Wild Bill Posted March 7, 2012 Report Share Posted March 7, 2012 (edited) Well that suggests that one day we will hit the lottery, doesn't it? http://www2.jpl.nasa.gov/sl9/back2.html "NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small. In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years. To be able to better calculate the statistics, astronomers need to detect as many of the near-Earth objects as possible. It's likely that we could identify a threatening near-Earth object large enough to potentially cause catastrophic changes in the Earth's environment, and most astronomers believe that a systematic approach to studying asteroids and comets that pass close to the Earth makes good sense. It's too late for the dinosaurs, but today astonomers are conducting ever-increasing searches to identify all of the larger objects which pose an impact danger to Earth." Earlier in the article it says that the chances of a BIG asteroid are about once every million years. Meanwhile we are getting better and better about spotting them. This sort of thing however is one of the major reasons it is so important that Man colonizes Space! If we are living on the Moon, in orbiting satellites and perhaps Mars and eventually other star systems then we will never have to worry about our race becoming extinct. While all this is going on, Obama cuts American space funding so far that she is effectively no longer a player. We may someday see a Star Trek Enterprise but Captain Kirk will be Chinese!

Despite that, I wouldn't lose sleep over it. Could happen tomorrow, or in ten thousand years. But at least now we're starting to look for them, so we can see it coming...

In the future, some of these near approaches might be ideal times to hitch a ride to a different orbit 'free of charge' or perhaps capture said object into Earth's orbit for mining purposes.

Two things on this point: 1) NASA isn't the only US domestic resource for this kind of study. 2) International resources also exist in the field. NASA's budget has to be cut for practical reasons, so somebody else can pick up the slack, including Canada. Quote Link to comment Share on other sites More sharing options...

That's what I like...positive thinking! Doom folk should consider that all that has come before to bring the earth to its present state includes many millions of impacts by objects large and small. Some scientists even think that's how we got most of the earth's water. Quote Link to comment Share on other sites More sharing options...

Yep, yet another example of how Space will more likely be developed and colonized by China than by Uncle Sam. Quote Link to comment Share on other sites More sharing options...

Maybe they'll figure out how to drain the hypergolic fuels out of a Long March (in case of...you know...EMERGENCIES) before tossing a few more experimental human payloads into orbit, first.

But that could be China's major contribution...man rated flight systems are too expensive! The other day I heard Carl Sagan's assumed successor Dr. Neil Degrasse Tyson admit in public that NASA could get thousands of volunteers for a ONE WAY TRIP to Mars.

The other day I heard Carl Sagan's assumed successor Dr. Neil Degrasse Tyson admit in public that NASA could get thousands of volunteers for a ONE WAY TRIP to Mars. Of course it could. A one way trip doesn't mean you go there and die. It means you go there and stay there, in a small base/colony, spending the rest of your life exploring, building new things, doing science, etc. I don't see anyone complaining about the idea that colonists to the new world were taking a one way trip. Immigrants continue to do that on a regular basis to this very day. Quote Link to comment Share on other sites More sharing options...

As for the Red Chinese: They launched one Long March even though a technician lost a screwdriver 'somewhere in the rocket'. Another, I'm sure you're aware of, slammed into a small city. They still need a bit-o-work before Prime Time. Quote Link to comment Share on other sites More sharing options...

It means you go there and stay there, in a small base/colony, spending the rest of your life exploring, building new things, doing science, etc. Understood, but the darker interpretation was the intent, and I would volunteer as well for a one way trip even with certain death on the Red Planet in short order. Of course, far better physically qualified kamikaze astronauts exist. I don't see anyone complaining about the idea that colonists to the new world were taking a one way trip. Immigrants continue to do that on a regular basis to this very day. Agreed 100%, but Tyson was emphasizing that the risk-reward is so great for some people, they would go even when premature death was the certain outcome.

I think it's fair to say we'd be the proverbial monsters from space. If I had anything to say about it the only Earthlings I'd allow to contact another species might be the Tibetans.

In any case I don't think the universe has much to fear from our species ever hauling it's ass up out of our gravity well. I think we've seriously compromised our chances of doing so by squandering the planet's resources for the sake of living high on the hog for a handful of generations.
