Rover Opportunity wrapping up study of Martian valley

"Marathon Valley," slicing through a large crater's rim on Mars, has provided fruitful research targets for NASA's Opportunity rover since July 2015, but the rover may soon move on.

Mars orbiters reveal seasonal dust storm pattern

After decades of research to discern seasonal patterns in Martian dust storms from images showing the dust, but the clearest pattern appears to be captured by measuring the temperature of the Red Planet's atmosphere.

Sand dunes cover much of this terrain, which has large boulders lying on flat areas between the dunes.

Water on the moon?

Prior to the Apollo missions to the moon, scientists speculated that volatiles - including water - may have accumulated in permanently shaded regions at the poles. Then the Apollo era brought the return of lunar samples, ...

Scientists discover evidence of ice age at martian north pole

Using radar data collected by NASA's Mars Reconnaissance Orbiter, a Southwest Research Institute-led team found evidence of an ice age recorded in the polar deposits of Mars. Ice ages on Mars are driven by processes similar ...

Potential habitats for early life on Mars

Recently discovered evidence of carbonates beneath the surface of Mars points to a warmer and wetter environment in that planet's past. The presence of liquid water could have fostered the emergence of life.

Scientists discover fresh lunar craters

A Southwest Research Institute-led team of scientists discovered two geologically young craters—one 16 million, the other between 75 and 420 million, years old—in the Moon's darkest regions.

Mars rover scientist hopes to find more evidence of liquid water

Although the existence of liquid water on the Red Planet was confirmed by NASA's Mars Reconnaissance Orbiter (MRO) last year, the scientific community is gearing up for a more thorough analysis of the topic that could be ...

The rise and fall of Martian lakes

There is a wealth of evidence, collected over the past few decades, that suggests liquid water was abundant in the early history of Mars – one of our nearest and most studied neighbours. However, the size, evolution and ...
