What is the difference between orbital and suborbital space flights?
December 18, 2009 7:52PM
An Orbital space flight simply means that you have accelerated a space craft fast enough so it stays in orbit (cicular path) around the Earth.
A suborbital flight means you have reached the limit of space (anything over 100 km high) but not enough speed to completely circle the Earth.
