The tentative discovery hints at an habitat where life could potentially thrive.

A big rover makes a big find on Mars. Little rovers have their place in exploration, too.

A single 3.5 billion-year-old rock shows signs of all the conditions life needs to thrive.

If passed, it would be the first standalone NASA authorization since 2017.

From the dangers of radiation to the complications of landing a crewed spacecraft, there are myriad technical challenges facing human exploration of Mars.

NASA and ESA have signed a partnership agreement to get the ExoMars Rosalind Franklin rover down to the surface of Mars, getting the mission back on track after geopolitical factors delayed it.

This week brings updates on the next missions to rove — and maybe even fly — over the surface of Mars.

Twenty years ago, a Planetary Society program sent students to NASA's Jet Propulsion Laboratory to work on the Mars Exploration Rovers program.

The project has the potential to transform our understanding of the Solar System and provide evidence of life beyond Earth.

Though promising conceptually, Starship presents more questions than answers for NASA's Mars Sample Return needs.

Atlas V precisely delivered 29 broadband satellites dedicated to connecting the world

Spacesuit work and eye checks wrapped up the week for the Expedition 74 crew aboard the International Space Station. The orbital residents also focused on robotics, cargo transfers, and science hardware maintenance at the end of the week.

The Expedition 74 crew studied how the brain receives signals in space and demonstrated advanced technology to remove humidity from spacecraft on Thursday. Other activities aboard the International Space Station included servicing a metal 3D printer and continuing to unpack a cargo resupply ship.

Medical tests and microbiology topped the research schedule for the Expedition 74 crew aboard the International Space Station on Tuesday. The seven crewmates also worked on spacesuits, cargo operations, and life support maintenance.
