Houston space tech company reaches major milestone for engine technology

fired up

A Houston company that's creating the next generation of space exploration technology is celebrating a new milestone of one of its technologies.

Intuitive Machines reports that its VR900 completed a full-duration hot-fire test, qualifying it for its IM-2 lunar mission. With the qualification, the company says its VR3500, an engine designed for larger cargo class landers, also advances in development.

The engine technology is designed, 3D-printed, and tested all at Intuitive Machines' Houston facility, which opened in the Houston Spaceport last year.

Intuitive Machines CEO Steve Altemus says in a news release that the company's goal was to lead the way in scalable deep space engines as the industry heads toward lunar missions.

“This validated engine design meets current mission demand and paves the way for our VR3500 engine for cargo delivery such as lunar terrain vehicles, human spaceflight cargo resupply, and other infrastructure delivery," Altemus continues. "We believe we’re in a prime position to build on our successful development and apply that technology toward current contracts and future lunar requirements for infrastructure delivery.”

Earlier this year, Intuitive Machines was one of one of three companies selected for a $30 million NASA contract for the initial phase of developing a rover for U.S. astronauts to traverse the moon’s surface.

Another Houston company has seen success with its engine testing. In March, Venus Aerospace announced that it's successfully ran the first long-duration engine test of their Rotating Detonation Rocket Engine in partnership with Defense Advanced Research Projects Agency, or DARPA.

ready for liftoff

Since the Houston Spaceport secured the 10th FAA-Licensed commercial spaceport designation in 2015, the development's tenants have gone on to secure billions in NASA contracts. Now, the Houston Spaceport is on to its next phase of growth.

“Reflecting on its meteoric rise, the Spaceport has seen remarkable growth in a short span of time. From concepts on paper to the opening of Axiom Space, Collins Aerospace, and Intuitive Machines, the journey has been nothing short of extraordinary,” says Arturo Machuca, director of Ellington Airport and the Houston Spaceport, in a news release. “These anchor tenants, collectively holding about $5 billion in contracts with NASA and other notable aerospace companies, are not just shaping the future of space exploration but injecting vitality into Houston’s economy.”

The next phase of development, according to Houston Airports, will include:

  • The construction of a taxiway to connect Ellington Airport and the Spaceport
  • The construction of a roadway linking Phase 1 infrastructure to Highway 3
  • The expansion of the EDGE Center, in partnership with San Jacinto College

Rendering via Houston Airports

The Houston Spaceport's first phase completed in 2019. Over the past few years, tenants delivered on their own buildouts. Last year, Intuitive Machines moved into its new $40 million headquarters and Axiom Space opened its test facility. In 2022, Collins Aerospace cut the ribbon on its new 120,000 square-foot facility.

“The vision for the Houston Spaceport has always been ambitious,” says Jim Szczesniak, director of Aviation for Houston Airports. “Our vision is to create a hub for aviation and aerospace enterprises that will shape the future of commercial spaceflight.”

Educational partners have also revealed new spaces, including San Jacinto College's EDGE Center, which broke ground in July of 2019, finally celebrated its grand opening in 2021. Last year, Texas Southern University got the greenlight to operate an aeronautical training hub on a two-acre site at Ellington Airport.

“By providing the education and training needed to sustain jobs in the rapidly evolving space industry, the Spaceport is not only attracting companies but also nurturing the talent that will drive Houston's aerospace sector forward,” continues Szczesniak in the release.

taking flight

A Houston tech company working on an engine to enable hypersonic flights has reported its latest milestone.

Venus Aerospace announced that it's successfully ran the first long-duration engine test of their Rotating Detonation Rocket Engine in partnership with Defense Advanced Research Projects Agency, or DARPA.

The RDRE engine Venus is working on is uniquely designed and a first in the field. It has an additional 15 percent efficiency over traditional rocket engines.

"As we continue to push towards our ultimate mission of high-speed global flight, this is an important technical milestone for having a flight-ready engine," Andrew Duggleby, CTO and co-founder of Venus Aerospace, says in the news release. "I'm incredibly proud of our team as they continue to push forward on this world-changing technology."

The test results are a big win, as the RDRE had previously only been tested in a short-duration capacity. DARPA is just one of several U.S. Government agencies that has contracts with Venus.

"The successful test is a testament to our team's dedication and expertise. We're building something special here at Venus, in large part because we have the right people and the right partners," Sassie Duggleby, CEO and co-founder of Venus Aerospace, adds. "I can't say enough about our collaboration with DARPA and the role they played in helping us make this leap forward."

Last summer, Venus added a new investor to its cap table. Andrew Duggleby founded Venus Aerospace with his wife and CEO Sassie in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round. Sassie joined the Houston Innovators Podcast a year ago to explain her company's mission of "home for dinner."

They are also developing its successor, Axiom Station, and building next-generation spacesuits for the moon, low-Earth orbit, and other missions. The company describes itself as “the leading provider of human spaceflight services and developer of human-rated space infrastructure.”

Axiom joins Collins Aerospace and Intuitive Machines as the three tenants of the Houston Spaceport, which is an FAA-licensed, urban commercial spaceport for the aerospace community. Intuitive Machines supports NASA’s $93 billion Artemis program, which aims to return astronauts to the moon by 2024 and eventually send humans to Mars.

“Today’s celebration is the culmination of teamwork and tenacity, and it underscores a year of historic milestones for Houston Airports,” Mario Diaz, director of Aviation for Houston Airports, says in a news release. “It’s not enough that we operate world-class airports, Houston Airports must also endeavor to progress humanity’s reach out into space. Axiom space solidifies this unique urban center for collaboration and ideation. A place where the brightest minds in the world work closely together to lead us beyond the next frontier of space exploration.”

The Houston Spaceport Development Corp. received $5 million from funds administered by the Governor's Office of Economic Development and Tourism. Axiom Space is valued at $1 billion as of earlier this year, according to Bloomberg. Axiom joins Intuitive Machines, which opened its new Houston Spaceport headquarters earlier this year.

Texas plugs in among states at highest risk for summer power outages in 2025

hot, hot, hot

Warning: Houston could be in for an especially uncomfortable summer.

A new study from solar energy company Wolf River Electric puts Texas at No. 2 among the states most at risk for power outages this summer. Michigan tops the list.

Wolf River Electric analyzed the number of large-scale outages that left more than 5,000 utility customers, including homes, stores and schools, without summertime electricity from 2019 to 2023. During that period, Texas experienced 7,164 summertime power outages.

Despite Michigan being hit with more summertime outages, Texas led the list of states with the most hours of summertime power outages — an annual average of 35,440. That works out to 1,477 days. “This means power cuts in Texas tend to last longer, making summer especially tough for residents and businesses,” the study says.

The Electric Reliability Council of Texas (ERCOT), which operates the electric grid serving 90 percent of the state, predicts its system will set a monthly record for peak demand this August — 85,759 megawatts. That would exceed the current record of 85,508 megawatts, dating back to August 2023.

In 2025, natural gas will account for 37.7 percent of ERCOT’s summertime power-generating capacity, followed by wind (22.9 percent) and solar (19 percent), according to an ERCOT fact sheet.

This year, ERCOT expects four months to surpass peak demand of 80,000 megawatts:

  • June 2025 — 82,243 megawatts
  • July 2025 — 84,103 megawatts
  • August 2025 — 85,759 megawatts
  • September 2025 — 80,773 megawatts

One megawatt is enough power to serve about 250 residential customers amid peak demand, according to ERCOT. Using that figure, the projected peak of 85,759 megawatts in August would supply enough power to serve more than 21.4 million residential customers in Texas.

Data centers, artificial intelligence and population growth are driving up power demand in Texas, straining the ERCOT grid. In January, ERCOT laid out a nearly $33 billion plan to boost power transmission capabilities in its service area.

Houston ranks among top 5 cities for corporate HQ relocations in new report

h-town HQ

The Houston area already holds the title as the country’s third biggest metro hub for Fortune 500 headquarters, behind the New York City and Chicago areas. Now, Houston can tout another HQ accolade: It’s in a fourth-place tie with the Phoenix area for the most corporate headquarters relocations from 2018 to 2024.

During that period, the Houston and Phoenix areas each attracted 31 corporate headquarters, according to new research from commercial real estate services company CBRE. CBRE’s list encompasses public announcements from companies across various sizes and industries about relocating their corporate headquarters within the U.S.

Of the markets included in CBRE’s study, Dallas ranked first for corporate relocations (100) from 2018 to 2024. It’s followed by Austin (81), Nashville (35), Houston and Phoenix (31 each), and Denver (23).

According to CBRE, reasons cited by companies for moving their headquarters include:

  • Access to lower taxes
  • Availability of tax incentives
  • Proximity to key markets
  • Ability to support hybrid work

“Corporations now view headquarters locations as strategic assets, allowing for adaptability and faster reaction to market changes,” said CBRE.

Among the high-profile companies that moved their headquarters to the Houston area from 2018 to 2024 are:

  • Chevron
  • ExxonMobil
  • Hewlett-Packard Enterprise
  • Murphy Oil

Many companies that have shifted their headquarters to the Houston area, such as Chevron, are in the energy sector.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, said in 2024. “With deep roots in our region, Chevron is a key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

According to CBRE, California (particularly the San Francisco Bay and Los Angeles areas) lost the most corporate HQs in 2024, with 17 companies announcing relocations—12 of them to Texas. Also last year, Texas gained nearly half of all state-to-state relocations.

In March, Site Selection magazine awarded Texas its 2024 Governor’s Cup, resulting in 13 consecutive wins for the state with the most corporate relocations and expansions.

In a news release promoting the latest Governor’s Cup victory, Gov. Greg Abbott hailed Texas as “the headquarters of headquarters.”

“Texas partners with the businesses that come to our great state to grow,” Abbott said. “When businesses succeed, Texas succeeds.”

CBRE explained that the trend of corporate HQ relocations reflects the desire of companies to seek new environments to support their goals and workforce needs.

“Ultimately, companies are seeking to establish themselves in locations with potential for long-term success and profitability,” CBRE said.

SpaceX test rocket explodes in Texas, but no injuries reported

SpaceX Update

A SpaceX rocket being tested in Texas exploded Wednesday night, sending a dramatic fireball high into the sky.

The company said the Starship “experienced a major anomaly” at about 11 pm while on the test stand preparing for the 10th flight test at Starbase, SpaceX’s launch site at the southern tip of Texas.

“A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,” SpaceX said in a statement on the social platform X.

CEO Elon Musk ’s SpaceX said there were no hazards to nearby communities. It asked people not to try to approach the site.

The company said it is working with local officials to respond to the explosion.

The explosion comes on the heels of an out-of-control Starship test flight in late May, which tumbled out of control. The FAA demanded an investigation into the accident.
