Laika Dog and the Early Days of Space Exploration

Laika, the Soviet space dog, was a brave little pup who paved the way for human space exploration. Launched on November 3, 1957, Laika became the first living creature to orbit the Earth.

Laika was a stray dog that was found on the streets of Moscow. She was chosen for the Sputnik 2 mission due to her small size and calm temperament. Laika was about 11 pounds and had a short, fluffy coat.

Laika's journey to space was a historic moment in space exploration. She was placed in a specially designed capsule that was attached to the Sputnik 2 rocket. Laika's mission was to test the safety of space travel for living organisms.

Laika's mission was a significant one, and it was launched just a month after Sputnik 1. The project was rushed to coincide with the anniversary of the Bolshevik revolution.

The spacecraft, Sputnik 2, was much larger and more elaborate than its predecessor. It stood 13 feet tall and 6.5 feet wide.

Sputnik 2 weighed a substantial 1,120 pounds. The spacecraft carried scientific instruments to measure solar radiation and cosmic rays.

Laika's cabin was equipped with an air regeneration system and padding. She could sit or lie down in the cabin.

Laika had a harness, a crude sanitation device, and a set of electrodes. She had access to food and water in a gelatinized form.

The early telemetry indicated that Laika was agitated but eating her food.

Laika was a black-and-white mutt originally named Kudrayavka, or Little Curly, who weighed about 13 pounds (6 kilograms) at the time of her flight.

Laika's launch pad to fame were the streets of Moscow, where Soviet rocket scientists collected stray dogs to better understand what launch, microgravity and other aspects of spaceflight might do to a human body.

The researchers selected the most obedient and those most tolerant of loud noises and air pressure changes, and subjected final candidates to test runs in small capsules – some lasting for weeks.

Laika's later name, which means Barker, came about when she barked during a radio interview.

Laika weighed about 13 pounds (6 kilograms) at the time of her flight, according to NASA. She was a small but significant part of a larger project.

The Soviet rocket scientists wanted to send dogs to space to better understand what launch, microgravity and other aspects of spaceflight might do to a human body. They collected stray dogs from the streets of Moscow.

The contenders had to be female (easier to rig up) and brightly colored (so video footage of them would be clearer).

Laika was chosen from a small group of stray female dogs gathered from the streets of Russia.

The Soviet recruiters tested the dogs for obedience, reactions to changes in air pressure, and loud noises, narrowing it down to just two potential choices.

Doctors performed gruesome surgery on both dogs, embedding medical devices into their bodies to monitor heart impulses, breathing rates, physical movement, and blood pressure.

Laika was chosen because of her docile and submissive nature.

She later became known as Laika after barking repeatedly on the radio when introduced to the public.

The decision to choose Laika was likely influenced by her calm temperament, which made her a more suitable candidate for the mission.

Laika's story is a tragic reminder of the risks and consequences of space travel.

Laika, a Soviet space dog, was launched into space on November 3, 1957, aboard Sputnik 2, a satellite not designed to return to Earth safely.

The Soviet space program didn't want to delay the launch, so Laika's death was essentially a suicide mission.

Laika survived the launch, but telemetry data showed that she died when the cabin overheated, likely due to a faulty thermal control system and torn insulation.

This overheating occurred either 4 days into the mission, 5 or 6 hours into the mission, or even earlier, depending on the source.

The spacecraft continued to orbit the Earth until April 14, 1958, when it re-entered the atmosphere after 2,570 orbits.

Many people reportedly saw a fiery trail of Sputnik 2 as it flew over New York and the Amazon region during its re-entry.

The ethics of animal testing in space were largely unaddressed at the time, overshadowed by the Soviet-U.S. Space Race.

The National Canine Defence League in the UK called for a minute's silence on each day Laika remained in space, while the Royal Society for the Prevention of Cruelty to Animals received protests.

In the Soviet Union, there was less controversy, but Oleg Gazenko, one of the scientists responsible for sending Laika into space, later expressed regret for allowing her to die, saying "we shouldn't have done it."

The mission sparked a debate across the globe on the mistreatment of animals and animal testing in general to advance science.

Laika's story wasn't an isolated incident - many animals were sent to space during the 20th century.

The first mammal in space was a rhesus monkey named Albert II, who died on landing due to a defective parachute in 1949.

The US launched Enos the chimpanzee into space in 1961, who died due to a technical malfunction subjecting him to 76 electric shocks.

These incidents raised serious ethical concerns about the use of animals in space travel.

Laika was found as a stray wandering the streets of Moscow, and Soviet scientists chose her because they assumed she had already learned to endure extreme cold and hunger.

She was a 5 kg (11 lb) mongrel female, approximately three years old, and was given several names and nicknames, including Kudryavka, Zhuchka, and Limonchik.

Laika was trained to endure the conditions of space by being kept in progressively smaller cages for up to twenty days, which caused her to stop urinating or defecating, and made her restless.

The researchers found that only long periods of training proved effective, and the dogs were placed in centrifuges that simulated the acceleration of a rocket launch and machines that simulated the noises of the spacecraft.

Laika was trained to eat a special high-nutrition gel that would be her food in space, and her pulse doubled and blood pressure increased by 30–65 torrs (4.0–8.7 kPa) during the simulated launch.

Ten days before the launch, Vladimir Yazdovsky chose Laika to be the primary flight dog, and before the launch, he took her home to play with his children.

Laika was placed in the capsule of the satellite on 31 October 1957, three days before the start of the mission, and a hose connected to a heater was used to keep her container warm due to the extremely low temperatures at the launch site.

Two assistants were assigned to keep a constant watch on Laika before launch, and just prior to liftoff, her fur was sponged in a weak ethanol solution and carefully groomed, while iodine was painted onto the areas where sensors would be placed to monitor her bodily functions.

Laika's respiration increased to between three and four times the pre-launch rate at peak acceleration. Her heart rate was 103 beats/min before launch and increased to 240 beats/min during the early acceleration.

After reaching orbit, the "Block A" core did not separate as planned, preventing the thermal control system from operating correctly. Some of the thermal insulation tore loose, raising the cabin temperature to 40 °C (104 °F).

Laika's pulse rate had settled back to 102 beats/min after three hours of weightlessness, three times longer than it had taken during earlier ground tests, an indication of the stress she was under.

The sensors showed her heart rate was 103 beats/min before launch.

Laika's heart rate increased to 240 beats/min during the early acceleration.

After reaching orbit, Sputnik2's nose cone was jettisoned successfully.

However, the "Block A" core did not separate as planned, preventing the thermal control system from operating correctly.

Some of the thermal insulation tore loose, raising the cabin temperature to 40 °C (104 °F).

Laika's pulse rate had settled back to 102 beats/min after three hours of weightlessness.

It took Laika three times longer than it had during earlier ground tests to settle back into a normal pulse rate.

The early telemetry indicated that Laika was agitated but eating her food.

After approximately five to seven hours into the flight, no further signs of life were received from the spacecraft.

Laika's remains were still on board Sputnik2 when it disintegrated during re-entry on 14 April 1958.

The spacecraft completed 2,570 orbits before disintegrating.

The orbital flights of the Space Dogs were a remarkable achievement in space exploration. These dogs were the first Earth-born creatures to go into orbit and return alive.

Belka and Strelka were the first to accomplish this feat on August 19, 1960, aboard Korabl-Sputnik-2. They spent a day in space with a grey rabbit, 42 mice, 2 rats, flies, and several plants and fungi, and all survived.

Their flight was a significant milestone in space exploration, and it paved the way for future orbital flights. These dogs were not only pioneers in space travel but also helped to lay the groundwork for human spaceflight.

Here are some key facts about the orbital flights of the Space Dogs:

The orbital flights of the Space Dogs were a testament to the ingenuity and determination of the Soviet space program. These dogs played a crucial role in the development of space exploration, and their legacy continues to inspire new generations of scientists and engineers.

Laika's legacy is a testament to her pioneering spirit. She was memorialized in the form of a statue and plaque at Star City, the Russian Cosmonaut training facility, created in 1997.

Laika is also honored at the Monument to the Conquerors of Space in Moscow, constructed in 1964. This monument is a significant tribute to her role in space exploration.

A monument of Laika was unveiled on 11 April 2008 at the military research facility where she was prepared for her flight. It features her poised on top of a space rocket.

Laika's image has been used on various souvenirs, including stamps, envelopes, cigarettes, and matches.

Laika, the Soviet space dog, was launched on November 3, 1957, aboard Sputnik 2, a spacecraft designed to test the safety of space travel for living organisms.

Laika was a stray dog from Moscow's streets, weighing around 11 pounds and measuring 16 inches in length.

The Soviet Union chose Laika for the mission due to her small size and calm temperament, making her an ideal candidate for space travel.

Laika's mission was to test the safety of space travel for living organisms, and she became the first animal to orbit the Earth.

Laika's spaceflight lasted about five hours, during which she experienced temperatures ranging from -18°C to 40°C.

Laika's fate was sealed from the start, as the technology at the time did not allow for her to be safely returned to Earth.
