The Soviet probes Phobos 1 and 2 were sent to Mars in 1988 to study Mars and its two moons. Phobos 1 lost contact on the way to Mars. Phobos 2, while successfully photographing Mars and Phobos, failed just before it was set to release two landers to the surface of Phobos.
Following the 1992 failure of the Mars Observer orbiter, the NASA Mars Global Surveyor achieved Mars orbit in 1997. This mission was a complete success, having finished its primary mapping mission in early 2001. Contact was lost with the probe in November 2006 during its third extended program, spending exactly 10 operational years in space. The NASA Mars Pathfinder, carrying a robotic exploration vehicle Sojourner, landed in the Ares Vallis on Mars in the summer of 1997, returning many images.
The NASA Phoenix Mars lander arrived on the north polar region of Mars on May 25, 2008. Its robotic arm was used to dig into the Martian soil and the presence of water ice was confirmed on June 20. The mission concluded on November 10, 2008 after contact was lost.
The Dawn spacecraft flew by Mars in February 2009 for a gravity assist on its way to investigate Vesta and then Ceres.
Spirit Rover (MER-A) was active from 2004 until 2010, when it stopped sending data. Current missionsThe NASA Mars Odyssey orbiter entered Mars orbit in 2001. Odyssey's Gamma Ray Spectrometer detected significant amounts of hydrogen in the upper metre or so of regolith on Mars. This hydrogen is thought to be contained in large deposits of water ice.
The Mars Express mission of the European Space Agency (ESA) reached Mars in 2003. It carried the Beagle 2 lander, which failed during descent and was declared lost in February, 2004. In early 2004 the Planetary Fourier Spectrometer team announced the orbiter had detected methane in the Martian atmosphere. ESA announced in June 2006 the discovery of aurorae on Mars.
In January 2004, the NASA twin Mars Exploration Rovers named Spirit (MER-A) and Opportunity (MER-B) landed on the surface of Mars. Both have met or exceeded all their targets. Among the most significant scientific returns has been conclusive evidence that liquid water existed at some time in the past at both landing sites. Martian dust devils and windstorms have occasionally cleaned both rovers' solar panels, and thus increased their lifespan.
On March 10, 2006, the NASA Mars Reconnaissance Orbiter (MRO) probe arrived in orbit to conduct a two-year science survey. The orbiter will map the Martian terrain and weather to find suitable landing sites for upcoming lander missions. The MRO snapped the first image of a series of active avalanches near the planet's north pole, scientists said March 3, 2008.
The joint Russian and Chinese Phobos-Grunt mission to return samples of the Martian moon, Phobos, launched in 2011. The spacecraft missed its opportunity to enter an orbit that would bring it to Mars, so it has failed its planned mission. En routeThe Mars Science Laboratory, named Curiosity, launched on 26 November, 2011, and plans reach Mars in August 2012. It is larger and more advanced than the Mars Exploration Rovers, with a movement rate of 90 m/h. Experiments include a laser chemical sampler that can deduce the make-up of rocks at a distance of 13 m. Future missionsIn 2008, NASA announced MAVEN, a robotic mission in 2013 to provide information about the atmosphere of Mars. In 2018 the ESA plans to launch its first Rover to Mars; the ExoMars rover will be capable of drilling 2 m into the soil in search of organic molecules.
The Finnish-Russian MetNet, is mission concept where multiple small vehicles on Mars to establish a widespread observation network to investigate the planet's atmospheric structure, physics and meteorology. MetNet was considered for a piggyback launch on the Russian Phobos-Grunt mission, but not selected.

New Horizons is the only one i know it is expected to arrive on July 2015 or that is what I heard
Venera 3 November 16 1965,1st of March 1966 Venus and the capsule parachuted down
the Cassinni in 2004
cassini and in 2004
It has had satellites and robots.
Voyager2 on 1989
venus has no sattelite
cassinni in 2007
so far only one satellite has been sent to venus and that one satellite is venera it was sent in 1965
Yes. Jupiter was first visited on flyby missions by Pioneer 10 in 1973 and by Pioneer 11 in 1974. The space probe Ulysses encountered Jupiter when it was placed in a large orb…it around the sun in 1992. It made a later encounter in 2004. The Galileo probe orbited Jupiter from 1995 until 2003 when its mission ended with a burn into the planet's atmosphere. Galileo sent an atmospheric probe to Jupiter in 1995. In 2000 the space probe Cassini flew by Jupiter for a gravitational slingshot on its way to Saturn (which it reached in 2004) and took joint measurements of Jupiter with Galileo. Finally in 2007 the New Horizons space probe took some readings of Jupiter as it executed a slingshot around the planet while on its way to Pluto.
There's a robot on Mars call, "The Mars Rover" if that is what you are talking about
It is a Mars rover.
The various probes sent to observe Jupiter are:Pioneer 10 - 1973Pioneer 11 - 1974Voyager 1 - 1979Voyager 2 - 1979Ulysses - 1992Cassini - 2000New Horizons - 2007Galileo orbital… mission - 1995–2003Juno - launched in 2011, and expected to arrive in 2016
Venera 15 and 16 orbited the planet in 1983 Magellan in 1990 mapped 98% of the surface Venus Express is still sending data back to earth.
