Satellites without people. For the United States that's all space flights except the Suttle and International Space Station, both with depend on human beings.
Satellites are unmanned spacecraft, and the term unmanned space vehicle could also apply. A spacecraft is a vehicle or machine that is used in space, and there are many different kinds with a variety of missions. Satellites are used for communications, navigation, and planetary observation (including exporation, meteorology and intelligence gathering) to name a few of their applications.

All satellites, rovers, manned and unmanned rocketships
Rockets have sent unmanned spacecraft to mars and Jupiter. Satellites put in orbit by rockets beam back information about earth's atmosphere and weather.
We see deep into space by using optical or radio telescopes, either from the Earth's surface, from satellites orbiting above us, or carried out into space on an unmanned spacecraft.
Unmanned
satellites with humans and without humans
Spacecraft is the generic term there are both manned and unmanned types such as satellites for the unmanned variety.

All space telescopes are unmanned - unless you want to count the small telescopes on the Shuttle or IIS as space telescopes.

The sputnik series of satellites were unmanned. Sputnik II carried an expendable dog.
Currently all missions to Mars are unmanned. The only human aspect of these missions are the scientist and engineers that build the satellites or rovers/landers and the people that control them (mission control).
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.
The USSR (now called Russia) sent the first unmanned and manned satellites into earth orbit.
Space stations are manned vehicles used for scientific research. Satellites are unmanned robotic vehicles for scientific research.
