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 have a 64GB iPhone, but I don’t like using iTunes to transfer videos to it because it is a hassle. I have this little $30 USB/Lighting flash drive that holds 32GB of files, including videos, photos, and songs. I plug it into my computer, copy over a bunch of card magic instruction videos, and […]
Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
