Summary

The European Space Agency’s Hera probe captured images of Mars’s smaller moon, Deimos, during a high-speed flyby.

The 8-mile-wide, dust-covered moon, tidally locked with Mars, remains poorly understood. Scientists believe it could be debris from an impact or a captured asteroid.

The flyby, part of Hera’s journey to study asteroids, used a gravity assist to propel the probe toward Dimorphos, a moonlet of Didymos.

Hera will analyze Dimorphos, which NASA’s Dart probe hit in 2022, to assess asteroid deflection strategies for planetary defense.

This reminds me of the book The Little Prince. There was also a cartoon about a child who would catch these asteroids with a butterfly net of sorts, maybe based on the book, that lives in the back of my brain that pokes its head out every blue moon. Pun intended.
