SUNDAY NATION, November 12, 1972:
Blast Off! 'Coastline' from Adrian Grimwood
IT ALL happens so quickly.
The last 30 seconds 'countdown', 'contact',
'ignition', a cloud of steam and grey smoke, and then . . . 'lift off'. Just as the pencil-like sliver of
silver rises out of the fumes you hear the roar of “blastoff” (something
similar to a drawn out roll of thunder), see the thin projectile soar up into
the sky at an increasingly acute angle and possibly 70 seconds later observe
the successful first-stage burn-out.
From then onwards its mainly guess-work.

You’re looking up into a blue sky thinking you’re
looking at something . . . but you know it is probably out of sight by now. There’s just silence and the crazy
weaving of smoke trails high up in the blue.
The upper winds blowing strange figures with the white fume fingers.
This then, is the scene 17 miles north of Malindi at Kenya’s Ngwana Bay rocket range, where next Thursday the latest weather observation satellite will be fired off into the heavens hopefully scoring another success for the joint US-Italian-Kenyan “San Marco” Upper Space Research programme.

This then, is the scene 17 miles north of Malindi at Kenya’s Ngwana Bay rocket range, where next Thursday the latest weather observation satellite will be fired off into the heavens hopefully scoring another success for the joint US-Italian-Kenyan “San Marco” Upper Space Research programme.
To date technical difficulties have postponed next
week’s proposed launching by almost a month — the previous tentative launch
date was November 02.
These small hitches included a malfunction in the
four-stage American “Scout” rocket’s gyroscope (it had to be replaced with a
spare at the last moment) and then the satellite’s telemetry encoder developed
operating problems (it had to be airfreighted to the States for repairs). The reason mention is made of these
technical traumas is that occasionally even the San Marco projects do foul up,
but in fact, the five-year programme is now being acknowledged around the
scientific world as an invaluable, if modest, contributor to man’s limited
knowledge of his outer environment.
What is the San Marco
programme?
Basically, it’s American science, Italian know-how
and Kenyan facilities to launch scientific satellites into equatorial orbit
around the Earth. What
visitors see out at Ngwana Bay are two skeletal offshore platforms standing 90
feet out of the sea and situated a little less than three miles from the
Ngomeni headland. The southern platform is a long rectangle sitting on the
seabed with its 20 steel legs embedded in the sand. A 120-foot
shelter covers much of this space and houses the dormant rocket during
pre-launch check-outs.
Inside the air-conditioned shelter is the
satellite itself, joined to the rocket head several days before launch.
Surrounding the space vehicle is a scientific array of instruments and
controls.
A large pit on the launch platform’s western end
is left open to the sea and designed to absorb the rocket exhaust of the
Scout’s first-stage motor. Reaching out from this platform, known as the “San Marco” are
23 cables that link into the main control platform, the “Santa Rita” similarly
standing in the seabed some 620 yards north.
Some ideas of the operation’s complexity can be gained from the fact that there are more than 3,000 connections of various kinds linking the two platforms — there are even independent generators producing different electrical voltages to meet scientific equipment requirements.

It is from the “Santa Rita” that the count-down
procedure is run off and the initial tracking undertaken, but the main
communications, supply, mess, housing facilities and other logistical support
is located at the shore-side Ngomeni Base Camp. That is something of the range’s physical
appearance, but a rather less definable substance is the incredible atmosphere
of tension that develops in this tiny corner of the Republic when a launch is
about to take place.
The 200 scientists, technicians and administrators
at the launch operations are predominantly Italian personnel working with the
Universtty of Rome’s aerospace research centre (Centho Ricerche
Aerospazial Dell' Universita Degli Studi di Roma) or CRA for short.
Observing the rituals
shouted out in Latinised-American are a smaller number of U.S. service
personnel attached to NASA’s Goddard Space Flight Centre (who build and test
the US satellites), and a smaller number of visiting journalists and cameramen.
. . and then Malindi District Officer Evan Kinguru, his retinue of
administration assistants and a handful of Pokomo fishermen from the nearby
village.
Everyone is aware of what is supposed to happen — even the village children know how to count-down from ten in English — but it rarely goes according to schedule. The count-down very often goes something like this:
Everyone is aware of what is supposed to happen — even the village children know how to count-down from ten in English — but it rarely goes according to schedule. The count-down very often goes something like this:
“Nine minutes 43 seconds,
“Nine minutes 42 seconds,
“Nine minutes 41 seconds ...
“We are holding on nine minutes 41 seconds
“Still holding on nine minutes 41 seconds”.
On a particularly unlucky day you can be left “holding on nine minutes 41 seconds” for anything up to two hours.
Eventually the count-down really gets into the nitty-gritty Nineties:
“99 seconds, 98 seconds, 97 seconds, 96 seconds
“holding on 96 seconds ...
“We are still holding on 96 seconds ...”
And so it goes until the launch controller might go right through a further 50 seconds and then:
“23 seconds, 22 seconds ...
“Holding on 22 seconds.”
“Nine minutes 42 seconds,
“Nine minutes 41 seconds ...
“We are holding on nine minutes 41 seconds
“Still holding on nine minutes 41 seconds”.

Another unbelievably long pause (it’s only five
seconds) and the count resumes.
“21 seconds, 20 seconds ...”
Everyone is at their cameras: a last check at the
light meters, a quick wipe across the lens: and ...
Concentration, thunder, silence: followed by
exuberant cheers, shouts, dancing on table-tops, a little hesitation from the
more senior scientists awaiting confirmation that the second, third and
eventually fourth stages of the rocket motor have fired properly, and then
they, too, join in the celebrations.
Thursday’s launch will be for a 410 lb. SAS-B
projectile (Small Astronomy Satellite series B) which will eventually orbit
some 345 miles around the earth’s equatorial belt.
That’s pretty much how it all should go … whether
it does has yet to be seen:
We could all have been “left holding . . ."
