Photos: Atlas 5 rocket aims for International Space Station

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday, heading due east over the Atlantic Ocean to deliver the Merah Putih communications satellite into orbit around 32 minutes later.

Worsening weather at Rocket Lab’s New Zealand launch facility forced officials to call off the liftoff of a new commercial satellite booster for the third straight day Tuesday.

A Russian Proton rocket topped with a commercial U.S.-built communications satellite for AsiaSat is standing on a launch pad in Kazakhstan for liftoff Thursday.
