Houston-based Venus Aerospace successfully completed the first U.S. flight test of its proprietary engine at a demonstration at Spaceport America in New Mexico.

Venus’ next-generation rotating detonation rocket engine (RDRE) is supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA and aims to enable vehicles to travel four to six times the speed of sound from a conventional runway. The recent flight test was the first of an American-developed engine of its kind.

"With this flight test, Venus Aerospace is transforming a decades-old engineering challenge into an operational reality,” Thomas d'Halluin, managing partner at Airbus Ventures, an investor in Venus, said in a news release. “Getting a rotating detonation engine integrated, launch-ready, and validated under real conditions is no small feat. Venus has shown an extraordinary ability to translate deep technical insight into hardware progress, and we're proud to support their bold approach in their attempt to unlock the hypersonic economy and forge the future of propulsion."

Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel. It is designed to be affordable and scalable for defense and commercial systems.

The RDRE is also engineered to work with the company's air-breathing detonation ramjet, the VDR2, which helps enable aircraft to take off from a runway and transition to speeds exceeding Mach 6. Venus plans for full-scale propulsion testing and vehicle integration of this system. Venus’ ultimate goal is to develop a Mach 4 reusable passenger aircraft, known as the Stargazer M4.

"This milestone proves our engine works outside the lab, under real flight conditions," Andrew Duggleby, Venus co-founder and chief technology officer, said in the release. "Rotating detonation has been a long-sought gain in performance. Venus' RDRE solved the last but critical steps to harness the theoretical benefits of pressure gain combustion. We've built an engine that not only runs, but runs reliably and efficiently—and that's what makes it scalable. This is the foundation we need that, combined with a ramjet, completes the system from take-off to sustained hypersonic flight."

The hypersonic market is projected to surpass $12 billion by 2030, according to Venus.

"This is the moment we've been working toward for five years," Sassie Duggleby, CEO and co-founder of Venus Aerospace, added in the release. "We've proven that this technology works—not just in simulations or the lab, but in the air. With this milestone, we're one step closer to making high-speed flight accessible, affordable, and sustainable."

Here's why Texas Republicans think NASA's headquarters should move to Texas in 2028. File photo.

Texas Republicans are pushing to move NASA headquarters to Houston

space city

Two federal lawmakers from Texas are spearheading a campaign to relocate NASA’s headquarters from Washington, D.C., to the Johnson Space Center in Houston’s Clear Lake area. Houston faces competition on this front, though, as lawmakers from two other states are also vying for this NASA prize.

With NASA’s headquarters lease in D.C. set to end in 2028, U.S. Sen. Ted Cruz, a Texas Republican, and U.S. Rep. Brian Babin, a Republican whose congressional district includes the Johnson Space Center, recently wrote a letter to President Trump touting the Houston area as a prime location for NASA’s headquarters.

“A central location among NASA’s centers and the geographical center of the United States, Houston offers the ideal location for NASA to return to its core mission of space exploration and to do so at a substantially lower operating cost than in Washington, D.C.,” the letter states.

Cruz is chairman of the Senate Committee on Commerce, Science, and Transportation; and Babin is chairman of the House Committee on Science, Space, and Technology. Both committees deal with NASA matters. Twenty-five other federal lawmakers from Texas, all Republicans, signed the letter.

In the letter, legislators maintain that shifting NASA’s headquarters to the Houston area makes sense because “a seismic disconnect between NASA’s headquarters and its missions has opened the door to bureaucratic micromanagement and an erosion of [NASA] centers’ interdependence.”

Founded in 1961, the $1.5 billion, 1,620-acre Johnson Space Center hosts NASA’s mission control and astronaut training operations. More than 12,000 employees work at the 100-building complex.

According to the state comptroller, the center generates an annual economic impact of $4.7 billion for Texas, and directly and indirectly supports more than 52,000 public and private jobs.

In pitching the Johnson Space Center for NASA’s HQ, the letter points out that Texas is home to more than 2,000 aerospace, aviation, and defense-related companies. Among them are Elon Musk’s SpaceX, based in the newly established South Texas town of Starbase; Axiom Space and Intuitive Machines, both based in Houston; and Firefly Aerospace, based in the Austin suburb of Cedar Park.

The letter also notes the recent creation of the Texas Space Commission, which promotes innovation in the space and commercial aerospace sectors.

Furthermore, the letter cites Houston-area assets for NASA such as:

  • A strong business environment.
  • A low level of state government regulation.
  • A cost of living that’s half of what it is in the D.C. area.

“Moving the NASA headquarters to Texas will create more jobs, save taxpayer dollars, and reinvigorate America’s space agency,” the letter says.

Last November, NASA said it was hunting for about 375,000 to 525,000 square feet of office space in the D.C. area to house the agency’s headquarters workforce. About 2,500 people work at the agency’s main offices. NASA’s announcement set off a scramble among three states to lure the agency’s headquarters.

Aside from officials in Texas, politicians in Florida and Ohio are pressing NASA to move its headquarters to their states. Florida and Ohio both host major NASA facilities.

NASA might take a different approach, however. “NASA is weighing closing its headquarters and scattering responsibilities among the states, a move that has the potential to dilute its coordination and influence in Washington,” Politico reported in March.

Meanwhile, Congressional Delegate Eleanor Holmes Norton, a Democrat who represents D.C., introduced legislation in March that would prohibit relocating a federal agency’s headquarters (including NASA’s) away from the D.C. area without permission from Congress.

“Moving federal agencies is not about saving taxpayer money and will degrade the vital services provided to all Americans across the country,” Norton said in a news release. “In the 1990s, the Bureau of Land Management moved its wildfire staff out West, only to move them back when Congress demanded briefings on new wildfires.”

space update

Houston-based space tech companies Axiom Space and Intuitive Machines recently shared updates on innovative projects and missions, each set to launch by 2027.

Axiom Space

Axiom Space, developer of the world’s first commercial space station and other space infrastructure, is gearing up to launch two orbital data center nodes to low-earth orbit by the end of 2025.

The Axiom Space nodes will lay the foundation for space-based cloud computing. Axiom says orbital data centers provide cloud-enabled data storage and processing, artificial intelligence, and machine learning directly to satellites, constellations, and other spacecraft in Earth’s orbit. This innovation will reduce reliance on earth-based systems, enhance wireless mesh networks and improve real-time operation of space-borne assets, according to Axiom.

Axiom has been working on the development of orbital data centers since 2022. The two nodes going into space in 2025 will be part of Kepler Communications’ 10-satellite data relay network, which is scheduled to launch by the end of this year. Axiom Space and Kepler Communications have been collaborating since 2023.

Kam Ghaffarian, co-founder, executive chairman, and CEO of Axiom, says his company already has deals in place with buyers of space-based cloud computing services. Orbital data centers “are integral to Axiom Space’s vision of era-defining space infrastructure, unlocking transformational capabilities and economic growth,” he says.

Axiom Space says it will be able to buy additional payloads on Kepler’s network to boost capacity for orbital data centers. The two companies will team up to provide network and orbital data center services to various customers.

Intuitive Machines

Meanwhile, Intuitive Machines, a space exploration, infrastructure and services company, has picked SpaceX’s Falcon 9 rocket to launch its fourth delivery mission to the moon. The launch will include two lunar data relay satellites for NASA.

Intuitive Machines says its fourth lunar delivery mission is scheduled for 2027. The mission will comprise six NASA commercial lunar payloads, including a European Space Agency drill set designed to search for water at the moon’s south pole.

“Lunar surface delivery and data relay satellites are central to our strategy to commercialize the moon,” Intuitive Machines CEO Steve Altemus says.

The first of five lunar data relay satellites will be included in the company’s third delivery mission to the moon. The fourth mission, featuring two more satellites, will be followed by two other satellite-delivery missions.

Outfitted with a new type of aerospace technology, a rocket engine developed by Houston startup Venus Aerospace for hypersonic flights will undergo testing this summer.

Supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA, Venus Aerospace came up with a new design for nozzles — engine parts that help manage power — for its compact rocket engine. Venus Aerospace says the newly configured nozzles have “exceeded expectations” and will be incorporated into Venus’ upcoming ground-based engine testing.

“We’ve already proven our engine outperforms traditional systems on both efficiency and size,” Venus Aerospace CEO Sassie Duggleby says. “The technology we developed with NASA’s support will now be part of our integrated engine platform — bringing us one step closer to proving that efficient, compact, and affordable hypersonic flight can be scaled.”

The engine at the heart of Venus’ flight platform is called a rotating detonation rocket engine (RDRE). Venus says it’s the first U.S. company to make a scalable, affordable, flight-ready RDRE.

Unlike conventional rocket engines, Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel.

“This is just the beginning of what can be achieved with Venus propulsion technology,” says Andrew Duggleby, chief technology officer at Venus, founded in 2020. “We’ve built a compact high-performance system that unlocks speed, range, and agility across aerospace, defense, and many other applications. And we’re confident in its readiness for flight.”

Last fall, the company unveiled a high-speed engine system that enables takeoff, acceleration, and hypersonic cruising — all powered by a single engine. While most high-speed systems require multiple engines to operate at different speeds, Venus’ innovation does away with the cost, weight and complexity of traditional propulsion technology.

Among other applications, the Venus system supports:

  • Spacecraft landers
  • Low-earth-orbit satellites
  • Vehicles that haul space cargo
  • Hypersonic drones and missiles

Intuitive Machines engineer talks STEM, innovation, and second chances

Innovator Interview

Mario Romero is an assembly, integration, and test engineer at the innovative Houston aerospace company Intuitive Machines. He previously served as a Navy SEAL and an EVA Flight Simulator Specialist at NASA.

Intuitive Machines landed its IM-2 mission on the moon last month, before calling an early end of mission. The company reported that its lunar lander was on its side, preventing it from completing the mission as planned.

Still, the IM-2 mission landed closer to the lunar South Pole than any previous lander, according to NASA. And the company still has plenty of innovative projects in the works.

The company secured about $2.5 million from NASA to study challenges related to carrying cargo on the company’s lunar lander and hauling cargo on the moon. The lander will be used for NASA’s Artemis missions to the moon and eventually to Mars.

“Someone has to do it; in fact, the more the merrier,” Romero says on being part of an innovative culture.

“Competition forces innovation, and if I can be selfish for a moment, I think it’s of particular importance for Intuitive Machines because my extremely capable team is more than worthy of having their place stamped in history. We, as a species, have to strive to become a multiplanetary species. Incidentally, part of the trickle-down effect of innovation often leads to spin-off technology that in some way benefits humanity here on Earth.”

Last year, Romero was awarded the key to the city from his hometown of Vineland, New Jersey, and made it a point in his speech to give kids a chance to succeed in the future.

“I am the product of many chances, secondary, tertiary, and more, given to me,” Romero says. “Many of these were admittedly entirely undeserving. I look back now and recognize that those teachers, judges, police, etc. might have all seen something in me that I couldn’t then see in myself. … This is precisely why I often emphasize giving kids multiple chances. Kids are kids, and you can never fully know how you’re inspiring them in the moment, nor how the chances that you give them will affect the trajectory of their lives.”

Texas is expected to represent nearly 10 percent of future STEM opportunities in the nation, and nine of the 20 biggest employers in Texas are STEM-related.

As STEM has become increasingly popular in high schools and at the university level, and the aerospace industry continues to innovate, it is possible that many young future innovators may take the same path a young Romero did.

“I think it’s natural that when new leaps are made in the STEM fields, and in the aerospace realm at large, the youth in general become galvanized by it,” Romero says.

“It’s exciting and reinvigorating to understand that humanity is on the cusp of the next great adventure. As fantastic and essential as this is, I want to emphasize the importance of the arts as well. It has an important place and an important role to play in our evolution, so I personally don’t limit youthful interest to STEM alone. There are fantastic works of art awaiting us, in all their variety, that will come as a result of the efforts and innovation.”

Tom Hanks touches down at Space Center Houston for lunar film premiere

To The Moon

The Artemis Exhibit at Space Center Houston shimmered with star power as nearly 500 insiders gathered for an out-of-this-world affair celebrating the premiere of The Moonwalkers: A Journey with Tom Hanks. The immersive cinematic experience, narrated and co-written by Oscar-winning actor Tom Hanks, offers guests a front-row seat to the triumphs of past lunar missions and a look ahead to NASA’s Artemis era.

The VIP reception brought a celestial twist to the traditional cocktail hour. Guests were served shrimp and oysters, along with potato croquettes paired with peach gastrique, a playful nod to the first vegetable grown in space and the first fruit consumed on the Moon. Espresso martinis featuring Hanks’ coffee brand, Hanx, were shaken and served.

Inside the newly renovated Space Center Theater, a 270-degree projection mapping spectacle brought The Moonwalkers to life. The film weaves rare astronaut interviews with behind-the-scenes glimpses into the upcoming Artemis missions.

Following the screening, a panel discussion brought the experience back to Earth. William T. Harris, Space Center Houston president and CEO, moderated a conversation with Tom Hanks, Apollo 16 moonwalker Charlie Duke, and Artemis II astronauts Victor Glover, Christina Koch, and Reid Wiseman. Together, they explored the film’s themes and what lies ahead as humanity returns to the Moon.

The Moonwalkers: A Journey with Tom Hanks is now on view at Space Center Houston. The immersive show is included in the general admission price. It runs 50 minutes and showings begin on the half hour, starting at 10:30 am.

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

5 ways technology is transforming the workplace for people with disabilities

Guest Column

When Camp For All opened its barrier-free gates more than 30 years ago, our founders believed that design could level the playing field for children and adults with challenging illnesses, disabilities, or special needs. Today, that same philosophy is necessary for workplaces across Greater Houston and beyond; only now the ramps and handrails are digital as much as physical, powered by artificial intelligence (AI) and innovation.

Technology has significantly transformed the workplace for individuals with disabilities, making it easier for them to perform their roles with greater efficiency and independence. Tools such as ergonomic workstations, adaptive keyboards, closed captioning, dictation software, screen magnifiers, and robotics help customize the work environment to accommodate various needs. Additionally, advancements in remote work technology have opened the door to broader employment opportunities, reducing physical barriers to participation in the workforce.

Here are five ways that technology turns “reasonable accommodation” into universal enablement and why every employer should take note.

From closed-captioning to real-time conversation

Ten years ago, businesses relied upon human typists and translators to convert conversations and presentations for those with disabilities. Today, AI speech-to-text engines like Microsoft 365’s Live Captions or Google Workspace’s Meet Transcripts render spoken words into on-screen text across 40-plus languages and dialects in milliseconds. This means deaf and hard-of-hearing employees can follow rapid brainstorming sessions without waiting for a post-meeting transcript.

If you are not already using these tools in your workplace, it is easy to start. Most of these services are free or very low-cost, but produce a high return in employee productivity. Individuals with hearing deficiencies can participate in real-time conversations, give feedback, and bring their unique perspectives to the conversation. These tools also enhance productivity for the larger team by providing all employees with a greater flow of ideas, engagement, and recall.

Voice is the new keyboard

Voice assistants like Siri, Alexa, and Windows Voice Access have matured into integrated tools for everyday life and business. They can now handle paragraph-length dictation, code snippets, and complex spreadsheet commands.

Workers with limited dexterity or sight can participate fully in work tasks, which can level the playing field so everyone can succeed and contribute significantly to the workplace. Additionally, voice-assisted technology can help older employees or employees with differing physical needs continue working longer and retain vital organizational knowledge and expertise, contributing to their team's success.

Readability and writing coaches at scale

The new and highly sensitive AI-powered editors, such as GrammarlyGO and Microsoft Editor, flag jargon, suggest plain-language rewrites, and even adjust tone for cognitive accessibility. This can be a game-changer for neurodivergent professionals, including people with dyslexia or ADHD, as they have to use less brain power decoding dense emails and can get help writing responses in their workplace correspondence.

Again, these free or low-cost tools enable all team members to contribute their unique ideas and perspectives when working together to address workplace challenges, better serve clients, and increase productivity.

Alternative text that captures context

Image-recognition models can now draft alt-text beyond “blue shirt on chair.” Tools like Adobe’s Intelligent Captioning or Meta’s Automatic Alt Text describe emotion, action, and even brand context, giving screen-reader users a richer experience.

Employees with blindness or low vision are more likely to navigate online documents, presentations, and requests independently. These technologies also reduce workloads on marketing teams and help them meet accessibility standards without extensive labor and time.

For businesses that want a varied workforce that brings multiple perspectives, these tools give them a power that hasn’t been harnessed before. If employees living with disabilities have more tools at their disposal, they can, in turn, target specific customers in new ways.

Robots and exoskeletons

Many of us remember The Jetsons cartoon show from the 1960s and how far-fetched their housekeeper robot Rosie seemed then. But now, affordable robots and wearable devices to support employees with spinal cord injuries, chronic pain, and disabilities are helping perform repetitive tasks and reducing strain for everyday work tasks.

These devices may revolutionize unemployment to full-time employment opportunities for many individuals. Devices like ABB’s GoFa and Ottobock’s Paexo can help employers reduce injury claims and retain skilled staff; it’s truly a win-win for employees and employers.


The impact is universal

Eight-foot-wide accessible sidewalks, like the ones we have at Camp For All, help wheelchair users, parents pushing a stroller, and travelers rolling luggage. Similarly, AI captions level the playing field for hearing-impaired colleagues, neurodiverse team members, aging professionals, and every employee skimming a meeting on mute. When we treat accessibility as an innovation driver rather than a compliance checklist, we unleash the potential of productivity, loyalty, and creativity throughout our organizations and companies.

Camp For All sees this throughout the year: when design removes barriers, people discover abilities they never knew they had. Let’s bring that spirit into every Houston boardroom and breakroom — because an inclusive workplace isn’t just the right thing, it’s the smart thing.

Pat Prior Sorrells is president and CEO of Camp For All, a Texas-based nonprofit organization. Located in Burton, Texas, the 206-acre Camp For Allsite was designed with no barriers for children and adults with special needs to experience the joy of camping and nature. Camp For All collaborates with more than 65 nonprofit organizations across the Greater Houston area and beyond to enable thousands of campers and their families to discover life each year. She speaks regularly on the need for inclusive design in public spaces.

CPRIT grants $22M to bring top cancer researchers to Houston

fresh funding

Several prominent cancer researchers are coming to the Houston area thanks to $22 million in grants recently awarded by the Cancer Prevention and Research Institute of Texas (CPRIT).

The biggest CPRIT recruitment grant — $6 million — went to genetics researcher Jean Gautier. Gautier, a professor of genetics and development at Columbia University’s Institute for Cancer Genetics, is joining the University of Texas MD Anderson Cancer Center to continue his research.

The website for Gautier’s lab at Columbia provides this explanation of his research:

“The main objective of our research is to better understand the molecular mechanisms responsible for the maintenance of genome stability. These controls are lost in cancer, which is characterized by genomic instability.”

Aside from his work as a professor, Gautier is co-leader of the Herbert Irving Comprehensive Cancer Center’s Cancer Genomics and Epigenomics Program at Columbia.

Other recipients of CPRIT recruitment grants include:

  • $2 million to recruit Xun Sun from the Scripps Research Institute to the University of Texas Medical Branch at Galveston.
  • $2 million to recruit Mingqi Han from the University of California, Los Angeles to MD Anderson.
  • $2 million to recruit Matthew Jones from Stanford University to MD Anderson.
  • $2 million to recruit Linna An from the University of Washington to Rice University.
  • $2 million to recruit Alissa Greenwald from the Weizmann Institute of Science to MD Anderson.
  • $2 million to recruit Niladri Sinha from Johns Hopkins University to the Baylor College of Medicine.
  • $2 million for Luigi Perelli to stay at MD Anderson so he can be put on a tenure track and set up a research lab.

  • Houston Methodist Research Institute
  • Rice University
  • Texas Southern University
  • University of Houston
  • University of Texas Health Science Center at Houston
  • University of Texas MD Anderson Cancer Center
  • University of Texas Medical Branch at Galveston

In addition, nearly $4.45 million in cancer prevention grants were awarded to one researcher at the University of Texas Medical Branch at Galveston and another at Texas Southern University.

Also, five Houston businesses benefited from CPRIT grants for product development research:

  • Allterum Therapeutics, $2,999,996
  • CTMC, $1,342,178
  • Instapath, $900,000
  • Prana Surgical, $900,000
  • InformAI, $465,188

“Texas is a national leader in the fight against cancer,” said Kristen Pauling Doyle, CPRIT’s CEO. “We can measure the return on investment from CPRIT grants … not only in the economic benefits flowing from increased financial activity and jobs in the state, but more importantly in the cancers avoided, detected early, and treated successfully. Thanks to the Legislature’s vision, this commitment is saving lives.”

Overall, CPRIT approved 61 grants totaling more than $93 million in this recent round of funding.
