Also, they're hooking the cryo shell right now

-
Presumed to be a GSE test tank made of the top and bottom of GSE 4
-
The LR 11000 has returned to the orbital launch pad and been attached to the cryo tank load spreader, which indicates soon they will lift one of those to cover GSE-6, see this diagram: GSE-1 and 2 are still being worked on to solve the problems that led to GSE-4 being scrapped, so that's the only one

It's a nosecone for a future starship as far as we know, perhaps S24/25. Musk showed already a smoother nosecone being built in the tents as their manufacturing process improves, this is that one or maybe even smoother
-
I have no idea why, but it looks so fake like that
-
And even if you manage to get a contract for ambitious stuff, that doesn't keep it from getting cancelled a meter short of the target, see X-33

My personal theory is that November 1st was the first possible date NASA thought this could be solved: the 300 millions SpaceX received from NASA recently are known to be the maximum milestone payment they could receive in FY 2021 so for a while the protest wouldn't matter; FY 2022 would begin in October 1st, but perhaps they believed that the case couldn't be settled by that date so they postponed it by exactly 1 month. If everything goes according to the plan the process is delayed by that month and after that HLS can continue without further problems, meaning instead of an unlikely but still possible delay lasting an undefined amount of time (injunction) and a lengthy legal protest there is next to no effect on neither SpaceX nor NASA (in the case of BO losing)

We don't really know that, EDA came in contact with Musk first during a press conference and would have been a youtuber with or without SpaceX. At this point, we would be going basically to the point of "if SpaceX was much more secretive in general it would be almost as secretive as BO". The only thing that we know wouldn't happen without the cameras everywhere is what comes directly from having those, i.e. Brendan's diagrams, Mary's pics and 3dcentric's OLT construction videos, everything else is For All Mankind level speculation. Not that I'm opposed to a for all mankind with the starting point of spacex not allowing cameras on pointed to their stuff, I just think it wouldn't have too much public
-
I am actually 50% sure that some insider proposed that name because internally SpaceX was calling it like that, but don't quote me on it. Every name is fine until we have an official word on it

S20 testing dates have also been published, 24th August being the primary with the 25th and 26th as backup https://www.cameroncounty.us/spacex/ Last, the Giga Bay concrete prep began, with the first steel erections set to begin 1st september
-
I disagree. If we didn't have people that can take those pics directly, we would still have: - the 3 parts of the Everydayastronaut interview, composing over 2 hours and a half of Starship info (which would have told us basically every single piece of info we know of starship except the current amount of parts spotted) - the various launchpad cams, which are placed in SpaceX land with their authorization - the occasional informations from Musk on Twitter, which would be enough for a lot of speculation over r/spacex It's far from the level of info we have now, but it's also very far from the level of info BO publishes. Enough to make SpaceX look still a bitless secretive than the average space company

Seriously??? If boeing said "This test flight only tests reaching orbit, later we will do 15 more test flights and then put crew on it" OFT 1 would have been a success. There is an enormous difference between "this is the last test, then we will put people on it and fly to the ISS!" and "who cares if it fails, we need to free the launchpad for the next one waiting in the high bay". Boeing didn't want to do more tests, nor was ready to do more tests, nor could do more tests without mayor critics on how late they were. Starship was literally a water tank with a raptor that instead of oxygen rich or methane rich was engine rich until a year ago. This is the first test of many, nobody will say "from today, starship is an operational NASA vehicle". Seriously, that was possibly the least meaningful comparison I could think of. You can think what you want of SpaceX, but comparisons like this are absurd

What do you think about Jeff Bezos suing NASA?

That's the intention -
Netflix Inspiration 4 documentary trailer is out, part 1 and 2 will come out 6 september If we ignore the Ariane 5 and Saturn V separation footage it doesn't seem bad. Hopefully whoever chose those shots for the trailer wasn't involved in anything else
-
Hmmm, I bet on reentry. We wouldn't see it do a bellyflop and land in the sea, but at least we will have pics of S20 in orbit
-
To quote musk, "If it clears the tower it's a success". Flight will be full of unknowns, even if we as armchair scientists do believe completing the ascent profile will be likely But as magnemoe said, S20 surviving reentry is between very unlikely and impossible. Musk said many times that they expect to blow up a lot of them before reentry is successful

https://fcc.report/IBFS/SAT-AMD-20210818-00105 SpaceX changes with the FCC the future starship launches, V2.0 will be done with starship starting next year and V1.5 will be done with Falcon 9 later in 2021
-
It's not exactly an error in S20 to be like that, SN15 and previous proved that it can work; it is just an improvement that we will see in future iterations, perhaps not even in S21. Once it is implemented it should probably reduce the amount of heat shield tiles required and make the flaps more effective, but there's nothing keeping S20 from flying given how much stuff needs to be verified even before the flaps start making any difference

https://boards.greenhouse.io/spacex/jobs/5477244002?gh_jid=5477244002 SpaceX is looking to hire an Offshore Operations Supervisor in Brownsville to help "convert our vessels Phobos and Deimos into Starship launch, landing, and propellant generation sites" Chances are initially the propellant production will be limited to LOX (it's almost 80% of the fuel after all) and that perhaps Phobos is set to move to Brownsville after it is emptied? We'll see Also: They are chaining them down, so likely leaving in direction MacGregor

Also, it all only concerns the nosecone (lots of custom tiles, was always known to be hard to tile) and the upper section of the upper tank (tiled in a single day down at the launch tower waiting for the test stack). The rest of it, which was done in the tents and high bay, is full of "ok" written on it
