Live coverage: Ariane 5 blasts off with two Intelsat satellites

The Ariane 5 rocket’s fifth flight of the year launched at 2030 GMT (4:30 p.m. EDT) with the Sky Muster and Arsat 2 communications satellites, designed to deliver broadband Internet to far-flung Australian citizens and broadcast television and networking services to Argentina and nearby countries.

SpaceX intends to cut the price of a Falcon 9 rocket launch by up to 30 percent when flying with reused first stage boosters, an achievement the company still hopes to demonstrate before the end of the year, SpaceX’s president said recently.

A bad input to the Ariane 5 rocket’s guidance system that was missed during pre-launch quality control checks caused the launcher to deviate from its expected flight path and place two commercial communications satellites in the wrong orbit Jan. 25, Arianespace announced Friday.
