Venus Express (VEX) was the first Venus exploration mission of the European Space Agency (ESA). Launched in November 2005, it arrived at Venus in April 2006 and began continuously sending back science data from its polar orbit around Venus.
Venus Express was a mission by the European Space Agency to study the atmosphere and surface characteristics of Venus from orbit. The design was based on ESA's Mars Express and Rosetta missions. The probe's main objective was the long-term observation of the Venusian atmosphere, which it is hoped will also contribute to an understanding of ...
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. Venera 7 was the first lander overall and first for the Soviet Union, touching down on 15 December 1970. Pioneer Venus 2 contained the first spacecraft to land from the United States, the Day ...
The European Space Agency has officially adopted two new space missions to study Venus from its atmosphere to inner core and to search for gravitational waves. ... Venus Express, which orbited ...
In April 2006, Venus Express, the first dedicated Venus mission by the European Space Agency (ESA), entered orbit around Venus. Venus Express provided unprecedented observation of Venus's atmosphere. ESA concluded the Venus Express mission in December 2014 deorbiting it in January 2015. [228]
With current propulsion systems, launch windows to Venus occur every 584 days, [3] compared to the 780 days for Mars. [4] Flight time is also somewhat shorter; the Venus Express probe that arrived at Venus in April 2006 spent slightly over five months en route, compared to nearly six months for Mars Express. This is because at closest approach ...
Venus Express observed two large shape-shifting vortices on Venus' poles (polar vortices) in 2006 on one of its close-up flybys of the planet.The south pole was seen to have a large, constantly changing, double-eye vortex through high-resolution infrared measurements obtained by the VIRTIS instrument on Venus Express.
The Magellan spacecraft was a 1,035-kilogram (2,282 lb) robotic space probe launched by NASA on May 4, 1989. Its mission objectives were to map the surface of Venus by using synthetic-aperture radar and to measure the planetary gravitational field.
