Rocket Lab is getting ready to fly its tenth mission, delayed from its first launch window last week and now making its second attempt. Aside from being a milestone 10th mission (dubbed ‘Running Out of Fingers,’ ha), this will be the first time that Rocket Lab includes technology designed to help it eventually recover and reuse elements of its launch vehicle.

After first designing its Electron launch platform as a fully expendable spacecraft, meaning it could only do one way trips to bring cargo to orbit, Rocket Lab announced that it would be moving towards rocket reusability at an event hosted by CEO and founder Peter Beck in August. To make this happen, the company will be developing and testing the tech necessary to recover Electron’s first-stage rocket booster over the course of multiple missions.
