A United Launch Alliance Atlas 5 rocket blasted off from Cape Canaveral at 12:13 p.m. EDT (1613 GMT) Saturday to deploy a new Global Positioning System satellite.
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 4 satellite for U.S. military infrared reconnaissance.
The European-built Solar Orbiter spacecraft was installed on top of its United Launch Alliance Atlas 5 launcher Friday at Cape Canaveral, ready for final charging and checkouts before liftoff Feb. 9 to finally begin a more than $1.5 billion science mission first approved by the European Space Agency nearly 20 years ago.
