Live coverage: Falcon 9 disintegrates after launch

An eight-ton Russian Progress supply ship packed with nearly three tons of food, water and fuel for the International Space Station is ready for liftoff Friday on a vital mission to resume cargo deliveries to the outpost after back-to-back logistics flights fell short.

A massive radio broadcasting satellite for SiriusXM is set for liftoff Friday on top of a Falcon 9 rocket, punctuating a busy week for SpaceX that included the debut of a new-generation cargo ship for the International Space Station and a spectacular atmospheric test flight of a prototype rocket over South Texas.

SpaceX’s next Falcon 9 rocket launch is set for no earlier than May 5, sources said Friday, with a Japanese television broadcasting satellite heading to orbit from Cape Canaveral.
