04/09/2015 - Using laboratory instruments typically used to make semiconductor devices, space weathering of airless bodies in the Solar System has been simulated, allowing researchers to better determine the ages of their surfaces, states a new paper by Kimberly R. Kuhlman of the Planetary Science Institute. "'Space weathering' is a catch-all term for what happens to surfaces exposed to the environment of space over time. This includes the micrometeorite impact damage and redeposition, effects of UV radiation, ... (source: - more...)

04/09/2015 - Boeing has officially revealed the name for its CST-100 capsule that will ferry astronauts to and from the International Space Station under NASA’s Commercial Crew Program. The capsule, Starliner, will be built inside a former Space Shuttle Orbiter Processing Facility at the Kennedy Space Center — which was officially unveiled Friday morning. (source: - more...)

02/09/2015 - The trio - including the first Danish citizen ever to fly into space - blasted off in the Soyuz TMA 18M rocket on schedule at 0437 GMT from the same launchpad that Yuri Gagarin used for his historic entry into the cosmos in 1961. "The crew is doing well, everything is in order onboard," relayed mission control at Baikonu ... (source: - more...)

02/09/2015 - United Launch Alliance (ULA) is set to deploy the US Navy’s fourth MUOS satellite Wednesday, with an Atlas V carrying the communications spacecraft into a geostationary transfer orbit. Launch, from Space Launch Complex -41 (SLC-41) at Cape Canaveral Air Force Station, Florida, is expected at 09:59 UTC, the start of a 44-minute window. (source: - more...)

31/08/2015 - The first flight of Orbital ATK’s Enhanced Cygnus resupply craft for the International Space Station is set to launch in December atop an Atlas V rocket. Helping Orbital ATK return to flight operations, the Enhanced Cygnus spacecraft will allow the company to meet their initial CRS cargo up-mass contract with NASA in just four more missions.
