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.
Quote by -John M. Grunsfeld
I'm absolutely compelled for NASA to send international astronauts to Mars to find out if Mars ever harbored life.
Quote by -John M. Grunsfeld
Sometimes astronauts feel a little ill or get minor scrapes. I trained as a crew medical officer to do basic treatment.
Quote by -John M. Grunsfeld
The things I like to do involve a lot of mental focus, a combination of physical and mental challenge. That is what mountain climbing is.
Quote by -John M. Grunsfeld
The Martian atmosphere is very thin. It's like our atmosphere at 100,000 feet.
Quote by -John M. Grunsfeld
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.
Quote by -John M. Grunsfeld
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.
Quote by -John M. Grunsfeld
Being an astronaut, there are not a lot of things that have really shocked me in my life.
Quote by -John M. Grunsfeld
The first thing to know about space food - it is the ambiance; it is the environment. It is not the food.
Quote by -John M. Grunsfeld
I don't particularly want to jump out of an airplane with a parachute if I don't have to. I don't want to go bungee jumping. I like adventure with a real purpose that I can buy into.
Quote by -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.
Quote by -John M. Grunsfeld
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.
Quote by -John M. Grunsfeld
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.
Quote by -John M. Grunsfeld
Hubble uniquely has been able to look in the atmosphere of a planet orbiting a nearby star and figure out what's in that atmosphere.
Quote by -John M. Grunsfeld
The surface of Mars is bathed in ultraviolet light, bathed in radiation. Mars's magnetic field is essentially gone, so the surface of Mars is essentially sterilized.
Quote by -John M. Grunsfeld
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.
Quote by -John M. Grunsfeld
Small bodies in our solar system, like comets and asteroids, help us understand how the solar system formed and provide opportunities to advance exploration.
Quote by -John M. Grunsfeld
I have had the privilege to be a member of many high-performance teams at NASA, both on and off the planet.
Quote by -John M. Grunsfeld
Absolutely the most fun thing to do in space and rewarding thing, in many ways, is to look back at planet Earth.
Quote by -John M. Grunsfeld
To help enable the kind of science Hubble is performing makes my life worthwhile.
Quote by -John M. Grunsfeld
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.
Quote by -John M. Grunsfeld
Our country... invests a tiny fraction of 1 percent in NASA, and this is what's so amazing to me, is with that small investment, we do so much for the country.
Quote by -John M. Grunsfeld
The most striking thing to me about human space flight and my own personal experience is that I've seen dramatic changes on Earth. We humans are rapidly changing the planet. I've watched Amazonia as the rainforest has been cut down. That's something I've seen out the window. I'm very worried about that.
Quote by -John M. Grunsfeld
We don't know how many planets we're going to have to examine before we find life, and not finding it on 10 or 100 doesn't mean it's not there. This may be very tricky.
Quote by -John M. Grunsfeld
As a young boy growing up on the South Side of Chicago, I was inspired by the nascent space age.
Quote by -John M. Grunsfeld
Once we get beyond Mars, which formed from the same stuff as Earth, the likelihood that life is similar to what we find on this planet is very low.
Quote by -John M. Grunsfeld
It's pretty amazing to me that we have had a space shuttle program that's lasted for 30 years - for one space shuttle. That's quite an achievement.
Quote by -John M. Grunsfeld
InSight will get to the 'core' of the nature of the interior and structure of Mars, well below the observations we've been able to make from orbit or the surface.
Quote by -John M. Grunsfeld
Regardless of what dreams you have, work very hard, play very hard, and have fun.
Quote by -John M. Grunsfeld
I see no difference between scientific exploration and human exploration.
Quote by -John M. Grunsfeld
Science fiction has been an inspiration to generations of scientists and engineers, and the film series 'Star Wars' is no exception.
Quote by -John M. Grunsfeld
Growing up in Highland Park, in high school, I had some very influential teachers: I had a math teacher who taught calculus that helped me learn to be in love with mathematics; I had a chemistry teacher who inspired us to work what was in the class and to go beyond.
