0 a satellite (= a device sent up into space to travel around the Earth or another planet, etc.) designed to carry plants or animals, for collecting scientific information about the effects of space on living things:
Tissue from rats flown on the biosatellite for 12.5 days was compared to the same tissue of control animals kept in a ground-based laboratory.
She studied the evolution of insects and helped set up experiments for the first biosatellite for NASA.
The goal of the biosatellite programme was to send the mice into near-Earth orbit inside a one-metre space ship that would spin to create artificial gravity to simulate that on Mars.
