It's amazing really, if you compare the size of the rockets that sent Apollo to the moon and this rocket that will send a satellite to Mars.

Space exploration hasn't gone throught major developments after Apollo, of course, but at least something happened.

>>11916991
The Saturn V sent 30 tons+ to the moon.
This rocket is sending 1.35 tons to mars

>>11916988
Well she is our mother.

>>11917005
You need help

>>11917002
>>11916991
Make that 40 tons for the Saturn V actually.

>>11916991
Two entirely different missions. A rocket sending a lander to the moon would still be comparable to a Saturn V if not bigger (Starship, SLS)

Mars is the elderly aunt who doesn't have much energy anymore but is happy to take Earth's children for visits and take us places. Venus is the knife-crazy high maintenance aunt with a restraining order who peeks in Earth's windows every evening and morning.

NSF just confirmed that if the Falcon 9 launch tomorrow goes off as expected, it will beat the Shuttle's old turnaround rate by two days - 52 vs 54.

Do you think SpaceX will launch something to Mars in the next launch window?

New information about the unmanned military "space station." Three companies were awarded contracts:
SNC - $439,100
Nanoracks - $389,900
Arkisys - $366,000

These awards are for studies, hence the low value. SNC is the only one with hardware readily available (pic related). Nanoracks' study contract is for it's work on converting 2nd stages into space station modules, so it might have hardware available. Arkisys couldn't be reached for contact and may have been a scam to steal money from the government.

4ASS R&D has uncovered yet another wacky propellantless sail design from Zubrin, and this one doesn't need superconductors! It's called the Dipole Drive. Itactually has some very nice advantages over our old friend the Plasma Magnet Sail, even without discarding the need for monstrously expensive high temperature superconductor wire.
>sails can be made from aluminum coated kevlar
>can be used in any direction via tacking into the wind
>can be used inside planetary orbits, and is actually strongest when used to change orbital radius or inclination in a planetary magnetosphere
>is not limited to solar wind velocity - top speed is over 6000km/s so you can use it for interstellar slow boats (although unless you've got 0.1kg/kWe fairy dust power systems it'll still take you millennia to reach that speed)

http://www.pioneerastro.com/wp-content/uploads/2019/10/The-Dipole-Drive-A-New-Concept-in-Propellantless-Propulsion.pdf

In short, it's a design for two masted EM sails made of cheap material with low power requirements most useful for "near shore" work ferrying payloads inside planetary systems, or for steering on Hohmann transfers. It's a solar schooner.

>>11917419
it's fake

>>11917419
At least shilling for Elon makes sense... but I don’t understand how y’all continue to shill Zubrin and his delusional sci fi theories

Who’s read for the perseverance helicopter to scout out a good landing spot for Starship?

Post-launch press conference LIVE now:

https://youtu.be/vX1UNIQxLhg

>>11917436
The NSF guys on the launch stream were sperging with glee about how between that and the Moxie O2 synthesis experiment we're finally getting ready for boots on Mars.

>>11917432
Dilate.

Starship needs a massive landing spot that can be determined from orbiters like MRO.

The helicopter is mostly for determine driving terrain in fine details that can't be picked up from an orbiter's resolution.

>>11917436

Could Orion dock with the ISS?

>>11917161
Luna is the formal name, just like Earth can also be referred to as Terra, the Sun as Sol, or Jupiter as Jove. Once we become a multiplanetary species it will probably start to make more sense to refer to all celestial bodies by their Latin names. Obviously if you live on Mars and you just said "the moon" then somebody would probably ask "which one?", so then you'd have to start to differentiate, Luna, Phobos, Deimos, etc.

>>11917507
Yes, Orion shares the same new standard of docking port that Dragon 2 and Starliner have.

I'm also part of the silent majority, and I think Trump has done pretty well for my industry. I'd like to have him around for another term so that programs that were allowed to exist under his administration can finish before his replacement tries to tear up this industry for their petty reasons.

>>11917502
Biden will love anybody who will pay him money, he was an incredible foreign puppet when he was VP, and he'll be a great foreign puppet if he becomes POTUS. Just because he colluded with the corrupt faction of Ukraine's government and their backers at Barisma to influence US foreign policy and Ukraine's elections doesn't mean he'd be averse to also colluding with countries adversarial to Ukraine. He'll collude with anyone who will sling him some kickbacks, assuming he is still mentally capable of colluding with anyone on anything.

The domes, vactrain, rovers, etc. I get why those look like they do, but why does the carport look like that?

>>11917606

>>11917606
Why single out the carport? Everything there is equally science fantasy. You're not going to see above ground transparent domes on Mars unless you start generating an artificial magnetosphere.

>>11917606

>>11917622
How much of this photo could be science fact though? I’m especially interested on that building with the NASA logo on its roof. Could something like that, of that large size, be built with modern technology on another planet?

>>11917669
The vehicles themselves, the rover, and the suit all seem plausible. The reason you won't have above ground structures is to avoid being roasted by prolonged exposure to UV radiation, since Mars lacks a magnetosphere or ozone layer to shield living creatures from it. You might see some of those small heavily shielded dome like structures above ground, and if the colony is relying exclusively on solar power then you'd see a lot more solar panels, huge fields of them covering much more area than the colony itself.

>>11917139
Asian twinks are shit in bed

>>11917705
And how would you know this?

>>11917709
Use your imagination

>>11917711
I don't have one.

Just saw neowise with my 4.5 in Starblast Tabletop. Looking straight into a fucking streetlight.

So cool, been waiting 10 years for a good comet. Showing it to my little brother was cool too. Even managed to convince him a satellite overhead was the booster for the amal probe. Comfy astronomy.

>>11917419
>Dipole Drive can produce 6mN/kW in interplanetary space
>6mN/kW = 0.006N/kW

>>11917638
>Saturn V thrust is 35.1 MN
>35.1 MN = 35,100,000N

So apparently if this scales linearly you shove 5.85GW of electricity through a dipole drive you can get Saturn V first stage thrust levels. The nuclear reactor in the Scorpion engine provides 14.6GWt and is less than 50 tons, so this seems feasible with highly-enriched uranium and a sail construction that won't melt.

http://www.projectrho.com/public_html/rocket/realdesigns4.php#scorpion

>>11917751
or you can just use that reactor to power an ssto rocket w/ some extra drop tanks

>>11917770
>drop tanks
The dipole drive doesn't carry propellant, which means its mass fraction is basically zero. That makes it better than the SSTO for everything but actually getting to orbit, and since you have a fucking Saturn V's worth of thrust with infinite propellant, you can just use a methalox SSTO shuttle and carry it with you.

>>11917751
The "won't melt" part is going to be the hardest part of the whole concept, assuming all the rest comes together. You might have to end up lugging your own reactor's weight in cooling equipment just to prevent the drive from slagging itself.

>>11917638
And a massive difference in specific impulse

>>11917787
>Saturn V first stage thrust levels
>reactor plus radiators is ~100t of mass budget
Totally doable. My melting concern is more the sails themselves. Maybe a tungsten mesh instead of aluminum?

>>11917067
Mahia is the most kino launch facility on the planet, this is a fact.

>>11917447
Moxie is a joke and pointless when you are electrolysing tonnes and tonnes of liquid Oxygen every day.

>NASA boondoggle shitcopter scouting landing sites

Spacex will have already sent cargo mission by the time that piece of shit is ready and its not like it can scout more than a small area anyway.

>>11917811
In the latest NASA press events, NASA has been talking about how the current rover will drop surface samples for another rover to pick them up, and load them on another mission ascent stage that will launch to another mission orbiter that will then take the samples back to Earth.

depot

>tfw Buzz Aldrin tried to get everyone onboard the Mars cycler plan but no one listened

>>11917794
Split it up, maybe? Instead of one tungsten mesh having to handle 5.8GW all by itself, use four sail pairs each of the same size with the ship in the center. Running 1.46GW across 3.14km^2 of wire mesh seems much less likely to slag the wires, especially if you use tungsten.

I think it was the point where Christianity jumped the shark, reading bronze age mythology about the creation of a flat Earth while orbiting the fucking moon. I can respect the astronauts for what they did while thinking they were the unknowing harbingers of a change in predominant religion.

>>11917885
It means they are attempting to develop ICBM technology

>>11917886
the early christians believed the earth was round

>>11917885
Any nation demonstrating orbital capability is simultaneously demonstrating ICBM capability. What this means politically is that the sanctions will continue and Iran will never be allowed to gain nuclear capability, because otherwise they'd become an existential threat to everybody else.

Possibly. It's going to be in Mars orbit for years, and Mars doesn't have a magnetosphere. Its rad profile is more like what you'd get from a deep space probe than an Earth satellite.

I genuinely don't understand how you could trust anything a religious person has to say / do. if they truly believe in this god figure / energy / whatever then you can't really trust them to make a choice for the benefit of anything other than that thing. The whole where their loyalties lie thing. It's also made worse by this entity being intangible and the followers are encouraged to try and 'find it within themselves' and listen to it. do you want the person backing you up in a spacecraft to be the type to cope by pulling themselves out of reality or making something up and convincing themselves it's right because some omnipotent being told them so?

No, it isn't gold. It's mylar foil with a thin layer of aluminum vapor-deposited on the interior side. Mylar is yellow, aluminum is silvery white, and combined the result is a gold-looking foil that reflects infrared and visible light very well. Again, there's no gold in it.

Hydrolox meme in action, folks

Martian agriculture and food supplies in general deserve more discussion. Plants are a given for taking to mars-you get fresh food for better crew nutrition and mental health,and secondary psychological benefits from the sight and smell of the plants for the crew, and also assistance for the air processing system since plants eat co2 and exude oxygen. I think they should also, even early on, take fish to mars. Seriously,why not? Keeping fish like tilapia alive in zero g seems totally possible if you make a tank correctly, since unlike animals like chickens they won't care about the lack of gravity.

the crew get a source of rich,delicious meat as well as a means to help efficiently recycle waste from their plant foods by feeding them to the fish. I think mushrooms would also be a great additional food source to take along, extra protein and they would help break down plant material for recycling into nutritious soil.

I think create a rich food environment or the colonists is far more important than we might think for maintaining emotional well-being.

>>11918045
Processing fish and maintaining the tank in zero g is too messy.

You'll want to keep fertilized eggs in cryo. Until you arrive on mars.

>>11918410

Oh look a nigger, I thought we were talking about his business model?

>>11918410
Such as energy and storage (tesla), transport (tesla), pressurised and radiation secure spaces (boring company), compact, efficient vertical farming (his brother), construction equipment (closed door talks with CAT, Komatsu etc...)?

>>11918410
>There’s more to a colony than just a cheap launch vehicle.
Like drilling an underground colony?
Like supplying and storing solar power?
Like electric vehicles that can operate without an athmosphere?
Like communication sattelites?
I wonder where that might come from...

I used docking ports to attach nuclear booster stages to a huge spacecraft in KSP. However, they eventually begin to oscillate in an increasingly violent manner that can only be stopped by timewarp. Is there any way to fix this? I have KIS, but it turns out you can't attach struts in flight.

>>11918621
Use a docking port with as close to the same diameter as the vehicle as possible, and I just use KJR. I guess some people would say "hurr durr it's a cheat because it makes vehicles stronger" but I don't see real space stations wobbling the fuck out and turning into spaghett so fuck those guys.

>>11918621

>>11918844

>>11918844
>>11918848
The North Star launcher right?

>>11918884
Yeah. Really wish they'd work on some liquid propellant engines too here, but I guess I'd have to do that myself if I ever want to see it.
Still an upgraded Andøya is better than fucking nothing.

>>11918888
You're the guy I was talking to about Andøya a while back right? Talked about the joint strike missile too? The motors on north star are hybrid, so it's close enough.

>>11918888
>putting your launch pad on a pole so you don't have to cool your methane/Lox

>>11918904
Yup and hybrid is not good enough. Not nearly powerful enough.
I mean, if all you want to do is deliver a sixpack to LEO, it's great. But you to expand like 21 of the fucking engines in 3 stages to get it there. That's not really going to cut it, is it?

>>11918910
*expend

>>11918910
Do you know what the Specific impulse is? Also kek, Zubrin is here.

>>11918923
No, they're pretty tight lipped about actual specifics, but the North Star can't put more than 10-13kg into a stable polar orbit using 12 engines in 3 stages.
That means it's pretty limp wristed.

>>11918923
>Do you know what the Specific impulse is?
>hybrid rocket motor
Guaranteed to be shitty

>>11918927
Yeah, but it's a small rocket, any payload into orbit is decent.

>>11918930
I figured, but it's probably significantly harder to make a fully liquid engine, especially at those scales. I wonder if North Star is a pathfinder, way to test the waters before moving to a bigger liquid design.

Also, any questions for Zubrin?

>>11918397
Back in 2016, the business model kind of wasn't sustainable. Spacex was establishing a capability that left everyone else in the dust, and the world wouldn't have known what to do with it.
Then, Spacex MADE the business model sustainable by bringing Starlink onto the table and becoming their own customer while building a telecom cash cow and military asset. They were talking about satellite constellations back in 2015/16 but it was all still pretty murky, and Tintin A & B didn't launch until 2018. Starlink is bridging the gap while the rest of the world gears up to properly take advantage of cheap spaceflight.

>>11918854
I don't think so

>>11918946
>but it's probably significantly harder to make a fully liquid engine, especially at those scales
I disagree, actually. Modern cheaply available stainless steel would allow someone to build a turbopump driven alcolox engine rather easily, and it'd not only be more simple in terms of propulsion dynamics (a continuous thrust, smooth burn as opposed to an inherently variable thrust that can change wildly depending on fuel grain stability and oxidizer mixing performance), it'd also be more efficient. The biggest advantage of using alcohol as your fuel is that you can simply add water to bring down the combustion temperature if need be. This exchanges simpler cooling methods for decreased Isp, but efficiency is not the name of the game here regardless. Oh, and the idea would not be to reduce the combustion temperatures so much that no regenerative cooling is required, it would simply be done so that the regenerative cooling loop can keep up with the proportionally higher amount of thermal flux per kilogram of propellant being burned that small engines need to deal with.

I was thinking about this the other day, actually. Alcohol is one of the few dense propellants that allows you to build a fuel rich staged combustion engine (and by extension FFSC also), which means higher chamber pressures could be attainable. I imagine that with the SpaceX style of development it wouldn't take more than a few years to have a fully functional and flight ready alcolox staged combustion rocket engine in the 1 kN to 10 kN thrust range, especially given modern manufacturing tech and the dial-a-temperature bipropellant.

>>11918997
>turbopump
That's the difficult part. How do you make this thing? Do you print it and then lost-pla cast it? Will look like trash. Lost wax casting? It will warp. DMLS? Expensive.

>>11919006
First of all, don't make it anything fancy. Start with a COTS pump, run it, see if it's holding up, if not order a bigger one/alter the design a bit.
>How to manufacture it
Probably cast, then mill. Warping is not an issue for manufacturers with experience. 5 axis mills aren't ridiculously expensive and they work faster than any person. The trick is to get a good work pathway so that things go fast and don't get broken.
Don't fall for the printing meme, it's not worth it in 99% of cases. In fact the one case in which printing may be desirable would be for producing a single-piece combustion chamber throat section, with embedded cooling channels. Otherwise, spin-forming if your friend when it comes to the rest of the nozzle.

>>11918196
De Grass Mower is a planetarium manager, and Elon builds spaceships and fucks alt music bitches while snorting ambien and adderall.

Zubrin thinks Fusion and people on Mars by the end of the 2020s. I can only hope.

When?

>>11919119
A year or two ago, he's been actively defending Elon on TV/etc when Elon was being skewered by the media.

>>11917141

What are some good potential launch sites in the US that are currently completely unused?

Now that Elon snagged the South Texas coast, my runners up for potential spaceports are Hawaii, the Outer Banks, coastal SC, and possibly the Maine coast as well. Any others that I'm missing?

>>11919229
Hawaii is pretty much it. You don't want to go too north unless you're specifically targeting special orbits.

Some test happening atm at Boca

>>11919229
Kinda the same as coastal SC, but I believe a Georgia coast location was under consideration by SpaceX before choosing Texas.
I'm sure there are remote enough locations on the Maine coast for rocket launching, but it would probably be limited to polar launches. I know there's been proposals for launching from Nova Scotia, which would be better though obviously not American.

>>11919229
The gulf, once you establish a launch platform and a reliably logistical chain you can slap your launch pad down directly atop the equator.

>>11919229

Just watched this video about China's space program saying fuck it and launching over populated villages... is there anything about China that's not hilariously horrifying?

Bros, do you think we’ll discover life outside of Earth within our life times? When are we going to drill down into Europa or Enceladus? I feel like these should be top priority things for NASA but we’re too busy looking at fucking stupid things like hexagonal patterns in Saturn

>>11919335
>When are we going to drill down into Europa or Enceladus?
2040s at the earliest probably? Late 2050s/2060s for the first manned presence on Europa probably, because SpaceX will be focusing on Mars for the near term.

>>11919335
>Bros, do you think we’ll discover life outside of Earth within our life times?
I doubt it, but it'll be cool if it did happen.

> I feel like these should be top priority things for NASA but we’re too busy looking at fucking stupid things like hexagonal patterns in Saturn
NASA isn't busy with that. It's hamstrung by a schizophrenic budget that changes every 4 to 8 years.

>>11919373
>I doubt it, but it'll be cool if it did happen.
Why? If there aren't any microbes on Mars, then there probably will be at least some in the outer moons of the solar system.

>>11919247

Maine coast and Nova Scotia are essentially the same, but would both be pretty solid for everything from the ISS inclination or so to polar orbits.

Obviously, you're not going to GTO from ME anytime soon, but it might also be useful long-term for Apollo-style manned launches up and over/under the Van Allen belts to the Moon and beyond.

>>11919229
Johnston Atoll

Used to be an air force base and a facility for destroying chem/bio weapons. It's a couple hundred miles south of Hawaii. No native life to speak of.

>>11919379
Two reasons. First, it seems like the conditions for the actual start of life are rare. Some of the studies about how life began that I've read about require very careful conditions. Second, at least judging from how life here works, once life begins then it spreads everywhere it can and clearly affects the environment. If life began elsewhere, then its effects on the local environment should be clear even if the live there is long gone.

I'm not an expert on this though. There could be a poor understanding on how life began, resulting in seemingly sensitive conditions necessary for it. Life elsewhere can easily function completely differently compared to life here. Lots of unknown variables. I'm not pessimistic about the search for life, I would be stoked if clear evidence for non-terrestrial life were found, but I'm just not expecting it.

Presidential Message on Space Exploration Day, 2020
https://www.whitehouse.gov/briefings-statements/presidential-message-space-exploration-day-2020/

>Soon, the rover Perseverance will launch from Kennedy Space Center, bound for the Jezero Crater on Mars, lighting the way for our brave American astronauts to one day follow.
> Along with the helicopter Ingenuity, we will test powered flight on another world for the first time, unlocking the mysteries of the Red Planet in order to one day plant our great American Flag to proudly fly as a beacon of liberty and American creativity throughout the galaxy.

Yeah, that window is closing fast.

Perseverance won't launch until the 2024 window.

>>11919603
Well, that 15 days and change to get it off the launchpad.

>>11919606
*they have. Fuck my brain today. It's just completely shut down. I've had fuck all sleep for over a month and it's catching up.

>>11919609
Forgot to mention, Perseverance will explode during launch too.

>>11919619
What makes you think that?

>>11919619
I doubt that. Atlas V has a pretty good record.

>>11919624
>>11919625
Because reality is often disappointing

>>11919304

>>11919637
Well, it's a rocket that has had 84 launches, 83 successes, 1 partial failure where the payload lifted itself the rest of the way. I'm not worried about the rocket. I'm more worried they'll fuck up and miss the launch window becuse MUH KUNG FLU or some fucking cloud.

>>11919638
the southernmost point of the gulf of mexico is like 1000 miles north of the equator

>>11919642
Atlas V is a great rocket and the launch will go well. I hope they don’t miss the window though.

>>11919648
Ah shit yeah that wasn't correct at all, you can put your launcher a shitload closer to the equator than you could get it in Florida or Texas.

bros
why dont we just launch rockets like this??

>>11919655
>>11918004
I agree but ULA needs to give up on Delta IV Heavy

>>11919037
As long as he isn't saying people to Mars via fusion propulsion he may very well be right.

>>11919670
cool space elevator bro. material sciences isn't there yet

>>11919670
you're a genius

>>11919670
It could be done, but it would be one of those megaprojects that demand a prohibitive amount of resources.

>>11919335
If we sent another orbiter to Saturn which packed a magazine of aerogel sample collectors and an on board lab (spectroscopy, chemistry, optical and electron microscopes) we could fly through Enceladus' plumes a dozen times and have the best bet out of any candidate target of finding life. Those plumes are salty, which means they're from oceans under the ice (not just water sublimating due to surface flexing) WHICH MEANS if Enceladus has any subsurface life at all we'd be almost guaranteed to at least find significant chemical traces of complex biological activity (amino-acid-like and nucleotide-like molecules).

A mission specifically to analyse those water plumes spewing from Enceladus' ocean has the greatest likelihood of finding life while also being feasible to accomplish entirely robotically. We may be able to find life on Mars by digging into some underground aquifers someday, but that's going to require boots on the ground in order to pull off, full stop.

>>11919672
It really is crazy to contemplate technological progress like that.

>>11919670
>why dont we just launch rockets like this??
Because even if you could build it out of steel and didn't need any magic active support mechanisms it'd cost thousands of billions to install and billions to maintain annually, so there'd be basically no chance of ever breaking even and actually making gains on payload to orbit compared to if you just built up a fleet of rapidly reusable rocket launch vehicles instead.

>>11919704
Crazy, and yet go back to the 1950's and our modern world would seem far more radical to them than they would ever dream.

I can't draw for shit, but I have a feeling this is how Perseverance will go.

>>11919671
But Delta IV Heavy is obscenely a e s t h e t i c, probably the best looking booster of the century so far.

>>11917922

Modern rocket designs but with Russian aesthetics, they remind me of what we'd probably have seen in the 90s and 00s from the USSR if it hadn't collapsed and taken Russian spaceflight's budget with it.

>>11919380
Latitude-wise they're basically the same, but if you want to avoid overflying land, Nova Scotia would pose a problem for launching from Maine. Any island south of Acadia would probably be fine for ISS inclination though.

>>11919866

His argument is that humans destroyed and continue to destroy Earth's nature so we shouldn't do the same to Mars. Because of that, we can live "with" Mars just to study it but not live "on" Mars or terraform it in the future because that would ruin its current pristine condition

Sure is. World record on refurb time too.

>>11920539
Damn they beat the record for the shuttle. Didn’t know the shuttle still held that record till today lmao. Y’all think Elon is on track for one-week or even one-day turnarounds? Is he going to test this with Falcon 9?

>>11920570
There hasn't exactly been many contenders for reuse since the shuttle.

>>11920570
Doubtful. Only for starlink if they do. At some point reliability trumps turnaround. Starship is gonna be the vehicle to break those one week turnarounds.

>>11920503
It’s routine at this point. It’s more notable when the first stage fails to land. If you had told me a few years ago that would be the case, I wouldn’t have believed it..,

>>11920570
they haven''t beaten it yet I don't think

I wonder if the Oberth gains would offset both the gravity losses due to going straight up through the far side of the planet, or the fact that you'd be flying through dense atmosphere for something like 1000x as long as normal.

Maybe if the tube you drill out was curved into a massive gravity turn and could hold a vacuum.

If it's a vacuum tube, maybe you could uncork the initial drop side and then ride the repressurization wave down for an additional boost.

They can have back their things which we have carefully preserved and displayed in museums if they all fuck off from Europe.
