By Irene and Klotz CAPE CANAVERAL, Florida (Reuters) – Space Exploration Technologies, also known as SpaceX, plans to try again on Monday to launch its first commercial communications satellite after its Falcon 9 rocket was twice sidelined by technical issues, officials said. Liftoff of the Falcon 9 rocket and a 3.5-ton (3,175 kg) communications satellite owned by Luxembourg-based SES S.A. was targeted for 5:41 p.m. EST (2241 GMT) on Monday from Cape Canaveral Air Force Station in Florida.
