Three New Views of Mars' Moon Phobos

Taken with the infrared camera on NASA's Odyssey orbiter, the images reveal temperature variations aboard the small moon as it drifts into and out of Mars' shadow.

Six views of the Martian moon Phobos captured by NASA's Odyssey orbiter as of March 2020. The orbiter's THEMIS camera is used to measure temperature variations that suggest what kind of material the moon is made of.

Progress on Cruise Motors, Future Wing Sets Stage for All-Electric X-57 Ground Tests

esaero_winginstall2_0.jpg
Engineers at Empirical Systems Aerospace, or ESAero, perform fit checks on the future wing to be used on the final configurations of NASA’s all-electric X-57 Maxwell, at their facility in San Luis Obispo, California. Using a “fit check” fuselage, seen here, the team is able to determine the safest and most efficient method of integrating the wing to be used in Mods III and IV of X-57, while the primary fuselage prepares for ground, taxi, and flight tests at NASA’s Armstrong Flight Research Center in Edwards, California.

New 3D Mapping Technique Improves Landslide Hazard Prediction

Landslides cause loss of life and billions of dollars in damage each year. The ability to predict them accurately can reduce both.
