I think it's really a sign of great American strength that we do invest the money we do in technology, in these hard projects, in NASA.

One of the things that happens in space is that there is a fluid shift. You get a lot of extra pressure, and it fills your sinuses, and the horseradish is a miracle worker for cleaning that out.
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.
John M. Grunsfeld -
The truth is, every single rocket launch off of planet Earth is risky.

I'm an incurable romantic. But I'm not an adrenaline junkie.

The only reason Hubble works is because we have a space shuttle.

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.

As a young boy growing up on the South Side of Chicago, I was inspired by the nascent space age.

When I first went to Hubble, as an astronomer and as a scientist, it was a dream come true. And as an astronaut, the Hubble missions are premiere missions because Hubble is so important to science, so important to humanity, that it's just a very special event. But as an astronomer, it was sort of the holy grail of missions.

We're being very careful that we don't send a spacecraft to Mars with the intention of detecting Martian life - and find out that we detected the Earth life that we took with us.

Here we were, the only seven humans in space, repairing a telescope whose only purpose is to enrich the minds of people on planet Earth and increase our understanding of the workings of the universe. I can think of no better peaceful use of space for all humankind.

At the age of six, I declared that I wanted to be an astronaut. My mother thought that was just fine, as it would encourage me to learn science, and besides, there really was no chance I would ever actually become an astronaut.

After my spacewalks, I am quite exhilarated but also tired, similar to a workout on Planet Earth.
John M. Grunsfeld -
What we do at NASA is inspiring. It's reaching, it's visionary, and it inspires people on Earth to try hard things.
John M. Grunsfeld -
Are we alone? Many, many people on planet Earth want to know. We are on the cusp of being able to answer that question... because of the investments we're making in space technology.

Being an astronaut, there are not a lot of things that have really shocked me in my life.

Asteroid detection, tracking, and defense of our planet is something that NASA, its interagency partners, and the global community take very seriously.
John M. Grunsfeld -
Sometimes astronauts feel a little ill or get minor scrapes. I trained as a crew medical officer to do basic treatment.
