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.

Houston space tech startup reports milestone achievement in partnership with federal agency

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."

Axiom Space has set itself apart from others in the private space industry. Our city – Space City — is leading this second space race. And the work being done in our city will return humanity to the moon in a sustainable way.”

Axiom operates end-to-end missions to the International Space Station. 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.

Houston space tech startups share latest updates on lunar missions and more

space update

Houston-based space tech companies Axiom Space and Intuitive Machines recently shared updates on innovative projects and missions, each set to launch by 2027.

Axiom Space

Axiom Space, developer of the world’s first commercial space station and other space infrastructure, is gearing up to launch two orbital data center nodes to low-earth orbit by the end of 2025.

The Axiom Space nodes will lay the foundation for space-based cloud computing. Axiom says orbital data centers provide cloud-enabled data storage and processing, artificial intelligence, and machine learning directly to satellites, constellations, and other spacecraft in Earth’s orbit. This innovation will reduce reliance on earth-based systems, enhance wireless mesh networks and improve real-time operation of space-borne assets, according to Axiom.

Axiom has been working on the development of orbital data centers since 2022. The two nodes going into space in 2025 will be part of Kepler Communications’ 10-satellite data relay network, which is scheduled to launch by the end of this year. Axiom Space and Kepler Communications have been collaborating since 2023.

Kam Ghaffarian, co-founder, executive chairman, and CEO of Axiom, says his company already has deals in place with buyers of space-based cloud computing services. Orbital data centers “are integral to Axiom Space’s vision of era-defining space infrastructure, unlocking transformational capabilities and economic growth,” he says.

Axiom Space says it will be able to buy additional payloads on Kepler’s network to boost capacity for orbital data centers. The two companies will team up to provide network and orbital data center services to various customers.

Intuitive Machines

Meanwhile, Intuitive Machines, a space exploration, infrastructure and services company, has picked SpaceX’s Falcon 9 rocket to launch its fourth delivery mission to the moon. The launch will include two lunar data relay satellites for NASA.

Intuitive Machines says its fourth lunar delivery mission is scheduled for 2027. The mission will comprise six NASA commercial lunar payloads, including a European Space Agency drill set designed to search for water at the moon’s south pole.

“Lunar surface delivery and data relay satellites are central to our strategy to commercialize the moon,” Intuitive Machines CEO Steve Altemus says.

The first of five lunar data relay satellites will be included in the company’s third delivery mission to the moon. The fourth mission, featuring two more satellites, will be followed by two other satellite-delivery missions.

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.
