Quotes from John M. Grunsfeld

There is no stronger case for the motivational power of real science than the discoveries that come from the Hubble Space Telescope as it unravels the mysteries of the universe.

The James Webb Space Telescope was specifically designed to see the first stars and galaxies that were formed in the universe. So we're gonna see the snapshot of when stars started. When galaxies started. The very first moments of the universe. And my bet? There's gonna be some big surprises.

Science fiction has been an inspiration to generations of scientists and engineers, and the film series 'Star Wars' is no exception.

Our journey in going beyond our home planet is a human endeavor, and in the greatest tradition of exploration, past, present, and future spacefarers will continue to be enduring catalysts for inspiration in our quest to unravel the mysteries of the universe.

I look forward to working with the NASA team to help enable new discoveries in our quest to understand our home planet and unravel the mysteries of the universe.

The strangest thing I've found is that when I got to space, I felt more comfortable in space that I've ever been on Earth before. I just felt this is my home.

Hubble has really opened our eyes to what the universe is made of, its structure, and has helped us learn how little we know about the universe.

Because of Hubble and other telescopes, we've now discovered that there are probably planets around every star, or virtually every star. There are solar systems around most stars. And the fact that we're here on a planet, Earth, means that it's likely there's lots of other Earths out there.

What we do at NASA is inspiring. It's reaching, it's visionary, and it inspires people on Earth to try hard things.

Once in a while, the universe lets you be free alone and in peace.

We need to move off the planet. And Mars is the next best place.
