![]() ![]() NASA confirms humanity can deflect killer asteroids with rockets - but only if we have years to prepare The key advance made by Blue Alchemist is that its engineers and scientists have taken the byproducts of this reaction-and these materials alone-to fabricate solar cells as well as the protective glass cover that would allow them to survive a decade or longer on the lunar surface. ![]() ![]() Blue Origin makes a big lunar announcement without any fanfare - The company has made both solar cells and electricity transmission wires from simulated lunar soil-a material that is chemically and mineralogically equivalent to lunar regolith. 'Runaway' black hole the size of 20 million suns found speeding through space with a trail of newborn stars behind it - The team concluded that the explanation that best fits the streak is a supermassive black hole blasting through the gas that surrounds its galaxy while compressing that gas enough to trigger star formation in its wake. So far, it has passed multiple tests: fixing circuits by entering tough-to-reach spots and then transforming itself into solder melting into a screw socket and then solidifying to become a mechanical screw and removing a foreign object from a model stomach. Real-life 'Terminator 2' robot can melt to escape jail, then solidify on command - To make the phase-shifting robot, scientists embedded microscopic chunks of magnetic neodymium, boron and iron into liquid gallium (a metal with a low melting point) and left it to solidify. And those experiments could, in the long term, help with safety. Still, the work raises the prospect that we could potentially do some controlled experimental work with lightning, which seems to go strongly against its chaotic nature. All of these strikes involved thunderstorm activity in the vicinity, and the tower was struck several times by bolts that weren't associated with the laser's path. Lasers used to guide lightning strikes to a safe target - This doesn't mean we can randomly call down lightning at will or suck all the risk out of clouds when necessary. ![]()
