The First Dog in Space Fact Sheet The First Dog In Space The First Cosmonaut The first living creature to orbit the earth from space was not a human being. This journey was instead made by a stray dog from the streets of Moscow named Laika. Laika orbited the earth in a spacecraft named Sputnik 2 which launched into outer space on 3rd November 1957 – that’s almost 12 years before Neil Armstrong became the first man to walk on the moon. The Space Race In the 1950s, two countries were locked into a competition we now call the Space Race. The United States and the Soviet Union each wanted to be the first to explore deeper into space. The Soviet Union took an early lead in the Space Race when it became the first country to launch an artificial satellite into space on 4th October 1957. The First Dog In Space | Page 1 copyright 2019 Fact Sheet The Soviet leader, Nikita Khrushchev, was keen to build on this early advantage. He ordered his scientists to build a ‘space spectacular’ which would stun the world. Khrushchev also wanted this next flight to launch on the 7th November 1957, the 40th anniversary of the October Revolution. To create a ‘space spectacular’, the Russian scientists decided to launch a dog into orbit. Early flights had sent twelve dogs on suborbital flights and the scientists had been building towards sending a dog into space for some time during 1958. This new launch date would give them less than four weeks to design, build and launch their new spacecraft. Whatever they made would be a rushed job and they knew that they would not be able to return the dog safely to Earth. Laika The scientists believed that a stray dog would be the ideal animal to test out the flight before allowing a human into a spacecraft. A stray dog growing up on the streets of Moscow would be familiar with the cold and hunger it would experience in space. Three dogs were found: Laika, Albina and Mushka. Laika was a part-husky mongrel who was around three years old and weighed 6kg. Vladimir Yazdovsky – who was in charge of the training of the dogs – described her as being “quiet and charming” and she soon earnt several nicknames from the Soviet workers, including Little Curly, Little Lemon and Little Bug. Training Training for the dogs was hard. To get them used to the confines of the small spacecraft, the scientists placed them in cages which got smaller and smaller over the weeks. This made them very unhappy and restless. The First Dog In Space | Page 2 copyright 2019 Fact Sheet The dogs were also placed in centrifuges. When a spacecraft launches into space, the astronaut encounters huge pressure caused by the acceleration of the craft as it blasts into space at extreme speeds. To prepare the dogs for this, the centrifuges spun them around very quickly to simulate the acceleration of a rocket launch. To get them used to the sound of the launch, the dogs were also placed into machines that mimicked the loud noise. In space, the dogs would need to eat a special high-nutrition gel instead of proper food, so they needed to be trained to get used to this. Vladimir Yazdovsky chose Laika to journey aboard Sputnik 2 with Albina as her reserve. The third dog, Mushka, would test instruments on the ground. Shortly before the launch, one of the scientists took Laika home to play with their children. He knew the dog did not have long to live and wanted to do something nice for her. The Flight The dogs travelled to Turatam, where the launch was to take place by plane. Three days before the launch, they were placed into capsules to get used to the feeding systems. Turatam in late October was very cold and a heater was connected to the capsules to keep the dogs warm. Before closing the hatch door, one of the technicians kissed Laika’s nose and wished her luck. The First Dog In Space | Page 3 copyright 2019 Fact Sheet It is uncertain what time Laika’s capsule took off, with some reports giving 5:30am or 7:22am. The instruments showed that Laika was very stressed. There had been some difficulty in separating parts of the rocket and, during this, some of the insulation had come loose, making the capsule temperature hotter than planned. It was only after three hours of weightlessness when Laika’s pulse rate was shown to settle down. However, Laika was still managing to eat her food. After five to seven hours, there were no further life signs being recorded from Laika. Her cabin had overheated after its fourth orbit. On April 14th 1958, over five months after its launch and after more than 2,570 orbits, Sputnik 2 returned to Earth, disintergrating during re-entry. Laika’s legacy Following Laika’s journey into space there was a lot of debate about whether or not it was right to send animals into space in the place of humans. There were many protests and demonstrations around the world. Any future space missions involving dogs were designed so that the animals could be returned to Earth safely. A statue of Laika was created in 1997 and placed outside the Russian cosmonaut training facility. A further monument was unveiled in 2008 outside the research facility where she was trained.

    The Space Race Aims: To arrange the key events of the “Space Race” in chronological order. To decide which country won the Space Race. Space – the Final Frontier “Space” is everything Atmosphere that exists outside of our planet’s atmosphere. The atmosphere is the layer of Earth gas which surrounds our planet. Without it, none of us would be able to breathe! Space The sun is a star which is orbited (circled) by a system of planets. Earth is the third planet from the sun. There are nine planets in our solar system. How many of the other eight can you name? Neptune Saturn Mars Venus SUN Pluto Uranus Jupiter EARTH Mercury What has this got to do with the COLD WAR? Another element of the Cold War was the race to control the final frontier – outer space! Why do you think this would be so important? The Space Race was considered important because it showed the world which country had the best science, technology, and economic system. It would prove which country was the greatest of the superpowers, the USSR or the USA, and which political system was the best – communism or capitalism. https://www.youtube.com/watch?v=xvaEvCNZymo The Space Race – key events Discuss the following slides in your groups.

  • The Ethics of Animal Research – Teacher Notes
    The Ethics of Animal Research – Teacher Notes The previous lesson showed the extensive use of animals in the early days of space research and even today to further our understanding of the space environment. This raises important questions about the ethics of using animals in research. The use of animals in scientific experimentation has always been, and will always be a controversial subject. It is however an unavoidable fact that without animal research we would know far less about biology, diseases and medical conditions that affect humans and other animals. While researchers agree that animals should only be used when there is no known alternative and they should be treated with humane respect to avoid suffering, the scientific community continue to agree that the historical use of animals in research has allowed the development of medical treatment, surgical techniques, vaccines and the advancement of science in other areas. As we know animals were used extensively to serve as surrogates for human beings in the early days of spaceflight to learn vital information about the environment. In recent times, although animals continue to be used in space research, valid arguments about animal suffering have led to great improvements in their treatment. It is estimated that between 50 and 100 million animals are used in research experiments every year. Animals used in testing come from a variety of sources. While many animals, particularly worms and rats, may be purpose bred for testing other animals are still caught in the wild. Opponents to animal testing argue that it is cruel and unnecessary, that the results never reliably predict the reaction of human physiology and that animals have the same right as humans not to be used for experimentation.

Revised by Jennifer Mulholland and Renée Sporre- Willes / Original version: (EN). ORIGIN : Russia. DATE OF PUBLICATION OF THE OFFICIAL VALID STANDARD : 13.10.2010. UTILIZATION : Hunting dog for all-round purposes. FCI-CLASSIFICATION : Group 5 Spitz and primitive types. Section 2 Nordic hunting dogs. With working trial. BRIEF HISTORICAL SUMMARY : This is a Russian breed of hunting dogs from the European forest areas of Russia. The first record about northern ear-pointed dogs was published by A. A. Shirinsky-Shikhmatov in the “Album of northern sledge dogs-laikas” in 1895. The dogs mentioned therein were named Cheremis and Zyrianskiy Laikas. The breed was limited to the regions of Komi, Udmurtia, Arkhangelsk , Yaroslavl , Tver, Moscow and some other areas of Russia. In 1947 the off-spring of Arkhangelsk, Komi, Karelia, Votiatsk and other Laikas were united into one breed under the modern name of: – Russian-European Laika. The breed standard for Russian-European Laika as a purebred dog was approved in 1952. The correct modern type of Russian-European Laika, as a recognized purebred dog, was not achieved by breeding different Laikas off- spring; it is the result of selective breeding over a long period of time GENERAL APPEARANCE : Medium sized dog; of medium to strong built. FCI-St. N° 304 / 02.03.2011 3 The overall impression is that of a square built dog, the length of the body (point of shoulders to point of buttocks) being equal to the height at the withers; however, the length of the body may be slightly superior to the height at the withers.

  • What the Dogs Did: Animal Agency in the Soviet Manned Space Flight
    BJHS: Themes 2:79–99, 2017. © British Society for the History of Science 2017. This is an Open Access article, distributed under the terms of the Creative Commons Attribution licence (http:// creativecommons.org/licenses/by/4.0/), which permits unrestricted re-use, distribution, and reproduction in any medium, provided the original work is properly cited. doi:10.1017/bjt.2017.9 What the dogs did: animal agency in the Soviet manned space flight programme AMY NELSON* Abstract. This paper examines the agency of the dogs used to develop the Soviet manned space flight programme by considering what the dogs did as experimental subjects, as dog technolo- gies, and as individual dogs in the context of the historically conditioned practices of Soviet science. Looking at how Soviet space researchers refined Pavlovian behaviourism and inte- grated it into a complex engineering project helps clarify the conditions under which the dogs worked and the assumptions that guided the human researchers. The paper uses theoret- ical perspectives that contextualize animal agency in terms of relationships and then looks at those relationships from an ethological perspective. This provides a sense of what the dogs did that distinguishes between how humans understand dogs and what we know about dogs’ cognitive and social capacities. The paper proposes a model of animal agency that looks seriously at the dogs’ relationships with human researchers and suggests that the dogs’ significance as historical subjects depends as much on what they did as dogs as it does on how their contributions to the space race were perceived. Among the legions of animals used in scientific research few have garnered the fame of the Soviet space dogs.
