New research used spots on Earth, including Iceland and Idaho, to study the seasons on ancient Mars.

Researchers may have come up with a solution to one of the most pressing challenges of a Mars voyage: How do we get back?

The most habitable place for life on Mars was probably up to several miles below the surface, a new study shows.

An electrolysis system can pull oxygen and fuel from briny water, just like the H2O on Mars. The tech also opens up oceans as a fuel source here on Earth.

Billions of years ago, Mars was a watery world, not the cold, dry place it is today. A new study partly solves the mystery of where all that water went.

New research turns the theory about where water comes from upside down. It may come out of the planet formation process, researchers say.

Seismologists used data from NASA's InSight Lander to get measurements deep within Mars. What they learned might clarify planetary formation.

Researchers aim to update Apollo-era information about rocket-powered landings on dusty celestial bodies like Mars with new supercomputer simulations.

The chemical reactions that dust storms on Mars cause indicate that our quest to find life on the red planet may need to go beneath the surface.

A new kind of "mini rover" moves in could go places that other wheeled rovers couldn't, such as up a sandy hill.
