Houston, we're trying to fix the problem: Aerospace challenges and future exploration

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 cybersecurity co. expands unique train-to-hire model to Houston

job search

It’s increasingly more difficult to ensure the confidentiality, integrity, and availability of proprietary data and information in the ever-changing, ever-evolving digital world.

Cyberattacks, including malware, phishing, and ransomware, are becoming increasingly common and sophisticated, posing a consistent threat to a company’s sustainability and bottom line.

To combat that trend, Nukudo, a San Antonio-based cybersecurity workforce development company, is expanding its initiative to bridge the global cybersecurity talent gap through immersive training and job placement to Houston.

“We saw that there was a need in the market because there's a shortage of skilled manpower within the cybersecurity industry and other digital domains,” says Dean Gefen, CEO of NukuDo. “So, our initial goal was to take a large pool of people and then make them to be fully operational in cybersecurity in the shortest amount of time.”

The company refers to the plan as the “training-to-employment model,” which focuses on providing structured training to select individuals who then acquire the skills and knowledge necessary to secure and maintain fruitful careers.

The company identifies potential associates through its proprietary aptitude test, which recognizes individuals who possess the innate technical acumen and potential for success in various cybersecurity roles, regardless of their level of education.

“We take in people from all walks of life, meaning the program is purely based on the associate’s potential,” Gefen says. “We have people who were previously aircraft engineers, teachers, graphic designers, lawyers, insurance agents and so forth.”

Once selected, associates are trained by cybersecurity experts while gaining hands-on experience through scenario-based learning, enabling them to be deployed immediately as fully operational cybersecurity professionals.

The program training lasts just six months—all paid—followed by three years of guaranteed employment with NukuDo.

While in training, associates are paid $ 4,000 per month; then, they’re compensated by nearly double that amount over the next three years, ultimately pushing their salaries to well into the six figures after completing the entire commitment.

In addition to fostering a diverse talent pipeline in the cybersecurity field, NukuDo is creating a comprehensive solution to address the growing shortage of technical talent in the global workforce.

And arming people with new marketable skills has a litany of benefits, both professional and personal, Gefen says.

“Sometimes, we have associates who go on to make five times their previous salary,” says Gefen. “Add to that fact that we had someone that had a very difficult life beforehand and we were able to put him on a different path. That really hits home for us that we are making a difference.

Nulkudo currently has partnerships with companies such as Accenture Singapore and Singapore Airlines. Gefen says he and his team plans to have a new class of associates begin training every month by next year and take the model to the Texas Triangle (Houston, Austin and Dallas)—then possibly nationwide.

“The great thing about our program is that we train people above the level of possible threat of replacement by artificial intelligence,” Gefen says. “But what we are also doing, and this is due to requirements that we have received from clients that are already hiring our cyber professionals, is that we are now starting to deliver AI engineers and data scientists in other domains.”

“That means that we have added more programs to our cybersecurity program. So, we're also training people in data science and machine learning,” he continues.

All interested candidates for the program should be aware that a college degree is not required. NukuDo is genuinely interested in talented individuals, regardless of their background.

“The minimum that we are asking for is high school graduates,” Gefen says. “They don't need to have a college degree; they just need to have aptitude. And, of course, they need to be hungry to make this change.”

2 Houston universities declared among world’s best in 2026 rankings

Declaring the Best

Two Houston universities are in a class of their own, earning top spots on a new global ranking of the world's best universities.

Rice University and University of Houston are among the top 1,200 schools included in the QS World University Rankings 2026. Ten more schools across Texas make the list.

QS (Quacquarelli Symonds), a London-based provider of higher education data and analytics, compiles the prestigious list each year; the 2026 edition includes more than 1,500 universities from around the world. Factors used to rank the schools include academic reputation; employer reputation; faculty-student ratio; faculty research; and international research, students, and faculty.

In Texas, University of Texas at Austin lands at No. 1 in the state, No. 20 in the U.S., and No. 68 globally.

Houston's Rice University is close behind as Texas' No. 2 school. It ranks 29th in the U.S. and No. 119 in the world. Unlike UT, which fell two spots globally this year (from No. 66 to 68), Rice climbed up the charts, moving from 141st last year to No. 119.

University of Houston impresses as Texas' 4th highest-ranked school. It lands at No. 80 in the U.S. and No. 556 globally, also climbing about 100 spots up the chart.

Rice and UH are on a roll in regional, national, and international rankings this year.

Rice earned top-15 national rankings by both Niche.com and Forbes last fall. Rice claimed No. 1 and UH ranked No. 8 in Texas in U.S. News & World Report's 2025 rankings. Rice also topped WalletHub's 2025 list of the best colleges and universities in Texas for 2025.

More recently, in April, both UH and Rice made U.S. News' 2025 list of top grad schools.

In all, 192 U.S. universities made the 2026 QS World University Rankings — the most of any country. Topping the global list is the Massachusetts Institute of Technology (MIT).

“The results show that while U.S. higher education remains the global leader, its dominance is increasingly challenged by fast-rising emerging systems,” says the QS World University Rankings report. “A decade ago, 32 American universities [were] featured in the world’s top 100; today, that number has dropped to 26, and only 11 of these institutions have improved their position this year."

The 12 Texas universities that appear in the QS World University Rankings 2026 list are:

  • University of Texas at Austin, No. 20 in the U.S. and No. 68 in the world (down from No. 66 last year).
  • Rice University, No. 29 in the U.S. and No. 119 in the world (up from No. 141 last year).
  • Texas A&M University, No. 32 in the U.S. and No. 144 in the world (up from No. 154 last year).
  • University of Houston, No. 80 in the U.S. and No. 556 in the world (up from 651-660 last year).
  • University of Texas at Dallas, No. 85 in the U.S. and No. 597 in the world (down from 596 last year).
  • Texas Tech University, No. 104 in the U.S. and No. 731-740 in the world (unchanged from last year).
  • University of North Texas, No. 123 in the U.S. and No. 901-950 in the world (up from 1,001-1,200 last year)
  • Baylor University, tied for No. 136 in the U.S. and at No. 1,001-1,200 in the world (unchanged from last year).
  • Southern Methodist University, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas Arlington, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at San Antonio, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at El Paso, No. 172 in the U.S. and at 1,201-1,400 in the world (down from 1,001-1,200 last year).

Houston students develop new device to prepare astronauts for outer space

space race

Rice University students from the George R. Brown School of Engineering and Computing designed a space exercise harness that is comfortable, responsive, and adaptable and has the potential to assist with complex and demanding spacewalks.

A group of students—Emily Yao, Nikhil Ashri, Jose Noriega, Ben Bridges and graduate student Jack Kalicak—mentored by assistant professor of mechanical engineering Vanessa Sanchez, modernized harnesses that astronauts use to perform rigorous exercises. The harnesses are particularly important in preparing astronauts for a reduced-gravity space environment, where human muscles and bones atrophy faster than they do on Earth. However, traditional versions of the harnesses had many limitations that included chafing and bruising.

The new harnesses include sensors for astronauts to customize their workouts by using real-time data and feedback. An additional two sensors measure astronauts’ comfort and exercise performance based on temperature and humidity changes during exercise and load distribution at common pressure points.

“Our student-led team addressed this issue by adding pneumatic padding that offers a customized fit, distributes pressure over a large surface area to reduce discomfort or injuries and also seamlessly adapts to load shifts — all of which together improved astronauts’ performance,” Sanchez said in a news release. “It was very fulfilling to watch these young engineers work together to find innovative and tangible solutions to real-world problems … This innovative adjustable exercise harness transforms how astronauts exercise in space and will significantly improve their health and safety during spaceflights.”

The project was developed in response to a challenge posted by the HumanWorks Lab and Life Science Labs at NASA and NASA Johnson Space Center for the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge, where teams worked to solve problems for industry leaders.

Rice’s adaptive harness won the Best Challenge Response Award. It was funded by the National Science Foundation and Rice’s Office of Undergraduate Research and Inquiry.

“This challenge gave us the freedom to innovate and explore possibilities beyond the current harness technology,” Yao added in the release. “I’m especially proud of how our team worked together to build a working prototype that not only has real-world impact but also provides a foundation that NASA and space companies can build and iterate upon.”
