The US program to develop unmanned surface vehicles, called Ghost Fleet, includes a segment named “Overlord” focused on creating a Large Unmanned Surface Vehicle, or LUSV for short. It would be, as the Navy puts it “a high-endurance, reconfigurable ship able to accommodate various payloads for unmanned missions to augment the Navy’s manned surface force.” The Navy has been given $310 million (instead of the $400 million they’d asked for) to build two LUSVs as part of a research and development program....

Carry backup water Water is obviously a critical element on any multi-day hike. After discovering that my back was soaked and my previously puncture-free water bladder was empty not long after stepping outdoors, I’ve learned that everything with H2O requires redundancy. It’s wise to carry both a bladder—like a Platypus for easy, while-hiking consumption—and a sturdier container, such as a Nalgene, just in case the bladder fails. But in all that failing, I’ve found many important answers to my end-trip question, which usually allows for important corrections on future adventures....

A new mission concept out of NASA’s Jet Propulsion Laboratory could allow scientists to explore Venus like never before, all without ever touching the ground. Instead, it will soar high above the skies by balloon. While the NASA mission is still in its experimental stages, the concept involves pairing a small orbiter with an aerial robotic (or aerobot) balloon, about 40 feet in diameter. Though Venus has often been called Earth’s twin due to their similarities in size and structure, the two couldn’t be more different....

When it comes to enjoying music at full volume, we’re biased by what audiologists call the “annoyance factor.” Your favorite song, cranked up in your earbuds, never really feels overly loud but the pounding jackhammer across the street is unbearably noisy—when often, they’re equally dangerous. People adapt psychologically to loud sounds they like—like music—and assume that if sound doesn’t hurt, it’s not hurting them. But, as anyone who’s woken up after a show with ringing ears knows, nothing could be farther from the truth....

You can narrow the search a bit by first asking yourself a few things: Do you want to give him something useful that sets him up for his next stage, or something purely fun and escapist that can take his mind off his goals for a while?
