Why did #SpaceX keep #Starship’s Grid Fins out on ascent?

[aidankreltszheim]

Didn’t realise how big the fins were. Gives you a sense for how massive the ship is.

Holy sh/t the shot at the end.. i didn't know they are that huge

Holy hell seeing the grid fins on the ground like that really puts it into perspective. Did not realize they were that massive.

Seeing a person standing next to that grid fin was a bit shocking because until that point. I really had no concept of how big they actually are. I love moments like that Where you have a new point of reference that just catches you off guard because you didn't realize the actual scale of something is wayyy bigger than it originally looked.

Remind me of one of those bike pedals that sends you straight to hell when it accidentally hit your shin

Interesting, it’s amazing how the weight savings of the unit offset the fuel use during assent. Thanks for the update.

You should do more shorts, it's a great way to get more people to see your stuff and teach smaller details like this!

Engineers: It doesn't matter if it's flying at an angle of 3 degrees or less.

Starship: *proceeds to fly at 90, 180, and 270 degrees on first test flight*

It is unbelievable how massive those fins are!!! Really puts it into perspective how big the whole rocket is.

[Crunch_dGH]

The fins are designed to work at around Mach 5 reentry speeds from high altitudes. Also, low speed upon launch = low drag, while less dense air with heights = decreasing drag potentials from increasing speeds.

The close look at the grid fin helped have a realistic idea of how big it is and wow about how it actually works in real-time helping the rocket maintain balance. Incredible, thanks.

The amount of knowledge you have about complex systems like rockets is amazing, the rocket engine videos are soo good. I only knew they are complicated, but now I know why they complicated, thanks to you.
All my life I’ve heard the phrase ‘Rockets are controlled explosions’ I truly under estimate the precision of that control. Keep going.

[andrewmetasov]

That's one of the best shorts I've ever seen so far on YT

[josephrothenberg]

Loving the shorts man! Keep up the awesome work.

[danielcantwell]

Yay an Everyday Astronaut short. I love these little videos between the long ones so please make more Tim!

[vermilin]

Wow look at the size of those grid fins and you get a scale of how big these rockets truly are. Blows my mind how amazing these machines are!!!

[xenotemos]

the rocket made several full spins and still managed to keep its integrity, that's impressive

[Praktical_]

Dude that shot of the engines moving all in sync was beautiful

[mrcarljfisher]

Never thought I would see Tim manage a 30 second video! XD concise and well explained, great job!

[markojovanovic]

I didn't expect them to succeed but they surprised me and managed to make a launch vehicle that works. Congratulations!
