Buzz Aldrin Quotes

You need to live in a dome initially, but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on... So it's a fixer-upper of a planet.

Exploring and colonizing Mars can bring us new scientific understanding of climate change, of how planet-wide processes can make a warm and wet world into a barren landscape. By exploring and understanding Mars, we may gain key insights into the past and future of our own world.

You could warm Mars up, over time, with greenhouse gases.

The society of life on Mars, or the challenge of making Mars more livable, will have significant benefits on our attempts to modify and change in some ways the environment here on Earth.

Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth? Answering those mysteries may hold the key to our future.

Whether Earth was deliberately terraformed, in other words, or whether it was seeded with the spores of life from crashed comets or whether, indeed, life arose here spontaneously and accidentally, it is reasonable to hope that we might find traces of the same kind of process on Mars.

The thing that sets Mars apart is that it is the one planet that is enough like Earth that you can imagine life possibly once having taken hold there.

Pascal Lee is a true pioneer of Mars exploration.

The moon's closeness is a huge advantage: To make it habitable, we would first have to bombard it with water-ice comets, a tricky endeavor best attempted with the many resources waiting on and near Earth.

Many of the issues we face in dealing with rapid climate change are well suited to an engineering mind.

The discovery and investigation of life on other planets is likely to change many of our ideas about how life arose on the Earth and even what is life and its natural development.

It's great that people are interested in Mars.

We can't terraform yet, but we know it exists.

To unambiguously settle the questions of whether there was life on Mars, it will take scientists down on the surface.

I haven't a clue if there is life on other planets but I'd be charmed if we found a unicellular organism on Mars. It would change our whole concept of life on Earth.

Climate change is very real.

Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans.

We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects.

The best way to study Mars is with two hands, eyes and ears of a geologist, first at a moon orbiting Mars... and then on the surface.

Deliberately modifying the earth's atmosphere would be a desperate gamble with significant risks. Yet the more likely climate change is to cause devastation, the more attractive even the most perilous attempts to mitigate those changes will become.

Being at NASA and having the access to both computing capability and satellite observation capability is kind of the ideal research situation to try to understand global climate change.

Geoengineering involves humans making intentional, large-scale modifications to the Earths geophysical systems in order to change the environment.

The more we know about life out there the easier it will be to improve life down here.

This is what the Mars Science Laboratory (MSL) represents. Experimental, explorational science. Learning about Mars as a new world. Discovering new things that will tell us about the history of our solar system, help reveal the secrets of life, and continue blazing the trail that may someday be traveled by the rest of us.

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.
