Jospeh Stromberg with a story and a GIF on what happens to ants in space.
The formal experiment was a test of whether the ants could coordinate to search their environment, as they do on Earth. At the start, they were housed in a small corner of their plastic box, but over the course of a few minutes, astronauts removed barriers from it, allowing them to access new territory.
A comparison group of ant colonies on Earth were able to spread out and survey the entire environment within five minutes. Because of the difficulties of microgravity, the space ants weren’t able to cover all the territory within the same time period, but they still managed to spread out and see most of it.
Wherever they are, the ants manage to get around. So, why not gather all the earth’s cockroaches and send them into space as an experiment to see if they can find their way home.
