- Hi,
-
- in a recent discussion on a bulletin board here, someone alleged that NASA
- cannot be trusted, because, as he said, it had deliberately deceived the
- public on a number of occasions. Personally, I am rather skeptical of his
- claims (no sources given), so I'd like more knowledgeable folks out here
- to comment on (and preferably, shoot down) these allegations.
-
- Firstly, it was alleged that NASA increased the size of a mountain on
- Venus (no name given) by a factor of 25, to make it more spectacular,
- and make the evening news.
-
- The Magellan "movie" of the venus radar map was indeed stretched,
- - otherwise it would have looked like a scan across a flat plane,
- 10 km mountains are just not that impressive on a 6000 km sphere.
- This was in fact stated in the releases (that I saw) and is not a
- NASA "deception" it's a standard practise in topography.
-
- Secondly, NASA was alleged to have to have manipulated the results of
- surveys of the hole in the ozone layer, saying it was larger than its
- measurements showed.
-
- ??? don't know this one, maybe they chanced which contours to plot.
-
- Thirdly, the well-known COBE graphic, that appeared in all newspapers,
- showing anisotropies in the cosmic background radiation, is alleged to
- have been only a graphic of test results, not of the actual measurements
- themselves.
-
- Well, there exist COBE "synthetic" plots, but the ugly green ones
- are real data, massaged a little bit. They're somewhat deceptive
- as they're noise dominated, that's why you have to analyse the data,
- the published COBE stuff is at the edge of the detectable signal,
- quite franky I'd say the raw data is meaningless to the public and
- that to say the filtered or synthetic data is "deceptive" is insulting
- to whoever bust their ass to get a nice presentable graphic for
- public release.
