It was because space at the time was an unknown as were the effects on life. Animals were used rather than risk the lives of people.
To measure the effects of space travel on animals before risking a manned space flight. In the early stages of a project, animals are use as a method of risk management. In other words, if plan "A" did not work, at least there would not be a loss of human life.
NASA has sent various animals to space for scientific research, including fruit flies, spiders, monkeys, mice, and most famously, chimpanzees. These animals were used to study the effects of space travel on living organisms and to gather valuable data for human space exploration.
No I hope not
yes,the medieval people use birds to send messages.
Animals can send visual messages through body language, such as postures, gestures, and facial expressions. They use these cues to communicate their intentions, emotions, and social status to others within their species. Additionally, some animals use color patterns or displays on their bodies to attract mates, warn predators, or establish territory.
to check if animals can survive there
To check that it would be safe to send humans at a later stage.
They sent a Russian dog to space, they sent a chimpanzee to space and they sent/send humans to space.Neil Armstrong, Buzz Lightyear (whatever his last name is)All those people. XD
to send people to space
Yes because the animals are poor.
they send people to space or by the space station
No, it is not against the law to ship animals on their own. People ship dogs and other domestic animals on their own in crates on planes. They do this to send them to the buyer instead of driving all the way to give them their purchase.
the first people/ nation to send some form of satellite into space is the russians with thesputnik 1
We learned more about space and that we can send people up there.
NASA occasionally sends out space probes instead of humans because astronauts could not survive on some of the places that space probes are sent to.
Because often they have friends and family that protest violently to send people into space, ESPECIALLY without any protection. (Many people burn up from friction with the atmosphere before they even reach space)
Yes, to further the exploration of space, and medical research.
