why do modern rockets blast off with zero initial velocity (standing straight up)?
The biggest difficulty in getting enough speed to get to orbital velocity is how the earth's atmosphere slows you down. It is most effective to blast straight up until the atnosphere becomes thinner and the drag caused by the air becomes very low, then level out and accelerate sideways towards an…
The Short Answer
The biggest difficulty in getting enough speed to get to orbital velocity is how the earth's atmosphere slows you down. It is most effective to blast straight up until the atnosphere becomes thinner and the drag caused by the air becomes very low, then level out and accelerate sideways towards an orbital speed. Also turning while in atmosphere is very difficult to do, again due to drag wanted to slow down any surfaces that aren't aerodynamic to the direction of travel.
