2. His<strong>to</strong>rical Background<br />
In many areas <strong>of</strong> daily life, such as:<br />
- global communications <strong>and</strong> information transfer<br />
- weather, climate <strong>and</strong> environmental observation <strong>and</strong> forecasting<br />
- remote-sensing/observation <strong>of</strong> the Universe <strong>and</strong> the surface <strong>of</strong> the Earth<br />
- navigation <strong>of</strong> air, route <strong>and</strong> ship traffi c<br />
- human spacefl ight,<br />
the utilisation <strong>of</strong> space systems has become routine.<br />
Just half a century ago, humankind began <strong>to</strong> exp<strong>and</strong> its horizons by conducting missions <strong>to</strong> explore the near-<br />
Earth-orbit environment <strong>of</strong> space. This started with sounding rockets <strong>and</strong> small scientifi c satellites designed<br />
<strong>to</strong> investigate in-situ the Earth’s atmosphere <strong>and</strong> ionosphere, which were at that time <strong>to</strong>tally unexplored<br />
regions. In addition, the fi rst observations <strong>of</strong> the Sun <strong>and</strong> stars using instruments carried by sounding rockets<br />
operating at altitudes above the atmosphere were carried out.<br />
<strong>The</strong> launch <strong>of</strong> the fi rst satellite, Sputnik, on 4 Oc<strong>to</strong>ber 1957 by the USSR prompted the start <strong>of</strong> a space race<br />
between the two superpowers, the USA <strong>and</strong> the USSR, which culminated with the US space programme’s<br />
l<strong>and</strong>ing <strong>of</strong> the fi rst human being on the Moon on 21 July 1969.<br />
Today, space research/applications <strong>and</strong> rocket/spacefl ight technology, along with nuclear-energy exploitation<br />
<strong>and</strong> the mastering <strong>of</strong> advanced data processing/h<strong>and</strong>ling, belong <strong>to</strong> those leading-edge areas <strong>of</strong> technology<br />
that have opened up new technical, economic <strong>and</strong> sociological opportunities, <strong>and</strong> without which a modern,<br />
industrialised country can no longer advance. Spacefl ight, rocket/space technology <strong>and</strong> associated research<br />
have now established <strong>and</strong> proved themselves <strong>to</strong> be a valid means <strong>of</strong> improving our quality <strong>of</strong> life; they are<br />
being relied upon <strong>to</strong> contribute <strong>to</strong> the preservation <strong>of</strong> an inhabitable Earth <strong>and</strong> the long-term survival <strong>of</strong> the<br />
human race. This extraordinary accomplishment <strong>of</strong> the human mind over the last 50-60 years has had a more<br />
pr<strong>of</strong>ound infl uence on our way <strong>of</strong> life <strong>and</strong> work patterns than the public at large realises.<br />
<strong>Rockets</strong> remain <strong>to</strong>day a fundamental element <strong>of</strong> every spacefl ight programme, because they make the transportation<br />
<strong>of</strong> instruments <strong>and</strong> human exploration in terrestrial orbit above the atmosphere <strong>and</strong> also further<br />
away from our home planet possible.<br />
<strong>The</strong> use <strong>of</strong> rockets as sounding rockets for the space sciences was at its most intense around 1957/58, with<br />
activity fl ourishing around during the International Geophysical Year <strong>and</strong> extending in<strong>to</strong> the early 1980s,<br />
but still continues <strong>to</strong> this day.<br />
2.1 Rocket his<strong>to</strong>ry <strong>and</strong> pioneers<br />
<strong>The</strong> early his<strong>to</strong>ry <strong>of</strong> rocket development is closely connected with military applications. After the invention<br />
<strong>of</strong> gunpowder (black powder) in the 13th Century by the Chinese, they used gunpowder-driven rockets for<br />
fi reworks during celebrations, but also as military ‘fi re lances’ in their battles with the Mongols. Via India<br />
<strong>and</strong> Arab countries, early military use <strong>of</strong> solid-fuel rockets reached Europe <strong>and</strong> the USA <strong>and</strong> they were used,<br />
for example, in battle by Napoleon (1803-1814) <strong>and</strong> in the British-American War (1812-1814).<br />
<strong>The</strong> idea <strong>of</strong> civil/scientifi c use <strong>of</strong> rockets <strong>to</strong> explore space emerged only <strong>to</strong>wards the end <strong>of</strong> the 19th <strong>and</strong> the<br />
beginning <strong>of</strong> the 20th Centuries, when spacefl ight pioneers like the mathematics <strong>and</strong> physics teachers Konstantin<br />
Tsiolkowski in Russia <strong>and</strong> Hermann Oberth (author <strong>of</strong> <strong>The</strong> Rocket in<strong>to</strong> Planetary Space) in Germany<br />
proved theoretically that it actually was possible <strong>to</strong> escape the Earth <strong>and</strong> its atmosphere. <strong>The</strong>y developed<br />
independently the theoretical fundamentals <strong>of</strong> rocket fl ight in<strong>to</strong> space <strong>and</strong> proposed <strong>to</strong> use liquid propellants<br />
