Remembering Laika - the first dog that travelled to space 60 years ago
You must be wondering why we are talking about a dog that died 60 years ago on November 3, 1957 and why you should read about it when the world has way more serious stories to discuss.

Well, there is a reason. Laika was no ordinary dog. Laika was the first dog that travelled to space even before the humans. While dogs were launched into outer space before Laika as well, she became the first one to be able to enter low Earth orbit. 

Sixty years ago, Soviet Union put a dog named Liaka aboard Sputnik 2.

The only living creatures that had left for space before Laika were some fruit flies put out in space by the United States.

Laika was put in a satellite weighing more than 500 kgs that had a separate cabin for Liaka, but lacked only one thing: The ability to come back safely; it was designed to leave Earth but not return. As per the Russian space agency, the dog did survive the launch but died after a week in the Earth's orbit due to the cabinet overheating.

But this claim has been contested with some claiming that the overheating occurred just a couple of hours into the mission. While as the Soviet Union had claimed that the dog was euthanised before her death, but a scientist associated with Sputnik 2 revealed that no such thing had taken place and Laika died because of overheating. 

Till April 14, 1958, it kept floating in the space and then landed in the Amazon region. But the efforts did pay off when the Soviet Union launched Yuri Gagarin in an orbital mission. And yes, he was brought back safely to Earth.
