Managers have pushed back the next flight of United Launch Alliance’s Delta 4-Heavy rocket from a launch pad in California until no sooner than early December, and the first launch of SpaceX’s Falcon Heavy for the U.S. Air Force has likely been delayed to some time early next year, officials said this week.

A Russian Soyuz rocket thundered to life with a burst of flame and shot away from the Baikonur Cosmodrome in Kazakhstan Wednesday carrying an international crew of three aloft on a six-hour flight to the International Space Station.

Fresh off a series of three complex spacewalks to repair a $2 billion cosmic ray detector, the International Space Station’s crew is set to receive two robotic resupply freighters in the next week after launches from Florida’s Space Coast and the steppes of Kazakhstan.
