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.

Texas A&M pilots $59M program for autonomous helicopters to fight wildfires

Autonomous firefighting

Texas A&M University's George H.W. Bush Combat Development Complex will receive $59.8 million to develop a way for autonomous helicopters to fight to wildfires in the state.

The funds appropriated from the Texas legislature will go toward acquiring up to four UH-60 Blackhawk helicopters and developing their autonomous configuration, as well as to facilities, tools and equipment for research, testing and integration of firefighting capabilities over the next two years, according to a release from Texas A&M.

The BCDC was also selected to work with the Defense Advanced Research Projects Agency (DARPA) on its Aircrew Labor In-cockpit Automation System (ALIAS), which works to reduce risks for pilots and aircraft in high-risk missions.

"Working together with Texas, we have an opportunity to use autonomous helicopters to completely change the conversation around wildfires from containing them to extinguishing them,” Stuart Young, DARPA program manager for ALIAS, said in a release from DARPA.

The BCDC program will incorporate DARPA's automation toolkit, known as MATRIX, which has already demonstrated fully autonomous flight capabilities on approximately 20 aircraft platforms. MATRIX, which was developed by California-based Sikorsky Aircraft, was previously tested in proof-of-concept demonstrations of autonomous fire suppression in California and Connecticut earlier this year, according to DARPA.

“I am proud we are working with DARPA in a manner that will benefit Texas, the Department of Defense, and commercial industry,” retired Maj. Gen. Tim Green, director of the BCDC, said in the release. “Wildland firefighting will be the first mission application fully developed to take advantage of over a decade of work by DARPA on its Aircrew Labor In-cockpit Automation System (ALIAS).”

The BDC will test fully automated and semi-automated ALIAS-equipped aircraft on highly complex firefighting tasks. The complex will also work with Texas A&M University–Corpus Christi’s Autonomy Research Institute, the Texas Division of Emergency Management, the Texas A&M Engineering Extension Service, the Texas A&M Forest Service and the Texas A&M Engineering Experiment Station on the project.

John Diem, director of the innovation proving grounds at BCDC, will serve as principal investigator for the project.

“Advancing system capabilities through the last stages of technology maturation, operational testing, and concept development is always hugely exciting and rewarding,” Diem added in the release. “The best part of my career has been seeing systems I tested move into the hands of warfighters. Now, I’m proud to help ensure ALIAS is safe and effective in protecting life and property – and we will do that through realistic and challenging testing.”

teaming up

A team led by the University of Texas at Austin and partnered with Rice University was awarded $840 million to develop “the next generation of high-performing semiconductor microsystems" for the U.S. Department of Defense.

The Defense Advanced Research Projects Agency (DARPA) selected UT’s Texas Institute for Electronics (TIE) semiconductor consortium to establish a national open access R&D and prototyping fabrication facility.

The facility hopes to enable the DOD to create higher performance, lower power, lightweight, and compact defense systems. The technology could apply to radar, satellite imaging, unmanned aerial vehicles, or other systems, and ultimately will assist with national security and global military leadership. As a member of DARPA’s Next Generation Microelectronics Manufacturing (NGMM) team, Rice’s contributions are key.

Executive vice president for research Ramamoorthy Ramesh and the Rice researchers will focus on technologies for improving computing efficiency. In a Rice press release, Ramesh notes the need to enhance “energy-efficient computing” which highlights Rice’s qualifications to contribute to the solution.

New microsystem designs will be enabled by 3D heterogeneous integration (3DHI)semi, which is a semiconductor fabrication technology that integrates diverse materials and components into microsystems via precision assembly technologies.

Kepler Computing, is a member of the NGMM team and utilizes ferroelectrics to develop energy-efficient approaches in computer memory and logic, and was co-founded by Ramesh. Other Rice researchers include:

  • Lane Martin, director of the Rice Advanced Materials Institute
  • Ashok Veeraraghavan, chair of electrical and computer engineering
  • Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering and founding chair of the materials science and nanoengineering department
  • Kaiyuan Yang, associate professor of electrical and computer engineering
  • Guha Balakrishnan, assistant professor of electrical and computer engineering

“Given the rapid growth of machine learning AI applications, there is a pressing need to fundamentally rethink current computing methodologies to advance the next generation of microelectronics,” Ramesh says in a news release. ”Rice University boasts world-class researchers with exceptional expertise in computer and electrical engineering poised to bolster this critical federally funded initiative.”

Overall, the project represents a total investment of $1.4 billion. The $840 million award from DARPA is a return on the Texas Legislature’s $552 million investment in TIE. TIE has funded the update of two UT fabrication facilities.

“TIE is tapping into the semiconductor talent available in Texas and nationally to build an outstanding team of semiconductor technologists and executives that can create this national center of excellence in 3DHI microsystems,” S.V. Sreenivasan, TIE founder and chief technology officer and UT professor of mechanical engineering adds.

Houston space tech startup reports milestone achievement in partnership with federal agency

taking flight

A Houston tech company working on an engine to enable hypersonic flights has reported its latest milestone.

Venus Aerospace announced that it's successfully ran the first long-duration engine test of their Rotating Detonation Rocket Engine in partnership with Defense Advanced Research Projects Agency, or DARPA.

The RDRE engine Venus is working on is uniquely designed and a first in the field. It has an additional 15 percent efficiency over traditional rocket engines.

"As we continue to push towards our ultimate mission of high-speed global flight, this is an important technical milestone for having a flight-ready engine," Andrew Duggleby, CTO and co-founder of Venus Aerospace, says in the news release. "I'm incredibly proud of our team as they continue to push forward on this world-changing technology."

The test results are a big win, as the RDRE had previously only been tested in a short-duration capacity. DARPA is just one of several U.S. Government agencies that has contracts with Venus.

"The successful test is a testament to our team's dedication and expertise. We're building something special here at Venus, in large part because we have the right people and the right partners," Sassie Duggleby, CEO and co-founder of Venus Aerospace, adds. "I can't say enough about our collaboration with DARPA and the role they played in helping us make this leap forward."

Last summer, Venus added a new investor to its cap table. Andrew Duggleby founded Venus Aerospace with his wife and CEO Sassie in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round. Sassie joined the Houston Innovators Podcast a year ago to explain her company's mission of "home for dinner."

Rice University develops 2 new innovative tools to detect COVID-19

pandemic tech

Rice University is once again spearheading research and solutions in the ongoing battle with COVID-19. The university announced two developing innovations: a "real-time sensor" to detect the virus and a cellphone tool that can detect the disease in less than an hour.

Sensing COVID
Researchers at Rice received funding for up to $1 million to develop the real-time sensor that promises to detect minute amounts of the airborne virus.

Teams at Rice and the University of Texas Medical Branch (UTMB) at Galveston are working to develop a thin film electronic device that senses as few as eight SARS-CoV-2 viruses in 10 minutes of sampling air flowing at 8 liters per minute, per a press release.

Dubbed the Real-Time Amperometric Platform Using Molecular Imprinting for Selective Detection of SARS-CoV-2 (or, RAPID), the project has been funded by the Defense Advanced Research Projects Agency (DARPA), Rice notes. Further funding will be contingent upon a successful demonstration of the technology.

Attacking with an app
Meanwhile, the university announced that its engineers have developed a plug-in tool that can diagnose COVID-19 in around 55 minutes. The tool utilizes programmed magnetic nanobeads and a tool that plugs into a basic cellphone.

First, a stamp-sized microfluidic chip measures the concentration of SARS-CoV-2 nucleocapsid protein in blood serum from a standard finger prick.

Then, nanobeads bind to SARS-CoV-2 N protein, a biomarker for COVID-19, in the chip and transport it to an electrochemical sensor that detects minute amounts of the biomarker. Paired with a Google Pixel 2 phone and a plug-in tool, researchers quickly secured a positive diagnosis.

This, researchers argue, simplifies sample handling compared to swab-based PCR tests that must be analyzed in a laboratory.

"What's great about this device is that it doesn't require a laboratory," said Rice engineer Peter Lillehoj in a statement. "You can perform the entire test and generate the results at the collection site, health clinic or even a pharmacy. The entire system is easily transportable and easy to use."

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
