How this Martian moon became the 'Death Star'

Mars' largest moon, Phobos, has captured public imagination and been shrouded in mystery for decades. But numerical simulations recently conducted at Lawrence Livermore National Laboratory (LLNL) have shed some light on the ...

Odyssey's three views of Martian moon Phobos

For the first time, NASA's Mars Odyssey orbiter has caught the Martian moon Phobos during a full moon phase. Each color in this new image represents a temperature range detected by Odyssey's infrared camera, which has been ...

Mars' moon Phobos is slowly falling apart

The long, shallow grooves lining the surface of Phobos are likely early signs of the structural failure that will ultimately destroy this moon of Mars.

Japan announces plans to send probe to Martian moon

Japan's space agency JAXA has announced its intention to send a spacecraft to one of Mar's moons, collect a sample from its surface and then return to Earth to allow for analyzing the sample. If successful, it would be the ...

NASA's Perseverance rover captures video of solar eclipse on Mars

NASA's Perseverance Mars rover has captured dramatic footage of Phobos, Mars' potato-shaped moon, crossing the face of the Sun. These observations can help scientists better understand the moon's orbit and how its gravity ...

NASA orbiter snaps stunning views of Mars horizon

Astronauts often react with awe when they see the curvature of Earth below the International Space Station. Now Mars scientists are getting a taste of what that's like, thanks to NASA's 2001 Mars Odyssey orbiter, which completed ...

Does Mars have rings? Not right now, but maybe one day

As children, we learned about our solar system's planets by certain characteristics—Jupiter is the largest, Saturn has rings, Mercury is closest to the sun. Mars is red, but it's possible that one of our closest neighbors ...

Martian moons have a common ancestor

Mars's two moons, Phobos and Deimos, have puzzled researchers since their discovery in 1877. They are very small: Phobos's diameter of 22 kilometers is 160 times smaller than that of our moon, and Deimos is even smaller, ...
