Mars Reconnaissance Orbiter News & Features

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,…

These two radargrams from the SHARAD instrument on NASA's MRO reveal how the spacecraft's new very large roll maneuver produces a stronger signal, providing a clearer picture of the Martian subsurface.

This animation depicts NASA's Mars Reconnaissance Orbiter performing a 120-degree roll that increases the strength of its radar signal by 10 times or more.

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…

NASA's Curiosity rover appears as a dark speck in this view captured on Feb. 28, 2025, by the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter.

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…

Captured by the HiRISE camera on NASA's Mars Reconnaissance Orbiter on March 4, 2021, this impact crater was found in Cerberus Fossae. Scientists matched its appearance on the surface with a quake detected by NASA's InSight lander.

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…

Surrounded by frost, these Martian dunes in Mars' northern hemisphere were captured from above by NASA's Mars Reconnaissance Orbiter using its HiRISE camera on Sept. 8, 2022.

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…
