This day 50 years ago a human being made the first flight into the outer space. It was a Soviet cosmonaut – Yuri Gagarin.
Nowadays we can often hear that Russia lost its leadership in space activities.

We got down to facts and learned what country has now the most satellites and is a heavy space litterer.

We invite you to predict when China will overtake America

CHINA jumped ahead of Japan in 2010 to become the world’s second-biggest economy, but when will it grab the number-one slot? The Economist’s interactive chart allows you to make your own predictions. The relative paths of GDP in dollar terms in China and America depend not only on real growth rates but also on inflation and the yuan’s exchange rate against the dollar. Over the past decade real GDP growth averaged 10.5% a year in China and 1.7% in America; inflation averaged 3.8% and 2.2% respectively. Since Beijing scrapped its dollar peg in 2005, the yuan has risen by an annual average of 4.2%. Our best guess for the next decade is that annual real GDP growth averages 7.75% in China and 2.5% in America, inflation rates average 4% and 1.5%, and the yuan appreciates by 3% a year. Plug in these numbers and China will overtake America in 2019. But if China’s real growth rate slows to an annual average of only 5%, then (leaving the other assumptions unchanged) China would become number one in 2022. Please place your own bets.
