Venus Aerospace Unveils Breakthrough Rocket Engine with Landmark First Flight

Quick Summary

• Venus aerospace, a Houston-based startup, successfully conducted the first-ever test flight of a rotating detonation rocket engine (RDRE) in the U.S.on May 14, 2025.
• The test launch occurred at Spaceport America in New Mexico, with lift-off at 9:37 a.m. EDT.
• The RDRE uses advanced technology to produce higher pressure and efficiency compared to conventional engines, offering greater thrust with less fuel consumption.
• CEO Sassie Duggleby stated that the milestone demonstrates the feasibility of RDRE under real flight conditions and represents five years of progress work.
• CTO Andrew Duggleby emphasized scalability as key for future applications and hypersonic flight potential beyond laboratory settings.
• Venus plans to integrate RDRE with it’s VDR2 air-breathing detonation ramjet for sustained hypersonic flight at speeds up to Mach 6 without boosters.
• Future steps include full-scale propulsion testing and development of their reusable passenger aircraft Stargazer M4 capable of reaching Mach 4.
