The Asteroid Whisperers
Odin was dying in the dark. The angular 265-pound spacecraft with solar panel wings, giving it the appearance of a cyberpunk angel, was launched atop a SpaceX Falcon 9 rocket on February 26, 2025. It was to swoop past 2022 OB5, a rocky asteroid island adrift in a starry sea, and take photographs of it. Odin successfully left its ride, headed into space—and vanished. The asteroid scout had barely begun its five–million–mile journey from Earth, and it was powerless to reach its destination. Flying through space is eventful. Temperature extremes in and out of sunlight range from hundreds of degrees above and below zero, which can cause spacecraft to warp. Corrosive cosmic radiation coming from the sun or from distant exploding stars can eat away at electronic circuitry. Bullet-like micrometeorites zooming past at high velocity can potentially pierce through metal like a hot knife through butter. “Any one of them can kill your spacecraft,” says Philip Metzger, a planetary physicist at the University of Central Florida.
