"Predicting the First Animals to Inhabit the Moon and Mars"

NASA plans to establish a permanent lunar outpost and explore Mars, prompting consideration of which animals could help sustain ecosystems in space. Insects, fish, water bears, and crustaceans are among the candidates due to their potential for pollination, food production, and resilience to extreme conditions. However, the impact of reduced gravity on animal development remains a significant challenge, with simpler animals like insects and crustaceans likely to be more robust in space habitats. Research and engineering challenges persist, but these animals could play crucial roles in supporting future human settlements beyond Earth.
