spacecraft ne demek?

Spacecraft is a general term used to describe any vehicle designed to operate beyond the Earth's atmosphere. There are several types of spacecraft, including satellites, space probes, space shuttles, and crewed spacecraft such as the International Space Station.

Satellites are spacecraft that orbit the Earth and are used for various purposes, including communication, science, navigation, and reconnaissance. They can be classified as either natural or artificial satellites.

Space probes are unmanned spacecraft that are sent on missions to explore the solar system. They often carry scientific instruments to study the planets, asteroids, and comets.

Space shuttles are reusable crewed spacecraft that have been used by NASA to transport astronauts and cargo to and from orbit. They were in service from 1981 to 2011 and were retired due to their high cost of maintenance and operation.

Crewed spacecraft such as the International Space Station are designed to support human life in space for extended periods of time. They are used for scientific research, space exploration, and testing new technologies.

Overall, spacecraft have played a crucial role in advancing our understanding of the universe and expanding human presence in space.
