Suppose in an alternate universe, Elon chose to colonize the moon instead of Mars. Would it be possible?

Warp > Fusion > Lasers > Orion > Nuclear > Thermal > Methalox > Propalox > Kerolox > Ion > Solid > Hydrolox

>>12804614
I really hope they pivot into the space-tug business and give up on rockets before it's too late and they go bankrupt

>>12804615
go talk to the /diy/ ham people

>>12804620
The moon is only suitable for a science outpost, to have a hope of colonizing it you need to stockpile so much material you're better off starting with Mars.

>>12804625
Nah they will take over the antares market of 2 launches a year by bidding a quarter of what the antares costs......

>>12804620
Totally, it's just a bit more difficult. Resource extraction requires more energy and infrastructure, but on the flip side, solar power is easier to get stupid amounts of energy from.

lol why is elon bothering with chemical rockets, retard should just go straight to warp, they made a couple articles about it on popular science

Could any of you anons spare an SN10 post-landing pop webm for a fellow American down on his luck?

>>12804654
...? why...

>>12804623
lasers are better then fusion overall but they require the most infrastructure

Io is a fucking chad moon it's covered in sulfur and has lakes of boiling lava

>>12804614
that's the only thing I'm disappointed with. I know it's easier but in the long run methalox would be superior for reusability. Probably propalox too

>>12804734
Kerolox engines might have a hard reuse limit.

>>12804738
Unlike some here I think "reusable middle lift rocket that learns from all of SpaceX's mistakes" is a great idea. But the keralox choice is more copying than doing that. I know that they have no experience with turbopumps, but a methalox gas generator should be within their reach.

Why?

>>12804768
Bro that’s literally just double standards for RocketLab. Ariane is doing the same thing. Both of them are retarded.

>>12804755
Put simple thin reflectors in orbit, I'm fairly certain you can get some kind of polished metal foil or thin panes to give you 90%+ of what's hitting them and beam it down onto receivers. Deal with 5-10% loss but you get power around the clock, the reflectors can't be obscured or interrupted so once they're up you can pretty much just leave them alone.

>>12804755

Later in the video he gets mad that Musk isn't talking enough about Perseverance on twitter. Why does he think Perseverance is so damn special? People already forgot about it because it's just Curiosity clone with some upgrades. Video from Mars was cool, but in the end it will get us nowhere.

>>12804823
>Later in the video he gets mad that Musk isn't talking enough about Perseverance on twitter.
Musk did not launch Perseverance nor was he involved in any phase of the mission. What do people expect him to say beyond "Nice job JPL, very cool!"

Lava ain't the only problem Io has deathly amounts of radiation. 36 sievert a day. That means about 4 hours on the surface and it's a coin flip whether you'll live or die. About 4 more and you are already dead. A whole day and you probably won't survive the next two. What the fuck would you mine anyway?

>>12804816
I'm not anti-nuclear but nukefags are so fucking tiring when they act like they're too based and redpilled to live on solar power. The solar panels, batteries, fuel cells, etc. exist. The equivalent nuclear infrastructure doesn't, the current choice is between too big and too inefficient (kilopower is a joke and worse than solar power in every way, fight me). We need miniaturized fast breeder reactors, but guess what, we don't have them right now.

>>12804839
solar power is just free-range fusion power

>>12804816
Sure, but the other anon's point was about solar power.
Realistically you would utilize both though.

>>12804723
>most of the video is high-school physics with bad approximations

>SN10 didn't land, Musk BTFO!

Fuck I'm angry now, is Boeing paying this smug asswipe?

>>12804839
Nuclear is neccesary on mars however solar farms should be used as well

>>12804830
Seems like it's okay.
I really hope we can get a Starship mission to either service it or bring it down as a museum piece.

>>12804849
What if somebody just beat him up in a parking lot? I don't know if that would solve anything but it would be cathartic.

>>12804818
To be fair, that's followers of anything

>>12804839
Solar accounts for less than 1.7% of the US power grid right now, Nuke accounts for nearly 20%. If we're talking about lack of power infrastructure, solar is nearly fucking nonexistent as a grid supplier. No, I don't fucking care that pretentious upper middleclassers use them to power their shitty houses, if we're talking about managing industrial size HVAC units and chemical air scrubbers, constant power management, and the charging of electrically powered vehicles like you're going to need for any colony in space, and you want to move a lot of power around a grid, Solar ain't exactly accounting very well for itself right now.
Now those problems can be solved, but lets not pretend for even a second that there's even a comparison between atomic and solar power for grid applications, there isn't, solar barely contributes enough to even be talked about in the large scale grid application argument at all.

>>12804868
Did you forget you're on /sfg/ or something? It's very clear I'm not talking about the (URF) grid. This is a technical stance, not a political one.

>>12804864
True, but it's the "le science" bullshit where people think some washed up chemist knows more about rocketry than the most innovative
aerospace engineers we've seen in a long time.
>>12804860
Musk should just spam Starlink satellites so the retard can't look through his toy telescope without getting blinded.

>>12804780
>>people aren't even mentioning it in the comments
pretty sure he deletes comments that point out the flaws, thus leaving only room temp IQ drones.

>>12804877
When did I say anything even remotely political? You said you're talking infrastructure, guess what, solar isn't even two percent of the infrastructure, if it were any less relevant to large scale power generation I wouldn't have even bothered to make a reply, and the further from the sun it gets the less relevant it will be as a power supplier.
Now if we're talking about a Mercury colony or an orbital around Venus, hell yeah solar is your power source, if we're talking about Mars and beyond, solar shouldn't be anything more than a supplementary power source at most, so far as it's proven itself here on Earth, .4 AU *closer* to the sun than Mars, it's OK at the small scale and pretty much irrelevant at the large scale.
How favorably do you think it's going to pan out from solar with 40% less sunlight, especially now that it's known that Mars' barely existent atmosphere is still doing a good bit of work to reduce that incoming radiation even more?

>>12804620
>large-scale manufacturing
is there any real incentive for companies to do this? will there ever be?

>>12804929
Megastructures

>>12804830
Reminder that the Shuttle left behind a docking port on Hubble. Realistically speaking, can a Dragon rendezvous and perform repairs? It has shitloads of unpressurised space in the trunk.

>>12804932
Dragon doesn't really have much in the airlock department.

I want to smell you, girl

>>12804951
Braaaaap

>>12804893
What's your plan for transporting a traditional nuclear installation to Mars, fucktard? US infrastructure does not have anything to do with space because it doesn't have nearly the same kind of mass restrictions. Even Starship isn't going to change that, it will change the magnitude of the problem but it won't make it make sense to use traditional nuclear infrastructure on other planets. It's barely worth it here because we're stuck on the uranium meme.
>How favorably do you think it's going to pan out from solar with 40% less sunlight, especially now that it's known that Mars' barely existent atmosphere is still doing a good bit of work to reduce that incoming radiation even more?
Considering that our starting point is Earth's atmosphere it's definitely doing that job less than Earth, as long as Miguel is doing his job and sweeping the panels. Second, with the volume and mass constraints, Starship can easily pack in >10MW of solar panels in one go even with the efficiency hit, they have low volume and high specific power. There isn't a nuclear system we can say the same about right now.

>>12804951
*smell you alive

>>12804961
The same way you'd send the many tons of solar panels, retard.

>>12804968

It's a huge company going for small and modular reactors. Much better than the bogged down bullshit most of the nuclear industry has been raped into. I agree that nuclear is futile until thorium reactors take over.

>>12804982

The science tube needs some rest okay

>>12804999
Integers confirm.

>>12804989
We need thorium reactors and once they're mature we need them on other planets, I'm pretty sure you could even do fuel ISRU on Mars. But until they're mature (and mature for space purposes which will mean further R&D) solar panels will be bridging the gap.

>>12805006

There was speculation that it was gonna be announced Friday which didn't happen, and making an announcement like that over the weekend would be odd. I'm thinking it'll happen this week, maybe tomorrow.

Constellation seemed like a great idea at the time. Launching crew and cargo separately? Genius! It’s just too bad that Ares I alone was like $14 Billion

Best timeline would be NASA realizing SLS is futile, but they would still be extremely happy to help commercial companies (coughspacex) get to Mars faster.
