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.

The International Space Station’s three newest crewmembers are getting used to living and working in microgravity. The rest of the Expedition 73 crew assisted the new trio while continuing an array of space biology research and orbital maintenance on Tuesday.

For the first time in International Space Station history, all eight docking ports aboard the orbital outpost are occupied following the reinstallation of Northrop Grumman’s Cygnus XL cargo spacecraft to the Earth-facing port of the station’s Unity module. The eight spacecraft attached to the complex are: two SpaceX Dragons, Cygnus XL, JAXA’s (Japan Aerospace Exploration Agency) HTV-X1, two Roscosmos Soyuz crew spacecraft, and two Progress cargo ships.

Expedition 73 wrapped up the work week At 10:16 a.m. EST, the hatch opened between the International Space Station and the Soyuz MS-28 spacecraft.

NASA’s live hatch opening coverage is underway on NASA+, Amazon Prime, YouTube, and more. Hatch opening is scheduled to begin at 10:10 a.m. EST.

At 7:34 a.m. EST, the Soyuz MS-28 spacecraft docked with the International Space Station’s Rassvet module. NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev launched at 4:27 a.m. (2:27 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan.
