As part of this effort, this new board game was created by the Quantis company. But they are busily learning about the hidden environmental costs of space missions.ĮSA’s Clean Space initiative – tasked with reducing the environmental footprints of the space industry both on Earth and in orbit – includes a dedicated ‘ecodesign’ element. “It might not look like a training exercise: space engineers sitting around a meeting table, throwing down cards on a board game.
