Decelerator (LDSD) — a flying saucer-shaped vehicle that could one day be used to help humans land on Mars — on Saturday (June 28) over the U.S. Navy's Pacific Missile Range in Hawaii.
The flight was designed to test equipment — including a massive 100-foot-wide (30.5 meters) parachute — that could be used to slow a heavy spacecraft as it descends through Mars' atmosphere. During the weekend test, a high-altitude balloon carried the LDSD vehicle to an altitude of 23 miles (37 kilometers), before dropping it. The vehicle's onboard rocket motor fired according to plan, but NASA engineers say the chute inflated but did not deploy correctly.
Still, agency officials say the test flight was a success. "The test vehicle worked beautifully, and we met all of our flight objectives," Mark Adler, project manager for LDSD at NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement. "We have recovered all the vehicle hardware and data records and will be able to apply all of the lessons learned from this information to our future flights."

Early last week, staff members at Kenai Fjords National Park in Alaska received a report of a dog stranded on a cliff ledge near the edge of Exit Glacier. After gaining the dog’s trust, park rangers pulled the dog to safety and carried her out to the trailhead.
Kenai Fjords National Park lies at the edge of Alaska's Kenai Peninsula. It's a land where the ice age lingers and nearly 40 glaciers flow from the Harding Icefield, Kenai Fjords' crowning feature. Wildlife thrives in icy waters and lush forests around this vast expanse of ice.
The area is a tough place to survive, and even tougher if you're a runaway Labradoodle, like Sadie (pictured above). Park rangers say Sadie was at least 20 miles (32 kilometers) from home when she was rescued. Now that she's off the cliffs and back home, the dog is reportedly recovering well, reported the Associated Press. [Related: 8 Amazing National Park Structures]

a slice through the interior of a star that is 55,500 times as massive as the sun.
Some astrophysicists have suggested that supermassive black holes form when hefty stars — those that are more than 10,000 times as massive as the sun — collapse into black holes. Understanding this process could help scientists determine how structures, such as supermassive black holes, formed in the early universe.

Since flamingo chicks have a higher survival rate if they are hand-reared, zookeepers are keeping the babies out of the spotlight for now. When they are older, the birds will join the zoo's flock of flamingoes outside, according to Smithsonian officials. [Related Gallery: World's Cutest Baby Wild Animals] Less «

Indian word meaning "rover of the prairie hen," according to the U.S. Fish & Wildlife Service.
The Seedskadee National Wildlife Refuge spans 43 square miles (111 square kilometers) in southwestern Wyoming. The shrubs and wetlands are located along 36 miles (58 kilometers) of the Green River, which is an important migration route and nesting area for a variety of bird species.
According to the U.S. Fish & Wildlife Service, the refuge lands were once well-traveled trails used by nomadic Indian tribes, fur trappers and early pioneers. [Related: Stunning Images of Lightning] Less «
