WASHINGTON (Sputnik) — Orbital ATK on Sunday launched its Cygnus cargo ship from the Cape Canaveral Air Force Station (CCAFS) in Florida to resupply astronauts at the International Space Station (ISS) after postponing the launch twice over weather conditions, the US National Aeronautics and Space Administration (NASA) said.
The United Launch Alliance (ULA) Atlas V rocket was initially scheduled to take the Cygnus spacecraft to the ISS at 5:55 p. m. EST (22:55 GMT) on Thursday. The launch was then rescheduled for Friday 5:33 p.m. EST (22:33 GMT), but was cancelled again because of poor weather conditions.
The spacecraft is expected to dock with the ISS on Wednesday.
The improvements come after the October 2014 accident, when an Orbital ATK Antares rocker that was to deliver a Cygnus spacecraft to the ISS crashed six seconds after launch. Orbital ATK suspended deliveries to the ISS after the crash.
