Top Spaceship PNG Images
A spaceship or spacecraft is a machine or a vehicle designed to fly in outer space. Spaceships are used for a wide range of purposes, being a typical kind of artificial satellite, the uses include communications, meteorology, space colonization, transportation of humans and cargo, earth observation, navigation and planetary exploration. All the spaceships require a launch vehicle, which means that they cannot get into space on their own, except single stage to orbit vehicles. When the space vehicle enters the space and returns back to the surface, it is said to be on a suborbital space flight, this is due to not having gained sufficient velocity or energy to make a full orbit of the earth. When the spaceship enters close orbits around the Earth or around other celestial bodies, it is said to be in an orbital spaceflight.
Spaceships used for carrying humans humans into space i.e. human spaceflights, tend to carry people on board as passengers or crew from start or on orbit (space stations) only, however those spaceships that are used for robotic space missions operate either telerobotiacally or autonomously. Space probes are robotic spaceships used to support scientific research. Artificial satellites are nothing but a robotic spaceship that remain in orbit around a planetary body.
