The thread is about what not to put in KSP 2, so he's right

Not exactly. These are all things that are planned a long time before they are needed. They don't look in the storage and say "NASA, we're out of coffee, send us some more if you want your science", everything is calculated precisely to fit the needs and has launches on schedule half a year before the actual date. This won't change for Mars, everything will be calculated and sent to be able to arrive with enough margin. This is more definitely problematic on Mars, agreed. If something catastrophic happens to the base, you need to survive there for a period between a few months+6 months for travel time and 2 years if mars and earth are on the wrong side of their orbits, although I'm positive that if the payload isn't that big you could go there even in non-perfect launch windows. If you can't do that you have to abort and go back to orbit to start the trip back to Earth, provided the earth return rocket is still working. But if both the ISS and the return capsules broke you'd be screwed as well, so the very last part doesn't change. This would be identical for Mars settlements, just that the return would take 6 months instead of a few hours or a day at most.

According to the usual insiders on reddit, static fire is currently targeting tomorrow

Check yo staging SpaceX, you already forgot to put the parachutes on Starship

RC 57, 59 and 62 installed on Booster 3

That's not how it works. Don't take Angry Anstronaut's word as gospel, they are absolutely meaningless given that he made absolutely zero calculations in the video. The comparison you make there is meaningless. It takes 2 minutes from 10 km on earth to sea level with the drag created by starship; without any atmosphere and earth gravity, the same process would have taken sqrt(10,000/9.8)=32 seconds. But there's no place on mars where the atmospherical density of mars is equal to the one at earth sea level, or even at 10 kms of height for that matters, so the two cannot be compared. The second part of this that is uncomparable is the flight profile. On any starship hop, it is vertically up and down. On mars, it is the exact opposite, that is almost horizontal. There is no horizontal terminal velocity, only vertical, which means the atmosphere is going to bring you as close to zero as possible horizontally. Third, you talk about free fall. This is not free fall, at all. Going at terminal velocity always means that you *aren't* in free fall, in fact the vomit comet to simulate free fall has to use its engines to compensate for the atmospheric drag. Again, never take a youtube video as a source. Make your own calculations about what is being talked about, or better yet find a reliable source talking about the problem to see if it actually exists. This one in particular literally cannot exist, the drag created by a particular shape can be throughly verified in computer simulations and doesn't need real testing nowaydays. They were testing the control from the aero surfaces, engine reliability, cold gas thrusters, pressure holding of the tanks etc, but nothing like that. it is clear in the video that Angry Astronaut completely misunderstood the nature of the test

As I said, completely unreliable source. Check the comments of the video you linked, even them make fun of this Only to quote a few:

Angry astronaut has been proved to be one of the least reliable source on Starship and spacex in general, on par with Thunderfoot, getting way too many things wrong to get the "it could be just a mistake" pass. If you link that as your source you may as well link a 4chan forum. If you can find any reliable source on that I'm all ears

What? In what way did they prove that exactly?

It's clear that is a test article, the nose nor the barrel is marked for SN20 and those sections for it have alrady been spotted. Not to mention, no flaps attachments. I'm not 100% sure that one on the right is the one for SN20, but it's definitely possible

This is thread at this point is basically no different from:

Now that's a name I haven't heard in a long time Also, Booster 3 now has three Raptors installed!

I am not passionate about him, in fact I couldn't care less about musk. But spacex isn't musk. There is of course nothing wrong with not following someone or something, it's very normal. But if you don't know something simply say that, don't make stuff up: There are no hordes with pitch forks going against you, you simply said something incorrect and people are correcting you. It's how life works, nothing wrong with that. As for spacex, since you were wondering what people like about them: They are the only company capable of sending up astronauts from the US, which hasn't been possible since 2011. (The only other vehicle for these 10 years was the russian soyuz) They are the only company landing rockets and reusing them, instead of throwing them in the ocean (or on land, see china) They already have the most powerful available rocket, the Falcon Heavy They are building the most powerful rocket in history as I mentioned before, the first rocket fully reusable and that has a lot of uses planned for it (human lunar lander, human mars lander, super heavy unmanned launcher, point to point transportation. Obviously not all will materialise, but these are the planned ones) They are extremely open about their development and current status of things, you can see about everything they are building re starship in the open in Texas which is unlike almost any space company Lots and lots of extremely cool videos (not renders) on youtube and the like

No, they haven't . SpaceX is building the lander to go back to the moon in 2024 in the artemis program, the 50 meters high starship with a 100 tons payload that has already done multiple 10 km atmospheric hops testing the system and will do the first orbital flight in august/september on the biggest rocket ever. Does that answer your question?

Yes, that's what I said. First time in 2020, and by now three times for 12 people total

I'm sorry, but you seriously seem to have come straigh out of 2014. Falcon 9s have been landing orbital class boosters since 2015. Since then, there have been 89 successful landings of a falcon 9 and (after the first successful droneship landing) 4 failures. Falcon 9s have also been launching people to the ISS, which is in space, since may 2020. Three capsules with 4 people each have since been launched, one of which is docked to the ISS right now (Crew Dragon Endeavour) and are the only crew rated vehicle the US has. So no, it is not accurate enough. In fact, it is completely wrong.

He isn't SpaceX is doing exactly zero SSTO, please get at least a single fact right if you want to call everyone a fanboy

Who knows, maybe 70 km is space on kerbin because it's a round number there too

Uninterrupted video of yesterday's flight

Make a new system, where 83.6 km is a nice round number

Not exactly. The line Von Kàrmàn calculated as the boundary where atmospheric flight is no longer possible at velocities slower than orbital speed, with the X-2 data, is 83.6 km. The FAI Kàrmàn line, 100 km, has absolutely no meaning other than "that's a nice number"

It's likely that won't be a flight hardware, just a pathfinder. It doesn't have flap mounting points. Isn't the nosecone on the right, the one spotted some days ago with the heat tiles, the S20 one?

The 2050s are 30 years away, not 20

Wrong HLS system, they would need to ask to Dynetics for that

Worth mentioning that this was an actual proposal at one point:
