Mark Rober has made a career out of engineering, entertainment, and education. After completing degrees in mechanical engineering from Brigham Young University and the University of Southern California, Rober joined NASA’s Jet Propulsion Laboratory in 2004. In his nine years as a NASA engineer, seven of which were on the Mars rover Curiosity team, Rober worked on the Descent Stage (the jet pack that lowered the rover to the surface) and was responsible for some hardware on the rover top deck used for collecting dirt samples. After NASA, he moved to Silicon Valley and worked for 5 years doing Product Design in Apple’s Special Projects group. In 2011, Rober’s iPad-based Halloween costume inadvertently helped launch his YouTube channel, which now boasts over 22 million subscribers, 3B views and averages over 30M views per video. According to Mark, his passion is “getting people pumped about science and education” and he does that through making compelling engineering builds such as the World’s Largest Super Soaker or Nerf Gun. His most popular creation with over 84M views, is when he engineered a bait package that could shoot glitter fart spray in response to falling victim to porch pirates. Rober has guest hosted and is a regular guest on "Jimmy Kimmel Live!" and is working together with Jimmy on a science based prank show that will premiere on the Discovery channel in 2022.
