A person, computer system, or device responsible for navigating a spacecraft or celestial vessel through space using astronomical calculations and observations.
From astrogate + '-or' (one who does). This term is used in aerospace contexts and science fiction literature to describe specialized navigation operators or systems.
An astrogator is like a cosmic pilot—but instead of flying through air, they're calculating paths through gravitational fields; some astrogators are humans, but increasingly they're sophisticated computers that never sleep.
Historically, -tor/-trix suffixes marked masculine/feminine agent roles; 'astrogator' assumes male navigator by default, while 'astrogratrix' remained obscure. Space exploration and STEM navigation roles were male-dominated until late 20th century.
Use 'astrogator' as gender-neutral term for any navigator, or specify 'astrogation specialist' to avoid gendered agent nouns entirely.

Women like Katherine Johnson, Mary Jackson, and Dorothy Vaughan performed critical astrogation and trajectory calculations for NASA; Valentina Tereshkova and Sally Ride pioneered space navigation roles historically erased from astrogator terminology.
