Landgraf Markus - Gaia
Gaia was proposed in 1993 and since then, many people have been involved in the Gaia mission, whether at ESA, at industry side or at one of the institutes involved in the Gaia data processing. The Gaia Data Processing and Analysis Consortium (DPAC) is a collaboration which consists of around 450 scientists and engineers.
The list of Gaia contributors presented here should not be considered a complete representation of the entire consortium and should not be considered as a list of currenly active people on the Gaia mission. A more complete list of Gaia contributors that were involved in the creation of the Gaia catalogues can be obtained from the author lists of the Gaia Collaboration overview papers (for Gaia Data Release 1 see here, for Gaia Data Release 2 see here, for Gaia Early Data Release 3 see here, for the full Gaia Data Release 3 see here, for Gaia Focused Product Release see here). A history of contributions to the Gaia mission can be found from the acknowledgements given with each data release.

Dr. rer. nat. Markus Landgraf is the mission analyst for Gaia. In mission analysis we provide the mission design, that is the trajectory from launch to operational orbit, time-lines and associated products like ground-station visibility schedule, delta-v budget, launch window, etc. We are in the mission since a very early stage normally all the way to the end. Our role gets a little less visible after launch as the operational responsibility for the orbit is taken over by flight dynamics.
Personally I am fascinated by the science of the Gaia mission. As a natural scientist I share the ambition to find new things in nature by performing a simple measurement (like the measurement of the position of stars in the sky) very precisely (which then makes it much less "simple"). So I am highly dedicated to finding the best possible orbit for Gaia, the current baseline being a 15 degree Lissajous orbit around the night-side Lagrange point of the Sun-Earth system, which is reached from the launch by Soyuz from Kourou by a fast transfer comprising two deterministic manoeuvres. Go Gaia!
