Tenders Are Invited For Phase 0/A System Studies Of The Keystone Mission

Tenders are invited for Phase 0/A System Studies of the Keystone Mission Keystone is one of the four candidate mission concepts for the twelfth Earth Explorer (EE-12), approved by PBEO at its meeting of 17 April 2024 (ref. ESA/PB-EO(2024)18). Keystone would provide the first direct observations of atomic oxygen in the altitude range of 50-150 km using a unique combination of limb-sounding techniques. These measurements together with observations of composition, temperature and winds would allow scientists to study the processes that drive the variability and energy balance of the mesosphere-lower-thermosphere region of the atmosphere, also looking at the impact of solar cycles and space weather. The procurement in subject includes the Phase 0 system studies and Phase A system studies which will be performed through a phased contract. Subject to reception of good quality proposals, it is intended to place two parallel contracts. Phase 0: the Phase 0 system study will cover allelements of the mission architecture: space segment (platforms and instruments), ground segments, operations and exploitation concepts. These studies will be based on the Agencys Statement of Work (SoW) and the Mission Assumptions and preliminary Technical Requirements (MATER). Risk retirement activities will also be identified and initiated within the frame of the study, to raise TRL of critical technologies. The expected duration of the Phase 0 system studies is 14 months from kick-off to closure of the MAR. The resultsof the Phase 0 will be used as input for the down selection of two EE-12 missions out of four to progress to phase A. If the mission is selected the second phase of the contract will be initiated, otherwise the contract will be terminated. Phase A: The Phase Asystem study will address all elements of the mission architecture, namely space segment (platform and payload), ground segment, mission operations and exploitation. The Phase A system study will be based on the Statement of Work (SoW) applicable from the beginningof the contract and the System Requirements Document (SRD) established by ESA and consolidated at the end of the phase 0. Relevant technology pre-developments will be initiated within the frame of the study, to raise TRL of critical technologies, with the aim toreach TRL 4 by the end of phase A, and with a final goal to reach TRL 5 by the end of phase B1. The expected duration of the Phase A system studies is 18 months from kick-off to final approval of all deliverables. The results of the Phase A will be used as input for the down selection of one EE-12 mission out of the remaining two to progress to phase B1. It is expected that Phase B1 will beplaced as a rider to the Phase 0/A contract of the EE-12 mission selected for implementation.
