If a flight is planned carefully, a spacecraft can use the gravity of planets and moons to do a swingby or be pulled into orbit. Much of the aiming of spacecraft is done at or near launch, when the huge launch vehicle that puts it into space can push it onto a course that will take it to the right place.
In such a case we speak of orbital space flight. The velocity required to stay in an orbit is called orbital velocity and depends on the altitude of the orbit. For a 200 km circular orbit the orbital velocity is 7780 m/s (28000 km/h or 17400 mph). It is actually this incredibly high speed which makes. space flight technically so complex and therefore expensive.
