PS 2 (Prostreishiy Sputnik 2), better known as Sputnik 2, was the world's second artificial satellite and the first to carry an animal into orbit.. PS 2 was one of the two simple payloads to be orbited before the more complex D-1 satellite was ready. By the fourth orbit none of the physiological sensors were returning data -- Laika had evidently died.

Once he was done, he was careless enough to jump from the erector onto the concrete floor five meters below, instead of "wasting time," walking down the narrow stairs. Laika, a dog that was the first living creature to be launched into Earth orbit, on board the Soviet artificial satellite Sputnik 2, on November 3, 1957.

Laika was a stray dog found on the streets of Moscow. "Myths and reality about Laika's mission at a glance:The author of this page will appreciate comments, corrections and imagery related to the subject. Laika was chained in place and fitted with a The mission provided scientists with the first data on the behavior of a living organism in the space environment.The time after Sputnik 2 was tense for the Americans and exciting for the Soviets. "The second satellite was created without preliminary design, or any kind of design." (After a series of rocket engine tests, aimed to select the powerplants with highest performance characteristics, For the mission, military doctors selected three out of 10 available dogs: Laika (as a "flight dog"); Albina (a backup, who previously made two ballistic flights on A brand-new Tupolev-104 jet aircraft was chartered to transport dogs and key personnel, participating in the mission. Sputnik 2, launched on November 3, 1957, carried the dog Laika, the first living creature to be shot into space and orbit Earth. The interstage section between the booster and capsule was highly polished and equipped with thermal blankets so as to reflect off sunlight and keep the latter cool; also, several deployable reflectors were mounted on the core stage. It was launched on 3 October 1957 at Baikonur Cosmodrome. Sputnik 2 was a Soviet Union spacecraft.It was the second spacecraft in the Sputnik programme.It was the first spacecraft to carry a living animal, a dog called Laika.

Problems had to be urgently corrected. was issued on March 17, 1958. Albina was the back-up dog, and had survived earlier sounding rocket flights into space. After the launch, Soviet space officials said that the spacecraft would not return and that the dog had enough food and oxygen to live for up to 10 days. Since it was very late in the pre-launch processing, Shumakov had to climb the rocket already resting on its movable erector to do re-wiring of his circuit. It was a cold night, and while personnel was finalizing launch preparations, technicians extended a hose from the ground air-conditioning unit toward the cabin to warm up the dog.As remembered by Yevgeniy Shabarov, "after placing Laika in the container and before closing the hatch, we kissed her nose and wished her bon voyage, knowing that she would not survive the flight." allowed her movements in the cabin to be seen. Provocations #36: The Van Allen radiation belts almost scooped | OpenSky Repository. They launched Sputnik 2 on Nov. 3, 1957, carrying a dog, named Laika, on board. According to Chertok's memoirs, most elements of the spacecraft were manufactured from sketches, while engineers moved into production facilities to assist workers on site. Laika was sealed into her cramped cabin four days before launch. These included modifying the launch trajectory to utilize propellant more efficiently and removing some flight control components to reduce weight. Reentry was sighted from the east coast of the United States and surviving debris impacted in the Amazon region of South America.The flight sparked considerable ethical debate about cruelty to animals, as Laika had been launched with the full knowledge that she could not be recovered and may have suffered a quite unpleasant death from panic and overheating, and even some Soviet space program officials reportedly felt sorry about her. The satellite burned up in the atmosphere.A USSR-built engineering model of the R-7 Sputnik 8K71PS (Sputnik II) is located at the Cox, Donald & Stoiko, Michael, "Spacepower what it means to you", Philadelphia, Pennsylvania, The John C.

The world's first artificial satellite was about the size of a beach ball (58 cm.or 22.8 inches in diameter), weighed only 83.6 kg. "The second satellite was created without preliminary design, or any kind of design." Overall, however, the dog survived the launch unscathed. Sputnik 2 reentered the atmosphere on 14 April 1958 after 162 days in space and about 2500 orbits. As telemetry later revealed Laika's heart was beating 260 cycles per minute, or three times higher than normal during the ride to orbit. By then, the Soviets had already achieved another ideological victory when they launched a dog into orbit aboard Sputnik 2… Estimates put the average length of the tail at about 50 nautical miles (93 km; 58 mi).

It stated that although "available evidence does not permit a positive determination that this satellite in fact did carry an animal," the agency officials "believe that SPUTNIK II did carry a live dog. "All traditions developed in rocket technology were thrown out (during work on the second satellite)," wrote Boris Chertok, deputy to Sergei Korolev. Catalog numbers, years of issue, and notes on the satellites featured are given when available.
