NASA solar sail tech passes crucial deployment test
NASA cleared a key technology milestone in January 2024 with the successful test deployment of one of four identical solar sail quadrants aimed for deep space transportation. The deployment mechanisms for the nearly 100-ft-long composite booms that stretch the giant sail membrane use tape-measure tech developed by the U.S. Air Force.

How slip clutches can help maximize your designs
The way they see it over at Polyclutch, there aren't a whole lot of problems you can't solve with a slip clutch. Way beyond using them for overload protection, there are a surprising number of other applications for these versatile and valuable components. From increasing machine speeds and applying constant tension on wire to indexing a conveyor and automatic screw assembly, slip clutches just may provide the design leverage you've been seeking.
