than 5g cm aluminium.
Putting sleeping quarters in the core of the ship and surrounding it with dense cargo could reduce exposure much more than that, even to highly energetic particles.

Would a mars cycler make sense if you could grow the food for the journey on the cycler? A flying greenhouse?
Humans will consume about 3 times their weight in food during a mars transit, some of that is water weight that can be recycled, but if you're intending to transport say 50,000 humans over the next 50 years, that's around 10,000 tons of dead weight that need to be put onto a mars transfer.

This is not to mention the other potential advantages, IE rad shielding, leg room ect.
Obviously it only makes sense for human cargo.

I'm not entirely sure about that.
The switch to hard line communism/nationalism in particular is worrying - ideal for war, much less ideal for economy growth
The foreign investors are moving elsewhere - Vietnam, Philippines, Indonesia. Chinese are not as cheap as they used and often act straight up hostile.
EU and US are looking for alternative suppliers, be it foreign or domestic for pretty much everything already.
CCP is cracking down on Chinese businessmen (like Imagine if Elon disappeared after he criticised Biden - that's what's going on in China)
And perhaps most importantly their reality market and banking system are showing lots of massive cracks (much like the buildings) which CCP is having harder and harder time plugging up

I admit, people have been doomposting about China for at least a decade now and nothing happened, but the things were never this bad.
I wish I'm wrong.

To be as fair to Astra as possible, the plan they have outlined isn't a bad one. A dirt cheap mass produced rocket should be able to carve out a market niche, and if you're launching payloads to build out constellations your customers will be tolerant of a higher failure rate. It's just that their "super high volume mass production" doesn't seem to measure up to what's being done right now by Rocket Lab, and you'll never be able to attract any volume of customers if your 90% success rate turns out to be 40% when put into practice.

[Anonymous No.14724260]

>>14724253
Another issue is:
1) Their rocket is too small. It can’t even lift the 55 kilo Blacksky sats Electron does. They have no market.
2) 90% success rate doesn’t apply to “regular” customers like NASA, who don’t have megaconstellations.

I think the market issue is just a symptom of how small the commercial launch market is. Especially with regards to small satellites. RocketLab wanted 1 electron launch ever 3 days, no reusability, and didn’t plan on making any other bigger rocket. They’ve gone back on all those promises because Electron doesn’t even fly monthly.
SpaceX, even, is going all-in on Starlink to fund Starship, despite originally planning on using the commercial launch market to fund it back in 2017. But it seems like they realized there isn’t enough money in that.

The problem for China is that it's supply lines to middle Eastern oil and gas are far outside the reach of it's missile forces, and the PLAN is far from being able to compete with the USN in the open ocean.
The other problem is that they cannot sink Japan.

If a war broke out it with the US (beyond just Taiwan), it would likely involve an Island hopping campaign in South East Asia as China would seek to extend the coverage of their missile forces and their ASW aircraft (submarines cannot be targeted by missiles, and the US has a much better submarine force than China).
It would also be a battle to keep Japan under supply and protect their convoys from Chinese submarines.

The Korean peninsula is a big question mark, because South Korea is much more vulnerable than Japan to blockade and they also have North Korea to worry about.
They have been more neutral in regards to China historically as a result.

when Elon says 1 year it that means at least 2. I personally am hopeful of seeing a booster fly this year

successful flight. he said he expects the first launch to be next month.

I wonder how China plans to force project desu. That’s a lot of ocean and there are only so many ships.
I’m worried about nukes though. I would probably die instantly because I live in a big US city

they should just pack a 5m monolothic telescope with better instruments in Starship

If China goes to war with Taiwan, America, and Japan they're going to war with a hell of a lot more than just that.

I really don't see how a war could happen between two major nuclear powers without it going nuclear.

when will they release information about the Trappist observations they made

What did he mean by "successful"? Also 12 month? Wtf? We will never haver orbital...

Those are asterisks, so it's for emphasis. He's basically saying he thinks they'll make orbit within a year of starting the orbital launch campaign.

>they'll make orbit within a year
Like full-fledged orbit without burning up in the atmosphere and splashing down in the ocean?

He means an orbital launch undergoing what will be considered standard procedures. Remember that they changed the plan and are going to be trying to catch at least the booster with the tower on the very first flight. With how long they've been waiting they're no longer at the point of just trying to get a system that successfully reaches orbit. They're ready to start trying to fly real working articles, hence why they're going to be deploying Starlink satellites with it. Depending on how difficult the catching and TPS prove to be it could be a while of them flying expendable Starships until they learn how to reuse them.

The data is public from the first tranche, but it's not something you can just eyeball. I suspect it will be a few months before there is a paper. Especially because only part of the program has been done so far, and publishing half of it is a bit of a waste of time.

Someone will be working on the data, probably multiple people. And it's an entirely new instrument with artifacts which were not predicted on the ground. It takes time to understand the systematics.
