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.

At 7:24 a.m. EDT, NASA astronaut Jonny Kim, with assistance from NASA astronaut Zena Cardman, captured Northrop Grumman’s Cygnus XL spacecraft using the International Space Station’s Canadarm2 robotic arm.

At approximately 7:18 a.m. EDT, NASA astronaut Jonny Kim will capture the spacecraft using the International Space Station’s Canadarm2 robotic arm, and NASA astronaut Zena Cardman will assist. After capture, the spacecraft will be installed on the Unity module’s Earth-facing port for cargo unloading.

NASA and Northrop Grumman are targeting the safe arrival of the company’s Cygnus XL at approximately 7:18 a.m. EDT Thursday, Sept. 18, to the International Space Station.  The Cygnus XL now will conduct a series of burns to bring the spacecraft to the space station for its robotic capture and installation. NASA astronaut Jonny Kim […]

NASA and Northrop Grumman are delaying the arrival of the Cygnus XL to the International Space Station as flight controllers evaluate an alternate burn plan for the resupply spacecraft. The Cygnus XL will not arrive to the space station on Wednesday, Sept. 17, as originally planned, with a new arrival date and time under review.

Expedition 73 awaits over 11,000 pounds of new science and supplies packed inside Northrop Grumman’s Cygnus XL cargo craft and orbiting Earth toward the International Space Station.
