SPACES is mainly dedicated to carrying out scientific studies leading to demonstrate the suitability of the CAIRT mission to meet its scientific goals and to generate scientific and societal impact. CAIRT is one of the four space mission candidates of the 11th Earth Explorer (EE11) of ESA that will observe simultaneously from the middle troposphere to the lower thermosphere at high spectral resolution and with unprecedented horizontal and vertical resolution.

In addition, this project continues our previous efforts on improving our knowledge of solar influences on Earths middle atmosphere and climate and our studies on exo-atmospheres: escape and sub-Neptunes.
