The latest commercial resupply mission to the International Space Station is scheduled to launch today at 4:10 p.m. from Cape Canaveral, Florida, where all eyes will again be on the weather the closer we get to liftoff. The forecast improved this morning to a 60 percent chance of acceptable conditions at launch time. Air Force meteorologists will be watching for storms or thick clouds moving close to the launch site.
Our continuous countdown coverage will begin at 3 p.m. here on NASA’s Launch Blog and on NASA TV. A SpaceX Falcon 9 v1.1 rocket topped with a Dragon spacecraft also built by SpaceX remains poised for space following yesterday’s weather-induced scrub.
The uncrewed Dragon will be making the sixth operational cargo delivery mission to the orbiting laboratory and is stocked with 4,300 pounds of material including items for 40 experiments to be performed off the Earth for the benefit of those on the Earth and to study the effects on astronauts of long-duration spaceflight akin to what they’d face on a journey to Mars.
