At an international workshop this week about where NASA’s next Mars rover should land, most of the information comes from a prolific spacecraft that’s been orbiting Mars since 2006.
Thin, blade-like walls, some as tall as a 16-story building, dominate a previously undocumented network of intersecting ridges on Mars, found in images from NASA’s Mars Reconnaissance Orbiter.
This image of a well-preserved unnamed elliptical crater in Terra Sabaea, is illustrative of the complexity of ejecta deposits forming as a by-product of the impact process that shapes much of the surface of Mars.
From the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon.
Erosion-carved troughs that grow and branch during multiple Martian years may be infant versions of larger features known as Martian “spiders,” which are radially patterned channels found only in the south polar region of Mars.
