There's been a lot of talk lately about what's happening underground, from DARPA's Transparent Earth program to subterranean navigation systems (for real). Not to be out-DARPA'd by DARPA, the Defense Threat Reduction Agency is seeking a "one-time use, air-delivered, highly mobile vehicle" that can tunnel into the earth and deliver a munitions payload underground.
The idea is for the Robotic Underground Munition to make a soft landing after being dropped from an aircraft, at which point it would traverse surface terrain to a predetermined point and start tunneling, autonomously navigating underground until it locates its target. The RUM could then deliver a payload, which could range from a strongly worded letter to a warhead.
Science fair projects don't get much cooler than a texting device that broke the record for deepest known underground digital communication in the United States. Such a device may help save people trapped deep underground and even allow scientists to conduct remote cave research, all thanks to a teen inventor from Los Alamos, New Mexico. NPR took a firsthand look at the deep, dark foray.
Scientists at Case Western Reserve University, Brown University, and several other collaborators are building an underground science lab where, in a 300-kilogram tank filled with liquid xenon, they hope to find dark matter -- the material that scientists believe was instrumental in helping to form the universe.
Don’t tell anyone, but Doug Ausenbaugh has built an underground drug farm—in bucolic southern Indiana, no less. It’s cleverly cached in an old limestone mine near the hamlet of Marengo. There, carefully cultivated stalks flourish under the glare of artificial lights and the rainlike spatter of drip irrigation.
