Laika: The Stray Who Became the First Animal to Orbit Earth
Laika didn’t volunteer for the space program, and she didn’t come home from it. Her flight is one of the most consequential — and most quietly tragic — stories in the history of spaceflight.
From Moscow stray to cosmonaut
Soviet engineers, working under a tight deadline set by Premier Nikita Khrushchev to launch before the 40th anniversary of the Bolshevik Revolution, recruited stray dogs from the streets of Moscow because they judged strays hardier than pets. The dog originally named Kudryavka (“Little Curly”) was renamed Laika — “Barker” — after she barked during a radio interview. Sputnik 2 was built with no way to bring her back.
The truth the world wasn’t told
Soviet sources claimed for years that Laika survived multiple days in orbit. In October 2002, Russian scientist Dimitri Malashenkov revealed the real outcome: Sputnik 2’s cabin overheated, and Laika died within five to seven hours of launch from heat and panic. The revelation renewed a global debate over animal testing; Oleg Gazenko, a scientist who worked on the program, later said he regretted the flight.
Her memorial
On April 11, 2008, officials unveiled a monument to Laika near the Moscow military research facility that had prepared her for flight — a two-meter sculpture by Pavel Medvedev showing a rocket transitioning into an open hand, with Laika standing on top.
Laika’s story sits alongside the rest of history’s dogs who paid a real price for their fame in our hero dogs guide.
Frequently asked questions
Was Laika the first animal in space?
No — several other animals had already reached space on earlier suborbital flights. Laika was the first animal to orbit the Earth, launched aboard Sputnik 2 on November 3, 1957.
How long did Laika actually survive in orbit?
For decades the Soviet Union claimed she lived for days. Declassified in 2002, records showed she died within five to seven hours of launch when Sputnik 2’s cabin overheated.
Is there a memorial to Laika?
Yes — a monument near the Moscow military facility that prepared her for flight was unveiled on April 11, 2008, showing Laika standing atop a rocket transitioning into an open hand.
