Rare, not so much lately.


The House Science Committee, chaired by Texas congressman Rep. Lamar Smith (R), welcomed John Holdren, President Barack Obama’s Director of the Office of Science and Technology, Gen. William Shelton, the commander of U.S. Air Force’s Space Command and NASA Administrator Gen. Charles F. Bolden on Tuesday morning for a hearing entitled “Threats from Space: A Review of U.S. Government Efforts to Track and Mitigate Asteroids and Meteors.”
Holdren, Shelton and Bolden emphasized that while odds of a devastating strike from an object from space are small, the consequences could be enormous. While dozens of objects a meter or more in size strike the Earth’s atmosphere every year, most burn up harmlessly in the upper limits of the stratosphere.

“We are trying very diligently, as I said before, with the president’s budget,” he said, “to be in a position where we are able to respond.” Congress charged NASA with figuring out the problem, then declined to fund the research, he said.

I prefer the old days of meteor ignorance.
The fall of the Roman Empire has been attributed to a meteor crash in Ireland. It caused Global changes that went far beyond the Roman Empire from circa 520 -540 AD. aThis was documented in a NOVA episode that I saw a few years ago. Ignorance is not an option. The eventual result would be what happened to rhe dinosuars the day they went extinct.

You go can't back home. but you can go on.

Meh, we're too busy spending trillions of dollars killing people to bother with funding stuff that could save the species as a whole. Killing people is more fun.

Amazing how much real life resembles an episode of Star Trek sometimes.

Because we have two corrupt political parties running this place and both are corporate owned and corrupt beyond our wildest imaginations. Yes instead of doing something the people either don't care , apathy... or else they continue to dream that one party is good and the other bad and if only one could just take over everything will be good. I guess thats what they mean by the "American dream".

Are you seriously going to pull that shit? Crawling out from under your rock, I guess you're proud of yourself. My grand daughter, who's 9 years old now, is Black. She is the future as I see it. Another 40 years and most humans will be of a tanned complexion. Tell you what, Under a Rock boy, how about you come by my neck of the woods and talk that way. Think you have the stones, Under My Rock boy?

And that licence plate is blue? Irony is Ironical.

Racism is still considered to be popular and populist. It's a freaking embarrassment to humanity at large.
Poking fun at racism in a fierce manner, talking about it, and exposing it is the best way.

Kind of a razor's edge, but getting edgy and in somebody's face about it is completely deserved.

'PG's statement was not funny or cute. I like poking fun at it.

Deviating the thread back onto John's initial topic for a moment:

I wonder how much of the decision to cut program funding has to do with the fact that the success rate of numerous amateur astronomers who volunteer their time tracking NEOs and earth crossers rivals that of the big observatories?

On any given night there's a fair amount of glass pointed at the cosmos and not all of it is commercial or government-managed. Odds are those telescopes will catch whatever it is that can hurt us if it's transitory or periodic in nature.

A nearby GRB or wandering black hole? We won't detect the former until the wave front arrives at Earth and in the case of the latter there's not a damned thing we can do about it.

The thing is, while these guys are really good at what they do, they do not have the equipment that NASA does. Hm, maybe this is something Hams could do. Get an Experimental license (no expiration) and run a radar station to monitor the near Earth field for intruding bodies. There's SARA and the work they do is pretty incredible for amateurs.


On any given night there's a fair amount of glass pointed at the cosmos and not all of it is commercial or government-managed. Odds are those telescopes will catch whatever it is that can hurt us if it's transitory or periodic in nature.

There are some that have extremely low albedos and are hard to see. Those are likely to go unobserved by optical telescopes.


A nearby GRB or wandering black hole? We won't detect the former until the wave front arrives at Earth and in the case of the latter there's not a damned thing we can do about it.

Faster Than Light communications might be able to warn us of GRBs. I know, I know, Einstein claims that nothing travels faster than light. Yet, there are organisms that can detect each other spontaneously at great distances in times that have been measured as FTL. Then there's this:



Quantum entanglement is a form of quantum superposition (http://en.wikipedia.org/wiki/Quantum_superposition). When a measurement (http://en.wikipedia.org/wiki/Measurement#Quantum_mechanics) is made and it causes one member of such a pair to take on a definite value (e.g., clockwise spin), the other member of this entangled pair will at any subsequent time[6] (http://en.wikipedia.org/wiki/Spooky_action#cite_note-6) be found to have taken the appropriately correlated value (e.g., counterclockwise spin). Thus, there is a correlation between the results of measurements performed on entangled pairs, and this correlation is observed even though the entangled pair may have been separated by arbitrarily large distances.[7] (http://en.wikipedia.org/wiki/Spooky_action#cite_note-7)In Quantum entanglement, part of the transfer happens instantaneously. [8] (http://en.wikipedia.org/wiki/Spooky_action#cite_note-8) Repeated experiments have verified that this works even when the measurements are performed more quickly than light could travel between the sites of measurement: there's no slower-than-light influence that can pass between the entangled particles. [9] (http://en.wikipedia.org/wiki/Spooky_action#cite_note-9) Recent experiments have shown that this transfer occurs at least 10000 times faster than the speed of light.
Ein Called it Spooky Action (http://en.wikipedia.org/wiki/Spooky_action)


Place these on a probe or monitoring spacecraft and it is possible to get advance data sent to earth in binary or just to toggle an idiot light here.

As far as a black hole, the best we can do is leave the planet if one is headed our way. That means putting a lot more money into NASA or Private Spaceflight Companies rather than less.

It's not like they'll have the available data to compute the threat of the NEO that they observe. For at least that much NASA will still have to function.

The problem with Quantum Entanglement is that Heisenberg's Uncertainty Principle makes it impossible to use it to transfer information.

Though I think we'd learn a lot from simply exploring concepts to deflect 'killer asteroids'.. based on my limited knowledge of the subject, it seems like if one of these earth killers was heading for earth, we'd be doomed no matter what efforts we put into stopping it. I think I'd rather just not know, all things being equal.

Correct. Blow it up and the mass still remains on trajectory, with all the inherent kinetic energy.

If the asteroid contains Teh Oyal or some other precious commodity, best to deflect the thing into a parking orbit and give everyone something else to fight over.

True, but if the asteroid is discovered while it's still far enough away, a properly applied nuke—one that imparts energy to it without causing it to break up—may deflect its trajectory enough to cause it to miss us. It's a risky maneuver with only limited chance of success but if the only other option is a direct hit, it would be worth a try.

The problem isn't so much as total kinetic energy, but rather the kinetic energy of each object. 10 objects, with 1 KJoule of energy, impacting a steel plate will deform the steel plate's surface a bit. 1 object, with 10KJoule's of energy will punch a hole through it.

We would need to not have a single large event, rather than 10 smaller events. It's the boiling of the oceans combined with the dust kickup from a single large impact to be concerned about.

I remember watching a TV episode of Superman (1950's) when I was a kid where there was a massive asteroid headed right for the city of "Metropolis". The city, and possible the entire earth, was doomed but fortunately Superman jumped into the aire, flew into space, and smashed into it knocking it off course. But, by knocking it off course he pushed it in such a way where it was still out there but orbiting the earth and was still in danger of crashing into the earth, according to the actor playing an astronomer. So, they gave Superman some sort of atomic bomb and he flew it up to the asteroid and blew the crap out of it and saved the earth from certain destruction.

Now, if we can only find Superman we might be safe from asteroids and other cosmic debris.

Atari had a game room for employees off site that was open until 1 AM most days. They had all of their commercial machines in there you could play for free. Brand eX #1 and I used to go there all the time because that person was from Sunnyvale (home of Atari).
