The forthcoming Kerbal Space Program update, 1.10 features a major collaboration with the European Space Agency to bring the Rosetta and BepiColombo missions to the game in the form of playable missions and special parts.
I sat down to play through the mission while talking to the real Manager of Spacecraft Operations for Bepicolombo - Elsa Montagnon. Obviously because of quarantine rules this had to be an entirely digital collaboration, but she explains a lot of details of how the real spacecraft is managed while I tried to navigate my way through multiple gravity assists to reach the innermost planet.
Thanks to Elsa for joining me
