Ilustracija u znak sećanja na Lajku, Renia Metallinou

Lajka nije bila sasvim običan pas. Bilo je to malo stvorenje teško svega šest kilograma, mešanka haskija i terijera sa moskovskih ulica, navikla na hladnoću i ekstremne uslove. Ujedno prvi živi sisar poslat u Zemljinu orbitu i prva orbitalna žrtva. Kada je lansirana u svemir znalo se unapred da se Lajka neće vratiti i da će njeno pseće srce zauvek ostati da kuca negde gore, među zvezdama. Još jedan primer ljudske bezosećajnosti. Iako Lajka nije preživela, misija „Sputnjika 2“ je pokazala da živi stvor može da izdrži lansiranje u orbitu i bestežinsko stanje. I još jednom pokazala da je nauka važnija od života jednog bića. Naravno, njena žrtva sa te strane nije bila uzaludna. Stradala je za "dobrobit čovečanstva" omogućila Belki i Strelki, opet psi, da se iz orbite vrate žive i zdrave i utrla put Gagarinu, Leonovu, Titovu, Armstrongu, Oldrinu i nizu kosmonauta koji su se kasnije našli na Međunarodnim svemirskim stanicama.

Laika was a Soviet space dog who became one of the first animals in space, and the first animal to orbit the Earth. Laika, a stray mongrel from the streets of Moscow, was selected to be the occupant of the Soviet spacecraft Sputnik 2 that was launched into outer space on 3 November 1957.Little was known about the impact of spaceflight on living creatures at the time of Laika's mission, and the technology to de-orbit had not yet been developed, so Laika's survival was never expected. Some scientists believed humans would be unable to survive the launch or the conditions of outer space, so engineers viewed flights by animals as a necessary precursor to human missions.The experiment aimed to prove that a living passenger could survive being launched into orbit and endure a micro-g environment, paving the way for human spaceflight and providing scientists with some of the first data on how living organisms react to spaceflight environments.

Laika died within hours from overheating, possibly caused by a failure of the central R-7 sustainer to separate from the payload. The true cause and time of her death were not made public until 2002; instead, it was widely reported that she died when her oxygen ran out on day six or, as the Soviet government initially claimed, she was euthanised prior to oxygen depletion.

On 11 April 2008, Russian officials unveiled a monument to Laika. A small monument in her honour was built near the military research facility in Moscow that prepared Laika's flight to space. It portrayed a dog standing on top of a rocket. She also appears on the Monument to the Conquerors of Space in Moscow.

The Sad, sad story of Laika, the Space Dog, and Her One-Way Trip into Orbit a stray Moscow pup traveled into orbit in 1957 with one meal and only a seven-day oxygen supply. Sad as this tale is, the stray husky-spitz mix became a part of history as the first living creature to orbit the Earth.

Tuzno ja nikad nebi koristila zivotinje u tim eksperimentima, ko zna kakvu je agoniju i muke prezivela kad je krenula da se gusi i umire, tamo gore negde sama,

Uvek sam bila protiv da se neciji zivot koristi za dobrobit nauke..Lajka je bila neko ko nije imao pravo glasa, koja je dozivela tesku smrt. Svaki zivot je vazan pa i pseci... Nisam za te eksperimente na zivotinjama, neka se ljudi malo uozbilje, i ne izmisljaju razne bolesti itd...Hocemo mi na mesec..Pa ni zemlju ne umemo da cuvamo, a hocemo na mesec....

The Soviet Union stunned the world on Nov. 3, 1957, with the launch of Sputnik 2. On board the small satellite was a little dog, Laika, the first animal to orbit Earth. However, Laika was not the first animal in space. The United States and the U.S.S.R. had been putting animals atop rockets since 1947.

In the early days of rocket science, no one knew what the effects of weightlessness would be. Animals — mainly dogs, monkeys and chimps — were used to test the safety and feasibility of launching a living being into space and bringing it back unharmed.

Since then, animals have continued to play an important role in understanding the impact of microgravity on many biological functions. Astronauts have studied all kinds of animals — wasps, beetles, tortoises, flies, worms, fish, spiders, rabbits, bees, ants, frogs, mice, crickets, rats, newts, snails, urchins, moths, brine shrimp, jellyfish, guinea pigs, butterflies, scorpions and Laika was a young, mostly-Siberian husky. She was rescued from the streets of Moscow. Soviet scientists assumed that a stray dog would have already learned to endure harsh conditions of hunger and cold temperatures. Laika and two other dogs were trained for space travel by being kept in small cages and learning to eat a nutritious gel that would be their food in space. The dog's name was originally Kudryavka, or Little Curly, but she became known internationally as Laika, a Russian word for several breeds of dog similar to a husky. American reporters dubbed her Muttnik as a pun on Sputnik.

Unfortunately, Laika's trip into space was one-way only. A re-entry strategy could not be worked out in time for the launch. It is unknown exactly how long Laika lived in orbit — perhaps a few hours or a few days — until the power to her life-support system gave out. Sputnik 2 burned up in the upper atmosphere in April 1958. Although there is no distinct boundary between the atmosphere and space, an imaginary line about 68 miles (110 kilometers) from the surface, called the Karman line, is usually where scientists say Earth's atmosphere meets outer space.

The first animals to reach space — not counting any bacteria that may have hitched a ride on previous rockets — were fruit flies. On Feb. 20, 1947, the United States put fruit flies aboard captured German V-2 rockets to study radiation exposure at high altitudes. In 3 minutes and 10 seconds, the fruit flies reached a distance of 68 miles. The first mammal in space was Albert II, a Rhesus monkey. Albert I's mission had been unsuccessful, but the second Albert reached a distance of 83 miles on June 14, 1949. Albert was anesthetized during flight and implanted with sensors to measure his vital signs. Unfortunately, Albert II died upon impact at re-entry.

While the United States was experimenting with monkeys, the Soviet Union was experimenting with dogs. During the 1950s and 1960s, the Soviet Union had slots for at least 57 dogs. However, because some dogs flew more than once, fewer than 57 actually participated.

The first dogs launched, Tsygan and Dezik, were aboard the R-1 IIIA-1. The dogs reached space on July 22, 1951, but did not orbit. They were the first mammals successfully recovered from spaceflight.

After Laika, the Soviet Union sent two more dogs, Belka and Strelka, into space on Aug. 19, 1960. The animals were the first to actually orbit and return alive.

na zalost, kao sto rece bata bane, svaki napredak zahteva odredjene zrtve, danas nismo ni svesni koliko smo dobili time sto smo koristili a i dalje koristimo zivotinje u cilju ljudske dobrobiti, lajka je samo simbol svih ti zivotinja cija patnja nam danas omogucava bolji zivot

It's too cruel that human make use of animals' life for experiment. Animals have the right to live in the world.

Ona je o tome dobila pismo američke svemirske agencije koje joj je uručio ambasador SAD u Bosni i Hercegovini, Eric Nelson, objavila je agencija Srna.

Pretpostavlja se da je živjela koliko je imala kisika u kapsuli, iako neki tvrde da je 3. studenog 1957. uginula odmah od previsoke temperature, a neki da je uginula pojevši otrov u posljednjem predviđenom obroku.
