It also made global maps of Venerean surface temperatures, and attempted to observe signs of life on Earth from a distance. Venus Express successfully assumed a polar orbit on April 11, 2006. The mission was originally planned to last for two Venusian years (about 500 Earth days), but was extended to the end of 2014 until its propellant was ...

The last time Venus drew nearer than 39.5 million km was in 1623, but that will not happen again for many millennia, and in fact after 5683 Venus will not even come closer than 40 million km for about 60,000 years. [8] The orientation of the orbits of the two planets is not favorable for minimizing the close approach distance. The longitudes of ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Consequently, Venus transits only occur when an inferior conjunction takes place during some days of June or December, when the orbits of Venus and Earth cross a straight line with the Sun. [189] This results in Venus transiting above Earth in a sequence currently of 8 years, 105.5 years, 8 years and 121.5 years, forming cycles of 243 years.
First docking between two crewed spacecraft in Earth orbit. First crew exchange in space. USSR Soyuz 4 and Soyuz 5: January 1969: First spacecraft to parachute in Venus's atmosphere, lost contact before landing. USSR Venera 5: 23 May 1969: First docking of two crewed spacecraft around another celestial body. First lunar mission to include a ...

It consisted of an orbiter and a lander. It was launched on June 8, 1975, at 02:38:00 UTC and had a mass of 4,936 kilograms (10,882 lb). [5] The orbiter was the first spacecraft to orbit Venus, while the lander was the first to return images from the surface of another planet. [6]
