NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.

Innovative Houston-area hardtech startup closes $5M seed round

fresh funding

Conroe-based hardtech startup FluxWorks has closed a $5 million seed round.

The funding was led by Austin-based Scout Ventures, which invests in early-stage startups working to solve national security challenges.

Michigan Capital Network also contributed to the round from its MCN Venture Fund V. The fund is one of 18 selected by the Department of Defense and Small Business Administration to participate in the Small Business Investment Company Critical Technologies Initiative, which will invest $4 billion into over 1,700 portfolio companies.

FluxWorks reports that it will use the funding to drive the commercialization of its flagship Celestial Gear technology.

"At Scout, we invest in 'frontier tech' that is essential to national interest. FluxWorks is doing exactly that by solving critical hardware bottlenecks with its flagship Celestial Gear technology ... This is about more than just gears; it’s about strengthening our industrial infrastructure," Scout Ventures shared in a LinkedIn post.

Fluxworks specializes in making contactless magnetic gears for use in extreme conditions, which can enhance in-space manufacturing. Its contactless design leads to less wear, debris and maintenance. Its technology is particularly suited for space applications because it does not require lubricants, which can be difficult to control at harsh temperatures and in microgravity.

The company received a grant from the Texas Space Commission last year and was one of two startups to receive the Technology in Space Prize, funded by Boeing and the Center for the Advancement of Science in Space (CASIS), in 2024. It also landed $1.2 million through the National Science Foundation's SBIR Phase II grant this fall.

Fluxworks was founded in College Station by CEO Bryton Praslicka in 2021. Praslicka moved the company to Conroe 2024.

Investment bank opens new Houston office focused on energy sector

Investment bank Cohen & Co. Capital Markets has opened a Houston office to serve as the hub of its energy advisory business and has tapped investment banking veteran Rahul Jasuja as the office’s leader.

Jasuja joined Cohen & Co. Capital Markets, a subsidiary of financial services company Cohen & Co., as managing director, and head of energy and energy transition investment banking. Cohen’s capital markets arm closed $44 billion worth of deals last year.

Jasuja previously worked at energy-focused Houston investment bank Mast Capital Advisors, where he was managing director of investment banking. Before Mast Capital, Jasuja was director of energy investment banking in the Houston office of Wells Fargo Securities.

“Meeting rising [energy] demand will require disciplined capital allocation across traditional energy, sustainable fuels, and firm, dispatchable solutions such as nuclear and geothermal,” Jasuja said in a news release. “Houston remains the center of gravity where capital, operating expertise, and execution come together to make that transition investable.”

The Houston office will focus on four energy verticals:

  • Energy systems such as nuclear and geothermal
  • Energy supply chains
  • Energy-transition fuel and technology
  • Traditional energy
“We are making a committed investment in Houston because we believe the infrastructure powering AI, defense, and energy transition — from nuclear to rare-earth technology — represents the next secular cycle of value creation,” Jerry Serowik, head of Cohen & Co. Capital Markets, added in the release.
