Amazon’s race to challenge SpaceX in orbit is getting a helping hand from its chief competitor: SpaceX itself, which will launch the next batch of Amazon’s Project Kuiper internet satellites skyward on Wednesday.

Choosing SpaceX (which already operates Starlink, Kuiper’s main competitor) marks a shift from Amazon’s prior “launch-agnostic” stance. Amazon has contracted three Falcon 9 flights among 83 total launches across ULA, Arianespace, Blue Origin, and SpaceX to meet the schedule locked in by the Federal Communications Commission (FCC).
