That's why we need sundiver battlestars with PROCSIMA cannons or free-electron X-ray lasers. You could slice and dice enemies all the way out to Jupiter with sufficiently precise targeting, and have infinite ammunition to do it with.

>PROCSIMA
So was this a scam? Or has it disappeared into the classified world?

>>15063865
It's a death ray if it works, so could be either. DoD understands the Kzinti Problem.

>>15063868
Is that the one that goes something like "anything that makes a good propulsion system is also a weapon?" I forget the verbiage and my search-fu is failing me.

>>15063868
I like the word "turbolaser". Because that's what PROCISMA is, a laser turbocharged by a neutral particle bean.

I keep seeing people think that lunar landers look stupid and fake, because they look so flimsy and are wrapped in thermal foil. I guess this giant, corpulent Tintin rocket will finally look like what people expect a lunar lander to look like

>>15063899
It's the other way around for me. The lunar lander looks like what I expect from real spacecraft, while I still can't really believe Starship will be able to Buck Rogers it's way into the Moon without tipping, despite all I've seen saying it will be safe.

>>15063899
Needs bigger legs, ITS was fucking based, HLS has a shitton if excess capability, put that in making it look cool

>>15063811
Higher wind limits, they used a heap of Starlink launches to fly in winds they wouldn't launch customer payloads in and found the F9 handles them better than expected.

>>15063812
Shuttle-Centaur would have been so based, yet it was retardedly balls-to-the-wall insane. Using all the tricks to get the Shuttle to edge into space as fast as possible.

>>15063811
More internal Starlink flights = more data = more knowledge of edge cases = more operational understanding of limits/capabilities = less delays

>>15063899
You never really know what kind of inelegant-looking design compromises the final product is going to have.

>>15063871
Yes. It's from Ringworld.

>>15063941
I assume it'll have radiators so they probably don't need to wrap it in insulation? Besides that, if the normal Starship can get into space, then that one probably doesn't need to look too different either

(general dynamics 'low cost lunar access' proposal ca. 1993. two titan 4 and two shuttle launches)

It assumes a 481 isp engine...

Looks like space is back on the menu boys.

>>15063915
That's because you've had your expectations lowered by years of oldspace disappointment. You're conditioned to thing of a spaceship and a tiny single-mission unit launched at the tip of a gigantic expendable welfare stack.

>>15063919
Would Musk be enough of a memester to paint one HLS like this

>>15063973
Hey, I think the oldspace approach is justifiable for the Apollo times, since they lacked the computational power for something like the F9. The issue is that the shuttle was doomed due to the bureaucracy, and they got too conservative to try new concepts of engineering.

>>15063915
It's literally like a soda can, aside from the cargo at the top. Try to tip over a half-full soda can and see how it behaves. Also try either one of those smaller 8oz soda cans, or a long beer can if you want something closer to the aspect ratio of SS.

>>15064134
Okay well yeah sure something short and stout like the grumman LM had a huge range it could withstand, but if your Starship is autonomously landing you with a tilt greater than 20° then you have BO-tier software and you deserve to fall over. This is a huge threshold.
It’s not going to tip over.

Honestly why even risk it? Just ditch MS-22 and send up MS-23. There’s no shame in saying “better to be safe than sorry”. I don’t know how the logistics would work out though, you might need to send up two new söyuzes. Plus is it even possible to deorbit a soyuz remotely?
Either way we will know by the 27th. Yuri Borisov said the decision will be made then

>>15064233
ARE TRYING WAY TOO HARD TO BE FUNNY

>>15064277
Assuming the soyuz is found to be unusable, this will be the first time (to my knowledge at least) that the ISS has more astronauts than it can handle if they need to escape. Might be worth sending up a second crewed dragon

Katya and Anatoly are a credit to Russia and represent the very best of it, I know at least one of them has already left but I hope that they keep safe in these turbulent times and are allowed to do their reporting unobstructed.

I asked this on /x/. Can you smoke on a spacecraft? Because if we colonize another planet or nasa opens up space travel for people i can't sit in that thing for months without a cig.

>>15064609
Not currently available spacecraft, no. They're far too small, even Starship. Smoking will remain exclusively an Earth habit for centuries, possibly forever.

>>15064609

>>15064597
Anatoly is annoying but his articles can be extremely insightful and he gets a ton of scoops, even if his tweets are over the top and sometimes wrong. Katya is a strange bird, but she’s cool and she’s still in the motherland (as far as I can tell)

>>15064613
It is cramped for our astronauts most of the time? From any videos i see that does seem they case that the astronauts are all close together with only enough room to float by.
>>15064615
This is what i was thinking about. Would their air systems be able to handle it? Could we just make a separate smokers room. Maybe the area where they enter and exit by the "door" you could have a cig because that room opens up sometimes to air out.

>>15064609
I wouldn't worry about, you probably won't live long enough as a smoker to see space travel for ordinary people

>>15064627
>you probably won't live long enough as a smoker
Depends on waht you smoke and how you smoke it

>>15064627
Smoking just increase your odds of getting cancer or lung problems, you can still evade it all if you’re lucky.

>>15064625
It's not just physical volume, it's the life support systems. If the air filters clog up with particulates everyone dies.

>>15064667
Lung cancer is a cigarette thing, cigar and pipe smoke isn’t inhaled.
I’ve tried cigarettes, they taste like ash compared to pipe tobacco, and smell like burning paper

>>15064667
Smoking will %100 cause lung damage, regardless if you get cancer or not. You will most likely be on home O2 with COPD.

>>15064668
what if we someday create a star ship with large open spaces, with systems that support a lot of people?

>>15064871
This one was a bit surprising. In 1967 a lot of Soviet rockets were secretive to the point of not being publicly revealed until the 70's.
You can tell from the wings under the engine bell that the rocket here is actually a Redstone, as the US' rockets were public information

If you live in the US or some country with a pipe manufacturer, you can get a pipe for relatively cheap ($25-75), and tobacco for about $10 a pack.
Here in Finland the state seems to adamantly try and destroy tobacco permanently. A 50g pack here costs 20€, all Finnish tobacco makers were taxed to death or abroad in the late 90's, and even a decent pipe costs about 80-100€ to boot. There's only one actual tobacco store in my city, but those fucking juul stores seem to be thrice as abundant

>>15064882
Those are vanes and they were a component on the V2 rocket, which the Soviets also managed to capture after WW2. It's not a sign of spying on America, it's a result of russians at the time starting with what they knew.

>>15065196
I saw a presentation yesterday where apparently a 9m^3 mass of iron nanorods deposited in the atmosphere each year would be enough to sustain warming on Mars after 40 years seeding. The rods can be tuned to plug the gap occupied by various gases in terms of their absorbing or scattering effects (so you can trap infrared). I was surprised how small an amount of material it was.

Space gets enough funding, the problem is what gets wasted on muh legacy programs

>>15065185
250 MN is approximately a lot

>>15065236
9m^3 is a measure of volume, not mass

>>15065251
Wait until you find out about the kilogram.

>>15065251
Yes, it was a 9m^3 cube (well, obviously), the total mass of the rods depends on the packing, but I'm assuming they mean perfect packing

>>15065242
No one is going to spend that much to find vulcanoids just hit astroonomers till they think up something good
>inb4 'Not with that attitude'

>>15065262
So what exactly do the nanorods even do? If it's anything to do with terraforming it's pretty useless.

>>15065171
Go to bed Rozogin.

>>15065266
Simply extend the timeline out any time you think something is too expensive to happen. Eventually fusion propulsion and millions of people living in space will make a low solar orbit telescope trivial.

With 50% YoY growth rate, that could be $2 B per year next year

>>15065935
But more likely the number would be ~$2.5 B due to SpaceX having ~100%+ YoY growth rate.

>>15065929
It's not bad. I'd guess they're still losing money on it, and they need to replace the whole constellation every five years or so, so it's not like it prints money forever. It's kind of shit without something like Starship. The economics would be looking much better at ~3M subscriptions. The money printer is still revving up, it's not at full BRRRRRRRR yet.
But, there's no way SpaceX goes bankrupt at this point, so it's still good news.

posting the PDF here
>As part of the science goals for the planned Mars 2020 mission, two instruments, PIXL and
SHERLOC, intend to study the Mars surface at a close scale. These two instruments are
planned to be used on smooth rock surfaces that are free of dust and other particles. Such
surfaces are prepared by using a drill with an abrading drill bit; residual dust and particles
are then blown away using a compressed gas system—the Gas Dust Removal Tool (gDRT).
Early in the design process a risk of valve leakage below the vendor’s -20C rating was
identified. To mitigate this risk a parallel path was implemented: 1) qualify the valves to
operate at -135C, and 2) develop thermal control capability to elevated temperatures in case
qualification efforts are unsuccessful. While qualification efforts are ongoing, it is expected
that the valves will be qualified to an operating temperature of -135C. In the event that
qualification is not successful, thermal control has been realized via a thermally isolated valve
configuration and thermostatically controlled heaters. Thermal testing of gDRT has validated
this design and enabled thermal model correlation in order to provide more accurate survival
energy predictions. The resulting energy consumption for heating the valves at the Jezero
landing site represents a minimal impact to the Rover energy budget.

could you settle antarctlca using ISRU? wonder how much seed money you'd need to get that set up.

>>15066702
TL;DR it's the absolute worst place on earth to operate because outdoor farming, roads, liquid water and heat are unavailable.

Also, commercial activities are illegal under international law and you'll get your shit rocked by America.

>>15066702
Are we talking about the interior with mile deep ice sheets or the coasts? Coasts would be "easy", but the interior is Moon-tier when it comes to ISRU.

>>15066705
>Also, commercial activities are illegal under international law
Seems odd

>>15066724
Basically, the environment is really unique and really easy to fuck up because it's been isolated from the rest of the world for zillions of years and everything is barely alive anyway, so it was essentially declared a giant nature preserve under the Antarctic Treaty.

So only scientific activities are allowed, and those have to follow strict environmental regulations.

>>15066702
Assuming the south pole, no you couldn't. There's no resources other than water and you can't even depend on solar for energy.

>>15066705
>>15066728
That's the thing: while America has military bases all over the world, I'll bet that the one place they can't launch anything short of an ICBM at is the south pole. As long as you keep to yourself, I'm pretty sure they're not even going to be able to spy on your above ground activities using satellites, doubt there are very many CIA sats in polar orbits.

>>15066728
Or they're trying to keep people from discovering the throughway off the tip of Africa allowing transit to the interior of the continent. I bet you'd find some frozen uboats there.

>>15066705
>>15066728
>>15066732
Nobody would bother to enforce the Antarctic treaty if some country were to break it

It's a gentleman's agreement really and as soon as it's in anybody's interest to do go digging around Antarctica, they will

>>15066732
>>15066736
America are the only people who actually have decent logistics in Antarctica. The icebreakers and cargo planes that support the continent's logistics are mostly American.

>>15066740
There's just not enough energy available. You need energy to tunnel, keep everyone warm, etc... Since solar is impossible half the year, you need to find Uranium or fossil fuels, which is unlikely. Even if you did, I doubt it would be enough to actually provide enough energy for any kind of worthy ISRU.

The better question is what kind of rovers do we land now that the mass budget is 100 tons instead of like 20 kilos.

Sure, eventually manned ones, but the first couple of starship landings on Mars are probably going to be unmanned, just to ensure there aren't any issues that would kill a human crew.

I'm picturing like a monster truck with a bunch of quadcopter drones to help navigate the terrain around it. Use compressed CO2 to de dust the solar panels, or just use nuclear like a chad.

>>15066930
we dont rove anymore. now we dump 100 tons of solar panels in spite of zubrin's seething

>>15066936
What about a rover that sets up little solar farms and uses those to charge batteries, and then all the other rovers use that as a little gas station? Better yet, do a closed cycle where they electrolyze water into oxygen and hydrogen and then fuel cells on the rovers turn it back into water.

From there you could rove everything.
