Area of research:
Have you (almost) completed your degree studies? Are you inspired by space exploration and keen to pursue a career in this exciting field? If so, perhaps you should take a closer look at the German Trainee Programme. Organised by DLR, it offers you the chance to work shoulder to shoulder with experts from the 22 member states of ESA – keeping your finger on the pulse of Europe‘s space programmes. Over a period up to 24 months, you will actively contribute to the latest research and/or technology projects. This is complemented by a generous scholarship. What better way to launch your career in international space business? The next GTP commences on 1st February 2020.
This is your opportunity to join the team at ESOC – Darmstadt, Germany
Mission Analysis ( GTP-2020-OPS-GFA)
ESA’s Mission Analysis Section is based at the European Space Operations Centre in Darmstadt. Mission Analysis has a key role in the definition of ESA missions around the Earth, the Moon, another planet or its moons or a libration point. The target orbit, the transfer, the launch, the mass and propellant budget, the optimal manoeuvre strategy using high or low thrust propulsion, and numerous other products that are vital for the design of a spacecraft are derived by Mission Analysis. Trainees in the Mission Analysis Section are members in project teams and work on demanding tasks with a high level of autonomy, they may provide support to feasibility studies for future ESA missions or contribute to the planning or operations of an actually flying mission that is being operated by ESOC.
In the frame of Planetary Defense, it is investigated how a thread caused by a Near Earth Asteroid or any other Potentially Hazardous Object can be mitigated. A key input to this endeavour is the statistical knowledge covariance of the Earth impact probability at the predicted impact date, that is typically assessed using ground-based measurements of the asteroid. Recent work has investigated the benefit of using a dedicated fly-by mission in combination with optical on-board measurements and ground-based Range and Doppler in order to improve the knowledge of the Earth impact probability. Preliminary results show that two consecutive fly-bys can improve the knowledge tremendously. Further analysis is needed in order to improve the dynamical models of the covariance analysis. In particular, one open question is how the so-called Yarkowski effect will deteriorate the initially gained knowledge of the asteroid over time. This analysis shall be implemented in the New Orbit Software developed in-house at ESOC.
