The V-2 was the world’s first long-range guided ballistic missile. The liquid-propellant rocket engine used to launch the missile was developed in Germany as a “defense weapon” during World War II. Essentially, it was a weapon used to attack the Allies instead of the Allied forces attacking German cities. With the vertical launch of the MW 18014 on June 20, 1944, the V-2 rocket became the first man-made object to cross the Carmen line and be used for space travel.
‘Flying’ is a very complex process, whether through the Earth’s atmosphere or beyond space. The spacecraft are technically complex, large, and heavy enough to safely return passengers. Cars and buses run on the road because of the frictional surface. To fly a plane through the sky requires the force of the air. However, rockets need to travel into space without friction or buoyancy.
Space travel is a very complex task, as they have to be controlled from the ground, outside the rocket.
