Spacecraft Liftoff

Spacecraft liftoff refers to the initial phase of a space mission where a spacecraft is launched from the Earth’s surface into space. This stage involves the ignition and operation of the launch vehicle’s engines, which generate the thrust necessary to overcome Earth’s gravitational pull. Liftoff is a critical moment in a space mission, as it marks the transition from ground operations to flight. It typically follows a countdown sequence and is characterized by the rapid ascent of the spacecraft, during which it may pass through various stages of atmospheric flight before reaching the boundary of space. Successful liftoff is essential for placing satellites into orbit, transporting crewed missions to the International Space Station, or sending probes to other celestial bodies.
