The first reaction from the NASA's Perseverance Mars Rover team when they saw this rock was, "Whoa, what is that? What could have caused that?" Learn all about the rover's 25th rock sample, dubbed Sapphire Canyon, and the clues it offers about possible past life on Mars.

Jezero Crater's rim is a treasure trove of rocks! Since January, ARCHIVED - NASA's Perseverance Mars Rover has collected 3 samples, including a rock that's possibly 3.9 billion years old, one that shows signs of ancient water, and one with markings the team has never seen before. go.nasa.gov/3E3E4kR

Billions of years ago on Mars, Jezero Crater held a lake 22 miles wide. The data and samples I’m gathering today can help scientists learn more about the geologic history of Mars – and may one day tell us if microscopic life ever existed here.

Over 1,500 sols spent on Mars – and the dust still keeps me company🙂 Can you spot the dust devil? These columns of air and dust are common on the Red Planet. Scientists can learn more about Martian weather patterns and dust on the planet by studying these whirling wonders.

Sun Devils are leading space exploration. Arizona State University students and scientists are powering NASA’s Europa Clipper mission, capturing images and searching for signs of habitability on the distant Jupiter moon, Europa. 🛰️🔱 news.asu.edu/20250512-scien…

Important Update: As part of NASA’s effort to streamline communications, this account will be archived in the coming weeks – but don't worry, my mission isn't going anywhere. For continued access to the latest Perseverance news, images, and science, please follow NASA Mars.

Not only could geomagnetism influence what happens on the Earth's surface — the converse could also be true: The structure of the crust could feed back on convection in the Earth's core, affecting the geomagnetic field 🤯 nature.com/articles/d4158…

Introducing ARCHIVED ISS Research! Bringing you the incredible science and research happening on our planet and beyond straight to your X feed. Stay tuned for more. 🌎🚀🌠

What do we know about the newly discovered interstellar comet, A1/ATLAS? This rare visitor from beyond our solar system was discovered this week. It's not a threat to Earth, but it poses a great science opportunity! Learn more: science.nasa.gov/solar-system/c…

Now on Scientific American: 3I/ATLAS, the third known interstellar object to enter our solar system, is full of mysteries. Here's what scientists are trying to learn about it before it boomerangs back to the void. By Jonathan O’Callaghan. scientificamerican.com/article/new-in…

Dear Friends, sharing some news here about my upcoming transition. While I’m sad to be leaving School of Earth and Space Exploration Arizona State University after 19 incredible years, I am excited and honored to have the opportunity to contribute to Scripps Institution of Oceanography UC San Diego in the years to come.

More than 280 NASA employees past and present, including at least 4 astronauts, have signed a declaration of opposition to the many drastic changes that the US administration is working to enact go.nature.com/4kM0W7p

NISAR: Revealing Earth's changing surface 🌏 Launching soon, NISAR will give us a detailed view of how Earth’s land and ice surfaces are shifting over time, helping us understand what’s changing, where, and why. Watch to learn more ⬇️

Launch success! NISAR is in orbit and communicating with NASA and @ISRO teams after launching from India this morning 🚀 The mission will study Earth’s land and ice surfaces, providing critical insight into how our planet changes over time. go.nasa.gov/3U5mf9i

🌊💙 Thanks for everything, Margaret! This week, Margaret Leinen steps down as the eleventh director of Scripps Oceanography, leaving behind a legacy of visionary leadership, support for innovative research, and championing of diversity and collaboration. bit.ly/4nU0dDd

Interstellar comet update ☄️ NASA's fleet of spacecraft has been working to collect data on 3I/ATLAS, only the third object ever confirmed to have come from outside our solar system. Several missions have observed the comet – and others will get a chance soon! Details ⬇️

ICYMI, we shared some big news this week! 🎉 Scripps Institution of Oceanography at UC San Diego is proud to welcome esteemed Earth & planetary scientist Meenakshi Wadhwa as the 12th director of our institution. Hear directly from Dr. Wadhwa in this video: youtu.be/lbFLXM6BBbI?si…
