Falcon Heavy May Have Drastically Increased the Number of Asteroids We Can Mine

eroid mining is about more than just heading up into space and bringing back a rock full of platinum—you actually need to land something on just the right asteroid.

Falcon Heavy, the world’s most powerful rocket launched by Elon Musk-led SpaceX two weeks ago, may have changed the game, says one astronomer.

“Instead of a few hundred we may have thousands of ore bearing asteroids available,” Martin Elvis from the Harvard-Smithsonian Center for Astrophysics told an audience at the American Association for the Advancement of Science annual meeting in Austin, Texas.

Asteroids could be ripe with natural resources, including water and heavy metals like platinum, as we’ve reported. Space colonialists like Planetary Resources hope to get mining equipment onto one of those nearby ‘roids to bring the resources back down to Earth and turn into space John D. Rockefellers. But there are tons of challenges—including landing on the asteroids themselves.

Scientists calculate how accessible asteroids are based on a measure for each asteroid called delta-v, change in velocity. This is a shorthand for how much thrust it would take to switch orbits between low-Earth orbit and orbit around asteroid, Elvis once wrote in a paper. It’s measured in units of kilometers per second. Asteroids can have delta-vs from 4 to almost 30 km/s.
