Venus & Mars Express

Venus Express has been making the most detailed study of the planet’s thick and complex atmosphere to date. The latest findings highlight the features that make Venus unique in the Solar System and provide fresh clues as to how the planet is - despite everything - a more Earth-like planetary neighbour than one could have imagined.

Venus: Earth’s twin planet?

ESA’s Venus Express has revealed Venus as never before. For the first time, scientists are able to investigate from the top of its atmosphere, down nearly to the surface. They have shown it to be a planet of surprises that may once have been more Earth-like, and still is, to a certain extent.

This HRSC image provides a perspective view of residual water ice on the floor of Vastitas Borealis Crater on Mars.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

At high resolution, terrain in the transition region between bright and dark hemispheres on Saturn's moon Iapetus reveals a spotty appearance reminiscent of a Dalmatian. The bright material on the frozen surface of Iapetus, 1,468 kilometers (912 miles) across, is water ice, and the dark material is likely carbonaceous in composition.
