Entered orbit on 20 October 1975; lander landed at 05:13 UTC on 22 October. First orbiter of Venus and first images from the surface of another planet. Proton-K/D: Venera 10 (4V-1 No.661) 14 June 1975: Lavochkin Soviet Union: Orbiter/Lander Successful Entered orbit on 23 October 1975; lander landed at 05:17 UTC on 25 October Proton-K/D: Venera ...
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 ...
Representation of Venus (yellow) and Earth (blue) circling around the Sun. Venus and its rotation in respect to its revolution. Venus has an orbit with a semi-major axis of 0.723 au (108,200,000 km; 67,200,000 mi), and an eccentricity of 0.007.
Venera 1 was launched on 12 February 1961. Telemetry on the probe failed seven days after launch. It is believed to have passed within 100,000 km (62,000 mi) of Venus and remains in heliocentric orbit. Venera 2 launched on 12 November 1965, but also suffered a telemetry failure after leaving Earth orbit.
Venera 7 (Russian: Венера-7, lit. 'Venus 7') was a Soviet spacecraft, part of the Venera series of probes to Venus.When it landed on the Venusian surface on 15 December 1970, it became the first spacecraft to soft land on another planet and the first to transmit data from there back to Earth.
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.
entered orbit: N/A Entered orbit five years after failed orbit insertion on 7 December 2010. Continuing mission to study the atmosphere of Venus. [71] Juno: Jupiter 5 August 2011 4 July 2016 entered orbit: 1,795 days (4 y, 10 m, 29 d) First solar-powered Jupiter orbiter, mission to study Jupiter's interior and magnetic environment. [72]
Vehicle L1-6V steered downrange into a clear blue winter sky and orbit was successfully achieved. [5] The spacecraft, along with the rocket's Blok-L upper stage, was initially placed into a 229-by-282-kilometre (142 mi × 175 mi) low Earth orbit, [1] before the upper stage fired to place "Venera 1" into a heliocentric orbit, directed towards Venus.
