You can (theoretically) reach "space" with a single impulse from earth's surface, but you cannot achieve earth orbit that way. To make orbit, you need a circularization burn at apogee to raise your perigee above the atmosphere. Otherwise, its ballistic trajectory will cause your spacecraft to re-enter the atmosphere.
