An anonymous reader writes: An Atlas V rocket carrying a Cygnus cargo spacecraft to resupply the International Space Station has lifted off from Cape Canaveral. This is the first flight of the Cygnus since the previous spacecraft was destroyed during an Antares rocket explosion in 2014. Ars reports: "Sunday's successful launch was the fourth attempt this week to get CRS Orb-4 into space. Three previous launch attempts—one per day since Thursday—were scrubbed due to foul weather at Cape Canaveral. The CRS-4 Cygnus capsule is currently en route to the ISS, carrying about 7300 pounds (about 3300kg) of food, hardware, and scientific equipment for the Expedition 44 crew on board the ISS (which includes US astronaut Scott Kelly, who is more than halfway through a year-long stay aboard the station)."
