Rocket Lab says it has closed a $75 million Series D financing round for production of its low-cost Electron rocket, which is expected to see its maiden launch within the next couple of months. The round was led by Data Collective, with additional new funding from Promus Ventures and an undisclosed investor, plus fresh funding from Khosla Ventures, Bessemer Venture Partners and K1W1. Rocket Lab, now headquartered in Huntington Beach, Calif., has received $148 million in funding to date for a valuation in excess of $1 billion. That qualifies the company as a “unicorn,” in tech parlance.
