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.

New report shows surge in startup activity in Houston and across Texas

by the numbers

Houston and the rest of Texas are experiencing a boom in the creation of startups.

One barometer of growth in startup activity: The Houston metro area saw a 92 percent rise from 2024 to 2025 in the number of account applications submitted to Bluevine, a banking platform for small businesses.

New data from Bluevine also shows healthy year-over-year growth in account applications submitted by entrepreneurs in Texas’ three other major metros:

  • 242 percent growth in the San Antonio area
  • 153 percent growth in the Austin area
  • 28 percent growth in Dallas-Fort Worth

Further evidence of Texas’ uptick in business creation comes from a new state-by-state analysis of U.S. Census Bureau data by digital mailbox provider iPostal1.

From 2019 to 2024, the number of new business applications jumped 60 percent in Texas, according to the iPostal1 analysis. Wyoming tops the list, with a five-year growth rate of 216 percent.

“The U.S. has no shortage of ambition, but opportunity isn’t spread evenly,” says Jeff Milgram, founder and CEO of iPostal1. “In states like New York, Florida, and Texas, entrepreneurship is booming — people are starting businesses, taking risks, and finding opportunity.”

“Other states are still catching up,” Milgram adds. “Sometimes it’s access to funding, sometimes local policy, or just the confidence that new ventures will be supported.”

Women own many of the new businesses sprouting in Texas, according to a new analysis of 2024-25 data from the U.S. Small Business Administration. The analysis, done by SimpleTiger, a marketing agency for software-as-a-service (SaaS), shows Texas ranks eighth for the highest concentration of women entrepreneurs (109 per 1,000 female residents) among all states. That rate is three percent higher than the national average.

“Women entrepreneurs are no longer a side story in small business growth; they’re a leading indicator of where local economies are expanding next,” SimplyTiger says. “When women-owned business density is high, it usually signals stronger access to customers, networks, and startup pathways that make it easier to launch and keep going.”

In a December news release, Gov. Greg Abbott highlights Texas’ nation-leading job gains over the past 12 months, driven by employers small and large.

“From innovative startups to Fortune 500 corporations, job-creating businesses invest with confidence in Texas,” Abbott says. “With our strong and growing workforce, we will continue to expand career and technical training programs for better jobs and bigger paycheck opportunities for more Texans.”

Houston poised to add 30,900 new jobs in 2026, forecast says

jobs forecast

Buoyed by the growing health care sector, the Houston metro area will add 30,900 jobs in 2026, according to a new forecast from the Greater Houston Partnership.

The report predicts the Houston area’s health care sector will tack on 14,000 jobs next year, which would make it the No. 1 industry for local job growth. The 14,000 health care jobs would represent 45 percent of the projected 30,900 new jobs. In the job-creation column, the health care industry is followed by:

  • Construction: addition of 6,100 jobs in 2026
  • Public education: Addition of 5,800 jobs
  • Public administration: Addition of 5,000 jobs

At the opposite end of the regional workforce, the administrative support services sector is expected to lose 7,500 jobs in 2026, preceded by:

  • Manufacturing: Loss of 3,400 jobs
  • Oil-and-gas extraction: Loss of 3,200 jobs
  • Retail: Loss of 1,800 jobs

“While current employment growth has moderated, the outlook remains robust and Houston’s broader economic foundation remains strong,” GHP president and CEO Steve Kean said in the report.

“Global companies are choosing to invest in Houston — Eli Lilly, Foxconn, Inventec, and others — because they believe in our workforce and our long-term trajectory,” Kean added. “These commitments reinforce that Houston is a place where companies can scale and where our economy continues to demonstrate its resilience as a major engine for growth and opportunity. These commitments and current prospects we are working on give us confidence in the future growth of our economy.”

The Greater Houston Partnership says that while the 30,900-job forecast falls short of the region’s recent average of roughly 50,000 new jobs per year, it’s “broadly in line with the muted national outlook” for employment gains anticipated in 2026.

“Even so, Houston’s young, skilled workforce and strong pipeline of major new projects should help offset energy sector pressures and keep regional growth on pace with the nation,” the report adds.

The report says that even though the health care sector faces rising insurance costs, which might cause some people to delay or skip medical appointments, and federal changes in Medicare and Medicaid, strong demographic trends in the region will ensure health care remains “a key pillar of Houston’s economy.”

As for the local oil-and-gas extraction industry, the report says fluctuations and uncertainty in the global oil-and-gas market will weigh on the Houston sector in 2026. Furthermore, oil-and-gas layoffs partly “reflect a longer-term trend as companies in the sector move toward greater efficiency using fewer workers to produce similar volumes,” according to the report.

Construction underway on first-of-its-kind 3D-printed community in Houston

Building a Sustainable Future

Houston is putting itself front-and-center to help make sustainable, affordable housing a reality for 80 homeowners in an innovative scalable housing community. Developer Cole Klein Builders has partnered with HiveASMBLD to pioneer what’s touted as the world’s first large-scale, one-of-a-kind, affordable housing development using 3D printing technology — merging robotics, design, and sustainability.

Located across from Sterling Aviation High School, near Hobby Airport, Zuri Gardens will offer 80 two-bedroom, two-bathroom homes of approximately 1,360 square feet, situated in a park-like setting that includes walking trails and a community green space.

Homes in Zuri Gardens will hit the market in early summer of 2026. Final pricing has yet to be determined, but Cole Klein Builders expects it to be in the mid-to-high 200s.

Interestingly, none of the homes will offer garages or driveways, which the developer says will provide a cost savings of $25,000-$40,000 per home. Instead of parking for individual units, 140 parking spaces will be provided.

Each two-story home is comprised of a ground floor printed by HiveASMBLD, using a proprietary low-carbon cement alternative by Eco Material Technologies that promises to enhance strength and reduce CO2 emissions. The hybrid homes will have a second floor built using engineered wood building products by LP Building Solutions. Overall, the homes are designed to be flood, fire, and possibly even tornado-proof.

The "Zuri" in Zuri Gardens is the Swahili word for “beautiful,” a choice that is fitting considering that the parks department will be introducing a five acre park to the project — with 3D-printed pavilions and benches — plus, a three-acre farm is located right across the street. The Garver Heights area is classified as a food desert, which means that access to fresh food is limited. Residents will have access to the farm’s fresh produce, plus opportunities to participate in gardening and nutrition workshops.

Cole Klein Builders created Zuri Gardens in partnership with the Houston Housing Community Development Department, who provided infrastructure reimbursements for the roads, sewer lines, and water lines. In return, CKB agreed to push the purchase prices for the homes as low as possible.

Zuri Gardens also received $1.8 million dollars from the Uptown Tourism Bond, 34 percent of which must be used with minority-owned small businesses. Qualified buyers must fit a certain area of median income according to HUD guidelines, and homes must be owner-occupied at all times. Zuri Gardens already has an 800-person waitlist.

“They’re trying to bridge that gap to make sure there is a community for the homebuyers who need it — educators, law enforcement, civil workers, etc.,” Cole Klein Builders’ co-principal Vanessa Cole says. “You have to go through a certification process with the housing department to make sure that your income is in alignment for this community. It has been great, and everyone has been really receptive.”

Cole has also brought insurance underwriters to visit the site and to help drive premiums below regular rates for Houston homeowners, as claim risks for one of the 3D homes are extremely low.

Tim Lankau, principal at HiveASMBLD, notes that the 3D hybrid design allows for a more traditional appearance, while having the benefits of a concrete structure: “That’s where the floodwaters would go, that’s where you can hide when there’s a tornado, and that’s where termites would eat. So you get the advantages of it while having a traditionally-framed second floor.”

It’s important to note that Zuri Gardens is not located in a flood prone area, nor did it flood during Hurricane Harvey — being flood-proof is merely a perk of a cement house. The concrete that Eco Material Technologies developed is impervious. The walls are printed into hollow forms, which house rebar, plumbing, and accessible conduits for things like electrical lines and smart house features. Those walls are then filled with a foamcrete product that expands to form a “monolithic concrete wall.”

David McNitt, of Eco Material Technologies, explains that his proprietary concrete is made of PCV, and contains zero Portland cement. Instead, McNitt’s cement is made from coal ash and is 99 percent green (there are a few chemicals added to the ash). Regardless, it’s made from 100 percent waste products.

“This is a product that has really been landfilled before,” says McNitt. “It’s coal ash, and it’ll set within 8-10 minutes. It’s all monolithic, and one continuous pour — it’s literally all one piece.”

Eco Material Technologies’ concrete product is impressively durable. A traditional cinderblock wall will crush at around 800 psi, while this material crushes at about 8,000 psi.

“It’s ten times stronger than a cinderblock wall that can withstand hurricanes,” claims McNitt. “I don’t think you’d even notice a hurricane. It’ll be really quiet inside, too — so you won’t get interrupted during your hurricane party. It’s way over-engineered, it really is.”

The second story is built using weatherproof and eco-friendly products by LP Building Solutions. Their treated, engineered wood products come with a 50 year warranty, and their radiant barrier roof decking product blocks 97% of UV rays, and keeps attic temperatures 30° cooler than traditional building materials. These materials, combined with the concrete first floor, will keep heating and cooling costs low — something the folks at HiveASMBLD refer to as “thermal mass performance.”
