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 hypersonic engine company lands investment from deep-tech firm

super speed

Hypersonic engine technology company Venus Aerospace announced an investment for an undisclosed amount from deep-tech investment firm America's Frontier Fund (AFF).

Venus plans to use the funds to advance its VDR2 engine, which has the potential to support a commercial flight from Los Angeles to Tokyo in under two hours, according to a statement.

"AFF's investment in Venus Aerospace underscores our focus on supporting American companies that are revolutionizing industries of the future," Jordan Blashek, co-founder and managing partner of AFF, said in a news release. "With recent hypersonic advancements from China and Russia, safeguarding American innovation and securing our industrial base has never been more urgent. Venus Aerospace is poised to redefine hypersonic flight and ensure America's continued leadership in aerospace innovation."

Venus plans to integrate components of its RDRE engine into the advanced VDR2 engine, increasing efficiency with air-augmentation technology capable of 2,000 pounds of thrust. This will allow the VDR2 engine to operate at wider ranges of speeds and altitudes. The company plans to ground-test the VDR2 in 2025.

Venus also plans to make history this year by conducting the first atmospheric flight of its RDRE engine, which has applications in the space and defense industries.

"AFF's commitment to pioneering technological advancements aligns seamlessly with our mission to enhance American competitiveness in hypersonics,” Sassie Duggleby, CEO and co-founder of Venus Aerospace, added in the news release. “Their deep-tech expertise and proven track record in scaling innovative companies will be invaluable as we work to achieve our goals."

Venus Aerospace believes these innovations can “strengthen U.S. leadership in aerospace, defense, and energy innovation."

Venus also aims to use its engine technology to power the Stargazer M4, the world's first Mach 4 reusable commercial aircraft and a prime example of advanced propulsion systems.

The company launched in 2020 and has gained $78.3 million in total investments, according to Pitchbook data.

UH secures $5M in philanthropic gifts to bolster engineering, nursing

major gifts

The University of Houston has received two significant philanthropic gifts to advance innovation and healthcare, the college announced this month.

Manmohan Singh Kalsi and Marie-Luise Schubert Kalsi granted $4 million to UH’s Cullen College of Engineering to support endowed and current funds for graduate fellowships and industry interest in the mechanical and aerospace fields.

The gift is the Department of Mechanical and Aerospace Engineering’s largest donation in years, according to UH, and will establish two endowed professorships to attract and retain leading faculty. It will also create the Kalsi Faculty Research Fund, which aims to take emerging research to the next level.

Additionally, UH says it will also bring industry experts to campus to present and collaborate with students via the forthcoming Kalsi Seminar Series.

Manmohan Kalsi earned both his master’s degree and Ph.D. in mechanical engineering from UH. He went on to found Sugar Land-based Kalsi Engineering in 1978, which pioneered hydrodynamic rotary sealing technology and valve technology for nuclear power plants. In 2014, he established an endowed professorship within Cullen College in honor of the late UH professor Gabriel Fazekas.

"This gift provides a tremendous boost to our department's strategic momentum,” Karolos Grigoriadis, chair of the Department of Mechanical and Aerospace Engineering, said in a news release. “By simultaneously supporting faculty, graduate researchers and collaborative seminars, the Kalsis are strengthening every part of our research enterprise and creating new opportunities for discovery, collaboration and student mentorship.”

Meanwhile, Houston’s The Hamill Foundation also gave a $1 million gift to UH’s Andy and Barbara Gessner College of Nursing. The funds will establish The Hamill Foundation Endowed Professorship in Community Care Nursing, to support a faculty member focused on community-based nursing education, partnerships, research, and outreach to underserved communities in Houston.

Additionally, the funding will go toward efforts to address nurse shortages through the newly established UH Health program. The Hamill Foundation has donated $6 million previously to UH through the years, but the latest $1 million is the largest single investment from the foundation to date.

“The Hamill Foundation continues to help us raise the bar for nursing education and address the nursing shortage,” Kathryn Tart, founding dean and professor at Gessner College and Humana Endowed Dean's Chair in Nursing, said in a news release. “The enduring commitment and generosity of The Hamill Foundation allow us to answer the call and educate generations of competent and caring nursing professionals.”

Both of the recent gifts help fund UH’s $1 billion Can’t Stop Houston: The Centennial Campaign. As of September, the university had raised more than $881 million. UH turns 100 years old in March 2027.
