Mariner 2's microwave scan of Venus, 14 December 1962. The three swaths show as three bumps (from left: nightside, terminator and dayside), the rest being space and noise. The limb darkening effect (first and third peaks lower than the second) proved that Venus' atmosphere was hot.

Nice to see the raw data like this. |

QUOTE (rlorenz @ Dec 3 2012, 10:10 AM) What's the source of this plot it was printed in Scientific American and Sky & Telescope at the time. I also have the Science article but I don't remember seeing it there. I must check. you can find the same data, with much more details (including scan geometry) here: http://articles.adsabs.harvard.edu//full/1...000055.000.html |
