Announcement of Opportunity for
Interdisciplinary Scientists and Guest Investigators
in the ExoMars 2022 mission


Please check the Updates section at the end of the page for any changes since the AO was issued.

3 December 2020

This Announcement of Opportunity (AO) solicits the participation of the scientific community as Interdisciplinary Scientists or Guest Investigators in the ExoMars 2022 mission, to augment the scientific return of the mission as a whole.

The ExoMars programme is an international collaboration undertaken by ESA and Roscosmos, with NASA contributions, to develop and launch two missions. 

The first ExoMars mission was launched on 14 March 2016 and arrived at the red planet on 19 October 2016.  The second ExoMars mission, scheduled for launch in 2022, will deliver two science elements to the martian surface: (1) Kazachock, a surface platform (SP) instrumented to perform environmental and geophysics measurements; and (2) Rosalind Franklin, a rover tasked with conducting a search for signs of life.

The aim of this AO is to appoint up to five Interdisciplinary Scientists (IDS) and up to eight Guest Investigators (GI) for the ExoMars 2022 mission. The IDSs and the GIs will be appointed until the end of the nominal mission (lasting approximately 211 sols); the appointment could be renewed in case of mission extension. An IDS or GI appointment is ad personam. ESA will not fund the activities of the IDSs or the GIs (travel costs to attend meetings, etc.) and each proposer is responsible for securing their own funding.

This call is open to scientists in institutions based in ESA Member States, Canada, and Russia. However, specific expertise not present in ESA Member States, Canada and Russia could be covered by scientists from other countries. Team members participating in a team supporting an IDS can be from any country.  While Principal Investigators (PIs) and Co-PIs of the ExoMars instrument teams are excluded from this call, Co-Investigators (Co-Is) are eligible for IDS and GI positions.​​​​​​​

Full details, including the tasks of an IDS or GI, requirements for the proposals, and evaluation criteria, can be found in the Announcement of Opportunity for Interdisciplinary Scientists and Guest Investigators in the ExoMars 2022 mission document.
