Re:Sell the images to raise funding money.The night sky is difficult from a photography point of view; stars are terribly faint objects and are hard to image, especially since if you take a long exposure you get streaks instead of points. The Martian moons are tiny and unimpressive compared to Earth's moon, which is larger than most dwarf planets.
However, this Martian sunset makes a very nice wallpaper.

Re:Broke up from flying 'too fast'?
If those coordinates are accurate that would mean the Air Comet flight was about 1400 miles away. If it was that bright shouldn't it also have been reported by closer observers?
You're in the middle of the Atlantic with big tropical storms about. What closer observers were you expecting? People on the ground in boats are going to be doing their best to stay inside (and afloat) and won't have a clear view of the sky. Who knows just how many flights there were nearby at the time where the pilots were looking in the right direction (forget the passengers; on an overnight flight they keep the blinds down), but it's not like the US/EU routes; there's just not that many planes going that way by comparison.
What would be interesting is if the flight was downed by a sprite. If they were flying over a big thunderstorm, that's altogether possible...

Re:To the report itself...
1. He claims that tempratures have been trending downwards for the past 11yrs - this can be debunked by a simple google search [google.com.au] and is laughable to anyone who has looked at the temprate records.
Did that, am I missing something? It looks like he is right - NASA's data shows a pretty clear leveling off after 2000. Now I do see headlines trumpeting '2008 was the 7-10th warmest year on record', but seeing as how that totally disregards any rate of change or relative comparison to the previous 5 years, it is an intellectually dishonest claim at best. But I'm no climate scientist either, so maybe I'm looking at it wrong.
My biggest issue is, and maybe you can clear this up for me, what is the level of certainty that higher CO2 levels cause higher global temperatures? Now I know CO2 is a greenhouse gas in laboratory experiments, atmospheric CO2 levels have been increasing exponentially, and global temperatures have been increasing over the past 100+ years, but I don't understand how one can claim, with a relatively high level of confidence that the three are related. I can definitely see the good hypothesis there, but I just don't see anything truly supporting the hypothesis, at least not to the 'sure thing' degree many seem to claim. Furthermore, say if the Earth is on a cooling trend over the past decade even though CO2 levels are at ever increasing record highs, wouldn't that bring the hypothesis into question? Not saying it turns it on its head by any means, but I'd think it would, as part of good process, beg for additional consideration. But again, I'm no climate scientist so maybe I'm missing something.
I guess I just don't buy the 'it's a shut case' when we're talking about such an incredibly complex system - such claims raise my bullshit meter and make me question what is being discussed. Given that thought, it seems a bit dubious that the US House would, uncharacteristically, pull legislation out of committee to rush it through a vote - especially when the bill could actually pass. -
Re:News Flash! Civil Servants Corrupt! News @ 11:0
Of course he said they were liars. They are. Prime example: Carlin claims in this "report": "There may be in the future. But global temperatures are roughly where they were in the mid-20th century. They're not going up, and if anything they're going down."

Re:The sole purpose of government is politics.
Yeah, it wasn't the Government that created the internet... oh wait, yes it was. If you can point to this great internet analogue that was squashed by the government, you might have SOME kind of credibility, otherwise it's yet more empty rhetoric. And never mind the transistor, mosfets, LSI, fiber optics, and cell phone technology invented by Bell labs with a majority of funding from the Government (what today's neocons would call 'pork'). The NIH (the major funding organization behind Bell Labs) is responsible for much of the medical breakthroughs in the last 60 years as well. And of course we don't need the CDC (heavy sarcasm). Oh, and of course I'd trust my family's clean drinking water and disease and chemical free food to the corporate sector as well, because you know they police themselves so well, as evidenced by Enron, Global Crossing, Haliburton, Qwest, Tyco, World Com, Bear-Sterns, Citigroup, etc., etc, ad infinitum, ad nauseam.
And on Bush vs Obama on the subject of 'squashing dissent':
Bush:
1. Omitted DATA for 1000 years and mandated the insertion of qualifying words such as "potentially" and "may" that the result would have been to insert "uncertainty... where there is essentially none."
2. Demanded that data from a discredited study funded in part by the American Petroleum Institute be included in climate change reports.
3. Demanded that The elimination of the summary statementâ" noncontroversial within the science community that studies climate change-that "climate change has global consequences for human health and the environment."On the other hand:
Obama:
1. Despite the fact that Alan Carlin was no part of any group tasked with studying climate control, Obama allowed his unsolicited and unwarranted report to be analyzed and subjected to PEER REVIEW, and was subsequently REJECTED by his PEERS.Yeah, that's the same exact thing.
The thing that should stand out to anyone is that Carlin claims in this "report": "There may be in the future. But global temperatures are roughly where they were in the mid-20th century. They're not going up, and if anything they're going down."
This is complete and utter HORSESHIT.

Re:News Flash! Civil Servants Corrupt! News @ 11:0
Agreed, as long as they do agree that determining costs should not fuzzy the actual root cause. Find root cause first and then determine possible actions taking costs into account.
The man states they aren't taking into account the global temperatures for the last 10 (11?) years. Any sensible person would tell you that 10 years doesn't even register on an earthly historical scale.
Of course even this scale is infinitesimal in the larger scale but we don't have solid data. That doesn't mean we can discount what we do have.
http://data.giss.nasa.gov/gistemp/2008/
The trends are pretty clear. There are all sorts of small 'drops' in global temperature over 5-10 years, yet the actual trend is to spike sharply upwards, especially in the last 20-30 years. I'm not a scientist, but even I can see a trend here. You'd have to be blind to miss it. -
Re:Safety?
There is a process called "man-rating" which means that you certify a particular launch vehicle to be able to carry a capsule containing people. The process is sort of like ISO9000 or whatever.
Aerospace engineer Rand Simberg's post on man-rating is worth a read. I don't think man-rating is what you (or most people) think it is.
Bottom line: you might have to replace or redesign parts of the rocket in order to make it man-rated. And what I was told is that it might actually be more expensive to man-rate a Delta IV heavy, than to simply design a man-rated rocket like Ares from the ground up.
The Ares I currently has a projected cost of $35 billion (and rising). There's absolutely no way it would cost that much to reliably transport humans on a Delta IV. On top of that, the Ares I has needed exemptions on many of the safety requirements which it wasn't able to meet.
According to this presentation made to the Augustine commission, building a new pad and upgrading the Delta IV Heavy to transport Orion would cost around $1.3 billion total with recurring costs of $300 million a launch. Transporting a manned capsule on a Atlas V or SpaceX Falcon 9 would have a fixed cost of around half a billion with recurring costs ~$130 million.
With numbers like that, there's absolutely no reason to go with the Ares I, especially considering how many safety concerns it has. Heck, you could fund -all- of the alternatives, launch several unmanned payloads, and pay for manned trips on whichever one performs most reliably, and it would -still- cost an order of magnitude less than the Ares I. If there's worries that the other launch vehicles might experience cost inflation, just use a fixed-price contract with milestone-based payments, like has been done with COTS.

Re:The biggest tax in US history
Same "debate", different forum.
- Don't confuse the scientists and the advocates (yes, the Venn diagram does overlap). Some advocates make insane claims. I stick with the science. Starting with the 1896 paper "On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground", by Svante Arrhenius.
- The 1934 issue was for the US, not global data. The U.S. makes up what pct. of global land area (hint: it's much less than 100%). Sloppy on your part.
- No one argues that mankind is solely responsible for climate variability. That's the lamest strawman around, and represents either dishonest or incompetent thinking. The argument that is made is that human impact is now as large, and will become larger than, modern sources of climatic variability. Re: recent trends, see the flippin' original link- we're in a solar minimum, for starters. You keep talking about cooling. Where's your data?
- You play the "I'm a victim" card exquisitely. Honest debates on science and policy are welcome. Ad naseum repetition of debunked data points, without even the pretense of providing supporting data, is annoying.

Re:Original Source and Large Images
Thanks for the link some of those pictures are amazing. Being a UKian I was quite interested in the picture of London at night (shame it's a little blurred). I downloaded the largest version of the image though (about 1.9mb) and noticed something strange. There are a surprisingly large number of green dots and a few blue dots. What I'm wondering is: are the green dots traffic lights and the blue emergency services?
I could maybe believe that the blue lights are emergency vehicles since they will typically have an uninterrupted path to the camera but traffic lights almost always have a cover which I would have thought would make them hard to spot from above. Perhaps they are just artefacts of low light photography. I'd be interested to know though.

Re:Hmmm...
Leave it in gaseous form and...
Oxygen can be produced by passing CO2 through a zirconia electrolysis cell at 800 to 1000deg C. Twenty to thirty percent of the CO2 dissociates into oxygen and carbon monoxide. Separation is accomplished by electrochemical transport of oxide ion through a membrane. A prototype reactor using this chemistry has been run for over 1000 hours. Using such a scheme, we could bring a small unit to the surface of Mars which would then continuously make oxygen for life support, propellant use, or further processing. The only additional item we would need to supply is the power to run it: a 12kW unit would produce about one metric ton of oxygen per month.
This oxygen can be converted into water if we also bring a small supply of hydrogen. Since the molecular weight of hydrogen is 2 and the molecular weight of water is 18, we can leverage 2 kilograms of hydrogen into 18 kilograms of water. The mass savings would, at some manufacturing rate, pay back the mass of the oxygen production unit. After that, we would get water for only the price of getting the hydrogen to Mars.
2CO2 --> 2CO + O2
zirconia electrolysisO2 + 2 H2 --> 2 H2O
combustion of hydrogenIf we choose to import hydrogen, there are other things we can do with it in addition to making water. A chemical reaction which converts CO2 into methane (CH4) was discovered in 1899. This is known as the Sabatier reaction. Along with the CO2, hydrogen is passed over a finely divided metal catalyst at an elevated temperature. Methane and water vapor are produced. By taking this water vapor and splitting it to obtain oxygen and hydrogen (which is recycled), we can completely convert the imported material into 4 times its mass of fuel. We also get the oxygen we need to burn this fuel in a rocket engine, fuel cell, or internal combustion engine. When combined with the production of additional oxygen via the zirconia process described above, only 4 kilograms of hydrogen can be converted into 72 kilograms of a rocket propellant mixture.

NASA presentation ignored committee's objectives
For those unfamiliar, the White House panel (the "Augustine Commission" on human spaceflight plans) was given the following objectives in their charter:
The Committee shall conduct an independent review of ongoing U.S. human space flight plans and programs, as well as alternatives, to ensure the Nation is pursuing the best trajectory for the future of human space flight â" one that is safe, innovative, affordable, and sustainable. The Committee should aim to identify and characterize a range of options that spans the reasonable possibilities for continuation of U.S. human space flight activities beyond retirement of the Space Shuttle. The identification and characterization of these options should address the following objectives:
a) expediting a new U.S. capability to support utilization of the International Space Station (ISS);
b) supporting missions to the Moon and other destinations beyond low-Earth orbit (LEO);
c) stimulating commercial space flight capability; and
d) fitting within the current budget profile for NASA exploration activities.
Unfortunately, as the "Restore the Vision" blog notes, while the presentations by SpaceX and ULA (maker of the EELVs) addressed these issues, NASA's Constellation presentation largely ignoring these objectives:
http://restorethevision.blogspot.com/2009/06/thoughts-on-june-17-human-space-flight.html
On "expediting a new U.S. capability to support utilization of the International Space Station (ISS)", the Constellation presentation was silent. It mentioned having ISS crew transport by 2015, the current goal, and how they'd made changes to improve confidence they'd meet that date (eg: reducing initial crew size to 4 on ISS missions). However, "expedite" doesn't mean "increase confidence you'll make the current late date". It means "accelerate the process or progress of : speed up". The presentation doesn't suggest any ways to have Ares/Orion ready for ISS transport by, say, 2013, nor does it suggest any ways to have any other U.S. system ready by that time.
Even former NASA Administrator Griffin always claimed that Ares/Orion was only meant as a backup for ISS support, and commercial transportation services were the intended route. Thus the natural inclination should be for NASA management to encourage commercial services to take on that role. The Constellation presentation could have suggested a COTS-D or similar competition for human transportation services, or some other means to get commercial vendors working on basic ISS transportation. Then Constellation could concentrate on the Moon and Beyond. Alternately, the presentation could have suggested ways to alter Ares/Orion to be ready by 2013. It did neither.
On "stimulating commercial space flight capability", again the Constellation presentation was silent. It has a line about "promoting international and commercial participation in exploration", but no details on what that participation is. Where is this participation in the plan? The original goal of the Vision for Space Exploration was for launch support to be done commercially, except perhaps for heavy lift, if needed. Where is that in the plan? The presentation didn't suggest that any of the components of the Constellation architecture be implemented commercially. There's a picture on "Future Exploration Capabilities" with an Ares V linked to some "Commercial and Civil LEO" spacecraft, but what commercial activity is going to be launched by Ares V? There's a slide on "Economic Impact: Contractor" and others on billions of dollars of prime contract value (as if high cost is a virtue), but that's not commercial, it's government contracts. If a contractor is going to sell commercial services enabled by its government contracts, I'm willing to call that commercial, but how much of

Re:it is not the "largest evel launched into space
Why do they make Hubble and Herschel sensitive to infrared light? I would think it most important to pick a spectrum that will provide the best information...
Exactly. What spectrum you pick depends on what information you want to get.
Infrared is good for a lot of things. Dust clouds are mostly transparent to infrared, for example, so the infrared is good if you want to look, say, at the nuclei of galaxies (such as our own galaxy) which are surrounded by dust. And if you want to look at galaxies at high redshifts, which is to say, far away (and hence far back in time), infrared is good because the light is shifted into the infrared. Infrared is good at looking for planets, since they emit in the thermal infrared. And many other things.
But if you want to look at gamma-ray bursts from supernovae, no, probably infrared isn't the right way to look. You might want to try the Fermi telescope instead.

Of course because southern CA also gets water from the Colorado River when water prices rise in AZ they will in Southern CA too.

Re:Cars

Documented as brighter than the full Moon, the spectacular fireball crossed parts of several US states during its 40 seconds of glory before landing in Peekskill, New York. The resulting meteorite, pictured here, is composed of dense rock and has the size and mass of an extremely heavy bowling ball. If you are lucky enough to find a meteorite just after impact, do not pick it up -- parts of it are likely to be either very hot or very cold. In tonight's possibly spectacular Leonid meteor shower, few meteors, if any, are expected to hit the ground. "

As aircraft fly at >30000 feet, the number of meteorites will be greater than the number that hit the ground. Atmospheric density is many times greater at sea level than at 30k+ feet, so more will penetrate the atmosphere to that height. It would only take a small rock, travelling at the speeds meteors do, to severely compromise a wing or even the cabin.
