Launch teams are not currently working any issues that would prevent an on time liftoff of Antares this morning at 07:37 EST (12:37 UTC). #Cygnus #Antares #OA8E @OribtalATK

Anomaly Net getting busy again as the Launch Team discuss a pressure setting on the purge system. Not expected to become an issue. #Antares

And actually there is JUST NOW a constraint. Launch team thinks it's a "poorly written" constraint and not an actual issue for launch. They're discussing on the anomaly net & think they'll easily get a waiver to proceed. #Cygnus #Antares #OA8E @OribtalATK

Just a quick note, @NASA TV is NOT showing a live shot of the pad right now. They are showing sunset from last night. There are not people & a forklift at the pad right now. #Cygnus #Antares #OA8E @OribtalATK

40 minutes until liftoff. The Cygnus spacecraft on this flight is carrying 3,338 kilograms, or 7,359 pounds, of supplies to the International Space Station. This is the fifth flight of the enlarged Cygnus pressurized cargo module from Thales Alenia Spaec, providing 25 percent more interior volume for supplies. The spacecraft measures about 20 feet tall, and the pressurized cargo module has a volume of about 27 cubic meters, or 950 cubic feet.

Here are some statistics on today's launch:

[/li]
• 7th Antares rocket launch
• 2nd launch of the Antares 230 configuration
• 13th orbital launch from the Mid-Atlantic Regional Spaceport
• 9th launch of a Cygnus spacecraft
• 1st orbital launch from Wallops in 2017
• 26th U.S. orbital launch in 2017
• 74th global orbital launch attempt in 2017
