What's the touchdown speed for the Dragon Capsule? If it's low enough, perhaps you could just land on the recovery ship's helipad..

If I had a dime for every time some corporation CEO promised they were working on fixing something that never ended up getting fixed, I would already be retired and driving around in my Ferrari.
Heh, true. I'm a bit more optimistic though. If that does happen, then I'll be happy to lambaste SpaceX with everyone else.

StarLink is already wrecking Astronomy. I fear nothing will be done about it.
If I recall correctly, all the issues with astronomy and the Starlink satellites have occurred while the offended satellites were still raising their orbits, right? Regardless, the article seems to be complaining about problems that SpaceX has said they're working on fixing, but then it whines that they haven't been able to instantly implement those fixes. One of it's proposed solutions is literally something Elon Musk has said they're trying to do (reduce reflectivity). The concerns are valid, but it sort of completely ignores that SpaceX has had their head honcho directly respond to those concerns and offer some solutions they're working on.

Turn that dome upside down, fill it with milk, and it will have been a flying saucer.
I'll see myself out.

Looks like the top bulkhead was completely blown away...
Camera 3 from the livestream has a nice view of it being blown off and falling back down.

You jinxed it.
Nooooooooooooooooooo!

And not actually nessesary for lunar launch. The core stage should have plenty of TWR on the lunar surface, it doesn't need boosters.
Ah, but we're primarily concerned about the coolness factor, for which the SRBs are essential.

RC Dozers doing a little moonscaping project in preparation for Artemis landing? Maybe even paint a giant X in the center?
Maybe build a nice long-term habitat housing 100 as a welcoming gift.

If you brought the solid fuel (IDK how many launches that would take) and then made the hydrolox from ice they may be able to launch it from the moon assuming they built a launch pad.
Solid fuel alone is apparently 11 of the 25 launches. That stuff is heavy.
-
My back of the napkin math says that assuming SpaceX reaches its 100 ton to lunar surface goal, and ignoring volume constraints, it could take an entire fully fueled SLS to the surface of the Moon in ~25 launches. If you dump the fuel, it only takes ~3 launches. Who knows, that might actually be cheaper than making SLS fly.

Or instead of an accidental button push, someone knows how closely we watch for that sort of thing, and decided to have a bit of fun.

Air force spends 500 billion trying to turn Starship into a stealth rocket.
"Our project has not found a way to prevent detection of a large object reentering the atmosphere, but instead of writing off the whole thing, here's a way to send hundreds of 500 million dollar dummy Starships into the same area so that the enemy doesn't know which is the real one."

If there are no other major failures, losing pressure during reentry is likely survivable as all crew and passengers will at least have sufficient gear to provide breathing gas down to landing. The failure of Soyuz 11 saw to that.
That was a valve failure, I'm thinking more along the lines of a hole in your fuselage.

Personally, I think starship needs to be able to survive a malfunctioning winglet.
That's a fair enough criticism, but airline levels of safety in any vehicle that has to go through re-entry is not something I think is possible in the foreseeable future. The nature of re-entry is not very gentle. If you lose pressure in an aircraft, the oxygen masks drop and the pilot dips down to safer altitudes. You lose pressure in a re-entry vehicle, your passengers are dead, and you're lucky if the ship lands in less than 10,000 pieces.

Aircraft are actually flown enough that each has a real history. I think any attempts at that sort of reliability will take a great deal of actual flying.
And possibly some impressive leaps in aerospace technology.

It needs airliner-like safety. is it a good idea to give it so much instability?
I think the airline comparison breaks down more often than we'd like. Space travel is inherently more dangerous than air travel, and vehicles meant for the space environment may need to break a few rules that airlines hold to.

Good to hear I'm not the only one who loves that Wanderers video.

I'd like to see a NASA-SpaceX partnership happen if we get closer to actually being able to go to Mars. SpaceX might be able to run an entire Mars mission by themselves, but I'd like it if they had some folks with more experience at the whole "keep humans alive for more than a few days" working on the habitat and life support systems you'll need for a colony, or even just a base for waiting for a transfer window.

This thread is nuts.
Well, we can agree on that, although maybe not so much on the reasons.
-
I think it more likely that NASA does understand the value of destructive testing, but also realizes that blowing up multimillion dollar spacecraft doesn't look good to Congress and your average taxpayer.
-
And don't forget all the test engines blown to smithereens in the pursuit of a decent propellant that won't kill you if you look at it too long.

Granny can't make a splash screen, and she doesn't get analytics. She will still be harnessing the exact capability of what KSP2 has available. https://store.unity.com/compare-plans
She doesn't get source code access either, which is not an insignificant detail.
-
I will point out that grandma's free copy of Unity has very different capabilities from the paid, developer grade version of Unity.

Although a WALL-E situation would lead to the fascinating if strange combination of rocketry and snowplow technology.

I was able to watch the orbital insertion from my backyard in North Carolina, it was the coolest thing ever. A tiny orange dot with a plume of light grey-orange streaming away from it, traveling across the sky.
