Question

Do you agree that animals were used in space exploration from the 1940’s-1990’s? What might the consequences have been if they didn’t use the animals during that time?

Answer 1

yes

Step-by-step explanation:

Sending animals to space began as a way to make sure that human astronauts could survive in space at all. As spaceflight programs began to evolve in the 1960s and 1970s, space offered scientists the opportunity to "turn off" gravity, a variable they could never fully eliminate on Earth

Answer 2
