They've passed some great milestones this week. Orbital table, tower, booster stacked, grid fins. That was a great week

[Usstampcollectersatkiwistamps]

Pretty much everything has been said here already but I'd just add that it's inspiring to see what this group of people has been capable of so far. Even when nothing else is going right in the world and there's negativity everywhere, I know I can always tune in to NSF and find something to be glad about and something to look forward to seeing the next day. So for all you contractors and SpaceX workers: Thank you for brightening my day. And, of course, I'm grateful to the NSF team for bringing it to my screen. Thanks.

I didn’t really appreciate how gigantic this rocket is going to be until right now

[DonnieB]

Whoever is managing all this and in charge of logistics needs a raise and a long vacation.

[alanc]

Excellent as always. Great job Mary, Robots and NSF Team. The level of dedication Mary shows each and every day is amazing and cannot be praised enough. To get the shots she does and the temperatures and conditions she deals with on a constant basis area true testament to her love of what she does.

Just imagine how good looking ship 20 will be once it is stacked and it has TPS tiles. I can’t stop imagining.

[Arae_]

YES! The orbital flight is near and I am unable to contain my excitement

[joyl]

I feel like I know my way around SpaceX Boca Chica better than my home town.
Been watching these video's since Starhopper flew. How quickly 2 years have passed and such amazing progress!

[learnerchris]

The QA effort to keep everything on track has got to be absolutely amazing!

[kyle.cushway]

And now engines going in as we speak. Absolute madness.

[MNTNMAN-SUCA]

Just wanted to say thank you so very much Mary/BOCACHICAGAL, for everything you do for us people's to be able to watch and learn from all of your AMAZING videos and hard work capturing them. You are the soul of the NASASpaceFlight Team and I know this because of some conversations I was privy too. So, once again Mary, from the bottom of my heart and surely from all the other MANY viewers, Thank You.

[rev.markcarrier]

Beautiful, clear video! Thanks Mary and NSF! Many of us watching since the beginning grew up with Mercury, Gemini, and Apollo. Then, for so many years, no human exploration. This is a dream come true.

[TeaBreak.]

We now need a CyberTruck permanently parked near the launch table to match the 3D models. 😁

[freefalltomars]

Seeing the launch table rolling down the highway and then seeing it up next to the tower really gives perspective to the enormity of it all.

[IntlDoesGaming]

Holy shit. It’s insane the size of everything involved in this from engines to ship and booster size, along with the buildings themselves. Seeing the scale of a raptor boost vs a vacuum engine is absolutely mind boggling. Not to mention the size of the launch tower and the massive crane involved in lifting all the pieces.

Just want to also say thank you to NSF for the insane coverage of Starbase. It’s truly unlike anything else. Great job to all of you!

[OortCloud]

Work at Starbase seems to be going quicker than it ever has before, This is really cool.

[eitansalama]

Crazy to think Marcus House's Video is now completely outdated after just 24 hours.

[dragnflei]

Mary, thank you so much for all these fantastic videos. Your sunrise segments are epic! Thanks to the whole NSF crew, too, for scrambling to keep up with all of the action.

Can’t wait to see Starship mounted on top of Booster 4.. it’s gonna be glorious!

Then, when it launches for the orbital test.. history will be made.
