Pluto. That is now a dwarf planet. :)
The Space Probe Galileo was put into orbit around the planet Jupiter

The Russian space probe Mars 2 went to space in the year of 1973.
The Moon
If you jump too high on any planet, you will go into space, especially Earth.
pros. A computerized and minimally mechanized space probe would have only a small fraction of the needs and equipment of a human housing space ship. This would save on mass and therefore fuel. A mechanized probe has a lot less functioning parts therefore there is less that can go wrong with it. A mechanized space probe could survive the years that it take to get to its destination. Humans tend to get bored and psychotic.
No probe has landed on Mercury, however Mariner 10 and Messenger have both surveyed Mercury. Messenger is due to go into orbit around Mercury in 2011 to survey and map the entire planet.
yes he did go to space
The purpose of a probe is to independently visit outer space and sent us the photos and data. No.
Pluto. But it's no longer a planet, so technically none
go sourly lemony
It is a telescope placed in space (like the hubble telescope). When placed in space the telescope does not have to "look" through the earth's atmosphere so its images are not destorted.
