Spacecraft Landing
Spacecraft landing refers to the process of safely bringing a spacecraft to rest on the surface of a celestial body, such as a planet, moon, or asteroid. This process involves a series of complex maneuvers, including deceleration, descent, and touchdown. The spacecraft must be slowed down from its orbital speed to a speed that is slow enough to land safely. This is typically achieved through the use of thrusters, parachutes, or a combination of both. Once the spacecraft is close to the surface, it must be guided to a precise landing location, which may be determined by remote sensing or by onboard instruments. The landing site must be carefully chosen to avoid hazards such as steep slopes, boulders, or other obstacles. Successful spacecraft landings have been achieved on several celestial bodies, including the Moon, Mars, Venus, and asteroids.
