Jess (falconry) the bird, but the width is proportional to leg-length. Traditional jesses are made from a single length of leather, and slits are placed strategically along the jess to allow it to be looped through itself and around the ankle of the bird so that it fits comfortably but securely about and just above what would be the bird's ankle. With Aylmeri jesses, as created by Major Guy Aylmeri, the end of the jess is instead looped through itself repeatedly to form a "button", or knob at one end. The thin, pliable end of the jess is then threaded through an
Space tether missions launch lock trouble of the tether reel mechanism." A follow-on Space Tethered Autonomous Robotic Satellite, STARS-II, Iaunched on 27 February 2014 as a secondary payload aboard an H-2A rocket. The 9-kg student satellite flew a 300-metre (980 ft) electrodynamic tether made from ultra-thin wires of stainless steel and aluminium. The mission completed after two months and deorbited on 26 April 2014. One objective of this program was to demonstrate possible technology for de-orbiting space debris. The experiment was only partially successful, and tether deployment could not be confirmed. The orbit decayed from 350 km to 280 km in 50 days,
