But it is yet another example of something.

If stuff like this is supposedly hard to come by, how come we are always
coming by this stuff? Don't even get me started on extrasolar planets.

Nope. I'm with Dallas Abbot on this one.

I agree that Arecibo should be kept and even upgraded to whatever
extent is affordably doable.

However, of radar like except X-ray images that should outperform
Hubble resolution by a million fold are within the near future,
although perhaps a terrestrial gamma transmitting and gamma receiving
telescope could best replace Arecibo at 10% the annual cost of
sustaining those old but nicely proven methods that have somewhat
limited resolution.

NASA shelves climate satellites
Environmental science may suffer
By Beth Daley, Globe Staff | June 9, 2006

NASA is canceling or delaying a number of satellites designed to give
scientists critical information on the earth's changing climate and
environment.


The space agency has shelved a $200 million satellite mission headed by a
Massachusetts Institute of Technology professor that was designed to measure
soil moisture -- a key factor in helping scientists understand the impact of
global warming and predict droughts and floods. The Deep Space Climate
Observatory, intended to observe climate factors such as solar radiation,
ozone, clouds, and water vapor more comprehensively than existing
satellites, also has been canceled.

And in its 2007 budget, NASA proposes significant delays in a global
precipitation measuring mission to help with weather predictions, as well as
the launch of a satellite designed to increase the timeliness and accuracy
of severe weather forecasts and improve climate models.

The changes come as NASA prioritizes its budget to pay for completion of the
International Space Station and the return of astronauts to the moon by
2020 -- a goal set by President Bush that promises a more distant and
arguably less practical scientific payoff. Ultimately, scientists say, the
delays and cancellations could make hurricane predictions less accurate,
create gaps in long-term monitoring of weather, and result in less clarity
about the earth's hydrological systems, which play an integral part in
climate change.

``Today, when the need for information about the planet is more important
than ever, this process of building understanding through increasingly
powerful observations . . . is at risk of collapse," said Berrien Moore III,
director of the Institute for the Study of Earth, Oceans, and Space at the
University of New Hampshire.

Moore is cochairman of a National Research Council committee that will
recommend NASA's future earth science agenda later this year. It is unclear,
however, whether NASA will follow those recommendations.

``NASA has canceled, scaled back, or delayed all of the planned earth
observing missions," he said.

Despite NASA's best-known role as a space agency, one of its key missions is
to study the earth. Scientists collect data through ground- and space-based
observatories using instruments that can sense heat and through which they
can see with exquisite detail from many miles up. In recent years, these
missions have increased in importance and visibility as global temperatures
rise and scientists rush to better understand the phenomenon and the role of
humans in it.

While NASA is proposing similarly deep cuts to other important science
programs such as astrobiology -- the search for life in space -- the earth
science mission cancellations and delays take on greater significance, some
scientists say, given recent allegations by a top NASA researcher and other
government scientists that the Bush administration tried to silence their
warnings about global warming

Of what you report is 100% true, and most likely the best available
truth about our resident LLPOF warlord(GW Bush) doing nasty sorts of
things in order to moderate over the scientific truths about global
warming, because his fossil oil, coal and natural gas friends are not
cutting emissions, and energy cost is soaring to boot.

However, since when hasn't our cold-war perpetrating government lied
to us? (we're also talking of trillions spent per decade)

What do you think our NASA/Apollo rusemasters with "the right stuff"
really accomplished to start with?

AmeriKKKa is already a penal colony - with over 3 million AmeriKKKans

There's at least another million inmates we're not even talking about,
plus DoD, MI5/CIA inmates that never get counted. Go figure.

Definitely agree, although it looks like we're in for a devestating
comet shower rather than a single large comet. Commets seem to
periodically hit earth, and we're FAR overdue. See:

Uh... dude, you're a liar. Open the site in another browser if you
believe this guy. If this really happened it had nothing to do with
the site.
