Laser Weapon Being Developed to Deflect Killer Asteroids

An asteroid exploded over the Atlantic Ocean without warning last month, unleashing the force of multiple nuclear weapons into the atmosphere. It could have caused extensive damage had it hit in a populated area. If only there were some way to shove these killer asteroids off of their killer path before they blast us to bits. Researchers in California say their asteroid-deflecting laser weapon has been tested on a small scale and is ready for a full-sized model.
Generally speaking, the technology is available today. The main challenge with building a full DE-STAR is the necessary scale to be effective.
That’s Qicheng Zhang of the University of California, Santa Barbara, from a recent report he co-authored in the Publications of the Astronomical Society of the Pacific, talking about DE-STAR or Directed Energy System for Targeting of Asteroids and exploRation, a project to build a large phased-array laser in Earth orbit to deflect asteroids, comets, and other NEOs (Near-Earth Objects) like the direct hit in February or the monster that exploded over Chelyabinsk, Russia, three years ago.
According to the report, DE-STAR’s laser would heat the surface of an asteroid to the point of vaporization, which would create a gaseous force that moves the object into a new, non-collision path. On a large scale, a DE-STAR with a 330-feet-wide phased laser array could divert an asteroid 330 feet in diameter when it was still two million miles away.

A second, smaller system called DE-STARLITE would position a spacecraft close to the NEO and use low power over a longer time to deflect it. The factors to consider when selecting DE-STAR or DE-STARLITE are size and time, says Zhang.
The bigger the NEO, the longer the time needed. The bigger the laser, the shorter the time needed. With a very small 20 kW DE-STARLITE, a 300-meter-wide (1,000 foot) asteroid can be deflected in 15 years. Smaller asteroids can be deflected in under a year, after the spacecraft’s arrival at the asteroid.

The good news is that the system has already been tested on a small scale at the University of California-Berkeley. A laser was directed at a piece of basalt – a rock similar in composition to most asteroids – under outer space conditions and the rock reached vaporization, emitting a plume of gas with enough force to have pushed it out of its path on this small scale. The researchers also spun the rock and then used the laser to change its rotation and speed.

All we need now is funding. That could come from the potential for asteroid mining that the DE-STAR could aid with its de-spinning capability.
A big killer asteroid might speed things up too.

YOU TELL ME: MORE DEBRIS FROM MH 370 FOUND TWO YEARS AFTER THE EVENT?

I can't help it, but I am just skeptical of the whole Malaysia Air flight 370 disappearance, and have been since the story broke just a little under two years ago. And every now and then, as we've seen since it's disappearance, there's a story about debris being found thousands of miles away from where it was supposed to have crashed, or there's a story of people or debris found in other places, all of which - I can't help it - makes me think that someone might be trying awfully hard both to (1) keep the story alive and (2) keep everyone looking in the wrong direction, or at the wrong thing. I can't help it, but that's my intuition. Nothing less, and nothing more.
So, as we approach the second anniversary of its disappearance, once again there is more debris in the headlines, as this article shared by Mr. C.S. shows:
Washed-up debris from same type of plane as missing MH370, official says
As noted, this most recent find appears to be that of a horizontal stabilizer:
Debris that washed up in Mozambique has been tentatively identified as a part from the same type of aircraft as the missing Malaysia Airlines Flight 370, a U.S. official said Wednesday.
Photos of the debris discovered over the weekend appear to show the fixed leading edge of the right-hand tail section of a Boeing 777, said the official, who spoke on condition of anonymity because he wasn't authorized to speak publicly. MH370, which disappeared two years ago with 239 people aboard, is the only known missing 777.
People who have handled the part, called a horizontal stabilizer, say it appears to be made of fibreglass composite on the outside, with aluminum honeycombing on the inside, the official said.
After the usual pro forma warnings against wild speculations - which we'll get to in a moment - the article then reviews the MH 370 saga:
Flight 370 disappeared on March 8, 2014, while flying from Kuala Lumpur to Beijing with 239 people on board. Radar data show the plane turned sharply around as it approached Vietnamese airspace, and then flew back across the Malay Peninsula until contact was lost off the coast of Thailand.
Authorities determined that the jetliner continued on a straight path across the Indian Ocean, leading them to believe that the plane flew on autopilot for hours before running out of fuel and crashing into the water.
Despite an exhaustive search of the ocean west of Australia, where the plane is believed to have crashed, the only confirmed trace of the aircraft has been a wing part known as flaperon that washed ashore last July on the French island of Reunion off the east coast of Africa — about 2,300 miles from the current search area.
...
Nothing of the passengers, their luggage or even things designed to float, such as life-jackets, has been discovered despite the largest and most expensive search in aviation history.
In other words, we're left with as many questions as we began with, and on the "official narrative's" view, the principal question of why the plane turned, and then flew south until it ran out of fuel and crashed, remains unanswered. Assuming this debris is from Flight 370, why would any pilot, hijacker, or what have you, do this, and then not make a statement about it? Was the plane commandeered remotely, and then flown until it crashed? If so, why?(And yes, I know about all the technicians on board, the Rothschild patent theory, and all of that, so no need to write and comment about it). Or is debris being "conveniently found" on the anniversary date, to deflect attention from the possibility that no one know anything about the the loss of flight 370. Is not the timing of this find in itself a little sispicious?
All of this is not what disturbs me about this article. What disturbs me is this picture:

Now, what I know about airplane parts you can write on the back of a postage stamp, but something about this is unsettling to me, so perhaps all those airplane experts out there can write in and tell me to relax and remain calm. But until they do, we're being told thesse are a pieces of a horizontal stablizer, so I'm noticing what appears to be two relatively nicely symmetrically round holes underneath the word "NO" boldly stenciled on the piece, and between the two holes(one of which seems to be partial due to a broken off piece), is what appears to be a "fastener" of some sort, with what might be a part number stamped on it. This suggests that what created the holes might have been these "fasteners" popping loose or out. Above these holes, there appears to be a fracture of some sort, which looks like a stress fracture. Bottom line here, it appears that this piece has been subjected to some kind of stress; the only question is, of what kind, and when? Stress in the air? Stress due to impact? Now, obviously, I could be completely wrong. I know nothing about airplane parts, materials science, or any of the things that might dispell my unease in looking at this picture.
So why am I raising these questions? Because, firstly, I think that they're legitimate questions in the absence of any explanation of what we're looking at. Thus, my real point it, I want to know what we're looking at, and I want to know the explanation for what we're looking at. Once there's an explanation, then the real questions can begin to be asked, and maybe, just maybe, we can get to the bottom of happened to the unfortunate victims of Flight 370.
