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 Copy Share Image
Having a diverse suite of U.S.-manned spaceflight systems to access space is inherently robust. — Alan Stern Copy Share Image
I'm hopeful that commercial space exploration will takeoff. To really fuel the spaceflight revolution will require an investment of hundreds of billions… — Alan Stern Copy Share Image
As a researcher, I look forward to being able to do space science in a space environment. — Alan Stern Copy Share Image
As a scientist in charge of space sensors and entire space missions before I was at NASA, I myself was involved in… — Alan Stern Copy Share Image
I've been on 26 space missions; they range from suborbital to orbital to shuttle experiments to planetary missions. — Alan Stern Copy Share Image

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… — Alan Stern Copy Share Image
It used to be said that Pluto is a misfit. But now we know Earth is the misfit. This is the most populous class… — Alan Stern Copy Share Image
The Kuiper belt region, which I call the third zone because it lies beyond the rocky terrestrial planets and beyond the giant planets, is… — Alan Stern Copy Share Image
I think if you were between maybe 6 and 16, there was nothing like Apollo, and I wonder if there can be something like… — Alan Stern Copy Share Image
If you put Earth out beyond Neptune, you wouldn't be able to call it a planet because it couldn't clear its zone. — Alan Stern Copy Share Image
When we first sent missions to Jupiter, no one expected to find moons that would have active volcanoes. And I could go down a… — Alan Stern Copy Share Image
Pluto is still active four and a half billion years into its history. It was expected that small planets like Pluto would cool off… — Alan Stern Copy Share Image
The Kuiper Belt is the largest mapped structure in our planetary system, three times as big as all the territory from the sun out… — Alan Stern Copy Share Image
If two billion people wanted to watch a robot fly by Pluto, imagine what it will be like when the first humans step on… — Alan Stern Copy Share Image
To keep everyone invested in your vision, you have to back up a little bit and really analyze who the different stakeholders are and… — Alan Stern Copy Share Image
