NASA will explore two different strategies for fetching Mars rocks collected by the Perseverance rover, and there's a chance these samples contain evidence of alien life.

NASA has arrived at two ways of returning samples collected on Mars to Earth. Now, the agency will test the options to see if the cache can make it back in the 2030s.

NASA sees two paths for saving its beleaguered plan to retrieve materials from the Red Planet but won’t choose between them until 2026

The Mars Sample Return mission has been ranked as the highest priority by planetary scientists, who hope to find signs of ancient life on Mars.

NASA is pitching a cheaper and quicker way of getting rocks and soil back from Mars. Administrator Bill Nelson presented two options on Tuesday, less than two weeks before stepping down as NASA's chief.

The Perseverance rover has been collecting Martian rock samples since 2021, but NASA is still figuring out how to bring them back to Earth.

NASA hopes a revised plan will get Mars samples back to Earth faster and cost less than the agency's original plan.

NASA will analyze and explore two different landing options for its Mars Sample Return program, though it will take almost two years to do so and is expected to announce its decision in late 2026. The agency had to temporarily hit pause on the program after an independent review found that it could cost between $8 billion and $11 billion,

The agency is starting down two different paths toward the samples' return, but only one will bring the red rocks home.
