Suborbital flights are space missions that reach the edge of space but do not complete an orbit around the Earth. These flights typically ascend to altitudes above 100 kilometers (62 miles), where passengers can experience a few minutes of weightlessness and see the curvature of the Earth. Companies like Blue Origin and Virgin Galactic are pioneers in this field, offering commercial flights for tourists. Unlike orbital flights, which require significant speed to stay in orbit, suborbital flights follow a parabolic trajectory. After reaching their peak altitude, the spacecraft descends back to Earth, landing safely. This type of flight is often seen as a stepping stone for future space tourism and research opportunities.
