A Quote by Alan Stern
There was a time when Pluto - which NASA's New Horizons spacecraft at last explored in 2015, a mission I led - was considered the last planet. We now know there are thousands of other - possibly inhabited - planets.

The planets. Now footnote, I'm including Pluto in the planets, because I think it's terrible what they did to Pluto. And it's still a planet to me. I grew up with Pluto as a planet, it will always be a planet.
We're just learning that a lot of planets are small planets, and we didn't know that before, fact is, in planetary science, objects such as Pluto and the other dwarf planets in the Kuiper Belt are considered planets and called planets in everyday discourse in scientific meetings.
I think that one of the things that will come out of the New Horizons mission is that the public will take a look, and they won't know what else to call Pluto but a planet - and a pretty exciting one.
When I started working with NASA in 1989 as part of a mission to send spacecraft to Pluto, I knew it would take at least 10-15 years to see results of my efforts.
This is in a real sense the capstone of the initial missions to explore the planets. Pluto, its moons and this part of the solar system are such mysteries that New Horizons will rewrite all of the textbooks.
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.
New Horizons is a very high-tech, small, roughly 1,000-pound spacecraft with the most powerful battery of scientific instrumentation ever brought to bear on a first reconnaissance mission.
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.
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.
When I go to America, I'm fortunate enough to stay in the nicer areas but the last time I went there - to New York last October, November - I went and explored. I went to the rough areas - to Brooklyn, Harlem, the Bronx; I walked around and you see it first-hand, what life is like out there.
It used to be said that Pluto is a misfit. But now we know Earth is the misfit. This is the most populous class of planet in our solar system and we have never sent a mission to this class.
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.
I think it's going to be remembered as the last major war on planet Earth, if we're lucky, if we maintain our foreign policy properly. It will be remembered as the last time major countries had to put people in the field and put them in harm's way. It may be the last of all human nature wars, which is a nice way to remember any kind of a war, as the last one.
All Plutophiles are based in America. If you go to other countries, they have much less of an attachment to either the existence or preservation of Pluto as a planet. Once you investigate that, you find out that Disney's dog Pluto was sketched the same year the cosmic object was discovered. And Pluto was discovered by an American.
The mission of NASA's Kepler telescope is to lift the scales from our eyes and reveal to us just how typical our home world is. Kepler operates by measuring the dimming of stars as planets pass ('transit') in front of them. It has found thousands of previously unknown worlds.
You never knew the last time you were seeing someone. You didn't know when the last argument happened, or the last time you had sex, or the last time you looked into their eyes and thanked God they were in your life.
After they were gone?
That was all you thought about.
Day and night.
