Its major goals are to characterise the subsurface layers of sediments and possibly detect underground water or ice, to conduct large-scale altimetry mapping and provide data on the planet's ionosphere .
A major role of the atmosphere was to filter out the ionising radiation from the sun by ionising the high atmosphere and forming the ionosphere .
Third, Titan is unique among moons in the Solar System for its thick atmosphere, which is complete with an ionosphere - an outer layer of ionized atoms that readily interact with magnetic fields.
In 1931 he gave the Royal Society Bakerian lecture which was a classic in which he developed the now standard layer theory for the lower ionosphere .
In addition, MARSIS will conduct large-scale altimetry mapping and provide data on the planet's ionosphere , as this electrically charged region of the upper atmosphere reflects radio waves too.
There's always sand in the cogs somewhere, even if these days its the ionosphere , or the troposphere, where things get gritty.
This results in a powerful electric field between the cloud tops and the ionosphere , the outer layer of Earth's atmosphere.
The ionosphere is the layer extending from about 80 km to the outer reaches of the atmosphere that includes charged particles.
The Columbia's port side plasma cannons, which had been quiet through most of the engagement, opened up against the two alien vessels heading for the planet's ionosphere .
The flow of electric currents in the ionosphere decreased and offset the strength of Earth's magnetic field (as detected on Earth's surface) by more than 10 percent.
