Spacecraft

Dear teacher, dear students,
My names is xxxxx, Iam from xxxxx and I am a student Faculty of Manufacturing Technologies of Technical University of Košice with a seat in Prešov.
And now I would like to present my topic about Spacecraft.

A spacecraft is a vehicle or machine designed for spaceflight. On a sub-orbital spaceflight, a spacecraft enters outer space but then returns to the planetary surface (such as Earth) without making a complete orbit. For an orbital spaceflight, a spacecraft enters a closed orbit around the planetary body. Spacecraft used for human spaceflights carry people on board as crew or passengers. Spacecraft used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft that leave the vicinity of the planetary body are space probes. Robotic spacecraft that remain in orbit around the planetary body are artificial satellites. Starships, which are built for interstellar travel, are so far a theoretical concept only.
