Comparing Clementine and Chandrayaan-1 spectra from the Moon
(Web Page; Sun Sep 22 11:30:00 CDT 2013)
A paper recently published in the Journal of Geophysical Research illustrates how challenging it can be to try to study a world remotely, from an orbiter positioned a hundred kilometers away. In "Newer views of the Moon: Comparing spectr...
Description: In a paper recently published in the Journal of Geophysical Research, Georgiana Kramer and several coauthors performed a careful comparison of two data sets that seem like they're measuring the same things, so you'd think that the measurements they took would match between the two instruments. But they don't quite match.

In the midst of all this hoopla about Deep Impact, I haven't been able to give the proper attention to Cassini, which began its second year of operations at Saturn today. I hope to pay homage to that next week. In celebration of the anni...
