The way things are going it feels more likely that it's going to do a Challenger instead of doing an Apollo 8 :/

What is fun about stuff like this is that it shows something we could theoretically build today if given enough motivation.

Everyone thinks we need to invent something superfast to get around the solar system, but the reality is larger vessels that spend months to years going to various destinations are more feasible.

Lunar Orbit would also be the best place to launch such vessels from just due to the massive force difference between orbital escape velocity from the Moon vs. the Earth. It would allow a vessel to build up a greater amount of speed from boosters before getting hurled out too wherever. The fact that the moon has no atmosphere also means that the orbital escape burn can happen much closer to the surface. Which is huge because the angular momentum principle will allow the vessel to build up greater speed before escaping.

Also this is really dumb. The chances of challenger being recreated with Artemis are really dumb, and is much more people wanting to attack Artemis - Which has been really common for years (the program isn't really doing itself any favours. It has been pretty badly run, and underfunded as there are a lot of additional costs from the low cadence such as being the only renter for NASA facilities like the VAB and elsewhere. Which is where a lot of the budget goes). The only way that it ends up like a Challenger is if 1: The weather conditions are too bad that the O-Rings fail (not necessarily guaranteed to result in mission failure, as SRBs can be quite sturdy. The O-Rings failed immediately with Challenger but 2: The winds are at high altitude meaning that if the SRBs manage to plug the whole (remember they are solids) booster failure doesn't always result in a challenger/Delta 2 disaster. Rather, there have been multiple cases of SRBs managing to get into orbit even when failing. Case in point, the last 2 Vulcan launches. Nozzles failed, still got to orbit.

Now, SRBs aren't optimal. But for something like SLS which uses a high energy trajectory you kind of have to use them. It's what SRBs are good for.

Oh and 3, Orion can perform an abort, the shuttle couldn't. Either abort to orbit, launch count abort, or one using the launch escape system. Challenger happened because of a shit ton of variables lining up that would never, ever happen again. Well, it could happen *possibly* if SpaceX puts SRBs on the side of Superheavy. But Superheavy is so LEO optimized that there's little reason why anyone would. - You just don't need high energy trajectories.

Again, all of this is that people just really like to attack Artemis. I've seen people try to defend Constellation instead of Artemis because it would have been so much cheaper to use Ares 1. Which is a big, no.

You understand this is an analogy, not a literal comparison, yes? Saying it'll do a challenger means it'll explode due to NASA ignoring fundamental engineering problems,and set back the space program as a result, not that it will literally repeat the circumstances of the challenger disaster line for line.

I didn't say it was going to blow up because muh O-rings, I said I'm worried that it is going to blow up. The entire timeline has been rushed as fuck and they keep finding oopsy woopsy fucky wuckys because of their very probably overengineered "bespoke" components. I don't want the fucking thing to turn into a fireball for any reason, I want it to work

Gentlemen, Gentlemen please relax. Autists have a hard time understanding analogies and non-literal speech. This thread is both on the Kiwi Farms and about space and rocketry. Higher quotients of said Autism must be expected and accounted for.

All that said, the Artemis II design and plans are extremely conservative, and arguably obsolete from the start. I don't worry about it blowing up. I worry about the constant delays for a rocket platform which has very little future.
 
Fuck, stop talking about the damn ship blowing up it's making me nervous. In the words of Gene Kranz during Apollo 13, failure is not an option. If Artemis II blows up, that's it for NASA, they can't accept casualties and setbacks anymore like they used to. God damn I hope it works, almost as much as the crew going up in it do.

Indeed. The stagnation has been terrible, all I can hope for is success that may revitalize the space race. It's so frustrating knowing how many things died after 1972, fuck sake bring back NERVA and get those nuclear rockets going again. I don't give a fuck that they need enriched uranium, buy it from the Iranians for all I care, just bring back the good ol days of nothing being impossible and US flags being planted on other celestial bodies.

This is where I continue to sperg in this very autistic thread about the future of space flight being made on the moon rather then on earth. Because the moon is a literal gift from the heavens when it comes too the situation intra solar travel.

Seriously. If a creator god intended for us to escape our planet, Luna exists according to his design. At a stable orbit outside the home planets gravity well. Low relative gravity, but enough to form a stable orbit. No atmosphere allowing for orbital sling shots close to the surface. Frozen water deposits. Hydrogen 3 deposits. All the core metals required for manufacturing spacecraft. Including Iron and Uranium of all elements. Which are catastrophically rare all things considered in the grand scale of the cosmos.

It is said God created beer because he loved man. The Moon IMO is a greater indication of divine destiny. Its a literal cheat buff to inter planetary travel that does not exist anywhere else that we have observed.

Falcon 9 in fueling stage and reacting. They are go for launch.

This is the 33rd flight for this rockets Merlin booster. This will be an orbital mission, with a booster landing burn.

Nice flight, nice landing. Falcon 9 is a fucking beast.

SpaceX has been on a roll lately. Also, they are about to clown NASA. With Artemis still stuck on the launch pad, SpaceX is prepping for Flight 12 of their Starship launch stack. This is the companies own lunar mission program.

This will be the Version 3 iteration of Starship,. Its slightly larger then the V2s tested last year and is the one proposed for interplanetary manned missions. Basically this one comes with a refueling stage. Once in Orbit, a second starship can be sent up carrying a fuel payload that will refuel the first Starship.

They are aiming for a March launch time.


NASA also released a report on the Starliner Debacle from last year. Helium leaks and an unprofessional conduct galore.

NASA going to hold a presser about the wet dress rehearsal of Artemis II today at 11 AM.

They had better say we are good to go for the launch window dammit.


*Edit*
Artemis II is approved for launch!

Launch window opens March 6

And now the launch has been bumped into April because of a "helium flow" problem

Fuck you NASA turn it all over to Elon already I guess
