The two astronauts stuck at the International Space Station since June welcomed their new ride home with Sunday’s arrival of a SpaceX capsule.

SpaceX launched the rescue mission on Saturday with a downsized crew of two astronauts and two empty seats reserved for Butch Wilmore and Suni Williams, who will return next year. The Dragon capsule docked in darkness as the two craft soared 265 miles (426 kilometers) above Botswana.

NASA switched Wilmore and Williams to SpaceX following concerns over the safety of their Boeing Starliner capsule. It was the first Starliner test flight with a crew, and NASA decided the thruster failures and helium leaks that cropped up after liftoff were too serious and poorly understood to risk the test pilots’ return. So Starliner returned to Earth empty earlier this month.

The Dragon carrying NASA’s Nick Hague and the Russian Space Agency’s Alexander Gorbunov will remain at the space station until February, turning what should have been a weeklong trip for Wilmore and Williams into a mission lasting more than eight months.

Two NASA astronauts were pulled from the mission to make room for Wilmore and Williams on the return leg.

“I just want to say welcome to our new compadres,” Williams, the space station commander, said once Hague and Gorbunov floated inside and were embraced by the nine astronauts awaiting them.

Hague said it was a smooth flight up. “Coming through the hatch and seeing all the smiles, and as much as I've laughed and cried in the last 10 minutes, I know it's going to be an amazing expedition," he said.

NASA likes to replace its station crews every six months or so. SpaceX has provided the taxi service since the company’s first astronaut flight in 2020. NASA also hired Boeing for ferry flights after the space shuttles were retired, but flawed software and other Starliner issues led to years of delays and more than $1 billion in repairs.

Starliner inspections are underway at NASA’s Kennedy Space Center, with post-flight reviews of data set to begin this week.

“We’re a long way from saying, ‘Hey, we’re writing off Boeing,’” NASA’s associate administrator Jim Free said at a pre-launch briefing.

The arrival of two fresh astronauts means the four who have been up there since March can now return to Earth in their own SpaceX capsule in just over a week, bringing the station's crew size back down to the normal seven. Their stay was extended a month because of the Starliner turmoil.

Although Saturday’s liftoff went well, SpaceX said the rocket’s spent upper stage ended up outside its targeted impact zone in the Pacific because of a bad engine firing. The company has halted all Falcon launches until it figures out what went wrong.was extended a month because of the Starliner turmoil.

Texas space tech company scores $843M to build the vehicle that'll decommission ISS

getting launch ready

NASA has awarded SpaceX an $843 million contract to build the vehicle that will bring the International Space Station out of its longtime orbit of Earth when its operating lifespan ends in a few more years.

SpaceX, a privately held company controlled by technology mogul Elon Musk, who announced the California-founded company's relocation to Texas earlier this year, will build the vehicle that will bring down the space station, but NASA will still oversee the eventual mission.

The International Space Station, launched in 1998, is expected to be needed to be brought out of orbit by 2030. The station is operated by space agencies from the U.S., Europe, Japan, Canada and Russia. All the countries involved have pledged to operate the station until 2030 except Russia, which has only committed to participate until 2028.

Crews of astronauts have been occupying the space station since 2000.

“The orbital laboratory remains a blueprint for science, exploration, and partnerships in space for the benefit of all,” said Ken Bowersox, NASA's associate administrator for space operations mission directorate.

The contract is another vote of confidence in the technological prowess of SpaceX, a rocket maker based in Hawthorne, California, that Musk founded in 2002 to explore new frontiers in space. Musk, 52, then became the driving force behind in Tesla, the electric car maker that accounts for most of his estimated fortune of $220 billion.

A Houston space tech company has also won NASA contracts relating to the future of the ISS. Houston-based tech unicorn Axiom Space is currently building out its Axiom Station, which received a $140 million grant from NASA. The company is also working with NASA on new and innovative spacesuits for the next generation of astronauts.

Earlier this summer, SpaceX celebrated its most successful launch of its mega Starship rocket, which completed its first full test flight Thursday, returning to Earth without exploding after blasting off from Texas.

Houston surgeon takes part in first-of-its-kind surgery in space

remote control health care

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.”

The doctors had to account for nearly a second of delay in connectivity. Photo courtesy of Texas Oncology

Houston space tech company secures third NASA mission, reveals new spacesuits

ready for liftoff

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.”

NASA launches new research projects toward astronauts on ISS

ready to research

For the 26th time, SpaceX has sent up supplies to the International Space Station, facilitating several new research projects that will bring valuable information to the future of space.

On Saturday at 1:20 pm, the SpaceX Dragon spacecraft launched on the Falcon 9 rocket from NASA’s Kennedy Space Center in Florida — bringing with it more than 7,700 pounds of science experiments, crew supplies, and other cargo. The anticipated docking time is Sunday morning, and the cargo spacecraft will remain aboard the ISS for 45 days, according to a news release from NASA.

Among the supplies delivered to the seven international astronauts residing on the ISS are six research experiments — from health tech to vegetation. Here's a glimpse of the new projects sent up to the scientists in orbit:

Moon Microscope

Seeing as astronauts are 254 miles away from a hospital on Earth — and astronauts on the moon would be almost 1,000 times further — the need for health technology in space is top of mind for researchers. One new device, the Moon Microscope, has just been sent up to provide in-flight medical diagnosis. The device includes a portable hand-held microscope and a small self-contained blood sample staining tool, which can communicate information to Earth for diagnosis.

"The kit could provide diagnostic capabilities for crew members in space or on the surface of the Moon or Mars," reads a news release. "The hardware also may provide a variety of other capabilities, such as testing water, food, and surfaces for contamination and imaging lunar surface samples."

Fresh produce production

Salads simply aren't on the ISS menu, but fresh technology might be changing that. Researchers have been testing a plant growth unit on station known as Veggie, which has successfully grown a variety of leafy greens, and the latest addition is Veg-05 — focused on growing dwarf tomatoes.

Expanded solar panels

Thanks to SpaceX's 22nd commercial resupply mission in 2021, the ISS installed Roll-Out Solar Arrays. Headed to the ISS is the second of three packages to complete the panels that will increase power for the station by 20 to 30 percent. This technology was first tested in space in 2017 and is a key ingredient in future ISS and lunar development.

Construction innovation

Image via NASA.gov

Due to the difference of gravity — and lack thereof — astronauts have had to rethink constructing structures in space. Through a process called extrusion, liquid resin is used to create shapes and forms that cannot be created on Earth. Photocurable resin, which uses light to harden the material into its final form, is injected into pre-made flexible forms and a camera captures footage of the process, per the news release.

"The capability for using these forms could enable in-space construction of structures such as space stations, solar arrays, and equipment," reads the release. "The experiment is packed inside a Nanoracks Black Box with several other experiments from the Massachusetts Institute of Technology Media Lab and is sponsored by the ISS National Lab."

Transition goggles

It's a bizarre transition to go from one gravity field to another — and one that can affect spatial orientation, head-eye and hand-eye coordination, balance, and locomotion, and cause some crew members to experience space motion sickness, according to the release.

"The Falcon Goggles hardware captures high-speed video of a subject’s eyes, providing precise data on ocular alignment and balance," reads the release.

On-demand nutrients

Image via NASA.gov

NASA is already thinking about long-term space missions, and vitamins, nutrients, and pharmaceuticals have limited shelf-life. The latest installment in the five-year BioNutrients program is BioNutrients-2 , which tests a system for producing key nutrients from yogurt, a fermented milk product known as kefir, and a yeast-based beverage, per the release.

"The researchers also are working to find efficient ways to use local resources to make bulk products such as plastics, construction binders, and feedstock chemicals. Such technologies are designed to reduce launch costs and increase self-sufficiency, extending the horizons of human exploration," reads the release.

Houston neighbor named richest small town in Texas for 2025

Ranking It

Affluent Houston neighbor Bellaire is cashing in as the richest small town in Texas for 2025, according to new study from GoBankingRates.

The report, "The Richest Small Town in Every State," used data from the U.S. Census Bureau's American Community Survey to determine the 50 richest small towns in America based on their median household income.

Of course, Houstonians realize that describing Bellaire as a "small town" is a bit of misnomer. Located less than 10 miles from downtown and fully surrounded by the City of Houston, Bellaire is a wealthy enclave that boasts a population of just over 17,000 residents. These affluent citizens earn a median $236,311 in income every year, which GoBankingRates says is the 11th highest household median income out of all 50 cities included in the report.

The average home in this city is worth over $1.12 million, but Bellaire's lavish residential reputation often attracts properties with multimillion-dollar price tags.

Bellaire also earned a shining 81 livability score for its top quality schools, health and safety, commute times, and more. The livability index, provided by Toronto, Canada-based data analytics and real estate platform AreaVibes, said Bellaire has "an abundance of exceptional local amenities."

"Among these are conveniently located grocery stores, charming coffee shops, diverse dining options and plenty of spacious parks," AreaVibes said. "These local amenities contribute significantly to its overall appeal, ensuring that [residents'] daily needs are met and offering ample opportunities for leisure and recreation."

Earlier in 2025, GoBankingRates ranked Bellaire as the No. 23 wealthiest suburb in America, and it's no stranger to being named on similar lists comparing the richest American cities.

How a Houston startup is taking on corrosion, a costly climate threat

now streaming

Corrosion is not something most people think about, but for Houston's industrial backbone pipelines, refineries, chemical plants, and water infrastructure, it is a silent and costly threat. Replacing damaged steel and overusing chemicals adds hundreds of millions of tons of carbon emissions every year. Despite the scale of the problem, corrosion detection has barely changed in decades.

In a recent episode of the Energy Tech Startups Podcast, Anwar Sadek, founder and CEO of Corrolytics, explained why the traditional approach is not working and how his team is delivering real-time visibility into one of the most overlooked challenges in the energy transition.

From Lab Insight to Industrial Breakthrough

Anwar began as a researcher studying how metals degrade and how microbes accelerate corrosion. He quickly noticed a major gap. Companies could detect the presence of microorganisms, but they could not tell whether those microbes were actually causing corrosion or how quickly the damage was happening. Most tests required shipping samples to a lab and waiting months for results, long after conditions inside the asset had changed.

That gap inspired Corrolytics' breakthrough. The company developed a portable, real-time electrochemical test that measures microbial corrosion activity directly from fluid samples. No invasive probes. No complex lab work. Just the immediate data operators can act on.

“It is like switching from film to digital photography,” Anwar says. “What used to take months now takes a couple of hours.”

Why Corrosion Matters in Houston's Energy Transition

Houston's energy transition is a blend of innovation and practicality. While the world builds new low-carbon systems, the region still depends on existing industrial infrastructure. Keeping those assets safe, efficient, and emission-conscious is essential.

This is where Corrolytics fits in. Every leak prevented, every pipeline protected, and every unnecessary gallon of biocide avoided reduces emissions and improves operational safety. The company is already seeing interest across oil and gas, petrochemicals, water and wastewater treatment, HVAC, industrial cooling, and biofuels. If fluids move through metal, microbial corrosion can occur, and Corrolytics can detect it.

Because microbes evolve quickly, slow testing methods simply cannot keep up. “By the time a company gets lab results, the environment has changed completely,” Anwar explains. “You cannot manage what you cannot measure.”

A Scientist Steps Into the CEO Role

Anwar did not plan to become a CEO. But through the National Science Foundation's ICorps program, he interviewed more than 300 industry stakeholders. Over 95 percent cited microbial corrosion as a major issue with no effective tool to address it. That validation pushed him to transform his research into a product.

Since then, Corrolytics has moved from prototype to real-world pilots in Brazil and Houston, with early partners already using the technology and some preparing to invest. Along the way, Anwar learned to lead teams, speak the language of industry, and guide the company through challenges. “When things go wrong, and they do, it is the CEO's job to steady the team,” he says.

Why Houston

Relocating to Houston accelerated everything. Customers, partners, advisors, and manufacturing talent are all here. For industrial and energy tech startups, Houston offers an ecosystem built for scale.

What's Next

Corrolytics is preparing for broader pilots, commercial partnerships, and team growth as it continues its fundraising efforts. For anyone focused on asset integrity, emissions reduction, or industrial innovation, this is a company to watch.
