SpaceX blasts off powerful GPS satellite for US military

TAMPA: A SpaceX rocket on Sunday blasted off a powerful GPS satellite for the US Air Force, marking its 21st and final launch for the year 2018."Three, two, one, zero. Ignition and liftoff," said a SpaceX mission control operator as the white Falcon 9 rocket took off under sunny, blue skies at 8:51 am (1351 GMT) from Cape Canaveral, Florida.The launch sent the Global Positioning System III space vehicle (SV) satellite into space to join the Air Force´s constellation of 31 operational GPS satellites.It promises "three times better accuracy," and an extended, 15-year operational life, said a SpaceX statement.Billions of people worldwide depend on GPS to support financial, transportation, and agricultural infrastructure.SpaceX said the rocket was a "rare, expendable" version of the Falcon 9 since it would not attempt to re-land the booster after launch, needing to reserve all the rocket fuel to propel the satellite to its distant orbit.
