Rocket Lab launched a mystery satellite for a secretive private customer this evening (March 5).
We know that the mission lifts a single satellite, and that the target deployment orbit is 470 kilometers above Earth. Rocket Lab ended the launch webcast before that milestone, however, at the request of the unnamed customer.
Some observers speculates that this customer may be the Virginia company BlackSky, which operates a constellation of sharp-eyed Earth observation satellites.
Rocket Lab has flown many missions for BlackSky to date and recently helped the company build out its new “Gen-3” constellation in low earth orbit.
Today’s launch was the 76th to date for the 59-foot-tall (18-meter-tall) Electron, which provides small satellites dedicated trips to track.
Rocket Lab has also flown seven missions with it HASTEa suborbital version of the Electron designed to help customers test hypersonic technologies, bringing the company’s overall ascent tally to 83.
