Leaving Home. Into the Unknown.
The Universe is
incomprehensibly vast and about 13.8 Billion years old. There are at
least 100 Billion Stars in our Milky Way Galaxy alone and according
to current estimates, there are at least 200 Billion Galaxies in the
observable Universe. Some estimates reach around 2,000 Billion
Galaxies, not to mention the Trillions of Planets, Suns, etc.. They
say that there are more Stars in the Universe than grains of sand on
Planet Earth. The circumference of the Earth is about 40,000 klms.
High frequency radio waves, being electromagnetic radiations travel
at the speed of light, about 186,000 miles per second, basically
being received instantaneously around the World. Depending on the
relative position of Mars from Earth, radio waves can take up to
about 20 minutes to reach the Red Planet. The Space Craft Voyager 1
has been traveling away from Earth for over 40 years, having been
launched in 1977. It's currently in interstellar space and over 13
Billion miles away. It's radio signals take something like 19 hours
to reach home. Due to the time delay in Radio Communications, as we
strengthen our influence in Space, a new form of Communication will
need to be invented. If interested in a new Communication System,

If we can befriend ourselves and then each other here on Planet
Earth, then our destiny lies out there in Space. Exploring and
Imagine for a moment, what this World of ours would be like without
Radio Communications. They're vital to our way of life and without
our current understanding of our place in the Universe which is
largely due to Radio Communications, we would still be living in the
How dependent are our Defense Forces on Radio Comms.
Italian inventor and electrical engineer, Guglielmo Marconi is
credited with the first transatlantic telegraphic radio
communications in 1901 and now the hobby of Amateur Radio has been
around for well over 100 years. We stand on the shoulders of those
who have gone before us and their hard work and contributions.
Amateur Radio can be a gateway to the advancement of our
civilization. It's in our nature to go beyond. Looking towards the
future, we need to see over the horizon to the possibilities and the
hope which is there. Remote control of Amateur Radio Stations is now
a reality and remote control of advanced technologies in Space also
require Radio Communications. As we slowly further Our Reach into
Space, Radio Communications will help us to broaden our horizons and
we will realize, if we survive long enough, how insignificant we are
in the grand scheme of things and also how futile it is not to work
together. Perhaps one day with this expansive view of our place in
the Universe, we may then gradually be able to leave conflict
The International Space
Station has a dedicated Amateur Radio Station on board with which
Astronauts talk to classes of School Children in many Countries on
