The
Shuttle is the height equivalent of a 15 story building - it weighs 4.5 million
pounds - and NASA is endeavoring to lift it 200 miles off the ground. On TV the
accomplishments looks so much smaller - so much easier. Throngs
of people are standing around with you to watch the Shuttle go. You can feel the
anticipation tingling in your hands. Then the countdown begins through the small
speakers of hundreds of portable radios all tuned to the NASA station. It's enough
to get your heart beating out of your chest. The
tremendous feat starts with one very small human step. During pre-launch activities,
a person pulls a manual lock pin from each of the shuttle's two side booster rockets
- so that at T-minus five minutes, the shuttle's 'Safe and Arm Device' can be
rotated to the 'Arm' position. From
this point on, the primary action is shared by two side booster rockets, three
main engines, on board and command central computers, and eight bolts. The Shuttle
is supported on the mobile launch pad with eight28 inch bolts that detonate on
ignition. T-minus 10 seconds T-minus
9 seconds T-minus 8 seconds T-minus
7 seconds At T-minus 6.6 seconds the
main engine start commands are issued by the on board computers and the three
engines stagger start - all approximately within a quarter of a second of one
another. T-minus 5 seconds. T-minus
4 seconds. The main engines have achieved 90-percent thrust within three seconds.
They are ready to deliver 1.1 million pounds of thrust. T-minus
3 seconds. Computers are initiating all the commands now and they must receive
three simultaneous commands - Arm, Fire 2 and Fire 1 - in order for the pyrotechnics
to begin. The Arm commands signals
a capacitator to 40 volts. The Fire 2 command signals flames from the three main
engines to fire through a thin barrier and down a flame tunnel that is 490 feet
long and 40 feet high. The Fire 1 command is issued to arm the side boosters to
deliver 6.2 million pounds of thrust. T-minus
2 seconds. T-minus 1 second. T-minus
Zero: The side booster rockets are ignited and the eight explosive bolts blow.
When the bolts detonate the shuttle is free to move. And the bolts fall into a
tray of sand.
The first thing you
see are large billowing white steam clouds blasting away from the rocket because
300,000 gallons of water is being flooded in to deaden a reverberating sound wave
that would shake the shuttle into fragments. Through
the steam, at the base of the skyscraper-like- rocket, you see the fire power
- and it's brilliant red, white-hot-orange, and blinding yellow. Then the Space
Shuttle begins to inch off the pad. Your
chest is thumped with an inaudible shock wave an instant before your ears are
filled with a roaring thunderous sound. And
the shuttle inches, and inches, and claws its way upward - so slowly at first
that you swear a full ascent would never be possible. Barely moving. Burning up
massive amounts of fuel. Thousands upon millions of pounds of thrust lifting the
shuttle hardly at all. .... But with ever increasing ease, the shuttle picks up
and roars into the sky, headed into space attaining a speed of over 17,000 mph. It
is within the first two minutes off the Space Shuttle launch where the great success
lesson is present. Fact: 85% of the shuttle's fuel is expended within the first
2 minutes just to get the 15 story super structure 1/12 or less than the 10 %
of the way or journey to it's orbital altitude that is its goal. And
that's exactly how success takes off: The first steps you take towards launching
a successful career, project, or product are the hardest and will require an enormous
expenditure of energy - a great big push. However,
if you persist through the launch phase, which can seem almost futile for quite
some time, guaranteed - everything get's easier and easier and your results get
bigger and bigger. Do the work and
effort it requires to get off the launch pad towards your goal. Astronauts
