ESA Graduate Trainee in Jupiter radiations environment model for Juice science planning & operations

Job Requisition ID: 19286

Date Posted: 1 February 2025

Application Deadline: 28 February 2025 23:59 CET/CEST

Publication: External Only

Type of Contract: ESA Graduate Trainee

Directorate: Science

Workplace: Noordwijk, NL

Grade Band: F1 - F1

Location
ESTEC, Noordwijk, Netherlands

Our team and mission
ESA maintains a world-leading Science Programme with missions in heliophysics, planetary science, astrophysics and fundamental physics. Its mission is to 'Empower Europe to lead space science'. The Department for Science Operations and Office for Science Engagement and Oversight host together the scientists and engineers that oversee the space missions, from study to end of operations. It defines and develops the science operation systems for the missions and operates the missions in space, as well as archiving and curating their data during operations and beyond. Our main objective is to maximise the scientific output of ESA's space science missions for the benefit of humankind.

The Jupiter Icy moon Explorer (JUICE ) is the first large-class mission in ESA's Cosmic Vision 2015-2025 programme. Launched in 2023 and planned to arrive at Jupiter in 2031, it will spend at least four years making detailed observations of Jupiter and three of its largest moons, Ganymede, Callisto and Europa.

Field(s) of activity/research for the traineeship
Scientific space missions encompass many technical challenges, one of which being the radiation environment. The space environment around Jupiter that the Juice mission will encounter is one of the harshest in the solar system. Very high energy particles are trapped in the magnetosphere and can degrade the mission performances. This aspect needs to be carefully considered during each phase of the project and have multiple impacts on the mission design: spacecraft and instrument shielding, adjusted trajectory to limit the radiation dose over the course of the mission, adapted payload operations to protect the instruments when needed.

The goal of this project is to use the latest model of the Jupiter radiation environment to support the selection of the Juice trajectory and to prepare the future science operations planning. An updated radiation model will be available in 2025. The following activities are foreseen, under the supervision of the Juice Project Scientist, in collaboration with radiation experts, trajectory designer, and members of the Juice science operations center:

• learn about the Juice mission, science, payload, science planning and trajectory design, how radiation models are being developed and what are the effects of radiation on spacecraft and instruments;
• test of the Jupiter radiation model update and, using specific existing software, evaluation of the radiation dose level for a family of spacecraft trajectories in the Jupiter system with varying orbital inclinations;
• design and implementation of a system within the science operations center to visualise a selection of relevant Juice measurements (spacecraft engineering data, radiation monitor, etc..) to track the radiation environment;
• consolidation of the requirements for including the information on radiation (like radiation dose, energetic particles fluxes,…) in the science operations planning and implementation of these requirements;
• study of the radiation shielding of the Ganymede magnetosphere for future implementation in the science operations planning and assessment of future trajectories, by using an engineering radiation model specifically developed for this purpose.
