1. The curved path followed by an object or spacecraft that has achieved or exceeded escape velocity and is leaving the gravitational field of a celestial body
The rocket's escape trajectory was carefully calculated to ensure it would break free from Earth's gravity.
A trajetória de escape do foguete foi cuidadosamente calculada para garantir que se libertaria da gravidade da Terra.
2. In physics and astronomy, the specific path required for an object to overcome the gravitational pull of a planet or star and move into space
Engineers studied the escape trajectory needed for the satellite to reach interplanetary space.
Os engenheiros estudaram a trajetória de escape necessária para o satélite alcançar o espaço interplanetário.
