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.
Peter Biddle writes, “I get I myself into trouble. I don’t claim that bad stuff happens to me more often than others – it’s more that I find more ways to happen to bad stuff. I actually found a way to get severe hypothermia in 105°F heat.”
Looking for a tiny PC that still has space for a gaming-quality video card? SFF PC Cases is a remarkably detailed spreadsheet listing dozens of models, complete with cost, dimensions, volume and even important build tips. The very smallest are not practical for powerful builds, but the critical “Maximum GPU length” field is right there […]
Benji Edwards’s guide to preserving vintage electronics is a fascinating look into all the ways that even solid-state gear can go off in long-term storage: a lot of stuff (batteries, capacitors and even rubber) can leak viscous, electronics-destroying liquids; plastics break down in UV light; mold and corrosion eat your gear from within; spiders, crickets […]
Toaster ovens are the perfect appliance for small things like toasted sandwiches and roasted garlic (try it!), but anything more involved usually requires a full-sized conventional oven.However, despite its small size, the Wolfgang Puck Pressure Oven can handle anything from baked pastries to broiled meats. This kitchen appliance has a minimal countertop footprint, and cooks […]
The Pry.Me Bottle Opener holds tens of thousands of times its own weight, and you can pick one up now from the Boing Boing Store.This remarkable keychain is considerably smaller than any of your keys, but don’t let that fool you: it can easily open any bottle, and could even tow a trailer full of […]
