Diversity Lost in Space: Discrimination and Exclusion in Astrobiology

This study presents an analysis of diversity, equity, and inclusion in the U.S. astrobiology community. Using national survey data, we examined how gender, race, age, and career stage affect researchers' experiences with mentorship, funding, and career advancement. The results reveal disparities: female participants reported gender discrimination at seven times the rate of male respondents, and 85% of all respondents had encountered harassment. Nearly half experienced career interruptions, most commonly due to mental health challenges (57%), family obligations, or harassment. Other persistent barriers included difficulty meeting workplace expectations (84%), securing permanent positions (40%), and obtaining adequate funding (nearly one-third). Female researchers reported lower levels of workplace support and collegial respect than their male peers. While some institutions have begun implementing equity-focused practices, adoption across the field remains limited. Based on these findings, we recommend that institutions publicly report diversity metrics, establish targeted mentorship programs, and provide mental health support and parental leave policies. Addressing these systemic barriers is essential not only for ethical reasons but also for advancing astrobiology's mission, which depends on diverse perspectives and collaboration.
