SpaceFlightNow is reporting,
Falcon 9 CRS-4 ISS resupply mission.
Launch Date: Sept. 19, 2014
Window: 0638 GMT, 0238 Local (EDT)
Backup Date: Sept. 20, 2014
Window: 0616 GMT, 0216 Local (EDT)
Only 12 days after AsiaSat 6, a very fast reset.
Windows are T-0 = instantaneous, meaning it has to launch exactly on time or scrub to the backup. Each extra day of delay the window is 22 minutes earlier due to orbital mechanics.
Not yet range confirmed, and there is an Atlas V launch on the 16th. If Atlas V shrubs it may force CRS-4 to go later, maintaining a ~3 day spacing to reset the range.
LiveStream SpaceX channel (and SpaceX.com) coverage usually starts 20-25 minutes before launch. We'll get a more accurate time closer to the launch.
Manifest,
2 urgently needed spacesuit batteries needed for a forthcoming spacewalk. 4 more go up on Soyuz later.
ISS-RapidScat: ISS rapid scatterometer, an ocean winds imager
SSIKLOPS: Space Station Integrated Kinetic Launcher for Orbital Payload Systems.
BD: Bone Densitometer, a test of bone mineralization sensors using 40 mousetronauts as test subjects
Arkyd-3: Planetary Resources (asteroid mining) space telescope testbed
SPINSAT: technology demonstrator for electric solid propellant (ESP) thrusters from Digital Solid State Propulsion (DSSP). Electrically activated solid fuel satellite maneuvering thruster testbed
