SpaceX plans to launch its 19th cargo resupply mission to the International Space Station this afternoon at 12:51 p.m.
Like all resupply missions, the launch window is immediate, meaning that any hold up due to weather problems, or a problem with the rocket itself will scrub the launch for the day. This will be the third trip to the ISS for this particular uncrewed Dragon capsule and the first use of this Falcon 9 first stage. Both will launch from Space Launch Complex 40 at Cape Canaveral Air Force Station.
The first stage booster will make a landing attempt out to sea on the drone ship Of Course I Still Love You. Typically the first stage boosters have enough fuel to return back to the landing pads at the Airforce base, but SpaceX plans to conduct thermal testing on its second stage requiering a long-duration launch profile.
The external payload for this mission is the Japanese Hyperspectral Imager Suite (HISUI) which will provide important Earth data for scientists on the ground.
