A brightly reflective Enceladus appears before Saturn’s rings, while the planet’s larger moon Titan looms in the distance. Jets of water ice and vapor emanating from the south pole of Enceladus, which hint at subsurface sea rich in organics, and liquid hydrocarbons ponding on the surface on the surface of Titan make these two of the most fascinating moons in the Saturnian system. Enceladus (313 miles, or 504 kilometers across) is in the center of the image. Titan (3,200 miles, or 5,150 kilometers across) glows faintly in the background beyond the rings. This view looks toward the anti-Saturn side of Enceladus and the Saturn-facing side of Titan. The northern, sunlit side of the rings is seen from just above the ringplane. The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on March 12, 2012. The view was acquired at a distance of approximately 600,000 miles (1 million kilometers) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 36 degrees. Image scale is 4 miles (6 kilometers) per pixel on Enceladus. Image credit: NASA/JPL-Caltech/Space Science Institute

NASA’s Mars Reconnaissance Orbiter (MRO) has revealed that movement in sand dune fields on the Red Planet occurs on a surprisingly large scale, about the same as in dune fields on Earth.

Space Exploration Technologies (SpaceX) has finished an important evaluation of a prototype Dragon spacecraft designed to carry people into orbit. This key milestone is part of SpaceX’s partnership with NASA under a funded Space Act Agreement to advance the design of crew transportation vehicles. The primary goal of the tests was to determine whether the layout will allow astronauts to maneuver effectively in the vehicle. Several veteran space shuttle astronauts and NASA engineers conducted the evaluation during a pair of two-day-long reviews. On top, from left, are NASA Crew Survival Engineering Team Lead Dustin Gohmert, NASA astronauts Tony Antonelli and Eric Boe, and SpaceX Mission Operations Engineer Laura Crabtree.

The main parachutes deploy for Boeing’s crew capsule during a parachute drop test on May 2, 2012. This is the second successful parachute drop test for its Crew Space Transportation (CST) spacecraft, part of Boeing’s effort to develop commercial crew transportation capabilities that could ferry U.S. astronauts to and from low-Earth orbit and the International Space Station. To accomplish the task, a helicopter lifted the CST-100 crew capsule to about 10,000 feet above the Delmar Dry Lake Bed near Alamo, Nev. A drogue parachute deployment sequence was initiated, followed by deployment of the main parachute. The capsule descended to a smooth ground landing, cushioned by six inflated air bags.
