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
What else can I help you with?
What planet is after Mars?
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.
Do you have pictures of the three dwarf planets if you do show me?
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.
What planet was recently explored by the Galileo spacecraft?
Jupiter ;)
Which pace craft explored the Challenger Deep?
Challenger deep is in the ocean, it was never explored by spacecraft.
Has there every been any spacecraft travel to dwarf planet Ceres?
No. The weather and conditions on the dwarf planets are too extreme for any technology or human life.

Are there robots on Ceres?
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.
Which planets have not been visited by a spacecraft?
Depends on whether you say Pluto is a planet or not. If you say it isn't, then there are no planets that haven't been visited by a spacecraft. If you say it is, then there is one that hasn't been visited yet, but one is on the way.
Has Pluto ever been explored by a spacecraft or fly by?
No, but a space probe called New Horizons is on its way for a flyby.

Which planets did the the mariner spacecraft explore?
The mariner spacecraft explored Mercury, Mars, and Venus. The first successful space probe and first spacecraft visit to a planet was Mariner 2.
What planet was explored by the Magellan spacecraft?
The Magellan spacecraft was launched to study Venus by NASA on May 4th 1989.
What is the most explored planet?
Besides Earth, mars is the most explored planet.
What planet is the only one on which unmanned spacecraft have successfully landed and explored?
Venus is the only planet where unmanned spacecraft have successfully landed and explored. The Soviet Union's Venera program landed several probes on Venus in the 1970s and 1980s, providing valuable data about the planet's atmosphere and surface conditions.
