Advances in NASA Imaging Changed How World Sees Mars

Sixty years ago, NASA’s Mariner 4 captured groundbreaking views of the Red Planet, leading to a steady stream of advances in the cameras used to study other worlds. In 1965, NASA’s Mariner 4 mission brought Mars into American living rooms, where TV sets showed fuzzy black-and-white images of a cratered landscape. The spacecraft took 21 […]

NASA Mars Orbiter Learns New Moves After Nearly 20 Years in Space

The Mars Reconnaissance Orbiter is testing a series of large spacecraft rolls that will help it hunt for water. After nearly 20 years of operations, NASA’s Mars Reconnaissance Orbiter (MRO) is on a roll, performing a new maneuver to squeeze even more science out of the busy spacecraft as it circles the Red Planet. Engineers […]

NASA Orbiter Spots Curiosity Rover Making Tracks to Next Science Stop

The image marks what may be the first time one of the agency’s Mars orbiters has captured the rover driving. NASA’s Curiosity Mars rover has never been camera shy, having been seen in selfies and images taken from space. But on Feb. 28 — the 4,466th Martian day, or sol, of the mission — Curiosity […]

NASA’s InSight Finds Marsquakes From Meteoroids Go Deeper Than Expected

With help from AI, scientists discovered a fresh crater made by an impact that shook material as deep as the Red Planet’s mantle. Meteoroids striking Mars produce seismic signals that can reach deeper into the planet than previously known. That’s the finding of a pair of new papers comparing marsquake data collected by NASA’s InSight […]

Geyser Season on Mars

This Oct. 29, 2018, image from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter captures geysers of gas and dust that occur in springtime in the South Polar region of Mars. As the Sun rises higher in the sky, the thick coating of carbon dioxide ice that accumulated over the winter begins to warm and […]

Avalanches, Icy Explosions, and Dunes: NASA Is Tracking New Year on Mars

Instead of a winter wonderland, the Red Planet’s northern hemisphere goes through an active — even explosive — spring thaw. While New Year’s Eve is around the corner here on Earth, Mars scientists are ahead of the game: The Red Planet completed a trip around the Sun on Nov. 12, 2024, prompting a few researchers […]

NASA Mars Orbiter Spots Retired InSight Lander to Study Dust Movement

New images taken from space show how dust on and around InSight is changing over time — information that can help scientists learn more about the Red Planet. NASA’s Mars Reconnaissance Orbiter (MRO) caught a glimpse of the agency’s retired InSight lander recently, documenting the accumulation of dust on the spacecraft’s solar panels. In the […]

10 Things for Mars 10

Scientists from around the world are gathering this week in California to take stock of the state of science from Mars and discuss goals for the next steps in exploration of the Red Planet. In the spirit of Mars 10, formally known as the 10th International Conference on Mars, here are 10 recent significant events […]
