Laika... ?

Answer 1

Laika (from Russian: Лайка, a breed of dog, literally: "Barker") was a Russian space dog which became the first living creature from Earth to enter orbit. At one time a stray wandering the streets of Moscow, she was selected from an animal shelter. Originally named Kudryavka (Russian: кудрявка), she was renamed Laika after her breed type. After undergoing training with two other dogs, she was selected to be the occupant of the Soviet spacecraft Sputnik 2 and was launched into space on 3 November 1957.

Laika died a few hours after launch from stress and overheating, probably due to a malfunction in the thermal control system. The true cause of her death was not made public until decades after the flight. Some former Soviet scientists have since expressed regret that Laika was allowed to die.

Although Laika did not survive the trip, the experiment proved that a living passenger could survive being launched into orbit and endure weightlessness. It paved the way for human spaceflight and provided scientists with some of the first data on how living organisms react to spaceflight environments.

Sputnik 2

A model of Sputnik 2, Laika's space vehicleMain article: Sputnik 2
After the success of Sputnik 1, Nikita Khrushchev, the Soviet leader, wanted a second spacecraft launched on November 7, the 40th anniversary of the Bolshevik Revolution. A more sophisticated satellite was already under construction, but it would not be ready until December; this satellite would later become Sputnik 3.

To meet the November deadline, a new, less sophisticated design had to be built. According to Russian sources, the official decision to launch Sputnik 2 was made on October 10 or 12, leaving the team only four weeks to design and build the space craft. Sputnik 2, therefore, was something of a rush job, with most elements of the space craft being constructed from rough sketches. Aside from the primary mission of sending a living passenger into space, Sputnik 2 also contained instrumentation for measuring solar radiation and cosmic rays.

The craft was equipped with a life-support system consisting of an O2 generator and devices to avoid oxygen poisoning and to absorb CO2. A fan, designed to activate whenever the cabin temperature exceeded 15 °C (59 °F), was added to keep the dog cool. Enough food (in a gelatinous form) was provided for a seven-day flight, and the dog was fitted with a bag to collect waste. A harness was designed to be fitted to the dog, and there were chains to restrict its movements to standing, sitting or lying down; there was no room to turn around in the cabin. An electrocardiogram monitored heart rate and further instrumention tracked respiration rate, maximum arterial pressure and the dog's movements.


Training and voyage
The dog that would later be named Laika was found as a stray wandering the streets of Moscow. She was a mongrel female, approximately three years old, and weighed about 6 kg (13 lb). Soviet personnel gave her several names and nicknames, 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 popularized around the world. The American press dubbed her Muttnik (mutt + suffix -nik) as a pun on Sputnik,[6] or referred to her as Curly.[7] Her true pedigree is unknown, although it is generally accepted that she was part husky or other Nordic breed, and possibly part terrier.[8]

The Soviet Union and the United States had previously sent animals only on sub-orbital flights.[9] Three dogs were trained for the Sputnik 2 flight: Albina, Mushka, and Laika.[10] Russian space-life scientist Oleg Gazenko selected and trained Laika.[11] Albina flew twice on a high-altitude test rocket, and Mushka was used to test instrumentation and life support.[5][9] To adapt the dogs to the confines of the tiny cabin of Sputnik 2, they were kept in progressively smaller cages for periods 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.[5]

According to a NASA document, Laika was placed in the satellite on October 31, 1957—three days before the start of the mission.[5] The temperatures at the launch site were extremely cold at that time of year, so a hose connected to a heater was used to keep her container warm. Two assistants were assigned to keep a constant watch on Laika before launch. Just prior to liftoff on November 3, 1957 from Baikonur Cosmodrome, Laika's fur was sponged in a weak alcohol solution and carefully groomed. Iodine was painted onto areas where sensors would be placed to monitor her bodily functions.[12]

At peak acceleration Laika's respiration increased to between three and four times the pre-launch rate.[5] The sensors showed her heart rate was 103 beats/min before launch and increased to 240 beats/min during the early acceleration. After reaching orbit, Sputnik 2'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).[13] After three hours of weightlessness, Laika's pulse rate had settled back to 102 beats/min,[14] three times longer than it had taken during earlier ground tests, an indication of the stress she was under. The early telemetry indicated that Laika was agitated but eating her food.[13] Approximately five to seven hours into the flight, no further life signs were received from the spacecraft.[5]

The Russian scientists had planned to euthanize Laika with a poisoned serving of food. For many years, the Soviet Union gave conflicting statements that she had died either from oxygen starvation when the batteries failed, or that she had been euthanized. There were many rumours circulated about the exact manner of her passing. In 1999, several Russian sources said that she died after four days when the cabin overheated.[3] In October 2002, Dr. Dimitri Malashenkov, one of the scientists behind the Sputnik 2 mission, revealed that Laika had died five to seven hours after launch from overheating and stress. According to a paper he presented to the World Space Congress in Houston, Texas, "It turned out that it was practically impossible to create a reliable temperature control system in such limited time constraints."[4] Sputnik 2 was finally destroyed (along with Laika's remains) during re-entry on April 14, 1958, just over 5 months later, after 2,570 orbits.[15]


Controversy
Due to the overshadowing issue of the Soviet vs. American Space Race, the humane violations of this experiment went largely unaddressed for some time. As newspaper clippings from 1957 show,[1] the press was more preoccupied with reporting the political perspective, while the health and retrieval (or lack thereof) of Laika was hardly mentioned. Only later were there widespread discussions regarding the fate of the dog.

Sputnik 2 was not designed to be retrievable, so Laika had always been intended to die.[3] The mission sparked a debate across the globe on the mistreatment of animals and animal testing in general to advance science.[11]

In the United Kingdom, the National Canine Defence League called on all dog owners to observe a minute's silence, while the Royal Society for the Prevention of Cruelty to Animals (RSPCA) received protests even before the Soviet Union had finished announcing the mission's success. Animal rights groups at the time called on members of the public to protest at Soviet embassies.[16] Others demonstrated outside the United Nations in New York;[11] nevertheless, laboratory researchers in the U.S. offered some support for the Russians, at least before the news of Laika's death.[11][17]

In the Soviet Union, there was apparently less controversy. Neither the media, books in the following years, nor the public openly questioned the decision to send a dog into space to die. It was not until 1998, after the collapse of the Soviet regime, that Oleg Gazenko, one of the scientists responsible for sending Laika into space, expressed regret for allowing her to die: "The more time passes, the more I'm sorry about it. We shouldn't have done it... We did not learn enough from this mission to justify the death of the dog."

Answer 2

Yes, the first living being from the planet earth to enter space. What about her?

To the others - a 20-second search on Google produced the following facts:

Laika died a few hours after launch from stress and overheating, probably due to a malfunction in the thermal control system. The true cause of her death was not made public until decades after the flight. In October of 2002, during a gathering of the World Space Congress in Houston, Texas, it was revealed by Dr. Dimitri Malashenkov of the Institute for Biological Problems in Moscow, that after five to seven hours following the launch of Sputnik-2, no lifesigns were being received from Laika.

Answer 3

First dog to orbit the Earth, sent up on Sputnik 2 in late 1957 or early 1958 (can't recall which right now). Died in orbit by a poisoned last meal, but would have died anyway because sputnik 2 had no heatshield, and hence no way to bring Laika back to Earth.

Answer 4

This is the second time this hour I've answered the same question.
Coincidence?
Same school?
Laika was a dog (name meaning 'Barker') that was launched by the (then) Soviet Union.
She was placed aboard a rocket to see if the physical strains of spaceflight would be too much for a human body to bear.
Sadly, she didn't survive, she would have died, anyway...
She was meant to die.

Answer 5

Russian dog on board the Sputnik satellite. First living thing in orbit.
Insiders claim the dog died hours into the trip, but the Russians maintained that the dog lived for several days.
