It happened again! Quad pole as one word auto corrects to dipole.

4) Night flyers can also use celestial navigation, as has been used by U2, Apollo, and SR-71 pilots.

It will if there is little to no magnetic field and a few of the GPS satellites fry.

Moving, or even reversing polarity, has no bearing on the strength of the field. Only its orientation.
There is zero evidence of elevated cosmic ray- induced cosmogenesis observed for 'ANY' magnetic excursion, or reversal over the past 150-million years.
Lack of increased cosmogenesis indicates no loss or decrease of the magnetic field flux.

It's not vBulletin. What are your browser and OS?

Quadrupole
A quadrupole or quadrapole is one of a sequence of configurations of things like electric charge or current, or gravitational mass that can exist in ideal form, but it is usually just part of a multipole expansion of a more complex structure reflecting various orders of complexity.

Depending on the duration, up to 3/4 gps satellites fry, but there are 3 constellations so you would still have accuracy to 3meters. Good enough for nukes.
Our military stuff is hardened, probably everyone elses, ditto. I expect it to out survive us.
Exactly how is that cosmogenesis measured from millennial data?

* Carbon-14 and Berylium-10 are created from cosmic particle bombardment of the upper atmosphere, and follow the 11-year solar magnetic cycle variability.
* Sampled lavas will reveal magnetic flux magnitude and lines of flux orientation at the time of freezing.
* And radioisotopic dating will provide their age.
* There are 50- dating techniques available to scientists, which include radioisotopes dating to the creation of the solar system.

news.slashdot.org/story/21/12/16/208238/wind-power-becomes-spains-leading-energy-source-for-2021

An anonymous reader shares a report:

Even if the wind stops blowing in the next three weeks, wind power will end the year as the leading source of electricity in Spain. This will mean wind overtaking nuclear in the national energy matrix for the first time since 2013, the only year since records began in which wind turbines were the main source of power. That year was particularly good in terms of wind resources while nuclear was affected by the closure of the Garoña plant in Burgos. Since then, however, wind power has continued to grow as a percentage of total energy generated both in absolute and relative terms, a trend that looks to continue in the near future. The milestone, advanced by Spanish news site Nius, is just a taste of things to come.

New Discovery on Mars!! Why SpaceX should DEFINITELY put their first colony in the Valles Marineris.

[aerohead]

PBS did a little blurb on it last night.
It's 5X deeper than the Grand Canyon, but it's there.
And also,NASA is confident that they'll find water on the Moon's poles, deep inside craters where the sunlight can't reach. Important for oxygen, water, and rocket fuel manufacture.

[freebeard]

Agreed there is water at the poles, but Valles Marineris is 'low hanging fruit' compared.

The central spot where the thunderbolt touched down is relatively flat and that makes for a good landing site, but to the SoutWest there are steep canyons and [most likely] lava tubes to offer radiation protection.

Observation is complete opposite of what you assume.
As the poles have moved over the last 160 years it's gotten weaker, its moved more in the last 20 years than the previous 120 years and also weakened more in the last 20 years than the past 120.
So what makes you think as the poles move the magnetic field won't lose strength?
The gps satellites are up about 12,000 miles, they could quite easily be outside of the earth's protective field while the atmosphere is still quite well protected.
Can you assume that things 12,000 miles up will be protected?
