Geraint Jones, UCL Mullard Space Science Laboratory
In 2019, the European Space Agency selected its latest planetary mission: the multi-spacecraft Comet Interceptor. The project’s primary goal after launch in 2029 is to characterise, for the first time, a long-period comet, preferably approaching the Sun for the first time. This planned flyby promises to provide us with valuable data to complement information gathered by all previous comet missions; all past projects have studied comets that have been altered by passing near the Sun many times. The mission will comprise a main spacecraft and two smaller probes, one of which will be provided by the Japanese space agency, JAXA. We’ll explore the challenges of planning a mission to an unknown target, how our comet target is to be selected, and the exciting measurements that the mission team plan to make. The mission website is at www.cometinterceptor.space.

Mini-JPAS survey, a precursor to the JPAS survey, observed a 1 deg^2 strip with 56 J-PAS filters in 2018 and 2019. Based on the recently accepted overview paper, we take a look at the status and quality of the mini-JPAS observations and catalogue to see how the full JPAS survey should turn out.

Dr Margit Aun
In the presentation, Margit Aun will introduce remote sensing of the atmosphere in the Copernicus program. She will talk in more detail about the mission of the Sentinel-5P - goals, products and current status. She will present the results of the first extensive validation of Sentinel-5P ultraviolet radiation products. Finally, she will provide a short overview of the new atmospheric missions planned for the coming years - CO2M, Sentinel-4 and -5. Seminar is in Estonian.
