This paper is the result of an international, intercultural and interdisciplinary study on the outreach challenges of preparing students between the ages of 15 and 25 years for a career in the space industry. This qualitative study aimed to find and compile the best outreach practices and recommendations for engaging young people in an increasingly diverse world. Traditionally, space outreach has been biased and limited to a small number of careers in leading nations in the space industry. With the industry undergoing huge changes, new space actors are emerging even in nations that lack a national space program. Thus a new challenge for outreach professionals is to paint a realistic and updated picture of the paths towards a career in space in this new industry for their young audience. Not only have opportunities for space outreach grown in new geographies, with their own cultural and lingual characteristics, but also in traditional space nations, which are driving towards a more inclusive and diverse communication to their audiences.This paper is built around a literature study into outreach for diversity in the space industry, plus a survey among space outreach practitioners around the world. The analysis of this survey, in the context of literature findings, leads to new insights into outreach practices for new space audiences, the challenges involved in engaging these new audiences, and in providing them with an objective perspective of career opportunities in the local and international space sector. The analysis includes topics like the diversity of role models and the advantages of using varied channels to reach young audiences. The paper concludes with a set of practical recommendations for space outreach professionals and researchers.
