SpaceX to launch today

SpaceX is introducing a Falcon 9 with client Hisdesat’s PAZ satellite on board today, provided weather remains favorable and everything else goes according to plan. The satellite, an imaging and radar instrument with a planned lifespan of five and a half years, will serve Spanish government and commercial needs, and will also work as part of a constellation together with TerraSAR-X and TanDEM-X to be used jointly between Hisdesat and Airbus.

The launch will make use of a first stage booster for the Falcon 9 rocket first used last August during the FORMOSAT-5 mission, and today’s launch will take place at 6:17 AM PST(9:17 AM EST) during an instantaneous launch window. A backup window is scheduled for Thursday, February 22 at the same time should the launch be scrubbed for Wednesday. It’s taking off from Vandenberg Air Force Base in California.

This launch will also carry SpaceX’s first demonstration satellites for its satellite broadband internet service, to be tested ahead of a full-scale constellation launch. It’s also said to be the first launch of the second generation of SpaceX’s fairing, which is designed to be better able to survive launch for re-use on future missions.
