|Climate Data Gaps?25-06-2019 06:24|
Interesting story... I was looking for the launch time, thinking I might stand out in my front yard and watch, first Falcon Heavy night launch. Anyway, it was the payload I found most interesting, some climate monitoring satellites, needed to fill in some of the huge gaps of existing satellites. Didn't NASA just admit that they don't current have the means to monitor the global climate? This sort of confirms that the data in use, to this point is patchwork, and incomplete. Now, I don't blame NASA, they just provide the numbers, it's the 'others' who make use of those numbers, make outlandish claims. My guess would be that most of the 'monitoring' satellites have multiple functions, that we probably don't hear mentioned, but I don't think it coincidence that they are positioned over the more populated areas, more travel areas of ocean.
It's really amazing how fast those satellites are moving, and seldom collide, or damaged by space garbage. I don't know the official count of active satellites, which probably would never be complete, national secrets. But there a quite a few dead ones. It's really surprising, that other countries aren't hacking into satellites, or deliberately destroying them. Many do have commercial uses, but I tend to believe there are some spy functions on most of them. Even competing communications companies should be doing sneaky things to each other's equipment, to steal customers. They do a lot of that on the ground, why not in space?

No satellite can measure the temperature of the Earth. The emissivity of Earth is unknown. We don't have enough instruments to measure it.
At least one nice thing about satellites is that they are all going in the same general direction, west to east. The Earth spins towards the east, and the extra kick you get off the spinning Earth is very useful during launch.
Polar orbiting satellites are few, because it takes so much more fuel for a rocket to enter a polar orbit. No help from the spinning Earth during launch, you see.
