Comet Interceptor is an ESA mission in cooperation with the Japan Aerospace Exploration Agency (JAXA). It aims to characterise a long period comet, which could potentially be a dynamically new comet, or an interstellar object. The mission was adopted by the Science Programme Committee in June 2022 as the first "F" mission in the Science Programme. A Science Working Team (SWT), appointed by ESA in coordination with JAXA, advises ESA on all aspects of the mission potentially affecting its scientific performance. The composition of the SWT is defined in the Science Management Plan (SMP). The SWT is supported by Working Groups (WGs), in specific scientific and/or science operation areas, relevant for the mission.

Through the present Call, the ESA Director of Science invites scientists based in ESA Member States and Japan to apply for the Interdisciplinary Scientist positions in the Comet Interceptor mission.

Lead Scientists and Co-Lead Scientists of the Comet Interceptor instruments, other scientists leading or involved in the (programmatic, scientific, or technical) management of the Comet Interceptor instruments or being responsible for hardware or software development and procurement activities, as well as other Science Working Team members, are not eligible, while Co-Investigators of instrument teams may apply to become IDSs.

Full details of this Call can be found in the Announcement of Opportunity for Interdisciplinary Scientists in the Comet Interceptor mission document.
