The planet Mars - crimson and bright, filling our telescopes with vague intimations of almost-familiar landforms - has long formed a celestial… — David Grinspoon Copy Share Image
Earth's biosphere gave birth to humans and our thoughts, which are now reshaping its planetary cycles. A planet with brains? Fancy that. — David Grinspoon Copy Share Image

I'd been politically active ever since my parents wheeled me in a stroller in a 'ban the bomb' march in Boston in 1963. — David Grinspoon Copy Share
Through space-based climate studies, my colleagues and I have learned that a stable and comfortable climate is not something to take for granted. — David Grinspoon Copy Share
We have all this very clever technology and all these abilities to manipulate the world in all these ways, yet we are faced with… — David Grinspoon Copy Share
The planet Mars - crimson and bright, filling our telescopes with vague intimations of almost-familiar landforms - has long formed a celestial tabula rasa… — David Grinspoon Copy Share
Certainly for me, as an astrobiologist, science fiction has played an important role. One of the quandaries of our field is that we are… — David Grinspoon Copy Share
Time and time again, our species has escaped existential threats by reinventing ourselves, finding new skills not coded in our genes to survive new… — David Grinspoon Copy Share
I think that an advanced planetary civilization will modify their own planets to be more stable, to prevent asteroid impacts and dangerous climate fluctuations. — David Grinspoon Copy Share
Responsible global behaviour is ultimately an act of self-preservation of, by, and for the global beast that modern technological humanity has become. — David Grinspoon Copy Share
Venus and Mars are our next of kin: they are the two most Earth-like planets that we know about. They're the only two other… — David Grinspoon Copy Share
