The selfie was taken on Oct. 11, 2019 (Sol 2,553) in a location named "Glen Etive" (pronounced "glen EH-tiv"), which is part of the "clay-bearing unit," a region the team has eagerly awaited reaching since before Curiosity launched. Visible in the left foreground are two holes Curiosity drilled named "Glen Etive 1" (right) and "Glen Etive 2" (left) by the science team. The rover can analyze the chemical composition of rock samples by powderizing them with the drill, then dropping the samples into a portable lab in its belly called Sample Analysis at Mars (SAM).
About 984 feet (300 meters) behind the rover is Vera Rubin Ridge, which Curiosity departed nearly a year ago. Beyond the ridge, you can see the floor of Gale Crater and the crater's northern rim. Curiosity has been ascending Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain inside the crater.
The special chemistry experiment occurred on Sept. 24, 2019, after the rover placed the powderized sample from Glen Etive 2 into SAM. The portable lab contains 74 small cups used for testing samples. Most of the cups function as miniature ovens that heat the samples; SAM then "sniffs" the gases that bake off, looking for chemicals that hold clues about the Martian environment billions of years ago, when the planet was friendlier to microbial life.
But nine of SAM's 74 cups are filled with solvents the rover can use for special "wet chemistry" experiments. These chemicals make it easier for SAM to detect certain carbon-based molecules important to the formation of life, called organic compounds.
