Original Note:
SpaceShipTwo (first image) is a suborbital spacecraft. This means that it falls on a ballistic trajectory and will not stay up on its own. The Hubble Telescope (second image) is orbital, meaning that it can stay in space without needing constant propulsion. https://en.wikipedia.org/wiki/Orbital_spaceflight?wprov=sfti1
