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."

TXSE Group wins SEC approval for Texas Stock Exchange to start in 2026

Trading in Texas

The U.S. Securities and Exchange Commission has given the go-ahead to the Dallas-based Texas Stock Exchange to operate as a national securities exchange, clearing the way for the TXSE to begin trading stocks and exchange-traded products by early 2026.

TXSE is the first fully integrated national securities exchange to receive SEC approval in decades. A release calls it "a milestone decision" that restores competition in America's public markets.

The organization has already laid the groundwork with an exchange platform utilizing the appropriate hardware and software that will function in an evolving trading and regulatory environment.

TXSE, which opened its headquarters in Dallas in spring 2025, will launch trading as well as ETP and corporate listings for companies that meet their standards and are fully transparent. Their goal is to compete with the NYSE and NASDAQ by building up a large roster of newly listed companies.

"Today's approval marks a pivotal moment in our effort to build a world-class exchange rooted in alignment, transparency, and partnership with issuers and investors," says TXSX founder and CEO James H Lee. "Real competition for corporate listings in the United States has finally arrived."

According to the release, TXSE's mission is to reverse a decades-long decline in the number of U.S. public companies by reducing the burden of going and staying public while maintaining high quantitative standards in the industry.

They've already pushed for legislative and legal reforms to strengthen Texas' pro-business environment and establish the state as the premier jurisdiction for corporate headquarters, listings, and exchange operators — working alongside Texas leadership to advocate on behalf of issuers and investors to reform policy.

"As the one and only national securities exchange built and headquartered in Texas, we are proud to have been the catalyst for the development of capital markets in our great state," Lee says.

TXSE's founding investors include financial institutions, retail, and institutional investment organizations, including BlackRock, Citadel Securities, and Charles Schwab, as well as major liquidity providers and corporate executives from across the U.S.

TXSE will be one of three exchanges to join Texas' so-called economic hub Y’all Street, along with the New York Stock Exchange and NASDAQ.

Abbott highlights Texas AI boom, with Houston projects on the horizon

AI investments are booming in Texas, Gov. Greg Abbott says. And Houston is poised to benefit from this surge.

At a recent Texas Economic Development Corp. gathering in the Dallas-Fort Worth area, Abbott said AI projects on the horizon in the Lone Star State would be bigger than the $500 billion multistate Project Stargate, according to the Dallas Business Journal. So far, Stargate includes three AI data centers in Texas.

Stargate, a new partnership among OpenAI, Oracle, Softbank, and the federal government, is building AI infrastructure around the country. The project’s first data center is in Abilene, and the center’s second phase is underway. Once the second phase is finished, the 875-acre site will host eight buildings totaling about 4 million square feet with a power capacity of 1.2 gigawatts. An additional 600 megawatts of capacity might be added later.

On Sept. 23, Stargate announced the development of another five AI data centers in the U.S., including a new facility in Shackelford County, Texas, near Abilene. That facility is likely a roughly $25 billion, 1.4-gigawatt AI data center that Vantage Data Centers is building on a 1,200-acre site in Shackelford County.

Another will be in Milam County, between Waco and Austin. In conjunction with Stargate, OpenAI plans to occupy the more than $3 billion center, which will be situated on a nearly 600-acre site, the Austin Business Journal reported. OpenAI has teamed up with Softbank-backed SB Energy Global to build the facility.

Abbott said several unannounced AI projects in Texas — namely, data centers — will be larger than Stargate.

“Bottom line is ... when you look at diversification, the hottest thing going on right now is artificial intelligence,” Abbott said.

The Houston area almost certainly stands to attract some of the projects teased by the governor.

In Houston, Taiwanese tech manufacturer Foxconn already is investing $450 million to make AI servers at the 100-acre Fairbanks Logistics Park, which Foxconn recently purchased for a reported $142 million. The park features four industrial buildings totaling one million square feet. It appears Foxconn will manufacture the servers for Apple and Nvidia, both of which have announced they’ll open server factories in Houston.

The Foxconn, Apple, and Nvidia initiatives are high-profile examples of Houston’s ascent in the AI economy. A report released in July by the Brookings Institution identified Houston as one of the country’s 28 “star” hubs for AI.

The Greater Houston Partnership says the Houston area is undergoing an "AI-driven data revolution."

“As Houston rapidly evolves into a hub for AI, cloud computing, and data infrastructure, the city is experiencing a surge in data center investments driven by its unique position at the intersection of energy, technology, and innovation,” the partnership says.
