Rocket Lab CEO Peter Beck shared more details on the company’s next launch, which is set to take off from its New Zealand facility on May 15. The Electron vehicle will be carrying satellites from BlackSky, but delivering that payload is only half of the mission: the other half will be recovering the booster stage after an ocean splashdown.

This is the second of three planned booster recovery missions, part of Rocket Lab’s long-term plan to reach reusability for its launch vehicle, an achievement most famously held by its competitor SpaceX. The first recovery mission, dubbed “Return to Sender,” successfully splashed down in the Atlantic in November. While Beck told reporters Tuesday the condition of that booster “was remarkable,” this upcoming mission nevertheless features a number of component and system upgrades aimed at further fortifying the booster.
