This foam (metal) armor would be great for micrometeorite protection for spacecraft. I think it would work great with the Starship since it is essentially the same type of metal. Also it may be a good compliment to the heat shield; the video mentions its insulating properties. … also mentions the foam armor’s radiation protection properties.

Molten material flows through a nosel where an extra pipe pumps in air and foam comes out (invented 1980s uk). If too much air is pumped in, it will turn into porus sponge material, (examine washing-up sponges)

Polysilicone can also be bubbled for extra insulation material.

In reentry testing foams soak up heat amazingly, but it is ablativley damaged and cannot be reused.

For the heat shield the foam metal could be designed to allow water or fuel to flow through giving it a role as a heat shield, micrometeorite shield and radiation shield.

TANK FABRICATOR/WELDER

Tank fabricators will work to build the primary airframe of the Starship and Super Heavy vehicles at the SpaceX South Texas build site. The tank fabricator will work with an elite team of other fabricators and technicians to rapidly build the tank (cylindrical structure), tank bulkheads, and other large associated structures for the flight article design of both vehicles.

I just read an article about double negative ceramic aerogels that might work to the same effect but be much lighter. But I just saw Roger beat me to it by 5 days…

The space shuttle had annoying ceramic foam block tiles, many needed to be replaced for surface scorching damage.

Any material that streches with heat might creak and crack. NASA tests space materials aboard ISS. MISSIE testing is at nasa glen cleveland ohio. They will have lightweight polysilicates space plastics.

Starhopper went for a little drive yesterday/today (depending on time zones)

Hmm, I wonder what the destination is? The dashed yellow lines are on the south side of the road at Boca Chica. If the sheriff is a rear escort, that means it’s heading west.

They’re definitely coming straight out of the launch complex. Those two trees are pretty distinctive.

Maybe they’ve gotten frustrated with it and are taking a quick trip down to Massey’s Gun Range to “install” some drainage.

Or… since the road does go to the airport, maybe they’re taking a trip to see the maintenance guys to learn how to properly do a tiedown.

Oh no! If they’re going to the airport they’re going to have to go through the Border Patrol checkpoint…

“Sir, I’m going to have to search your… uh… vehicle.”

Those powerlines could be a problem too.

Looks like they just moved it down the road to the launch site https://forum.nasaspaceflight.com/index.php?action=dlattach;topic=47120.0;attach=1548492;image

Maybe border patrol won’t be an issue

Video from the event. Starhopper was racing along! https://youtu.be/qIFpLblpC-E

Ah so they must have driven it east to the launch complex from the storage area where they had the radar dishes… just next to the housing area (which I would link to if google streetview’s pictures weren’t 9 years out of date).

Also means the sheriff was the lead car and turned around to watch things once it reached the destination.

Hmm, someone in the video comments suggesting that they’ve moved it here so it can safely blow up if it fails during pressurization tests. Sounds like good reasoning.

It looked to the quite the operation. There’s just a lot of speculation as to how they will be mounting the new fairing. I assume it will be transported to the LC using the same method.

And according to Mr Musk, Raptor/s should be mounted next week Elon Musk on Twitter: "Raptor on way to Hopper. Will be mounted to vehicle next week.… "

Getting exciting. Should be a fun year…

If the engines are coming that soon then I’d guess the timeline looks something like this:
Pressure tests this week,
Engine mounting next week,
Engine tests the week after that.

Looks like pressure testing, you can even see the skin wrinkle slightly as the pressure lets off:

The video author says: “The area will be closed for several days next week (March 25-28)”. Translation: fuel loading tests incoming.

We also had word from the man himself that what we see being built at Boca Chica is in fact the orbital prototype starship.
