Watch a live view of the Falcon 9 rocket on the launch pad

After three frustrating days of weather delays, the United Launch Alliance Atlas 5 rocket blasted off from Cape Canaveral at 4:44 p.m. EST (2144 GMT) today to send Orbital ATK’s commercial Cygnus cargo freighter to the International Space Station.

A Boeing Starliner crew capsule fired off a stand early Monday at White Sands Missile Range in New Mexico on a mile-high test flight to validate the spacecraft’s emergency escape thrusters. Only two of the ship’s three main parachutes deployed on descent, but Boeing officials do not expect any impacts on the planned launch of an unpiloted Starliner demonstration mission to the International Space Station in December.

A Russian Progress resupply and refueling craft launched Monday from the Baikonur Cosmodrome in Kazakhstan, riding a Soyuz booster into orbit on a perfectly-timed departure that set the stage for an on-target docking with the International Space Station less than four hours later.
