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."

Houston organizations launch study to explore hydrogen-powered travel

sustainability takes flight

A few major players have teamed up to look into making air travel more sustainable — and it's all happening in Houston.

The Center for Houston’s Future, Airbus, and Houston Airports have signed a memorandum of understanding intended to study the “feasibility of a hydrogen hub at George Bush Intercontinental Airport." The study, which will conclude in March of 2025, will include the participants that will collaborate ways to rethink how their infrastructures could be designed and operated to reduce an overall environmental footprint, and lead to hydrogen-powered aircrafts like the ones Airbus plans to bring to fruition by 2035.

In 2020, Airbus debuted its ZEROe hydrogen-powered aircraft project. The “Hydrogen Hub at Airports'' concept by Airbus unites key airport ecosystem players to develop ways to decarbonize all airport-associated infrastructure with hydrogen. The study will include airport ground transportation, airport heating, end-use in aviation, and possibly ways to supply adjacent customers in transport and local industries.

The use of hydrogen to power future aircraft aims to assist in eliminating aircraft CO2 emissions in the air, and also can help decarbonize air transport on the ground. With Houston being such a large city, and a destination for some many visiting on business, the Houston airports was an easy spot to assign the study.

"Houston’s airports are experiencing tremendous growth, connecting our city to the world like never before,” Jim Szczesniak, the aviation director for the city of Houston, says in a news release. “As we continue to expand and modernize our facilities, participating in this sustainability study is crucial. Continuing to build a sustainable airport system will ensure a healthy future for Houston, attract top talent and businesses, and demonstrate our commitment to being a responsible global citizen.

"This study will provide us with valuable insights to guide our development and position Houston as a global leader in sustainable aviation innovation for generations to come.”

The CHF was a founding organizer of the HyVelocity Hydrogen Hub, which was selected by the U.S. Department of Energy as one of seven hydrogen hubs in the nation, and will work in the Houston area and the Gulf Coast. The HyVelocity Hydrogen Hub is eligible to receive up to $1.2 billion as part of a Bipartisan Infrastructure Law funding to advance domestic hydrogen production.

“The Center for Houston’s Future is pleased to have played a crucial role in bringing together the partners for this study,” Brett Perlman, the center's outgoing CEO and president, adds. “With Houston’s role as the world’s energy capital, our record of energy innovation and desire to lead in the business of low-carbon energy, Houston is the perfect place to develop our airports as North American clean hydrogen pioneers.”

SpaceX to get more than 700 acres of Texas wildlife refuge in land swap

Space News

A federal judge on Monday, September 21, refused to block the Trump administration from giving SpaceX more than 700 acres of wildlife refuge as part of a land swap in Texas, while environmental groups vowed to continue their legal challenge.

U.S. District Judge Fernando Rodriguez Jr. declined the plaintiffs' request for a preliminary injunction to prevent the parcel exchange, saying they failed to prove it would worsen ecological risks to a Gulf Coast region already transformed by billionaire Elon Musk’s rocket operations.

In June, the U.S. Fish and Wildlife Service approved moving forward with the deal with SpaceX, which would surrender 683 acres the company owns in exchange for the federal land in the Lower Rio Grande Valley National Wildlife Refuge. The 103,000-acre refuge spans four counties along the Texas border and is home to animal habitats and historical landmarks.

Maps show the land SpaceX would acquire would be closer to the company's launchpad near the U.S.-Mexico border.

The swap amounts to a gift of public lands to SpaceX, “clearing the way for bulldozers to tear into this wildlife refuge as soon as next week and turn a public treasure into a private payday,” said Laiken Jordahl, a spokesperson with the Center for Biological Diversity, which filed the lawsuit alongside other opponents including tribal groups. Jordahl said Monday that the litigation will continue even as the exchange goes forward.

“This court order is not the final word. These lands hold incredible spiritual, historical and conservation value for the people and wildlife of South Texas. We won’t stop fighting to keep this irreplaceable public wildlife refuge safe from SpaceX bulldozers,” Jordahl said in a statement.

The lawsuit asks the federal court to halt the exchange, which has worried SpaceX opponents in the area who have long criticized the company's expanding footprint over lost access to beaches and concerns over exploding rockets.

The Fish and Wildlife Service didn’t respond to a request for comment on Monday’s decision. Previously, a spokesperson had said the agency does not comment on ongoing litigation.

The agency issued a final environmental assessment report in June that determined the exchange would cause no significant impact to the area. The report said the federal government believed the acquisition would represent a “net conservation benefit” and provide “substantial long-term conservation value and improving landscape-scale habitat connectivity across refuges in South Texas.”

The judge said that the plaintiffs offered “relatively weak” evidence of environmental harm.

“While they rightfully argue that the preservation of wildlife and historical lands furthers the public interest, they present no evidence demonstrating that the Property will suffer aesthetic, environmental, cultural, or historical degradation during the pendency of this lawsuit,” Rodriguez wrote in his ruling.

In addition, the judge said a preliminary injunction would result in modifications to SpaceX’s development plans, “placing additional hardship on the company’s ability to meet milestones and contractual obligations.”

SpaceX did not return an email seeking comment on the judge's ruling.

The space exploration company first broke ground in Texas more than a decade ago and has expanded rapidly, so much that SpaceX employees last year voted to incorporate their own local government called Starbase.

Leading pharmaceutical company Eli Lilly broke ground today, Sept. 21, on its $6.5 billion manufacturing site at Houston's Generation Park.

The 236-acre, state-of-the art factory is expected to come online in 2030 and will manufacture Foundayo, the company's first synthetic oral GLP-1 medication, as well as other advanced therapeutics.

"We are thrilled to break ground on our latest ‘medicines made in America’ site in the great state of Texas," David Ricks, Lilly chair and CEO, said in a prepared statement. "This $6.5 billion investment will help change the game for tens of millions of people suffering from overweight, obesity and its consequences like diabetes. We will make and ship Lilly’s latest products from Texas to people here at home and around the world.”

Houston was up against more than 300 locations in the U.S. for the factory, as part of Lilly’s $50 billion investment in domestic medicine production that has launched 10 manufacturing sites since 2020. Lilly first announced Houston had been selected for the site last September.

As Abbott mentioned, the site is expected to create hundreds of jobs, and will hire engineers, scientists, operations personnel and lab technicians once up and running. It will create 4,000 construction jobs while being built.

In an effort to support workforce development, Lilly also announced a $12.5 million commitment to Houston's San Jacinto College in addition to a $2.5 million charitable donation to the San Jacinto College Foundation. The funding will go toward hands-on training, equipment and facilities to support future technicians, operators, maintenance professionals, and other manufacturing talent, according to Lilly. The charitable donation will fund scholarships for students.

"This relationship will build a strong, sustainable talent pipeline for Lilly while creating meaningful, high-demand career opportunities across our region,” Brenda Hellyer, chancellor of San Jacinto College, said in the release.

"When you invest in a place like Houston, you invest in its people first," Edgardo Hernandez, executive vice president and president of Lilly Manufacturing Operations, added. "This facility will run on the talent of this community, powered by our relationship with San Jacinto College. We're hiring across the greater Houston area to help residents build careers close to home."

Lilly previously said it chose Generation Park, a 4,300-acre, master-planned commercial district near Lake Houston, because of factors such as financial incentives, access to utilities and transportation and the region’s business-friendly environment. Generation Park is home to campuses for San Jacinto College and Lone Star College.

Since Lilly first announced plans for the site, another fellow pharma giant has made plans to move into Generation Park. Bristol Myers Squibb Co. announced last month that it would build a $2.3 billion factory in the district. The site is expected to manufacture small molecule, biologic and antibody-drug conjugates and will also come online around 2030. Read more here.
