First Telescope
The first telescope was invented by Hans Lipperhey, with contributions from Galileo Galilei. This happened when Lipperhey combined two lenses. Now scientists could see farther into space. -
First Moon Spotting
Galileo got the first glimpse of the moon using a telescope. This allowed people to see what the moon looked like closer up. -
Multistage Rocket Patented
Andre Bing from Belgium patented the multistage rocket created by Robert Goddard. These multistages allowed to reduce the weight of the rocket. There is no use of the fuel tank once it is already in space. -
First Liquid Fueled Rocket
The first liquid fueled rocket was launched by Robert H. Goddard. This increases the efficiency of the rocket. The speed was 60mph, altitude was 41ft. Was fueled by liquid oxygen and gasoline -
Sputnik was Launched
The Soviet Union launched Sputnik, an artificial earth satellite. It was successfully put into the Earth's orbit in 1957. -
Explorer 1 was Launched
The first satellite was launched by the USA called "Explorer 1". It was built by Jet Propulsion Laboratory (JPL). The satellite was put into orbit on January 31, 1958. -
First Human in Space
The first human in space was Yuri Gagarin from Russia. Then we could know that humans could survive in space atmosphere using the right equipment. -
First man to walk in space
The first man to walk in space was Alexi Leonov. Humans could survive in a space environment with the right equipment -
First Men on the Moon
Neil Armstrong and Buzz Aldrin were the first men to set foot on the moon. They landed on July 20, 1969 and gathered moon rocks, observations, and other tests for the scientists back on Earth. -
Skylab was Launched
The USA launched "Skylab", the first space station successfully into space. Now scientists could study in space. -
First Space Shuttle
On April 12, the first space shuttle "Columbia" was launched successfully into space by the USA. A space shuttle was reusable and way more efficient. -
Challenger Explodes
The space shuttle "Challenger" exploded seconds after liftoff killing all seven passengers. The O-rings were not tested in extreme cold, and during the launch in the morning the cold rubber became stiff and failed to seal the joint. -
Hubble was Deployed
Space Shuttle "Discovery" deployed Hubble Space Telescope successfully into orbit. Now scientists could explore Earth and the solar system easier. The atmosphere was not in the way of the telescope so images were much clearer. -
International Space Station Launched
The ISS was launched to further scientific research in space. The contributors were USA, Japan, Canada, Europe, and Russia. Now scientists could study in space. The ISS costed 150 billion dollars. -
Columbia Broke Apart
A small piece of insulating foam broke off the fuel tank, and smashed into the wing of the shuttle. It damaged a tile that protects the shuttle from high temperatures. Columbia couldn't stand the temperature and broke apart when coming back into the Earths atmosphere.
