Space X is planning on launching CRS-13 to the International Space Station from Launch Complex 40 at the Cape Canaveral Air Force station.
On board the cargo spaceship is 4,800 pounds of cargo and material to support science investigations aboard the space station. Not only will the mission deliver the goods it will return results of earlier experience about a month later when it is released from the ISS and splashes down in the Pacific Ocean in about a month.
Launch time: 15:35 UTC / 10:35 EST.
I will have a live feed up 15:20 UTC or 15 minutes before launch.
