A Houston-based space tech company has revealed details on two of its commercial partnerships with NASA.

NASA and Axiom Space have again signed a mission order for a private astronaut mission to the International Space Station. The mission will commence sometime in November or on and will be from the agency’s NASA’s Kennedy Space Center in Florida. Axiom Mission 3 is the third mission of its kind and, according to a statement from NASA, is expected to be a 14-day trip.

The ISS's Multilateral Crew Operations Panel will approve four proposed crew members and two back up crew submitted by Axiom for the Ax-3 mission. The crew will be expected to train for their flight with NASA, international partners, and SpaceX beginning this spring, according to NASA.

“Axiom Space’s selection to lead the next private astronaut mission to the International Space Station enables us to continue expanding access to nations, academia, commercial entities, and emerging industries to research, test, and demonstrate new technologies in microgravity,” says Michael Suffredini, CEO and president of Axiom Space, in the release. “As NASA’s focus shifts back to the Moon and on to Mars, we are committed to transforming low-Earth orbit into a global space marketplace, where access to space moves beyond the partners of the space station to nations, institutions and individuals with new ideas fueling a thriving human economy beyond Earth.”

Axiom's historic first commercial launch was in spring of 2022, and Ax-2, which will launch the first Saudi astronauts to visit the ISS, is expected to launch this spring. In addition to these two missions, Axiom has been tasked by NASA to develop spacesuits and space station technology.

After several months of working on the suits, Axiom has revealed the details of the technology that will be worn by NASA astronauts returning to the moon on the Artemis III mission that's scheduled to land near the lunar south pole in 2025.

“We’re carrying on NASA’s legacy by designing an advanced spacesuit that will allow astronauts to operate safely and effectively on the Moon,” says Suffredini in a statement from the company. “Axiom Space’s Artemis III spacesuit will be ready to meet the complex challenges of the lunar south pole and help grow our understanding of the Moon in order to enable a long-term presence there.”

Called the Axiom Extravehicular Mobility Unit, or AxEMU, the prototype was revealed at Space Center Houston’s Moon 2 Mars Festival today, March 15. According to Axiom, a full fleet of training spacesuits will be delivered to NASA by late this summer.

At the same time as the Ax-3 mission announcement, NASA also announced that it has selected Firefly Aerospace of Cedar Park, Texas, to carry multiple payloads to the far side of the Moon. According to NASA, the commercial lander will deliver two agency payloads, as well as communication and data relay satellite for lunar orbit, which is an European Space Agency collaboration with NASA.

The contract — awarded for around $112 million — is targeted to launch in 2026 through NASA’s Commercial Lunar Payload Services, or CLPS, initiative, and part of the agency’s Artemis program. It's the second award to Firefly under the CLPS initiative.

“The diversity of currently available commercial orbital human spaceflight opportunities is truly astounding. NASA’s commercial crew flights to the space station for our government astronauts paved the way for fully private missions to space like Inspiration4 and Polaris as well as private astronaut missions to the orbiting laboratory like the one we are announcing today,” says Phil McAlister, director of commercial space at NASA Headquarters in Washington, in the release. “We are starting to see the incorporation of space into our economic sphere, and it is going to revolutionize the way people see, use, and experience space.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
