Exactly! Merlin for example can deep throttle down to under 40% of its max output (I forget the exact number) thanks largely in part to its pintle injector. Raptor hasn’t gone below 50% that I’m aware of and might have a harder time doing so than the Merlin.

Max demonstrated Raptor thrust is ~225 tons & min is ~90 tons, so they’re actually quite similar. Both Merlin & Raptor could throttle way lower with added design complexity. Raptor preburner & Merlin gas generator flameout are what limit lower bound.

To be fair, none of those other companies implemented fart mode. mashable.com/review/tesla-m…

How many Raptors for SN40?
Elon Musk
@elonmusk · Aug 17, 2020
That’s engine SN. We’re building SN8 of the ship.

Nice! What SN are you up to now?
Elon Musk
@elonmusk · Aug 17, 2020
SN40 is about to be tested & has several upgrades over 330 bar engine. For reference, 330 bar on Raptor produces ~225 tons (half a million pounds) of force.

Another awesome render! I think people might forget how high 20km is! That’s about twice as high as a commercial airliner flies, so watching Starship bellyflop out of the sky at that altitude will be crazy!!!
Corey@C_Bass3d· Aug 17, 2020With more and more hardware showing up at the construction site, #SN8's 20km hop and belly flop are feeling a little more real, despite how unreal it'll look.

Yeah, Starship will be a tiny dot at 20km. Hard to see with naked eye. We’ll do lots of flights.

Very impressive render. Note, legs will be bigger & there’ll be way more stuff in engine bay. Main engines actually do majority of work in turning ship vertical before landing.

Well someone removed "business magnet 🧲 " from your wiki, imo that can be considered as trashing 🤣

The “early investor” part of Tesla is wrong. That bs has been pushed by Eberhard (worst person I’ve ever worked with and that’s saying something!) for years.

Also, there could be long period comets that intersect Earth right now. We just haven’t observed them during humanity’s (very short) recorded history. Comet S-L 9 punched a roughly Earth-sized hole in Jupiter.

Some big milestones coming up
Matt Cutshall@Booster_Buddies· Aug 17, 2020So, with the #SpaceX Starlink launch on Tuesday, this will be another first for the company.
First time reusing a booster for the 6th time!
And this flight marks the 100th launch for SpaceX and the 92nd for the Falcon 9!

To get a sense for how big the Moon is, first look at Africa. The Moon is 24.5% larger! That’s why we call it “Earth’s 8th continent”. Source: IG/ instagram.com/p/CD1xAm8JaEt/…
