LOL!
My step-brother was the former Director of NASA’s Earth Science Program, and later, the Director of the Mars Program.
I barely knew him, and have not seen him since the 1980s, so I have no personal feelings at stake here.
He's a former Navy pilot, so I'd be very surprised if he had any anti-military bias. Of course, he also had strong institutional feelings about NASA, and he was definitely a “Company Man.”
Final question - is any of the DMSP weather data publicly available, or is it classified?
That data would be a valuable counter-weight to NASA’s algorithms.
Some of it is unclassified, but I caution that what is publicly available has been controlled by NASA and is possibly not the raw data anymore.
As far as your bro, it isn’t a matter of pro or anti military. It is “my project funding” versus “their project funding”.
