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.

You start to leave the earth in a rocket at 10 am in the morning on a sunny day.As you go up into the sky the sky will get darker and darker until at the edge of space the sky will go black and th stars will come out.he light is still there, but it does not scatter into blue sky like it does with Earth's atmosphere. That's why the sky looks black in outer space. But if you held up a piece â¦ of paper, it would be illuminated very brightly in the sun.
