The
system of measure has demolished Mars Climate
Orbiter
|
Metric
decimal system and system of Anglo-Saxon measure
are been met doing an illustrious victim: the probe
Mars Climate Orbiter, that has broken on the surface
of the Red Planet. Seem unbelievable, I have gone
quite as, like recite a statement official of the
Jet Propulsion laboratory from the NASA that pursued
the probe. And for an error of conversion from the
tables of the Lockheed Martin builder of the vehicle,
in "feet", to those of the NASA, in meters,
the vehicle has stayed made approach to the planet
to a quota too low (57 kilometers) instead of the
186 km scheduled. Three different investigations
have stayed open for understand above all like never
in the chain of the controls and of the verifications
the error is survivor without nobody if notices
some. has resulted in fact what an analogous error
of conversion had also taken place during the trip
in the evaluations of the trajectory, above all
in the phases in which one they effected the scheduled
corrections lighting the propellers. But in the
I space the error didn't cause consequences and
didn't emerge his in the problematic. In fact, nobody
if had realized some. But when the probe is been
found before the Red Planet and the last correction
has stayed finished mistake again, from the long
verification sprang finally the trouble. But it
was too much delay and there was not more the time
of correct it. Who knows that the serious material
damage and to the image of the spatial corporate
body don't force finally to abandon the system of
measure Anglo-Saxon that stays in life still in
the United States while in best part of the world
is used the metric decimal system. It would be time
that also the American giant conforms.
