On this day in space! Oct. 29, 1991: NASA's Galileo spacecraft flies by asteroid Gaspra and snaps amazing photos while flying at 18,000 mph

A Historic Flyby on the Way to Jupiter

On October 29, 1991, NASA's Galileo spacecraft performed a historic flyby of the asteroid Gaspra while en route to its primary target, Jupiter. This encounter marked a major milestone in planetary exploration, allowing scientists to examine an asteroid up close for the very first time in history.

Capturing Images at 18,000 Miles Per Hour

Travelling at a thrilling speed of 18,000 mph, Galileo snapped high-resolution photos and gathered crucial data during its brief rendezvous with Gaspra. Despite the high velocity, the spacecraft successfully captured clear images revealing the surface details and overall shape of the distant space rock.

A Milestone for Small Body Exploration

The successful Gaspra flyby revolutionized our understanding of small solar system bodies and asteroid characteristics. The data provided invaluable insights into planet formation models and paved the way for future robotic missions targeting asteroids and comets throughout the solar system.
