  • Imagine our world expanding to a base on the moon.

  • Or an internet that comes from space.

  • It all might come Sooner Than You Think.

  • The biggest thing keeping humans from invading space is the cost of rockets.

  • Historically, getting to orbit has been pricey.

  • Somewhere between 100 million and 300 million dollars a pop.

  • And that’s kept the pace of launches stuck at only around 100 per year.

  • But if you look not so far into the future, there are signs that number will go up. Way up.

  • SpaceX proved that private companies can get to space on the cheap. And also come back home.

  • Theyve brought the cost of launch down from hundreds of millions to tens of millions.

  • In the process, theyve ignited a 21st century rocket revolution.

  • And now about ten startups are chasing them to space.

  • The leader is Rocket Lab, a company that launched for the first time this May from the coast of New Zealand

  • with a rocket forged from carbon fiber and powered by 3D-printed engines.

  • They hope to fill their small rockets with tiny satellites

  • and charge customers around $5 million for on demand access to space.

  • They plan to start launching rockets once a week and then every day.

  • But there’s just one problem with all this: economics.

  • Someone’s going to have to buy rides on all those rockets.

  • That demand for space rides will come in the form of nanosatellites, the tiny offspring of traditional satellites.

  • Companies like Google, SpaceX, Samsung and others

  • have big plans to send thousands of these cubes into space to beam internet back to the entire planet.

  • These small spaceships would form massive constellations

  • that encircle the globe with at least three times more satellites

  • than humanity has launched in its entire history

  • And it will take a lot of rockets to get them there.

  • There’s also buzz of a private moon base that would cost around $5 billion.

  • That’s a hefty sum.

  • But if you happen to be the richest man in the world and own a rocket company,

  • it probably won’t bankrupt you.

  • And getting all that stuff to the moon? Then we're talking even more rockets.

  • Right now, the supply and demand of space are stuck in a bit of a stalemate,

  • a staring contest to see which will move first.

  • But the cost of launch is dropping, and fast.

  • When the demand curve and supply curve meet,

  • 100 launches a year will become 365,

  • a launch every day, and maybe more.

  • That’s when well become a truly space-faring species.

  • And it may happen sooner than you think.

Imagine our world expanding to a base on the moon.
