Yes, since the 70's
Besides Earth, mars is the most explored planet.
The Mars Rover has explored Mars and "Spirit" is the spacecraft that was sent on November 2011 and is going to Mars.
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.
No, the Mars Pathfinder is not a satellite. It was a robotic spacecraft that landed on Mars in 1997 and deployed a rover called Sojourner to explore the surface of the planet. Pathfinder was designed to study the Martian surface and climate, as well as test new technologies for future missions.
Mars has constantly been visited by spacecrafts. The first spacecraft to visit Mars was the Mariner 4. After that Mars has been visited by numerous spacecrafts like: Mars Pathfinder, Mars Global Surveyor, Mars Odyssey, Mars Express and the Mars 2 which was the first spacecraft to land on Mars.

yes but what kind
The mariner spacecraft explored Mercury, Mars, and Venus. The first successful space probe and first spacecraft visit to a planet was Mariner 2.
As of yet, there have been no manned Mars spacecraft at all.
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.
No, no humans have traveled to Mars yet. However, there have been robotic missions by spacecraft like the Mars rovers and landers that have explored the surface of Mars. NASA is planning for future manned missions to Mars, but as of now, nobody has been there.
The Mars satellite that crashed on Mars was the Mars Climate Orbiter. It crashed in 1999 due to a navigational error caused by a mix-up of imperial and metric unit systems during the spacecraft's mission.
Three spacecraft that have explored Mars are the Mars rovers Spirit, Opportunity, and Curiosity. These robotic vehicles have conducted various experiments to study the Martian surface, geology, and atmosphere since landing on the planet.
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.
