Getting Psyched Up for an Asteroid Mission

Damond Benningfield, Science Writer by Damond Benningfield 4 October 20234 October 2023

The first mission to a metallic asteroid, scheduled for launch on 5 October, could provide clues to the formation of Earth and the solar system’s other inner planets.

Illustration of a water-covered planet viewed from its surface: In the foreground is rippling water reflecting pink, yellow, and white light from a glowing phenomenon in the distance, in the middle of the illustration. Surrounding the bright phenomenon are bright stars and translucent clouds visible in front of a dark background.
