Quite simply, this is any space vehicle that does not have a live crew of humans or animals on board. All communications, military and meteorological machines that are orbiting the Earth are unmanned satellites, as are the probes that we have sent to other planets in our Solar System.
Sputnik 1, launched by the USSR (Russia) on October 4, 1957, was the first artificial satellite to successfully achieve Earth orbit. There had been several previous unsuccessful attempts by the USSR and the USA.
They were unmanned, although Sputnik 2 carried a dog into space.
Unmanned. Explorer I, launched February 1, 1958, was the first US artificial satellite. It was approximately 4 feet long and 8 inches in diameter (1.2 m by .2 m) and weighed 30 lb. (14 kg).
satellite is satellite
Answer: 1.communication satellite 2.navigational satellite 3.weather satellite 4.millitary satellite 5.scientific satellite 6.satellite launches. It composed of 6 satellites...........i hope.....my answer can help you.....
Unmanned
an unmanned space probe is a satellite orbiting around the planet
No one was onboard Sputnik, it was an unmanned satellite.
an unmanned device that uses technology and sends information back to earth
neither it is usually referred to as a launch vehicle. a space probe is unmanned and transmits data back to earth and a space satellite is something that orbits the earth. you could call the shuttle a satellite but it is not normally referred to as that.
Unmanned Aircraft and spaceships are called a variety of names. These are the most common: Drone, Rocket, Droid, Probe, and Satellite.
Space stations are manned vehicles used for scientific research. Satellites are unmanned robotic vehicles for scientific research.
yes it showed that soviet science was more advanced than that of the americans'. for a while anyway...
A space probe is an unmanned spacecraft designed to explore the solar system and transmit data back to earth.A satellite is an object that orbits around a planet.By these definitions the space shuttle is not a space probe and is only sometimes a satellite. It is considered a satellite only when it is in orbit around Earth.However, the space shuttle is not usually referred to as a 'satellite' no matter if it is in orbit or not. Normally it is called a 'launch vehicle.'
The satellite sent to explore Pluto was called Charon. Charon is not the satellite on the way to Pluto. Charon is a satellite (moon) of Pluto. The satellite currently on the way to explore Pluto is called New Horizons. It is expected to arrive July, 2015.
Manned spacecraft generally require a much higher data collection time than unmanned stations
There are no people on it. That means it is unmanned.
