Atmospheric modelling of planets within our solar system and the impact of space weather, are based on data sets that are sparse and disparate (different sensors, missions, altitudes, seasons, time, and latitudes). This disparity is making such modelling particularly difficult. If we were able to fully understand the impact of space weather on Mars and correlate such data with what’s happening on Venus and Earth, we might come a long way in understanding the impact of space weather on our own planet’s atmosphere, at a time when climate change is of the utmost importance.
Cross-mission and cross-planet correlation of data would be a major step towards this direction if the data could be normalised. Such comparative data analysis is particularly complex for humans.
But with recent successes of Artificial Intelligence (AI) in astronomical discoveries (discovery of exoplanets that were undetectable by humans), the use of AI could be a solution in achieving the impossible.
Utilising AI supercomputers, and computing experts, it might be possible to formulate such an AI task.
The purpose of this event is to bring together plasma-physicists and AI computing experts in a first attempt to create innovative new solutions that could tackle this space weather problem.
Utilising AI supercomputers, and computing experts, it might be possible to formulate an AI task / deep-learning algorithm that could analyse and make sense of sparse space weather data, and try to correlate in order to create a model that could prove useful in understanding space weather on Mars, but furthermore understand Venus and its runaway greenhouse effect, thus creating an overall understanding of space weather in multiple planetary bodies. This would assist in understanding our own atmosphere and the impact of solar weather to it, and subsequently identify methods to mitigate or reverse climate change.
We are requesting to supercomputing experts and industry to be involved with infrastructure and experts in this challenge that will kickoff with introductory meetings in the next weeks/months (as preparatory activities) leading to a culmination at the Cospar 2022 General Assembly in Athens, where we aim to hold an experts summit from both sides (super-computing/deep-learning/AI and plasma-physics/space-weather) in order to agree on possible methods to tackle this problem. We aim to identify datasets and algorithms that would then be utilised in a first such pilot task.
To better understand the behaviour of our planet’s atmosphere we need to benchmark theories and measurements on planetary realities with fewer parameters. Mars is considered a perfect example of simplified terrestrial high atmosphere. Also, the study of the evolution of the atmosphere of Mars, from a thick humid state to today’s thin dry state, may shed light on possible evolutive paths of Earth’s atmosphere. Mars is the most Earth-like planet we’ve ever examined up close, besides our own.
Space missions to Mars over 50 years have collected many measurements, beginning to shape a new view of modern and past processes on Mars, with the upper atmosphere as a major contributor to Mars' climate evolution.
The Mars Upper Atmosphere Network, based in Cyprus and hosted by the Cyprus Space Exploration Organisation, coordinates above efforts. Using combined multi-spacecraft data from all missions orbiting Mars we aim to improve human understanding of the global coupling of the different layers of Mars atmosphere, the relationship between lower atmospheric dust, water vapor and understanding the development of Mars atmosphere over time. Also, to achieve an understanding of the relation between middle atmospheric water content and observed H outflow in the upper atmosphere, and to develop a novel understanding of atmospheric loss process (via a macro-model of atmospheric interaction with the solar wind) and the dynamical behaviour of the Mars Upper Atmosphere and its response to solar wind erosion.
We’ll focus on EUV and non-EUV heating sources, Day/Night Changes, Homopause / Mesopause variability, Wave coupling with lower atmosphere, Photochemistry and escape of water vapor. Understanding of this complex phenomenon on Mars will help us better understand the same processes on our planet trying to separate the role of the Sun and the solar wind in the ultra-complex process of global warming, bringing a major impact in preserving / improving the impact of space and atmospheric weather on everyday life.
