A commercial Cygnus cargo freighter departed the International Space Station (ISS) this morning (Feb. 19) after successfully resuming America’s train of resupply runs absolutely essential to the continued productive functioning of the orbiting science outpost.NASA astronauts Scott Kelly and Tim Kopra commanded the release of the privately developed Orbital ATK “S.S. Deke Slayton II” Cygnus resupply ship from the snares of the stations Canadian-built robotic arm at 7:26 a.m. EST – while the space station was flying approximately 250 miles (400 km) above Bolivia.“Honor to give #Cygnus a hand (or arm) in finalizing its mission this morning. Well done #SSDekeSlayton!” Kelly quickly posted to his social media accounts.The Orbital ATK “S.S. Deke Slayton II” Cygnus craft had arrived at the station on Dec. 9, 2015 after blazing to orbit on Dec. 6 atop a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Air Force Station in Florida on the company’s fourth NASA-contracted commercial station resupply mission dubbed CRS-4.To prepare for today’s release, ground controllers at NASA’s Johnson Space Center first used the station’s 57.7-foot-long (17.6- meter-long) robotic arm, Canadarm2, to unberth Cygnus from its place on the stations Earth-facing port of the Unity module at about 5:38 a.m.Cygnus came loaded with over three tons of critically needed supplies and research experiments as well as Christmas presents for the astronauts and cosmonauts living and working on the massive orbital lab complex during Expeditions 45 and 46.Today’s activities were carried live on NASA TV. This brief NASA video shows a few highlights from Cygnus departure:, Cygnus spent approximately 72 days attached to the station. During that time the crews unloaded all the research gear for experiments in areas such as biology, biotechnology, and physical and Earth science.“All good things must come to an end. —> Read More
