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 ...
Global topographic map of Venus, with all probe landings marked (red: returned images; with additional black dot: analyzed samples). 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 European Space Agency has officially adopted two new space missions to ... Scientists hope the mission will answer key questions about Venus, including how the world evolved over time and if ...
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 ...
Venus's atmosphere is rich in primordial noble gases compared to that of Earth. [95] This enrichment indicates an early divergence from Earth in evolution. An unusually large comet impact [96] or accretion of a more massive primary atmosphere from solar nebula [97] have been proposed to explain the enrichment. However, the atmosphere is ...
The ancient Hebrews, like all the ancient peoples of the Near East, believed the sky was a solid dome with the Sun, Moon, planets and stars embedded in it. [4] In biblical cosmology, the firmament is the vast solid dome created by God during his creation of the world to divide the primal sea into upper and lower portions so that the dry land could appear.
Venus, our closest planetary neighbor, is sometimes called Earth's twin based on their similar size and rocky composition. ... Also during the 2030s, the European Space Agency's EnVision orbital ...
