Study of organic aerosols formed in cold plasma: experimental simulation of a nitrogen and non-nitrogen based atmosphere.

After the explorer probe of the voyager 1 and the voyager 2 missions that flew over Jupiter and Saturn, The Juice mission « Jupiter Icy moons Explorer » was launched by an Ariane 5 rocket on October 2023. It will provide the first observation of the Jupiter’s atmosphere. Indeed, the aerosols and the atmosphere of this planet initially perplexed researchers. Several research studies have focused on Titan aerosols following the Cassini mission. In this way, we built on the legacy of this Titan model to discover the Jupiter science. This research topic is dedicated to the comparative study of aerosols analogue of Titan, which is the second largest Saturn satellite, and aerosols analogue of Jupiter, which is the largest planet of the solar system, to gain a better understanding of the difference between the appearance of organic aerosols in nitrogen and non-nitrogen based atmospheres. For this purpose, in this work, we first synthesized aerosols analogues by experimental means using Cold Plasma, and second then analyzed them by Scanning Electron Microscope (SEM), Infra-Red (IR). The result revealed the presence, possibly, of the different organic molecules and it showed a difference in an average size and a geometric shape between the two planetary analogues.
