Curiosity Rover Measures Intriguing Carbon Signature on Mars

Mars Imaged by Hubble

After analyzing powdered rock samples collected from the surface of Mars by NASA's Curiosity rover, scientists today announced that several of the samples are rich in a type of carbon that on Earth is associated with biological processes.

Possible Hydrated Minerals on the Plains of Terra Sirenum On Mars

This image shows a small light-toned exposure of rock on the plains of Terra Sirenum, in a heavily cratered region of the Southern Hemisphere of Mars.

Widespread Megaripple Activity on Martian North Pole Area

Megaripples, intermediate-scale bedforms caused by the action of the wind, have been studied extensively and thought to be largely inactive relics of past climates, save for a few exceptions.

Streaking In Arabia Terra On Mars

This image shows us great examples of transitioning streaks in Arabia Terra.

Leading Into Isidis Planitia On Mars

This public suggestion wanted to get a closer look at an area in Isidis Planitia that might have been carved out by landslide.

Small Rocks Cause A Pause In Mars Perseverance Sample Collection

On Wednesday, Dec. 29 (sol 306) Perseverance successfully cored and extracted a sample from a Mars rock. Data downlinked after the sampling indicates that coring of the rock the science team nicknamed Issole went smoothly.

Ridges Near Vernal Crater On Mars

In this scene, there is contact between a ridged unit and a presumably underlying non-ridged unit.

Lava of Cerberus Palus On Mars

When our camera is pointed straight down at the surface of Mars, we call this "nadir."

Remnants Of Ancient Rivers On Mars

Billions of years ago, a river flowed across this scene in Mawrth Vallis.

Images Of Tianwen-1 Orbiting Mars

China's National Space Administration has released some stunning imagery taken by the Tianwen-1 orbiter currently in circling Mars.

Perseverance Captures Image of Kodiak

This enhanced-color image of Mars' Jezero Crater was taken by the Mastcam-Z instrument aboard NASA's Perseverance rover on April 18, 2021.

A Layered Butte Near The Martian South Pole

Based on a Context Camera image, the rationale for this observation is to get a closer look at this layered butte.

Dunes And Bedrock On Mars

Sometimes, we acquire an image for the simple reason of getting either more coverage of an area, and/or to complete a mosaic of a particular spot.

Elongated Dunes On Mars

These lovely linear dunes at Meroe Patera identified in Context Camera images that have developed in a sand starved region of the dune field, elongating from behind a cliff.

Wind Carved Rock On Mars

The distinctively fluted surface and elongated hills in this image in Medusae Fossae are caused by wind erosion of a soft fine-grained rock.

Earth And Mars Were Formed From Inner Solar System Material

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit.
