Dr. John Grunsfeld: NASA Astronaut and Astronomer

  • Released Monday, September 14, 2020

As an astronaut who operated on Hubble multiple times in orbit, Dr. John Grunsfeld has a unique relationship with the telescope. He’s watched Hubble drift against the background of Earth and stars, and he’s guided new parts and instruments into the telescope and left it whole and healthy.

His quest to become an astronaut started at 6 years old. As a child, he toted a lunch box decorated with a NASA Gemini theme, celebrating an early human spaceflight program.

This video features Dr. Grunsfeld going over his unique bond with the Hubble Space Telescope.
