Short article is now out covering our field work in Death Valley National Park and the Mojave Desert earlier this summer! We’re testing new tech and software for future Mars helicopters and aerial vehicles. Photo by me. www.nasa.gov/solar-system... #planetaryscience #nasa #nps #photography

Up up up in elevation, the cold maintains its grasp late into summer, yet here still eventually gives way and thaws.

Hidden in a forested valley carved by glaciers in prehistoric times, the village of Borgund 🇳🇴 retains its epic stave church built circa 1200 C.E. Wooden carvings of stylized dragon heads adorn the gables on the roof, and the wood is darkened by a protective tar.

No AI, this is a real photo taken by Percy’s engineering cameras of astronomical twilight on #Mars! You can see Deimos in the sky too. I worked pretty hard to plan, execute, and analyze this image, and it came out beautifully! A bit noisy, but it was very dark out after all. #astro #planetary

My total eclipse mosaic, taken one year ago today. Totality is a surreal, otherworldly experience. Stunningly beautiful far beyond what even epic photos can show. We are tiny amidst the cosmos, humbly existing in just the right place at just the right time. #eclipse #astro #photography

Happy Blood Worm Moon and Pi Day! Conditions were suboptimal here in Los Angeles, but I was able to snap and manually stack a few decent shots. I love how that red is from the collective light of every sunrise and sunset simultaneously around the world. Makes me feel small yet connected.
