【Space Dog】

Laika ( c. 1954 – 3 November 1957) was a Soviet space dog

 

who was one of the first animals in space and the first to orbit the Earth.

 

A stray mongrel from the streets of Moscow, she flew aboard the Sputnik 2 spacecraft, launched into low orbit on 3 November 1957.

 

As the technology to re-enter the atmosphere had not yet been developed, Laika's survival was never expected.

 

She died of hyperthermia hours into the flight, on the craft's fourth orbit.

 

Little was known about the effects of spaceflight on living creatures at the time of Laika's mission,

 

and animal flights were viewed by engineers as a necessary precursor to human missions.

 

The experiment, which monitored Laika's vital signs, aimed to prove that a living organism could survive being launched into orbit

 

and continue to function under conditions of weakened gravity and increased radiation,

 

providing scientists with some of the first data on the biological effects of spaceflight.

 

Laika's death was 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 euthanized prior to oxygen depletion.

 

In 2008, a small monument to Laika depicting her standing atop a rocket was unveiled near the military research facility in Moscow that prepared her flight.

 

She also appears on the Monument to the Conquerors of Space in Moscow.

 

萊卡 (約 1954 年 - 1957 年 11 月 3 日) 是一隻蘇聯太空狗，它是第一批進入太空的動物之一，也是第一隻繞地球運行的動物。

萊卡是一隻來自莫斯科街頭的流浪雜種狗，1957 年 11 月 3 日，它搭乘斯普尼克 2 號太空船進入低軌道。

 

由於當時重返大氣層的技術尚未開發，所以沒有人指望萊卡能夠存活下來。

 

在飛船飛行數小時、繞地球運行第四圈時，她因高熱症死亡。

 

在萊卡執行任務時，人們對太空飛行對生物的影響知之甚少，工程師認為動物飛行是人類任務的必要先決條件。

 

該實驗監測了萊卡的生命體徵，旨在證明生物體被發射到軌道後能夠存活下來，並在重力減弱和輻射增加的條件下繼續正常運作，為科學家提供有關太空飛行生物學影響的一些首批數據。

 

萊卡的死亡可能是由於中央 R-7 支撐裝置無法與有效載荷分離造成的。

 

她的真正死亡原因和時間直到2002年才被公開；相反，廣泛報道稱她在第六天因氧氣耗盡而死亡，或者如蘇聯政府最初聲稱的那樣，她在氧氣耗盡之前就被實施了安樂死。

 

 2008年，在為萊卡準備飛行的莫斯科軍事研究設施附近揭幕了一座小型紀念碑，紀念萊卡，描繪了她站在火箭頂端的場景。

 

她也出現在莫斯科的宇宙征服者紀念碑上。
