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.
Lured by the internet’s pervasive insistence that it represents a superior, more comfortable typing experience, I recently went back to an old-timey mechanical keyboard. This was a mistake. I am now a hamfisted ASCII jazz disaster.
SpareOne Emergency Phone is a basic cellphone powered by AA batteries. This gives it a relatively short time on a charge, but means that it will have a charge after being stuffed in a drawer or glove box for months. I came across this during my search for the perfect basic phone, but be warned: […]
Low-cost carrier Easyjet has prototyped “Sneakairs,” a pair of shoes that have small vibrating motors and Bluetooth links; they work in concert with your mobile phone’s mapping app, buzzing left or right when it’s time to turn, and twice if you’ve gone the wrong way.
Jared Sinclair developed the RSS reader app Unread, which made $10,000 in its first 24 hours on the iOS market. And we’ve all heard the story of Flappy Bird developer Dong Nguyen, whose creation was reportedly earning $50,000 a day at the height of its 2013 explosion. While those are rare examples, they’re also testament to the […]
