Shame we can't educate these conspiracy nuts about electromagnetic radiation: microwave ovens, wifi, mobile phones, cell towers, even the CPU in your PC/laptop emits some measurable GHz 'beamz' !
Therefore, they should do the only sensible thing: limit their communications to good old pen and paper.
You know it makes sense
The YouTube channel PBS Space Time, in The Alchemy of Neutron Star Collisions
( https://youtu.be/MmgMboWunkI?t=624 )
summed up the topic thus:
"Neutron star mergers are likely the dominant source of most elements of atomic masses 44 and up, that includes most of the lead, silver, gold, rare earth elements and the radioactive stuff like uranium and plutonium also a good fraction of the molybdenum and iodine which are essential for your biology.
In fact, including the non-essential heavy elements your body masses something like 2ppm colliding neutron star material.
That's only a 10th of a gram or so, but it's a pretty awesome 10th of a gram.
It was, after all, synthesised on the rim of a black hole before surfing a wave of neutrinos into the nebula that would eventually collapse into our solar system... and those atoms would eventually find themselves part of a lifeform that would figure out the very time and distance of their formation."
My company was caught out years ago by silicone contamination of low voltage low current connectors, grease was used to exclude moisture but in a few months micro fibres of silicon/silicon carbide? grew and insulated the contacts. Cleaning the stuff off and replacing all the connectors was entertaining!
Safe levels of silicone contamination for electrical contact:

In the interests of Science, I looked up: Vibratissimo Panty Buster, available from Amazon.
The one Customer Review:
too good to be true..
Unless you have android 4.4 or higher, you cannot use it. Also, the vibration was weak and the ability to connect via Bluetooth too which made it too irritating as you had to spend ages trying to make it connect. I wouldn't recommend it..
Just imagine the situation... "Connect you **** !!!!!!!!"
Second that as a definite read... these days, even if you aren't anything of a chemist and can't see the horrors of using mercaptans as fuel - you can just look it up.
As for SpaceX's successes, I like to think John Carmack's Armadillo Aerospace really showed the way - this sort of rocket science is actually possible.
I'd expect expensive systems to a) ass cover and b) 'meet regulations'...
For only a few million, I could supply 'em with a system that submits a report every 3 days which lists, in a good old hard-copy sort of way, all the attempted logins. If there's a breach, it should be in there somewhere ; )
Laser pointers and sensors has been a 'hack' for years, notably in coin payout mechanisms where a laser pointer would simply flood the has-a-coin-come-out opto on old feed-hopper mechanisms.
We first saw this very soon after the first cheap laser pointers appeared.
Interesting audio attack tho.
Did find this lecture vid from 2015... https://www.youtube.com/watch?v=k1FcDTeOSVI
After 'going too far' I think the Doctor realised he was the one who had to forget, turned the neural block device around and held the 'business end' leaving Clara to push the button end.
Up to that point he'd been holding it by the button end and was very doubtful about being able to 'reverse its polarity'.
Perchlorate brine sounds like a useful source of both H2O and O2, at a pinch you could make a solid rocket from the stuff if you had some fuel.
Bad news for any ancient life-as-we-know-it, perchlorate would've 'eaten' it long ago. So, apart from any extremophiles living on the stuff, the only hope for other life remnants would be deep in CO2 permafrost - maybe.
I hope we go there and find out.
Given the article states:
... catastrophic structural failure at "just above approximately Mach 1.0".
and
... the system must be unlocked prior to reaching Mach 1.8.
It appears there's little margin for error there - I wonder what the actual safe unlock speed was supposed to be? Mach 1.7 ?
I also wonder if it was known that the actuators would be overridden by aerodynamic forces to cause such a movement at Mach 1.0
Unless there was a very specific procedure: "Thou shalt only unlock between X and Y speed", then it should not be classed as Pilot Error.
Behind all this lies the technical question of whether some AI could read a thread and decide, at least as well as some level-headed human, that a 'terrorist discussion' is taking place.
If that were possible, reliable and well-controlled, I reckon there would be a good argument for snooping on lots of communications.
Practically, that is simply not the case.
I definitely don't trust any organisation like Experian which asks that highly-secure, only-that-individual-could-know question: "Mother's maiden name?"
(I did have a bank once ring me to complain that my answer to security question: "Place of Birth" being "Jupiter" must be a mistake on my part)
The problem seems to be that the non-coders making the decisions want fast'n'fancy results, which will end up with some framework being used so Johnny can just type in "My Website" and choose a colour... Hey look - this 9yo just built a website! Film at 11 !
What is really needed is to get across some of the real basics (no, not BASIC), for example - codepad.org have an interactive C editor/interpreter. At the same time, you do also need to give 'em some flashy stuff to keep them interested and to demonstrate the breadth of 'coding'.
You may or may not have heard of Paul Lutus; he wrote "Apple Writer" way back at the dawn of time.
I happened across his arachnoid.com website, looking for HAM radio stuff as it 'appens, then did the Wiki on him to find he's just been deleted ( http://en.wikipedia.org/wiki/Paul_Lutus ).
WTF ?
For a Mars trip, you're mainly worried about just one source of radiation - you only need to protect against particles from the sun... so just tow a large Halbach cylinder of magnets. Nasty charged things headed for you will veer off as they traverse the field.
Not quite so useful against killer krenon-ray wielding aliens tho'
Paris? attractive and highly charged.
