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.
There have been many space probes to Venus. Here are a few important ones: * Mariner 10 (NASA) * The Venera series of probes (Roscosmos) * Magellan (NASA) * Venus Express (ESA) (check related link)
You can get these at some craft stores. It might also be a good idea to find some online and have them sent to you.

On June 18th of 2009, NASA sent a probe in space called LCROSS (Lunar CRater Observation Sensing Satellite) to crash into the south region of the moon near the Cabeus crater. On the 9th of October of that same year, the space craft crashed into its target with dead aim precision. the LRO or Lunar Reconnaissance Orbiter, another probe sent at the same time as LCROSS took spectrometry data from the cloud of debris that was ejected from the surface of the moon seconds after LCROSS impacted the Earths natural satellite. Spectrometers look at gases and by looking at the rate of absorption of light, scientist can determine was molecules are in the substance being observed, since each molecule has its very own unique spectrum lines (the colors of the rainbow). for example if looking at mercury gas we would see blue green and orange lines of color where as in hydrogen gas we would see violet blue aqua and red. The data from the spectrometers show very clearly that the spectrum for water in present.
NASA has sent several unmanned space probes to Saturn, but no manned missions.
NASA has sent a number of space craft to Mars, including a surveyor and several rovers. More missions are planned.
Yes, NASA has sent a couple of unmanned probes to examine Mercury, Mariner 10 which did a flyby and the MESSENGER orbiter.
Unmanned space probes in the early years of the Space Race have been sent to close to planets like Saturn, Uranus, and Neptune.
normally they are unmanned but sometimes they do have people sent up
NASA sent it by remote control space ship.
A space probe is an unmanned spacecraft sent into space.
NASA has sent a total of 5 space crafts to mars.
The most obvious answer to your question is the fact that people have to return to earth, while an unmanned craft can stay in space infinitely. Manned spacecraft require things like oxygen, water, food and communications equipment, none of which are required by an unmanned spacecraft. That means unmanned spacecrafts can be sent into space for a fraction of the cost of a manned spacecraft. So basically, it's much cheaper and safer to send unmanned spacecrafts to explore the universe.
To date there have been 282 manned missions sent into space and more than 1000 unmanned missions.
It named Terra.
The first laptop was sent into space with Nasa.
