(ScienceDaily) Far from home: Wayward star cluster is both tiny and distant

Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way's 'suburbs.' It is located where astronomers have never spotted such a small cluster of stars before.

(Space Fellowship) Spacesuit Cleanup Work as Soyuz Crew Preps for Departure

As a pair of astronauts cleans up their spacesuits after completing a set of spacewalks, more nanosatellites were deployed from Japan’s Kibo lab module. The International Space Station also raised its orbit Tuesday morning to set the stage for the upcoming crew departure. Astronauts Barry WiImore and Terry Virts scrubbed the cooling loops inside the spacesuits after their third and final spacewalk on Sunday. They also sampled the water from the loops and talked about their experiences with  [...]

(Discovery News) US Weather Satellite Breaks Apart After Possible Explosion

The 20-year mission of a U.S. military weather satellite came to an abrupt end last month after a power system temperature spike and an apparent explosion.

(Discovery News) Rosetta Spots its own Fuzzy Comet Shadow and a Halo

During the Rosetta's close flyby of comet Comet 67P/Churyumov-Gerasimenko on Feb. 14, the European spacecraft snapped images of the comet's 'belly' revealing a shadow of itself surrounded by a halo.

(ScienceDaily) Pressure is on to find the cause for vision changes in space

The human body is approximately 60 percent fluids. During spaceflight, these fluids shift to the upper body and move across blood vessel and cell membranes differently than they normally do on Earth. One of the goals of the Fluid Shifts investigation, launching to the International Space Station this spring, is to test the relationship between those fluid shifts and a pattern NASA calls visual impairment and intracranial pressure syndrome, or VIIP. It involves changes in vision and the structure of the eyes and indirect signs of increased pressure in the brain, and investigators say more than half of American astronauts have experienced it during long spaceflights.

(Commercial Space Watch) Video: NanoRacks Cubesat Deployment - March 1, 2015

On March 1, 2015 NanoRacks deployed two Planet Labs Flock 1B Doves CubeSats. This comes after repairs were completed on-orbit allowing NanoRacks to start deploying CubeSats again.

(ScienceDaily) Cloudy, with a wisp of liquid rock: Clouds around exoplanets analyzed

Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system, thanks to new research.

(Commercial Space Watch) Celebrate the Centennial of NASA's Predecessor: The NACA

Today marks a special anniversary for the NASA family. It was 100 years ago, on March 3, 1915, when Congress created the National Advisory Committee for Aeronautics (NACA), the organization from which NASA was created in 1958.

(ScienceDaily) New data on the nature of dark matter

Recent research contributes to the effort to determine the nature of dark matter, one of the most important mysteries in physics. As indirect evidence provided by its gravitational effects, dark matter amounts to more than 80% of the universe.

(Space Fellowship) Far From Home: Wayward Cluster Is Both Tiny And Distant

Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way’s “suburbs.” It is located where astronomers have never spotted such a small cluster of stars before. The new star cluster was discovered by Dongwon Kim, a PhD student at the Australian National University (ANU), together with a team of astronomer [...]
