NASA tapped Joe Acaba as its chief of the Astronaut Office based in Johnson Space Center in Houston. He's served on multiple spaceflights and is a former U.S. Marine and former educator. According to NASA, he's the first person of Hispanic heritage selected to lead the office.

Acaba replaces Drew Feustel, who spent two years as deputy chief and has been acting chief of the office since NASA astronaut Reid Wiseman left the post late last year.

"Joe is an experienced space flyer and a proven leader, and he will undoubtedly inspire the next generation of NASA astronauts," says NASA Administrator Bill Nelson in a news release. " As we build on the International Space Station’s unparalleled success in low-Earth orbit with our eyes on the Moon and then Mars, Joe will play an integral role in ensuring our NASA astronauts are prepared for the challenges ahead."

Acaba, who spent a total of 306 days in space, has already supported the astronaut office in a few of roles, including director of operations in Russia and chief of the Vehicle Integration Test Office. In this new role, he will be oversee astronaut resources and operations and help develop astronaut flight crew operation concepts. Additionally, Acaba will make crew assignments for future spaceflight missions, including astronauts assigned to fly on Artemis missions.

“Our Johnson Space Center team congratulates Joe Acaba on his selection to chief of the Astronaut Office. We wish him well as he takes on this new and exciting leadership role,” says NASA Johnson Space Center Director Vanessa Wyche.

Virtual reality studio HTX Labs has named Bob Kleinhample as the company’s senior vice president of growth. He has more than 15 years leading business efforts in the tech space. A 20-year Army veteran, Kleinhample will oversee all aspects of HTX Labs' growth — including business development, product strategy, and marketing.

“Bob brings the right balance of market knowledge and product strategy, in combination with the commitment to bring immersive training and simulation to the warfighter, to really drive our EMPACT offering into the market,” says Scott Schneider, CEO and co-founder of HTX Labs. "We’re very excited to be adding this incredibly important role to our organization and having Bob lead these efforts as we expand the usage and adoption of EMPACT across the Department of Defense."

The appointment comes after the startup raised $3.2 million in its first outside capital round.

“Last year we secured funding from Cypress Growth Capital for the sole purpose of accelerating the growth of our EMPACT platform and our customer base, and we immediately began a search for the right person to lead these growth efforts," Schneider continues. "After performing an extensive search, we are fortunate to have connected with Bob Kleinhample who is coming on board to lead our company’s growth efforts“.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

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."
