What’s the explanation behind the numerous deceased animals drifting through space?

On July 20, 1969, Neil Armstrong made history as the first human to walk on the moon's surface. Millions across the globe watched the broadcast, and after Edwin 'Buzz' Aldrin Jr. joined him, the pair spent roughly two and a half hours collecting lunar rocks to bring back for scientific analysis. This monumental achievement marked not only a victory for the United States but for humanity as a whole.

However, what many don’t realize are the immense sacrifices made to send humans into space. The true unsung heroes of space exploration, it turns out, are the animals. Let's explore the history of animal astronauts and understand why so many of them perished in the vastness of space.

The First Creatures to Embark on Space Journeys

Before humans could even dream of space travel, scientists struggled to predict how a living organism would fare outside of Earth's atmosphere. What would weightlessness or space motion sickness do to a mammal? How would the human body respond to radiation from the sun? To understand these potential risks, both the United States and Russia sent monkeys, chimpanzees, dogs, and other animals into space to study these effects before risking human lives.

Unfortunately, given the early stage of the space race, vehicle designs were still in their experimental phases. With faulty launches or reentry procedures, the survival chances for the animals aboard were slim. In some instances, Soviet spacecraft carrying dogs and guinea pigs were lost in space, leading to speculation that there are still abandoned vessels orbiting Earth, holding their original furry passengers.

First Animals in Space Exploration

The first living beings to successfully journey into space and return were surprisingly smaller than a monkey or a dog. In 1947, a container filled with fruit flies was launched 106 miles above Earth and parachuted safely back with no visible harm.

Following that achievement, larger animals began to be sent into space. In 1948, the Aero Medical Laboratory started conducting animal experiments in White Sands, N.M. On June 11, a V-2 Blossom rocket carried Albert I, a rhesus monkey, into space. Unfortunately, due to the cramped conditions, Albert suffocated during the flight. The name 'Albert' became a tradition, with every subsequent rhesus monkey or simian in the program named Albert, leading to what’s now known as the Albert Project.

Sadly, the Albert Project was marked by repeated failures, with most missions suffering technical malfunctions and fatal injuries. However, the second monkey, Albert II, made it through the entirety of his spaceflight, only to die upon reentry when the capsule’s parachute malfunctioned.

The First Dogs to Enter Space

As the 1950s progressed, more missions led to greater advancements, but the most iconic space animal remains Laika. Just a month after the Soviet Union amazed the world with the launch of Sputnik I, the first satellite to orbit Earth, they revealed an even more shocking development. On November 3, 1957, Sputnik 2 launched with Laika, a dog, aboard. Laika, originally named Kudryavka (or 'Little Curly') by her trainers, was a 13-pound, part-Samoyed mongrel found on the streets of Russia. Stray dogs were favored for space missions due to their resilience and ability to endure cold temperatures.

The media frenzy surrounding Sputnik I pushed Nikita Khrushchev, leader of the Communist Party, to rush the launch of Sputnik 2 to coincide with the one-month 'anniversary' of Sputnik I. Unfortunately, the design of the new space shuttle was inadequate. The Soviets even admitted shortly after the launch that Laika would not be returning, and the satellite itself burned up during reentry.

Authorities initially claimed Laika survived in orbit for up to four days before succumbing to overheating. However, in 2002, it was revealed that Laika actually died just a few hours after launch due to a combination of heat and panic. Her tragic death sparked discussions in America about animal rights, while in Russia, Sputnik 2 was seen as a regrettable attempt at propaganda.

A Moral Dilemma: The Fate of Animals in Space

Every major space agency that has achieved significant success has reached a milestone in animal experimentation. From stick insect eggs to chimpanzee spaceflights, numerous animal species have now ventured beyond Earth's atmosphere.

It seems that experiments involving animals in space aren't going to stop anytime soon. Just as recently as June 2021, SpaceX sent water bears and baby squids to the International Space Station, a place that has hosted all kinds of species over the years, from reptiles to quails. Whether animal enthusiasts approve or not, it looks like animals still have a place — albeit uncertain — in outer space.
