technically speaking it takes less fuel to launch vertically and since money and weight are extremely important
not to mention that you don't need a 8 mile long modified air strip just to launch
Russia.
No, spaceships cannot bounce off the atmosphere. When entering the Earth's atmosphere, spaceships experience atmospheric drag which slows them down, causing them to eventually descend and land or burn up if they are moving too fast.
Spaceships can fly, but need certain materials for lift off.

No it can't, but an F-15 can.
Spaceships take off from Earth or other celestial bodies by using rocket propulsion. Rockets generate thrust by expelling high-speed exhaust gases, pushing the spaceship upwards against gravity. The exhaust gases are usually produced by burning a fuel and an oxidizer in a controlled combustion process.
The Harrier's short wings allow it to take off both ways.
