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.”

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

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

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.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
