[http://en.wikipedia.org/wiki/Mariner_2 Mariner 2] noticed the cloud tops were cool and the surface was very hot

Yes, they have, but they were all destroyed by the heat and pressure. The spacecraft are: Venera 8 and Venera 7 sent by the Soviets.
What time?
Yes. The USSR and the USA have explored Venus.

yes venus was explored by a robotic spacecraft. one of the first to reach vicinity of another planet and returned data the u.s mariner 2in it's flyby of venus in 1962. since then venus has been a target of over 20 spacecraft.
yes,because there were space-probes and unnamed crafts that found Venus dust-covered and windy
i guess the robots from in space they thought 'oh lets try to look at another planet' so they did. thats just my guess < __ >
Yes, quite a few robotic probes have been sent to Venus by the United States and the Soviet Union.
There haven't been any probes sent to Eris.
I am certain that Voyager1 and Voyager2 in the '70s.

Yes there was, all space crafts that successfully got information from Venus were the Mariner 2, 5 and 10, Venera 4-16, vegal 2, and pioneer Venus 1 and 2
yes,because there were space-probes and unnamed crafts that found Venus dust-covered and windy

yes voyager 2
Simple!Space is explored so that we know where we are and the things that surround our planet. So that we can find out if there is any other form of life somewhere else in the universe and beyond. Its explored so that we know whats out there, and so we have heaps of knowledge about space.
Yes, quite a few robotic probes have been sent to Venus by the United States and the Soviet Union.
none with humans although some probes have
There haven't been any probes sent to Eris.
