Traveling to Mars will involve close quarters for more than two years. Here's how astronauts can deal with the stress of those conditions.

Last week, the Martian moon Phobos passed neatly between Mars and the sun. NASA's Perseverance rover caught the fortuitous eclipse on camera.

The latest photos from NASA's immobile Ingenuity Mars helicopter reveal the extent of the rotor blade damage it sustained on its fateful 72nd flight.

The discovery of an ancient lake bed beneath the Perseverance rover's location on Mars could mean the robotic scout has already scraped up microbial fossils. But we won't know for sure until we fetch the sample.

NASA's Ingeunity helicopter has finally ended its three-year mission on Mars after sustaining irreparable rotor damage on its 72nd flight over the Red Planet. It was only designed to fly five times.

NASA's Curiosity rover spotted a rock formation on Mars that looks just like Star Trek's signature Starfleet symbol.

The Mars Express orbiter has detected enough water ice buried beneath the Red Planet's equator to cover the entire planet in a shallow ocean if melted.
