The National Aeronautics and Space Administration is set to carry out three missions to investigate the so-called northern polar cusp, which may possibly give a clue towards explaining the strange phenomenon making gadgets act up there.
This is not the only mystery of the funnels at the North and South Poles, through which winds from the Sun enter our planet’s atmosphere – other regions are shielded by our planet’s magnetic field. The northern polar cusp also has a patch of dense atmosphere. This, according to Mark Conde, the principal investigator on one of these missions – Cusp Region Experiment-2 (CREX-2), is associated with a pressure change that would “cause a continuous hurricane stronger than anything seen in meteorological records" if it occurred at ground level. This blob could be hampering the work of special spacecraft and satellites, impacting GPS and other signals because of the severe turbulence.
As Science Alert reports, it is hoped that these missions will provide a better look at these enigmatic irregularities, which can result in disruptions of communication systems, and to predict its behaviour in the future.
"Turbulence is one of the really hard remaining questions in classical physics. We don't really know what it is because we have no direct measurements yet”, said Norwegian space physicist Jøran Moen, who leads Cusp Irregularities-5, intended to measure turbulence and distinguish it from electric waves.
Apart from these three missions, there are six more ventures tasked with finding out more about the northern polar cusp – some of these have already been carried out.
"Each mission has its own strengths", the head of CHI, physicist Miguel Larsen, told the outlet.
