Diversity is difficult to measure and quantify, given all the aspects and shapes it takes, yet it is easy to witness and observe the lack of it in many fields including the space sector.
If the space sector and all its disciplines should be used to help improve life on earth and observe it (amongst other purposes), shouldn't it be represented by all terrestrial individuals equally? In an ideal world, yes! But history and social biases have prevented our progress towards this perfect world, and we find ourselves today with a space sector still dominated by cis white-male individuals.
