In 2022, if all goes well, NASA will launch Psyche, a space probe intended to visit the asteroid of the same name (16 Psyche is its formal designation). It’s a particularly exciting mission given Psyche’s unique nature and highly unusual composition.

The asteroid belt is composed of three types of asteroid: C-type (carbonaceous, ~75 percent of all asteroids), S-type (silicate-rich, ~17 percent of asteroids) and M-type (metal-rich), which are roughly 10 percent of the total population. The numbers, in this case, don’t add up to 100 percent because we aren’t sure of the exact ratios. 16 Psyche is an M-type asteroid made of iron-nickel. What makes it unusual is that it’s believed to be the now-exposed core of a protoplanet. It’s also estimated to be worth $10,000 quadrillion dollars, if anybody has a towing hitch handy.

16 Psyche isn’t large — its radius is estimated at 112 km, and it isn’t round. Our current best estimate of its composition indicates that it’s 90 percent iron. Its parent body, assuming that it had one, is assumed to have been approximately 500km in diameter, or roughly half the size of Ceres. If Psyche is a core remnant it’s possible that others remain as well, but the asteroid isn’t part of any known family. One theory for its formation is that it was struck a number of times, but never with enough force to shatter it. The remaining fragment represents the iron core of a protoplanet, possibly covered by a thin layer of silicates or remnant components of the original mantle.

Just as the modern computer transformed our relationship with bits and information, AI will redefine and revolutionize our relationship with molecules and materials. AI is currently being used to discover new materials for clean-tech innovations, such as solar panels, batteries, and devices that can now conduct artificial photosynthesis.

Today, it takes about 15 to 20 years to create a single new material, according to industry experts. But as AI design systems skyrocket in capacity, these will vastly accelerate the materials discovery process, allowing us to address pressing issues like climate change at record rates. Companies like Kebotix are already on their way to streamlining the creation of chemistries and materials at the click of a button.

Atomically precise manufacturing will enable us to produce the previously unimaginable.

The cosmos are filled with roughly Earth-sized exoplanets. Various moons, comets, and planets have stores of water, organic molecules, and amino acids like those that make up life on Earth.

Cathal O’Donnell, a 3D bioprinting researcher at St. Vincent’s Hospital in Melbournethose odds — he argues in The Conversation that the abundance of potentially habitable worlds out there makes the discovery of extraterrestrial life “inevitable and possibly imminent.”
