Founded in 1994 by Robert P. Hoyt and Robert L. Forward, Tethers Unlimited began developing products based on space tether technologies, including concepts for removal of space debris[4] and momentum exchange tethers for launching payloads into higher orbits.
In 2007, in collaboration with Stanford University, the company launched the Multi-Application Survivable Tether (MAST) experiment to test the survivability of tethers in space.[5][6][7] In 2016 it was reported by SpaceNews and Yahoo that the company's subdivision Firmamentum signed a deal with SSL to fly its in-space manufacturing technologies on SSL's Dragonfly program which is funded by NASA's Tipping point initiative.[8][9]
In December 2018 it was reported that Tethers Unlimited delivered a Refabricator to the ISS that accepts plastic material and converts it into high-quality 3D printer filament,[10] for the mission duration of October 2018 to April 2019.[11]
On May 6, 2020 it was announced that Amergint Technologies acquired Tethers Unlimited,[12] and Amergint and Tethers Unlimited are now subsidiaries of Arka (also based in Colorado).[13]
