The animals are being launched into the cosmos as NASA researchers attempt to learn more about how the conditions of spaceflight can affect biological organisms and, by extension, future astronauts.
The two space probes will study Venus, a scorching hot world that may have once been like Earth. NASA chose the Venus missions over other candidates, such as trips to the moons of Jupiter and Neptune.
NASA announced Friday that it would be increasing operational testing on its Ingenuity helicopter following four successful test flights off the surface of Mars.

Jet Propulsion Laboratory project manager MiMi Aung gave an enthusiastic two thumbs-up and then clenched fists before a roomful of engineers erupted in applause.
The successful deployment of Ingenuity brings NASA one step closer to its first attempt at testing the possibility of powered, controlled flight on another planet.
Lunney, who played an integral role in the agency's Apollo program, died Friday. He was credited for his quick decision-making during the race to save the lives of the Apollo 13 astronauts.
