Update: The launch has been postponed for 24 hours due to upper-level winds.
A SpaceX Falcon 9 rocket is expected to launch from Cape Canaveral Air Force Station at 12:50 p.m. Wednesday. The rocket will ferry a Dragon capsule, stuffed with nearly three tons of supplies, to the International Space Station.
The booster is expected to land roughly 200 miles offshore on an unmanned floating platform. The autonomous landing pad will be towed back to shore later this week to unload its catch.
A weather report from Patrick Air Force Base released at noon on Tuesday states that there’s a 90-percent chance that the weather will be cooperative. Forecasters said their primary concern is windspeed at the launchpad.
Launches to the ISS are instantaneous. The rocket must launch within a small window of time in order to link up with the space station as the observatory flies overhead. A backup launch time has been established for Thursday afternoon at 12:27.
While this is the first flight for this particular booster, the capsule will be making its third journey to the orbiting outpost. The capsule flew previously on the CRS-4 and CRS-11 missions.
