Hi guys. Will you watch fireworks with me?

I could never dig into watching sports. But I still want bread and games - this is my games.

Do you think the Indians from the jungle come to watch?

If Earth was round, why wouldn't we just bring the rocket around to the other side and drop it? Balltards BTFO

The acceleration at the beginning seems a lot higher than Falcon 9.

It lost 20Km of altitude. This trajectory is retarded.

thats cuz SRB's do that

If SpaceX wanted to spend like 40 million a launch on SRB's, they could do that too

I don't think its a good thing for optimizing payload to accelerate too much in the lower atmosphere

But you get a lot faster to max q instead of wasting propellant to just fight with gravity.

Sure the Falcon 9 is more economical anyway.

>>8950408
But then you have higher aerodynamic losses, and your vehicle needs to be stronger, so I think in terms of payload its all a wash

No. At start you are way beyond optimal speed. After you reach max Q, you throttle down. That's one good reason to use strap-on boosters.
