Layered beauty 😍 The Arabia Terra region on Mars has deposits that preserve a record of the planet’s ancient climate. The rhythmic nature of the layers could be due to cyclic processes, such as dust storms, perhaps involving groundwater. 1/2

Two for two! 🙌 After the Viking 1 lander touched down on Mars in July 1976, America logged its second successful Mars landing 50 years ago today when Viking 2 arrived at Utopia Planitia. The lander captured images, analyzed soil, and completed experiments in search of life in this higher-latitude location more than 4000 miles away from Viking 1. 📷 Viking 2's first color image, Sept 5, 1976

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

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

Since going online earlier this month, the new antenna has already relayed data from NASA missions currently exploring Mars, Jupiter, and interstellar space. 🛰️ See which spacecraft are in communication with which Deep Space Network stations ⏤ live: eyes.nasa.gov/apps/dsn-now/d…
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.

On Earth, solar eclipses happen when the Moon passes in front of the Sun as seen from the ground. On Mars, sometimes one of its moons does the same thing…but they’re too small to fully cover the Sun’s disc. Perseverance captured this look at Phobos transiting the Sun in 2024.
