If there is anything that goes hand in hand so perfectly, it's Houston and Space. Houston is home to the Johnson Space Center, named after former president Lyndon B. Johnson, and is home to revolutionary space research projects and spaceflight training for both crew members and flight controllers. While it's every kid's dream to become an astronaut, have you ever wondered why rocket science is actually so difficult?

Though the space race of the '70s has been over for some time, the new space race — the race to Mars and the commercialization of space tourism — has just started. Elon Musk, Jeff Bezos, and Richard Branson are spearheading the "Billionaire space race." But even with their billions being put into developing spaceports, NASA rocket partnerships, and planning future Mars missions, rocket science is just as difficult to implement as it was the first time around.

So why, even with billions of dollars at their disposal and many companies pushing for more funding, are scientists and engineers still struggling to make rocket travel an everyday thing? Here are some of the countless reasons why rockets science is insanely difficult, no matter how much money you throw at it.

Small talent pool

The Apollo astronauts were the best of the best — and the hundreds of thousands of engineers and rocket scientists behind the scenes were just as talented. But getting to the point in one's career where you have the right background experience and the right hands-on work and real-life experience to create a safe rocket is difficult. The talent pool that SpaceX, Virgin Galactic, and Blue Origin are working with is extremely small and notoriously competitive. As these programs continue to build in credibility, it may be easier to find talent, but few engineers want to be tied to a failed launch.

The risk of failure

Usually, when you fail at something like a math test or a driver's exam, the ramifications aren't too big. But with space travel, a small problem can quickly turn into a deadly situation for those on board the rocket. Think back to the Challenger explosion in 1986. The success of previous missions (not to mention the administrative corner-cutting) led to a false sense of security when in reality they were still embarking on the insanely difficult feat of launching humans into space. The risk of failure is so great, many commercial manufacturers are cautious to put their weight behind an operation that could in all likelihood come crashing back down to Earth.

Rocket construction

Think back to when you were in school learning about Isaac Newton's Third Law of Motion: for every action, there is an equal and opposite reaction. It's a simple idea, but complex in reality. That law of motion forms the basis for rocket science: the combustion of rocket fuel down into the earth is one action, so the opposite reaction causes the rocket to launch upward into space. But the engineering that's needed for a launch to take place is the hard part.

As mentioned in a 2012 NPR article, there are millions of pieces in every rocket, and "therefore millions of opportunities to make errors — to make errors in calculations, to make errors in construction." The devastating Challenger mission failure is often attributed to faulty O-rings — it's a simple piece of equipment and can often be overlooked.

Even after hundreds of successful launches over the years, rocket construction is just as complex, and the process of shooting humans into space cannot be distilled to a law of motion when there is so much more involved to make that process happen.

Public perception

Throughout the '70s, Americans were enthralled by the idea of the space race and becoming the first country to set foot on the moon. But the public's passion died down after that initial landing. Today, the public perception of current space projects is making doing the actual rocket science and engineering difficult.


Objections against NASA's waste of taxpayer money on "futile" missions and the idea that space travel will only be for the mega-wealthy make any conversation around actual scientific discovery second to politics. Not to even mention the newly minted Space Force. Engineers and scientists have to navigate a hoard of political, financial, and PR battles to even get to do the work of getting people back into space.

The bottom line

Rocket science is thought of as one of the most difficult fields for a reason. Building a piece of technology capable of going into space and even housing people inside is a relatively new feat when considering the span of time. As the billionaire space race continues to unfold, scientists and engineers behind the scenes are creating feats of engineering on a regular basis that will shape the future of space travel. But, if you want to just get a taste of space life, without all the schooling, then a trip to the Johnson Space Center is for you.

Texas Space Commission doles out $5.8 million to Houston companies

On A Mission

Two Houston-area companies have landed more than $5.8 million in funding from the Texas Space Commission.

The commission granted up to $5.5 million to Houston-based Axiom Space and up to $347,196 to Conroe-based FluxWorks.

The two-year-old commission previously awarded $95.3 million to 14 projects. A little over $34 million remains in the commission-managed Space Exploration and Aeronautics Research Fund.

Axiom Space, a commercial spaceflight company, said the new funding will go toward the development of its orbital data center capabilities. By the end of this year, Axiom plans to launch two free-flying nodes in low-Earth orbit to support its orbital data center operations. More nodes are set to go online in the coming years.

“Axiom Space is actively evaluating how our [orbital data center] architecture can enhance critical U.S. capabilities, including the proposed Golden Dome missile defense architecture,” Jason Aspiotis, global director of in-space data and security at Axiom, said in a news release. “In this context, real-time, around-the-clock availability, secure orbital processing, and AI-driven autonomy are vital for ensuring mission success.”

Founded in 2021, FluxWorks provides magnetic gear technology that was developed at Texas A&M University.

In 2024, FluxWorks 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), which manages the International Space Station National Laboratory.

FluxWorks is testing the performance of magnetic gear in microgravity environments, such as the International Space Station.

“Gearboxes aim to reduce the mass of motors required in a variety of applications; however, the lubricant needed to make them work properly is not designed for use in extreme environments like space,” according to a 2024 news release about the Technology in Space Prize. “Magnetic gears do not require lubricant, making them an appealing alternative.”

The Texas Space Commission granted $25 million to Houston aerospace companies Starlab Space and Intuitive Machines earlier this year. Read more here.

3 Houston startups named most innovative in Texas by LexisNexis

report card

Three Houston companies claimed spots on LexisNexis's 10 Most Innovative Startups in Texas report, with two working in the geothermal energy space.

Sage Geosystems claimed the No. 3 spot on the list, and Fervo Energy followed closely behind at No. 5. Fintech unicorn HighRadius rounded out the list of Houston companies at No. 8.

LexisNexis Intellectual Property Solutions compiled the report. It was based on each company's Patent Asset Index, a proprietary metric from LexisNexis that identifies the strength and value of each company’s patent assets based on factors such as patent quality, geographic scope and size of the portfolio.

Houston tied with Austin, each with three companies represented on the list. Caris Life Sciences, a biotechnology company based in Dallas, claimed the top spot with a Patent Asset Index more than 5 times that of its next competitor, Apptronik, an Austin-based AI-powered humanoid robotics company.

“Texas has always been fertile ground for bold entrepreneurs, and these innovative startups carry that tradition forward with strong businesses based on outstanding patent assets,” Marco Richter, senior director of IP analytics and strategy for LexisNexis Intellectual Property Solutions, said in a release. “These companies have proven their innovation by creating the most valuable patent portfolios in a state that’s known for game-changing inventions and cutting-edge technologies.We are pleased to recognize Texas’ most innovative startups for turning their ideas into patented innovations and look forward to watching them scale, disrupt, and thrive on the foundation they’ve laid today.”

This year's list reflects a range in location and industry. Here's the full list of LexisNexis' 10 Most Innovative Startups in Texas, ranked by patent portfolios.

  1. Caris (Dallas)
  2. Apptronik (Austin)
  3. Sage Geosystems (Houston)
  4. HiddenLayer (Austin)
  5. Fervo Energy (Houston)
  6. Plus One Robotics (San Antonio)
  7. Diligent Robotics (Austin)
  8. HighRadius (Houston)
  9. LTK (Dallas)
  10. Eagle Eye Networks (Austin)

Sage Geosystems has partnered on major geothermal projects with the United States Department of Defense's Defense Innovation Unit, the U.S. Air Force and Meta Platforms. Sage's 3-megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, was expected to be completed by the end of last year.

Fervo Energy fully contracted its flagship 500 MW geothermal development, Cape Station, this spring. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026. The company was recently named North American Company of the Year by research and consulting firm Cleantech Group and came in at No. 6 on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025. It's now considered a unicorn, meaning its valuation as a private company has surpassed $1 billion.

Meanwhile, HighRadius announced earlier this year that it plans to release a fully autonomous finance platform for the "office of the CFO" by 2027. The company reached unicorn status in 2020.

UH student earns prestigious award for cancer vaccine research

up-and-comer

Cole Woody, a biology major in the College of Natural Sciences and Mathematics at the University of Houston, has been awarded a Barry Goldwater Scholarship, becoming the first sophomore in UH history to earn the prestigious prize for research in natural sciences, mathematics and engineering.

Woody was recognized for his research on developing potential cancer vaccines through chimeric RNAs. The work specifically investigates how a vaccine can more aggressively target cancers.

Woody developed the MHCole Pipeline, a bioinformatic tool that predicts peptide-HLA binding affinities with nearly 100 percent improvement in data processing efficiency. The MHCole Pipeline aims to find cancer-specific targets and develop personalized vaccines. Woody is also a junior research associate at the UH Sequencing Core and works in Dr. Steven Hsesheng Lin’s lab at MD Anderson Cancer Center.

“Cole’s work ethic and dedication are unmatched,” Preethi Gunaratne, director of the UH Sequencing Core and professor of Biology & Biochemistry at NSM, said in a news release. “He consistently worked 60 to 70 hours a week, committing himself to learning new techniques and coding the MHCole pipeline.”

Woody plans to earn his MD-PhD and has been accepted into the Harvard/MIT MD-PhD Early Access to Research Training (HEART) program. According to UH, recipients of the Goldwater Scholarship often go on to win various nationally prestigious awards.

"Cole’s ability to independently design and implement such a transformative tool at such an early stage in his career demonstrates his exceptional technical acumen and creative problem-solving skills, which should go a long way towards a promising career in immuno-oncology,” Gunaratne added in the release.
