A type 3 what?!

NASA has a long history of seeing its technology turned around after spaceflight for some more earthbound purposes. (Enjoy that scratch-resistant coating on your glasses? Well, it began life as an ‘80s-era spacecraft water filtration system.) What some people miss is that it’s still happening today.
Every year, NASA puts out what it calls a “spinoff report.” No, this is not a list of ideas for a series of zany, roommate comedies set aboard the ISS. (Although this is an excellent idea. Call me, NASA TV!) The spinoff report is actually a list of all the ways NASA’s tech has been repurposed into new products, ranging from the inevitable to the surprising to the bizarre.
Here are a few of highlights from this year’s version:
Merry Christmas, my friends. wink
A massive asteroid flying by Earth on 2015 Christmas Eve has scientists on edge. While NASA is downplaying the threat to human life and property, conspiracy theorists and several experts say space rock 2003 SD220 is larger than believed and has the potential to cause deadly earthquakes and eruptions from dormant volcanoes.
According to a Sun report, the Christmas Eve asteroid is one of at least 10 rocky bodies in space that are considered “potentially hazardous” to Earth. According to an internal report, NASA officials say it measures about 1.5 miles wide and is moving at 5 miles per second.
“The alien landscapes of Pluto and its moons dazzled scientists and nonscientists alike this year. More than eight decades after its discovery, Pluto became much more than a nondescript point of light. It’s a dynamic, complex world unlike any other orbiting the sun.”

This weekend’s Geminids are going to be the biggest meteor shower of this year, and you absolutely should not miss it. Here’s when, where, and how to watch the Geminid meteor shower—and what you should be looking for when you do.
The Geminids are a mid-December (this year peaking on Sunday, December 13th) meteor shower formed by the debris of comet 3200 Phaeton burning up in our atmosphere. Phaeton is unusual in that it was only recently recognized as a comet at all. For many years, astronomers believed that Phaethon was really a large asteroid, due to its total lack of ice. Eventually, researchers figured out that Phaethon’s lack of ice was simply due to how close its path was to the sun, and they reclassified it as an extinct comet or a “rock comet.” That extinct comet is responsible for the Geminids you’ll see this weekend.
An experiment at Fermilab to determine if everything in the universe is just a hologram reassures us it probably isn’t.

Coal miners mine coal; diamond miners mine diamonds; gold miners mine gold; space miners (will) mine space—and anything in it that has precious metals or compounds that can be whisked into rocket fuel. But, just like the first three kinds of “resource extraction,” the celestial kind will face more than a few philosophical, financial, and regulatory complications.
