Mars
Mars is the fourth planet from the Sun and the seventh largest in the Solar System. A cold, dusty desert world with a thin atmosphere (mostly CO₂), the planet features extinct volcanoes, deep canyons, polar ice caps, and seasons. Mars has two small moons (Phobos and Deimos), a day just over 24 hours long, and a year lasting about 687 Earth days. It is a prime focus of robotic exploration and studies about past water and habitability.

3D International Space Station

Get out your red-blue glasses and float next to the International Space Station (ISS), planet Earth's largest artificial moon. This breathtaking stereo view was constructed from two separate images (S114-E-7245, S114-E-7246) recorded as the shuttle orbiter Discovery undocked from the ISS on August 6. As seen here, from left to right the ISS structure covers about 27 meters (90 feet). The span from the automated Progress supply ship docked in the foreground to the Destiny module hidden behind the station structure is about 52 meters (171 feet) long, while the full (top to bottom) reach of the solar arrays at the left would cover about 73 meters (240 feet). Resupplied by Discovery, the ISS is currently operated by the two member Expedition 11 crew, Sergei Krikalev and John Phillips. News: Beware the Mars Hoax
