A solid-fueled Minotaur 4 rocket lifted off from Wallops Island, Virginia at 9:46 a.m. EDT (1346 GMT) Wednesday. The four-stage rocket, comprised of retired Peacekeeper missile parts, launched on a mission to deliver four classified payloads into orbit for the National Reconnaissance Office.

An Indian Polar Satellite Launch Vehicle blasted off and successfully deployed a military electronic surveillance satellite and 28 nanosatellites for companies in the United States, Lithuania, Spain and Switzerland at two different altitudes Monday, before the rocket’s upper stage began an extended mission as a solar-powered experiment platform in low Earth orbit.

SpaceX’s first Falcon Heavy rocket, made up of two previously-flown Falcon 9 boosters and a beefed up central core stage, made the trip to launch pad 39A at NASA’s Kennedy Space Center in Florida and was raised vertical Thursday for testing ahead of its first liftoff next month.
