I would like you to join me as we look up to space in a completely different way. Not just because of its beauty, or the mysteries that it holds, but because of the value that it represents for the future of humankind.
The year is 2062. One of the children of your children is about to go up on a mission to a space rock, an asteroid I know what you’re going to tell your grandkid “Darling, why did you pick such a boring dry destination in space?” “Well, think again, grandpa. Watch me go, grandma.” And there goes your grandkid on a one-month trip to an asteroid the size of this stage, one of hundreds passing close to Earth every year.
As it accelerates up to 40,000 miles an hour, the spacecraft finally catches up with the asteroid, turns a magnifying glass, focuses the energy on the surface of the rock, heating it up until gases and water come spewing out of it. Water that can be collected for up to a crew of four astronauts for drinking purposes. Also, to grow plants that they can serve as food. To extract oxygen from the water, so they can breathe inside their capsules and their spacesuits.
Water, that once heated turns into steam, that can propel that rocket to other destinations for up to four years, to other asteroids, to the Moon, and even have enough fuel and supplies left to bring the crew back to our planet, 50 years from now, to exactly the same place where we are all gathered here, today, so that that your grandkid can deliver the master talk at the TEDxMileHigh 2066 event.
And what would be the title of that talk? “How I learned to live off-the-land…in space.” So grandma, grandpa, next time you see a boring dry rock like this, think of it instead as a celestial gas station with a convenience store attached to it. Oh, thank heavens! What your grandkid has done is to extract resources to live and work in space, cutting our dependence from Earth, from where we have sent all the fuel, supplies, and equipment for the thousands of rockets since the beginning of the Space Age in the 1950s. We depend 100% from the resources of our planet to explore space, and that is obviously not an efficient or sustainable way to explore.
It won’t get us very far. It is also not an economical proposition. Tons of fuel are needed to power a spaceship to overcome gravity that wants to keep us firmly on the ground. 90% of the weight of a rocket is fuel that is needed to launch that tiny little capsule where the astronauts, and their materials, and supplies are housed. It costs more than $10,000 a pound to send anything into space. 2 million dollars alone are necessary to launch me up there, nearly my weight in gold. And let me tell you, I’m a bargain.
Because of all the extra weight of hair that I don’t have to carry around. We know from our experience here on Earth that on the long cross-country trips, we don’t take all the fuel, or all the food that we need. No! We use resources where we find them.
And if you want to know what this strategy has allowed us to do to explore our planet, let’s now go back in time, to circa 124,000 BC, to meet not your descendants in space, but your ancestors, the homo sapiens, who, after years of drought, and environmental degradation, and population growth, left their birthplace, their cradle in Africa, for other parts of the continent, to Europe, in all sorts of regions in Asia, looking for basic survival, food, and water.
And in the process, they learned how to control certain technologies, control fire, and to preserve food. Then, about the time they crossed to the Americas, about 15,000 years ago, they discovered agriculture, that allowed them to settle in first villages, then towns, and then cities. Then on the second wave of exploration, in the 15th century. Once they learned how to navigate the oceans, the search was for more exotic elements that were important to society back then: gold, silver, spices, silk.
Then in the 19th century, it was about drilling for oil all over the planet, which has become our main source of energy. And just 20 years ago, the search has been for those rare elements in the periodic table that are now part of your cell phones and the cars that you drove up here today. So resources are what drives our economy, our society, our very existence. And as you can see, this insatiable search for resources has allowed us to live off the land in ever more extreme environments, to explore every corner of our planet, and to dig as deep as possible, searching for anything that can be of use to us.
So, where to go next? It’s time to look up to space. Premature and economical, science fiction you might say. Not really. In fact, the process has already started 50 years ago, we pierced our atmosphere for the first time and left our planet. Yes, first for political reasons, the US versus the Soviet Union on their way to the Moon. Then for scientific purposes. But something happened on our way to heaven. We realized that space had value, that it could be useful to us, and without noticing it, we have become increasingly dependent on space’s first utilized resource, our ability to look at our Earth from up above.
This is giving us weather forecast, and global communications, and a GPS network that allows us to pinpoint every location on the surface of the Earth with extreme accuracy. Not only that. The view from above has given us a view of the fragility of the Earth, and also to assess the damage that we’re causing on this relentless quest for Earth resources. So space is already an integral part of our lives, our society, our economy. And we have only just begun.
