What are personnel in the Space Force commonly referred to as?

Personnel in the Space Force are commonly referred to as "Guardians." This term reflects the force's mission to protect U.S. interests in space, emphasizing the role of its members as defenders of the nation in the domain of space. The adoption of this term symbolizes the dedication and responsibility of those serving in the Space Force, highlighting their commitment to ensuring space remains a safe and secure environment for all.

In contrast, the other terms do not specifically represent members of the Space Force: "Defenders" could apply to various military branches focused on ground or air defense, "Astronauts" refers to individuals who travel to space primarily for scientific and exploratory missions, and "Space Cadets" is often used in popular culture and is not an official term for military personnel within the Space Force.
