Mars

NASA's Perseverance Mars rover was treated to a 'googly eye' solar eclipse on Sept. 30 as the planet's moon Phobos passed in front of the sun.

China has moved up its timeline for bringing Mars samples to Earth, aiming to do so as early as 2028 — long before the U.S. is slated to achieve this same ambitious goal.

What is the amount of greenhouse warming required to heat up the cold climes of Mars enough so that trees can grow on the Red Planet?

'Photosynthetic habitable zones' could exist beneath radiation-filtering ice on Mars, offering scientists another region in which to hunt for alien life.

NASA's Curiosity rover has new insights into how Mars might have changed from a potentially habitable, water-rich planet to an absolutely uninhabitable desert.

Scientists know quite a bit about the surface of Mars from robotic missions, but there are still many unexplored geologic features that could tell researchers more about the solar system’s formation.

Europe's Mars Express and Trace Gas Orbiter missions captured a variety of cryptic surface features poking through melting ice across the Red Planet's south pole as spring hit the region.

In response to NASA's plea for help bringing the cost and complexity of its Mars sample-return program, Rocket Lab has won a contract to study a potential solution.

New research suggests that the atmosphere of Mars could have literally "gone to ground" as carbon dioxide was greedily slurped out of the atmosphere and locked away by Red Planet clays.
