Live coverage: Soyuz launches on 13th flight from French Guiana

United Launch Alliance and Boeing teams worked through the weekend on closeouts of the Starliner crew capsule, inspections and final outfitting of the Atlas 5 rocket. A launch readiness review Tuesday approved the continuation of final preparations for liftoff from Cape Canaveral Friday of the first Starliner spacecraft on an unpiloted test flight to the International Space Station.

A Delta 2 rocket lifted off from California’s Central Coast Saturday after back-to-back scrubbed launch attempts earlier this week. The Delta 2 delivered the JPSS 1 weather satellite to orbit for NOAA.

A new Global Positioning System craft will ride a United Launch Alliance Atlas 5 rocket into orbit next month to replace a satellite that has operated in space for 25 years.
