SpaceX Boca Chica: New 3mm Test Tank SN7.2 Tested for the First Time

25% thinner than previous Starship tanks, SN7.2 was tested to prove new manufacturing techniques to build lighter tank sections. At the production site, it's a hazy day as crews stack another ring atop Super Heavy.

These images are just beautiful. Now the lovely surreal mist! Thank you for continuing to document what's being done here in such a stylish way.

[Kayuryuk]

And course big thank you to mary for the amazing shots on a daily basis

[debbieatkinson]

I love watching these videos you make Mary. It’s such a busy place. There is always something going on! Trucks, cranes, equipment, people. Busy busy!

[davidallyn]

Mary, bravo on your production quality!! I love how you add your environmentals back in after speeding up the footage, and I can hear that you add extra bits and pieces here and there to heighten the experience. Not to mention your footage is clear, crisp and captures just what needs to be captured in the moment. Captions are concise, and you tell a complete story throughout. Thank you for your hard work!!

[stephenv.russell]

I look forward to these videos daily. Great job Mary

[nealraudabaugh]

Caught this one real early. Keep them coming Mary!

[cosmo]

Thank you so much for your dedication and generosity. Love watching these so much

[seanevans]

Can't wait for SN9 to fly, awesome work you guys!

[TwistedQuestionMark]

Thank you, Mary! You're a gift to space nerds🙏

[devindykstra]

I'm kind of glad SN9 is delayed. I really want it to fly, but I also want to be able to see it. This fog is horrible for that.

[donbeverly]

Well done as always Mary, thanks again @bocachicagal

It must be weird to work at a company where everybody walks like they're in a silent movie.

[joseph-thewatcher]

So many moving parts. Amazing how far along things have come in such a short time.

[lspringerjones]

This is the most futuristic looking video you have done. The monochrome sky makes it! Kudo!

[clarkkent]

Elon has tweeted that SN7.2 passed pressure testing.

[matthewerwin]

7:40 RT OK 9/15. That weld passed x-ray on September 15th. FYI

Let's hope they pull this off, it would be huge savings in terms of weight
