Permanent Link to Delta Rocket Moves to Launchpad for March GPS Launch
The Delta 4 rocket that will launch the next GPS satellite has been rolled out to the launch pad, reports Spaceflight Now. The satellite itself, GPS IIF-9, will be attached to the rocket in March. The United Launch Alliance vehicle is scheduled for launch March 25.
The launch will be the 371st Delta rocket since 1960 and the 29th Delta 4 since 2002. It also marks the 69th GPS satellite launch and the 55th to use a Delta rocket.
