SpaceX is launching its 22nd cargo resupply mission on 4 June, which will carry science experiments supplies, including 128 baby luminescent bobtail squid and 5,000 tardigrades.
The research will investigate how zero gravity affects the symbiotic relationship between the squid and the beneficial microbes that they host. On the other hand, the tardigrades, a species famous for tolerating extreme environments, will be studied for effects of spaceflight on biological survival.
Other space station experiments waiting on the resupply mission revolve around developing robot drivers, producing tougher cotton, and the development of kidney stones in zero gravity.
