Lika, sent by then USSR

Answer 10

Laika. She was a mongrel, part Siberian husky, a 3-year-old stray found on the streets of Moscow.

Laika (from Russian: Лайка, "Barker") was a Russian space dog that became the first living creature from Earth to enter orbit. She was found as a stray wandering the streets of Moscow. Originally named Kudryavka, 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 November 3, 1957.

Laika died a few hours after launch from stress and overheating. 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

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 4 weeks to design and build the space craft. Sputnik 2, therefore, was something of a rushed 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, as well a fan designed to activate whenever the cabin temperature exceeded 15 °C (59 °F) in order to keep the dog cool. Enough food (in a gelatinous form) was provided for a 7-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 keep it from moving except for 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.

After reaching orbit the nose cone was jettisoned successfully but the "Blok A" core did not separate as planned, preventing the thermal control system from operating correctly. Some of the thermal insulation also tore loose. Consequently, the temperature in the cabin rose to 40 °C (104 °F).

Training and voyage

Laika was found as a stray wandering the streets of Moscow; a mongrel female, approximately three years old, weighing about 6 kg (13 lb). "Laika" is the Russian name for several breeds of dogs similar to the husky. Her name was changed from Kudryavka (Russian for "Little Curly"), and she was also nicknamed Zhuchka ("Little Bug") and Limonchik ("Little Lemon").

The American press dubbed her Muttnik (mutt + suffix "-nik") as a pun on Sputnik, the Russian satellite program,[6] and she was also referred to as Curly.[7] Her true ancestry can never be known, although it is generally accepted that she was part husky or other Nordic breed, and possibly part terrier.

The Soviet Union and the United States had previously sent animals only on sub-orbital flights. Three dogs were trained for the Sputnik 2 flight: Albina, Mushka, and Laika. Laika was selected and trained by the Russian space-life scientist Oleg Gazenko. Albina flew twice on a high-altitude test rocket while Mushka was used to test instrumentation and life support.

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 15 to 20 days. The extensive close confinement caused them to stop urinating or defecating, making them restless, and causing 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 also placed in centrifuges that simulated the acceleration of a rocket launch and were placed in simulators that simulated the noises of the spacecraft. This would cause 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.

According to a NASA document, Laika was placed in the satellite on October 31, 1957—three days before the start of the mission. 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 launch on November 3, 1957 from Baikonur Cosmodrome, Laika's fur was sponged in a weak alcohol solution, and then carefully groomed. Iodine was painted onto areas where sensors would be placed to monitor her bodily functions.

At peak acceleration Laika's respiration increased to between 3 and 4 times the pre-launch rate. The sensors showed her heart rate was 103 beats/min before launch and increased to 240 beats/min during the early acceleration. After 3 hours of weightlessness, it had settled back to 102 beats/min, but this was three times longer than it had taken during earlier ground tests, an indication of stress.

The early telemetry indicated that Laika was agitated but eating her food. Approximately five to seven hours into the flight, no further life signs were received from the spacecraft.

It had been planned that Laika would be euthanized with a poisoned serving of food after 10 days. For many years, the Soviet Union gave conflicting statements that she had either died 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. In October 2002, it was revealed by Dr. Dimitri Malashenkov, one of the scientists behind the Sputnik 2 mission, that Laika had died between five and seven hours after launch, from overheating and stress.

According to a paper he presented to the World Space Congress in Houston, Texas, "It was practically impossible to create a reliable system of a temperature control in such small [sic] term". Sputnik 2 was finally destroyed during re-entry on April 14, 1958, after 2,570 orbits
