Earth's magnetic field is not about to flip. While the intensity of this field has weakened in the last couple hundred of years, researchers have found that this doesn't mean it's about to reverse.

 

Humans have lived through dips in magnetic field intensity before. However, there are debates about whether reversals of the magnetic field in the distant past had any connection to species extinctions. Today, a magnetic field reversal would have a huge impact due to one very important thing: technology. The magnetic field deflects the solar wind and cosmic rays. This means that with a weaker field, more radiation gets through which can disrupt power grids and satellite communications.
 
"The field may be decreasing rapidly, but we're not yet down to the long-term average," said Dennis Kent, one of the researchers, in a news release. "In 100 years, the field may even go back the other direction [in intensity]."

Earth's Magnetic Field Flip Could Happen Sooner Than Expected

Changes measured by the Swarm satellite show that our magnetic field is weakening 10 times faster than originally predicted, especially over the Western Hemisphere

Earth's magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm.

 

The biggest weak spots in the magnetic field — which extends 370,000 miles (600,000 kilometers) above the planet's surface — have sprung up over the Western Hemisphere, while the field has strengthened over areas like the southern Indian Ocean, according to the magnetometers onboard the Swarm satellites — three separate satellites floating in tandem.

The scientists who conducted the study are still unsure why the magnetic field is weakening, but one likely reason is that Earth's magnetic poles are getting ready to flip, said Rune Floberghagen, the ESA's Swarm mission manager. In fact, the data suggest magnetic north is moving toward Siberia.
"Such a flip is not instantaneous, but would take many hundred if not a few thousand years," Floberghagen told Live Science. "They have happened many times in the past."[50 Amazing Facts About Planet Earth]

SPACE WEATHER BALLOON UPDATE: 
 
by Dr. Tony Phillips.


The payload of a space weather balloon launched Jan. 8th by the students of Earth to Sky Calculus has been recovered from its landing site in Death Valley National Park. The purpose of the flight was to study a solar radiation storm in progress at the time of the launch. Analyzing the data may take a few days. Meanwhile, here is the view from the stratosphere:

These pictures were taken by a pair of Hero3+ cameras looking out of the payload capsule. The upper frame shows the Sierra Nevada mountain range, unusually brown for this time of year as California endures a historic drought. The lower frame captures the balloon popping at an altitude of approximately 100,000 feet. Click on each frame for a closer look. The landscape shot was made using the Hero3+'s new "superview mode"--a favorite of snowboarders and now, for the first time, balloonists!

In addition to cameras, the payload contained an x-ray/gamma-ray dosimeter, a GPS altimeter, and a cryogenic thermometer. Together these instruments can form a complete thermal and radiation profile of the atmosphere throughout the flight. The students plan to pay special attention to data collected at aviation altitudes to learn how much radiation air travelers absorb during periods of high solar activity.
