Long before building viral glitter bombs or designing elaborate squirrel obstacle courses, Mark Rober spent nine years as a mechanical engineer at the National Aeronautics and Space Administration (NASA). Seven of those years were dedicated entirely to the Jet Propulsion Laboratory (JPL), where he helped design hardware for the Mars Curiosity Rover. When he walked away from aerospace in 2013, it wasn't due to a scandal or a failed launch. He left because his side project—making creative internet videos—began growing faster than his day job could satisfy his creative hunger.
Understanding why Mark Rober left NASA requires looking at how his early digital experiments took off, what his day-to-day engineering life looked like, and how he navigated the terrifying jump from traditional aerospace to full-time content creation.
Inside the Nine Years at NASA and JPL
Mark Rober earned his bachelor's degree in mechanical engineering from Brigham Young University and later his master's degree from the University of Southern California. Fresh out of school, landing a job at NASA felt like the ultimate pinnacle for a mechanical engineer.
At JPL, Rober worked on major hardware and analysis projects. Most notably, he spent seven years working on the Curiosity Rover mission, which successfully touched down on the Martian surface in August 2012. His day-to-day responsibilities involved intense mechanical design, thermal analysis, and ensuring delicate scientific instruments could survive the brutal vibrations of a rocket launch and the harsh vacuum of deep space. Additional analysis by Bloomberg explores related perspectives on this issue.
Beyond hardware engineering, Rober also contributed to internal knowledge management. He was a primary architect for "JPL Wired," an internal wiki designed to capture corporate knowledge and engineering best practices across teams. To his peers inside the space program, he was a sharp, highly competent engineer with a bright career ahead of him.
The Birth of a Viral Side Hustle
While designing parts for a nuclear-powered rover destined for Mars, Rober started tinkering with video production on the side. In October 2011, he uploaded his very first YouTube video: a creative Halloween costume that used two hidden iPads to create an optical illusion of a gaping hole straight through his torso.
The video went viral almost overnight, racking up millions of views and appearing on major morning talk shows. Seeing the immediate global reach of a simple engineering trick planted a seed. He quickly launched a company selling specialized Halloween t-shirts based on the concept, which he later sold to a UK-based firm.
Suddenly, Rober was managing a booming online business while maintaining a demanding 9-to-5 engineering job at NASA. The contrast between the two worlds was stark. At NASA, major projects took a decade to move from concept to execution. On the internet, he could build an idea in his garage on Saturday, upload it on Sunday, and see millions of people react by Monday.
Why He Left NASA in 2013
Rober didn't quit NASA to go straight to YouTube. In 2013, after nine years at the space agency, he accepted a role at Apple as a product designer in their Special Projects Group. He spent four years at Apple, working on secretive hardware initiatives and even authoring a patent involving virtual reality in self-driving cars.
The transition to Apple provided a faster corporate pace than NASA, but the underlying pull of digital storytelling kept growing. By 2019, Rober finally made the complete leap to running his channel full-time, six years after leaving NASA and shortly after wrapping up his stint at Apple.
The primary catalyst for leaving traditional engineering was creative autonomy. In aerospace and corporate tech, you work on massive teams where your specific contribution is a tiny fraction of a multi-billion-dollar machine. You are bound by strict non-disclosure agreements and bureaucratic review boards. On YouTube, Rober had total control over the narrative, the design, and the educational payoff. He realized he could use his elite engineering background to teach physics and mechanical principles to millions of kids around the world, turning complex science into pure entertainment.
How His NASA Background Shaped His Channel
Leaving NASA didn't mean abandoning his engineering roots. In fact, every viral video Rober produces relies directly on the systematic problem-solving methods he learned at JPL.
- Rigorous Prototyping: Whether he's building a squirrel ninja warrior course or a glitter bomb trap for porch pirates, he uses iterative engineering testing, CAD design, and scientific measurements.
- Scale and Scope: Working on a Mars rover trains your brain to think about worst-case scenarios, structural tolerances, and environmental variables—skills that come in handy when building the world's largest Nerf gun or an elephant toothpaste fountain.
- The Heart of an Educator: NASA instilled in him a deep appreciation for public science communication. That passion eventually expanded beyond YouTube into founding CrunchLabs, an educational technology company that sends monthly build boxes to kids to foster hands-on engineering skills.
Frequently Asked Questions
Did Mark Rober get fired from NASA?
No. Mark Rober left NASA voluntarily in 2013 after working there for nine years to pursue other engineering and creative opportunities, eventually joining Apple before moving to full-time content creation.
What did Mark Rober actually do on the Mars Curiosity Rover?
He worked as a mechanical engineer at the Jet Propulsion Laboratory, spending seven of his nine NASA years designing hardware, analyzing thermal properties, and solving mechanical challenges for the Curiosity Rover mission.
Does Mark Rober still work as an engineer?
Yes, though not in the traditional corporate sense. He treats his YouTube channel and his educational company, CrunchLabs, as large-scale engineering workshops where he designs complex, custom mechanical builds for millions of viewers.
Why did Mark Rober transition from Apple to YouTube?
While his four years at Apple involved cutting-edge product design, his side channel had grown into a massive platform with global reach. He chose full-time content creation because it offered absolute creative freedom and an unmatched ability to inspire the next generation of scientists.
