The SpaceX string of successful launches ended on June 28, but the United Launch Alliance Atlas V string remains perfect after its 55th launch from Pad 41 at Cape Canaveral Air Force Station.
According to Spaceflight Now, it was also the 22nd consecutive Atlas V to launch on its first attempt.
The payload was a Boeing Global Positioning System IIF (2F) satellite, the tenth in twelve scheduled for deployment. GPS satellites are used by the government and civilian companies; if you've used GPS on your smartphone or in your car, it was probably using the government system.
The next ULA launch is scheduled for July 22 at the Cape's Pad 37. The Delta IV will launch a geostationary communications spacecraft for the military.
SpaceX, meanwhile, has yet to announce any official conclusion about the cause of their Falcon 9 loss.
