SPACE: NASA’s Psyche spacecraft just got an assist from Mars on the way to its asteroid namesake. “Scientists think that Psyche, the largest known metallic asteroid in our solar system, could be part of the iron-rich core of a planetesimal. That’s the solid building block of a planet formed in the early days of the solar system. As such, it could offer us insight into the core of our own planet and show us how it formed.”

And it appears to be a treasure trove of raw materials that aren’t stuck in Earth’s gravity well.
