Sputnik 1 was launched 50 years ago. Fifty years of satellites watching weather, making photos, spying and allowing global communications.
The idea of geosynchronous communication satellites was published in 1945 by Arthur C. Clarke (original work), a famous science-fiction author.
I want say thanks to Clarke, Wernher von Braun and all the imaginative people who led mankind outside his natural boundaries.
Next time you say “damn crappy thing” to your cellphone not getting signal, think about months of walking to reach another city and give a mail (paper mail still exists) to someone.
