As expected, NASA announced Wednesday that the first unpiloted test flight of a SpaceX Falcon 9 rocket and a Crew Dragon astronaut ferry ship has slipped from later this month to March 2. The first unpiloted flight of Boeing’s Starliner capsule is now targeted for the April timeframe.

A new era in GPS navigation launched Sunday, when a SpaceX Falcon 9 rocket climbed into orbit with a Lockheed Martin-built satellite designed to beam higher-power positioning, navigation and timing signals around the world, providing military and civilian users with more accurate data that is more resistant to growing jamming threats.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with the SBIRS GEO Flight 3 satellite for U.S. military infrared reconnaissance. Launch is scheduled for Thursday at 7:46 p.m. EST (0046 GMT).
