Countdown Nears: Final Tests

Images acquired Jan. 9, 2022, from the Mars Color Imager instrument on NASA’s Mars Reconnaissance Orbiter were combined to create this view showing the presence of a regional dust storm obscuring t...

This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in September 2016 at "Murray Buttes," and the path planned for reachi...

Artist concept of glacier on Mars.

This "ring trough" or eroded pit crater, is located in the rugged southern highland terrain known as Noachis Terra. The HiRISE image shows the layered, boulder-rich wall rock facing to the northeas...

By analyzing radar images like the one at top of this montage, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

The annotated area of Mars in this illustration holds near-surface water ice that would be easily accessible for astronauts to dig up. The water ice was identified as part of a map using data from ...

This HiRISE image covers the southwest portion of the terraces and floor of Holden Crater situated in southwest Margaritifer Terra.

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 (the start of the line in upper right) to a major waypoint called ...

This artist's animation shows how orbiters over Mars will monitor the landing of NASA's Curiosity rover. (No audio)

An oblique, northward-looking view based on stereo orbital imaging, shows the location of Opportunity on its journey from Cape York to Solander Point when HiRISE took the new color image.

Tracks from the first drives of NASA's Curiosity rover are visible in this image captured by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows the transition between the "Murray Formation," in which layers are poorly expressed and difficult to tra...

This graphic presents Martian atmospheric temperature data as curtains over an image of Mars taken during a regional dust storm. The temperature profiles extend from the surface to about 50 miles u...

This image shows part of the surface of Chryse Planitia, near the mouth of several of the giant outflow channels carved by massive floods. At this location the channel is much too large to be seen ...

This Mars map shows variations in thickness of the planet's crust, the relatively thin surface layer overlying the mantle of the planet. It shows unprecedented detail derived from new mapping of va...

This impact crater has gullies incised into its walls on the north and eastern sides. A couple of gullies on the north wall are unusual because a segment in the middle becomes wider than the upslop...

This image shows dunes near the north pole of Mars. The north pole is surrounded by a vast "sea" of basaltic sand dunes, and the dunes imaged here are similar to barchan dunes that are commonly fo...

A towering dust devil casts a serpentine shadow over the Martian surface in this image acquired by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

This image, acquired on May 15, 2018, by NASA's Mars Reconnaissance Orbiter, shows relatively bright mounds scattered throughout darker and diverse surfaces in Chryse Planitia.

This observation shows a wrinkle ridge in Solis Planum, located in the Thaumasia region of Mars, a high-elevation volcanic plain located south of the Valles Marineris canyon system and east of the ...

This image shows a cross-section of a portion of the north polar ice cap of Mars, derived from data acquired by the Mars Reconnaissance Orbiter's Shallow Radar (SHARAD), one of six instruments on t...

This vertically exaggerated view shows scalloped depressions in a part of Mars where such textures prompted researchers to check for buried ice, using ground-penetrating radar aboard NASA's Mars Re...

This map traces where NASA's Mars rover Curiosity drove between landing at a site subsequently named "Bradbury Landing," and the position reached during the mission's 130th Martian day, or sol, (De...

The white speck is NASA’s Perseverance rover in the “South Séítah” area of Mars’ Jezero Crater.

The material in the upper portion of this image, perhaps hardened volcanic ash deposits, is being eroded into parallel long, thin ridges called yardangs by the strong prevailing winds.
