Answer Wiki. If a rocket went straight up, it would either continue in that direction and leave Earth, or it would fall back down, depending on its velocity. Most rockets intend to enter orbit, which is an elliptical trajectory, and it's much more efficient to arc into this trajectory than to go straight up and then accelerate laterally.

So at a million miles an hour it would take 93 hours, but no rocket has ever gone that fast.f you could get a rocket to go 66,000 MPH, which is STILL faster than any rocket has even gone, that would cancel out the speed it started with on Earth due to the Earth orbiting the Sun and it would fall into the Sun due to the Sun's gravity.
