NASAさんのインスタグラム写真 - (NASAInstagram)「🧭 Explorer, 📸 photographer, ⛰️ geologist, 🧪 chemist... Mars Curiosity does it all!⁣ ⁣ The rover captured images on Oct. 11 for this celebratory #selfie, after its second-ever "wet chemistry" experiment using solvents to help its portable laboratory detect certain carbon-based molecules important to the formation of life, called organic compounds. ⁣ ⁣ 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 individual images in this selfie were taken by the Mars Hand Lens Imager (MAHLI), a camera on the end of the rover's robotic arm. The images are stitched together into a panorama; the robotic arm isn't visible in the parts of the images used in the composite.⁣ ⁣ Image Credit: NASA/JPL-Caltech/MSSS⁣ ⁣ #mars #rover #solarsystem #nasa #chemistry #robots」10月26日 6時00分
