It's no secret that Austin and San Antonio are becoming some of the biggest cities in Texas, and that together, they just might rival the likes of Houston and Dallas-Fort Worth one day.

A new documentary called San Antonio-Austin: The Emerging Mega-Metro takes a deep dive into the booming 80-mile region between the Central Texas cities

Produced by KLRN, San Antonio's local PBS station, the program centers on the region's growth and the challenges that arise with such rapid expansion, such as water scarcity, environmental impacts, and increasingly common transportation and traffic woes.

They're issues that Houston residents know well, as the city's population continues to explode at a staggering rate.

"We know the area between San Antonio and Austin is growing at a tremendously rapid pace, but what is really happening is the development of a mega-metro that will be one of the biggest economic powerhouses in the world," says Shari St. Clair, the documentary's executive producer, in a release.

“We delve into the questions that need to be asked right now — how do we retain quality of life as we grow? How do we build a sustainable workforce?" St. Clair continues. "And, can San Antonio and Austin truly join forces and work together to make the most of this incredible opportunity?"

The hour-long documentary is hosted by former San Antonio mayor Henry Cisneros, who also authored The Texas Triangle: An Emerging Power in the Global Economy. The special highlights several prominent Central Texas leaders, including interviews with Austin Mayor Kirk Watson, San Antonio Mayor Ron Nirenburg, U.S. Congressman Greg Casar, and more.

As Texas is also a state of committed sports fans, the idea of a mega-metro between Austin and San Antonio is additionally explored through a sports lens. The documentary interviewed legends like Nolan Ryan, Sean Elliot, and Spurs Chairman Peter J. Holt.

In the latest chapter in the saga of the high-speed bullet train between Houston and Dallas, Amtrak is now involved.

According to a press release, Texas Central Partners and Amtrak are exploring a partnership to work together on the proposed Dallas-Houston high-speed rail project that's been under consideration for more than a decade.

Amtrak has cooperated with Texas Central on various initiatives since 2016 and the two entities are now evaluating a potential partnership to determine the line's viability.

“If we are going to add more high-speed rail to this country, the Dallas to Houston Corridor is a compelling proposition and offers great potential,” says Amtrak senior VP of High-Speed Rail Development Programs Andy Byford. “We believe many of the country's biggest and fastest-growing metropolitan areas, like Houston and Dallas, deserve more high quality high-speed, intercity rail service, and we are proud to bring our experience to evaluate this potential project and explore opportunities with Texas Central so the state can meet its full transportation needs.”

The route being proposed would span approximately 240 miles, going at 250 mph, resulting in a trip that would take less than 90 minutes between the two cities.

Texas Central has been working towards getting a train rolling since 2013, including lining up a potential builder in 2021. But the project has had pushback from Texas politicians and landowners along the route; a lawsuit against the project was filed by six rural counties in 2021, and the Texas Legislature passed a law prohibiting the state from spending any funds on the project.

Facing a seeming dead end, Texas Central CEO Carlos Aguilar and its board members resigned in June 2022; Michael Bui, a consultant, has been serving as CEO since then.

Texas Central and Amtrak have submitted applications to several federal programs in connection with further study and design work, including the Consolidated Rail Infrastructure Safety and Improvements (CRISI) grant program, the Corridor Identification and Development program, and the Federal-State Partnership for Intercity Passenger Rail (FSP-National) grant program.

Amtrak previously entered into an agreement with Texas Central to provide through-ticketing using the Amtrak reservation system and other support services for the planned high-speed rail line.

"This high-speed train, using advanced, proven Shinkansen technology, has the opportunity to revolutionize rail travel in the southern U.S., and we believe Amtrak could be the perfect partner to help us achieve that,” says Bui in a statement.

Despite its detractors, the project is forecast to provide social, environmental, employment and economic benefits including reducing greenhouse gas emissions by more than 100,000 tons per year, saving 65 million gallons of fuel and removing 12,500 cars per day from I-45.

The release from Amtrak has statements from both Dallas Mayor Eric L. Johnson and Houston Mayor Sylvester Turner, who calls the collaboration between Texas Central and Amtrak "an important milestone for the City of Houston and this project."

Byford joined Amtrak in April 2023 to begin developing a team focused on high-speed opportunities throughout the U.S. In his newly created role, he will develop and lead the execution of Amtrak’s long-term strategy for high-speed rail throughout the country, including the extension of the Crescent from Mississippi through Louisiana and Texas; Kansas DOT’s Heartland Flyer Extension Corridor Identification and Development (Corridor ID) connecting Wichita to Oklahoma and Texas, and TxDOT’s applications for the Texas Triangle (Houston — Dallas – Fort Worth – San Antonio) routes.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
