Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace picks up investment from Lockheed Martin Ventures

space funding

Venus Aerospace, a Houston-based startup specializing in next-generation rocket engine propulsion, has received funding from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, for an undisclosed amount. The product lineup at Lockheed Martin includes rockets.

The investment follows Venus’ successful high-thrust test flight of its rotating detonation rocket engine (RDRE) in May. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

Venus says the Lockheed Martin Ventures investment reflects the potential of Venus’ dual-use technology for defense and commercial uses.

“Venus has proven in flight the most efficient rocket engine technology in history,” Venus co-founder and CEO Sassie Duggleby, a board member of the Texas Space Commission, said in a news release. “With support from Lockheed Martin Ventures, we will advance our capabilities to deliver at scale and deploy the engine that will power the next 50 years of defense, space, and commercial high-speed aviation.”

Chris Moran, executive director and general manager of Lockheed Martin Ventures, said Lockheed Martin has been a longtime supporter of early-stage “transformational” technologies.

“Our investment in Venus Aerospace reflects a conviction that next-generation propulsion will define which nations lead in space and defense for decades to come,” Moran added in the release. “We are committed to helping Venus scale this technology and integrate it into critical systems.”

Since its founding in 2020, Venus has secured more than $106 million in funding. In addition to Lockheed Martin Ventures, investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. Supporters of Venus include NASA, the Air Force Research Lab and the Defense Advanced Research Projects Agency (DARPA).

XSpace plans $250M industrial condo expansion with RAFA Racing Club

growth mode

Houston-based XSpace Group has teamed up with two other Houston companies, RAFA Racing Club and Maximo Capital, to develop five industrial condo projects that pair flex space and high-end car storage space with a members-only clubhouse for motorsports enthusiasts.

The five projects will be built in the Dallas-Fort Worth; Miami-Boca Raton; Charlotte-Mooresville, North Carolina; Phoenix-Scottsdale; and Los Angeles markets. Other markets, including Las Vegas, are under consideration for future phases.

XSpace says the initial five-project venture will generate estimated sales of $250 million. Condos will be available to rent or own.

The ground floor of each project will feature a RAFA Racing Club Social & Performance Centre, a members-only clubhouse, event space and lifestyle hub. The remaining floors will offer space for car storage, collectibles, offices and studios. RAFA will operate the ground floor of each building.

“Our goal from day one with RAFA Racing has been to connect people through a shared love of performance and community,” Rafael Martinez, founder of RAFA Racing Club and principal of Maximo Capital, said in a news release. “By pairing XSpace’s forward-thinking condominium design with the exclusive hospitality, networking and high-performance environment of a RAFA Racing Club clubhouse, we’re establishing a community blueprint where passion meets community.”

Each clubhouse will offer:

  • Lounges
  • Dining, working and networking spaces
  • Concierge service
  • Driving simulators
  • Fitness and conditioning capabilities

“We’re building the most valuable community-driven real estate product in America — and RAFA Racing Club is the anchor that makes it unlike anything else on the market," Byron Smith, founder of XSpace, added in a release. “By integrating our flexible, high-end industrial condominiums with RAFA’s world-class hospitality and automotive community spaces, we are completely redefining what commercial real estate can be for the motorsports enthusiast.”

RAFA operates facilities for motorsports fans in Houston and Austin. The clubs, geared toward wealthy people, entrepreneurs, executives, and brand partners, combine a clubhouse, garage, paddock (racing’s version of a locker room), a “human performance” center and driver training programs.

RAFA plans to open seven clubs in the U.S. and three outside the U.S. over the next four years.

XSpace operates a high-end office, warehouse, and lifestyle condo project in Austin and is building a project in Houston that’s set to open in 2027.

Walmart expands drone delivery service to 8 new Houston-area stores

Now Landing

More Walmart delivery drones are now buzzing around Houston-area skies.

In January, Walmart launched its drone delivery service in partnership with Wing at five locations in the Houston area. The retail giant just added eight more stores to its Houston-area drone delivery network.

Wing says the expansion makes drone delivery available to more than 1 million residents of the Houston area. “Many can now bypass notorious Houston traffic to get everyday Walmart essentials delivered by drone in minutes,” Wing said in a release.

The eight Walmart stores that joined the drone delivery network are:

  • 13003 Tomball Pkwy. Houston
  • 12353 FM 1960 Rd. West, Houston
  • 2901 Riley Fuzzel Rd., Spring
  • 20310 U.S. Highway 59, New Caney
  • 1025 Sawdust Rd., Spring, TX 77380
  • 13484 Northwest Fwy., Houston, TX
  • 13750 East Fwy., Houston
  • 3506 Highway 6 South, Houston

Stores where drone delivery was already available are:

  • 14215 FM 2100 Rd., Crosby
  • 1313 N. Fry Rd., Katy
  • 15955 FM 529 Rd., Houston
  • 255 FM 518, Kemah
  • 6060 N. Fry Rd., Katy

Houstonians can learn whether their address is eligible for drone delivery from a Walmart store by visiting wing.com/walmart. Drone-delivered orders can be placed on the Walmart app, the Wing app, or at Walmart.com.

Once an order is ready, it’s loaded onto a delivery drone. The drone then flies up to 60 mph and at a cruising altitude of about 150 feet to reach the customer’s home. The average flight takes less than 5 minutes.

Once it arrives at the customer’s home, the drone stops, hovers at roughly 23 feet, and lowers the order via a tether. Wing says its drones gently lower orders to the ground to protect fragile items like eggs and coffee.
