This is an interesting study of the intersection of politics and science at NASA:
The new dramatic invention of the inventor of the Internet was to place
a satellite so far that the whole Earth can be observed 24 hours a day.
Isn't it fascinating? Why didn't you think about that? Some
scientists refined the details for him - for example that the satellite
should be located in the L1 Lagrange point. The price? Well, the first
modest estimate was USD 135 million.
If you think about it for a
while, the scientific content of this project is next to nil. It is a
typical idea of a crackpot who has no tools to determine whether a
project is scientifically interesting or not. Already in 1999, during the Clinton-Gore administration, the project - nicknamed GoreSat or Gore's Screensaver - was more or less doomed. NASA Inspector General has also determined that the project is driven by politics, not science. It was found that the budget estimate was underestimated, too.
did they ever justify to study that project at all? Did they just tell
NASA that it has appeared in a dream of a prophet? Well, Al Gore wanted
the fresh picture of the whole Earth (well, just one-half, but it's OK)
to be constantly available as a source of inspiration: people could
finally see through the Internet, his other invention, that the Earth
is a little vulnerable child who has a fever. NASA added some
survey tasks, including measurements of the albedo every fifteen
minutes, that were not really needed and that are effectively performed
by existing devices, for example by CERES.
