The Peace of God to all that belong to the Light,
Dear Readers,

This January 4th of 2018 was the sixty anniversary of the end of the active life of the Sputnik I, the first artificial satellite ever orbiting the earth, also the first artifact sending signals from the earth's orbit ever.

Please check:
sixty years since Sputnik, the satellite that changed the world

When Sputnik was launched in orbit in October 4th 1957 few could know exactly how this so important event was going to change humanity but everybody was sure that it was opening an entire new era in science and technology and it was going to make relatively smaller the world for the generations to come.

Koroliev and the Sputnik I

It was no doubt a shock in America since people in 1957 was unable to understand how it was possible that this satellite was successfully launched in space by the USSR when the United states by that time was already counting about 16 failed attempts to do something similar.

It was the relative more advanced technology in control as well as the more powerful soviet rockets the ones that made possible this huge leap for humanity. Soviet Engineers were already aware of the best techniques of Robust Control that were decisive to explain the overwhelming first achievements of their space program thanks to the so important contribution of Liapunov Stability Analysis that were already found by the so famous Russian Mathematician since the XIX century, something not yet known or fully understood in the west by 1950s.

Sputnik, the start of the space race

Lyapunov stability is named after Aleksandr Mikhailovich Lyapunov, a Russian mathematician who defended the thesis The General Problem of Stability of Motion at Moscow University in 1892.

A. M. Lyapunov was a pioneer in successful endeavoring to develop the global approach to the analysis of the stability of nonlinear dynamical systems by comparison with the widely spread local method of linearizing them about points of equilibrium. His work, initially published in Russian and then translated to French, received little attention for many years

The interest in it suddenly skyrocketed during the Cold War period when the so-called "Second Method of Lyapunov" was found to be applicable to the stability of aerospace guidance systems which typically contain strong nonlinearities not treatable by other methods.

The thread is opened to meditate in the great changes that the telecommunications via satellite have performed in our civilization, something that by the way was predicted to occur more than a decade before the Sputnik flight by the Science fiction author Arthur C Clark.
