Now all they need to do is attach a pressurized air hose and pop out all those dents.

Were any *innards* ever observed being installed? You know, tanks and lines and pumps and and all the rest?

And so the endless circle of life comes to an end, meaningless and grim. Why did they live, and why did they die? No reason. Two hundred million years of evolution snuffed out, for in the end Nature is horrific and teaches us nothing

On NSF they have some close-ups of what looks like a tank bulkhead weld as seen on the outside.

Range?  These things are coming down a couple hundred miles out to sea.

Replace the giant net with a helicopter landing pad.

Meh. You're adding systems. A ship *should* be able to catch the fairings, especially with guided parafoils. It'll just take practice. And if you can do it with ships, then choppers are extraneous.

Looking at that again I wonder if just making the parachute a bit bigger to slow it's decent would help.

As Moose mentioned; it looks like they're going with a steel, full-diameter tank for the 'Starhopper' [see attached pic].

Were any *innards* ever observed being installed? You know, tanks and lines and pumps and and all the rest?

Unknown, they built the thing with a concrete shell around the base, so we didn't even see the nozzles (regardless of whether they're attached to any engines) get inserted before it was raised and placed elsewhere.

According to Elon however:

Engines currently on Starship hopper are a blend of Raptor development & operational parts. First hopper engine to be fired is almost finished assembly in California. Probably fires next month.

It's not clear whether those developmental / operational parts are basically just the nozzles + gimbal mounts or something, or if there's whole engines in there, but they plan for the Starhopper to make its first hop in 3-7 weeks:

Adrian @LPAmdee
How long until the first hopper test. What do you think?

Elon Musk @elonmusk
Replying to @LPAmdee
Aiming for 4 weeks, which probably means 8 weeks, due to unforeseen issues

Kinda counter -intuitive, but possibly need the opposite.
Bigger actually makes you more susceptible to wind drift.  But it'd definitely work if they never launch when it's windy out at sea downrange :)

Hopper is now complete. Orbital test vehicle will be complete by June. Speed of development is amazing compared to something like SLS for example.


Follow this Twitter thread by EM. Picture of complete hopper on first post.

Or make the 'chute steerable.

So I was able to get a bunch of clear shots of the raptors and the “bulkhead,” there is also an envoy of cement trucks and I counted 12 already on the launch pad tilling the cement in the back of the trucks waiting until their gonna start poring i have to guess.

The nice border patrol agents at the check point that I just became friends with 😂❤️have just informed me that this upcoming Monday is when their going to take apart the hopper and insert the fuel tanks.

Fallout from the mess at Telsa, et al., I suspect.

Unlikely, funding of both companies is separated, SpaceX is also a private company, etc. The more likely explanation is that they've had a lot of concurrent R&D projects happening these past couple of years (Falcon 9 Block 5, Falcon Heavy, Dragon 2, the fairing recovery system, BFR, etc) and so they've had to expand, but now Falcon 9 development is pretty much over, Dragon 2 is on the verge of completion and now the focus is just on BFR (Starship + Super Heavy). A 10% workforce cut is small enough to match the closure of those other R&D projects.
