The Pros and Cons of sending animals to space.

This was a research assignment.

I set out to answer a variety of questions about animals in space, including the timeline of previous missions, and I also researched the impact.

Why would we send animals to space?

• We were unsure of what would happen to us

• There was a theory on we could not survive long periods of time of weightlessness

• American and Russian scientists used animals to test each other's ability to bring them back alive

• Animals were used to make sure humans could survive in space

• Other questions relating to the body and brain’s reaction were wondered about:

• Example: There was a mission objective to investigate the effect of space flight on brain states, behavioral performance, cardiovascular status, fluid and electrolyte balance, and metabolic state. They sent a monkey with a planned 30-day mission, he died just under 9 days in orbit. He died from a heart attack because of dehydration.

• Example 2: A Soviet rocket pioneer and his biomedical expert used animals to help them design a cabin that could carry a human into space.

• We sent bullfrogs to space to study how the inner ear balance system adapts to weightlessness.

• Example 3: 2 garden spiders were sent to space, to see if they could spin webs there. How would we send animals to space?

• Some animals did training.

•

Monkeys, chimps, flies, tortoises, Water bears (Tardigrades), dogs, rabbits, mice, rats, guinea pig, Cats, fish, newts, geckos, worms, cockroach, squid, and jellyfish.

What would be the animals’ reactions? * Information is found in videos and are my observations from them. * Most of the animals were strapped (mostly larger ones, dogs, chimpanzees, monkeys). Information describes their behaviour in zero gravity. * Different animals = different reactions. * Example: Cats land on their four legs when falling. In zero gravity those rules apply weirdly; they’d either land but float back up or be floating in the air while rotating around with their legs kicking wildly. * Example 2: Snakes would try to move around only to tangle themselves up, float, and rotate around. * Example 3: Mice would run around in their cage while floating and rotating around too.

The Pros and Cons of sending animals to space

• Pros:

• Able to save a lot of human lives because we sent animals instead of humans

• More cost-effective to send animals

• Able to make a better living space for humans now, making it a healthier and safer reality.

• Able to study the adaptations of these animals and use it as a base to understand our survival chance.

• Cons:

• It’s unethical and cruel to risk the lives of animals for our own purposes.

• Some animals were abused as part of their ‘training’.

• After they were sent to space, they either died there or came back only to shortly die or be euthanized after.

• Example: A cat from France was killed to have an autopsy of her brain, from being implanted with electrodes which recorded her neural impulses.

• They suffered distress and pain.

What would happen if we sent animals to space?

• Sending animals to space is a big responsibility

• Helped us understand what would happen to humans

• Helped us answer our questions

• Sent them by shuttles, rockets, and spacecrafts

• We sent different species, each with different biologizes

• Gave us a large understanding of adaptations

• Animals died from being chosen to be sent to space

• Some animals came back unharmed

• Different animals had different reactions to the environment of space (confusion, fear, etc.)

• Lives were sacrificed for us; we should honour them.
