Finally Explains Sounds of the Northern Lights!Being a Canuck that has lived north of 60 I have seen incredible instances of the Northern Lights. What I always thought was strange was when the lights were in certain patterns and intensities I heard a strange crackling like static electric charges. Knowing that the lights originated from well beyond the atmosphere I just dismissed this as a fantasy. UNTIL one day having a beer in a pub in Watson Lake Yukon I overheard several people claiming to hear the lights the same way as I do!
THIS article finally confirms my suspicion that it is a normal response within some individuals to easily perceive light in an auditory fashion. Perhaps this is why mood lighting is so effective and disco balls were such a hit though they are essentially useless.
All though this explanation from some scientists defies this logic, I have been with other people in the pitch dark watching the lights at the same time and they did not hear the sounds I was experiencing and the sound was not at all as described in the article on Space. The sounds that happen to me are definitely like an electrical spark crackling not at all like applause!

about the nice LADEE!
hello nice LADEE! http://www.space.com/22639-moon-dust-mystery-nasa-spacecraft.html
The Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft is expected to investigate lunar dust and the moon's extremely thin atmosphere once the craft makes it into orbit around Earth's closest celestial neighbor about 30 days after launch.
that's right, the moon has an atmosphere kinda. it's technically an exosphere.
In the moon's atmosphere, there are only 100 molecules per cubic centimeter. In comparison, Earth's atmosphere at sea level has about 100 billion billion molecules per cubic centimeter. The total mass of these gases is about 55,000 pounds (25,000 kilograms), about the same weight as a loaded dump truck.
before you ask, neither LADEE nor the internet is a big truck.
what they aren't telling you is that the NSA is coercing NASA to ***CARRIER LOST***

Re:You have to wonder how much that atmosphere...
Even though there's a thin atmosphere on the Moon it is constantly hammered by Solar Heating and the Solar Winds. It's really an exosphere rather than an atmosphere. I doubt any dust raised by impacts would last there very long at all but also remember that it's constantly pelted by all kinds of cosmic detritus hence all the craters so it would be difficult to discern if any debris co-mingling with the gases was man-made or a natural occurrence.

Re:They're far from simple

8 Meter Space Telescope
Astronomers were proposing to use Ares V to launch an 8 meter reflector into space. 1.5 meters larger than Megellan; 35% more collecting area and far above the atmosphere. That mirror would have been able to detect biosignatures on extrasolar planets.
Then Obama cancelled it, so you probably won't live to see such a thing.

Re:58 Second Burn?
To give a practical perspective on meteor sizes, recall that the Chelyabinsk meteor which arrived at Russia this same year had around 15-20 m of diameter
http://en.wikipedia.org/wiki/Chelyabinsk_meteor
And the space rock that carved Meteor Crater (or Barringer crater) in Arizona, around 50 K years ago, had about 40 meters of diameter.
http://www.space.com/834-mystery-arizona-meteor-crater-solved.html
So, a 60 meters meteor will probably create a big, big, hole (depending on the velocity at arrival and landing angle) if it falls to Earth. I also remember reading that the impact in Arizona caused much devastation in the surrounding areas, up to several tens of miles from the crater.
Finally, the meteor that "created" the gulf of Mexico and "killed" most of the dinosaurs, about 66 million years ago, had probably around 10 km of diameter.

Re:who pays for maintenance?
Define "meaningful".
The beauty of the Star Trek universe is that people have the capability to define themselves what is meaningful to them and pursue it without having to worry about if they will be able to afford to feed, clothe, and house themselves. For some people, that might be nothing but seeing how many other people they can fuck. I believe for a lot more people, that meaning will come from creative or scientific endeavors.
I'm sorry, but you have some sort of noble-savage view of human beings, or a view that supposes the existence of a soul (i.e a view based on philosophy or religion).
LOL. There aren't enough LOLs in the world for this sentence.
If there really was such a thing as "post-scarcity", or if it were even physically possible, we would still be just another species of animal. We would still be nothing more than biological organisms following our perceived self interest.
Nanotechnology research aims at this very goal with our very biology as proof of concept showing that atomically precise manufacturing is possible, and I believe it's just a matter of when, not if. So we're animals. So what? You think that we're constrained by biology to have no other interests than eating and fucking?
The number of people who would risk their lives for some "meaningful" reason - when there was no material one - in deep space for no material benefit would be in the fraction of single digits.
These people would probably disagree. Thankfully, not everyone has the same outlook on life as you do.

Re:But there's nothing to listen to in Africa
Nobody cares enough about Africa to listen in on them. The only thing Africa has is resources, and China already is buying them. Is the infrastructure subject to surveillance? Sure, but every infrastructure is, even heterogeneous ones like the US.
So, nothing to see in Africa? Just move along? I don't think so.
Just like Europe, South America, and Asia, Africa is an entire continent of nations, some of which have drawn considerable attention in the last couple of years. I assume you've heard of Libya? Egypt? Algeria? South Africa? There is a lot going on in Africa, and the Chinese are heavily involved. There are plenty of things they might want to listen to.

China To Establish A Naval Base Around Somalia
As the threat of piracy continues. And as Somali pirates continue with their awkward trade to kidnap foreign ships, a Chinese Admiral has revealed China’s proposal to establish a naval base in the region in its commitment to thwart piracy and finally end this tragedy in the gulf of Eden. The lazy pirates who have no intentions to pursue an education or employment see piracy as an easy way to make money. About 75% of piracy in the region is being masterminded by terror groups to finance their illegal activities.
Rear Admiral Yin Zhou’s, a senior Chinese naval officer has suggested that China will establish a permanent base in the Gulf of Aden to aid its anti-piracy operations. The proposal was posted on China’s Defence ministry website. The Admiral went on to say that supplying and maintaining the fleet off Somalia was challenging without such a base, and said other nations were unlikely to object. The Chinese navy curr

What's going on with Boeing?
Boeing has had other recent problems in quality and reliability, with some recent Boeing-managed programs being cancelled, because they were going so badly.
In 2005, FIA (run by Boeing) was canceled. The New York Times called it "perhaps the most spectacular and expensive failure in the 50-year history of American spy satellite projects.
... A torrent of defective parts, like gyroscopes and electric cables, repeatedly stalled work. Even an elementary rule of spacecraft construction — never use tin because it deforms in space and can short-circuit electronic components — was violated by parts suppliers. By the time the project, known by its initials, F.I.A., was killed in September 2005 — a year after the first satellite was originally to have been delivered — cost estimates ran as high as $18 billion."From space.com, "But Boeing quickly ran into troubles on the highly ambitious and complex FIA program, which fell years behind schedule and overran its budget by billions of dollars. In 2005, having concluded that Boeing’s problems were intractable, the Office of the Director of National Intelligence directed the NRO to terminate the optical portion of the contract."
In 2011, the Boeing-run SBI Net program was canceled, because it was going so badly. From stltoday.com, "It was originally envisioned to stretch the 1,969-mile border between the U.S. and Mexico but initial phases of the $1 billion project took longer than anticipated to complete and covered just a small portion, 53 miles, since the project began."
In 2011, the "Joint Tactical Radio System’s Ground Mobile Radios (GMR)" project, run by Boeing, was canceled. From a Bloomberg article: "Based on growth in the unit procurement costs, I am terminating the program," Frank Kendall wrote in a letter to Congress. "... The GMR program last year was estimated to cost $19.5 billion."
And a USA Today article tells about other recent problems with Boeing. For example, "V-22 Osprey. The tilt-rotor aircraft, made in partnership with Bell Helicopter, is under congressional scrutiny because of concerns about its high cost of operation, reliability and safety". And "Joint Tactical Radio System Cluster 1. Boeing's management of the project for the military was so bad it received a stop-work order from the Defense Department. Eventually, the program was restructured rather than canceled but with Boeing in a diminished role."

big whoop
it's great that US mil think they are hot shit with unmanned drones but the japanese beat them a year ago in a big way. The stakes are waaay higher in space. Worst case for a drone crash on a carrier is billions in damage. Worst case in space is taking down our only space station that took over a decade and 100 billion dollars to build and turn the station into a massive hazard for all future space missions.

Re:War!
If we had continued working towards colonizing the moon and Mars, our technology would have grown better to meet those goals.
The horse carriage would have never grown into the horseless carriage, and finally the modern automobile, if we all lived together on a 2 square mile island. There's no reason to drive 150mph, if it would shorten your trip to under 1 minute.
If there were regular commuter flights from Earth to Mars, you can be sure we'd have improved. Look at the difference between a Model 14 Benoist and the Concorde, Airbus A380, or Boeing 787.
The demand drives innovation. Over the last century, we redefined the demand from crossing a small body of water faster, to being able to fly around the world faster.
We want to get from Point A to Point B in something bigger, faster, and cheaper. The Concorde won on the faster, but died because it was anything but cheaper. That, unfortunately, is the fate of suborbital aircraft.
When we redefine Point A and Point B to be Earth to another planet, we'll find better ways to do it. When that is extended out to other stars, our technology will grow even more.
As you said, our space technology isn't much more than a horse in carriage. Without a goal and a reason to do it, it will never become a reality. We're all one planetary ELE away from being the last of our species. We didn't even know about the meteor that hit Russia, until it came down, damaging 7,200 buildings, and injuring almost 1,500 people. They're considered too small... Imagine the damage from a few of these, if they made impact on more populated areas.

Re:So.
We will never travel faster than the speed of light. That, however, does not mean we can not reach distant star systems. It will simply be a very, very, long trip.
That depends. There are theories that show that "warp travel" of varying definitions may be possible. I recall one in which maintaining a stable "warp bubble" for what is effectively faster than light travel was feasible. The problem is getting into the bubble itself, which required enormous energy - far more than maintaining it or traveling in it. There are other theories and studies under way. And given that there is still a lot of physics we don't understand (dark energy, dark matter, unification of quantum mechanics and relativity), it may be the answer is out there. The article below discusses one such idea that may be unrelated to the one I mentioned.

Re:Antimatter

Here's the list
Because the summary couldn't be bothered.
Five are military (four are Navy test pilots, surprising no one, the fifth is a doctor), and the other three are useful Ph.D.s. Cassada really is the only standout among them, because he's a physicist, not a CTO, by training (which will make the scientific community at least a little happier about manned space missions). Meir is an enigma for sure, but makes sense from a strategic standpoint: she's done some time for NASA at JSC and Lockheed Martin doing human experiments and working with astronauts on the ISS, is interested in astrobiology, and worked at Aquarius Underwater Laboratory, which was later used to simulate an asteroid mission last year.
All of them are mostly in their mid to late 30s, which means the next class of astronauts are likely to be Millenials: all you shiny new Ph.D.s should start polishing your resumes for space!

Re:What happened to it?
The lack of a magnetic field might indeed be the explanation, but right now the case for it is not very strong. At least with the current solar activity, the observed atmospheric mass loss rates from Earth, Venus and Mars are comparable, even though only Earth has a significant magnetic field. There is a good article about these issues here
-
Re:What happened to it?
I recall this being due to an ancient impact that blasted away most the atmosphere, etc. I was watching some show (perhaps The Universe) that explained that there in fact lies a huge impact crater on most of the face of Mars that coincides with this theory. Just a quick Google gave me this link -- though I got my information from the aforementioned tv show and not the link.

Re:Okay
Best source I can find is this article, which lists the surface radiation as around
.7 millisieverts a day, or around the same as low Earth Orbit (Mars atmosphere is extremely thin, so it doesn't give as much protection as Earth's does from cosmic rays). This is vastly more than people are exposed to on Earth, and could definitely pose long-term health risks for a colony or other one-way mission. -
Re:more antimatter near Earth than expected
If someone figures out how to capture and store antimatter on long timescales (even just positronium), this could be an orbital energy source. It's known that lightning creates antimatter and ejects it into space.
Once a method to capture and store antimatter from lightning has been created, this could be used for a low orbit fuel station. Just because there's a tiny amount detected doesn't mean that a much larger quantity isn't created by thunderstorms and lost to space and/or annihilation events from collisions with matter.
After a design is known to work, a station could be placed in orbit over Jupiter's great red spot for continuous collection.

Re:Total bullshit
If the IAU can't get off their collective asses and start doing their job properly, then they'll soon find themselves outvoted by the likes of Uwingu who are going to do it for them. The IAU only has the position it has because they did a good job of gaining consensus until recently with the whole Pluto fiasco. And if you don't think that was a fiasco, then you don't know enough about it. If they screw up exoplanet naming, then people are going to start looking to someone else or just ignore the IAU. Nobody wants that, so perhaps the IAU should stop acting like entitled pricks and do their damn job.

Re:FUD summary as usual
Lightning also creates small quantities of natural antimatter that gets ejected to space. If only containment lasted longer than 16 minutes, orbital refueling stations around planets with dense atmospheres could become a real possibility (i.e. every local planet except Mercury and Mars).

Re:Nice work ...
That "crispy" look is just soot/ash from the heat shield. You can see several places below the channel for the drogue chute's cord (the diagonal groove) where it has been rubbed off, showing a pristine white underneath. Besides, that picture only shows the bad side of the capsule. Take a look at the capsule from a few different angles. You see, contrary to popular belief, capsules like this do not traverse through the atmosphere straight on. They "fly" in a tilted orientation. That's why the soot marks are on an angle, and one side of the capsule looks charred, while the other looks barely singed.

"Huge"??
That meteorite was only 15 to 17 meters long.

Re:Almost?
As fast as that thing was moving I don't think you'd have a chance of hitting it with a missile. I mean the whole video was only 49 seconds long. Even with the part of the meteor's path that wasn't in the video it undoubtedly lasted less than a minute. Checking Space.com it says the meteor entered the atmosphere as a speed of about 64,800 kph (40, 260 mph) and exploded over Chelyabinsk at an altitude of 15-20 km (50,000-65,000 feet). Pretty tough for a missile to catch I'd say.
