Instrument pre-development for FLEX mission
FLEX (Fluorescence Explorer) has been recently approved by the Earth Observation Programme Board as the next Earth Explorer 8 mission. The contract for the Phase B2/C/D/E1 of the payload is currently in the negotiation phase with Leonardo Company (prime contractor) and OHB AG System (sub-contractor). The FLEX pre-development has been addressed from the very beginning by ESA toward an experimental validation of the optical concept, the related alignment and test procedures and the early risk retirement of the most critical technologies as for instance detectors and gratings. An extensive breadboard development has been initiated since the phase A/B1 study of the mission, and its refurbishment is currently in progress for an Elegant BreadBoard (EBB). The complete development and successful test of the EBB is part of the FLEX instrument development plan and it is considered by ESA a key aspect for the success of the FLEX project. This paper will provide first a very brief overview of the mission objectives and a description of the instrument, in particular concerning the High Resolution Spectrometer designed by Leonardo and the Low Resolution Spectrometer, recently optimised by OHB System AG. A full description of the optical design and performances of the other subsystems is not part of this paper because subject of previous comprehensive publications. The pre-development activities are then addressed in more detail and the current status of the EBB is presented.
