SpaceX's first launch of the year from Vandenberg Air Force Base has been delayed again to allow for additional time to perform final checkouts of the upgraded payload.
The liftoff of a Falcon 9 rocket, as part of the Spanish PAZ mission, was pushed to Wednesday, SpaceX announced Saturday afternoon. The launch had been rescheduled for Saturday morning, then pushed back to Sunday. The new launch window will open at 6:17 a.m. Wednesday.
"The Falcon 9 and payload remain healthy," according to a statement from Vandenberg Air Force Base.
The primary mission for the launch is to send the 3,000-pound PAZ satellite into orbit. The satellite was developed by Airbus, a commercial aircraft manufacturer, and HISDESAT, a Spanish government satellite services operator that deals primarily in the areas of defense, security, intelligence and foreign affairs.
PAZ, which is Spanish for “peace,” will carry a radar-imaging payload to collect views of Earth to “address civilian needs with multiple applications,” according to the company's website. It is Spain's first radar satellite.
The satellite is designed for a mission of five and a half years and is set to orbit Earth 15 times per day.
The launch will be the first at the base this year from SpaceX and just the second overall at the base. A Delta IV rocket, provided by United Launch Alliance, blasted off from the base on Jan. 12 carrying a secret payload for the National Reconnaissance Office.
