A new DARPA solicition seeks "swarming robot space vampires" (in JWZ's evocative phrasing) to disassemble and harvest valuable components from decommissioned satellites before they're decommissioned, to use as spare parts for the stuff that's still functional:
More than $300 billion worth of satellites are estimated to be in the geosynchronous orbit (GEO—22,000 miles above the earth). Many of these satellites have been retired due to normal end of useful life, obsolescence or failure; yet many still have valuable components, such as antennas, that could last much longer than the life of the satellite. When satellites in GEO “retire,” they are put into a GEO disposal or “graveyard” orbit. That graveyard potentially holds tens to more than a hundred retired satellites that have components that could be repurposed – with the willing knowledge and sanction of the satellite’s owner. Today, DoD deploys new, replacement satellites at high cost—one of the primary drivers of the high cost is the launch costs, which is dependent on the weight and volume of antennas. The repurposing of existing, retired antennas from the graveyard represents a potential for significant cost savings.
I dote on fidget gadgets — soothing gizmos intended to give your hands something to keep busy with, like modern worry-beads — and while you can’t buy Chris Bathgate’s amazing machined sliders, and the Fidget Cube Kickstarter just closed, there’s still Thinkgeek’s new Jumbo Noah Fidget Toy, which looks like a lot of fun and […]
VPhone is a wee “phone”, surely the most wee of them all. It has a 1.54-inch touchscreen display, Bluetooth, FM radio, pedometer, 128MB (megabytes!) of storage, a heart rate monitor, some social network-monitoring apps, and a choice of “simple and stylish” black or silver trim. The radio’s quad-band GSM, so if you can get your […]
Withdrawn by Samsung and recalled from store shelves, the explosion-prone Galaxy Note 7 is now forbidden in the skies. The Federal Aviation Administration has officially banned it, via an emergency prohibition order, making it a federal crime to take one on board an airplane. The order restricts passengers from carrying the phone “on their person, […]

The Atmos R2 may be bigger than the brand’s previously-released vapes, but we argue that in this case it’s definitely a good thing. A bigger heating chamber means more room for packing it full. And the bigger battery means longer, more fulfilling vape sessions. In fact, you can use the Atmos R2 for up to about 25 […]
