In this paper we showcase the importance of understanding and measuring
interdisciplinarity and other -disciplinarity concepts for all scientists, the
role social sciences have historically played in NASA research and missions,
the sparsity of social science interdisciplinarity in space and planetary
sciences, including astronomy and astrophysics, while there is an imperative
necessity for it, and the example of interdisciplinarity between social
sciences and astrobiology. Ultimately we give voice to the scientists across
all fields with respect to their needs, aspirations and experiences in their
interdisciplinary work with social sciences through an ad-hoc survey we
conducted within the Astro2020 Decadal Survey scientific community
