Rockets return to Earth by following a series of carefully planned maneuvers. First, they ignite retro-rockets to slow down. As they re-enter the atmosphere, the aerodynamic shape and heat shields protect the structure from intense heat. Parachutes or controlled burns slow the descent further for a safe landing. Modern rockets often have landing legs and guidance systems for precision in landing sites.
FAQs & Answers
- What are retro-rockets and how do they work? Retro-rockets are engines that fire opposite to the rocket's direction of travel to slow it down during descent.
- What role do heat shields play in rocket re-entry? Heat shields protect rockets from the intense heat generated during re-entry into Earth's atmosphere.
- How do parachutes contribute to a safe rocket landing? Parachutes deploy to slow down the descent of the rocket, ensuring a softer landing.
- What technologies help in precise rocket landings? Modern rockets use guidance systems and landing legs for accuracy during the landing phase.
