  1. There have been 46 space missions to the planet Venus (including gravity-assist flybys). Missions to Venus constitute part of the exploration of Venus. The Soviet Union, followed by the United States, have soft landed probes on the surface.

  2. Nov 9, 2017 · Dozens of spacecraft have launched to explore Venus, but not all have been successful. NASA's Mariner 2 was the first spacecraft to visit any planet beyond Earth when it flew past Venus on Dec. 14, 1962. NASA is planning two new missions to Venus: VERITAS, and DAVINCI.

    • Venus Express. The European Space Agency's Venus Express studied the planet's ionosphere and atmosphere, enabling scientists to draw important conclusions about the surface.
    • MESSENGER. NASA's MESSENGER spacecraft flew past Venus twice on its way to Mercury.
    • Cassini-Huygens. NASA and the European Space Agency's Cassini-Huygens mission visited Venus twice during its long trek out to Saturn.
    • Magellan. NASA's Magellan orbiter mapped over 98% of Venus at a resolution of 100 meters or better using its radar.
  3. The mission is timed for launch when Earth and Mars are in good positions relative to each other for landing on Mars. That is, it takes less power to travel to Mars at this time, compared to other times when Earth and Mars are in different positions in their orbits.

    The former Soviet Union started off the race to Mars with a series of Mars spacecraft. Among them, the Mars 1 mission was able to send back some data about the Red Planet before mission controllers lost contact with it a few months after launch. Mars 2 got to Mars safely, but its rover crashed landed on the surface. Mars 3, 4, 5 and 6 were partiall...

    Mariner 9 arrived during a planet-wide dust storm and successfully put itself into orbit. After the dust settled, the spacecraft returned 7,329 images that revealed 85 percent of the surface of the planet. Those images revealed surface features familiar to us on Earth, including river beds, craters, flood plains, canyons, and volcanic features. In ...

    The bad luck with missions continued into the 1990s with the loss of NASA’s Mars Observer mission in 1993. An investigation suggested that a fuel leak may have caused the mission to fail. Mars 96 failed at launch in 1996, the Japanese Nozomi (Planet B) mission never entered Mars orbit. The Mars Climate Orbiter (NASA) crashed to the Martian surface ...

    In the first two decades of the 21st century, space agencies have had more successful missions. NASA’s Mars Odyssey, the European Space Agency’s Mars Express led off the march to Mars. They are still currently operating as of this writing. The Mars Exploration Rovers A and B, also known as Spirit and Opportunity, settled onto the Martian surface in...
