Retired Air Force colonel and former NASA astronaut Pamela Melroy, who previously served as deputy administrator of NASA, recently joined the board of directors at Houston-based Venus Aerospace.

Venus Aerospace, a startup founded in 2020, develops rocket engine technology, including rotating rocket detonation engines for hypersonic flights. These engines promise higher power, greater fuel efficiency and lower emissions than conventional rocket engines or jet engines, according to the Interesting Engineering website. The global rocket propulsion market is expected to grow from $9.5 billion in 2025 to $29.9 billion by 2034, according to a forecast by ResearchAndMarkets.com.

“Advanced rocket propulsion has been of interest to me for over a decade, and Venus Aerospace’s recent achievements in demonstrating the stability of rotating detonation rocket engines represent a significant development,” says Melroy, who left NASA earlier this year and is now a self-employed consultant living in Arlington, Virginia.

Melroy, a member of the United States Astronaut Hall of Fame, has built an illustrious career in the aerospace sector. Aside from being a NASA official, she was:

  • One of only two female astronauts to command a space shuttle mission
  • Deputy program manager of Orion space exploration initiatives at aerospace and defense contractor Lockheed Martin
  • Senior technical adviser and director of field operations for the Federal Aviation Administration’s Office of Commercial Space Transportation, where she came up with the first safety guidelines for commercial human spaceflight
  • Deputy director of the Tactical Technology Office at the Defense Advanced Research Projects Agency (DARPA).
  • An adviser for the establishment of the Australian Space Agency

Venus Aerospace said in a news release that as a leader at three federal agencies, “Melroy shaped America’s strategy in space, accelerated commercial space partnerships, and deepened space exploration.”

Sassie Duggleby, co-founder and CEO of Venus Aerospace, called Melroy “a preeminent leader in the world of aerospace.”

In May, Venus Aerospace completed the inaugural test flight of its rotating detonation rocket engine. The startup, whose headquarters is at the Houston Spaceport, says it’s the only company in the world that has manufactured a flight-proven, high-thrust rotating detonation rocket engine.

On the horizon for Venus Aerospace is production of Stargazer M4, a high-speed aircraft capable of two-hour global travel.

Venus Aerospace’s investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. The startup also gets support from the Air Force Research Laboratory (AFWERX), the Air Force, NASA and DARPA.

Jordan Blashek, co-founder and managing partner of America’s Frontier Fund, which backs startups creating breakthrough technologies, said his firm’s investment in Venus Aerospace “underscores our focus on supporting American companies that are revolutionizing industries of the future.”

“With recent hypersonic advancements from China and Russia, safeguarding American innovation and securing our industrial base has never been more urgent,” Blashek added. “Venus Aerospace is poised to redefine hypersonic flight and ensure America’s continued leadership in aerospace innovation.”

Since its founding, Venus Aerospace has raised $78.3 million in investments, according to PitchBook data.

Houston startup with hypersonic engine tech adds new investor

it's rocket science

A Houston-based company that's developing an engine that'll enable one-hour global transportation has announced its latest investor.

Venus Aerospace released the news that Silicon Valley venture capital firm, Airbus Ventures, has joined its team of investors. The supersonic combustion engine technology — more akin to a rocket's engine than an airplane's — is revolutionary because allows for travel at a higher elevation. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally.

“Venus has developed the world’s first liquid-propellant rotating detonation rocket engine (RDRE) with a double-digit percentage increase in efficiency over standard regular engines, making the hypersonic economy possible,” says Sassie Duggleby, CEO and co-founder of Venus, in a news release. “We’re delighted to bring Airbus Ventures into the Venus family and look forward to growing our collaboration as we harness the future of hypersonic flight.”

Duggleby founded Venus Aerospace with her husband and CTO Andrew in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round. That round, led by Prime Movers Lab, is being used to fund tech development and initial flight testing for building its Mach 9 hypersonic drone and Mach 9 spacecraft. Venus did not disclose how much their newest investor has contributed.

“In the world of RDREs, their pioneering approach — designing, building, and demonstrating the first liquid, storable-propellant fueled rotating detonation rocket engine — unlocks advanced aircraft capabilities and opens new vistas on our whole planetary system,” says Airbus Ventures Managing Partner Thomas d’Halluin in the release. “Venus’ compact, low mass, high efficiency engine capability will have an immediate impact on lunar and martian landers, space mobility and logistics, and deep space mission proposals.

"Here on Earth today, we will see unprecedented performance gains for drones of all kinds, and more practical and faster-than-anticipated opportunities for ultra-high-speed passenger and cargo rocket plane flights,” he continues.

Venus, which as has contracts with NASA and US Defense Agencies, has plans to test its technology this summer at its headquarters in the Houston Spaceport.

“With the strong support of Airbus Ventures now joining our investor syndicate, our next round will let Venus take the final step from lab to prototype as we fly our drone to Mach 3 under RDRE power," says Andrew Duggleby, in the release. “This will include long-duration engine runs this summer at Spaceport Houston, as well as the design, build, and flight of our drone with the broader Venus team and our incredible partners.”

Axiom Space launches Japanese subsidiary, names leadership

Axiom Space is setting up a Japanese subsidiary to tap into billions of dollars worth of business opportunities in the vast Asia-Pacific region. The company’s new office in Japan will open July 1.

“For the Asia-Pacific region, an Axiom Space presence in Japan means a long-term, direct path to low-Earth orbit for research, for industry, for astronauts, and a partner committed to building that future together with Japan,” Jonathan Cirtain, president and CEO of Axiom Space, said in a news release.

Asia-Pacific spaceflight leaders include Japan, China, India and South Korea.

Until committing to the Asia-Pacific subsidiary, Axiom focused primarily on the U.S. market for space exploration equipment, technology and services. Axiom is building the successor to the International Space Station (ISS), and it provides human spaceflight services and develops next-generation spacesuits.

Fortune Business Insights estimates the Asia-Pacific market for space technology was valued at $155.3 billion in 2025.

“The region is rapidly expanding due to rapidly expanding government space programs, increasing private sector participation, and rising demand for satellite services across densely populated regions,” says Fortune Business Insights, a market research firm.

The region’s combination of strategic investments, market demand and emerging entrepreneurial systems positions Asia-Pacific “for the fastest growth in the global market,” Fortune Business Insights says.

The market research firm pegs the U.S. market for space technology at $251.8 billion in 2025, making it the world’s largest player in that sector.

Veteran Japanese astronaut Koichi Wakata will lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. The Japanese subsidiary will work with government agencies, research institutions, and industrial partners in Japan to expand hardware development and manufacturing, microgravity research and orbital computing.

Wakata was the Japanese space agency’s first program manager for ISS and the station’s first Japanese commander. He also contributed to the construction of ISS, including the Japanese experiment module Kibo. Wakata retired from the Japanese agency, JAXA, in March 2024.

“Japan intends to remain a leading nation in human space exploration post-ISS, and Japanese industry and academia are ready to play a central role in the commercial era,” Axiom Space said in the release. “Axiom Space Japan is how the company will meet that ambition with a long-term, on-the-ground presence.”
