Hello Everyone,
Hope all of you are fine.
Today I've come with an interesting topic.
My huge interest is in Space Science. So I always hunt for these type of Article.
I try to read magazine related to Space.
Okay, let come to the topic.
Do you know, who is the first man who travellled in Space?
You may know it. Yuri Gagarin is the first man who went to space.
But before him one another living thing went to Space. That wasn't any human being. That was a Dog. (Seriously)
A dog went to space first before any human being.
The dog was named Laika.
Little but some major information was known about the impact of spaceflight on living creatures at the time of Laika's mission. The technology of de-orbit hadn't been developed yet so no one would expect the survival of Laika's. As some of scientists claimed that human would be unable to survive the launch of condition of outer space so engineers didn't take any risk. They sent animal to view the impact of Space. The experiment aimed to prove that a living passenger could survive being launched into orbit and endure a micro-g environment, paving the way for human spaceflight and providing scientists with some of the first data on how living organisms react to spaceflight.
The operation has operated by Soviet Union.
Laika was a Russian dog. It was Female.
She was found as a stray wandering the street of Moscow. Soviet scientists chose to use Moscow strays since they assumed that such animals had already learned to endure conditions of extreme cold and hunger.
She was 3 years old (approximately) and weighed about 6 kg (13 lb). She has given severel nick names, among them Kudryavka (Russian for Little Curly), Zhuchka (Little Bug), and Limonchik (Little Lemon). Laika, the Russian name for several breeds of dogs similar to the husky, was the name popularised around the world
Laika was sent to space through the rocket named Sputnik-2. Theree dogs were trained for the flight: Albina, Mushka and Laika. Soviet space-life scientists Vladimir Yazdovsky and Oleg Gazenko trained the dogs.
To adapt the dogs to the confines of the tiny cabin of Sputnik 2, they were kept in progressively smaller cages for periods of up to 20 days. The extensive close confinement caused them to stop urinating or defecating, made them restless, and caused their general condition to deteriorate. Laxatives did not improve their condition, and the researchers found that only long periods of training proved effective. The dogs were placed in centrifuges that simulated the acceleration of a rocket launch and were placed in machines that simulated the noises of the spacecraft. This caused their pulses to double and their blood pressure to increase by 30–65 torr. The dogs were trained to eat a special high-nutrition gel that would be their food in space.
What happened with Laika at last?
Sputnik-2 was launched with Laika on 3 November 1957.
But unfortunately Laika died within hours. She died from overheating, possibly caused by a failure of the central R-7 sustainer to separate from the payload. The true cause and time of her death were not made public until 2002; instead, it was widely reported that she died when her oxygen ran out on day six or, as the Soviet government initially claimed, she was euthanised prior to oxygen depletion.
I was reading about it on Wikipedia and found that info says,
"On 11 April 2008, Russian officials unveiled a monument to Laika. A small monument in her honour was built near the military research facility in Moscow that prepared Laika's flight to space. It portrayed a dog standing on top of a rocket. She also appears on the Monument to the Conquerors of Space in Moscow."
But I didn't find that portrait. (I'm still searching)
As Laika's survival never expected so it wasn't an unexpected matter that she died. But that operation was still success because it gave some major info. It was behind the success of further human journey on Space.
Laika's dedicated life was used to devlop our Space journies.
That's all I know about her. And it was my little try to make you known about it. Hope you enjoyed the post and find something valuable. If yes, then don't forget to Upvote.
