    Before man had attempted to reach space, scientists were unsure if living creatures could survive in a microgravity environment. Animals were originally sent into space to see if manned spaceflight could be pursued, and still today they are sometimes used for research purposes. Should animals be used in spaceflight testing?

    In the 1940s, scientists needed to investigate the effects of space travel on living organisms. From the late 1940s to 1960s, the U.S. launched into space fruit flies, mice, and monkeys of various species so scientists could monitor their vital signs and reactions to microgravity and radiation. The Soviet Union conducted similar tests with dogs, including stray dog Laika, the first animal to enter orbit in 1957. In the following decades, France, China, and Japan also launched animals into space to study their reactions to the space environment.

    Wide arrays of animals have been used for space research. Other animals flown in space include chimpanzees, guinea pigs, frogs, rats, cats, tortoises, fish, newts, shrimp, sea urchins, several types of insects, and more. Tests have also been conducted on various types of eggs.

    Because of the success of animal flights, humans have been able to explore the depths of space. NASA was able to send Alan Shepard into space just three months after learning from the successful spaceflight of Ham the chimpanzee in 1961. Animal research has helped scientists understand motion sickness, the effects of microgravity, and more. In addition, many discoveries have been made about animals’ instinctive behaviors while in this unfamiliar environment.Animals are only sent to space when absolutely necessary, however. Scientists prefer to research with computer models, or by involving astronauts directly. When animals do go to space, the Institutional Animal Care and Use Community helps provide the safest, gentlest solution for their care. The U.S. Department of Agriculture’s Animal Welfare Act and the Public Health Services Policy Act also help protect animals traveling in space.

    What is your opinion? Should animals be used for spaceflight research? Are any other alternatives available? Share your thoughts in the Opinion Corner forum.

    yes because do you want a human to die or do you want a monkey to die in an accident.

    NOOOOOOO!!!!!!!!!!!!!!!!! You know they send the poor little animals to space not thinking about what the animals would say if they could talk! Besides they want to do the research! The animals don't care about space!

    no, animals should not be sent into space because it's people who want to know whats up there, so animals shouldn't have to risk their lives

    that's so very wrong that animals should up to space and then they might die if there oxygen helemt comes off and that's so sad if a animal/ living thing should be in space for reseach

    I don't think that poor, little animals should be used as space researchers because if something goes wrong, the animal could pay because if an experiment goes wrong, maybe the animals are the victoms of the wrong experiment. Animals should be free in the wild or in a cozy home as a domesticated pet, or pets.

    NO!!! I don't think so at all! Animals should be free, not to be tested!!!
