Four cities from around the world have teamed up on a mission to grow aeronautics, space, and astronomy.

The Space Cities Network launched last month at the International Congress and Convention Association Congress in Abu Dhabi. The first four missions to join the initiative represent four continents and include Houston; Lausanne, Switzerland; Christchurch, New Zealand; and Seoul, South Korea.

“Space is the mirror of humanity and of our community – a quest for tomorrow. A world of exploration and innovation impacting a future that needs support and guidance. Our community, working collectively with Space experts can be one of the keystones of it, and the Space Cities Network is there to help facilitate that,” Space Cities Network Co-Chair Gerald Howard, who represents Switzerland, says in a news release.

Houston First Corp. will oversee the Space City's participation in the international alliance, which was established to increase collaboration between universities, government agencies, industry and corporations.

“Houston is proud to join this international network, leveraging our rich history in space exploration to drive innovation and collaboration across the global space sector,” Michael Heckman, president and CEO of Houston First, says in the release. “As a hub for cutting-edge research and industry, we are committed to fostering partnerships that will propel the future of aeronautics and space.”

According to the new alliance, the space economy is expected to reach $1.8 trillion by 2035, and collaboration across innovation and technology is needed to reach the industry's goals.

“Cities will play an integral, legacy role as hubs for events supporting the space community, hosting conferences, summits, and meetings that bring together industry leaders, researchers, and policymakers,” Co-Chair Claire Hector-Taylor from New Zealand, says.

Houston innovator discusses the power of a pivot and the future of the Space City

houston innovators podcast episode 208

It might surprise many to learn that publicly traded, NASA-backed Intuitive Machines, which has emerged as a commercial leader within lunar access technology development, had several pivots before finding its niche within space innovation.

In fact, as Co-Founder and CTO Tim Crain explains on this week's episode of the Houston Innovators Podcast, the company was founded as a space-focused think tank. Crain, along with his co-founders CEO Steve Altemus and Chairman Kamal Ghaffarian, came together in 2013 to start Intuitive Machines, which recently moved into a $40 million headquarters in the Houston Spaceport.

"At the time, our thought was, 'let's take the best of human space flight engineering processes, disciplines, and know how, and look at how we might commercially deploy that for biomedical, energy, big data, and aerospace,'" Crain says on the show. "We wanted to look at how we use great engineering for some of the hard problems outside of NASA's aerospace sphere."

Crain describes the early years of IM as important to the company because the founders learned how to run a business and meet customers' needs and expectations — things he had little experience from his previous roles as a civil servant at NASA. But Crain says they never fell in love with any of the early technologies and ideas they developed — from long-range drones to precision drilling technologies.

Then, everyone's eyes were on returning to the moon. With this new vision, NASA created the Commercial Lunar Payload Services Program. As Crain explains, this evolution involved looking to hire companies to deliver scientific and developmental payloads to the moon. IM won three of the NASA contracts so far, representing three missions for NASA.

"We dipped our toe in the 'let's develop the moon' river and promptly got pulled all the way in," Crain says. "We left our think tank, broad, multi-sector efforts behind, and really pivoted at that point to focus entirely on NASA's CLPS needs. ... The timing really could not have been any better."

Later this month, Crain will discuss IM's journey in detail for a NASA Tech Talk at the Ion. If you're interested in learning more after listening to the podcast, click here to sign up for the free October 26 event.

With Crain's decades in the space industry, he's observed a resurgence lately, and that has directly impacted Houston's role in the industry.

"The future of Space City is really just beginning to move into a time of producing the hardware here and having Houstonians make the spacecraft, space systems, and the technologies that we use to explore and develop the solar system," Crain says on the show.

High-tech virtual reality experience blasts into the Space City

to infinity and beyond

From the earliest days of our circling the planet in a tiny NASA capsule — to Elon Musk's SpaceX current commercial journeys — Houston and space travel will be forever and inexorably linked.

Fitting, then, that an unprecedented new immersive experience centered on the International Space Station (ISS) is making its U.S. debut here in Space City. "The Infinite"— a multi-sensory, interactive virtual reality experience — will zoom into Sawyer Yards on December 20 for a special, and limited, run, organizers announced.

This sprawling, 12,500-square-foot exhibition shuttles viewers into a never-before-seen perspective of life on the ISS, bringing an almost-too-real feeling of being in outer space.

Tickets are on sale now for a soft open preview period beginning on December 20; admission is $29. Tickets then jump to $36 for the full-scale limited engagement beginning on January 13, 2022.

Boasting footage shot over a period of nearly three years that created some 200 hours of high-end virtual reality scenes, the four-part immersive series documents the life of eight international astronauts inside — and outside — the International Space Station. (The outside experience promises to be an especially wild ride.) The show comes to Houston off a wildly popular Canadian run in Montreal.

Specific to this Houston launch, the show boasts new footage from the first-ever cinematic spacewalk captured in 3D — 360-degree virtual reality shot outside the International Space Station on September 12, 2021 — while offering visitors a self-directed experience aboard the ISS itself, according to a press release.

Throughout the 60-minute journey, per press materials, viewers will engage with physical objects, virtual reality, multimedia art, soundscapes, light design, and even the subtle scents of a forest, meant to evoke memories of stargazing while lying on the grass.

"The Infinite" is the brainchild of Montreal-based Infinity Experiences, a joint venture of PHI Studio and Felix & Paul Studios, and is an extension of the recent Primetime Emmy Award-winning immersive series, "Space Explorers: The ISS Experience," the largest production ever filmed in space, produced by Felix & Paul Studios in association with Time Studios.

That this show will run next year is also especially timely for Houston's space saga. Next year marks the 60th anniversary of President John F. Kennedy's famous moon-shot speech given at Rice University on September 12, 1962. That speech, with its now-legendary "we choose to go to the moon" line, galvanized the nation and propelled the U.S. into a space race that found Neil Armstrong and "Buzz" Aldrin on the moon only seven years later.

"The exploration of space and the unknown is an endless source of fascination to us," said Félix Lajeunesse, co-founder of Felix & Paul Studios and creative director of The Infinite, in a statement.

"We are thrilled to bring The Infinite to Houston — the global epicenter of human space exploration — to share this massive, fully immersive exhibition, and we look forward to virtually transporting thousands of people off the Earth to enjoy the joy and wonder of space with audiences in the U.S. This unprecedented project is made possible thanks to our partners at NASA, the ISS National Lab, international space agencies and the incredible power of virtual reality."

Overheard: Houston experts weigh in on the future of the Space City

EAVESDROPPING IN HOUSTON

Houston's been known as the Space City for about 50 years since "Houston" was the first word spoken from the surface of the moon. But whether or not that nickname will continue to stick was up for debate at a 2019 SpaceCom panel on November 21.

The panel, entitled "Regional Benefits of a Commercial Space Economy: Case Study Houston," the panelists set out to discuss the city's rich history of space exploration, as well as to answer the question of where Houston's space industry is headed.

"We could ask that question in a passive way, but my preference is that here in Houston we ask the question now, answer it, and be very proactive and deliberate about making sure we get the outcome that we want," says Vernon McDonald, senior vice president at KBR and moderator of the discussion.

If you missed the enlightening discussion, here are a few takeaways from the panelists.

"Houston is in this great position to be this beacon to lead entrepreneurs and inspire other regions to explore further."

— Rick Jenet, director of the Center for Advanced Radio Astronomy. Jenet, who is based in Brownsville, Texas, is working to develop a vibrant commercial space hub in South Texas. In a lot of ways, the area looks to Houston's history for its development, he says.

"We built a community of engineers and scientists and a workforce that's all vested in the outcome of the human space flight program."

— Steve Altemus, president and CEO of Intuitive Machines. The creation of the Johnson Space Center developed generations within the community of scientists and engineers, but, moving forward, Houston has to be intentional about building its talent base. "I'm very passionate about doing that here in Houston," Altemus adds.

"There's a beacon of hope for our community if we can organize around it and attract commercial business here to keep this city the Space City, but redefine ourselves as a commercial space hub."

— Altemus says, adding that it's going to take further development, talent, and funds — like what's happening at the Houston Spaceport — to make this transition.

"Over the years, Houston took space for granted. Houston started to focus on the bigger industries that brought in funding and jobs."

— Steven Gonzalez, technology transfer strategist at NASA's Johnson Space Center. At the risk of being unpopular, Gonzalez mentions that the city's attention has been diverted from space exploration. However, he adds, there are new initiatives from the Greater Houston Partnership and Houston First that are picking up the slack.

"The answers to Houston delivering on its potential is going to be collaborations — how well we collaborate."

— Harvin Moore, president at Houston Exponential. Houston is collaborative, and the city needs to make sure its resources are inclusive as commercial space develops in town.

"I'd like to say that Houston is the birthplace of human space flight, and in 50 years, I'd like to see the city be the leader and the point of the spirit for human exploration internationally and commercially out in mars and beyond.

— Altemus responds when asked about the Space City's next 50 years.

"I think what Houston will be most proud of in 50 years is that we played an extremely important role in shaping how Texas leads the world in commercial space exploration."

— Jenet, who mentions that there's space exploration innovation happening statewide.

"When you think about what [leading space exploration] company will be here fifty years from now, I don't think it's been created yet. But I would like that company to be here in Houston."

— Gonzalez says, adding that the first trillionaire is likely to make his or her fortune in the space industry, and he wants that money here in Houston.

"A lot of our future is not going to be based on what huge companies or government are doing but much more about entrepreneurs."

— Moore says, emphasizing the need for developing startup resources in Houston.

Houston can stay the Space City within medical and health innovation

Guest column

Space has captured the imagination of mankind since we first looked up at the night sky. We've reached out to touch the stars, and now endeavor to inhabit them.

Earlier this month, a prominent collection of experts on space health attended the first Space Health Innovation Conference co-hosted by the University of California, San Francisco, and Houston-based Translational Research Institute for Space Health.

As NASA eyes a return to the moon with the Artemis Program, attendees of the Space Health Innovation Conference advanced a national discussion of human space exploration by seeking to manage the many health risks associated with humans during space flight. The event included NASA leadership, innovative companies, commercial space vendors, as well as leaders from the space health and life sciences communities.

The conference's goal is to inform, inspire and invite participation in the exciting challenge of optimizing health and medical management in space environments.

With its headquarters in Houston, TRISH partnered with the Human Research Program at Johnson Space Center to source and seed the best emerging health technologies to support NASA's space exploration. TRISH is based out of the Center for Space Medicine at Baylor College of Medicine and is a consortium that includes the rich space pedigree of the Massachusetts Institute of Technology and the California Institute of Technology. The Space Health Innovation Conference is the result of a grant by TRISH to UCSF. TRISH has also hosted Space Health focused events at the MIT Media lab and at Caltech.

TRISH's main charge is finding disruptive health technologies and new scientists to fuel the US Space Program. TRISH explores emerging areas of science that support health and human performance in the harsh environment of microgravity and high radiation. TRISH funds novel research in artificial intelligence, omics, human computer interfaces, behavioral health and beyond. Projects all share one goal: predicting and protecting future Mars explorers. And NASA leadership encourages TRISH to take the risks that could mean huge leaps forward.

Innovation and risk tolerance are hallmarks of Houston and its rich history. From the city's humble origins, to Jesse Jones's national financial leadership, to the building of the Houston Ship Channel, and to the explosion of the energy industry, Houston has always dared to leap forward. President John F. Kennedy's iconic speech entitled "Address at Rice University on the Nation's Space Effort" declared the US ambition to embrace the new frontier of space and conquer the moon. Humble Oil donated the 1,620 acres for JSC to Rice University, who then sold the land to NASA for $20. (Humble Oil would later become Exxon Mobil.)

JSC housed flight control, space flight training, and the NASA Astronaut Corps. JSC gave Houston the nickname "Space City", which led to the naming of the local NBA team to be the Rockets and the local MLB team to be the Astros. JSC's support for the astronaut corps began with the Lunar Receiving Laboratory, which evaluated the Apollo astronauts upon return to Earth. And the Christopher C Kraft Mission Control facility has directed all crewed space flights since the early Gemini program. An American flag flies atop Mission Control at JSC every day that an American is in space. That flag has flown continuously since November 2, 2000.

Nearly two decades since Bill Shepherd first boarded the International Space Station, the conversation around supporting human health and performance in space continues. And Houston will continue to lead the way for all our sakes, in space and on terra firma.

Generation Park lands new facility to scale xeno-organ production

Organ innovation

Maryland-based United Therapeutics Corp. has opened a new 77,448-square-foot facility to manufacture xeno-organs in Northeast Houston’s growing biotech hub, Generation Park.

The new Houston location is United Therapeutics’ third Designated Pathogen-Free (DPF) site, named for transplant pioneers Dr. Bartley P. Griffith and Dr. Robert A. Montgomery. The company says the new facility will enable it to scale commercial production of its xeno-organs once they receive regulatory approval.

An existing DPF facility in Virginia is supporting clinical trials for the xeno-organs, and a third site in Minnesota will also focus on commercialization with the Houston site, according to the company.

Xeno-organs are organs taken from a non-human animal source and transplanted, implanted or infused into a human recipient.

Currently, United Therapeutics is advancing clinical trials to support a Biologics License Application with the U.S. Food and Drug Administration for its investigational-stage xenotransplantation, UKidney, UThymoKidney and UHeart products. The products all involve working with the genes from humans and pigs.

In 2025, Chron.com reported the company was working to construct an estimated $96 million facility to breed genetically engineered animals. Head of investor relations at United Therapeutics Dewey Steadman told the Houston Business Journal in 2025 that the pigs’ DNA will be edited. In November 2024, a 53-year-old woman in Alabama received a transplanted kidney from UKidney that had 10 gene edits. She had the transplant removed in April 2025, after her body rejected it.

The Dr. Bartley P. Griffith and Dr. Robert A. Montgomery Xenograft Production Facility requires a “strictly controlled, biosecure barrier environment, including air filtration, filtered water, filtered feed supplies, and state-of-the-art decontamination entryways,” according to the company. Being pathogen-free means it includes calibrated air and water conduits to support the transplantability of xenograft products and to prevent contamination. For energy considerations, the building also features solar arrays.

“With our third xenograft production facility now open and clinical trials underway, United Therapeutics is moving closer to its goal of providing transplantable organs to the people who need them,” Martine Rothblatt, chairperson and CEO of United Therapeutics, said in a news release. “It is fitting that this facility is named for Dr. Griffith and Dr. Montgomery, whose first-in-human surgeries turned xenotransplantation from a theoretical possibility into a clinical reality.”

The facility, which wrapped construction in August, is located at 11848 Common Dock Dr. in Generation Park, which will house manufacturing sites for pharmaceutical heavyweights Bristol Myers Squibb and Eli Lilly. Last fall, Eli Lilly tapped Generation Park for its $6.5 billion manufacturing plant, and Bristol Myers Squibb made a $2.3 billion investment in August to bring its state-of-the-art site to the master-planned commercial district.

Elon Musk's SpaceX reports profit as AI and satellite businesses booms

Booming Business

SpaceX reported a bigger quarterly profit than expected on Tuesday, October 20, as its satellite communications and artificial intelligence businesses boomed.

The company, run by Elon Musk, posted a profit for the three months through September 2026 of $4.4 billion, or 35 cents per share, reversing a year-ago loss and easily topping Wall Street's expectations. Revenue soared to $14.6 billion, up 161%.

On a conference call with analysts, Musk suggested a merger with his electric car company Tesla might be in the works, something that has been rumored for months. He said both companies formed “special committees” of independent directors to discuss the issue, though he played down the chances of an imminent deal.

“Some people out there assume that a SpaceX and Tesla merger is a certainty,” he said. “I think that would be overstating it.”

The AI business became SpaceX's largest by revenue in the third quarter, although the Starlink satellite service remains the biggest profit generator.

“They beat across all metrics and the Starlink business looks to be accelerating,” said Dan Ives, an analyst at Yorkville Ives. “This is just what (Wall) Street wanted.”

The stock rose 7.5% in after-hours trading.

Musk also told analysts that for next month's launch of its Starship rocket, SpaceX will attempt to grab both the booster and ship with mechanical arms upon return to base, a key step toward demonstrating it can reuse the massive spacecraft.

“The only way that we can extend consciousness beyond Earth on a sustained basis is with a fully reusable orbital launch vehicle,” Musk said, calling the attempt, if successful, “a massive technology milestone.”

SpaceX hopes to get Starship on a regular launch pattern in preparation for NASA's upcoming lunar missions.

The company already has huge contracts with the federal government, and House Democrats have called for investigations into those contracts and Musk’s work with the Department of Government Efficiency. Musk has spent $276 million since July in support of Republican candidates.

In a filing for its initial public offering in June, SpaceX warned that a change in control of Congress could have a “material and adverse impact on our growth and competitive position.”

Musk recently drew criticism from politicians in Washington after speeds for a military version of SpaceX's satellite communications service were slowed for Ukraine following President Donald Trump's deal to get more diesel oil from Russia amid a push to end the war. The Wall Street Journal reported Tuesday that it was Musk who ordered the slowdown, impeding Ukraine’s use of drones along the front. SpaceX did not immediately respond to an Associated Press request for comment on the Journal story.

Both Trump and Musk have denied responsibility for the slowdown.

As midterm elections near, Musk on Monday promised to give one share of SpaceX to “every kid in America” next year, though he provided no details on how the distribution would be carried out. With communities nationwide protesting the construction of large data centers and concerns about AI safety, AI companies are trying to build goodwill. Anthropic pledged to commit 5% of its shares to a new “public benefit” fund.

SpaceX shares have been under pressure over concerns that the company was spending too much on major projects to compete with rivals such as Anthropic. The company said capital expenditures totaled $19.6 billion last quarter, nearly triple the figure from a year earlier, and it forecast spending would grow to $35 billion to $40 billion in the current quarter.

Shares of SpaceX closed Tuesday at $147.79, down from a peak near $201 after its IPO, which made Musk the world’s first trillionaire at the time. But the share prices for SpaceX and Tesla have since dropped, reducing his net worth to $925 billion, according to Forbes magazine.

Tesla reports third-quarter financial results Wednesday. Last week, Tesla unveiled a new Roadster sports car that in some versions may include thrusters allowing it to briefly fly using SpaceX technology — though experts say anything usable for drivers is a long shot.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

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

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

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.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.
