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. - Alan Stern 1 Share Now -
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. - Alan Stern 2 Share Now -
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. - Alan Stern 3 Share Now -
We're in the space exploration business, and the outer solar system is a wild, wooly place. We haven't explored it very well. - Alan Stern 4 Share Now -
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. - Alan Stern 5 Share Now -
The big lesson of planetary science is when you do a first reconnaissance of a new kind of object, you should expect the unexpected. - Alan Stern 6 Share Now -
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. - Alan Stern 7 Share Now -
Competition-driven innovation and price pressure that commercial practices foster can only make human spaceflight ever more common and U.S. leadership in this domain ever clearer. - Alan Stern 8 Share Now -
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. - Alan Stern 9 Share Now -
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. - Alan Stern 10 Share Now -
