A small surgical robot at the International Space Station completed its first surgery demo in zero gravity last week, and one of the surgeons tasked with the remote robotic operations on simulated tissue was Houston-based Dr. Theodoros Voloyiannis.

Voloyiannis took part in what is being referred to as “surgery in space” by being one of the six doctors remotely controlling spaceMIRA — Miniaturized In Vivo Robotic Assistant — that performed several operations on simulated tissue at the lab located in the space station. The surgeons operated remotely from earth in Lincoln, Nebraska. The remote surgeons worked to control the robot's hands to provide tension to the simulated tissue made of rubber bands. They then used the other hand to dissect the elastic tissue with scissors.

“I said during the procedure ‘it was a small rubber band cut, but a great leap for surgery,’“ Voloyiannis tells InnovationMap. “This was a huge milestone for me personally in my career.”

The robot was developed by Virtual Incision Corporation, and made possible through a partnership between NASA and the University of Nebraska. The team of surgeons took part in a demonstration that is considered a common surgical task, as they dissected the correct piece of tissue under pressure.

Latency is the time delay between when the command is sent and the robot receives it, and that was the big challenge the team faced. The delay was about 0.85 of a second according to what the colorectal surgeon who worked on spaceMIRA Dr. Michael Jobst said to CNN. The demo overall was a success according to the team, and posed a new-found adrenaline rush due to the groundbreaking innovation.

“The excitement of the new and the unknown,” Voloyiannis says on the feeling of doing the first operation of its kind. “I never thought I’d be doing something like this when I was in training and in medical school.”

Voloyiannis serves as the chairman of colon and rectal surgery for The US Oncology Network. He was chosen for this experiment due to his experience and expertise performing robotic colorectal surgery. Voloyiannis and the developers are hopeful that this type of technology will soon allow doctors to perform this specialized robotic surgery on patients living in rural areas without a specialized surgeon nearby, military battlefields, as well as regularly in space one day.

“The same concept of remote surgery regularly in space could certainly be entertained,” Voloyiannis says. “When you do things with an absence of gravity and perform a surgery in that environment — of course that changes the way we do things. When you have an absence of gravity with bodily fluids, it is a very hard surgery, but with partial gravity that idea can be entertained.

"Remotely, internet connectivity would have to be considered and you’d have someone remote like me here, while potentially there you’d have someone with less training doing the procedure there guiding the robot," he continues. "It’s quite the concept though.”

UH lab using mixed reality to optimize designs for the Moon and Mars

hi, tech

University of Houston researchers and students are bringing multiple realities together to help improve the design process for crewed space missions.

Helmed by Vittorio Netti, a researcher for UH and a space architect, the university has launched an XR Lab within the University of Houston architecture building. The lab allows researchers to combine mixed reality (MR), virtual reality (VR), augmented reality (AR) and extended reality (XR) to "blend the physical and digital worlds" to give designers a better understanding of life in space, according to a release from UH.

In the lab researchers can wear MY space suits and goggles, take a VR space walk, or feel what it's like to float to the International Space Station with the help of XR and a crane.

The area in which the researchers conduct this work is known as the "cage" and was developed during a six-month research and design study of lunar surface architecture sponsored by Boeing, which aimed to learn more about the design of a lunar terrain vehicle and a small lunar habitat.

The work is part of UH's Sasakawa International Center of Space Architecture (SICSA), which is led by Olga Bannova, a research associate professor and director of the space architecture graduate program at UH.

She says work like this will drastically cut down research and development time when designing space structures.

“These technologies should be harnessed to mitigate the dependency on physical prototyping of assets and help optimize the design process, drastically reducing research-and-development time and providing a higher level of immersion,” Bannova said in a statement.

Today the research team is shifting its focus on designing for a Mars landing. In the future, they aim to demonstrate and test the system for habitats designed for both lunar and Martian surfaces. They are also working with Boeing to test designs in microgravity, or zero gravity, which exists inside the International Space Station.

6 Houston entrepreneurs land on coveted Inc. Female Founders 500 list

the future is female

Six Houston female entrepreneurs and innovators were named to the 2026 Female Founders 500 list.

The annual list compiled by Inc. Magazine recognizes female founders based in the U.S. who have built businesses that have moved their industries forward. The group collectively generated approximately $12.3 billion in 2025 revenue and $12.2 billion in funding to date, according to Inc. Five Houstonians were named to the list last year.

"Each year, we are increasingly amazed by the extraordinary leaders on our Inc. Female Founders 500 list," Bonny Ghosh, editorial director at Inc., said in a news release. "The honorees on this year's list include innovators in AI, beauty and wellness trendsetters winning devoted fans, and nonprofit leaders making a real impact in their communities. Together, they're showing all of us what trailblazing female leadership looks like."

The Houston founders are:

  • Sassie Duggleby, CEO and co-founder of Houston space tech and engine company Venus Aerospace. Duggleby also serves on the Texas Space Commission board of directors.
  • Stephanie Murphy, CEO and executive chairman of Aegis Aerospace, which provides space services, spaceflight product development, and engineering services. Murphy also serves as chair of the Texas Aerospace Research and Space Economy Consortium Executive Committee.
  • Laureen Meroueh, CEO and founder of Hertha Metals, which has developed a cost-effective and energy-efficient process that converts low-grade iron ore of any format directly into molten steel or high-purity iron in a single step.
  • LaToshia Norwood, managing partner of L'Renee & Associates (LRA), a full-service project management consulting firm.
  • Lauren Rottet, president and founding principal of Rottet Studio, an international architecture and design firm focused on corporate, lifestyle and hospitality projects
  • Nina Magon, founder and CEO of Nina Magon Studio / Nina Magon Consumer Products, a residential and commercial interior design company. She also co-founded KA Residences earlier this year.

"Grateful to be recognized again on the Inc. Female Founders 500," Duggleby said in a LinkedIn post. "The best part of building Venus Aerospace has been working with an incredible team pushing the boundaries of flight—and helping bring more women into aerospace along the way.

Meroueh, whose company emerged from stealth last year, voiced a similar push for bringing more women into the fold.

"We've seen a 7x jump in female-led IPOs over the last decade, from just two in 2014 (less than 1% of all IPOs) to 14 in 2024 (nearly 9% of all IPOs). Progress is happening," Meroueh shared in a LinkedIn post. "Yet, less than 1% of venture funding in hard tech goes to female-founded companies. But as my friend Ana Kraft says, the right man for the job may be a woman."

Twenty-nine Texas female founders made this list, including Amber Venz Box, founder of the Dallas-based LTK shopping platform, and Cheryl Sew Hoy, CEO and founder of Austin-based Tiny Health, a fast-growing at-home microbiome health platform. See the full list of winners here.

NASA clears Artemis moon rocket for April launch with 4 astronauts

3, 2, 1...

NASA has cleared its moon rocket on for an April launch with four astronauts after completing the latest round of repairs.

The 322-foot (98-meter) rocket will roll out of the hangar and back to the pad at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years.

The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered.

Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April.

The space agency has only six days at the beginning of April to launch before standing down until April 30 into early May.

"It's a test flight and it is not without risk, but our team and our hardware are ready,” NASA's Lori Glaze told reporters at the end of the two-day flight readiness review.

Glaze and other NASA officials declined to provide the risk probabilities for the upcoming mission.

History has shown that a new rocket has essentially a 50% chance of success, said John Honeycutt, chair of the mission management team.

There's so much gap since the only other SLS flight — more than three years ago without anyone on board — that it's difficult to understand any risk assessment numbers, Honeycutt said.

“It's not the first flight," Glaze said. "But we're also not in a regular cadence. So we definitely have significantly more risk than a flight system that's flying all the time.”

Late last month NASA's new administrator, Jared Isaacman, announced a major overhaul of the Artemis program to speed things up and, by doing so, reduce risk.

Dissatisfied with the slow pace and lengthy gaps between lunar missions, he added an extra practice flight in orbit around Earth for next year. That is now the new Artemis III, with the moon landing by two astronauts shifted to Artemis IV. Isaacman is targeting one and maybe even two lunar landings in 2028.

NASA's Office of Inspector General warned in an audit that the space agency needs to come up with a rescue plan for its lunar crews. Landing near the moon's south pole will be riskier than it was for the Apollo astronauts closer to the equator given the rough polar terrain, according to the report.

The report cited the lunar landers as the top contributor for potential loss of crew during the first few Artemis moon landings. It listed the space agency’s loss-of-crew threshold at 1-in-40 for lunar operations and 1-in-30 for Artemis missions overall.

Contracted by NASA to provide the moon landers for astronauts, Elon Musk's SpaceX and Jeff Bezos' Blue Origin have accelerated work in order to meet the new 2028 target date. The inspector general's office said many technical challenges remain including refueling their landers in orbit around Earth before flying to the moon.

NASA sent 24 astronauts to the moon during Apollo, 12 of whom landed on it. All but one of the moonshots — Apollo 13 — achieved their prime objectives. The program ended with Apollo 17 in 1972.

Kinder leads 19 Houstonians on Forbes' World's Billionaires List 2026

World's Richest 2026

According to Forbes, there has “never been a better time to be a billionaire” than in 2026, and the publication's newest World’s Billionaires List has revealed the 19 Houston billionaires that have risen among the wealthiest worldwide.

Kinder Morgan chairman Richard Kinder surpassed hospitality honcho Tilman Fertitta as the richest billionaire in Houston, ranking No. 232 on the global list with an estimated net worth of $13 billion. His net worth has grown by $2.4 billion since last year.

Fertitta, 68, may not be the richest Houstonian anymore, but his wealth is still on the rise. He ranked 268th on the list with an estimated net worth of $11.7 billion, up from $11.3 billion last year.

Out of the 390 billionaire newbies that made their debut onto the list this year, one of them calls Houston home: restaurateur and commodities trader Ignacio Torras. Torras, 61, is the founder and CEO of global commodities trading company Tricon Energy, and he owns Michelin-starred local restaurant BCN Taste & Tradition and its sister eatery MAD. But that's not all he spends his time doing, according to Forbes.

"In 2024 Torras launched a soccer tournament for neurodivergent players called the Genuine Cup," his profile said. "Last year 800 players and 30 teams from around the world played at Rice University stadium."

Torras debuted as No. 2600 on the list with an estimated net worth of $1.5 billion.

Houston-born multi-hyphenate superstar Beyoncé Knowles-Carter also staked a claim among the world's richest people in 2026. She ranked No. 3332 on the list with a net worth of $1 billion, thanks to her "years of music sales, touring and collecting art with her already-billionaire husband Jay-Z (estimated net worth: $2.8 billion)," Forbes said.

"The majority of pop star Beyonce’s net worth comes from her roughly three decades as a solo performer and a member of the girl-group Destiny's Child," her profile said. "She holds the record for the most Grammy wins ever, with 35, and won her first Album of the Year trophy in 2025. She and her billionaire husband Jay-Z purchased a $200 million Malibu mansion in 2023, in what was the most expensive home sale in California history."

Beyoncé also ranks No. 21 in the publication's separate list of The World's Celebrity Billionaires.

Here's how the rest of Houston's billionaires fared on this year's list:

  • Toyota mega-dealer Dan Friedkin: No. 279; $11.4 billion, up from $7.7 billion
  • Pipeline heir Randa Duncan Williams: tied for No. 323 with an estimated net worth of $10.2 billion, up from $9.3 billion in 2025.

  • Frontier Airlines chairman William Franke: No. 3332; $1 billion, down from $1.2 billion

Elsewhere in Texas

Austin billionaire Elon Musk was declared the world's richest person for the second consecutive year, and Forbes said his “grip on the top spot is as strong as it’s ever been.”

“Musk became the first person to hit $500 billion in wealth, in October,” Forbes said. “Then $600 billion and $700 billion, within four days in December. Then $800 billion, in February.”

The Tesla, SpaceX, and xAI founder’s current net worth has skyrocketed to $839 billion — a shocking $497 billion more than his 2025 net worth.

In Dallas-Fort Worth, Walmart heiress Alice Walton has maintained her elite status as the world’s richest woman for the third year in a row. Walton is the 14th richest person on the planet with a current net worth of $134 billion, an eye-catching $33 billion higher than her 2025 net worth. She is the first American woman worth $100 billion, and one of only 20 “centi-billionaires” worldwide claiming 12-figure fortunes, also known as the "$100 Billion Club."

Koch Inc. stakeholder Elaine Marshall and her family are the richest Dallas residents, ranking No. 71 globally with an estimated net worth of $30.9 billion. Her net worth has grown by $2.6 billion since last year.
