There are critics from many corners who condemn the
amounts of money spent in the pursuit of space. Some say
there is no need to waste money playing around in space
when there are so many people right here on earth who need
help and could better use that money that now goes for space
exploration and experimentation.

Morton says, The huge
increase in government-financed research and development
that came with Apollo did not increase America’s overall
technological lead. It may even reduced it, by drawing
scientific and commercial talent into heroic fields and away
from prosaic onesPeople who would scorn to put extra
dollars into welfare payments are happy to recommend that
scientific explorers be given billions, bewitched by the
frontier dreams of manifest destiny (Morton 18).
What Morton and others who hold with his views fail to
take into account, however, are the vast benefits that we
have already realized from space exploration. If we never
gained any more benefits from our own space program than we
have already seen, attaining them was well worth the cost in
We havent heard much environmental comment in the past
ten years from environmentalist actors on television commercials claiming that the ocean would be dead within
seven years. Trained in acting rather than in oceanography
or marine biology, some of these outspoken, visible souls
were misled by other environmentalists in their claims of
the proximity of catastrophe, and lacked either the ability
or desire to educate themselves on their subjects of
interest before speaking out so publicly.
The earths ozone layer is another dying ocean topic.

Unlike the uneducated actors, however, scientists around
the world are working to determine how much of the ozone
related change in the atmosphere is caused by humans, and
how much is attributed to natural processes (Kenitzer
1996). Of the several NASA space labs scattered across the
country, Goddard Space Flight Center is the one most focused
on environmental matters. As such, Goddard teams are
responsible for measuring and monitoring ozone levels found
Launched in 1978 aboard the Nimbus 7 polar orbiting
satellite, NASAs most visible and best-known ozone
research instrument is the Total Ozone Mapping Spectrometer
(TOMS) (Kenitzer 1996) is managed by Goddard and provides
high-resolution maps of global ozone levels. Ozone
depletion data supplied from TOMS has been instrumental in
global agreements to phase out the use of ozone-depleting
chemicals worldwide. The Antarctic ozone hole is seasonal
and cyclical, being most prominent between August and October
of each year. Though we dont yet know how much of
the witnessed ozone depletion is natural and how much is
man-made, TOMS data shows that the seasonal depletion grew
every year between its discovery in 1979 and 1994, when the
depletion was the most dramatic ever recorded.

Since then,
however, the seasonal depletion has been shown to be much
less severe than in the past (Kenitzer 1996).
Goddard manages other environmental survey systems
using data collected from satellite-mounted mechanisms.
TOMS is simply the most visible because of the popular
interest in the topic of ozone depletion, to the point that
its discussion among the most ill-informed of the staunch
environmentalists has replaced the death of the ocean that
Other benefits of the space program concern diagnostic
and monitoring techniques and devices used in the medical
field. Magnetic Resonance Imaging (MRI) is a direct
outgrowth of the system developed for use on manned space
missions, and today is a standard diagnostic tool in every
major hospital in the country (Cone 18). Since it reveals
the structures of the soft tissues within the body,
radiologists no longer are forced to rely solely on X-rays
in order to make a best guess about what might be
happening within an individuals body. No longer relegated
to dealing with visual shadows on X-rays, radiologists can
attain perfect views of internal systems from any
MRI has also moved exploratory surgery closer and
closer to the realm of obsolescence.

That in itself is a
major benefitthere is growing concern and potential
evidence that cancerous growths only begin their rampant
runs after exposure to the atmosphere. If that theory does
indeed prove to be true, then MRI has already saved lives in
numbers of which no one can measure.
Another medical benefit resulting from the necessary
monitoring of manned space expeditions is that of
telemedicine. Telemedicine is the .
