As we wind down another year we give thanks, mostly, that we are still here to enjoy a look back at what were the hottest posts in this space for 2012. First let's start with the end of the world. While it wasn't the most read item of the year, the notion that NASA got out in front of the doomsayers who predicted that by now we'd pretty much be gone because the Earth and civilization were going to end was one of the more interesting stories of the year. NASA put out some videos and had a number of its scientists out putting the kibosh and the supposed "end of times." Indeed, as I write this on December 24 - I think they got it right.
NEWS: The weirdest, wackiest and coolest sci/tech stories of 2012
Anyway, here are the most read Layer 8 blogs of the year.
1. US Navy's high-resolution radar can see individual raindrops in a storm: The US Naval Research Laboratory (NRL) researchers said in June that a very high-resolution Doppler radar it was developing can actually spot individual raindrops in a cloudburst, possibly paving the way for new weather monitoring applications that could better track or monitor weather and severe storms. According to an NRL release, the very high-resolution "Mid-Course Radar" was used to retrieve information on the internal cloud flow and precipitation structure. The radar was previously used to track small debris shed from the NASA space shuttle missions during launch. "Similar to the traces left behind on film by sub-atomic particles, researchers observed larger cloud particles leaving well-defined, nearly linear, radar reflectivity "streaks" which could be analyzed to infer their underlying properties," NRL stated.
3. NASA unplugs last mainframe. It's somewhat hard to imagine that NASA doesn't need the computing power of an IBM mainframe any more but NASA CIO posted on her blog this year that by March the Big Iron will be no more at the space agency.
7. Hypersonic test aircraft peeled apart after 3 minutes of sustained Mach 20 speed: The Defense Advanced Research Projects Agency's experimental Hypersonic Technology Vehicle (HTV-2), lost significant portions of its outer skin and became uncontrollable after three minutes of sustained Mach 20 speed last August. That was the conclusion of an independent engineering review board (ERB) investigating the cause of what DARPA calls a "flight anomaly" in the second test flight of the HTV-2.
9. No bomb powerful enough to destroy an on-rushing asteroid, sorry Bruce Willis: Maybe it's the doom predictions some folks are fearing about the end of the Mayan calendar this year or maybe these guys are obsessed with old Bruce Willis movies. Either way a class of physics students from the University of Leicester decided to evaluate whether or not the premise of Willis' 1998 "Armageddon" movie -- where a group of oil drillers is sent by NASA to detonate nuclear devices on an asteroid that threatens to destroy Earth -- could actually happen. In short - the students found that the device would need to be about a billion times stronger than the biggest bomb ever detonated on Earth -- the Soviet Union's 50 megaton hydrogen bomb "Big Ivan" -- in order to save the world the asteroid.
