Saturn's Moon Titan Drifting Away Faster Than Previously Thought
Larger than the planet Mercury, huge moon Titan is seen here as it orbits Saturn. Below Titan are the shadows cast by Saturn's rings. This natural color view was created by combining six images captured by NASA's Cassini spacecraft on May 6, 2012.

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