A Perplexing Modern Conundrum Of A Comet Interceptor...
"Randall Munroe's XKCD cartoon on the ICE/ISEE-3 spacecraft inspired me to do a little research on why Nasa can no long communicate with the International Cometary Explorer. Launched in 1978 ISEE-3 was the first spacecraft to be placed in a halo orbit at one of Earth-Sun Lagrangian points (L1). It was later (as ICE) sent to visit Comet Giacobini-Zinner and became the first spacecraft to do so by flying through a comet's tail passing the nucleus at a distance of approximately 7800 km. ICE has been in a heliocentric orbit since then, traveling just slightly faster than Earth and it's finally catching up to us from behind, and will return to Earth in August. According to Emily Lakdawalla, it's still functioning, broadcasting a carrier signal that the Deep Space Network successfully detected in 2008 and twelve of its 13 instruments were working when we last checked on its condition, sometime prior to 1999.
Can we tell the spacecraft to turn back on its thrusters and science instruments after decades of silence and perform the intricate ballet needed to send it back to where it can again monitor the Sun? Unfortunately the answer to that question appears to be no. 'The transmitters of the Deep Space Network, the hardware to send signals out to the fleet of NASA spacecraft in deep space, no longer includes the equipment needed to talk to ISEE-3. These old-fashioned transmitters were removed in 1999.' Could new transmitters be built? Yes, but it would be at a price no one is willing to spend. 'So ISEE-3 will pass by us, ready to talk with us, but in the 30 years since it departed Earth we've lost the ability to speak its language,' concludes Lakdawalla. 'I wonder if ham radio operators will be able to pick up its carrier signal — it's meaningless, I guess, but it feels like an honorable thing to do, a kind of salute to the venerable ship as it passes by.'"
But we can spend on things to better control our Chemtrailing operations.

While I am not doing Facebook I still always wondered why so many people quest to get what
are called "Friends." Now I think I understand. And of course my two readers will also now understand. Who knew?
"In an upcoming issue of the Journal of Computer-Mediated Communication, researchers conducted an experiment on the impact of the number of Facebook friends a person has on impression formation. When viewing modified Facebook profiles (all with the same profile picture and an experimentally controlled number of friends), people rated profiles with lots of Facebook friends as more physically attractive, more socially attractive, more approachable, and more extroverted. Since potential employers look at Facebook profiles these days, perhaps it's time to hire some Facebook friends."

Ahh...Gee I feel so sorry for them...not!
Perhaps if all the carriers were to charge more...hmm...
The Federal government thinks Sprint overcharged them $21 million when billing for wiretaps. From the article: "Sprint, like all the nation's carriers, must comply with the Communications Assistance in Law Enforcement Act of 1994, which requires telcos to be capable of providing government-ordered wiretapping services. The act also allows carriers to recoup 'reasonable expenses' associated with those services. Sprint inflated charges approximately 58 percent between 2007 and 2010, according to a lawsuit the administration brought against the carrier today. ... The suit said that the wireless carrier breached Federal Communications Commission guidelines of 2006 that prohibited carriers from using intercept charges to recover costs of modifying 'equipment, facilities or services' to comply with the Communications Assistance in Law Enforcement Act."

Oh ya...this is gonna work...LOL

High-bypass turbofan engines do not create condensation trails.
The ratio of air-to-exhaust is much too high to facilitate the
formation of condensation because the majority of air expelled from the
back of the engine is not combusted. It is passed through the "fan" and simply blown out the back without mixing with any fuel at all.
Turbine engines are the power plant for high-bypass turbofans. Turbine engines are used in other applications besides powering jets. They are also used to power helicopters, yet we never see trails coming from helicopters, and the reason is simple. Turbine engines almost never produce condensation trails.
