A Houston organization announced that it plans to launch six more experiments into space next year that look to learn more about everything from motion sickness to genome alterations during space travel.

The Translational Research Institute for Space Health, or TRISH, which is part of BCM’s Center for Space Medicine, will team up once more with Houston-based Axiom Space on its third private astronaut mission to the International Space Station, Ax-3, which is expected to launch in January. TRISH also sent experiments on Axiom's Ax-2 mission that launched in May.

The experiments are part of TRISH's Enhancing eXploration Platforms and Analog Definition (EXPAND) program, which aims "to help humans thrive on future space missions," according to a release.

“Our commercial spaceflight partners such as Axiom Space are instrumental to cutting-edge research, including these projects designed to reveal how the human body and mind function in the extreme environment of space,” Dr. Emmanuel Urquieta, TRISH chief medical officer, EXPAND program lead and assistant professor in the Center for Space Medicine at Baylor. “This work represents an important step in our journey to understand the body's response to challenging conditions, which is critical for improving human health both here on Earth and on future long-duration missions, including to the Moon and Mars.”

The six project onboard Ax-3 include:

  • Cognitive and Physiologic Responses in Commercial Space Crew on Short-Duration Missions, Mathias Basner, M.D., Ph.D., M.S., University of Pennsylvania Perelman School of Medicine: Basner’s team will track spaceflight participants’ memory, abstraction, spatial orientation, emotion recognition, risk decision-making and sustained attention before and after space travel
  • Otolith and Posture Evaluation II, Mark Shelhamer, Sc.D., Johns Hopkins University: Shelhamer's team will study how inner ears and eyes sense and respond to motion before and immediately after spaceflight to predict who is likely to develop space motion sickness.
  • Space Omics + BioBank, Richard Gibbs, Ph.D., Baylor College of Medicine: Gibbs’ team will gather biological specimens from astronauts before and after their mission to assess the effects of spaceflight on the human body at the genomic level.
  • SANS Surveillance, TRISH: The institute will study Spaceflight Associated Neuro-Ocular Syndrome by collecting vision function data during the ground phases of the mission.
  • Standardized research questionnaires, TRISH: The institute will gather contextual and qualitative data points for its EXPAND research database related to sleep, personality, health history, team dynamics and immune-related symptoms.
  • Sensorimotor adaptation, TRISH: The institute will collect data on how spaceflight participants' ability to stand, balance and have full body control.

Ax-3 is Axiom's third commercial astronaut mission to the ISS, which the company announced in March. The crew, which includes Commander Michael López-Alegría, Pilot Walter Villadei, and Mission Specialists Alper Gezeravcı and Marcus Wandt, will spend 14 days on the ISS. The mission will launch from NASA’s Kennedy Space Center in Florida aboard a SpaceX Dragon spacecraft.

Axiom also has plans for its fourth private mission, Ax-4, which it announced in August.

In addition to the partnership with Axiom, TRISH also announced late last month that it has made a new agreement with the Australian Antarctic Division's Polar Medicine Unit. The collaboration will nominate pilot projects that focus on challenges associated with extreme isolation, which have applications in long-duration space travel to the Moon and Mars.

“Our international collaboration with the AAD will extract insights to benefit all future astronauts, as well as other explorers of extreme environments,” said Dr. Dorit Donoviel, associate professor in the Center for Space Medicine at Baylor and TRISH executive director. “This agreement marks the beginning of yet another exciting venture into space health research for TRISH, and we look forward to collaborating with the AAD to advance our shared goal of promoting safe human exploration.”

In March, TRISH also announced an international agreement with the Korea National Institute of Health. The two organizations plan to collaborate on research related to mental health issues due to space travel, the challenges of food supply in deep space, the negative effects of space radiation and en-suite medical care for long-duration space travel.

TRISH is also slated to launch nine experiments on board SpaceX's Polaris Dawn mission, which is now expected to launch no earlier than 2024. The research aboard Polaris Dawn is intended to complement research supported by TRISH on the Inspiration4 all-civilian mission to orbit.

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.”
