Globally, there are 1.5 billion adults who are either overweight or obese, a number expected to increase to 3 billion by 2030. The epidemic is reaching catastrophic proportions, and one of the key-if small- steps to bringing it under control is to have a common language to describe the problem.
The first artificial satellite was Sputnik 1. It was the size of a basketball and was made by the USSR (Union of Soviet Socialist Republics) or Russia. It was launched on October 4, 1957.
The first satellite in space was Russia's Sputnik satellite, carried by an R-7 rocket. The R-7 rocket was built by a team of German and Russian scientists led by Sergei Korolev. Sputnik was placed into orbit on October 4, 1957, months before the first U.S. satellite, Explorer 1. Korolev's team managed to create a rocket big enough to take Yuri Gagarin into space. Gagarin became the first man in space, but the U.S. astronaut, Neil Armstrong, became the first man on the moon. Learn more about Space Travel
