A Rusty Sunset on Mars
4.08.1997

Spica, Mars, and Eclipsed Moon
16.04.2014

A beautiful, reddened Moon slid through dark skies on April 15, completely immersed in Earth's shadow for well over an hour. It was the year's first total lunar eclipse and was widely enjoyed over the planet's Western Hemisphere.

A Digital Opportunity Rover on Mars
14.12.2005

If you could see one of the robot rovers currently rolling across Mars, what would it look like? To gain this perspective useful in planning explorations, the above synthetic image was produced digitally. Above...

Mars Rocks, Sojourner Rolls
30.10.1999

This sharp color image featuring Mars rock Yogi and the rolling Sojourner robot shows off Yogi's two-toned surface. Yogi appears to be leaning into the prevailing winds causing some to suggest that its color contrast may be caused by the accumulation of rust colored dust on its windward face.

Eclipsed Moon and Mars over Mountains

There is something unusual about this astronomically-oriented photograph. It's not obvious -- it was discovered only during post-processing. It is not the Moon, although capturing the Moon rising during a total lunar eclipse is quite an unusually interesting sight.

APOD: 2025 July 6 Б The Spiral North Pole of Mars
6.07.2025

Why is there a spiral around the North Pole of Mars? Each winter this pole develops a new outer layer about one meter thick composed of carbon dioxide frozen out of the thin Martian atmosphere. This fresh layer is deposited on a water-ice layer that exists year round.

The View toward Husband Hill on Mars
3.07.2006

This Martian vista is only part of one of the greatest panoramic views of Mars that has ever attempted. The expansive mosaic is helping to keep the robotic Spirit rover busy over the energy draining winter in the southern hemisphere of Mars.

Mars: A Canyon's Edge
19.03.1998

High resolution Mars Global Surveyor images were combined with Viking Orbiter color data to produce this stunning, detailed view of a Martian canyon's edge. The area pictured is about 6 miles wide and represents a tiny part of the northern edge of the canyon Valles Marineris, whose total length is about 2,500 miles.

Late Afternoon on Mars
20.12.2019

Shadows grow long near sunset in this wide panoramic view from the Curiosity rover on Mars. Made with Curiosity's navcam, the scene covers about 200 degrees from north through east to south (left to right), stitched together from frames taken by the Mars rover on sol 2616. That's just Earth date December 16.
