When we first sent missions to Jupiter, no one expected to find moons that would have active volcanoes. And I could go down a long list of how often I've been surprised by the richness of nature.
Quote by -Alan Stern
We really just didn't realize the diversity of planetary types in our solar system. Pluto looked like a misfit because it was the only one we saw. And just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies. They're large enough to make themselves round by self gravity, and they surely pass the test of planethood.
Quote by -Alan Stern
I tell public audiences, don't go to a podiatrist for brain surgery; don't go to an astronomer for planetary science.
Quote by -Alan Stern
No one working as an astronomer is shackled in chains. This is a tremendous profession. There are lots of neat people, and you get to do cool things. If I had to say something negative, it's that there's often a whole lot of travel that takes me away from my children. That can be a bummer a lot of times.
Quote by -Alan Stern
I like the planets because they are real places that you can go to and send machines to. Faraway astronomy - galactic astronomy and extra-galactic astronomy - is really cool stuff, but to me, it's about destinations.
Quote by -Alan Stern
We're in the space exploration business, and the outer solar system is a wild, wooly place. We haven't explored it very well.
Quote by -Alan Stern
I actually started my career in planetary science with a master's thesis on Pluto.
Quote by -Alan Stern
New Horizons isn't just visiting Pluto; it's visiting this entire region. Whatever it finds, this will be a signal moment for planetary exploration - the capstone to our first reconnaissance of the planets of our solar system.
Quote by -Alan Stern
I tend to think of Pluto and its moons as presents sitting under a Christmas tree. They're wrapped, and from Earth all we can do is look at the boxes to see whether they're light or heavy, to see if something maybe jiggles a bit inside. We're seeing intriguing things, but we really don't know what's in there.
Quote by -Alan Stern
There are lots of really interesting little planets out there in the Kuiper Belt, but Pluto's the only one that's got all the cool attributes.
Quote by -Alan Stern
One of the implications of the discovery of the Kuiper Belt and its many small planets is that many scientists now think of the solar system as having not two but three zones.
Quote by -Alan Stern
Pluto is still active four and a half billion years into its history. It was expected that small planets like Pluto would cool off long ago and not still be showing geological activity. Pluto is, in fact, showing numerous examples of geological activity on a massive scale across the planet.
Quote by -Alan Stern
Typically in science, individual scientists make up their minds about scientific fact or theory one at a time. We don't take votes. We just don't vote on quantum mechanics, the theory of relativity, why the sky is blue, or anything else.
Quote by -Alan Stern
I'm hopeful that commercial space exploration will takeoff. To really fuel the spaceflight revolution will require an investment of hundreds of billions of dollars a year, and I think that's only going to happen in the commercial sector - if there are large profits to be made.
Quote by -Alan Stern
I think if you were between maybe 6 and 16, there was nothing like Apollo, and I wonder if there can be something like that again. We'll just have to see.
Quote by -Alan Stern
At the time of Apollo 11, I was a grade-schooler, and I remember every time an Apollo mission would take place that, like a lot of little boys, I'd gather in front of the TV for hours and hours and hours with my little brother.
Quote by -Alan Stern
As a researcher, I look forward to being able to do space science in a space environment.
Quote by -Alan Stern
During one of the Apollo missions, I saw Walter Cronkite showing off the flight plan. It just mesmerized me. All this detail! That's what I wanted.
Quote by -Alan Stern
The Kuiper belt region, which I call the third zone because it lies beyond the rocky terrestrial planets and beyond the giant planets, is a bizarre frontier.
Quote by -Alan Stern
By going to Pluto, we have a chance to anchor, with real data, models of the early evolution of Earth's atmosphere.
Quote by -Alan Stern
The New Horizons Pluto mission will be the first mission to a binary object and will help us understand everything from the origin of Earth's moon to the physics of mass transfer between binary stars.
Quote by -Alan Stern
Just because Pluto or comets aren't as big as Jupiter doesn't mean they are not scientifically important - indeed, just the reverse is often true. Sometimes, great things come in small packages.
Quote by -Alan Stern
Discovering that our solar system has many more planets than we ever expected, and that most of them are ice dwarfs rather than like Earth and the other rocky terrestrials, is just another step in the revolution in viewpoint that removed the Earth from the center of the physical universe and makes Earth all the more special.
Quote by -Alan Stern
Of course Pluto is a planet: It's massive enough to have its shape controlled by gravity rather than material strength, which is the hallmark of planethood.
Quote by -Alan Stern
Just speaking for myself, I think the return of people to the Moon has a lot to offer for understanding the formation and evolution of terrestrial worlds; so would the exploration of near-Earth asteroids by people.
Quote by -Alan Stern
In science, we take large numbers of disparate facts and reduce them to see patterns. We use the patterns to reduce the amount of information. It's the reason we name species and genera and families in biology. It's also the reason we have names for certain types of geological features and so on in other fields.
Quote by -Alan Stern
A river is a river, independent of whether there are other rivers nearby. In science, we call things what they are based on their attributes, not what they're next to.
Quote by -Alan Stern
It shouldn't be so difficult to determine what a planet is. When you're watching a science fiction show like 'Star Trek' and they show up at some object in space and turn on the viewfinder, the audience and the people in the show know immediately whether it's a planet or a star or a comet or an asteroid.
Quote by -Alan Stern
No one predicted Mercury would be a planetary core with the mantle stripped off. No one predicted volcanoes on the Jovian moons, or oceans on the inside of them. I can tell you, for every single planet, huge 'we never guessed that' things.
Quote by -Alan Stern
I've been on 26 space missions; they range from suborbital to orbital to shuttle experiments to planetary missions.
Quote by -Alan Stern
It says something very deep about humans and our society, something very good about us, that we've invested our time and treasure in building a machine that can fly across three billion miles of space to explore the Pluto system.
Quote by -Alan Stern
The big lesson of planetary science is when you do a first reconnaissance of a new kind of object, you should expect the unexpected.
Quote by -Alan Stern
Going to the Kuiper Belt is like an archaeological dig into the history of the solar system.
Quote by -Alan Stern
How can an adjective in front of a noun not describe the noun? There are dwarf stars, but they're still considered stars.
Quote by -Alan Stern
If you put Earth out beyond Neptune, you wouldn't be able to call it a planet because it couldn't clear its zone.
Quote by -Alan Stern
As a planetary scientist, I don't know what else to call Pluto: It's big and round and thousands of miles wide.
Quote by -Alan Stern
I think when people see Pluto revealed by New Horizons, its satellite system, its complex surface, its atmosphere, I think they'll have a hard time saying 'That's not a planet' because it obviously will be, and I think most people are already coming to that opinion anyway, but I think that's really going to drive it home viscerally.
