SN3 [Two pictures] · March 26, 2020

Rafael Adamy@fael097 Replying to @elonmusk

A recent ArsTechnica article mentioned Starship will be 17 steel rings + nosecone. Is that correct? Independent measurements suggest it should have 20 rings.

Elon Musk@elonmusk

Pretty close. Design is evolving rapidly. Would be great to flatten domes, embed engines & add ~1.5 barrel sections of propellant for same total length. Also, current legs are a bit too small. 9:55 pm · Mar 17, 2020

Elon Musk@elonmusk

Some parts will use 304L, as it has higher toughness at cryo temps. Will move to internally developed alloys probably end of year. 6:18 PM · Mar 14, 2020

Elon Musk@elonmusk Replying to @flcnhvy and @JaneidyEve

We’re stripping SN2 to bare minimum to test the thrust puck to dome weld under pressure, first with water, then at cryo. Hopefully, ready to test in a few days. · 12:49 AM · Mar 2, 2020


Third Raptor test stand activated at SpaceX’s rocket development facility in McGregor, Texas. In the past year, the Raptor team has accumulated over 3,200 seconds of testing across 18 engines, including multiple full-power firings

SpaceX@SpaceX Last year, we completed a 150 meter hop with one Raptor engine, and the Starship team is gearing up for more spaceflight activities in Boca Chica, Texas · Feb 27, 2020

Testing Raptor in vertical configuration (on the giant tripod) should allow us to simplify some aspects of the engine design Elon Musk@elonmusk · Feb 27

Viv Dragon@flcnhvy

Will the fins still be actuated by electric motors & batteries? If yes, does utilizing Plaid powertrain & upcoming new Tesla battery tech that you’ve teased mean a significant improvement in efficiency & power?

Elon Musk@elonmusk Replying to @flcnhvy

Yes · Feb 25

Still 3 Raptors planned or other plans? · Feb 25,2020

SN2 tank integration starts this week with much less circumferential pucker. Thanks Fronius! · Feb 25,2020

Pranay Pathole@PPathole Replying to @elonmusk and @JohnHanzl

I wonder if having the O2 header tank in the tip is strategic to allow the boil-off to be consumed by the occupants? Conversely, keeping the CH4 header tank and associated piping away from the occupants is better for safety. · Feb 20,2020

Elon Musk@elonmusk

It’s mostly to balance the ship during entry. After delivering satellites, the front is light & back is heavy due to engines & landing legs. · Feb 20,2020

Elon Musk@elonmusk

High bay for stacking Starship engine bay, propellant tanks & fairing (fka nosecone) sections is almost done! · 2:29 AM · Feb 20, 2020


Will starship be moved to launch pad vertically? What is NASA doing with their old Shuttle and Saturn crawler carriers?

Elon Musk@elonmusk Replying to @sydney_ev

Attach wheels to the landing legs & tow Starship to the launch pad · Feb 20

Stephen Ross@pentaquarky Replying to @elonmusk and @Erdayastronaut < NEED LINK, could not re-find

How do you keep the oxygen in liquid form? Insulated header tank? · 9:57 PM · Feb 19, 2020·

Replying to @pentaquarky and @Erdayastronaut

The whole nose tip has to have heat shielding for atmospheric entry at Mach 25+ anyway, so is effectively already insulated well in orbit · Feb 19,2020
