Closeup of the titanium grid fins. Not painted, as they glow red hot during a fast reentry.

Is this the first closed loop version? I thought some of the early attempts ran out of hydraulic fluid due to it being open
Elon Musk
@elonmusk · 25. Juni 2017
We used to have a (lame) open loop hydraulic system, but that was upgraded to closed about 2 years ago

But does it have Bluetooth?

Was the hard landing due to improper preprogrammed parameters or needing a fourth engine to decelerate from higher velocity?
Elon Musk
@elonmusk · 25. Juni 2017
Rocket was suddenly slammed sideways right before landing. Heavy gust or something malfunctioned onboard. Reviewing telemetry.

Also probably means the first stage can glide further
Elon Musk
@elonmusk · 25. Juni 2017
True, but that's a minor factor for rockets

No, but shielding got fragged every flight. More control authority is for Falcon Heavy, but also enables Falcon 9 to land in heavier winds.

Do the larger fins require more hydraulic fluid for the standard recovery profile?
Elon Musk
@elonmusk · 25. Juni 2017
They will, but the hydraulic system is closed loop, so no fluid lost. They do need more power & energy, but rocket has plenty of that.

Are they heavier than the originals?
Elon Musk
@elonmusk · 25. Juni 2017
Slightly heavier than shielded aluminum, but more control authority and can be reused indefinitely with no touch ups

Flying with larger & significantly upgraded hypersonic grid fins. Single piece cast & cut titanium. Can take reentry heat with no shielding.

@elonmusk any plans to increase the battery size up from 100kwh (or even supporting an range upgrade in the future with the current 100D)?
Elon Musk

It's an aluminum honeycomb cartridge, so only a couple of hours to replace

Rocket is extra toasty and hit the deck hard (used almost all of the emergency crush core), but otherwise good

Falcon 9 will experience its highest ever reentry force and heat in today's launch. Good chance rocket booster doesn't make it back.

Lucky for you @elonmusk it is on Earth. Consider this your personal invitation to take a test drive.
