Russia sent the first probe Venera 1 in 1961.
The first successful Venus probe was NASA's Mariner 2, which confirmed its high surface temperatures In 1966
Venera 3 became the first spacecraft to reach the surface of another planet when it crash-landed on Venus.
Its successor Venera 4 succeeded in returning data during its descent, reporting that the atmosphere of Venus was 95% carbon dioxide and the surface pressure around 100 times greater than on Earth.
Venera 7 made the first successful soft landing in 1970.
In 1975, Venera 9 and 10 were the first spacecraft to enter an orbit around Venus, each also dispatching a lander to the surface.
They were followed by several other NASA and Soviet orbiter/lander missions during the late 1970s and 1980s, including Veneras 11 through 16, Pioneer Venus, and Vega.
Between 1990 and 1994, NASA's Magellan orbiter mapped 98% of the surface using radar.
The European Space Agency's Venus Express arrived in orbit around the planet in 2006, and is currently studying its atmosphere and surface characteristics.
Akatsuki was launched on May 20, 2010, by JAXA, and will enter Venusian orbit in December 2010.
No natural satellites of the planets Mercury or Venus have ever been discovered.
Venus has no moons. It may have had some before but now it has no moons.
Mercury and Venus do not have any natural satellites or moons. They are the only two planets in our solar system that do not have any known moons orbiting around them.
Of the eight true planets in the Solar System, only Mercury and Venus are lacking natural satellites.
No satellites are known to orbit Mercury or Venus.
No natural satellites of the planets Mercury or Venus have ever been discovered.
Venus is one of the few planets that doesn't have any satellites orbiting around it. Venus also is a planet with no moons.
Venus does not have any natural satellites.
No. Venus has no natural satellites (moons). Neither does Mercury.
Since Earth's Moon was likely formed from a chance collision, the formation of moons may not have been a stable process in the inner solar system. Any moons that formed around Venus or Mercury could have been swept away by the stronger gravity of the Sun, as might smaller moons around Earth. If Mercury or Venus ever had satellites, they were lost long ago.
