Venus Aerospace Opens RDRE Test Stand at Houston Spaceport
Venus Aerospace opened a new propulsion test stand at Houston Spaceport on Sept. 10, 2026, backed by $91M in Series B funding.
Venus Aerospace officially opened a new propulsion test stand at the Houston Spaceport on September 10, 2026, expanding the company’s capacity to test its Rotating Detonation Rocket Engine (RDRE) technology at higher thrust levels and for longer durations.
In a press release, the aerospace company stated the new infrastructure will more closely replicate mission conditions as it scales integrated propulsion systems for defense and space applications. The facility’s opening follows a $91 million Series B financing round closed in July 2026 to accelerate RDRE production.
Scaling RDRE technology
The RDRE architecture utilizes a continuous supersonic detonation wave rotating around a combustion chamber. According to Venus Aerospace, this design is 15 percent more efficient than conventional subsonic combustion rocket engines. The company previously completed the first United States flight test of a high-thrust rotating detonation rocket engine at Spaceport America in New Mexico on May 14, 2025.
To transition the propulsion system from flight demonstration to deployment, the company required expanded physical infrastructure capable of handling sustained engine runs.
“Building and testing propulsion systems at this pace requires the right infrastructure around the technology,” said Sassie Duggleby, CEO and co-founder of Venus Aerospace.
Public and private investment
The expansion at the Houston Spaceport is supported by both private capital and state-level investment. In July 2026, Venus Aerospace secured $91 million in Series B funding led by Mercury Fund, with participation from Lockheed Martin Ventures and other investors. The capital is specifically earmarked for maturing the flight-proven RDRE into full propulsion systems.
The company also highlighted the role of local and state authorities, including the Texas Space Commission and the Houston Airport System, in facilitating the new test stand.
“We’re grateful to the Texas Space Commission and the State of Texas for investing alongside companies like Venus. Public investment like this helps companies move faster and keeps critical aerospace capability growing here in Texas,” Duggleby stated.
AirPro News analysis
We view the opening of the Houston Spaceport test stand as a critical bottleneck cleared for Venus Aerospace. While the May 2025 flight test proved the fundamental viability of the high-thrust RDRE concept, scaling the technology for defense and commercial space applications requires rigorous, long-duration ground testing. By securing both the $91 million in private equity and the physical footprint to run continuous high-thrust tests, the company is positioning itself to transition from a research and development firm into a primary propulsion supplier. The 15 percent efficiency gain over conventional rocket engines makes the RDRE highly attractive for next-generation defense platforms and launch vehicles, provided the manufacturing and integration challenges can be met.
