Orbital ATK will attempt its first launch of an Antares booster since a launch failure in 2014 [spaceflightnow.com]:
NASA and Orbital ATK officials have set Oct. 13 as the target date for the first Antares launch in nearly two years, giving approval for ground crews to load final cargo into the mission's Cygnus supply carrier heading for the International Space Station. [...] This month's launch campaign is the first for Orbital ATK's Antares booster since a catastrophic launch failure on Oct. 28, 2014, destroyed a Cygnus supply ship loaded with equipment for the space station. The mishap also damaged the Antares launch pad at the Mid-Atlantic Regional Spaceport, a facility owned by the government of Virginia at NASA's Wallops Flight Facility.
The launch could be delayed by Hurricane Matthew.
