Super Heavy Booster 4 Lifted Back onto the Orbital Launch Mount | SpaceX Boca Chica

Super Heavy Booster 4 was lifted onto the Orbital Launch Mount for a second time, potentially for fit checks. Meanwhile, work on Ship 20's Thermal Protection System Tiles, the foundation for the new High Bay, and the Chopstick arms continued.

Wow that's a lot of engines. Can't wait to see them all firing at once

[stevenf]

In my mind I imagine Tory Bruno looking at those 29 Raptors. "Where are my engines, Jeff?!?"

[LimeJuice]

Not long before we see that beautiful full stack again
I’m so excited:D

[ReadTheShrill]

Wow. The scene starting at 5:16 really gives you a sense of just how huge that booster is. Great shots, Nic Ansuini.

[danielowens]

Love your work, keep it up!!! I was just out there last weekend, the place is amazing!!!

[engineer]

Often imitated but never duplicated! Keep up the good work NSF team!

[-A-c]

Oh man, for a few seconds during launch it’s likely gonna look like a massive purple lightsaber is being pulled out the ground….. I may just faint.

[twistedpixie]

I can’t wait to hear the Raptors fire all at once. I’m in Ohio and I was joking with my husband the we will probably hear them here.

[Tiki]

8:30 Dude is swinging in a basket and welding. That's gotta be supremely difficult. On a tank that MUST hold pressure. Wow.

[badrinair]

Thank you Stephen, Nic, Mary and the NSF team for bringoing this amazing footage to us. it will be quite hectic and thrilling ot work on a project like this.

[ryanschupbach]

8:53 that guy was walking with purpose wasn't he?
Finally made it down from Illinois to see what all the commotion was about. Totally worth it! Noticed those triangular/wedge shaped things on the OLP when I went by and in the video. Any idea what their purpose is?

[benjamint]

The chopstick system will be awesome when it will be completed. I hope when it will be ready and installed, they will test first by lifting SN16, so he will have served at lease for something ^^
And if the system failled and Starship fall, it would be less expensive than a brand new Starship

3:10 looks like grease lines for lubing all the pivot points/pins from one central location.

[aximov]

It’s still super interesting to see (mostly) all the framework and piping of the raptors extruding from the base of super heavy…

[pyrofan]

That’s an entire Jurassic Park of raptors right there

[mrengtop]

It's unbelievable how all this hard work will be translated to a sustainable colony on Mars...👌

[seank]

Thanks, Steven, Nic and Nate. I enjoy the beautiful sunrise shots.

[poisonketchup]

i cant wait until we will have cameras on mars and bocachicagal will be recording the construction of the first martian

[catbertz]

Woohoo get to watch before my bedtime!
