Earth neutral atmospheric density traced
Chinese researchers have achieved neutral atmospheric density in the altitude from 90 to 200 km
Beijing: Chinese researchers have achieved neutral atmospheric density in the altitude from 90 to 200 km, according to a recent research article published in the journal Advances in Space Research.
The near-space atmosphere is simultaneously influenced by solar and geomagnetic activities, as well as topography, weather, and gravitational waves, Xinhua news agency reported.
As a basic parameter to characterise the near-space atmosphere, the density of the near-space atmosphere can be used to analyse the physical mechanism of the sun-earth relationship and the coupling of the circle layer.
Space vehicles pass through the near-space atmosphere. The accurate measurement of near-space atmosphere density affects the precise orbiting, avoiding space debris collision and the re-entry control of spacecraft.
The X-ray Earth occultation realised tomographic scanning of atmosphere density in near space by using a satellite platform and effectively operated the global real-time detection.
