while entering Earth's atmosphere, it totally destroy & comes as single probe, so how spacecraft s are reusable for new missions also?
It's not clear what you're referring to but not everything that is launched into space gets reused. Most satellites will eventually fall back to earth, burn up in the atmosphere and naturally won't get reused. For something the U.S. Space Shuttle, the solid rocket boosters and the shuttle itself were reusable. The external fuel tank was not recycled. Similarly, the crew module for the Orion spacecraft is also designed to be reused. When it's recovered, it is examined, checked for damage and prepared for its next flight.Ganesh Ujwal said:while entering Earth's atmosphere, it totally destroy & comes as single probe, so how spacecraft s are reusable for new missions also?
Spacecrafts are equipped with heat shields that protect them from the intense heat and friction experienced during re-entry into Earth's atmosphere. They also have parachutes that slow them down as they approach the ground, allowing for a safe landing.
The most commonly reusable components of a spacecraft are the main body or structure, engines, and some types of propellant tanks. These components are designed to withstand the harsh conditions of space and can be refurbished for future missions.
After returning to Earth, reusable components of a spacecraft are thoroughly inspected and cleaned. Any necessary repairs or upgrades are made, and the spacecraft is then reassembled and tested to ensure it is ready for another mission.
The number of times a spacecraft can be reused depends on its design and the type of mission it is used for. Some spacecrafts, like the Space Shuttle, were designed to be reused multiple times, while others may only be used once or a few times before being retired.
There are some limitations to reusing a spacecraft for a new mission. For example, certain components may degrade over time and may need to be replaced, and the spacecraft may need to be modified or upgraded for a different type of mission. Additionally, the cost and resources required for refurbishing a spacecraft may make it more practical to build a new one for certain missions.
