Will the Earth's Tail Fry Moon Visitors?

Roland Piquepaille writes "Researchers working for NASA's Lunar Reconnaissance Orbiter mission have discovered that the Earth's magnetic tail could be harmful to future astronauts. The moon stays inside Earth's 'magnetotail' for six days every month — during full moon. This can have consequences ranging from lunar 'dust storms' to strong electrostatic discharges, according to one researcher quoted by NASA in 'The Moon and the Magnetotail.' So far, this is pure speculation: no man has been on the moon when the magnetotail hits. As added the same scientist, 'Apollo astronauts never landed on a full moon and they never experienced the magnetotail.' But read more for additional details about how Earth's magnetotail could affect men on the moon."

All I know is, I don't get any tail for six days every month!

Not that he'll understand, he probably doesn't get any tail for the other 24 days either.

Haha! And people wonder why more women don't take an interest in computers. It's not the computers they're afraid of, it's putting up with all the comments like this... Good thing I can handle it -flex- :D

Re:All I know

[that IT girl]

Oh, of course. In fact, I'm secure and know I'm good at my job, so generally I find these comments pretty funny. Especially knowing some of the women that I work with who I just know HAD to have gotten where they are through... unscrupulous means. Nevertheless, it's not exactly a welcoming environment for the average lady, no matter how savvy. ;)

Re:All I know

[that IT girl]

But you sure can try! When I worked for the computer department in college, I had this one professor whose situation had me stumped. I had to re-install her operating system once every week or two, and even replaced the hard drive once because of bad sectors all over the place. I had no idea what was going on; she swore she just used it for emails and her worksheets, etc. After a while, she called one day, and I finally decided I'd go take a look at it in it's usual environment instead of having her bring it up like usual. And what did I see? About 20 cute but destructive little magnets all over the side of it. x.x She'd been taking them off every time she brought me her computer, so I had no idea they were on usually on there. After I explained why this was a very bad idea and advised her not to put magnets near it, her computer never had a problem again. Fancy that!

Re:All I know

And all I know is....I also don't get any tail the other 24 days. Well, you'll get more tail living on the moon than you do living in your mom's basement.

Re:All I know

The interesting thing is that, before we replaced the job with machines, computation and computer science was dominated by women. It was one of those few "acceptable careers."

Maybe it's just that I pay more attention to this area more than others, but it seems like IT in general is an unfriendly place to be. It's fairly elitist in almost every aspect. This is the same complaint of a lot of people moving to linux, women in the industry, and foreigners in the US. There's very much a "who let /you/ in here?" attitude.

Then again, it seems like the people who are genuinely exclusionary are a very small minority; as it's been stated elsewhere, the status quo is very harsh amongst itself. It makes for a stressful situation for most normal people: If I say this to be friendly, will she perceive it as inappropriate? If I say this to rib her, will she take it as hostile? If I don't say anything, will she take it as exclusion? But on the other side: Was he trying to be mean or funny? Is he an awkward person is it because I'm a woman? Is he being friendly or flirty?

We've all become so self-conscious about what is a real problem, but which has come to dominate so many professional relationships, especially towards introduction. We all need to get over it, but it's the most extreme cases (genuine bigotry or oversensitivity) that hold us all back.

Re:All I know

I find it quite amusing personally. Perhaps if you were more secure in the fact that Women can be incredible engineers and supremely intelligent people, and not just foodmakers, you'd be able to get the joke as well.

Poking fun at stereotypes is only amusing to people who aren't racist or sexist. To those who are it tends to seem offensive. I'm perfectly willing to crack disability jokes, if the person I'm talking to knows I'm kidding and won't be offended. Same goes with racist jokes (me and my friends have an ongoing joke about the token black person who appears in many movies and games which we find funny and non-offensive but I'm sure you would think is racist).

You reveal your own sexism by not being able to accept the fact that the stereotypical woman homemaker isn't the common case anymore, and that it's therefore open for jokes along with all other past stereotypes (for a good example of funny old stereotypes just watch any monty python skit/movie :P)

[somersault]

There was a Scotsman, an Englishman and an.. oh wait, you probably wouldn't get it anyway..

For the record, I think the GP sounds like he has a decent sense of humour, and you're just scared of upsetting people. Personally I think there's a lot of humour to be found in stereotypes, as long as it is the ironic kind and not just vicious racism and the like. I don't mind people making jokes about my ethnicity (Scottish), the fact that I am not a morning person, blah blah blah.

There have been people at my work who do seem genuinely bigoted and in those cases, your talk of avoiding confrontation and such is valid, but the GP doesn't sound like a bigot. And as an aside, how on earth do you think that weight is 'beyond the control' of the subject (unless they perhaps aren't physically well enough to do exercise). If you get regular exercise and don't eat junk then it's going to be pretty difficult for your body to pile on the pounds. I have a pretty good metabolism (I recognise that some people put on weight more easily than others, I'm 14 stone/196 pounds, 6'2", my sister goes crazy whenever I suggest I'm getting 'fat', because I'm not :p ), but I also am trying to keep more of a reign of my appetite these days. FFS, I hate political correctness so much..

Re:All I know

[Jarjarthejedi]

"I prefer to treat them and others the way I prefer to be treated myself: with respect."

My friends and I have a habit of showing respect through joking. I once confused a teacher by getting in a huge joke argument with one of my best friends, which had us both laughing and the teacher wondering how we could be friends and be so mean to one another.

"These conditions do not apply to everyone and you assume too much"

They apply to myself and those I consider friends. Ergo we all enjoy such jokes (especially jabs at one of my friends because he's of Dutch origin and just happens to be a very frugal person. The two are entirely unrelated (there's a good reason for his frugality) but we all have fun poking fun at it, even the friend).

If you don't like such humor then that's fine, perhaps I went a little overboard in my statements because I was in a bad mood. But don't assume that those of us who do enjoy such humor are horrible people either. We happen to enjoy poking fun at someone because of things beyond their control, because it's clearly joking. I myself am often poked fun of for my height, all in good fun because we all know and acknowledge that none of these things are going to change, could be changed, and so laughing at them isn't offensive, because the person knows it's all in good fun (and trust me, they enjoy it just as much as I do, otherwise my best friend would long ago have ditched me :P).

And no, I'm not particurally well known for this type of humor. It's only in the company of those who I know are mature enough to not be offended, and find the jokes humorous, that I tell such jokes, and even then it wasn't I who started the trend with my friends (believe it or not it was the Dutch friend, who started the trend by [i]poking fun at his own frugality[/i].

There are many different types of people out there. Some of us can enjoy a good laugh at someone else's expense (especially our own expense), so long as the joke is meant in good fun and not intended to hurt them, and when we get together the stereotypes will fly right out the window and we'll all have a great time making fun of each other, but most of all making fun of people who actually believe the racist, sexist material we use :P.

Full Moon on Moon?

[$0.02]

The moon stays inside Earth's 'magnetotail' for six days every month â" during full moon. Wouldn't that be full earth instead?

Re:Full Moon on Moon?

[frovingslosh]

No, it would be a "new Earth", which happens from the moon's viewpoint when Earth sees a full moon. A full Earth, from the moon's viewpoint, would happen two weeks later when the moon is "new" and not in the tail at all. Since a "new Earth" and a "full moon" happen at the same time, the full moon reference is perfectly correct and makes more sense.

One reply seemed to take this seriously, not as a joke, so I'll bite too.

To believe that the moon landing never happened as per Fox documentary (oxymoron?) you would have to..

.. believe that Soviet and China was in on the conspiracy, at the height of the cold war when this was a major blow to them. They could easily have disproved a fake moon landing, and choose to let US revel in glory instead..?

.. believe that all the actual moon rock available to scientists and universities is... what?

That's just two Occams Razor points, not going into NASAs rebuttals against the so called photo evidence.

Not every month

[Geoffrey.landis]

Actually, the moon doesn't pass through Earth's magnetotail every month-- the moon's orbit is inclined to the ecliptic, so some months the magnetotail passes north or south of the moon-- it depends on season and precession.

Re:Not every month

[spazdor]

Quite right. Otherwise there'd be a lunar and a solar eclipse every month.

Re:Not every month

[Anonymous Coward]

Even the most conservative estimate indicates the moon always passes through the magnetotail, because the earth's magnetotail is much larger than the earth's shadow. Here's my calculation. If I made a mistake, please correct me.

The Magnetotail is 20-25 Re(earth radii) across depending on season(minimum 10 Re in radius); much bigger than the shadow of the earth(2 Re). The moon's orbit is inclined 5% off the ecliptic(the plane of earth's orbit around the sun). The earth's magnetotail is essentially in this plane. The moon is at a distance of 405696 km at apogee (~60 Re). This means even at the point when the moon is furthest from the ecliptic plane (ie apogee is coaligned with the magnetotail) it will still fall inside the magnetotail.

60.24 * sin((5./180)*pi) = 5.25 Re < 10 Re

Thus, precession or no, the moon will always be in the magnetotail for at least part of each orbit. It would take extremely extraordinary(read: improbable) solar wind conditions to make the magnetotail thin to 5 Re.

Ahem

Just one example of what might go on that we can't see with regards to lunar dust storms. Took me all of a few seconds to find and there looks to be a lot more to read. Google is your friend.

Re:If we want to go to the moon

[arivanov]

Russian rovers have happily survived through it.

They were however idle during the night and ran on electronics which are considerably less prone to radiation problems.

Mental image:

Crowd of corpulent Southerners at a Crawfish Tail Fry somewhere on the Redneck Rivera dropping trou' to moon a luxury liner passing by.

Re:If we want to go to the moon

[arivanov]

Oops... Should have read it again before posting. The happy event happens during full moon when it is nicely lit by the sun so the rovers have indeed experienced it and none of them has observed any such wierd things. They were up there for months so I this is mostly likely not the kind of problem to worry about. It is least likely to be even close to the amount of radiation pounding a station will get during a solar storm.

moot

This is moot, as we all know they will not make it thought the Radiation Belt anyway.

Safe Space Travel

Alas, the days where one could travel to the moon in comfort and safety are behind us. Now it is nearly as hazardous as trying to merge onto 294.

Giant, predictable magnetic distrubance?

[toastee]

Sounds like a great opportunity to harness the energy potential. this could very well be useful.

how about ISS?

[Anonymous Coward]

why isn't the ISS affected by the "magnetic tail"? It has to pass trough it.

Simple Solution

[jeffkjo1]

Imagine what it feels like to be a sock pulled crackling from a dryer. Astronauts on the moon during a magnetotail crossing might be able to tell you. Walking across the dusty charged-up lunar terrain, the astronauts themselves would gather a load of excess charge. Touching another astronaut, a doorknob, a piece of sensitive electronics -- any of these simple actions could produce an unwelcome discharge.

There's a simple solution to the excessive static discharge, all NASA needs to do is get a dryer sheet the size of Michigan. Plus, it would have the added bonus of being able to be used as a giant parachute, ala pre-school... think about how high you could bounce with that thing.

MegaMan

Didn't we defeat magnetotail back in MegaMan 3 using our Plasma Buster?

Roland the Plogger again

[Animats]

It's Roland the Plogger, wrong as usual.

It's not like this is a newly discovered phenomenon. After all, there have been many unmanned moon landings and equipment has operated through the "magnetotail" many times. The USSR landed two lunar rovers, both of which worked for months. Lunokhod 1 was operational for 322 days, and Lunokhod 2 was operational for about four months. This was in the early 1970s.

Re:Roland the Plogger again

[Cecil]

This was in the early 1970s.

See, there's your problem. The magnetotail wasn't so big back then, because of the ozone hole and global warming and oprah winfrey. Also, gnomes did it.

Re:Roland the Plogger again

And Roland got his "for more information" link to his blog through again. Recently the editors have omitted these (though if you look in the firehose, Roland puts his spammy blog link in every submission).
