Commentary:
America as a Space-faring Nation
Charting
the space program’s next great leap forward

When
chunks of the space shuttle Challenger’s left wing washed up on
Cocoa Beach, Fla., as 1996 drew to a close, they triggered haunting
memories for the space program and the nation. But perhaps the corroded
scraps of metal were offered up by the sea as testament to how far the
space program has come, 11 years after its worst disaster.
Seven
astronauts perished on Jan. 29, 1986, in a fireball of debris moments
after launch, an image forever seared into the American consciousness.
Then
in a rash of headlines last year, the space program, as if to dispel
any doubt whether it had fully recovered momentum after its most stagnant
decade, boasted a string of triumphs. Indeed, riding and extending that
momentum, space shuttle Discovery astronauts are presently on a flash
four-spacewalk mission to upgrade the Hubble Space Telescope. If successful,
the 10-day overhaul will dramatically improve the orbital observatory,
which has already yielded an unparalleled glimpses of the universe,
including the first definitive peek at black holes.
It’s
been a long time. But clearly the space program is on a roll. Things
really got going last August when detection of possible microbes on
a Martian meteorite rekindled speculation that life on earth is not
an accident but a statistic. Within months two more probes, the Pathfinder
and Surveyor, were simultaneously making the 310-million-mile trek to
the crimson planet, with President Clinton’s enthusiastic blessing.
Water
on the moon, previously shrugged off as extremely unlikely if not impossible,
suddenly verged on fact with the discovery of what scientists believe
to be lunar ice. That potential oasis immediately stirred new dreams
of a moon colony, from which deeper manned space missions could be launched.
Not only could the water help sustain life, but if it were broken up
into its component elements of oxygen and hydrogen, it could turn the
moon into a lunar gas station to fuel rockets cheaply.
And
not to be outdone by our moon, the presence of ice floes on Europa,
that far-flung Jovian satellite, were corroborated in January.
Then
embodying what portends to be a new era for space exploration, Shannon
Lucid was awarded the Space Congressional Medal of Honor for her 188-day
sojourn, the longest for an American astronaut, orbiting earth in a
joint mission with Russian. She may be just the role model to inspire
the next generation of astronauts and their financial patrons.
After
Clinton slipped the bulky medal around her neck, Lucid hailed our country’s
imminent future as “a space-faring nation.” With 60 shuttle
missions launched successfully since the Challenger tragedy, that may
already be a fair description. In the immediate wake of the explosion,
however, followed by several explosions of unmanned rockets, NASA –
the National Aeronautics and Space Administration – seemed paralyzed.
It
would be three years before a shuttle would again soar through space.
Critics
charged NASA was as unfocused as the Hubble telescope’s mirrors.
And then the Mars Observer probe ended in an abrupt fiasco when it apparently
blew up while trying to establish its reconnaissance orbit. The Galileo
probe to Jupiter suffered from a stuck antenna.
But
NASA was overhauling itself, going over every shuttle flight rule, looking
at every piece of hardware, taking nothing for granted.
Management
was shaken up and slimmed down. One result was a renewed focus on unmanned
missions that may be less ambitious, but can be launched more cheaply
and more often.
Last
year’s impressive feats are just the kind to generate the public
support crucial to the fate of the agency’s next major goals,
particularly its manned missions, which remain decidedly ambitious –
and controversial. One the drawing board are the International Space
Station; the Origins Program, which traces through the birth of the
universe through the first signs of life on earth; a manned landing
on Mars; a lunar base, and replacing the shuttle with the X-33, a single-stage
reusable vehicle.
These
grand schemes depend on shaking loose more money in times of tight budgets.
NASA’s future depends on repackaging its venerable argument that
its endeavors invariably yield technologies benefiting our everyday
lives. For example, a precision, nonsurgical breast biopsy technique
derives from technology developed for the Hubble imaging system. It
is saving women pain, scarring, radiation exposure, time and money.
And
if nuclear fusion should ever become perfected, Helium 3 deposits on
the moon could solve energy shortages.
Commercialization
of space, experts say, looms as a potential gold mine. But the prospects
are not presently tangible enough for the average person to fathom.
NASA still needs to sell the spectacular, the notion that great nations
do great things.
Putting
a man on Mars or building a lunar base would unquestionably be impressive
and qualify as great things to a great many people. The first components
of the $17.4 billion International Space Station, a great example of
cooperation between 15 nations, are slated for launch in November, although
delays in delivery of a Russian service module, a key propulsion and
living space component, may postpone that timetable.
Even
in times of fiscal sobriety, it’s those spectacular feats, the
giant leaps toward understanding of our universe, and perhaps advancement
of the human species, that draw the most support for expanding our horizons
beyond this planet. This year bodes more of the same for our fledgling
space-faring nation.
