With more dV being on the upper stage, isn’t mass fraction even more important than ever on Starship and even less important on Super Heavy? I’m surprised to see so much focus on SH weight reduction when it’s most important on Starship.
Elon Musk
@elonmusk · Jun 30, 2021
We’ve already done a lot of iteration on ship. For rapid reusability, booster must return to launchpad, so inert mass impacts ascent, boostback & landing burns. Triple whammy. Also, booster flight rate is ~5X that of ship, so multiple mass $ cost by 5.

Will the first orbital Super Heavy have grid fins?
Elon Musk
@elonmusk · Jun 30, 2021
First one to fly will, so Booster 4. Booster 3 will be used for ground tests. We’re changing much of design from 3 to 4. Booster 3 was very hard to build. Expect especially rapid evolution in first ~10 boosters & first ~30 ships.

This is one of the coolest shots of a Falcon 9 landing I’ve ever seen!!! I love how the engine violently reorients the stage on ignition and how they plan that into the landing trajectory. Such impressive engineering. B1060-8 just became B1060-9! 🙌

@elonmusk · Jun 30, 2021
Great shot! Btw, Starship Super Heavy will not have an entry burn. Delta-v is shifted more to the ship, so booster entry Q & heating is lower.

.@elonmusk is one of the greatest engineers of our generation.
He's doing amazing things, which seemed impossible to everyone a few years ago.
As a kid, he built model rockets, airplanes, explosives, tons of software/games. In college he built a basic MRI machine.

@elonmusk · Jun 30, 2021
Basic MRI is easier than it sounds good tbh. High resolution MRI in short time with weak magnetic field is hard.

I still can't believe it.
Starship has unused volume for people/payload.
Super Heavy is way bigger than Starship, and it's all fuel.

Elon provides a more realistic schedule for the Starship orbital attempt than the previous July target.
Michael Sheetz@thesheetztweetz· Jun 29, 2021Elon Musk: "We are going to do our best to do an orbital [Starship] launch attempt in the next few months." #MWC2021
Elon Musk
@elonmusk · Jun 29, 2021
There is the internal goal if things go right, which needs to be aggressive. Obviously, some things will not go right internally & there will be external issues too.
That said, I think we can stack an orbital ship on an orbital booster in July.

Unfortunately, launch is called off for today, as an aircraft entered the “keep out zone”, which is unreasonably gigantic.
There is simply no way that humanity can become a spacefaring civilization without major regulatory reform. The current regulatory system is broken.

IIHS has completed tests of the 2021 Tesla Model 3's new camera-based front crash prevention system, which rates superior for vehicle-to-vehicle interactions and advanced for pedestrian interactions. Details: go.iihs.org/2021Model3-FCP
Elon Musk
@elonmusk · Jun 29, 2021
Top Safety Pick+ from IIHS! That’s the highest overall rating, but we think we can get max score for all subcategories/individual tests too.
Retesting in a month or so with improved software. The improved software will then be uploaded to all cars with FSD computers.

Happy Birthday @elonmusk! Enjoy this catching system designed to help SpaceX bring Humanity to Mars!
Applicable for both Starship & Superheavy™, the light-weight system greatly increases margins for a successful catch. Full explanation here: youtu.be/fLjS8JqtnYM

Production release update coming this week, which includes raising max speed to 80 mph. Sorry, 75 mph limit was done as precautionary measure. Turned out to be unnecessary.

Special delivery to the #SpaceX Starbase/Boca Chica production site: a Raptor Vacuum engine! 🦖🔥 @NASASpaceflight
Three of these engines will be used to power the #Starship vehicle through space during orbital flights. Is this an engine for Ship 20 @elonmusk?
Elon Musk
@elonmusk · Jun 28, 2021
It is! Looks like we can get 378 sec Isp with this version of Raptor Vacuum, so over 380 sec with some improvements down the road.
