Americans of my age no doubt remember
The Six Million Dollar Man, a TV-show about astronaut/ pilot Steve Austin, who survives a near-fatal lifting-body accident and is subsequently fitted with cybernetic limbs and assigned a position as a secret field-agent for the semi-fictional
Office of Scientific Intelligence (OSI).Aficionados will recall that one of Steve's special appendages was a "
bionic" eye that allowed him to zoom and filter ordinary visible objects and landscapes, and to "see" in the infrared and ultraviolet bands of the electromagnetic spectrum (not ordinarily visible to the human eye).
So as not to be outdone by Hollywood,
NASA intends to launch a New and Improved 4.5-Billion-Dollar space telescope to replace the aging Hubble telescope currently in earth-orbit.
The new telescope is not simply a replacement, but will represent a fundamental leap in space-observation technology. It's not only much bigger than Hubble, but the new telescope [the
JWST] will take advantage of a longer orbital
baseline [about 188 million miles long] and much more stable location for making far more accurate
3-dimensional surveys of the universe (allowing scientists to REALLY get a perspective on the cosmos [especially relatively proximate potentially habitable star systems, like
Wolf 359 and
Tau Ceti]).
Now spending 4 billion dollars on a space telescope may seem like an extravagant waste of money, but at the rate humankind is trashing THIS star-system's ONLY habitable planet, it may not be too early to look around for new real estate in the neighborhood, even though the
stated purpose of the
JWST is to survey much more distant scapes humankind couldn't reach in tens of thousands of years.
Anyway...the point is that our perspective (in 4 dimensions) may be rapidly expanding...soon. Is it worth the price? Is our actuarial skill advanced enough to even answer the question?
Are we getting too big for our britches?
