Regarding the statements made at the end of the article (specifically, the ones to which I have added bold emphasis): unless and until we start "tak[ing] advantage of the value" (by "bring[ing] any of this material back and using it for industry," for example), humanity is never going to establish any kind of enduring presence in space.
All the talk about permanent bases on the Moon or manned missions to Mars is just talk. Even if we do those things, it won't last unless and until we start getting more economic value out of it than we put into it. (That's why the Apollo program didn't result in anything lasting - once the political purpose of beating the commies to the Moon had been served, there was no longer any incentive to continue doing it.)
Mining the asteroids is certainly not yet within our capabilities. But sooner or later, it (and other such activities) is going to have to be done. Otherwise, the idea of humanity traveling beyond the confines of Earth on anything other than temporary excursions will never be more than a pleasant pipe-dream and the subject of science fiction stories ...
Hubble telescope gives closer look at rare asteroid worth $10,000,000,000,000,000,000

There's an extremely rare metallic asteroid lurking between Mars and Jupiter, and it's worth more than the entire global economy. Now, the Hubble Space Telescope has given us a closer look at the object, which is worth an estimated $10,000 quadrillion.
A new study this week in The Planetary Science Journal delves deeper than ever before into the mysteries of the asteroid 16 Psyche, one of the most massive objects in the solar system's main asteroid belt orbiting between Mars and Jupiter, about 230 million miles from Earth. It measures about 140 miles in diameter - roughly the size of Massachusetts.
Most asteroids are made of rocks or ice. But 16 Psyche is dense and mostly made of metal, possibly the leftover core of a planet that never succeeded in forming - a so-called "protoplanet," which had its core exposed following hit-and-run collisions that removed the body of its mantle.
The study marks the first ultraviolet (UV) observations of the celestial object. New data reveals the asteroid may be made entirely of iron and nickel - found in the dense cores of planets.

Metal asteroids are rare, so Psyche provides researchers with an exciting opportunity to study the inside of a planet. In 2022, NASA plans to launch the unmanned spacecraft Psyche on a SpaceX Falcon Heavy rocket to study the asteroid in an attempt to understand its history and that of similar objects - the first time a mission will visit a body made entirely of metal.
The orbiter is set to arrive at the asteroid in January 2026 to study it for nearly two years. The mission's leader at Arizona State University estimates that the iron alone on today's market would be worth $10,000 quadrillion - that's a one followed by 19 zeroes.
[...]
Researchers told CBS News in 2017, when the mission was confirmed, that they don't plan to take advantage of the value of the asteroid's composition.
"We're going to learn about planetary formation, but we are not going to be trying to bring any of this material back and using it for industry," Carol Polanskey, project scientist for the Psyche mission, said at the time.
