Life Support Systems Quotes

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

It's such a long mission and we get to spend so much time in space... we're doing such exciting research. And I don't want to overemphasize the life science research, but as a physician the life science research that we're doing is extremely exciting.

The earth appears fragile and defenceless in the harsh environment of space and when one sees the amount of technology required to keep a human alive in that environment, one begins to feel blessed that one is an inhabitant of planet earth that supports human life.

Man is an artifact designed for space travel. He is not designed to remain in his present biologic state any more than a tadpole is designed to remain a tadpole.

We are upsetting the atmosphere upon which all life depends. In the late 80s when I began to take climate change seriously, we referred to global warming as a "slowmotion catastrophe" one we expected to kick in perhaps generations later. Instead, the signs of change have accelerated alarmingly.

Trips to Mars, the Moon, even orbit, will require that we provide astrotourists with as many comforts from home as possible, including paying each other.

Asteroids are deep-space bodies orbiting the Sun, not the Earth, and traveling to one would mean sending humans into solar orbit for the very first time. Facing those challenges of radiation, navigation and life support on a months-long trip millions of miles from home would be a perfect learning journey before a Mars trip.

As the scene of life would be more the cold emptiness of space than the warm, dense atmosphere of planets, the advantage of containing no organic material at all, so as to be independent of both these conditions, would be increasingly felt.

Research into manned spaceflight is shifting from low-Earth orbit to destinations much further away, like Mars and the asteroid belt. But society will have to invent many new technologies before it can plausibly send people to those distances.

We need to move off the planet. And Mars is the next best place.

Going underground is no answer. What kind of world would they come up to? What would they use for air? What would they use for food? ... What would they use for people?

If we go into space, we need enhancements that handle radiation and osteoporosis... or else we're dead. So what seems like an enhancement in one generation becomes life and death in another generation.

It certainly is possible to construct a moon base in such a way that crews could stay for extended periods of time.

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.

Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential.

Space X's Elon Musk wants to colonize Mars with modules where earthlings can live. My teleporting technology is the number one way those individuals will get new information, new treatments of diseases that will occur on the planet, and new food sources.

From my perspective, it's really risk management to ensure that humans have the ability to go somewhere else in case there were to be some huge disaster on Earth.

We agree that man was not created to survive in space.

Why would you need to expand beyond the solar system if you already have access to all the information you need, and you've essentially insulated yourself against a planetary apocalypse? Maybe that's enough.

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.

One of the things I think is really cool that we're testing on board the International Space Station is the water reclamation system.

Electricity, water, gas, and steam course through the walls of my building, keeping it alive.

The life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.

We need a NASA-like organization for ocean exploration, because we need to be exploring and protecting our life support systems here on Earth.

Is a one-way trip to Mars ever really seriously going to happen? Surely that's morally reprehensible. However old people are, however much they say they want to go on a one-way mission, people should be thinking about the possibility of returning.
