The bare metallic core of a lifeless, early planet ought to quickly get a customer. Orbiting the solar between Mars and Jupiter, the weird area rock is the goal of a NASA mission that simply entered its last design section this week.
The area company has focused the date of Jan. 31, 2026, for the arrival of a spacecraft within the neighborhood of Psyche, a 125-mile-wide (200 kilometers) object in the asteroid belt. Planetary scientists have lengthy suspected that Psyche — named after the nymph who married Cupid in Greek mythology — made up nearly totally of iron and nickel, is likely to be the uncovered core of a long-dead protoplanet from the early days of our photo voltaic system. The planet may have as soon as boasted a girth much like that of Mars earlier than historic collisions ripped its outer, rocky shell from its comparatively dinky core.
Staff on the Psyche mission hope that their probe may present extra conclusive proof for that idea and reveal new details about the swirling cloud of matter from which our historic neighborhood first fashioned. [Black Marble Images: Earth at Night]
“With the transition into this new mission phase, we are one big step closer to uncovering the secrets of Psyche, a giant mysterious metallic asteroid, and that means the world to us,” Lindy Elkins-Tanton, an Arizona State College planetary scientist and principal investigator on the Psyche mission, said in a statement.

Psyche has a mass of about 49 billion billion lbs. (22 billion billion kilograms), making it 0.03% the mass of our moon. Whereas it is the eleventh most huge known asteroid within the photo voltaic system — a couple of hundredths of the mass of monsters like Ceres and Vesta — these even-larger asteroids are made up primarily of rock and ice. Psyche is by far the most important recognized object of its nearly-pure metallic kind orbiting our solar.
The Psyche probe ought to orbit the steel object for a pair weeks, amassing knowledge about its age and the way it fashioned. Throughout this last design section, engineers will draw up last plans for and construct lots of the components that may make up the ultimate spacecraft. (They will not be assembled into one piece till the following section, in 2021.)
If every part goes in line with plan, the mission ought to launch in August 2022, swing by Mars in 2023 and strategy Psyche three years later.
