Yes, rockets can leave Earth's orbit. Achieving this requires reaching the escape velocity of approximately 11.2 km/s. Rockets use powerful engines and multiple stages to achieve this speed. The journey is meticulously planned, with careful calculations for fuel, trajectory, and gravitational forces. Once beyond Earth's gravity influence, they can travel to other celestial bodies.
FAQs & Answers
- What is escape velocity? Escape velocity is the minimum speed an object must reach to break free from a planet's gravitational pull. For Earth, it's about 11.2 km/s.
- How do rockets achieve escape velocity? Rockets achieve escape velocity by using powerful engines and multiple stages to increase their speed gradually to the required level.
- Can humans leave Earth's orbit? Yes, humans can leave Earth's orbit; this has been accomplished during missions to the Moon and beyond.
- What happens after a rocket leaves Earth's gravity? Once a rocket leaves Earth's gravity, it can navigate through space to reach other celestial bodies, following planned trajectories.
