8 Thrilling Martian Postcards to Celebrate NASA Curiosity Mars Rover’s Anniversary

Mars Curiosity Rover Mount Sharp

The NASA rover touched down eight years ago, on August 5, 2012, and will soon be joined by a second rover, Perseverance.

NASA’s Curiosity Mars rover has seen a lot since August 5, 2012, when it first set its wheels inside the 96-mile-wide (154-kilometer-wide) basin of Gale Crater. Its mission: to study whether Mars had the water, chemical building blocks, and energy sources that may have supported microbial life billions of years ago.

Curiosity has since journeyed more than 14 miles (23 kilometers), drilling 26 rock samples and scooping six soil samples along the way as it revealed that ancient Mars was indeed suitable for life. Studying the textures and compositions of ancient rock strata is helping scientists piece together how the Martian climate changed over time, losing its lakes and streams until it became the cold desert it is today.

The Curiosity mission is led by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California, and involves almost 500 scientists from the United States and other countries around the world. Here are eight postcards the rover has sent from Mars. Most of the panoramas were taken by the rover’s Mast Camera, or Mastcam, led by Malin Space Science Systems in San Diego.

Martian Dust Storm Grows Global Curiosity Captures Photos

A Dusty Scientist

Curiosity took this selfie on June 20, 2018 (Sol 2082) as a global dust storm enshrouded Mars, filtering sunlight and obscuring the view. The rover drills rocks to analyze their composition and takes a selfie afterward to capture the landscape each sample was taken from (this one is called “Duluth”). Selfies are created by the Mars Hand Lens Imager (MAHLI) camera on the end of the rover’s robotic arm. If you’re wondering why you can’t see the arm in this photo, read more about how selfies are taken here.

Mount Sharp Towers Above

Look up from Curiosity’s current location, and you’d be met with this dramatic view of Mount Sharp, the 3-mile-tall (5-kilometer-tall) peak that Curiosity is exploring. Composed of 44 individual images stitched together, this portrait was taken by the Mastcam on Oct. 13, 2019 (Sol 2555).

Curiosity will never venture to the upper portion of the mountain; instead, it’s exploring the many layers found lower down. Each has a different story to tell about how Mars, which was once more like Earth (warmer and wetter), changed over time. The rover it will reach the next layer later this year.

“I love this image because it tells two stories – one about the mission and one about Mars,” said Ashwin Vasavada, Curiosity’s project scientist at JPL. “The crater rim and floor where we started at eight years ago peek in from the left, while spread out before us is the future as Curiosity climbs higher on the mountain.”

This image, taken back when NASA’s Curiosity rover was at the base of Mount Sharp on March 24, 2014, indicates the rover’s approximate location as of July 30, 2020 – about 3 1/2 miles away (about 5 1/2 kilometers). Credit: NASA/JPL-Caltech

You Are Here

Shot near Mount Sharp’s base on March 24, 2014 (Sol 580), this panorama shows just how far Curiosity has traveled in a little over six years. The arrow indicates the rover’s location today, about 3 1/2 miles away (about 5 1/2 kilometers).

“I can’t help but also think about the corresponding distance we’ve traveled in our understanding of Mars’ habitable past since the time we took this picture,” said Abigail Fraeman of JPL, Curiosity’s deputy project scientist.

Curiosity Project Scientist Ashwin Vasavada gives a descriptive tour of the Mars rover’s view in Gale Crater. The white-balanced scene looks back over the journey so far.

“I still can’t get over how amazingly clear the skies were when we took this, and how we could see for miles and miles and miles,” Fraeman said of this 2018 panorama, which shows the floor of Gale Crater as seen from higher up the mountain, at a location called Vera Rubin Ridge. “How spectacular would the rim of Gale Crater have looked to an astronaut if they were standing on Mount Sharp that day?”

Spaghetti Western Landscape on Mars

This wide panorama was taken by NASA’s Curiosity Mars rover on Dec. 19, 2019, the 2,620th Martian day, or sol, of the mission. On the righthand foreground is Western Butte; the ridge with a crusty cap in the background is the Greenheugh pediment, which Curiosity ascended in March of 2020. Credit: NASA/JPL-Caltech/MSSS

Martian Spaghetti Western

Parts of the Martian desert resemble the American Southwest. This wide panorama, shot by the Mastcam on Dec. 19, 2019 (Sol 2620), includes 130 images stitched together. In the foreground on the right is “Western Butte”; the slope with a crusty cap in the background is the “Greenheugh Pediment,” which Curiosity ascended in March 2020 for a sneak peek of terrain scientists hope to investigate later in the mission.

Martian Sand Dunes

Two sizes of wind-sculpted ripples are evident in this view of the top surface of a Martian sand dune. Sand dunes and the smaller type of ripples also exist on Earth. The larger ripples — roughly 10 feet (3 meters) apart — are a type not seen on Earth nor previously recognized as a distinct type on Mars. Credit: NASA/JPL-Caltech/MSSS

A Sea of Dunes

This location, part of “Namib Dune,” shows two different-sized ripples that the wind-sculpted in the sand. Curiosity discovered that the larger kind, standing roughly 10 feet (3 meters) apart, are found on Mars only as a result of its thin atmosphere. The panorama was taken on Dec. 13, 2015 (Sol 1192).

Drifting Clouds on Mars

NASA’s Curiosity Mars rover imaged these drifting clouds on May 17, 2019, the 2,410th Martian day, or sol, of the mission, using its black-and-white Navigation Cameras (Navcams). Credit: NASA/JPL-Caltech

Staring at Clouds

Curiosity occasionally studies clouds to learn more about the Martian atmosphere. There is vanishingly little water in the Martian air, which is 1% as dense as Earth’s air, but water-ice clouds do sometimes form. The clouds shown here, which are likely water-ice, were captured about 19 miles (31 kilometers) above the surface on May 17, 2019 (Sol 2410), using the rover’s black-and-white Navigation Cameras.
