NASA Drone's Sensors Battle California Wildfires 58

An anonymous reader writes "California is burning, but according to this article advanced sensors on NASA's Ikhana unmanned aerial vehicle (UAV) can detect exact temperatures (within half a degree) through the smoke, enabling the drone to spot for the firefighters battling the more than 300 wildfires. NASA's Ikhana is the same aircraft as the Predator, except it's being used here to save lives."

      I thought its primary function was to gather intelligence, which hopefully has the effect of saving American, allied, and non-combatant's lives. But it does that by letting us kill enemy combatants better, which seems different on its face from what this article talks about.

        There's a misconception here. the simple existence of the predator drone has the effect of denying the enemy or potential enemy freedom of movement, irrespective of the ability/willingness to harm.

        In this particular sense, it forces the conflict down to platoon level , because it is nearly impossible for the opfor to concentrate force effectively; I expect that nothing would suit the allied forces in Afghanistan better than a replay of the Tet offensive, [wikipedia.org] with all the problems of supply and concentrat

            actually, no. the point about the predator is that it denies the free use of space and time, and tactical and strategic surprise. in a asymmetrical conflict in which the good guys have the regular army plus political institutions, THOSE are the ONLY weapons that the terrorists have. try imagining the Viet Nam war with predators roaming in the air equipped with that thermal camera.

            Any military has subcomponents which save the lives of the military personnel themselves. Further, while it hasn't happened recently, once in a while there's on occasion for a defensive war, in which case the military is charged with saving the lives of members of the civilian populace it protects (or allies of the same).

            To be sure, these goals (of saving lives... that one cares about) are addressed by destroying other lives... but even so, it most certainly can be fairly stated that military apparatus can

        Purpose is a goal, aim, intention.

        Function is hat something does or is used for.

        So, the purpose is to carry out the function without risking human lives, on the ground or in the air.

        So the original statement is wrong too. It doesn't save lives so much as it allows recon, surveillance and targetting without risking lives.

        Therefore, the Predator is a weapon system which provides, at a relatively low cost, "Armed reconnaissance, airborne surveillance and target acquisition" with great reduction in risk to friendly soldiers and intelligence assets.

        Bottom line, the damn thing saves U.S. soldiers from bleeding. Sheesh.

      That may be the end result in both cases, but the primary function of Predator is intelligence gathering, and it can lob missiles too.

      And let's not kid ourselves. I think it was Norman Shwartzkopf that said the purpose of the military is to break things and kill people. Even if that is breaking things that would be used against others, and killing those that intend to do harm, it is still breaking & killing, and in the process, there is usually some "collateral damage" to those that had nothing to do with the conflict except to be on the receiving end of shrapnel.

      Also IIRC the Predator has been used extensively for direct strikes against human targets in Afhanistan.

    Has anyone considered the possibility that perhaps these NASA drones are the ones starting the fires? Is it a coincidence that once this technology arrived that the number of forest fires skyrocketed? In a couple of weeks NASA will roll out a better technology and the rate of forest fire creation will plummet. NASA will be hailed as a hero and they will get the budget increases they always wanted--to build their doomsday machines!

      the problem is forests are supposed to burn down from time to time.

      50 years of 'only you can prevent forest fires', strict anti-fire laws, and fast acting fire departments have caused forest debris to build up, resulting in these super infernos.

      more frequent fires = less dangerous fires, more nutrients in the soil, young trees releasing more oxygen into the air, etc.

      an automatic system would seem to work for a little while, but it would only delay the problem. eventually an ueber-inferno will come through and the system will be useless.

      • Mod parent up. Putting out forest fires has proven to be yet another form of short term thinking that gets us into a lot more trouble in the long term. Sometimes you really do have to destroy a forest in order to save it.

          That's a bit simplistic, the idea is to burn the undergrowth not destroy the forrest.
