BlackSky Global 4

The fourth and last spacecraft in BlackSky’s initial flock of commercial Earth-imaging microsatellites successfully launched Monday aboard a Rocket Lab Electron rocket with three other payloads, setting the stage for the final assembly and launch of at least 20 more BlackSky orbiting surveillance platforms starting later this year.

Rocket Lab’s next launch from New Zealand in August will carry four small spacecraft into orbit for BlackSky’s Earth-imaging constellation, the U.S. Air Force, and a French startup developing a fleet of maritime surveillance satellites, the company announced Monday.
