Anyway, I still want an SSTO. Let's make an air-breathing engine that can turn into a rocket engine outside the atmosphere and stick it on a space plane that can tip itself straight up for vertical launches on planets with no air.
Who's with me?

Doing some back of the napkin math that seems like about .15kg of ice per square meter giver or take. Doesn’t seem that unreasonable. It’s pretty thin.

>he has been saying the exact same thing for almost ten years now, maybe more.
What causes such behavior?

>>16178876
hear me out, how about we give it a drop tank. That way it will be way lighter and smaller for the same payload to orbit. We probably need boosters to lift it fully fuelled, just enough to lob it out the thick part of the atmopshere and let it do it's ssto thing. to minimize on cost they should pprobably be something simple like solid rocket boosters.

>>16178881
it works

>>16178876
Read up a little bit about the difficulties air breathing engines experience due to issues like inlet shockwaves, you seething transphobic chud. If you had two IQ points to rub together maybe you wouldn't be such an ignorant know-nothing pseud.

I could live with that.

I want to hear the geostationary satellites operators cope for this. Last time I heard they were mumbling something about ground stations.

>>16178888
>Read up a little bit about the difficulties air breathing engines experience due to issues like inlet shockwaves
So you're saying we might have to solve problems to make technology better?
Wow, who knew technology would require problem-solving?

>>16178893
its not going well, you have already had a bunch of mergers and acquisitions I think

>>16178876
As cool as a SSTO would be, it offers really no benefit over a multi stage design where all stages are reuseable.

>>16178876
You need either a revolution in engine technology, extremely expensive materials or accepting you'll only be getting a miniscule payload to orbit. Actually you probably need all three at once.

>>16178900

>>16178901
>As cool as a SSTO would be, it offers really no benefit over a multi stage design where all stages are reuseable.
Yeah, but it's fucking COOL!
And don't tell me that's not a valid consideration. A priority, no, but valid nonetheless.

>>16178903
As much as I hate Starlink-style constellations (and I do because competitors are going to fill every square inch of the sky with satellites until you can't see the fucking stars anymore), it does have one massive advantage over geostationary systems: It's decentralized. A lost satellite or two makes very little difference to its functionality.

Yeah, my uncle works at nasa and he said the space shuttle 2 is going to be made out of wood.

>>16178939
I don't know if anybody has tried to put wood in a vacuum but I don't think it would tolerate either the UV exposure or vacuum very well

The audio for the twitter video didn't have any bangs or pops at the end of the burn, so it might have been okay. Maybe

>>16179008
Is it like a veneer sheet they epoxy onto a normal cubesat, or is the satellite itself built on a skeleton of wood? It seems like the kind of thing that'd have just a thin layer of paneling like an Atari or old station wagon.

>For more than five weeks, Dream Chaser and Shooting Star were subjected to multiple cold-hot cycles in a vacuum environment, between -150F to +250F, with teams conducting functional tests at temperature plateaus to verify system performance.
>Temperatures in space can range from the extremely cold – hundreds of degrees below freezing – to several hundred degrees Fahrenheit due to radiation from the sun. TVAC testing is a realistic thermal simulation of the flight environment and critical to ensuring mission success.

This might explain why things are taking so long

>>16179034
I remember reading about this in magazines when I was in school. Feels like it's been in development forever.

Would you take the one way trip on a generation ship? It seems like the most plausible form of large scale travel, but you are guaranteed to never see it end due to the length of the trip.

>>16178880
>>16179049
>someone replied
I guess it would depend on some situational factors like a function of temp and humidity on launch day by the time it sits fueled plus some other factors like evap/transpiration from sunlight. Quite a bit of ice can buildup on uninsulated cryo vessles

>>16179041
Sure. I'm not actually a viable option for a generation ship that depends on you know making multiple generations but I wouldn't mind ending up in a cult worshipping the ship with its maintenance manuals acting as holy texts.

>>16178921
I figure some of the starlink adopters are people who were previously priced out of other sat internet services, so it's not exactly a 0 sum thing

>the test needed to be completed this week, as after Sunday, SaxaVord will need to be shut down until the end of June because of bird breeding in the area
Also this guy says he has a source in the company confirming it was successful

>>16178867
is this what starbase factory is supposed to look like?

>>16178890
I'm living on board at the moment and thinking about starlink, it is a bit power hungry though. Biggest thing stopping me is that coastal areas are kind of a grey zone. Most people report no issues on the roaming package soclong as you arent way offshore but they can rugpull you any time since it's not meant to be used on the water and then you are stuck with either buying the retard expensive marine package or having to flip a dish that's now a paper weight. Wish they would offer a package for cruisers but i guess its a small market and they are jews.

>>16179089
no competition means they can charge what they want, unfortunately.

>>16179091
I know I know. I wouldn't mind paying the same price or a bit more as boomers do for their caravan roaming package since its basically the same service, not far enough away from ground stations for needing laser comms. It's just being stuck in a grey area that is garbage.

>>16178927
looks very Myst

>>16179068
>SaxaVord will need to be shut down until the end of June because of bird breeding
it's almost as bad as JAXA having to shut down Tanagashima because the fishing lobby saying that their catch was getting scared

>>16179078
that's the starlink factory

All you chemical rocket cultists need to watch Dr. O'Dowd's newest video. He really spells out how difficult it is to get humans to our nearest star. The distances, times, and ship size all help explain why it can not and will not ever be possible with chemical rockets. He clearly points to the water shield being key to space exploration. You can't launch the water let alone the ship, crew, and misc junk. It would take Starship hundreds if not thousands of launches to build a single interstellar generation ship that had any hopes of success. That's a single ship too! Even if you scale that down for Mars it's only going to be 1/4 the scale at best. Becoming a multi planet species is impossible with ONLY CHEMICAL ROCKETS. Hopefully as Tesla collapses into ass gas you cultists will begin to wake up and do some real work towards space flight in the 21st Century.

i hate that we're so reliant on spacex because space is too difficult for everyone else

What are your thoughts on living on Mars and having your cat stick to the ceiling with his claws and you cant get him down.

>>16179227
cats go out the airlock

>>16179230
(You) first

>>16179213
it was 15 refills to get to mars
and while it takes a similar dV to get to the moon, the required payload for HLS landing 1 is going to be peanuts because no useful mass can be brought back on orion. so I would still expect low teens at most

>>16179122
It would make much more sense to send off our DNA and have humans lab-grown on site, instead of making flying city to send out. Hell cryo sleep is a much more feasible challenge then keeping 500 people alive for 500 years.

>>16179238
Fuck off

>>16179234
I wonder how fast all that cryo would boil off
It should be possible to get a good estimate, we know the material starship tanks are made out of

If a full orbital tank takes 2 years to boil, we could have fuel sitting in orbit just to be ready for anything, and you just top off the fuel depo whenever you have the chance
If it's 2 months to boil, then you need to tightly coordinate all 15+ launches

Why can't spacex use magnets to hold the tiles on?

The obvious problem with putting magnets in the tiles is magnets degrade wtih heat, and its unclear what would keep them from sliding around

But what if you put magnets on the inside of the hull, with very magnetic steel inside the tiles. Magnets get better when chilled, and each tile is attracted to a specifc point

you need to follow enough spaceflight related accounts, mute accounts you don't want to see and generally curate your feed

>>16179636
>>16179630
by curate you can click on the upper right corner of a post on the main feed and click "Not interested in this post"

also, interacting with posts is a sign for the algorithm to feed you more of the same
if you see something you don't like, don't start replying to it if you don't want to see more of the same
just mute the account or do the "not interested" thing, you also need to stop following accounts if they start posting too much uninteresting shit (which has happened with some bigger accounts after monetization)

>The calendar maintains a seven-sol week, but the week is restarted from its first sol at the start of each month. If a month has 27 sols, this causes the final sol of the week to be omitted.
>This is partly for tidiness and can also be rationalised as making the average length of the Martian week close to the average length of the Terrestrial week; 28 Earth days is very close to 27+1⁄4 Martian sols, whereas a month is an average length of 27+5⁄6 Martian sols.

>>16179838
there are 2 issues
1. a planet in a red dwarf HZ will be tidally locked and therefore a slow rotation and therefore a weak magnetic field
2. a planet in a red dwarf HZ is vastly closer to its star than Earth and therefore will be hit by much more intense CMEs, much more frequently. even a planet with a decent field would struggle at that distance

Cats aren't afraid of heights.
When it's tired it will just leave the ceiling and drop down, probably on its legs.
I wonder which animal would adapt better at low gravity, I think cats have good chances.
Fish most probably, but being in water is a special case.
It probably makes also some difference if they are born there.

It's even worse: at Mars' aphelion, the southern hemispere is in its winter, so the southern hemisphere has harsher seasons in general. The winters in the south are brutal, even for mars, and while the summers are very hot, they're also very short. Even worse again, the end of southern summer is dust storm season, which lowers temps by quite a bit and sometimes spreads to the north.
The south is shit.
>>16179179
Northern spring/southern fall is actually the longest season (it lasts 194 sols). Northern fall (shortest season) is about 52 sols shorter.
>>16179695
the better way is to do away with months (months are lunar, no utility on mars) and use intervals of solar longitude (Ls), which is relatively easy to locally calculate even if you've lost track of time. Rover operators use this, so it seems pretty useful.

>>16180030
meant to post picrel instead, but whatever.
Might as well post about how shit dust storms are: Did you know that every time mars has a significant dust storm, large amounts of water are transported to the upper atmosphere and lost to space? Yeah.

Hey fuckwit answer >>16180034

It's an absolutely trivial answer if you understand the principles behind spin gravity. lrn2physics

>>16180047
How do you intend to dock that shit?

>>16180034
>>16180047
I prefer martian calendar discussions.

>>16180049
Slow down the station rotation for docks, but what if you just rotate the ships individually in place for artificial gravity??

>>16180034
Since the astronauts will be at a small radius they will experience a smaller G than the rest of the ship
If you want the astronauts at 10m radius to have 0.5 G, the bottom of the ship at 50m will be at 2.5 G
So it depends if starship is structurally strong enough to not rip apart when you hang it by its tip and at super gravity
Since it isn't optimized to do this, it saves weight by not being able to do this
So it shouldn't work.

>>16180052
Coriolis force would make that contraption a roman shower no matter which way you spin it.

I shall now remind /sfg/ that we have already seen a spinhab in action.
Thank you Nauka.

>>16180060
soyuz tried to deorbit the station

>>16180053
You could probably make spin gravity work on starship.
Take 2 of them, attach long (200m+) cables to their moint points, pull the cable taight, aim the starships towards eachother, then spin the whole thing along an axis perpendicular to the cables
This way, the top an bottom are 100m radius and 150m radius, so they have similar-ish G's.

some competition for starlink direct to-cell, ASTS satellites are arguably much more effective and will be able to do some data as well, but they only have one prototype satellite in space as far as I know and its not going to be a megaconstellation
you also have starlink v2 might remove most of that competitive advantage of ASTS

I'm so excited. You literally can't knock blue. They do some serious shit and do what they say they are going to do. Theyve been flying astronuats since years before SpaceX. I think it's an acheivement which doesn't get enough coverage in certain quaters.

>>16180324
They built the first reusable rocket

>>16180326
Nobody even seems to know or care this fact. SpaceX even had to violate the Blue patent on droneship recovery because Blue has been cooking serious business for a long time.

Allegedly the crew of Columbia died within seconds of the spacecraft depressurization due to "muh exposure to space". But werent they wearing pressure suits?

>>16180340
Obviously not if they died within seconds moron

>>16180343
So they decided to undress for that particular reentry?

>>16180340
The pressure suits do not have internal air supplies or the ability to maintain internal pressure, and depend on spacecraft systems for it. The only purpose of the suit is to prevent death in the event of a Soyuz 11 style loss of cabin pressure.

>>16180340
procedure was to take them off during reentry for comfort

>>16180340
they had the visors up

>>16180340
>The remains of the crew members indicated they all experienced depressurization. The astronauts' helmets have a visor that, when closed, can temporarily protect the crew member from depressurization. Some of the crew members had not closed their visors, and one was not wearing a helmet; this would indicate that depressurization occurred quickly before they could take protective measures.

>>16180351
We should have reentered two crews at the same time, so that if one crew is lost, at least we have another redundant crew

>>16180351
>The pressure suits do not have internal air supplies
Wouldnt kill you in seconds
>or the ability to maintain internal pressure
what do you mean?
Then they must not be pressure suits.

Musk's plan is to build one or two a day, which is about the same as Tesla's output by raw material mass, and comparable to Boeing's plane output. Those all being reusable, 1000 launches might take place Q1 2030. You old space guys don't understand what a paradigm shift this rocket is

i think they probably got burned pretty bad

>>16180355

>>16180357
I mean the suits are not self-pressurizing: an external air supply provides pressure, along with breathable air.

>>16180357
>basically what happened to Columbia which allegedly killed the crew

I’m tired of pretending it’s funny; It is an insult to every tax paying American that Starliner got the bigger $$$ contract and has yet to deliver a SINGLE soul to orbit. Dragon 2 got the “budget deal,” and is arguably in its latter-half life cycle having already safely delivered+returned lots of people to space.
