The spacecraft named PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) has a nominal operating life of three years with the amount of fuel to potentially have it last a decade. It’s set to launch onboard a Falcon 9 rocket on Tuesday, Feb. 6.

A Falcon 9 rocket launching an Argentine Earth-observing satellite streaked across the skies of Southern California on Sunday night, then its booster stage returned to Vandenberg Air Force Base for an on-target landing, the first by SpaceX on the West Coast.

In a major shift, NASA is considering using two commercial launchers to send an unpiloted Orion crew capsule and its European-built service module on a test flight around the moon next year, maintaining the lunar test flight’s schedule despite fresh delays in the development of the multibillion-dollar Space Launch System that jeopardize the heavy-lifter’s 2020 inaugural flight, the agency’s administrator said in a congressional hearing Wednesday.
