Cygnus CRS-6
Two years ago, Antares launched from Wallops, Virginia to send supplies to International Space Station. But seconds into the flight, one of it's 2 engines failed and it blew up in a massive fireball. Many thought that reason is, that engines were made in late 60s for Russian N-1, the rocket that was supposed to bring Russians to the Moon, but never succesfully launched (all of the test launches failed and one of them was the most powerful non-nuclear explosion ever. We're getting way off topic so let's get back to Antares. So, it exploded destroying Cygnus spacecraft and next launches needed to be done with ULA's Atlas 5 launch system. But ISS will be getting supplies from Virginia again.
This time launch was delayed for 24h due to a glitch, but it was fixed and Orbital ATK had a spectacular night launch at 7:40 pm 17th October. There were no complications after that and Cygnus is heading to the station now.
