How long might a rocky, Mars-like planet be habitable if it were orbiting a red dwarf star? It's a complex question but one that NASA's Mars Atmosphere and Volatile Evolution mission can help answer.
The world's newest island—formed during a volcanic eruption in the remote Pacific three years ago—may offer clues to how life potentially developed on Mars, NASA said Wednesday.
US President Donald Trump directed NASA on Monday to send Americans to the Moon for the first time since 1972, in order to prepare for future trips to Mars.
The U.S. space exploration program should continue to focus on robotic sample recovery and human missions to Mars, says Scott Hubbard, Editor-in-Chief of New Space. He details the benefits and risks of this strategy in an ...
Today Mars has only a thin atmosphere, and its surface is very dry with the possible exception of some localised and temporary water seeps. However, ancient eroded valley networks that were discovered by orbiting spacecraft ...
Planetary scientists from Brown University have proposed a new scenario for the formation of ancient clay minerals on Mars that, if shown to be true, could rewrite the early history of the red planet.
In just a few years, NASA's next Mars rover mission will be flying to the Red Planet.
A team of scientists led by The Open University has discovered evidence of recent glacial meltwater on Mars, despite the widely-held view that the recent climate was too cold for ice to melt.
Dark features on Mars previously considered evidence for subsurface flowing of water are interpreted by new research as granular flows, where grains of sand and dust slip downhill to make dark streaks, rather than the ground ...
These striking features on Mars were caused by the planet's crust stretching apart in response to ancient volcanic activity.
