Microgravity on the Space Station Makes It a Perfect Lab, Here’s Everything We’re Learning (Part 1 of 3)

Fish, mice, and worms have joined astronauts in space to be part CASIS’s mission to understand the effects of microgravity on the ISS. Join us in talking to Dr. Mike Roberts to learn more!


The Center for the Advancement of Science in Space (CASIS) works in partnership with NASA to manage the U.S. National Lab on the International Space Station. The laboratory offers a unique environment that’s super valuable to scientists by giving them access to a microgravity they can’t access from the ground.

Humans have been operating in the space environment for over 18 years now, and as a result, have provided us with new medical and material technologies. Microgravity can be hard on the human body, and the work done on the ISS has given us a way to study the effects of bone loss and how to better treat it on Earth. The microgravity environment of the lab also allows scientists to test the efficiency of new materials that could one day be used for spacecraft and satellites.

They also conduct experiments with animals, including mice, fish, and worms. Experiments conducted with mice give us a window into how reproduction over several generations would work in space, which could one day serve as an example when considering how human reproduction in microgravity would work.
