SpaceX Aims for Key Test of Most Powerful Rocket Yet

The latest version of Falcon 9 could launch in a few days.

The static fire will ensure the readiness of the newly-upgraded Falcon 9 rocket, which boasts more thrust, before company officials move forward with launching precious cargo into space.

"The Falcon 9 rocket remains vertical at Space Launch Complex 40 at Cape Canaveral Air Force Station," a statement posted online today by Orbcomm said. "The teams will continue working towards a static fire today to verify the rocket's readiness and aim towards launching a few days after the static fire is completed."

The upgraded version of the Falcon 9 stands slightly taller at 229.6 feet and has more thrust, meaning it can lift a heavier load into space.

It's unclear if SpaceX will attempt to land its Falcon 9 booster after liftoff, proving the rocket can be reused. The company has made previous attempts that have come close to landing on a floating barge, but have crash-landed or just barely missed the mark.

The ability to reuse rockets is something Musk said would lower costs and help revolutionize space travel.
