not on mars that's for sure.

are there any info with regards to the research spacex is doing with the life support cargo they are bringing to mars in 2022? is 2022 still possible?

>>11921243
yeah honestly i'd rather be in mars than on it

>>11921239
The future of spaceflight should be earth science to research and save the world from global warming and sea level rise, we're wasting money going to the moon and mars when we have so many problems here that need to be fixed, like starvation, racism, and global warming

>>11921249
based!

>>11921244
SpaceX already knows how to deal with life support for CrewDragon. They've done extensive testing already. This will carry over to Starship. But long term goal is vacuum sealed habitats on Mars, augmented by underground tunnels.

I think a good place could be Hellas Planitia, the big crater on the bottom right, since it has much denser atmosphere, and where drilling for water could be possible

There is money to be made from solving these problems. Money that could contribute to a martian colony.

How we will go aboit building it depends on the budget and it is looking like the budget will be low.

I would settle for a home among the lava tubes. Personally I would prefer a location closer to the equator so I can simply use CSP for energy. Because the lifespan of solar panels is too low and nuclear is dangerous and expensive.

Light can also be condensed (probably does not need to be) and reflected down into the tunnels for crop growth.

The biggest problem is water, but there is mounting evidence that water ice is contained below the surface of large areas near the equator. It might be more difficult to extract than the polar caps but trips to the pole and back to collect ice would be long, dangerous and expensive.

Hypothetically, how would you conduct a rescue of people stranded on the surface of Mars?

>At the time of its arrival at the KSC, Columbia still had 6,000 of its 30,000 tiles remaining to be installed. However, many of the tiles that had been originally installed had to be replaced, requiring two years of installation before Columbia could fly.

>>11922404
Just send the next mission in the series unmanned and pick up the stranded crew. Otherwise there is no saving them.

>>11922419
Based, truly an American aerospace industry achievement

>>11922404
Didn't NASA recently propose a trajectory to Mars that includes a Venus flyby? I think it means you can send things outside of the 2 year synod period. Even a small amount of supplies should be enough to see them through until the rescue ship

Space Shuttle was such a colossal mistake, it's ironic that something that looked so futuristic for its time actually embodied all the bad parts and inefficiencies of the Old Space.

>>11922419
The more I read about the shuttle program, the more I question what the FUCK they were thinking

>>11922434
>NASA secured funding from the US Air Force's budget in exchange for USAF input to the design process. In order to fulfill the USAF's mission to launch payloads into polar orbit, the USAF insisted on a very large cross-range requirement. This necessitated the Shuttle's huge delta wings, which are far larger than the stub wings of the original design. Besides adding drag and weight (almost 20 percent),the excessive number of heat tiles needed to protect the delta wings added greatly to maintenance costs, besides increasing operational risks such as resulted in the Columbia disaster.

this is hilarious

>At Vandenberg Air Force Base the USAF duplicated the entire infrastructure needed to launch and service the Space Shuttle, at a cost of over 4 billion dollars. Following the Challenger explosion, the facility was dismantled after never having launched a single Shuttle mission.

>NASA administrator Michael D. Griffin argued in a 2007 paper that the Saturn program, if continued, could have provided six manned launches per year – two of them to the Moon – at the same cost as the Shuttle program, with an additional ability to loft infrastructure for further missions:
>"If we had done all this, we would be on Mars today, not writing about it as a subject for "the next 50 years." We would have decades of experience operating long-duration space systems in Earth orbit, and similar decades of experience in exploring and learning to utilize the Moon."

CF4 is mega greenhouse gas because its absorption band doesn't overlap with CO2 or water and those 2 are basically completely saturated on Earth.
Increasing amount of CO2 or water vapor in Earth's atmosphere is like taking a very dark brown surface that absorbs most of visible light and painting it a shade darker. It doesn't do much.
Increasing amount of CF4 on Earth is like painting silver thermal reflecting surface with black paint.
Mars atmosphere in that analogy is all silvery-white-transparent and it doesn't matter what exactly you add - a ton of CF4 would have about the same effect as a ton of CO2

The tech won't be that hard to develop, it'll involve modifying existing electric earth-moving equipment to work in vacuum and installing a thermal management system (such as a circulating water loop with a heater in the reservoir and a radiator, to handle high and low temp environments).
Later we can think about custom equipment to do things that we don't need to do on Earth, and modifying the Moon equipment designs to be less overbuilt than necessary, but we need to avoid falling into the trap of starting off trying to design hyper-specialized equipment at extreme cost and low production volumes with low success. We can't have Moon/Mars heavy equipment being as expensive and slow to build as Mars rovers.

>>11922747
This. Rockets aren't like boats, they (at least stuff that isn't the space shuttle) don't need to be super maintained, so it makes little sense to refer to them as female.

>>11922705
Not for making any further progress in space, no. Gravity is too strong to allow easy reusable SSTO, unlike on Mars, and of course there's the added cost and complexity that comes with everything needing to deal with being staged on a floating support structure, since the deeper layers of the atmosphere are no-go.

>>11922404
Redundancy, just park a second lander/transfer vehicle in orbit and if your first lander fails or whatever you send the backup down to get them.
Your main IP craft is low on fuel, have a lifeboat handy. Takes more time but ensures survival of crew.

>>11922738
Why even bother with sintering a huge landing pad when you could just screen a bunch of regolith for fist sized gravel and pack that down in a big circle?

>>11922755
>don't need to be super maintained
That has nothing to do with.
They're female in Anglo traditions because it's meant to invoke a mother goddess protecting those that inhabit her hull.

Its runaway greenhouse would be scientifically useful to climate/planetary science on earth.
Plus, I wanna know why it orbits backwards.
It's our twin-planet, so if any body could've supported life it would have been Venus whatever fucked its orbit and caused the greenhouse runaway may have killed life.

>>11922769
We're talking about realistic missions here. The solution is to just Send More Starships

>>11922773
Same reason asphalt is used to pave roads, you need something from compromising the structure
A couple layers of sintering prevents the rocket from frying the compacted pad and keeps dust from flying everywhere

>>11922675
question. how uneven can the terrain it lands on be? and is there any risk of starships engines 'digging' a hole under it as it tries to land making the landing dangerous / impossible? no idea what moon surface is like. I know there is like a layer of powder, but is it basically rock underneath that?

>>11922483
I think realistically most of the structure should be buried and surrounded by a second shell holding the building's water jacket, but the 1/3rd scale test demonstrated that at least basalt/polymer habs are structurally sound. They need to work on different print head shapes (so that different parts of the building can be laid down at different ideal speeds) and better thermal control, but those are manageable issues to solve.
The whole idea of creating all the printing material ISRU is retarded though, it would probably take decades just to bootstrap enough production to shit out a couple habs a year, if flights of tens, dozens, or even hundreds of Starships will be arriving in LMO then it is much more effective to send along spare tanks of material, and swap them out. Once emptied they could probably be cleaned out and used for some other kind of storage as well.

>>11922779
Same thing with fewer steps, sure.
I still can't get a Starship proxy to work though, probably need a mod or something.

>>11922775
>Plus, I wanna know why it orbits backwards.
It doesn't orbit backwards, what are you talking about. Venus orbits in the same direction around the Sun as any other planet.
Venus ROTATES retrograde, which is to say the sun on Venus rises in the west and sets in the east, also since Venus rotates so slowly its day is thousands of hours long.
Also, we know why Venus became a runaway greenhouse; it's too close to the Sun. That's it. Venus receives more than twice as much energy from the Sun than the Earth.

>>11922747
>>11922749
>>11922753
Not all ships are female, the Bismarck is male for example.

>>11922793
Krauts were fucking autistic though, there's no reason to follow their vehicle naming conventions. If they can ever save up enough money that doesn't go towards paying the rest of Europe welfare and launch their own rocket they can refer to it as male if they want.

>>11922781
Did you read my comment? I said the gravel is sifted, ie there is no significant amount of dust. I arbitrarily picked fist-sized rocks but really the goal would be to use a grain size that won't get blown around by the rocket plume, which in vacuum is not that large (because rocket plumes in vacuum get very diffuse very quickly).

>>11922793
That's the German tradition.

>>11922790
>Venus ROTATES retrograde
You're right. I messed up.
>we know why Venus became a runaway greenhouse; it's too close to the Sun.
You're wrong here, though.
Being close to the sun does not explain its dense atmosphere.

>>11922805

>>11921249
Yes, we have problems on earth, but focusing only on them and not evolving in different aspects is a waste of time and will probably end us up in stagnation. Our resources on earth are limited and some of them are very useful, but extremely hard to find. Taking humanity interplanetary not only preserves our species, but allows us to have much, much more resources which can be helpful in resolving problems that we have on earth.

>>11922788
Are you talking about Ksp? Pretty sure the other dude was asking about real-world missions.
As for a Starship proxy, just use the tools you already have, and use a stubby fixed-wing vehicle with a few big reaction wheels, and some RCS. All you need to do is set your autopilot to point radial-out during reentry and switch to point retrograde once you're subsonic, then land it like a rocket. It's actually pretty practical with nothing but stock Ksp.

>>11922807
Why do you think that "German Engineering" is synonymous with "Needlessly Complicated"?

>>11922796
I did and it’s not gonna work
Exhaust gas is gonna get between the rocks and blast dust everywhere, plus with the low lunar gravity, you risk launching large rocks everywhere
Gravel beds aren’t gonna work
Sparing a rover to build a compacted regolith landing pad and do a few sintering runs is easier than doing what you propose and safer as well

Massive solar sail to block light at the L1 point and solve global warming when?

>>11922800
>Being close to the sun does not explain its dense atmosphere.
Wrong.
Venus probably started off Earthlike with an Earthlike atmosphere, except with more nitrogen (Venus today has ~2x the nitrogen partial pressure as Earth, and would have had almost exactly the same when it formed). Basically it would have had twice the atmospheric pressure as Earth when it formed, with nitrogen as the primary component.
However, while in the early solar system Earth froze over, since the Sun was not as bright, Venus would have been fairly balmy from the beginning. In fact, given its thicker atmosphere, it would already have had a significant greenhouse effect just from the water vapor in the atmosphere.
Over hundreds of millions of years the Sun slowly brightened and more and more CO2 from Venus' interior would have been outgassing through volcanism into the atmosphere, increasing surface temperatures. For a while this would have been a slow process as dissolved minerals in the primordial oceans would have reacted with the CO2 to form limestone, but eventually due to the lack of fresh mineral uplifts the rate of CO2 outgassing would outstrip the rate of sequestering enough that a tipping point was reached.
This point came when the planet became too warm for the oceans to circulate vertically, and instead the warm upper layers became saturated with CO2 and stopped allowing any more CO2 to react with any more minerals in the water. This lead to an accelerated rate of CO2 concentration increase in the air, thus increasing the temperature in a faster loop of heat leading to increased evaporation trapping more heat, until the surface of the planet became so hot everywhere that liquid water could no longer exist at the surface.
The resulting blanket of hot water vapor and nitrogen would have caused the temperatures at the surface to skyrocket, and prevent any further carbon sequestering. Fast forward billions of years and the water has been lost while the CO2 remains.

>>11922846
Yup basically this. Venus is still cool(hot lol) as hell.

>>11922832
>Exhaust gas is gonna get between the rocks and blast dust everywhere
The rocks layer is ten feet deep, and has no dust.
>plus with the low lunar gravity, you risk launching large rocks everywhere
The rocks are the size of a human head on top and the lower layers use rocks the size of cars, they aren't going anywhere.
Actually scratch that, just saw rocks into slabs four feet thick covering a 10 by 10 foot area each and use a few dozen to build the landing pad.

In 1995, the Magellan spacecraft imaged a highly reflective substance at the tops of the highest mountain peaks that bore a strong resemblance to terrestrial snow. This substance likely formed from a similar process to snow, albeit at a far higher temperature. Too volatile to condense on the surface, it rose in gaseous form to higher elevations, where it is cooler and could precipitate. The identity of this substance is not known with certainty, but speculation has ranged from elemental tellurium to lead sulfide (galena).[83]

What a hell world.

>>11921239

>>11922913
Just needs anti spacecraft guns and it’s golden

>>11922625
>>11922724
And also dividing one working system in two, adding another fuel tanks and thrusters which weigh a lot more than a elevator which slows the whole rocket down. Not only that, adding more complexity and parts which have to be maintained and restored before every launch

>>11922909
Refuel a Tanker and a Starship in LEO, they boost onto a Moon intercept, then en-route they dock and transfer propellants (refilling the Starship and nearly emptying the Tanker). Starship can now land on the Moon and return to Earth, Tanker does a flyby and goes back to Earth passively, using its last reserves of propellant to land to be reused.
So basically, whatever number of tanker flights you need to refill a Starship in LEO, times two, plus one.

It's easy, I slapped this together real quick-like and it's 90% functional, just needs a few little tweaks plus the reusable booster to put underneath it, and of course some flight practice.

>>11923032
How else are you going to have a pressurized path to somewhere far away from the city?

>>11923037
The shape reminds me of another spacecraft.

>>11923032
Not really. Any Mars base is going to be producing way more oxygen than it needs to breath anyway since they're going to be making methalox in stoichiometric ratios but using fuel rich mixtures in their rockets (no rocket engine runs stoichiometric overall, ever. Not talking about powerhead combustion cycles, talking about the amount of fuel stored in the tanks vs the amount of oxygen). Anyway, oxygen surplus is guaranteed, and it's not like anything that leaks out is lost forever; it just mixes with the surrounding atmosphere. Mars isn't a tiny spacecraft, it's a whole planet.

isn't the customer price 50 million per launch

You don't necessarily need any. I can very well see people and goods being discharged on rovers and brought to the martian complex. Less building materials and more flexibility on transportation.

>>11923052
I don't think that early mars bases will have a huge methalox production. I always thought that first priority would be food production and building materials to expand the base and get some sustainability going. Fuel production only kicking in when an important part of food consumed and most basic building materials are produced in-situ.
Plus I imagine other gases than oxygen will need to be mixed for the interior atmosphere, so as to not burn everything the moment a spark appears.

>I always thought that first priority would be food production and building materials to expand the base and get some sustainability going
That's dumb. The first thing you need to get sustainable is the transportation architecture or the whole effort dies in the cradle. That requires propellant manufacturing. Food is not an issue to ship, one ton supports five people for two years without rationing. 100 tons supports 250 people for 4 years without any rationing, meaning a sizable facility with actual industrial capacity can be operating without any need for in-situ farming at all.
You need a few hundred people in order to get enough of an in-situ supply and manufacturing chain going that you can smelt metals and use them to build pressure vessels. Once you can do that, you can very rapidly get tens of thousands of cubic meters of habitat space to live and grow food in.
Doing it the other way around would mean having to ship all those vessels from Earth, on one-way transportation systems at great expense, and at the end of the day you'd get a fixed capacity food production unit on Mars and still need to get all the steel production and propellant production industries on their feet anyway.

Mars has great land and resources such as water, iron, aluminum, and other materials. It also has the benefit of being relatively easy to leave compared to Earth so it can be a useful stage off point for other space missions.

It has parachutes. I'm just saying it has all the parachutes and stuff but instead of landing in water and fucking up reuse, just put it down on the water. This is cause if starship was problems with human rating the belly flop, Dragon can be used to ferry the crew down.

What's your least favorite Martian quadrangle and why isn't it Margaritifer Sinus

>>11923367
They have obvious benefit Mr.noargument.
Being able to keep thousand of people alive without crippling and weighting down your spaceship with life-support mass, they'll be extremely profitably in the long term.
Think of them as the Passenger Liner of space to the new frontier, carrying thousands in multiple cyclers. With the proper technologies they would aerobrake around Mars, disembark their passenger at Deimos/Phobos transfer stations (building the space elevator) and finish their live as material or lander, if refueled they follow the incoming cycler back to Earth.
If we managed to use them conjointly with space tether we could have almost free transport, and the tethers would be useful by themselves.

>>11923034
Starlink is being launched at marginal cost, meaning it's going to LEO for $1800 a kilo, which is fucking wild.

>>11923458
Most of the weight in life support is consumables (ie food), and each ship will need to bring a large surplus of food anyway because they'll be feeding the colony.
The only thing a cycler does is let you get people to Mars if the biggest single chunk you can launch onto a Mars intercept at a time is a small capsule; you build the cycler over many years until it is big enough to house a small group of people on the way to Mars, which get launched in a capsule to rendezvous somewhere out beyond the Moon.
Starship makes a cycler pointless because Starship itself is already huge. Any small benefit you could imagine getting by using a cycler isn't worth the development and running costs of having a cycler in place.

>>11923472
Marginal cost is irrelevant for comparison with other rockets. Its good for internal cost reduction but for comparison with other rockets, the price is what matters, not the marginal cost.

No. It would need to be at least 50% to have a noticeable reaction and at those concentrations it becomes dangerous.

>>11923474
>t. oldspace
Obviously you wouldn't use cyclers early stage, you'd use it once the destination is self-sustaining in the basics, do it right and the cycler can have its own ecosystem.
Cyclers will be able to move workforce there faster (as in quantity vs time) than any future starship will be able to. You double the number of passengers aboard on each ship because they won't have to sacrifice mass for amenities.

You are not going to truly colonize Mars with space bus or plain reproduction, regardless of the eugenic fantasy with automated factory that strive on 4chan.
Do the math, assuming 25 colonist per ship you'll need to refuel 400 ships to carry 10000c and 4000 for 100000c
Now imagine 10 cycler for 50 colonist you only need to refuel 200 ship to carry 10000c and 2000 for 100000c
Even if you needed 1000 launch to assemble the 10 cycler it will stay a win. Those cycler would likely be built in orbit then launched (it is easier to plan extra tank once than to assemble something good on the run).
And we are not talking propellant production there, it would take casual nuclear propulsion to even start to offset their long term advantage.

That's the problem with Musk fanboy, they can't think LARGE or long term. They only see the cheap fantasy with the Narrative that go with it, narrative where the enemy is anyone downplaying the space savior and his undefined fleet of unfinished interplanetary space bus.

>Australia is a world leader in mining and produces 19 minerals in significant amounts from nearly 400 operating mines. Minerals are produced in all states, the Northern Territory and on Christmas Island.

>>11924023
Question, do we need “Q>1” to make a fusion rocket? Like I understand why this is needed for power production, but from an engine standpoint will it work so long as you’re producing a confined fusion plasma?

>>11924014
Usually fusion pellets are either ignited by electron guns or crushed and ignited by powerful magnetic fields, while magnetic fields confine the jet of fusion plasma and keep it pointed away from the ship. In all the sensible designs the drive's plume is actually held several hundred meters away from the ship, allowing much of it's radiant heat to shoot off into space, requiring only a small fraction of it be dealt with using a combination of highly reflective materials and radiators.

>>11924030
>Question, do we need “Q>1” to make a fusion rocket?
It helps with zeta pinch designs since it means you only need to charge up a bank of capacitors once before flight and then the reactor is self powering.

Bezos partner with OldSat companies to push out Starlink

Ok, finished fucking around with the rubbing alcohol.

End result was air intake holes at the bottom so suction doesn't cancel out some of the thrust and slow down the reaction. Also put the cap on the bottle and gave the jet a pencil hole space to come out of. Didn't really screw it on as a fail-safe so there were no explosions. Thing launched the cap 10 feet high and scared the shit out of me.

Hopefully this lockdown extends so I can fuck around with model rockets.

>>11924030
I don't think it's necessary but you're going to be getting atrocious TWR from a ship that has to lug around a second reactor even larger than it's own engine just to generate power to keep the engine going. A Q > 1 fusion rocket on needs capacitors to store enough energy for a startup shot, once the drive is running it can then generate enough power to keep itself running and recharge the capacitors as well for another startup later.

How much money does that save per launch? Like 16 million right?

>>11924076
Its about $6m a piece for fairing. So 2 fairing = 12M total. However with bit of refurbish + ship cost, the savings would be probably be close to ~$10M.

>>11924081
6 mil for both, not per one

>>11924043
"Oh no! How could they discover my plan to make cheap ass satellite?! Oh wait"

>Incoming Kessler syndrome

>>11924104
Humans for all of history on average utilize a depth of 1-2 meter. In space, There is a depth of thousands of kms.

>>11924051
Remember that launching the cap only means it will launch a cap's worth of mass 10 ft. Just doubling the mass would probably not move much at all.

So did the Late Heavy Bombardment actually happen or not?

>>11924138
Yes

>>11923659
Trying to make a hobby vehicle or just an engine? If just an engine, compressed air is the best option. Basically free, autogenous pressurization, works fine. You could even use the air to spin a turbine to pump a liquid fuel if you wanted, for true hobby rocket engine autism.

>>11924139
Is there proofs?

>>11923326
>a lot of time and effort
A boat with a net

>>11924142
Teh Moon and geochemical data from around other planetary bodies anon

>>11924142
Most of the craters on the moon date to around 3.9 Ga and so do over 20000 known craters on earth

>>11924149
yeah, just catch a 5-meter wide object parachuting in from space with a net on a moving boat. Trivial.
In reality the fairings do a whole bunch of shit to right themselves and properly deploy their parachutes and try to aim to the right place. There's a reason it's still such a crapshoot to this day, even when booster landings are basically assured.
It seems against SpaceX/Musk ethos to pay engineers to work on all that for a stopgap that surely can't be saving all that much money.

>>11924183
F9 will be used atleast until mid 2020s, so might as well save some few millions here/there. The single saving from fairings could fund 1-2 starship prototypes.

>The 40Ar/39Ar data are not the only source of evidence that has been used to support the LHB hypothesis. Indeed, the original proposal of a “terminal lunar cataclysm” (6) was based on the observation of widespread U−Pb fractionation at ca. 3.9 Ga together with nine Rb−Sr internal isochrons ranging from 3.85 to 4.0 Ga. In some ways, it is surprising that global inferences were drawn from such a small sample population, more than half of which were derived from Apollo 14 collections; this further underscores the earlier noted issue that all Apollo-era samples are restricted to only ∼4% of the lunar surface (19). Thus, these data are equally consistent with a single, local event rather than a planetary-wide bombardment episode.

More moon rocks collected WHEN?

>>11923870
I like how they're both right on the edge. there's gotta be a better way to catch these things. you can't strafe in a boat and 1 gust of wind can completely ruin a capture attempt

>>11924188
Might fly until late 2020s with the Crew Dragon contract.

>>11924203
Can't shift the boat left/right few feet. So its all a matter of precision with parachutes.

>>11924190
>More moon rocks collected WHEN?
I'd say about 2030 or so.

christ why is mars such a dumb planetlet bitch

>>11924240
OH SHIT EARTHBROS WE GOT TOO COCKY!

what's a good intro to lunar geology?

>>11924256
stealing moonrocks from nasa and grinding them up and railing that shit with some cocaine

>>11924208
NSSL Phase 2 will be launching space force shit with it into 2027

>>11924240
Imagine if Mars was slightly larger and had plate tectonics and a magnetic field...

>>11924353
Some plate tectonic theories hypothesize that even Earth isn't large enough to have plates on its own and the moon was vital in "stirring" the inside of Earth to allow for the mantle convection to make plates happen. So instead, Mars should've had a large moon or even a twin planet. Imagine if Mars had a Minerva twin.

>moon landings

All we need now is nukes in space and it's the 1960s all over again.

>ESA got it's budget cut by 3 billion euros
what the fuck man

uh oh bros!

>>11924387
Did they take the climate-monitoring-pill?

>>11924390
Nope, politicians blamed it on covid and the UK while pocketing the money.

>>11924399
So you're saying that the UK needs to restart its space program to dab on the EU?

>>11924387
yikes

who the fuck even invited eris in here?

>>11924506

Starship will be worthless if we don't use it to launch a Galileo-sized probe on a big chungus inertial upper stage to go and take a close look at Eris.

Word is that a bunch of Space Force stuff will drop soon. Some of it will be boring, other things will be more interesting like the names of the official ranks and the uniforms.

>SpaceX has a child company called SpaceX Services
wtf

>>11924112
In all fairness it was a cap with a hole in it barely screwed on. But as I said, not really expecting much from it, just a nice pyro display.

>>11924533
>not calling the child company Spacex or SpaceW
Are SpaceX even trying?

bruh
