Zitat des Tages von Rusty Schweickart:
I don't want people to spend their nights worrying about getting hit by asteroids. But I do want them to encourage their political leaders to invest in the insurance, which will allow us to prevent it from happening.
Landing on the moon was a dream that millions of kids have had for hundreds of years.
When you look at the origins and evolution of life on Earth, it's been severely affected by asteroid impacts through history.
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.
We got to the moon.
It is fantastic to think that one day we may be able to access fuel, materials and even water in space instead of digging deeper and deeper into our planet for what we need and then dragging it all up into orbit, against Earth's gravity.
Americans who read the papers or watch Jay Leno have been aware for some time now that there is a slim but real possibility - about 1 in 45,000 - that an 850-foot-long asteroid called Apophis could strike Earth with catastrophic consequences on April 13, 2036.
An asteroid can literally destroy 80 or 90 percent of the species that are alive on Earth. These are big events. I mean, this is called extinction.
No government in the world today has explicitly assigned the responsibility for planetary protection to any of its agencies.
The nice thing about asteroids is that once you've found them, and once you have a good solid orbit on them, you can predict a hundred years ahead of time whether there is a likelihood of an impact with Earth.
We are going to learn how to relate to the Earth and our own natural environment here by looking seriously at space colony ecologies.
