Crash test dummies buckled into seats in a cut-out section of a regional jet fuselage to help develop new crashworthiness guidelines for future aircraft designs. We even included baggage in the cargo hold. Learn more: [ Go.nasa.gov Link ]
After an almost two-week search, our OSIRIS-REx spacecraft didn’t see any new Earth Trojans, asteroids that co-orbit the sun with Earth. Although no new Earth-Trojans were discovered, the spacecraft’s camera operated flawlessly. It even demonstrated that it could image objects two magnitudes dimmer than originally expected.

Using the same age-old steps of weaving, this small business is now weaving material that will be sent to Mars! This 3-D woven material will be used on the Orion spacecraft as a thermal protection system, and a shock absorber. Learn more: [ Go.nasa.gov Link ]
This week on International Space Station: SpaceX's Dragan cargo craft splashed this week with more than 5,400 lbs. of cargo and experiments aboard, completing the company's 10th resupply mission. Astronauts aboard the Space Station conducted the first of three planned spacewalks to prepare for the second international docking adapter and more!

Zooming in on Saturn's A ring, our Cassini spacecraft revealed narrow, detailed structures that get even finer as its cameras resolution increases. The particles in the A ring typically range in size from several meters across down to centimeters, making them far too small to see individually here. Learn more: [ Go.nasa.gov Link ]

The many-faced comet…The target of the European Space Agency’s Rosetta mission, Comet 67P, was a very active place during its most recent trip through the inner solar system. From growing fractures, collapsing cliffs and massive rolling boulders, the surface of the comet changed. Take a look: [ Go.nasa.gov Link ]
Permanently shadowed and icy regions on dwarf plant Ceres are signatures of its tilted past. The angle at which Ceres spins as it journeys around the sun varies widely over the course of about 24,500 years, which astronomers consider to be a surprisingly short period of time for such dramatic deviations.

Making its fifth flyby over Jupiter's mysterious cloud tops, our Juno spacecraft will sail above the cloud tops, traveling at a speed of about 129,000 miles per hour (57.8 kilometers per second) relative to the gas-giant planet. Learn more: [ Go.nasa.gov Link ]
Some 60 million light-years away, two galaxies are tearing themselves apart. They are so close that they are being distorted by the gravitational forces between them, and are twisting themselves into the unusual and unique shapes seen here. Details: [ Go.nasa.gov Link ]
Sand dunes are scattered across Mars and one of the larger populations exists in the Southern hemisphere. Here, the steep, sunlit side of the dune, called a slip face, indicates the down-wind side of the dune and direction of its migration. Get the details: [ Go.nasa.gov Link ]
After 6 hours and 34 minutes, today’s spacewalk officially ended at 1:58 p.m. EST. All scheduled tasks, plus one ‘get-ahead’ task was completed. A second spacewalk is scheduled for Thursday, March 30, and a third is now targeted for Thursday, April 6. More: [ Go.nasa.gov Link ]
