A new Russian navigation satellite lifted off Saturday on top of a Soyuz rocket, riding the three-stage booster and a Fregat upper stage into orbit to supplement the country’s Glonass network providing precise global positioning and timing services.

A United Launch Alliance Atlas 5 rocket is set to roll to its launch pad Wednesday at Cape Canaveral, a day before liftoff with a new-generation NOAA weather satellite. The launch of a SpaceX Falcon 9 rocket with a Spanish communications satellite is expected to be shuffled after the Atlas 5 flight in a rapid-fire launch sequence at the Florida spaceport this week.

This is the ascent timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Vandenberg Air Force Base in California with the commercial WorldView 4 Earth-imaging satellite for DigitalGlobe. Launch is scheduled for Friday at 11:30 a.m. local time (2:30 p.m. EDT; 1830 GMT).
