As NASA looks to explore deeper into our solar system, one of the key areas of interest is studying worlds that can help researchers better understand our solar system and the universe around us. One of the next destinations in this knowledge-gathering campaign is a rare world called Psyche, located in the asteroid belt.
Psyche is different from millions of other asteroids because it appears to have an exposed nickel-iron surface. Researchers at Arizona State University, Tempe, in partnership with NASA's Jet Propulsion Laboratory in Pasadena, California, believe the asteroid could actually be the leftover core of an early planet. And, since we can't directly explore any planet's core, including our own, Psyche offers a rare look into the violent history of our solar system.
"Psyche is a unique body because it is, by far, the largest metal asteroid out there; it's about the size of Massachusetts," said David Oh, the mission's lead project systems engineer at JPL. "By exploring Psyche, we'll learn about the formation of the planets, how planetary cores are formed and, just as important, we'll be exploring a new type of world. We've looked at worlds made of rock, ice and of gas, but we've never had an opportunity to look at a metal world, so this is brand new exploration in the classic style of NASA."

All very nice. (I hope it isn't magnetic...)

What's all that metal worth?

What's all that metal worth?
A lot less, the day it is mined--with one thing not factored in: That metal is already up there. Its value is in savings of lift costs from Earth.
