Live coverage: SpaceX’s Falcon 9 rocket makes its final launch of the year

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.

After two successful Falcon Heavy missions in less than 11 weeks, launch fans will likely have to wait until late 2020 for SpaceX’s next Falcon Heavy flight, barring a surprise mission for an unannounced customer.

A European Ariane 5 rocket took off on its first flight of the year Wednesday with a new-generation communications satellite for Intelsat, lighting up the sky over its French Guiana launch base as it arced over the Atlantic Ocean.
