A new theoretical study explores how activity high above Earth could subtly influence processes deep within the planet’s crust. Researchers at Kyoto University are advancing a new idea about how space ...

Researchers at Kyoto University have proposed a new physical model that explores how disturbances in the ionosphere may exert ...

A possible alternative to active debris removal (ADR) by laser is ablative propulsion by a remotely transmitted electron beam ...

Working in agriculture means facing a variety of challenges imposed by nature. Unfavorable weather conditions, such as irregular rainfall, strong winds and hail, are common obstacles for producers and ...

THE general increase of ionospheric critical frequencies with sunspot number is well known, but the corresponding changes in ionospheric structure are not obvious from the critical frequency data ...

NASA is embarking on the Sporadic-E ElectroDynamics (SEED) mission, launching rockets from Kwajalein Atoll to investigate unpredictable Sporadic-E layers in the ionosphere. These layers disrupt radio ...

This year’s European Navigation Conference (April 7–10 in Bordeaux, France) got underway with “Good news from up there .…” Galileo’s seventh and eighth satellites launched successfully in late March, ...

Scientists studying the ionosphere in Antarctica have discovered day-night variations in ionospheric density, regardless of the 24-hour sunlight in summer and darkness in winter. They observed a ...

The performance of radio systems used for communications, navigation and remote sensing is affected by ionospheric variability. Ionospheric disturbances caused by space weather effects can degrade the ...
