Hubble and Technology
Hubble and Technology

The Hubble Space Telescope is an orbiting observatory that has beamed hundreds of thousands of celestial images back to Earth during its 25 years in space. Every 95 minutes, Hubble completes an orbit around Earth, moving at the speed of about 17,000 miles per hour (27,300 km per hour) – fast enough to travel across the United States in 10 minutes. As the telescope travels, Hubble's mirror captures light and directs it into its science instruments.
