From Sputnik-1 to Sputnik V: Russian scientific achievements

In one of the most significant modern inventions, Russia launched the first artificial satellite on October 4, 1957.

At the time, the beep-beep sent back to Earth from Sputnik-1 represented the start of the space race between the Soviet Union and the United States during the Cold War.

Sent to space by an intercontinental ballistic missile, which forced Washington to realise that Moscow would be able to strike its territory.

The Soviets maintained their lead in the initial years of the race. They boasted the first manned flight to space by Gagarin on April 12, 1961, the first spacewalk four years later by Alexei Leonov and the first lunar probe in 1966.

But the United States beat them to the moon with the first manned landing in 1969.

Ten years before Sputnik, Russia had invented a more nefarious tool: the Kalashnikov assault rifle, also known as the AK-47 and created by Soviet military engineer Mikhail Kalashnikov.

With some 100 million Kalashnikovs currently in circulation, the weapon became ubiquitous globally for its low price and reliability in harsh climates from frozen tundras to dusty Middle Eastern environments.

The weapon also became a symbol of struggles against colonisation and still adorns the flag of Mozambique, representing the struggle for national sovereignty.

Less deadly was Russia's invention of Tetris, though it is just as popular around the world.

The tile-matching video game was thought up in 1984 by software engineer Alexei Pajitnov, whose stated ambition was to make people happy through computers.

Russia also used software to revolutionise an existing game: chess.

The chess powerhouse, which as the Soviet Union held the world title from 1948 to 1972, invented the chess computer programme Kaissa that won the world computer chess championship in 1974.

The July test made global headlines when it emerged last month that the vehicle had flown into space and completed a partial orbit of the Earth.

Harkening back to Sputnik even more recently, Russia registered the world's first coronavirus vaccine, which it named Sputnik V, in August 2020 in the midst of the world's worst pandemic in a century.

Although the move triggered criticism both at home and abroad over the fast-track procedure, a leading medical journal later said it is safe and highly effective.

The vaccine has been registered for use in dozens of countries.
