Overnight, crews stack a new ring section onto Super Heavy BN3. Meanwhile, Frankencrane prepares to stack the new Launch Tower section.

  2. Why is SpaceX building a land based launch tower when they plan on eventually conducting all operations from the ocean based platforms?

  3. At 1:57 NSF is claiming Nitrogen as an insulator for cryogenic tanks. The air we are breathing is 78% Nitrogen, why should 100% Nitrogen miraculously become an insulator ? Have you guys ever had a physic book in your hand, ever heard the term convection ? In contact with the warm shell the Nitrogen would boil off, ascending, and at the cryo-tank it would cool down and be descending: a perfect circular flow for heat energy transportation. Nitrogen is the opposite of an insulator so please stop spreading such rediculous fakenews !

  4. Feels like now that the foundations are mostly in place we are going to see the infrastructure build just explode in growth! (Wrong word – explode). Great camera work Mary and team! Thank you

  5. I did not realize the precision here (6 + min) where they actually adjusted the turn buckle plates to adjust for which straps go on the bottom and top in the hook…. Now that is precision there!

  6. 13:00 looks like dividers for engine chill purposes to me. On the wider section of the barrels are 8 exits on each barrel…. = 32 (29 for the booster raptors, 3 for the vacuum raptors in Starship)
    the two connectors on the smaller end may interconnect those barrels and support coolant (LOX? Liquid nitrogen?)

  7. Is it just me, or does FrankenCrane not look tall enough to stack 140 metres worth of tower.. looking at the sections of boom (each the length of a semi-trailer – 10 metres or so) it looks to have a reach of only about 70 metres..
    Will they extend it as the tower gets higher..?

  8. I’m starting to wonder if SN really stands for “serial number”, not “starship number”. Once again, we have missing numbers— no SN18 or SN19, jumping from SN17 to SN20. Meanwhile, we have 2 Super Heavy boosters— BN2 & BN3. Perhaps BN2 is also named SerialNumber18 and BN3 is also SN19? And BN1 was one of the missing SN12-SN14 serial numbers?

  9. Good morning/afternoon or evening wherever you may be! Hope this video makes you excited for the future as much or more than it does for me ? thank you Mary & the NSF team! ?

  10. To be able to remember back here in 5 years whilst watching two booster launches simultaneously and recall how we watched the site being fast track constructed.

  11. 15:30 – Just some valves and piping at the launch site. But I am sure that there are 3rd party workers who made those support pieces at another location, that are watching these videos to see if they can spot their welded stuff.

  12. I've been watching this for a long time now, and it's only just dawned on me that I'm basically watching the next Kennedy Space Centre being built. A-freaking-MAZING!

  13. I hate to be a curmudgeon, but this year's Atlantic hurricane season starts in about a week. This marvelous Starbase is being built right on a barrier reef just south of Brownsville Texas, which has seen a hurricane catastrophe or two in the last century. I understand that the cranes can be tied to the ground and the buildings are likely built for high winds. However, what about flooding from storm surge? Starbases are generally not compatible with a several day soaking in salt water.
