Once used to sneak up on enemy warships undetected, submarines of today help to open up an entire untouched underwater world deep below the surface. From WWII's oxygen-hungry diesel subs to the modern marvels like USS Nautilus, propelled by silent nuclear power, witness the evolution of underwater travel. Thanks to evolutions in submersible designs and technology, the submarines of today are much more than wicked war machines. Modern day subs are capable of carrying entire cities on their backs, breaking mega blocks of ice and touching down at the deepest, darkest points of our oceans. As drones redefine underwater exploration, meet the autonomous Orca and decode its communication systems. Explore how submarines silently patrol with unmatched technology, revolutionizing the aquatic domain.

Human kind has always looked to the heavens to dream of the universe beyond our world, today that dream is within reach. Scientists may have conquered our atmosphere decades ago, but modern desires to make space travel accessible for the masses means rethinking the way we design our rockets. The modern-day space race is all about resources and reusability, but how exactly do companies like SpaceX, Virgin Galactic and Blue Origin hope to perfect this process? With longer manned missions on the docket for the world's space exploration programs, it's important that we get thinking about fuels of the future. Could the rockets of tomorrow carry mini nuclear rectors on board as well as people? Or will we need to farm precious elements from space to ensure that intergalactic tourists rely on a return flight home?
