The planet was observed by the Mariner 10 space probe from March 29, 1974 to March 16, 1975.
This was the only close observation until three flybys by the Messenger probe on January 14, 2008, October 6, 2008, and September 29, 2009. Messenger will begin its orbital mapping of Mercury on March 18, 2011
As of Oct 2009 no space craft has visited Ceres.
The Dawn Mission which was launched on 27 September 2007, will explore Ceres in 2015.
Yes. Several. In fact, every man-made space probe, regardless of what or where it was ultimately designed
to explore, has visited earth at one time or another.
No. The only object other than Earth that people have been to is the moon.
Yes. The first successful landing was in 1970. The first to fly past Venus was in 1962.
No, but one will in 2014 or 2015
Jupiter is the next planet after Mars, but there is small minor planets in between that's within the asteroid belt, with best known been ceres, expected to be explored by the Dawn Spacecraft in 2015.
Currently no clear pictures if any dwarf planet exist, as none have been visited by a spacecraft. In 2015, however, the New Horizons spacecraft will fly by Pluto, and the Dawn spacecraft will enter orbit around Ceres.
Jupiter ;)
Challenger deep is in the ocean, it was never explored by spacecraft.
No. The weather and conditions on the dwarf planets are too extreme for any technology or human life.

Yes, since the 70's
Not yet.The robotic spacecraft Dawn will get there sometime in 2015. It technically still won't be on Ceres but in orbit around it.
Mars.!!! However, spacecraft have landed on Venus, but the atmosphere on Venus is such that spacecraft are crushed/collpase. So no exploration has been done on Venus.
No, but a space probe called New Horizons is on its way for a flyby.

The mariner spacecraft explored Mercury, Mars, and Venus. The first successful space probe and first spacecraft visit to a planet was Mariner 2.
No. The weather and conditions on the dwarf planets are too extreme for any technology or human life.
The Magellan spacecraft was launched to study Venus by NASA on May 4th 1989.
No spacecrafts have currently landed or orbited Makemake. The dwarf planet is too far from the Sun (7,800,000,000 kilometers), it would be in the next century when we can send spacecrafts there.
