NASA awarded the contract for the lunar lander, not the entire super-heavy Starship system (orbital rocket, orbital refueling system) previously unsuccessfully developed by SpaceX.So yes, it's SpaceX's fault for not developing this system until today.NASA was very stupid to choose such an uncertain concept requiring the development of completely new technologies.Fortunately, NASA later began talking about the need to award a contract for a second alternative lander in the event of a failure in the construction of Starship HLS. The commercial crew program is just proof of how delayed such programs can be because manned flights to the ISS were supposed to start in 2015 and started in 2020 Only that in 2015 SpaceX had a working rocket and a working cargo capsule on which to build the manned Dragon.Today, however, 3 years ahead of the planned date of the complex moon mission Starship HLS requiring multiple refueling in orbit, they can not even perform a suborbital demo flight of Starship

Hopefully there will be an Orbital Launch quite soon. SpaceX appear to be getting very close to that point, that I wondered if we would even see the first orbital class flight this year ?

Be careful to not give additional ammunition cause he didn't look at the rest of other space industries. Where's his complain about Starliner & SLS & New Glenn delays?

(SLS has longer delays than Starship, supposed to fly in late 2017 when announced (NASA date, not a political one))

probably wet dress rehearsal and maybe spin-up of newly installed engines. not likely a full static fire. even fast curing concrete isn't that fast.

edit: apparently FONDAG can be dry-mixed, so which would alleviate concerns with thermal cycling something with high moisture content.

FONDAG is usable at least 8 hours after casting

They mentioned that they won’t do 33 SP testing due to the “high energy event”

FireX would help prevent it, but I doubt they would risk a booster so close to launch

2 (non-explosive) 33 engine SP has occurred after Elon said that, so plans changed

Sounds like "next week" that u/Astronstellar is touting might come to fruition afterall

And for Astron as well: Why a maze of scaffoldings at S24 is preferable compared to more manlifts?

8 points · 3 hours ago · edited 2 hours ago

I would presume that scaffolding is preferred for welding and tile works as manlifts are wind speed restricted and also sway. Not great for precision welding, or possible contact damage to tiles. You can install more effective weather/wind breaks on scaffolding as well.

Btw, surely the solutions for avoiding damage on FireX is already been implemented, right?

Let's see:

  1. Offshore platforms is in back burner because the Stage Zero on land is difficult enough already. Absolutely zero work on both of them at the port right now

  2. There's ZERO evidence of a second tower on 39A (some are very recent like drainage) in planning documents

  3. There's ZERO evidence the SLC-40 crew tower will be the segment they're building at Roberts Rd. right now

  4. There's ZERO evidence of a second launchpad started construction & approved on Starbase (make zero sense cause why the heck it has to be constructed thousands of miles/kms away when they still have space at Sanchez site for exactly that?)

I expect most people here to be disappointed, despite the most obvious yet underrated option being right in front of them

I’m looking for the FAA doc. But here’s an article about pad upgrades to SLC40

We know that there'll be a crew tower at SLC-40, we have ZERO evidence that it'll be the tower segments constructed at Roberts Rd. right now

SLC-40 is explicitly mentioned as not an option for Starship in 39A environment assessment. It will be shocking if SLC-40 is remotely an option again before 2030s, Falcon 9 still needs it

That’s the crazy part! When you realize that this is the agency that put humans on STS-1, putting people on the maiden flight of a rocket with an escape system seems conservative.

IT SHOULDNT FEEL RIGHT TO PUT HUMANS ON A MAIDAN FLIGHT BECAUSE ITS INSANE!!!!!!!

But other people ("stans") are saying that launch escape system is 100% guarantee™ & a certain other SHLV (wink wink) are evil because it didn't have one so IDK

That was the original plan. Red Dragon was scheduled to launch in 2020, but was canceled when they switched development to Starship. While SpaceX could have touched Mars sooner, a dragon based mission would have been little more than a flag planting operation.

People often (maybe deliberately) missed this. SpaceX touted "self-sustaining" for a reason. If it's just for sending humans sake, their architecture would look radically different & much more similar to NASA & others

Wish Apollo has the same goal "we choose to go to the Moon.....and stay!" while taking advantage of high funding momentum, but ofc it has to sacrifice the "end of the decade" which was unacceptable (and this is why people shouldn't be mad on SpaceX delaying Mars landing by a couple of years. Prioritizing time only & you will sacrifice everything else)

Haha yeah. The fact that an engineer watching progress remotely via Twitter, could predict that there water tower was in danger of failing, isn't a great sign. They evidently cut some notable corners there. Makes me wonder if they went full cowboy while building the tank farm. Slap some duct tape on that leak and yell "yeehaw". But hey at least the oxygen and nitrogen tanks have been usable.

Could you expand on that? Like, not enough spacing between tanks?

Yes, vertical isn't what caused the problem
