About the Team

The Launch team operates at the intersection of every major aspect of Terran R, from stages and payloads to ground systems, launch, landing, and refurbishment. The Cape is the only place where you see it all come together, offering a level of exposure and responsibility unmatched elsewhere in the program. This is where first flights happen, where history is built on top of history, and where the scale of whats underway is unlike anything in modern aerospace. The mission stays the same, but the work evolves with every milestone : from first launch to reuse, high-cadence operations, and beyond. If youre looking to define whats next in space launch and write a new playbook, not just repeat whats already been done, this is where it happens.
