Last month we explored why dogs and cats, as much as we love them, aren’t likely to be the first pets we bring to Mars. This month we’re opening the door to everything else: insects, fish, rodents, reptiles, and more — and asking which companions might actually help future Martians thrive. With the help of Dr. Jamie Foster from the University of Florida, we dive into the surprising history of animals in space and why pets could play a vital role in mental health and wellbeing on the journey to Mars.
