Venus Aerospace has secured $91 million in Series B funding led by Houston-based venture capital firm Mercury Fund, with additional backing from Lockheed Martin Ventures, MESH, PEAK6, Starboard Star Venture Capital, Green Sands Equity, and other investors. The raise follows the company’s May 2025 milestone: the first successful flight test of a high-thrust rotating detonation rocket engine (RDRE). The funding will push Venus from that demonstration phase toward full-scale production of propulsion systems for defense and space applications. The announcement also comes shortly after Pam Melroy, former NASA Deputy Administrator, joined the company’s board. Venus Aerospace Team. Photo via Venus Aerospace.
