US Air Force Wants To Plasma Bomb The Sky To Improve Radio Communication (newscientist.com)
An anonymous reader quotes a report from New Scientist: [The U.S. Air Force has plans to improve radio communication over long distances by detonating plasma bombs in the upper atmosphere using a fleet of micro satellites. It's not the first time we've tried to improve radio communication by tinkering with the ionosphere. HAARP, the High Frequency Active Auroral Research Program in Alaska, stimulates the ionosphere with radiation from ground-based antennas to produce radio-reflecting plasma.] Now the USAF wants to do this more efficiently, with tiny satellites -- such as CubeSats -- carrying large volumes of ionized gas directly into the ionosphere. As well as increasing the range of radio signals, the USAF says it wants to smooth out the effects of solar winds, which can knock out GPS, and also investigate the possibility of blocking communication from enemy satellites. [There are at least two major challenges. One is building a plasma generator small enough to fit on a CubeSat -- roughly 10 centimeters cubed. Then there's the problem of controlling exactly how the plasma will disperse once it is released. The USAF has awarded three contracts to teams who are sketching out ways to tackle the approach. The best proposal will be selected for a second phase in which plasma generators will be tested in vacuum chambers and exploratory space flights.]
please use your missile satellites to knock off those flying US turds. Enough of the world has been bombed by USA as it is.
Bearing in mind that public funds are involved here, I'm struggling to understand why improving radio communications using "plasma bomb" satellites is such a great idea when satellites already do such a great job improving radio communications. In other words, we have vast numbers of artificial ionosphere "bouncers" already orbiting our planet, and we can also have high altitude tethered balloons and long duration airborne aircraft (perhaps solar electric) that the likes of Google and Facebook are working on -- and with much less investment than even one copy of the some of the aircraft the U.S. Air Force flies. We already know how to bounce radio signals all around the globe, and it's already cheap, reliable, and secure. So what's the "value add" here that merits substantial public investment? Anybody have any ideas?
That assumes operation in industrial nations, which is not where any military deploys on a regular basis. For the same reasons significant research has been done in remote power generation including using radioactive decay for nuclear power without building a reactor. Environments differ, and your knowledge of your mother's basement has little application to a battlefield in Afghanistan or anywhere else with rugged and inhospitable terrain.
Given the size of ionosphere, the ionisation density and recombination rate, and the size of a micro satellite this project looks like trying to deplete Lake Tahoe with a teaspoon...
Although the sun naturally "pollutes" the ionosphere every 11 years in the sunspot cycle and spread spectrum short wave communications is still a major military technology?
Facts are history now plebs have politics for religion on social media.
Just put order of magnitude in this plan, and you see this is pure bullshit.
where ionosphere bounce is rapidly becoming an outdated method.
Hate to break it to you, buddy, but it's still the only infrastructure-free method of global communication, which means it's just as effective as when it was first discovered. Your massive satellite/cable network is great for when everyone's playing nice and is OK with a small group of people having control of almost all the information flow, and your ionospheric propagation remains good otherwise.
tl;dr Progress is good, but should not be misidentified nor misinterpreted. 2.
This said, changing propagation characteristics of the ionosphere seems to be a crap idea. Or, rather, it's an obvious idea with consequences that haven't really been thought through.
"Sorry Mr. President, we can't move in to take that territory until we run some more fiber, should take a few months at best. I'm sure the enemy will wait around for us, no problem."
Oh wait, I forgot enemies are illusions and humans are all really one big happy family who would never want to kill each other for any reason other than nation states and religion. My bad.
So let me get this straight: We all have to worry about Hairspray, Cow Farts, and every other perceived man-made cause of "Climate Change" (f/k/a "Global Warming"); but now we want to intentionally "pollute" the ionosphere?
What could possibly go wrong?
