  • Earlier this month, China made history by becoming the first country to land softly

  • on the far side of the moon.

  • What makes this mission especially difficult is that, unlike those on the near side, this

  • one never has a direct view of Earth.

  • To communicate, the rover has to use a special relay satellite, positioned between them.

  • But for all that extra work, the Chang'e 4 gives China international recognition.

  • It's not just another landing among many.

  • And this is just the beginning.

  • In 2017, France spent two billion dollars on space, Russia, three billion, the European

  • Space Agency, six, and China, eleven.

  • And sure, that's still far less than NASA, at almost 20 billion,

  • But the U.S. also spends three times more on healthcare for the same life expectancy,

  • so money isn't everything.

  • China is also opening up to private space companies, which quietly compete with those

  • in America, like SpaceX and Blue Origin.

  • Spacety, for example, specializes in micro-satellites weighing as little as 3 pounds each, a previously

  • unfilled, but profitable, niche.

  • This rapid increase of Chinese investment in space will generate thousands of jobs and

  • countless scientific discoveries.

  • But it isn't just about space,

  • It's also a calculated, military strategy with global consequences.

  • 30,000 feet in the air, moving 800 kilometers per hour, you can watch this very video thanks

  • to the $260 billion a year industry that issatellites.

  • With them, we can predict the weather, snoop on our neighbors, and, of course, watch TV.

  • For free, by the way, if you live in Dish, Texas, which legally changed its name in 2005

  • in exchange for 200 free channels.

  • Could be worse.

  • But perhaps most important are the 31 satellites which form the Global Positioning System.

  • Cargo ships, carrying 90% of the world's goods, use it to navigate.

  • Precision farming makes plowing, planting, and fertilizing vastly more efficient.

  • Pilots use it to fly, Surveyors to measure boundaries, and you and I, to get delivered

  • the finest Italian cuisine money can buy.

  • But determining where you are is, arguably, not even its most important function.

  • It's also the world's clock - keeping the time for everything from the New York

  • Stock Exchange, to credit card transactions, and ATMs, with an accuracy of one billionth

  • of a second.

  • Its no exaggeration to call GPS one of the foundations of the global economy.

  • So, what does it cost?

  • Absolutely nothing.

  • If you're an American taxpayer, it's ”included”.

  • But for everyone else, this $1.4 billion a year service is provided 100% free.

  • There's just one catch: GPS is owned and operated by the United States Air Force.

  • Like the internet, it was originally developed by and only for, the military.

  • But in 1983, Korean Air flight 007 from Anchorage to Seoul made a very costly navigation mistake.

  • Instead of flying around restricted Soviet airspace, it unintentionally flew over the

  • Kamchatka peninsula, and on the same day as a missile test at the same location.

  • After tracking the aircraft for over an hour, it was shot down, killing all 269 people on

  • board.

  • To prevent this from happening again, President Reagan made GPS freely available for civilian

  • use.

  • And in 2000, President Clinton ended Selective Availability, granting everyone, not just

  • the military, access the same level of accuracy.

  • Officially, quoteIt is not the intent of the U.S. to ever use Selective Availability

  • again.”,

  • Which, notably, is not the same asWe can't deny access ever again”.

  • During the war between India and Pakistan in 1999, the U.S. refused to give India access

  • to GPS data.

  • Much more recently, in 2012, a disabled GPS satellite was blamed for a failed Russia-India

  • missile test.

  • That uncertainty is enough to make foreign countries nervous.

  • And now consider that this hugely important, economy-running technology can be interrupted

  • with a $10 spoofing device.

  • Because GPS signals are weak by the time they reach the ground, it's remarkably easy to

  • emit a stronger, competing signal.

  • This device, for example, can trick nearby cars into going the wrong way or crashing

  • into other vehicles.

  • In 2008, Newark airport became the first in America to use the FAA's NextGen GPS system

  • for tracking planes, which frequently, inexplicably stopped working.

  • A three-year investigation found a trucker on the nearby New Jersey Turnpike using a

  • GPS jammer to stop his employer from tracking him.

  • Like the drone which shut down the UK's second busiest airport in December, GPS jamming

  • is so dangerous because it costs so little to do so much damage.

  • One, single drone, 100,000 passengers and 760 flights affected.

  • For all these reasons, several countries are launching their own alternatives to GPS.

  • Russia has GLONASS, The EU has Galileo, and China, Beidou.

  • Technically, none of these systems are directly competing.

  • 60% of receivers use at least two of them simultaneously.

  • But it's also in each country's interest to control as much navigation as possible.

  • It's also part of China's goal to secure its claim to the South China Sea.

  • The problem is, just about everyone is watching, including the U.S., which routinely sends

  • ships to patrol the region.

  • In October, one of them nearly collided with a Chinese destroyer.

  • So, the challenge for China is asserting its claim without risking conflict between 2 nuclear

  • powers.

  • Its solution are nicknamed thelittle blue men” - local fishermen sponsored by the

  • government to work in the area and report foreign activity to the military.

  • This way, it asserts its claim, benefits economically, and does so in a less-threatening way.

  • But these fishermen have become a target for nearby countries, like Indonesia.

  • Which is where Beidou comes in.

  • Unlike GPS, China's version allows receivers to send short messages and request military

  • assistance.

  • It gives fishermen the full power of the People's Liberation Army without carrying a single

  • weapon.

  • This is the tension created by China's ambitions in space.

  • Whether it's purely motivated by research and science or not, doesn't really matter.

  • Either way, it's going to be interpreted aggressively by established powers like the

  • United States.

  • Space technology is, at least for now, closely tied to the military.

  • It's just one more way the world will have to adapt to, or risk escalation with, the

  • meteoric rise of China.

  • Investing in space is about exploring the unknown for the sake of discovering new things.

  • And Skillshare offers that same kind of feeling when you learn something new,

  • Like solving a Rubik's cube, taught by the master of learning new things, YouTuber Mike

  • Boyd,

  • or let the amazing Thomas Frank teach you how to be more productive.

  • Whatever you want to learn - investing, design, writing, or animation, Skillshare has high-quality

  • video courses that will help you.

  • I'll take a guess and say you enjoy watching YouTube videos, so why not learn new skills

  • from those very same YouTubers?

  • If you're one of the first 500 people to sign up with the link in the description,

  • you'll get two free months of all the lessons you could possibly want.
