Red Dragon data page just updated, is it happening?

https://catalog.data.gov/dataset/low-cost-mars-sample-return-utilizing-dragon-lander

>>11960599
sample return? so an astronaut will walk around and grab the samples?

>>11960537

>>11960599
It would not surprise me if the flawless success of Crew2 Dragon compared to the abysmal failure of Starliner caused NASA to reconsider their original judgement about the utility of Dragon as a space vehicle. I find it interesting as well that they actually include retropropulsive landing as one of the requirements for human rating, in spite of originally showing zero interest in it as an alternative to ocean splashdown.
>"For Earth orbital operations, retropropulsion thrusters (Super Draco) perform both the launch abort and the precision soft landing functions necessary to qualify it for crew transport to/from LEO."

>>11960618
No humans needed. The sample container gets yeeted from Mars into orbit around Earth and then another Dragon picks it up.

CRISPY bobendoug when?

>>11960628
but it says dragon lander, so it'll land on mars

>>11960633
Yes, the Dragon will land, carrying a smaller spacecraft inside itself. The capsule alone does not have sufficient Delta-V to land, take off, achieve a capture with Earth and then tuck itself back into a stable orbit. It would be kinda like the lander for Apollo, it will stay behind.

>>11960633
That's the first one, there are no humans in it. Dragon is launched from Falcon heavy, it lands on Mars, collects samples, ascends, and then sends a Earth Return Vehicle into high earth orbit. The Samples then get collected by another Dragon which takes them home.

Does anyone know how much a full Starship/Superheavy stack costs? We know the engines are $2 Million apiece now, but are planned to go down to $1 Million in the future. We also know that Elon told us the steel costs $3/kg, and the vehicle masses 300 tons in total of SS/SH dry, so that’s like a million dollars there.

>>11960537

>>11960661
Marginal cost of vehicles will probably in $40-60M.
Marginal cost to operate the vehicle will probably be in $2-5M
Cost for customers will probably be in $30-50M a flight.

>>11960677
>Cost for customers will probably be in 30-50m a flight
More like 10-30m a flight

>>11960686
They'll lower it as they get more flights.

>>11960661
I ballparked about 200-250 million for the whole stack a while back, accounting for raw material costs, the costs of all engines (assuming 2 million a piece), and the cost in terms of wages for, if I recall, about 300 people directly involved in the construction of the vehicle. It will go down as multiple vehicles are made obviously, and since they've just received some industrial assembly line armatures I'd assume to do high quality welding or something like that the actual cost in man-hours and thus wages will also go down. It's also hard to tell how much the reentry system will cost, so that figure is completely up in the air.
I think once Starship/Superheavy is fully mature as a design it won't cost much more to build one than it currently does to build Falcon Heavy, about 150 million a piece.

>>11960652
Meanwhile Perserverance's sample tubes stay on mars and get buried by a seasonal dust storm, amazing.

>>11960686
I sort of doubt it. maybe later, but early on they will need money and lots of it since they just spent a fortune developing starship and need to build up their fleet. price will be what the market can bear so maybe 10-20m less thatn going rate for government launches, and then 50% off for bulky scientific payloads that normally would have trouble affording an expendable rocket? advantage of significantly larger payloads, both weight and volume too

>>11960689
>>11960701
they will be making a ton of money from starlink anyways

>>11960700
Don't worry, someone will will collect the samples shortly before Perserverance gets put into a space museum on Mars.

Has anyone made a cost estimate for the 18m Starship? I'm more interested in how it compares to the 9m Starship in terms of cost per kilogram to orbit.

>>11960701
Keep in mind Starships dev cost is pretty low all things considered. Starship is made of cheap materials and is made using COTS equipment.

>>11960695
While I never factored in the wages of the workers, I highly doubt it would cost $150 Million per the entire stack. Also I’m pretty sure that Falcon Heavy is like $60 million in terms of build cost (citation needed) based on the leaked Falcon 9 first stage price.

But yeah it’s amazing what switching to Stainless Steel will do for you.

CARBON FIBER STARSHIP WHEN AAAAAAAAAAAAAAAAA
STEEL IS NOT FUTURISTIC AND NOT FUCKING OKAY WE NEED CARBON FIBER COMPOSITES AND ALUMINUM AND TITANIUM

>>11960758
OH N-

>>11960754
>While I never factored in the wages of the workers
That's usually one of the biggest drivers of cost in aerospace.

>>11960768
Yeah. Do you think they’ll automate Starship production a la Falcon 9? Right now the workers are pretty in specialized so they don’t charge SpaceX out the ass but I can see that cost going up.

Also will Starship always have those bands? They look cool but most of SpaceX’s tenders are smooth.

NSF stream started https://www.youtube.com/watch?v=PqS3IzEz8Jk

>>11960772
Well, they've been buying proper industrial armatures from Kuka, I believe they'll be using them for assembling the rings and domes. It wouldn't surprise me if they switch to stir welding at least for joining the strips of steel into rings and creating the domes because the welds are linear, with normal fusion welding for the horizontal welds. An armature can be much more steady than a human and so for those long linear welds as long as you build systems to hold those stacking segments in place you could substantially improve both assembly speed and assembly quality.

>>11960817
>stir welding
there is absolutely NOTHING more sexually arousing

>>11960772
God dammit I typed out a whole response but capcha called it spam. I'm on my phone now so I'll try to summarize what I typed earlier:
>Physical mexican welders are temporary; its so that they can quickly test new welding techniques and materials
>Once they decide on all the factors, it will be as automated as possible (Elon mentioned wanting college students to be able to run the automated machines to build Starship... lots of people here on /sfg/ compare it to the Model-T
>The final design will still have those rings yes. But it looks surprisingly good. Pretty close to the renders

https://www.reddit.com/r/SpaceXLounge/comments/hs92xb/i_present_the_spacex_starship_and_super_heavy/

>>11960830
It's really quite good for manufacturing big pressure vessels, the biggest welds to create a rocket's tanks are linear and ideal for a stir welder. The only major issue is that it leaves a hole in the piece of metal, so you'll always need to finish the piece with conventional fusion welding. Still, the tool head is only like an inch or two across so that's a much smaller point for failure than normal fusion welds, especially made by humans, which (unless your welder is a veteran) could have multiple weak points over the whole length of the weld. You can simply use another disk of steel and a normal torch welder for that, or you can try as much as possible to have the stir welder's exit hole line up with a larger hole you're going to cut anyway for plumbing or a pressure release valve, so you can make the whole actually do some more work for you and cut out or simplify another process further in production.

>>11960831
How will Starship handle RCS? I assume it will use some voodoo magic and use methalox as well? It would seem weird to rely on a monopropellant that can only be made on Earth (although it might be able to use hydrogen peroxide? Idk, I haven’t heard much about Starship RCS)

>>11960831
why dont they just make starship out of glass??

>>11960846
I read that Elon believes that Starship will just use cold gas for a while. It’s simple tech and we know how to use it. Remember that a Methalox thruster is basically just a little engine in and of itself.

I could be wrong though.

Like carbon fiber, you run into the issue of needing ginormous sets of molds and tooling.

>>11960854
>2020
>not milling your rockets
NOT GONNA MAKE IT

>>11960846
Last I heard they were just going to make a smaller LOX/CH4 pack which will feed from the autogenous pressurization system. This would be sensible, especially if they're going to go with the Moonship plan of also having a set of smaller vernier rockets for Lunar landing which will also feed off the same propellant. Might as well have a system that uses all common propellants as long as you're using autogenous pressurization.

>>11960865

>>11960745
Multiply propellant load, structural mass, number of engines, and payload mass by four
Logistics costs stay roughly the same, construction should cost less than 4x that of 9m starship, vehicle longevity (number of launches before retirement) should be higher due to gentler reentry enabled by the altered proportions of 18m Starship (it's more squat, since it's twice as wide but not nearly twice as tall)
Overall 18m Starship probably provides mostly a logistics advantage rather than a cost/kg advantage, since pretty much any other increase in technological capability that makes 18m Starship cost significantly less could also be applied to 9m Starship with equal effect. That being said, the logistics advantage is nothing to scoff at, since a mere two flights of 18m Tankers could refill a 9m Starship enough to perform a Mars mission, rather than requiring 8 launches of the 9m Tankers.

>>11960865
>>11960854
Goddamn that looks mass inefficient as fuck but it’s probably strong too

>>11960865
>NOT GONNA MAKE IT
NOT GONNA MAKE IT cost 10 billion dollars per rocket*

>>11960888
The milling is actually to make the otherwise homogeneous blocks as mass efficient as possible while retaining strength, the downside is that it's insanely expensive, time consuming, and wasteful of material. As soon as there are more finely optimized extrusion heads supersonic deposition prooonting will become a superior solution because the piece can retain all of it's normal strength but there's very little wasted material, the process is much faster, and the build time could be a matter of days instead of a matter of months.

>>11960849
>I read that Elon believes that Starship will just use cold gas for a while.
Is it going to use nitrogen or methane for the cold gas? Nitrogen is more commonly used and SpaceX already uses them, but methane would simplify resource logistics.

Quantized Inertia man now claiming the Madrid team is seeking a patent for their 0.1N/kW thruster before publishing results.

>>11960888
actually, it's not only stronger, but also more mass efficient AND cheaper (potentially)

http://www.esa.int/Enabling_Support/Space_Transportation/Smart_manufacturing_cuts_cost_of_rockets
https://gameon.nasa.gov/advanced-near-net-shape-technology-annst/

>>11960904
Methane or CO2 can be retanked on Mars so probably one of those.

>>11960758

https://www.youtube.com/watch?v=MKMG-FdCGtM

>>11960941
Sooooo why isn’t SpaceX using it for Starship?

>>11960963
Way more expensive and it was slowing down the design/testing process according to Elon

>>11960963
Because it is not cheap to mill a smaller run of vehicles. Milling only becomes cheaper when there is available industrial capacity to crank out tons of them in short order, but in most cases other manufacturing methods are much cheaper.

>>11960847
Wouldn't the sound it makes shatter itself?

As much as I like to make fun of them, Roscosmos seems so comfy. They are all friendly people. Will they have any stake in Artemis other than a gateway module? I don’t like the idea of throwing them to the curb and watching as they share technology with China

>>11960974
after multiple starships are launching per day, so probably 2023 at the earliest

>>11960989
I'm sure Russians make fun of burgers on the same way. It's all friendly banter. The reason the US is slowly cutting ties with Russia in space operations is purely political and not grounded in any reasonable logic. Unfortunately but inevitable.

>>11960846
Cold methane gas held at high pressure in bottles ('cold' just meaning it doesn't react with anything to produce heat, you could store it at room temperature if you wanted). Simply open a valve and whoosh, you have thrust. It's not efficient, a bit better than the nitrogen thrusters that the Falcon 9 first stage uses, but it works.

Later they do want to do hot gas methalox thrusters, which would work by venting gaseous methane and gaseous oxygen into a chamber to be lit and burned, generating much hotter combustion products and thus more efficient thrust, still only around 300 Isp probably but that's a hell of a lot better than the 60 or 70 or so that cold gas gets you. These hot gas thrusters aren't necessarily REQUIRED, they're simply an obvious upgrade to make once Starship is operating that will make it more capable.

>>11960992
Damn I hope the russian alliance stays strong in the future. Not trying to riff on them, but do they even possess a soyuz or other launch vehicle capable of deep space flight? I would love to invite them to gateway and let them plant the flag in the Moon. But yeah you’re right... way she goes...

Boeing shouldn't get that much amount of money, and the fact they do is the greatest indicator of political corruption and lobby.

A Boeing rep is sleeping with an american senator

>>11960992
It didn't have to be cutting ties, but the US is trying to regain launch independence, there's no need for a chilling of relations except that Russia was absolutely drilling the US governments for seat rental. Now that the Russian space program has competition for seats they've simply thrown a tantrum and partnered up with China instead, who are behind them in space projects rather than continue to work with the US.
Now we can't work with them easily because their partner Chang steals every trade and tech secret that he's allowed to spend ten minutes with.

>>11961006
Well Russia plans on building Angara A5V, a variant of their “active” (hasn’t flown since 2014) Angara 5 vehicle which uses a Hydrolox second stage to place components of a lunar lander in lunar orbit.

Russia is also building their PPTS vehicle which is basically a Russian Orion. Its planned to fly in 2024.

So yes, Russia is building their vehicles for their moonshot. However they’re retarded and are also building the Soyuz-5, which is basically a single stick version of the Soyuz.

>>11961023
no

>>11961023
she's a based old granny, no bully

>>11961018
Does NASA have the capability to establish an "us vs. everybody else" kind of mentality? Maybe if JAXA steps up and becomes a big player. I just think its dumb to let China and Russia (and the cucked European space agency) work together for Moon bases while we try to compete all by ourselves. The problem isn't necessarily Russia, as butthurt and prideful as they are. The problem is China, who claim they want to work together with other countries but in reality just want to steal shit

>>11960989
I'm glad I'm not the only one who thinks this. I really hope that Angara and the Federation capsule works out for them. Space just won't be the same without a strong Russian presence.

>>11961041
NASA doesn’t but the USA does. SpaceX BTFO’d the entire commercial launch industry of the world, and once Starship flies itll put the USA ahead of the world for years.

Blue Origin too.

>>11961033
WTF is going on around the world. All the big countries are gearing up for a "race" to the Moon... except everyone is doing it so randomly. The Saturn V and N1 had clear goals. This time everyone is building shitty rockets with no real end goal

>>11961041
ESA is working with us. They're on the Artemis accords.

>>11961039
Rockets are a pretty masculine interest, and trannies tend to use "gal" and "girl" tu assure themselves that they're a real woman

>>11961055
Commercial launch providers and other space component makers are making things cheaper so programs are more likely to ramp up. There's so much to explore on the Moon I would love to have a bunch of rovers just running long term missions up there

>>11961062
I think you're over-analyzing things here.

>>11961033
>So yes, Russia is building their vehicles for their moonshot. However they’re retarded and are also building the Soyuz-5, which is basically a single stick version of the Soyuz.

With all of the crazy crackpipe iterations of Soyuz that they've been cranking out lately, I'm fully expecting that within the 2020s we'll see them throw out a Soyuz variation with a Falcon 9-style flyback first stage and strap-on boosters.

>>11961062
to be fair they lived in the town wayy before spacex came along so i'll give them the benefit of the doubt

>>11961041
NASA? No.
An upsurge of private space companies across the US? Yes.
If the federal government simply promised to pay out fixed contract prices for accomplishing certain goals, and made the process both legally and fiscally more streamlined, the private industry of the country, gimped as it is by pseudo-socialism would still easily outcompete the entire rest of the planet for speed and volume of space innovations.

Honestly I have no idea. If I was Russia I’d just commit to refitting modern-day Soyuz to be able to leave lunar orbit, and just stick with either Angara or Soyuz-5 none of that “hey let’s build both” mentalities.

ESA is cucked beyond belief though. They’re unmanned missions are awesome but they’re literally decades away from even building a manned LEO vehicle. They were closer when they built ATV, but stopped.

China is doing fine, but they’re moon plans are still really unknown and probably far into the future. We know their knew lunar capsule passed its initial tests, but Long March 9 - their Saturn V equivalent - is slated to fly “in the 2030s”.

>>11961054
People in the old space were more interested in making a career than making something fly.

"Ok, so this rocket is going to cost a trillion dollars and take 30 years to make"

30 years is how long a baby boomer would work before retiring, the trillion dollars is just free money for them.

The Falcon Heavy was, more than anything, a big "Fuck you, boomer. Look at what a 47 years old manchild can do while you rent-seek." Just look at how Blue Origin has fuck all to show and how what the other companies have to offer is the same tech form the 80's.

The simplest option would have been to dust off the designs for the lunar Soyuz from the 60s that was supposed to fly on the N-1, and instead upgrade it to fly on the Proton M, while using the experience they gleaned from decades of Salyuts and Mir to handle rendezvous and docking with a Soyuz-sized lander in Lunar orbit that was launched there by a separate Proton M.

Yeah Russia is a mess. They are caught up in a weird position where they are too prideful to retire any of the old rockets, but too broke to come up with anything new. I know they had plans for a methalox soyuz. Wish they would do that

ESA is cucked and gay. I know they signed the Artemis accords but last I heard, they have decided to work with China.

Speaking of China, they are very interesting. They have ambitious plans for a Moon base. We shall see what happens.

All valid points anon. Although I should say NASA is just as retarded right now. At least the US has an ever-growing population of private companies. If Jim were to hypothetically get fired and some new guy decided to ditch private space, NASA would turn into a laughing stock most likely

>Just look at how Blue Origin has fuck all to show

I still maintain that Blue Origin has the same problem that Lockheed does, where it's easy to shit on them because the F-35 is so underwhelming, but at the same time they've actually done lots of really cool stuff over the past two decades at Palmdale and the skunk works, all of which is unfortunately under wraps.

Blue Origin doesn't need to adhere to any DOD classification rules, but nevertheless they're every bit as secretive as a major defense contractor. I'd love to see what they're actually doing behind closed doors.

>>11961150
Speaking of Proton...

Whatever happened to pic related? Shit was cool at the time but I guess it was cancelled.

Also Angara is really cool I just wish the damn thing flew. What’s it like to be a Russian space fan? Do they cheer on SpaceX? Are they self aware to how shit Russian Space Bureacracy is?

>>11961111

>>11961170
I could have this completely wrong, but a lot of people on /sfg/ talk about how either Proton or Angara (or both?) were originally designed in the Soviet-era out of the Ukraine. Now that ukraine is independent I don't think they have a huge access to the technology

Also yeah I'm curious about Russian space interest. Especially what they think about america

>>11961170
they're not allowed to use hypergolics on Kazakhstani soil, so they can't launch it

>Blue Origin is shooting themselves in the foot by being so secretive.

Blue Origin's greatest strength and greatest weakness are the fact that the only person they need to impress is Bezos himself, whereas SpaceX was much more poorly capitalized early on and had to rely on PR to keep the cash flowing.

It's easy to shit on Blue Origin given SpaceX's relentless openness and their myriad successes as of late, but remember that they're for their first orbital launch vehicle Blue are jumping straight to a methalox booster that's bigger than Proton or Delta IV Heavy and has a flyback first stage that's big enough to be part of the Saturn family. They may not have much to show for themselves, but holy shit they're ambitious, and even if Starship beats them to orbit, their first orbital vehicle, ever, will be the second most advanced and capable launch vehicle on the planet.

>>11961221
Starship and all future deep space vehicles probably ought to uphold the naval tradition of having sex segregated quarters and heads, with somebody taking the night shift on watch at each side of the lock. Mixed sex submarines haven't exactly had a glamorous track record of proper behavior and I don't think deep spacecraft will be any different, considering you could easily be spending more than half a year in a cramped steel tube with your fellow crew.

> Blue Origin's greatest strength and greatest weakness are the fact that the only person they need to impress is Bezos himself, whereas SpaceX was much more poorly capitalized early on and had to rely on PR to keep the cash flowing.

Couldn’t have said it better myself. While Blue has infinite money, they also lack the drive or desire to optimize their vehicles for specific timeframes, contracts, lower prices. They’re operating like an OldSpace company.

>>11961281
Only the upper stage. The booster stage uses LNG and Lox.

Imagine if SpaceX just got the funding that Boeing, northshit Grumman and lockfag martin got, imagine bros. Fucking old space will be the end of us all

>>11961339
Excessive funding is most of their problem though, more money often doesn't create more quality, and even inversely can encourage poorer quality and less innovation. It would be interesting if somebody asked Elon how much money would he ideally like to have for Starship and the Falcon projects, but in the end as long as the money is "enough" that's all a company should get. We should be encouraging leanness in our industry.

It got cancelled due to Khrunichev collapsing. It has been razed to the ground by a gang of "top managers", in particular Komarov and Kalinovsky, under the excuse of moving the production from Moscow (an expensive city) to Omsk. Can you imagine what it's like to transfer the entire production cycle that worked like a clockwork, to another city? The result was predictable. To add insult to injury, they stole about a half of the govt bailout package Khrunichev got after this. I can write a lot about it but I doubt that anon in a spaceflight general is interested in Russian corruption schemes.
Kazakhstan, SpaceX, or anything else had little to do with it. (although it's true that Kazakhs complain about hypergolics a lot)
>Also Angara is really cool
No, it's not. It's a rocket designed for 90s/early 2000s when everyone bought the modular meme, which turned out to be a, well, meme. It's a case of a superior launch system being replaced with an inferior one. Khrunichev is a perfect lobbyist, along with KAMAZ and Sukhoi, so they just got all the contracts while cockblocking others. It's fairly similar to Boing, just not that large and much more decayed after the disintegration of the country and the economy, and the following chaos in 90s.
>What’s it like to be a Russian space fan? Do they cheer on SpaceX? Are they self aware to how shit Russian Space Bureacracy is?
No, of course not. We are all faceless communists and like seeing our program getting destroyed in the name of glorious Mother Russia. No, we don't know a thing about damn Americans, and wish them death. Heil Putin. Cheeki breeki, cyka blyat etc

We also got a spaceflight board on dvach since ~2012. It's slow but we actually tend to discuss spaceflight with less shitposting, as long as the board is not being infested by our /po/ltards. (thankfully, they have a short attention span)

My rover at Minmus rolled downhill and the antenna got broken. I was able to turn it upside again thanks to the handy extensible magnetometer boom.

I can still control it via relays, but cannot transmit science. Bigger relays didn't help. Why is CommNet this bullshit? Should I just ditch the vehicle?

Tiny payload, and on mars the atmosphere is thin, and the gravity only 1/3rd of what we have to overcome on earth.

>>11961992
Compared to Earth, the much reduced surface gravity of Mars makes SSTO vehicles pretty easy to make.

>>11961993
>literally every scientist
are you sure

>>11961992
You have to remember that you need to find a way to get the return rocket landed onto the planet first. That itself is a whole engineering challenge that gets exponentially more difficult and costly the bigger the return rocket is. How does NASA get an ICBM landed on Mars that can load a payload on top of itself and refuel?

>>11961992
Small payload, lower gravity, lower atmospheric density. You don't need a big rocket.

>>11962012
MARS VENTURE STAR WHEN

>>11961981
This little rover climbed to a 3k meters mountain and has 2 biomes at hand. I'd prefer not having to launch any more rockets at Minmus, that inclined orbit is a pain in the ass, and currently I don't have any contracts there to justify the effort.
If it cannot solve this problem realistically in game, I will probably just turn off CommNet in settings to send the science. It doesn't make any sense that you can control a craft live, which would require a live data stream, but you cannot send small chunks of sciemce under the same conditions.

>>11962024
You would need a nuclear ferry/shuttle to take it to mars and the current NASA is obsessed with destroying Von Braun's legacy.

>and the current NASA is obsessed with destroying Von Braun's legacy.

>>11961992
ICBMs are solids, much less efficient than liquid boosters.

>>11961992
Because the payload is very small, it's just a tiny sample return capsule with some thermal protection and a small parachute. Delta-v requirements have little to do with it since it needs to both reach the low mars orbit and launch itself to the trans-Earth orbit.

>Aren't ICMBs the height of a 6 story building?
NOTS-EV-1 was just short of one ton total, and had the delta-v to reach orbit, despite being all-solid with shit Isp. (but never did since it was 1958). The catch was that it carried 1kg max.
SS-520-5 is 3 ton with the 4kg payload.
Lambda-4S was about 10 ton total, while carrying 26kg to orbit, also all-solid.
Electron is 12.5 ton with 200+kg payload, although it's cryogenic.

>>11962068
Many are hydrazine/N2O.

>>11962072
Yeah, really old school ICBMs used to be hypergolics, back when warheads were fuckhuge.

How would you plan to live on Mars?
>>11962063
Oh, they would. There's a reason they're shilling divershitty.

>>11962021
>lower atmospheric density
atmospheric losses are almost negligible on Earth as well anyway, it's a very small percentage. However, the smaller the rocket, the higher the percentage.

>>11962246
They never said and it felt inappropriate to ask at the time. My guess is that my interview skills are lack-luster, and I've never been with a project to completion (and thus my experience is limited). It must not be something really bad because I managed to get by three interviews for that particular position. Also, it's recent so I'm sure it won't be fruitful to apply for that position again so soon.

It's just frustrating to get deep into these interview processes only to get turned down at the end.

Shouldn't there be shifts in that case? No need to force someone operate for longer, increasing the chance they make a mistake.

>>11962334
they could if they wanted to. BO and Boeing have corporate-employed astronauts iirc

>>11962334
They partially do. They train the astronauts on how to operate the Dragons. NASA takes care of the physical and science related training. SpaceX will probably do full training for paying customers for their private missions.

>>11962211
I did the KSC tour when I was a kid.

>>11962338
They have shifts. But they don't have a backup person that takes their place for 30 minutes so they can step away to eat dinner.

>>11962338
They answered it already 8-10 hours for hawthorne, but uncertain for mission control itself. The stream itself has been running for 5+ hours. So they've been there for 5 hours straight. And its not like they just came into the building 1 minute before the stream went live. They've likely been there for few hours for pre-undock checks. Now that the Bob/Doug went to sleep, shift changes will happen soon. Another 8-10 hours of shift will take place.

IIRC NASA astronauts were always "cowboys". Example: Apollo 16 where Charlie Duke spontaneously did a high jump just to see how high he could go. He ended up landing on his back, nearly damaging his life support unit, and scared everyone involved to death. He made it to 4 feet high though.

What about a machine pack that turns regolith and nearby resources into a fully functioning town?
Tower with harvesters that strip mine the area and constructors that turn it into a colony town with everything needed. It comes with built in nuclear reactor for combined heat and power and packed with prefab complicated machines like MOXIEs and lights

>“We need to get that funded 100%,” NASA Administrator Jim Bridenstine said during a media availability at the Kennedy Space Center July 29, referring to the HLS program. He argued that getting that funding for developing lunar landers for astronauts was a bigger challenge that building the landers themselves.

>>11962499
I'd assume so, since you'd need to account for that before flying the thing anywhere. If I'm not mistaken it uses Dracos for RCS, and since they can throttle quite deep I'd imagine that the RCS on the lighter side of the capsule is just slightly throttled down.

So when is the next burn? Or at least when are they supposed to wake up? I guess I need to hit the pillow because apparently I've forgot.

>>11962704
I think they just finished their last burn while they are currently asleep. They are probably going to wake up around 5 AM EST to prepare for the landing

Splashdown is on Sunday afternoon so now's the right time to get some sleep

>>11962684
The tables have turned, now the villagers are eating the rockets.

>>11962708
Nice, thank you.

>>11962708
>Apollo: alright boys the computer blew a vacuum tube, time to break out the slide rules and joystick to burn home
>Dragon: yeah dude let's nap through it

SpaceX just announced the final "phasing" burn is actually set for 20 min from now - this will align the Dragon's orbit with the landing site

https://youtu.be/zMsxviPT2Cw

>>11962718
Have we heard what a burn sounds like yet from the internal dragon cam? I hope it makes a noise

>>11962719
Nope. I followed the entire launch stream and none of the burns could be heard. SpaceX is not currently broadcasting the Dragon's audio since the crew is asleep and "signed off" comms for the night.

>>11962719
>ha ha Dracos go brrrrrrn

So they're not landing today?

>>11962726
They are landing on Sunday afternoon, over 12 hours from now. They want the crew to rest first before a busy day.

>>11962718
Yeah, I thought I remembered that there was to be a burn soon. Good thing I'm slow at going to bed too.

>Bob hoping for a weather delay to eat the contingency snacks

>>11962731
>Mission control, this is Doug Hurley. Can we get the go-ahead to land? Bob has eaten all the snacks and he's looking at me weird. He keeps licking his lips and muttering to himself.

>>11962722
Is this like, some sort of strawman of people who like SpaceX launches?

what are they using for the burns? superdracos?

>>11962747
They just mentioned they are using the SuperDracos.

They just announced the final phasing burn is complete and nominal. The next burn will be the de-orbit burn on Sunday afternoon. Crew asleep.

>>11962747
>>11962755
I thought they were just using the Dracos?

How does one determine the Qibla (Islamic Holy Direction) to face from any given point in a Hohmann transfer orbit from Earth to Mars?

Asking for Al-Amal and future Muslim martians.

>>11962777
As long as you're facing in the general direction of Earth, you're probably fine

>>11962786
It's more of an intellectual exercise. How does one determine the exact direction of the Kaaba while on the way to Mars?

>>11962777
>bowing to a literal space rock
>while being in space
Just choose a closest asteroid and be done with it, they're all the same

>>11962788
You'd want to know which side of the Earth is facing you versus where the Kaaba is, so you can offset by a tenth of an arcsecond or whatever from dead on Earth to the right bit of Earth.

>>11962791
>tenth of an arcsecond
Simply breathing will throw your aim off more than that by two orders of magnitude.

t. /k/

>>11962777
inshallah, facing towards Earth should be enough. It will look like a blue star from Mars' surface

Does Dragon keep the radio link through TDRS during the reentry blackout?

>>11962806
nah, plasma fucks up comms

just noticed you could see stars in this frame, pretty cool

>>11962817
better one

Who else tired of the attitude in the reddit spacex subreddit? Especially the starship thread.
Post something even marginally negative? Massive downvotes.
Say "I'm not really confident about the legs"? Get a barrage of replies "oh I'm sure spacex engineers haven't thought of that".
sfg is much more comfy if you ignore the poltards

>>11962916
Lmao fuck off reddit nigger

>>11962822
Those aren't stars, it's just camera damage from radiation.
You need to reduce the exposure much more to see the stars.

>>11962919
Mommy I'm so kwel look at me

>>11960661
A manned variant will easily cost around $500 million or so (this is including wages etc.).
Cost per launch for the manned will be around $30-$40 million.
Source :my brother interned last winter, these were the internal estimates.

>>11962916
The reddit is mostly just for photographs, Elon tweets, and media articles.

>>11962916
r/SpaceX is trash, lounge is a bit better, masterrace is the most norminal SpaceX subreddit

>>11962916
>if you ignore the poltards
Fuck off and stop starting shit, retard. There was barely any political discussion in this thread and you're literally from Reddit.

Why SpaceX so depression these day? No loud cheer, no big crowd, everyone looks like a robot no emotion...so sad.
Even ULA is a lot better to watch.

>>11962963
that's good
the shouting is getting annoying
besides, no crowds or fanfare avoids the awkwardness when shit fails

>>11962476
I forget the rest of the song

>>11962925
that's a sixfold reduction in cost, right?

>>11962202
Pic related.

>>11962963
>No loud cheer, no big crowd
corona-chan did this

>>11963013
Anon. Calculate price per seat.

>>11963065
no, this was per-launch not per-seat

>>11963069
Yes. But calculating cost per trip of a cruise ship versus a row boat is fucking stupid. I know it seems legit because it‘s actually still cheaper now. But it‘s still a dumb metric. Real price reduction for anything that matters will be several orders of magnitude if the reusability works out completely.

>>11963076
then is it for the ~20 person dear moon luxury yacht, the ~100 person Mars vehicles, the ~5 person HLS system, the ~1000 person point to point vehicle, etcetera

we haven't had these in a while

Is sn8 going to be a full sized build?

>>11963107
Every single SN has been a full sized build. Just without nosecones.

>>11963093
Is this just a test article for the new steel or is this going to be set up for 20km hop or something?

>>11963118
20km hopefully

>>11963093
Jesus, the flap/wings look so shit.

>>11963122
*20km explosion

>>11963137
Still progress.

>>11963141
N1 style.

Why is literally every thread on /sci/ except this general some shitty bait thread involving some extremely dumb question or other type of bait designed to cause pointless arguments? If the whole board was shit then it would make sense, but this garbage board somehow manages to maintain a normal general in the middle of all that shit.

>>11963320
These threads get derailed all the time too.

fuck urf

>>11963320
Because /sfg/ isn't the usual /sci/lons, it came from people wanting to shitpost about space and was the only place they could put it. Most of /sci/ is rebbit-tier cancer.

I saw this, it's at the Science Museum. Nice museum, highly recommend. Was surprised to see such a historic piece of hardware there, had no idea. Has a lot of interesting British space hardware too.

They have that entire spare black arrow suspended on the ceiling, it's pretty cool.

There's something more exciting around the horizon.

What is the number on the NASA stream? Some might be watching both simultaneously with one muted but it's still interesting.

at least things are still more on track than they ever have been since Black Arrow was given up on

>a mile and a half per second
That's what you get from mixing mph and fps.
