On Wednesday night  Rocket Lab’s reusability program advanced another step. The company recovered the booster from its Electron launcher for the third time.

Rocket Lab is the only other company besides SpaceX, which has successfully recovered the first-stage booster twice in its history to achieve reusability.

Two BlackSky Earth were sent to geospatial imaging satellites to low Earth orbit. That was part of a rapid five-launch agreement on behalf of BlackSky between Rocket Lab and launch services provider Spaceflight Inc. 

The satellites will join seven others already in orbit, as the geospatial intelligence company’s aims to grow its constellation to 14 satellites by the end of this year.

This mission marks Rocket Lab’s twenty-second Electron launch and the fifth mission this year.
