A little while ago, NASA’s Psyche space probe blasted off atop a SpaceX Falcon Heavy rocket from the Kennedy Space Center. After just over an hour, it successfully separated from the rocket’s last stage and set off on its route that will take it into deep space, towards asteroid 16 Psyche, which it will reach towards the end of July 2029 to study its structure composed mainly of iron-nickel.

Within the asteroid belt between Mars and Jupiter and right now about 3.6 billion kilometers away from Earth, asteroid 16 Psyche is one of the largest known. It’s an M-type asteroid, the type with the highest metal content. It has an irregular shape with a maximum length of almost 280 kilometers, which brings it close to the size of a dwarf planet.
