Since leaving Earth 18 years ago today, @nasa's Mars Reconnaissance Orbiter has reshaped our understanding of the Red Planet and captured stunning imagery from above. See more highlights from this veteran explorer: http://go.nasa.gov/47pY8rf

Were there multiple points in history where microscopic life could have been at Mars’ Jezero Crater? @NASAPersevere is carrying a core sample from a rock that may record a story of the ancient lake’s watery past. #MarsSampleReturn could bring samples to Earth for closer study.

Check out this patchwork of well-preserved mud cracks that @MarsCuriosity found. They show a history of wet-dry cycles on early Mars, which scientists think could have provided conditions for microscopic life to form. Latest findings: http://go.nasa.gov/3QtgykZ

Happy 11th Landiversary, @MarsCuriosity! #OTD the rover survived its wild ride down to a safe landing on Mars. This mountaineering adventurer continues to explore and is facing its toughest climb yet. Catch up on Curiosity’s journey: http://go.nasa.gov/3KpQrr8

Billions of years ago, a river coursed through the area where @NASAPersevere is now. The rocks it brought in hold stories not only of where they came from, but how they got there. What could they reveal about possible ancient life on Mars? Read more: http://go.nasa.gov/3K5IXJA

Spot the “polar bear!” One rock that @NASAPersevere drilled while #SamplingMars had an odd-shaped crystal inside – a mineral that on Earth is good for preserving signs of ancient life. See why one of this rock’s samples could be fascinating to bring to Earth by #MarsSampleReturn.

Otherworldly (literally!) ✨

Two new ultraviolet views from NASA’s @MAVEN2Mars orbiter help show the movement of water vapor and ozone at Mars. MAVEN’s studies help reveal the planet’s climate history and potential for supporting past life.

Capturing its first rock samples was a big deal for @NASAPersevere – an accomplishment fit for a selfie!
#NASAMars

Back in 2021, @NASAPersevere had been scouting for a few months before finding the rock that would provide the first core samples collected on Mars. Learn what these samples could provide that scientists have never had before:

Meet another of the Mars samples that could be brought to Earth by #MarsSampleReturn. Hear from one of @NASAPersevere’s scientists about “Roubion,” the planned rock core that turned out to be something else entirely!
#NASAMars

This sample is waiting on Mars for possible pickup. See how #MarsSampleReturn could bring samples to Earth for detailed study:

Was there ever life on Mars? 🔴

The samples @NASAPersevere is collecting as part of the #MarsSampleReturn campaign could hold the answer. See why one NASA scientist is especially excited about the samples taken from “Wildcat Ridge.”

Nothing like getting a postcard from a good friend. And there’s no-bot-y quite like @MarsCuriosity. Check out this new, stylized view from Curiosity’s perch on the slopes of Mt. Sharp. 📸

Yogi? Bonanza King? Hogwallow Flats?

How do rocks and other features studied by our Mars rovers like @MarsCuriosity and @NASAPersevere get their sometimes unusual names? One of our mission team members explains:
