About Alan Stern

Alan Stern is an American astronomer, space scientist, and science fiction author, renowned for his contributions to the exploration of the solar system, particularly the Pluto-Charon system. Born on October 1st, 1957, in Brooklyn, New York, Stern developed a passion for space at a young age. Inspired by the Apollo moon landings and books like "2001: A Space Odyssey," he decided to pursue a career in astronomy and space exploration. Stern earned his Bachelor of Science degree from the University of Florida in 1979, where he was mentored by noted planetary scientist Thomas M. Johnson Jr. He then pursued his Ph.D. at the Massachusetts Institute of Technology (MIT), under the guidance of renowned astronomer David Morrison. After completing his doctorate, Stern worked for NASA's Jet Propulsion Laboratory, where he played key roles in several missions, including Voyager 2's encounter with Neptune and Uranus. In 1990, he was appointed as the lead investigator for the Pluto-Kuiper Express mission, which unfortunately never came to fruition due to budget cuts. Determined to continue exploring the outer solar system, Stern co-led the New Horizons mission, a space probe sent by NASA to study Pluto and the Kuiper Belt. Launched in 2006, New Horizons made its historic flyby of Pluto in 2015, providing unprecedented images and data about this distant world. In addition to his work in space science, Stern is also an accomplished science fiction author. His novels, including "Carl Sagan's Cosmos: A Spacetime Odyssey" and the "Quantum Mystic" series, blend science and storytelling to engage readers of all ages in the wonders of the universe. Today, Stern continues his work as a research professor at the Southwest Research Institute (SwRI), where he leads a team investigating the origin of our solar system. His pioneering work in space exploration and his commitment to science education have left a lasting impact on our understanding of the cosmos.

Interpretations of Popular Quotes

"Everything in our solar system is a story, waiting for us to interpret it."

This quote by Alan Stern emphasizes the idea that every object within our solar system holds a narrative, a tale of its origins, evolution, and characteristics. It encourages us to observe, analyze, and deduce these stories as we explore and study the celestial bodies in our own cosmic backyard. Essentially, it invites us to delve deeper into understanding the universe's mysteries and unraveling the tales that the solar system has to tell.

"Science and engineering have this wonderful ability to turn fantasy into reality."

This quote highlights the transformative power of science and engineering, suggesting that ideas or dreams (fantasy) can be made realizable through rigorous scientific study and practical application in engineering. Essentially, it's a statement about the capacity of these disciplines to bridge the gap between imagination and tangible creation.

"Space is an environment where physics as we know it doesn't work very well."

This quote by Alan Stern suggests that our current understanding of physics, particularly as it applies to the laws of nature, does not fully explain or account for phenomena in space. Space is a unique environment where the familiar physical rules we know from Earth may not apply as expected, leading to new discoveries and revisions in our understanding of the universe's underlying principles. This insight underscores the excitement and mystery that drive scientific exploration beyond our planet.

"You can't explore the universe with a rearview mirror."

This quote by Alan Stern emphasizes the importance of looking forward and progressing in life, science, or exploration. To fully understand and appreciate the universe, one cannot solely rely on past knowledge but must push forward to discover new things and make progress. It's a call to embrace curiosity, innovation, and the pursuit of knowledge, rather than being stuck in old ideas or ways of thinking.

"The key to exploration is curiosity, passion for discovery and willingness to take calculated risks."

This quote by Alan Stern highlights the essential qualities driving exploration and discovery. Curiosity fuels our desire to seek answers about the universe and our place within it. Passion for discovery keeps us motivated during challenging times and encourages perseverance in the face of obstacles. Lastly, willingness to take calculated risks is crucial as it allows us to push boundaries, learn new things, and ultimately make progress in our quest for knowledge. In essence, the quote emphasizes that a successful exploration journey requires not only intellectual curiosity but also emotional commitment and a readiness to embrace uncertainty.

One thing scientists do is to find order among a large number of facts, and one way to do that across fields as diverse as biology, geology, physics and astronomy is through classification.

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.

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.

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.

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.

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

It's interesting - Pluto's almost a brand unto itself. It's the farthest. It's the most diminutive of the classical planets. It's been maligned by astronomers. It's always the one with all the question marks in the back of the textbook in the table. I think children identify with it because it's smaller, kind of cute.

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.

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.

The big lesson of planetary science is when you do a first reconnaissance of a new kind of object, you should expect the unexpected.
