How NASA Will Bomb the Moon To Find Water

mattnyc99 writes "A few weeks ago we got first word of NASA's plan to crash a spacecraft into the moon next February. The new issue of Popular Mechanics has an in-depth look at the Lunar Crater Observation and Sensing Satellite and its low-cost, lightning-fast mission prep — even if delays have pushed it to late February or early March. Quoting: 'Andrews had no budget for an expensive lander to seek water, and conditions in the eternally dark polar craters would kill rovers, with temperatures close to minus 300 F. Instead, Blue Ice and its partners at Northrop Grumman came up with a concept to bring the lunar floor out in the open.... Since engineering precision hardware would break the budget, the LCROSS team had to make existing components work together.'"

That said I agree with your point - this will have an utterly negligible affect on the orbital dynamics of the Moon.

Earth's rotation is more closely linked to the moon. Without the moon, we'd complete a day's rotation in something like 48 days instead (Google that to be sure).

But blowing up something on the moon shouldn't be blowing up the moon... unless we're following Armageddon physics all of a sudden.

I though it was well within our current power to fuck up the Earth's orbit. Given that the whole time I was growing up we were constantly told we could "blow up the Earth 20 gazillion times over" I was under the impression that we could fairly easily knock it off kilter.

I mean, several tens of dozens of multi-megaton explosions sure as hell sounds like a lot of energy to me. I didn't think it would take much of a 'bump' to basically bugger everything.

I didn't read this particular article, but I think the idea here is to examine the dust that is ejected, most likely using various spectrometers.

This was done with a comet some time ago, at a far greater distance.

It's similar to the high tech way of identifying mysterious substances in a modern laboratory, just on a larger scale and at a much greater distance.

I would imagine that the "bomb" would be primarily of the kinetic energy variety.

Re:Earth's Orbit?

[gstoddart]

Math. You're doing it wrong.

I'm doing absolutely no maths whatsoever.

I'm legitimately asking (because nobody ever really quantified what "blow up the Earth several times over" means) whether or not we could. Having been around in the 70's and 80's as a kid, you'd think we'd have been able to pulverize the whole planet by now.

I have no idea of how to wrap my head around how much energy would be required to cause a change in orbit, let alone in relation to what we could actually produce.

Let's face it, a large number of megatons worth of denotation, many times over, eventually becomes a pure abstraction you can't compare to anything else.

Obviously, you're asserting we can't, you're just not very helpful either. :-P

When people say we could blow up the entire Earth, they really mean we could cover the surface of the Earth in nuclear explosions. It would kill all of us, but the Earth wouldn't care. It would just keep trundling along as ever.

Some maths: Suppose we wanted to increase the speed of the Earth by 1m/s. Kinetic energy = mass * speed^2, so (as the mass of the Earth is 5.9736*10^24 kg) we'd need 5.9736*10^24 joules. A megaton explosion is 4.184*10^15 J, so we'd need the equivalent of about a billion megatonnes of TNT. That's about one hundred million pretty big nukes (assuming all the energy of the nukes goes into the Earth's movement, which it wouldn't). And that's just to accelerate the Earth by 1m/s. And when you add to that the fact that the Earth's orbit is stable (so we need a lot of movement to do any real damage), you can see how little we could really do.

Hope that makes sense!

It's equivalent to one million tons of TNT.

We know the energy involved.
Bust out a calculator.

Look up the masses of the sun and Earth.

Go overboard and use overestimates for the amount of nukes we have, round down on the masses, and assume all the energy is directed perfectly and results in pushing the earth away from the sun.

Then laugh.

Re:Earth's Orbit?

[MarchHare]

Your computation actually has some errors in it. The amount of energy required to increase the earth's speed from what it is (about 30,000 m/s) by 1 m/s is not the same as the amount of enery needed to increase it from 0 to 1 m/s (which is what you computed, except that you also made a mistake by a factor of 2).

A better estimate (with same mass, but increasing the speed from 30,000 m/s to 30,001 m/s) yields
1.7921e29 joules needed. That's 5 orders of magnitude greater than your solution.

I once computed that to remove the top 1cm of topsoil or water from all the worlds land masses and oceans, and throw them out into outer space at escape velocity, we'd need to perfectly use the energy of 100 billions bombs like Hiroshima's. I wanted to see whether exploding a planet like the Death Star does in Episode 4 was realistic. It isn't. At escape velocity, the chunks of the planets would take 6 minutes to double the planet's volume (so the explosion would look very very slow).

Re:Earth's Orbit?

[Cecil]

Even if we could blow up the Earth several times over (we can't), doing that requires orders of magnitude less energy than actually changing the Earth's orbit. If you blow up the Earth into millions of tiny little chunks, all those tiny little chunks will keep happily orbiting the sun (See: Asteroid belt) at very nearly the current speed and path that the Earth currently travels.

An object with the mass of the Earth, travelling through space at the speed that it is, has an unbelievable amount of kinetic energy. We can divide it up into smaller pieces, but actually changing the amount of orbital energy in the entire mass is rather far beyond us.

er... I was accelerating it radially, at midsummer or midwinter? *wipes brow*

I was actually wondering about this at the time. I took my reference frame to be ours (rather than assuming the Sun is stationary). I have a feeling this wasn't valid, but could someone enlighten me?

Re:Earth's Orbit?

[Anonymous Coward]

That said I agree with your point - this will have an utterly negligible affect on the orbital dynamics of the Moon.

So what you are saying is that they will need a much, much larger explosion? I agree.

NASA should be using something Tzar-sized in a "bunker buster" configuration to cause something about 10^16 Tzar sized to be fired deep into the Moon's crust before being detonated.

It might be difficult to keep the larger of the two bombs in working condition under such stresses. I think it could be done by encasing it in a massive steel sphere and then packing the sphere insulative, shock-absorbing material. I think a large quantity of kittens would work.

I'm not sure how cohesive the material ejected from the surface would be, but they should try to aim it at Kansas.

Re:Earth's Orbit?

[kmac06]

I concur with your original analysis. I think it is valid to use our reference frame rather than the Sun's, since we would be essentially be firing a huge rocket.

It's like a car vs rocket. The energy it takes to change the velocity of a car depends on it's current velocity, essentially because you're pushing against a stationary object (the earth) while you are moving. The energy to change the velocity of a rocket does not depend on it's current velocity (neglecting air resistance). This is because it pushes against it's own fuel.

If this seems like a contradiction in terms of conservation of energy, consider this. At initial velocity, the fuel in the rocket has some momentum and energy relative to a fixed object (the earth). If the rocket pushes against the fuel to accelerate it, then the fuel has less momentum and energy relative to the fixed object. It is this 'extra' energy that makes up the difference. It's not 'free' energy, because the rocket had to accelerate that fuel in the first place.

For the pushing the earth analogy, you are 'using up' the energy of the nuclear fuel when you use it to speed up the earth, by making the fuel travel slower relative to the sun at the end.

And now to finish confusing people, if you are attempting to slow down the earth rather than accelerate it, you can actually get energy out of that.

I was reading an article few minutes backpertinent to this discussion. Check out
http://www.deepastronomy.com/how-to-destroy-earth-with-a-coffee-can.html

To completely vaporize the Earth, you'll need to overcome the Gravitational Binding Energy of all of the atoms that hold the planet together. This amounts to 224,000,000,000,000,000,000,000,000,000,000 Joules. If you are uninspired, as so many evil geniuses are (sorry guys, but you know you are), then you probably went to ThermoNuclear Depot and tried to buy some nuclear weapons to do the job. Stan, the nice guy who works in that department with the bright red vest wearing a button that says 'Get Bent', told you that it would take roughly 107,000,000,000,000 bombs to vaporize the planet (he gets about three guys a week asking for the same thing). He politely and cheerfully sends you to the Special Order department to fill out one of their forms (they don't keep that many in stock, and they are seasonal). Most evil geniuses are averse to filling out forms, so you left. Here's the math: 224,000,000,000,000,000,000,000,000,000,000 Joules per planet divided by 2,100,000,000,000,000,000 Joules per nuclear bomb = 107,000,000,000,000 nuclear bombs per planet.

Sorry - you need to SQUARE the velocity. That makes a difference of a factor of around 320,000 times larger in the KE needed....

The Earth's velocity is around 160,000 m/s; the factor you missed is the difference between 160,000 m/s squared and 160,001 m/s squared (to increase the velocity by 1 m/s).

Currently, the moon is slowing moving away from the Earth. Simple physics tell us that bombing it will push out its orbit... that will affect the tides and wind here on earth... seems like a bad idea.

The moon is smacked by meteors all the time, many much larger than any space probe could ever be. After all, it has a nasty case of acne scars. Most meteors are still usually too small to make any detectable difference. It's probably been hit by some biggies that perhaps could alter its orbit, but the average direction of the smackage either averages out or has a tendency already reflected in its current orbit. The largest impacts that created the round dark sea-like areas appear to have happened fairly soon after its formation.

In Red Mars by Ben Bova, they accidentally wrap a space elevator cable around the planet Mars...this does indeed release some water, but anything within a couple miles of the cable is flattened.

In an episode of the Adventures of the Galaxy Rangers, a supercollider is set up to encircle a small moon...the resulting collision of the particles tears the moon apart.

The Author was Kim Stanley Robinson, not Ben Bova. And the space elevator wrapping around Mars had no connection with water. We could nuke the moon with everything we got and it wouldn't do jack to our eco-system. I really hope these kinds of comments are sarcastic, noodley one help us if they aren't.

Re:Apparent issues

[lymond01]

Right...keep getting those two authors confused. Thanks for the factcheck. While I didn't read Blue Mars, I was under the impression the cable had broken open a bunch of underground watersheds...I figured that would play into the "blueing" of Mars.

And yes, everything was tongue-in-cheek. It hurts a little inside to suggest you'd think otherwise (Adventures of the Galaxy Rangers? Sheesh.).

Re:Apparent issues

[ContraMatter]

The series is actually quite brilliant if a bit long winded, but most of the water came from icey commets and rocks they divert to burn off in the atmosphere. Some water comes from underground sources. My appologies, I sometimes take things too literally, and have met too many people in the past who's education in certain areas are sadly lacking. Here's to our amazing education system! Woot.

You know, while I'm generally in favor of the metric system over imperial, I've never cared nearly so much about the Celsius v. Fahrenheit debate.

Fahrenheit makes more sense in day to day contexts. 0 is very cold, 100 is very hot (both from a human experience point of view), and you have more precision on the temperatures in between. Now in this particular case it's so cold that it doesn't really matter; if I told you it was -184 C, or -300 F it wouldn't really change the fact that you can't conceive of the temperature as anything but "really, really cold".

Besides, who are you trying to chastise? The temperature was given in a quote from the article. Would you prefer Slashdot editors mangle quotes to conform to your prejudices?

Fahrenheit is a superior unit of measure. Each degree corresponds to the difference in temperature a human can sense. Celsius is arbitrary and much less precise.

The metric system got everything right except temperature.

Now in this particular case it's so cold that it doesn't really matter; if I told you it was -184 C, or -300 F it wouldn't really change the fact that you can't conceive of the temperature as anything but "really, really cold".

It only makes sense because you're used to it.

In Celsius 0 is also very cold, but at the same time more meaningfull ("what will happen to water today?" or "what can fall from the sky today?"). Same with 100, also very hot, and usefull even in the kitchen. (and both 0 and 100 can be easily calibrated on Earth). And no, 100 Fahrenheit isn't very usefull medically - it's a temperature of somebody with severe fewer; if it would be "normal"/"border one" - I would agree with that one.

As for precision - BS, even Celsius scale has way more precision than we need in day-to-day life; people usually think in terms such as "it's around zero today", "it's just above zero", "it's around 5", "a bit below 10", "low dozens" and so on...

You're probably Western European to say something like that. 0c is mildly cool. "Cold" is when dry ice starts forming frost on the ground. 8)

No, sorry, at least for those in the northern 2/3 of North America, Fahrenheit works better for day-to-day considerations of human comfort (and perception of environmental "hot" and "cold"). 0 degrees F is painfully cold on exposed flesh. 100 F is dangerously hot (unless you're in one of the freakishly-low-humidity regions and you're hydrated well enough to not die of dehydration trying to sweat off the heat.)

("what will happen to water today?" or "what can fall from the sky today?")

What happens to water today is a factor, too, but that makes only the bottom end of the 0-100 scale relevant to daily experience (unless you experience storms of boiling steam where you live). And whether water falls out of the sky as ice or water is secondary to whether water falls out of the sky at all, which is only indirectly related to temperature (i.e., dew point).

As to the precision issue, you can't dispute that 1 degree Celsius is a broader temperature differential than 1 degree Fahrenheit. So, for as little as it matters on a day-to-day basis, 1/10 degree is more precise in Fahrenheit than Celsius.

Re:Fahrenheit?

There's a very simple and accepted way to adjust quotes to accurately reflect what a person was saying. you simply put the adjusted/added words within brackets or an elipses within brackets if you are removing something. This is done by... well by basically every major news organization in the english speaking world. So now, I don't "prefer Slashdot editors mangle quotes", I prefer that they adjust them to make their meaning clear.

As an aside, 0 F being very very cold and 100 F being very very hot might work for some places. But I have walked to school when the wind chill was in the -50s F and the true temp was in the -20s F. I've also had the pleasure of experiencing 114 F (same location). So when the actual temperature range is 64% larger than the range the system was designed for, that makes things a little more difficult. Of course, Celsius has the same problem on the negative end, but I'm just saying.

Celsius vs Kelvin doesn't matter when talking about 10,000,000 degrees, as they only differ in the zero point by a few hundred degrees, which is not significant on that range. 10,000,000 degrees Fahrenheit on the other hand is only about 5.5 million degrees Celsius which *is* a significant difference (almost 50%).

What is more day-to-day context than the water cycle? 0 = Solid/Ice, 100 = Boiling/Gas. If you can't figure out the in-betweens you're too dim to comprehend integers.

What is the F scale built on? 0 signifies nothing, there are no significant numbers that correspond to anything in a human context. It makes perfect sense that 32 is freezing and 212 is boiling? And whats more intuitive and useful than an average body temperature of 98.6F?

0 degrees F is painfully cold on exposed flesh. 100 F is dangerously hot (unless you're in one of the freakishly-low-humidity regions and you're hydrated well enough to not die of dehydration trying to sweat off the heat.)

0C is chilly, not 'mildy cool'. -10 is cold, -20 is very cold. -30 is damn cold. -40 is I'm not going outside.
+10 is cool, +20 is warm, +30 is hot, +40 is "I'm not coming out the shade/water/airconditioning."

As to the precision issue, you can't dispute that 1 degree Celsius is a broader temperature differential than 1 degree Fahrenheit. So, for as little as it matters on a day-to-day basis, 1/10 degree is more precise in Fahrenheit than Celsius.

Other than when taking my own temperature I don't care about the decimal point. Hell, for day to day living, I don't even care about the exact degree. I live by ranges. To me, 12C is pretty much the same as 14C. 21C is pretty much the same as 23C. Etc.

Indeed, the Fahrenheit system was based on the coldest (0F, ice and salt) and hottest (100F, armpit) temperatures that Fahrenheit could concoct from his immediate surroundings, without resorting to extremes like fire. Therefore it's a comfortably human-sized temperature scale. I've only been on this side of the Atlantic for 2 months and I'm already adapting to it nicely.

Re:Fahrenheit?

[Guppy06]

"what will happen to water today?"

Before or after the salt trucks come through?

"what can fall from the sky today?"

Because it's not possible for different layers of air to be at different temperatures?

"Same with 100, also very hot, and usefull even in the kitchen."

No, it's not. When was the last time you stuck a thermometer into a liquid on the stove in the process of cooking? Does your range have temperatures on the burner controls? Boiling water isn't useful in the kitchen because it's "exactly 100 degrees Celsius" (which it isn't), but because it's at a constant temperature, regardless of what number you chose to associate with it. And even then, stovetop recipes have to be adjusted for altitude ("How high am I above sea level?" is a question asked more often than "What temperature is this boiling water?")

"(and both 0 and 100 can be easily calibrated on Earth)"

No, they can't. Celsius is defined as a linear offset to kelvin, period. At a "standard" atmospheric pressure of 101 325 Pa, water boils at about 99.974 C (and this is a mathematical approximation based on experimental data). So even if you had a barometer that was accurate to 1 Pa absolute, arbitrarily declaring the saturation temperature in the room at the time as "100 C" is no more accurate than declaring it to be "212 F" (and at least there the approximately 180 F temperature difference between freezing and boiling is easier to subdivide geometrically).

As a linear offset to thermodynamic temperature, no mere mortal has the equipment to properly calibrate their thermometer (Celsius or Fahrenheit) in their kitchen.

"And no, 100 Fahrenheit isn't very usefull medically - it's a temperature of somebody with severe fewer;"

With respect to measuring human body temperature, Fahrenheit is useful medically by simple virtue of being more granular. Assuming a normal body temperature of 98.6 F (37 C), a fever of 100 F is still less than 1 C above normal. 38 C is 100.4 F.

"BS, even Celsius scale has way more precision than we need in day-to-day life"

Then the adjustments on your thermostat are marked only to the nearest 5 C? If it's more granular than you need, then put your money where your mouth is and set your thermostat up another 2 C.

"it's just above zero", "it's around 5", "a bit below 10"

So the "metric" temperature scale is one that people "feel" in units of 5 rather than 10? In Fahrenheit, that would be "in the 30's," "in the 40's" and "in the 50's," respectively.

While 100F body temp isn't considered normal, it isn't severe - it is low grade fever. You're usually not bed ridden at the temp. Once you're above 102 to 104 - that is considered moderate fever. Above 105 F it is pretty bad and much above 107F you turn into an average anonymous Slash dot poster. http://www.med.umich.edu/1libr/pa/pa_feverpho_hhg.htm

Fahrenheit has approx. twice as many divisions between water freezing and boiling, so in effect given the same number of significant digits, a temperature in Fahrenheit is more "precise" than one given in Celsius, but your point that this precision is more than what is needed in everyday life is quite valid. Also, given the ease of conversion between Celsius and the even more useful (in scientific circles) Kelvin scales, Celsius has the edge.

It's exactly the same thing as Celsius except for where the two points are placed.

Well, yes -- exactly the same thing except for where the two points are placed.

Actually, Fahrenheit makes even more sense imo, 0 is the freezing point of a brine, 32, the freezing point of water is 1/3rd of the way to body temperature. The boiling point of water is just over six times.

Imagine the dial of a clock, freezing of saline is at the top, water at 2:00, body temp at the bottom (6:00) and boiling water all the way around at 12:00. (Room temp would be around 4:00.) How elegant?

Human habitable nicely scales between 0 and 100, with the logical average of 50 having a certain balance to it. (It's about 10 in Celsius, with the range from -20 to 40...)

Even the sun's surface is just under a round 10,000 Fahrenheit, how much nicer can you get? (It's 5526 in Celsius.)

Metric is so much nicer for other measurements, especially when scaling, but that just doesn't seem to apply to centigrade for temperatures.

PS: I totally agree in terms of precision, people generally can't discern a different of four degrees Fahrenheit, whereas Fahrenheit multiplied Romer's original scale times four.

Wow, you must live in one of those perpetually warm places I've heard about - the French riviera or Florida, maybe. I live at latitude 63 degrees North, and can assure you that "very cold" begins at around -30C. In fact, 0 Celsius is regarded as quite a warm day in winter here.
I can also assure you that there is a palpable difference between -20C and -30C, and a similarly palpable difference between -30C and -40C. If you go outside (properly attired) at -30C, there is no chance of thinking mistakenly that it's -40C or -20C.
OK, in summer 0C would be cold, but we had several days in June and July this year when it did not go above +10C.

Re:Fahrenheit?

[markjhood2003]

The Fahrenheit scale was specifically designed to be useful for describing climatic temperatures, 0 being about the coldest and 100 about the hottest temperatures experienced in the temperate climate zones on planet Earth. It makes a hell of a lot more sense for that purpose than Celsius. It gets a lot colder than 0 Celsius in most parts of the world, and never gets as hot as 100, so the useful range for describing today's current weather is rather restricted in Celsius.

Re:Fahrenheit?

[Fred Ferrigno]

"Zero degrees" also changes when you talk about Kelvin but no one has a problem with that. The magnitude of a degree in Celsius is set by how many degrees you want to put between boiling and melting: 100 in the case of Celsius or 180 in the case of Fahrenheit. There is no real benefit to picking 180 instead of 100 or vice-versa.

Contrast both Fahrenheit and Celsius with the foot, which was originally just the size of the foot of the person doing the measuring. Eventually it was standardized to be a specific length more or less pulled out of thin air. The foot then subdivides into inches in base 12, which isn't commonly used for anything else except imperial measurements.

Fahrenheit shares the benefits common to metric units, being independently replicable and subdivided in base 10. It could have just as easily been a metric unit as Celsius.

Re:Fahrenheit?

[camperdave]

I agree with that the metric system is superior than imperial. However, this is simply because of the base 10 conversions.

It's more than using base 10 instead of fractions. Practically every imperial measurement requires two units of measure. Short lengths are in feet and inches. Weights are in pounds and ounces. Plus there are conflicting standards for these measurements. For example, a pound of gold weighs less than a pound of sand, but an ounce of gold weighs more than an ounce of sand. A mile on a map measures 5280 feet, 1/8 inches if you measure by ruler. Why? Because precious metals are measured in troy pounds and ounces and ordinary materials are measured in avoirdupois pounds and ounces. Distances on maps are measured in survey feet and inches, which are different than standard feet and inches.

The really dense thing about all this is that all of these weights and measures are DEFINED in terms of the metric system. A standard inch is 25.4mm by definition. A survey inch is 25.4000508 mm by definition (technically one inch U.S. survey measure is defined so that 39.37 inches is exactly 1 meter). The pound avoirdupois, which forms the basis of the U.S. customary system of mass, is defined as exactly 453.59237 grams.

Re:Fahrenheit?

[sznupi]

When it comes to climatic usage as in "usage by climatalogists", well...I'd put a wild guess that they don't have any issues with Celsius.

As for day-to-day usage - one could still argue that 0 in Celsius is still quite adequate; tells you when you should start to dress really warm. And at the point of -18 degrees Celsius/0 Fahrenheit you should be not only dressed warm - you should start to be carefull. So Fahrenheit is sort of borderline here again, just like with 100.

Re:Fahrenheit?

[sznupi]

Actually - central Europe. Extremities I witnessed were 37 degress C in summer and -28 in winter (daytime). By "really cold" I meant more "start to dress properly" (or alternativelly - "you might start to think about dressing more lightly" in pre-spring), sort of borderline temperature which sends a clear message.

Re:Fahrenheit?

[sznupi]

Thanks for explanation, it might start to make more sense to me... (right now I basically only know how much is -40 and 100; when communicating with somebody using F it's usually Google calculator for me...)

But as to making more sense - what's easier to aquire, brine or simply water? Freezing point of water is of course quite easy - but why use something different than in the first case (brine) and why put 32 degrees between those two points? Temperature of human body...not necceserilly straightforward. Boling water - piece of cake.

So...take on of the most abundant substances on Earth, freeze it, boil it, divide by 100. Makes sense.

Re:Fahrenheit?

[sznupi]

Well, I look at 37,7 (and even somewhat lower) as "requiring attention" already... (TBH this perception of mine might be influenced by the thing that due to medical reasons I was carefull in the past about high temperature)

BTW, temperature of human body, when measured in C, is ALWAYS given with first decimal number. So it's actually quite precise.

Re:Fahrenheit?

[RJFerret]

Hmm, around here that's what we put on the roads in the winter, well, we put the salt part, nature puts the water part. Above 0 Fahrenheit the roads are safe to travel, in the negatives, icy... Ice melt products work above 0 on the sidewalk, below 0 you are just wasting time.

I've never really had use for the freezing point of water. I mean, below 50 I need a sweatshirt, below 40 I need a jacket.

Oh, and for the most abundant substance on Earth, have you tasted the oceans recently? Try freezing it! ;-)

And I apologize for going back to the earlier post about what falls from the sky, 32 degrees (or 0 as the case may be) doesn't affect what is falling from the sky. It was 90 degrees here the other day when ice fell. The upper atmosphere circulation conditions in no way relate to down on the ground. I have been in liquid rain below 30 degrees (which froze in my hair) and had snow up to 36, which promptly melts.

Lastly a friend in Canada has a stereotypical joke for any differences in language, clothing, culture, "double it and add 32"--might save a trip to google's calculator! Heh...

Re:Fahrenheit?

[Darren Foong]

I've no idea why the difference between the freezing and boiling points of water are divided into 180 divisions, unlike the Celsius scale. To me, 100 is much more "natural"...

I never understood the Fahrenheit scale; the Celsius scale is straightforward. It's like percentages. 0 C is "cold as ice", 100 is "hot as boiling water", and negative temperatures are way too cold.

Introduce the scales to a three-year old kid. He'd probably be more used to the Celsius scale.

And obviously the thermodynamic (K) scale is too big for normal purposes....

Re:Fahrenheit?

[toddestan]

Perhaps I'm used to Fahrenheit, but it seems more natural to me. The point where water boils isn't really meaningful to me on a day-to-day basis, as my body really can't differentiate 80C from 100C from 200C, as those are all well within the "you're going to get burned" territory. If instead, you were to make a scale where you put the outside air temperature where it starts to get dangerously cold at 0 degrees, and where the outside air temperature starts to get dangerously hot at 100 degrees, you'd pretty much have the Fahrenheit scale. That's why it seems more natural, especially since temeratures much outside of that range simply become "damn hot" and "damn cold" to the human body. I would guess that a three-year old would find that more natural too, as most three year olds aren't really going to have a good concept of how hot boiling water is (and depending on where they live, how cold ice is too).

Re:Fahrenheit?

[toddestan]

Actually, Fahrenhiet is easier to calibrate. Mix salt into a water/ice mix until the solution is saturated. That's 0. Measure when water freezes, that's 32. Now measure your body temp. Call that 96. Now, you have a thermometer with marks at 0, 32, and 96. You'll note that these are 32 and 64 degrees apart, or nice powers of 2, so you can keep splitting the difference in half to fill out the scale with whole numbers. The boiling point of water is at 212 degrees, or 180 degrees away from the freezing point, which is another convienent number to divide.

BTW, temperature of human body, when measured in C, is ALWAYS given with first decimal number. So it's actually quite precise.

Same with Fahrenheit - where I grew up, 98.6 F is "normal" temperature.

But then the accuracy all depends on calibration of the thermometer - doubt if a C reading is calibrated any closer than a F thermometer. :-)

Whereas instead of very cold, 0 degrees Celcius is the coldness that causes water to freeze. And instead of very hot, 100 degrees Celcius is the temperature at which water boils.

Re:Fahrenheit?

[MikeBabcock]

Last I checked we had decimals (you even used them in your degree values). My thermostat has .5 degree increments which gives me plenty of accuracy.

Re:Fahrenheit?

[Guppy06]

"Last I checked we had decimals (you even used them in your degree values)."

As does the Fahrenheit scale. SI and its ilk don't have a monopoly on decimal numbers.

But the point is that there are always applications for which one particular measurement system is ill-suited; where 1 is too big and 0.1 is too small to be useful. In the example of human body temperature, a fever of 1 C would leave you bed-ridden while 0.1 C would hardly be noticed. Measuring on the Fahrenheit scale gives you a middle ground between "healthy" and "flat on your ass" without the need to go down a whole order of magnitude.

"My thermostat has .5 degree increments which gives me plenty of accuracy."

I'd wager that Celsius isn't the only temperature scale your thermostat can use, then.

Re:Fahrenheit?

[Anonymous Coward]

Starting to get off-topic, but I'll bite.

No, the system was NOT DEFINED in terms of metric. The Imperial system was here first. It is shown as conversions to metric. That way a metric person won't think a 100 lb. person is morbidly obese or a 4 foot person is too tall to fit through most doorways.

If you were in the imperial world, you would think that the metric system was based on the imperial system because of how conversions are shown.

Re:Fahrenheit?

[camperdave]

No, the system was NOT DEFINED in terms of metric.

I agree that they did not start off that way, but since the Mendenhall Order of 1893 the fundamental standards of length and mass of the United States changed from the customary standards based on those of England to metric standards.

Re:Fahrenheit?

[Anonymous Coward]

You spread BS about human body temperature measurements.

In Celsius a normal human temperature is NOT 37 degrees, but 36.6 or 36.7 depending on a country.

And since most current weather forecasts give a range of temperatures I highly doubt there's a single human in the world that can detect a difference between 27-29C and 77-82F. // Artem S. Tashkinov

Re:Fahrenheit?

[Guppy06]

"In Celsius a normal human temperature is NOT 37 degrees, but 36.6 or 36.7 depending on a country."

And that changes the fact that 1 degree is too large and 1 decidegree is too small to be particularly meaningful units of measuring that temperature how?

"And since most current weather forecasts give a range of temperatures"

Because they're forecasts. The numbers given are as precise as they can predict at the given time.

"I highly doubt there's a single human in the world that can detect a difference between 27-29C and 77-82F."

Then I'll issue you the same challenge I issued the parent: bump up your thermostat 2 degrees Celsius. It's August and oil is expensive; provided you're not in the southern hemisphere, you'd be saving a few kW h by increasing the temperature in your home by an amount you claim you cannot detect.

A Realistic Plan for World Peace
a.k.a
Nuke the Moon
by Frank J. (originally written August 15th, 2002)

"Gotta nuke something."
-20th century philosopher Nelson Muntz

World peace cannot be achieved by sitting around on our duffs singing hippy songs to the moon. Peace can only be achieved through excessive acts of seemingly mindless violence. Who do bullies pick on in the playground? The giant, crazy looking guy who looks ready to snap and kill the person nearest or some harmless looking weenie who appears to do anything to avoid conflict? People pick on the weenie because people like to start fights they think they can win. In the same way, people will continue to attack America and our interests when they get the idea that they can piss off America without us immediately eradicating them and everyone around them in the most painful way possible.

Now, if I were president, here's what I would do. Next time some country does something we don't take a pining too, such as supporting terrorism or speaking French, I'd pick the dumbest reason for an attack, e.g., "A 'q' should always be followed by a 'u'. I don't make the rules, Iraq, but I will enforce them." The more irrational you look, the more scared the country will be that you will really hit them hard. I'd then give the country the old one-week notice until bombing starts. Then, after just twenty-four hours, I'd start bombing. When the stupid dictator calls to complain, I'd say, "I meant one week max. Oh, and by the way, ground troops - one week." I'm sure that would be enough to capitulate the average evildoer, but some extra measures could help intimidate others as well. Like, instead of just saturation bombing a city, super-saturation bomb it. After annihilating everything until nothing but ash is left, I'd nuke the ashes. It's that extra bit of extremely disproportionate use of force that makes other countries start to wonder if America "has it all together" and really worrying who we'll lash out against next.

Of course, Europe will start complaining, and Europe's bad mouthing of America gives comfort to our enemies. I mean, those guys values are so messed up they think calling someone a "cowboy" is an insult. Best idea would be to assassinate the leader of the first European country we hear a peep out of. This will probably make us look evil, though, when we want the image of crazy and violent. So, when the Europeans ask why, I'd claim to never have heard of the person: "I didn't even know France had a leader. Sure it wasn't suicide? Yeah, committing suicide with a sniper rifle would be hard, but not impossible if you had a five-hundred yard length of string to work the trigger." Assassination does seem a little extreme, but we're talking about Europe. I mean, what are they going to do other than quickly capitulate under a mild threat of force. We'll probably start seeing, "We all love America!" parades in bids to not be our next targets.

Now the world will be pretty convinced that America is frick'n nuts and just looking for a fight, but we need to really ingrain it into everyone's conscious so that no one will ever even contemplate crossing us. This requires making good use of our nukes. I know, nukes can kill millions of people, but they sure aren't doing anyone any good just sitting around. I mean, how many years has it been since we last dropped a bomb on someone? No one even thinks we'll actually use one now. Of course, using nukes shouldn't be done haphazardly; all uses have to be well planned out because the explosions are so cool looking that we'll want to give the press plenty of notice so they can get pictures of the mushroom cloud from all sorts of different angles. But what to nuke? Well, usually the idea is populated cities, but, by the beliefs of my morally superior religion, killing is wrong. So why can't we be more creative than nuking people. My idea is to nuke the moon; just say we thought we saw moon pe

This is Awesome

[areReady]

Somehow, this mission strikes me as one of the coolest things NASA's done in a while. It's a struggling unit of the organization, working with spare parts from scrapped projects, jury-rigging a satellite together that will tow the spent upper stage of a rocket to the moon and smash the chunk of metal otherwise slated to be space debris into the closest heavenly body to send an Earth-visible (with a decent telescope) plume from one of its poles. Finally, it will analyze the plume to figure out if there's ice there.

Seeing LCROSS 1st hand

[LanceLungstrong]

Haha funny thing is I saw the LCROSS sat just yesterday and got the complete run down of its mission from on of the lead engineers over at Northrop Grumman Space Tech in Redondo Beach.
It's actually a 2 part system. (Which is expected to be launched in March, but will crash into the moon some time in July, hopefully the 4th according to my source.)
It targets the crater and then detaches one of its rockets that which carries a camera and spectrometer on it. It gets about 4 minutes behind the impacter and then watches the impacter hit and takes data from the cloud, but the cool thing is that it eventually flies into the debris and samples it directly peering from the inside out.
All in all its going to be a terrific mission if it works but after talking to the guys that have been building this thing, they have done everything they could to make this successful.

NASA will be gone in about ten years.

[Simonetta]

With each story about the new age of space exploration that appears on Slashdot, I get this underlying feeling that there is a sharp disconnect from reality at work. Reality is that we are on the edge of a massive change in energy use. A massive decrease in energy use. And space exploration will be one of the first government programs to be cut as a result.

    It's not that space exploration by itself consumes a large amount of energy; it's that the vast network of support systems that space programs depend on will be starved for energy. Energy as in oil. Oil that is becoming expensive and will continue to get more so (and not in a linear fashion as we have been seeing). If the oil becomes difficult to get out of the ground, everything becomes massively expensive. Priorities will have to be set:cruel decisions will have to be made. And the space program will be the first to go. When food prices triple ,gasoline is rationed, stock prices tank, and house prices fall by half, people have to make choices on what they must buy with the money that they have. Space exploration is the lowest priority.

    Space exploration only appears to be an essential component of the progress of mankind when there is plenty of food, peace, and an economy growing 3-6% a year. When these conditions disappear, so does the appeal of space travel.

    Given this reality, NASA should concentrate only on projects that can be completed with useful results within a short time frame. Certainly no more than five to ten years total. That means no more fantasies about moon bases and Mars manned missions. If NASA commits itself to these hugely expensive but largely symbolic projects, they will most likely find themselves cut off from funding in the middle of the 20-30 year projects. With no lasting results to show for the expense.

    Like the Soviet space program when the USSR collapsed. If the USA didn't bail them out with heavy subsidies, the Russian space program would be nothing more than an embarrassing memory now.

    When the consequences of global warming, oil depletion, and overpopulation become fully manifest in the next ten to twenty years, NASA funding will disappear faster than the Hummer in the era of $5/gallon gasoline.

You're still too ambitious - if what you're saying is true, NASA should only concentrate on projects that can be completed in 5-10 days total. I propose a mission to the dry cleaner and back. On foot (since gasoline will be gone). With guns (to fight off the cannibals).

Kind of like what we did with all that oil, right - find it and use it all up like spoiled children with candy? It was 500 million years of energy, collected and compressed by biology, burned up in about 200 years, and in the process significantly altering the systems that made the biology possible.

I hate to break the really bad news, but we're all alone out here in a cold, dark and most unfriendly-to-life corner of the Universe. Getting to Mars is just a step - the REAL prize is making it possible for humans to journey outside our solar system, to other life sustaining places. This is a 20 thousand year project. Without that, humans remain a just a radio footnote in this dark corner. If humans take the same long-term approach to resource discovery and utilization with the rest of the planets and moons in the Solar System that we have with Earth, we will surely fail.

Toby: They think if they crash into it hard enough they can get to the center?

Sam: Yes.

Funny, but about 100 years off the mark:
http://en.wikipedia.org/wiki/Celsius

Fahrenheit was not simply some clumsy predecessor of Celsius. He was a contemporary. Fahrenheit's original scale was actually binary (arguably better than Celsius' decimal) until others decided that having the human body temperature at 96 degress wasn't as useful as having 180 degrees between melting and boiling and recalibrated the scale slightly.

Well ya know ...

What is NASA thinking!?

How soon we forget the lessons from 2002's prescient "The Time Machine". Remember what happened to the jerks who tried to blast out the moon to build luxury condos?... For all of you out there who think this is a great idea: don't come crying to me when the only public technology left is a sheet of glass with a talking hologram of Orlando Jones.

Sure, that's it... we'll bite

A few weeks ago we got first word of NASA's plan...blahblah.."

Sure, water, right. Look, if the last sixty years has taught us anything, it's that, obviously, the US must have found some labor organizers and such, with no air defenses and a society, or so-called 'sovereign nation', that is too impoverished to defend themselves.
