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

You've heard "it's not rocket science" throughout your life, but but turns out that aerospace exploration — even in 2021 — is still very hard. Photo via Pexels

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.

Building Houston

The Hollywood-to-Houston population pipeline is overflowing, a new study suggests.

Harris County ranks as the No. 1 destination for people relocating to Texas from California, according to a StorageCafé data analysis. The No. 1 place of origin? Los Angeles County, home to Hollywood.

Among California counties, Harris County attracted the most new arrivals from Los Angeles County in 2019 (3,263), followed by San Diego County (840), and Riverside County (698).

Why are Californians swapping the West Coast for the Gulf Coast? A prime reason appears to be housing costs. The analysis shows the median price difference in 2020 between a home in Los Angeles County and a home in Harris County was $482,010. And even though they're paying less for a home in Harris County, L.A. transplants are gaining a median 577 square feet in additional space.

"When housing prices in California go up, so does migration to Texas. When housing prices in California go down, migration to Texas goes down as well," William Fulton, director of Rice University's Kinder Institute for Urban Research, tells StorageCafé, a self-storage platform.

Looking at the California-to-Texas connection, Los Angeles County holds the top seven spots in the ranking of counties that send the most new residents to our state. Here are the top seven:

  1. Los Angeles County to Harris County (3,263 new residents in 2019).
  2. Los Angeles County to Dallas County (2,492 new residents in 2019).
  3. Los Angeles County to Travis County (2,060 new residents in 2019).
  4. Los Angeles County to Collin County (1,609 new residents in 2019).
  5. Los Angeles County to Tarrant County (1,374 new residents in 2019).
  6. Los Angeles County to Bexar County (1,366 new residents in 2019).
  7. Los Angeles County to Denton County (1,290 new residents in 2019).

"Elon Musk is well on his way to being the first human on Mars, but he's far from being a pioneer when it comes to moving to Texas. His recent move to the state is just one among the almost 190 daily moves from California to Texas that occurred from 2010 to 2019," StorageCafé says.

Here are the top 10 counties for new arrivals from all California counties in 2019:

  1. Harris County — 8,408.
  2. Dallas County — 7,923.
  3. Travis County — 6,725.
  4. Tarrant County — 6,623.
  5. Bexar County — 5,340.
  6. Collin County — 5,294.
  7. Denton County — 4,028.
  8. Williamson County — 2,877.
  9. El Paso County — 2,521.
  10. Bell County — 1,727.
