The Curiosity rover has now been exploring the surface of Mars for more than 5000 Martian days! Each day on Mars, or "sol," is about 24.6 hours long. How did Curiosity and its team mark the occasion? By working, of course. 🪏 1/2

We have you loud and clear! 📡 NASA is marking the addition of a powerful new 34-meter antenna to our Deep Space Network. The next-generation antenna will expand the communication and navigation capabilities of missions to the Moon and beyond.

Running up that hill! Today, NASA’s Curiosity rover reached the pinnacle — so far — of its 14-year mission on Mars, when it marked an elevation gain of 1 kilometer in its ongoing journey from Gale Crater up the slope of Mount Sharp. 1/2

In its 14 years on Mars, the Curiosity rover has taken more than 700,000 images, but this one is special – because it was one of the first. Happy landiversary, Curiosity!

NASA is pushing the limits of flight on Mars – by spinning helicopter rotor blades so fast they break the sound barrier. A recent test at @NASAJPL achieved Mach 1.08.

Such a great mission.
And splashdown! America is back in the business of sending astronauts to the Moon and bringing them home safely. Reid, Victor, Christina, and Jeremy did an outstanding job. These talented astronauts inspired the world and represented their space agencies and nations as humanity’s ambassadors to the stars. This was a test mission, the first crewed flight of SLS and Orion, pushing farther into the unforgiving environment of space than ever before, and it carried real risk. They accepted that risk for all we stood to learn and for the exciting missions that follow, as we return to the lunar surface, build a Moon base, and prepare for what comes next. And they were not alone. The entire NASA workforce, our commercial and international partners, and the hopes and dreams of people all over the world were with them. The astronauts know it, and you should too. This mission would not have been possible without you. Congratulations. Artemis II, mission accomplished.

An amazing 7 minutes that ended well. Its been quite a journey with Percy these last 5 years @NASAJPL @SpaceHumanity #mars
TODAY IN SPACE HISTORY: FEBRUARY 18, 2021 - PERSEVERANCE LANDS ON MARS "Seven minutes of terror" – entry at 12,000 mph, blazing heat shield, supersonic parachute, then the sky crane lowers the rover gently to Jezero Crater's ancient lakebed. Touchdown! "We're on Mars!" Jezero: once a watery world, perfect for hunting signs of past life. Perseverance rolls out, deploys Ingenuity (first Mars flight), caches samples for future return. Now in 2026: 1,734+ sols strong, ~40 km driven, AI planning drives, organics & biosignature hints found—still exploring, still inspiring. This bold push reminds us: space shows Earth's fragility & unity—the Overview Effect in action. At Space for Humanity, we're sending citizen astronauts up for that same transformative view—to spark positive change back home. Dare mighty things. One planet, one crew. 🌍✨ Image courtesy of @NASA #TodayInSpaceHistory #Perseverance #MarsLanding #JezeroCrater #OverviewEffect #SpaceForHumanity #CitizenAstronaut #2Space4Earth

Our Perseverance rover has recorded the sounds of electrical sparks and mini-sonic booms in dust devils on Mars. 🌪️⚡️ Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover. Listen in: go.nasa.gov/4ow4612

amazon.com/dp/B0G2LB7YZY/ My first children’s book is out! My JPL colleague Nagin Cox and I wrote it inspired by our friend and colleague Claudia Alexander, a scientist who became the Galileo mission’s project manager. Claudia left us way too soon but she still inspires many.

If you ever doubt your place in the universe, remember this: 11 million of your names are on Mars with me. They’re permanently etched into a microchip on my deck. It’s a quiet reminder that exploration is a team effort.

Some Monday motivation: I snapped this shot of my wheels as I drove over some prickly rocks this past weekend. These wheels have had a rough ride on Mars, but they’re still getting me where I need to go! No matter how rocky the road gets, let’s keep going.

The beginning of my mission… what a vibe. 🫶 This was my first full-color selfie, taken in October 2012. Engineers used this image to monitor my wheel wear and dust buildup after only a few months on Mars. Mount Sharp, which I’m still climbing today, was just on the horizon.

We’re celebrating two milestones for @CanberraDSN! The complex, which operates four radio antennas for our Deep Space Network, recently marked its 60th anniversary. Now, preparations are underway for a fifth dish that will increase the network's capacity. go.nasa.gov/425X0sc

Thanks for visiting, @EuropaClipper! I know a thing or two about searching for suitable conditions for life on other worlds and wish you the best on your quest to understand the habitability of Europa. What an adventure!

The journey continues! Mars is behind us, and the next milestone may surprise you: Earth.
