Artemia from marine hatcheries to the outer space

Review: Abdel Rahman El Gamal (Founder of the website)

 

The inserted picture shows a brine shrimp tank that is typically found in most of marine hatcheries. This is based on the high nutritional value as well as the appropriate sizes of artemia species that suit the feeding requirements for the early stages of marine finfish larvae and the postlarvae of crustaceans.

Interestingly, artemia has been among the animals taken to the outer space during 1970s through the US Apollo 16, and Apollo 17 missions as well as on the former Soviet Union Cosmos 782 and Cosmos 1129. The brine shrimp cysts were subject to series of experiments with various objectives whereas the overall studies targeted to understand the impact of space environment on the experimental animals including brine shrimp and in particular to explore possible effects of cosmic rays -if any- on artemia and relate that to the possible impact of such radiation on astronauts with an ultimate goal of making the space flights safer for humans. During particular mission (e.g. Apollo 16 and 17), the brine shrimp cysts had a round-trip from earth to the moon and back.
