In 1942 the German V2 was the first rocket to reach 100km from the Earth’s surface (the boundary of space).
The rocket was designed by Wernher Von Braun, who later worked with NASA as the creator of the rockets that went to the moon
In 1947, the first animals were launched into space. Fruit flies were used to study the effects of space travel on animals, and were chosen because they are more similar to humans than you might imagine!
The flies travelled with a supply of corn to eat on the flight.
Albert II, was the first monkey in space. He was a Rhesus monkey, a type of monkey that originally comes from Asia.
Albert went into space on 14th June, 1949 in a specially adapted American V2 rocket, that flew to a height of 83 miles from earth.
On 4th October 1957, Russia launched the first satellite into space; Sputnik 1, and the space age had properly begun!
Sputnik was the first satellite in orbit around the earth. Today there are over 500 working satellites in space. Sputnik means "Satellite" in Russian.
In November 1957, the Russian space dog Laika became the first animal to orbit the earth.
Laika travelled in a spacecraft known as Sputnik 2. Laika means "Barker" in Russian, and her mission helped scientists understand whether people could survive in space.
On 12th April 1961, Russian Cosmonaut Yuri Gagarin became the first man in space. Gagarin's spacecraft, Vostok 1, completed one orbit of the earth, and landed about two hours after launch.
Gagarin had to bail out and land using his parachute, because the Vostok 1 was designed to crash land!
By 1959 Both American and Russian scientists were in a race to get a spacecraft to the Moon; the Russians made it first.
Space-probe Luna 2 crash-landed into the moon at a speed that would kill an astronaut if one had been travelling in it! It was ten more years until a human visited the moon's surface.
In 1963 US President John F. Kennedy promised the world that the US would land men on the moon before 1970. Before risking people's lives, NASA sent a robot spaceship, to make sure they could land safely.
It was called Surveyor 1, and it made the second soft landing on the Moon on 30th May 1966, a few months after Russian probe Luna 9 landed successfully.
On 20th July 1969, Neil Armstrong, and then Buzz Aldrin took "one small step" and became the first men on the moon. The first words said on the moon were "the Eagle has landed". Their spaceship, Apollo 11 worked perfectly, flying them 250,000 miles to the moon, and bringing them all the way back safely to earth. Buzz was a childhood nickname - his real name was Edwin!
From 1971 American astronauts on the fourth, fifth and sixth Apollo missions enjoyed use of a moon car to explore the moon. Known as the Lunar Rover, it was electric powered, and had a top speed of 8mph.
It was designed and developed in only 17 months, by Boeing, the aeroplane company famous for making the Jumbo Jet. Find out more here.
Two days into its journey to the moon, on 13th April 1970, Apollo 13 suffered an explosion caused by a wiring fault. Using only whatever was on board, NASA scientists and the astronauts on board improvised repairs to bring the crippled spaceship home.
The mission was a successful failure: although the crew never walked on the moon at least they made it home alive!
Nasa are enthusiastic about getting a man on Mars.
Nasa wants to see if there is life on jupiters moon Europa.
