A Quote by David Grinspoon

I do a lot of work with NASA and am involved in research projects studying planetary evolution, Earth-like planets, and potential conditions for life elsewhere.

There are other planets besides the Earth and Mars. I'd like to remind you that studying Venus is vital to understanding life elsewhere.

David Grinspoon

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.

Alan Stern

It will be a long time, if ever, before we get to study Earth-like planets orbiting around other stars, so really, the study of Venus and Mars is the best opportunity that we have, and can imagine having anytime in the future, to understand the evolution of Earth-like planets.

David Grinspoon

The Big Bang, the formation of sars and planets, the origin and evolution of life on this planet, the advent of human consciousness and the resultant evolution of cultures - this is the story, the one story, that has the potential to unite us, because it happens to be true.

Ursula Goodenough

I keep wondering if, say, there is intelligent life on other planets, the scientists argue that something like two percent of the other planets have the conditions, the physical conditions, to support life in the way it happened here, did Christ visit each and every planet, go through the same routine, the Agony in the Garden, the Crucifixion, and so on.

Donald Barthelme

Instead of being able to look at smaller interesting research projects, I am trying to see the links between all the research NASA does. For me, that's extremely fun because I get to go play and learn about areas of science that I know nothing about.

Ellen Stofan

Given the millions of billions of Earth-like planets, life elsewhere in the Universe without a doubt, does exist. In the vastness of the Universe we are not alone.

Albert Einstein

The costs of badly-run NASA projects are paid for with cutbacks or delays in NASA projects that didn't go over budget. Hence the guilty are rewarded and the innocent are punished.

Alan Stern

A major puzzle for which nobody has an answer is this: is there some size at which the planets change their nature from water-rich planets like Neptune, to rocky planets like the Earth? We have found two planets that are the size of the Earth in radius, but they are very close to their host star, so water on the surface would evaporate away.

Geoffrey Marcy

NASA scientists announced the discovery of 50 new planets, among them what they're calling Super Earth. It's indistinguishable from regular earth until it removes its glasses.

Peter Sagal

We think that life develops spontaneously on Earth, so it must be possible for life to develop on suitable planets elsewhere in the universe. But we don't know the probability that a planet develops life.

Stephen Hawking

For actors, being successful is generally getting a job. If you can work a lot, you're really successful. If you work a lot on projects that are interesting and intelligent and great fun to be part of, then you're hugely successful. And I feel hugely successful. I can't believe that I get to be involved with the projects and the people I work with.

Anne-Marie Duff

Planets are the big bullies of the planetary system that are, that basically ignore everybody else around them. And everybody else has to deal with the planets. Those are what the planets are.

Mike Brown

You cannot study other planets without referring to Earth and without applying the techniques and the insights of Earth science. And you cannot really do a good job understanding the Earth without the insights from planetary exploration.

David Grinspoon

I'm an astrobiologist, and I come from a planetary science background, so in a very broad sense, I study the evolution of planetary environments.

David Grinspoon

Data from orbiting telescopes like NASA's Kepler Mission hint that the tally of habitable planets in our galaxy is many billion. If E.T.'s not out there, then Earth is more than merely special - it's some sort of miracle.
