Photo of the Day How massive can a normal star be? Estimates made from distance, brightness and standard solar models had given one star in the open cluster Pismis 24 over 200 times the mass of our Sun, making it one of the most massive stars known. This star is the brightest object located [...]
Background The NASA Engineering and Safety Center (NESC) has reviewed flight, ground test, and published data on ultraviolet-induced degradation of silicone based thermal control coatings. Analysis has shown, for at least one silicone coating, that bake-out plays an important role in ultraviolet (UV) degradation, indicating that UV interaction with paint volatiles, and not the structural [...]
NASA astronauts Zena Cardman and Jonny Kim practice Canadarm2 robotic arm maneuvers on the Destiny laboratory module’s robotics workstation. Kim commanded the Canadarm2 two days later to capture Northrop Grumman’s Cygnus XL cargo craft with Cardman backing him up as the spacecraft arrived at the International Space Station.NASA Expedition 73 kicked off the week with [...]
