Sputnik Mission 1957

Putting Sputnik into orbit was one of the most important moments in the history of space exploration.

This project has four parts:

1.- Sergei Korolev preparing the satellite (27 bricks)

2.- Sputnik 1 satellite (77 bricks)

3.- Modified R-7 rocket “Sputnik” (109 bricks)

4.- Relay antenna of the tracking network (18 bricks)

Total: 231 bricks

1.- Sergei Korolev (1907-1966) was the founder of the Soviet space program. Korolev led the development of the first artificial satellite (Sputnik 1), the first human in space (Yuri Gagarin, Vostok spacecraft), and the most succesful launch system that ever existed (Soyuz, still in use today).

2.- Sputnik 1 was the first artificial satellite. It was a metal sphere with four external antennas, It was launched on 4 october 1957 at the Baikonur Cosmodrome. The satellite travelled at about 29000 km/h (18000 mph), taking 96.2 minutes to complete each orbit. It fell from orbit on 4 january 1958, and reentering Earth´s atmosphere, after travelling 70 million km.

3.- The rocket used to put Sputnik in orbit was a modified R-7 Intercontinental Ballistic Missile (ICBM), named Sputnik, with a mass of 272 tonnes, and a lenght of 29 m.

4.- The mission was monitorized from Earth with a tracking network of relay antennas and observation stations. The radio signals transmitted by the Sputnik were monitored by amateur radio operators throughout the world.

I love the history of the space exploration, if you love it too, please support the Sputnik Mission project. Thank you.
