2013 Strong Tether Challenge
The Strong Tether Challenge will be held at the 2013 Space Elevator Conference.
If you would like to compete in the 2013 challenge, you can review the competition rules, requirements, tether specifications, and other details in this year's Tether Strength Competition Handbook.
The Strong Tether Challenge requires development teams to create tethers with the highest strength-to-weight ratio. Super-strong tethers will enable many great advances in aerospace capability, including reduction in rocket weight, habitable space structures, solar sails, and various tether-based propulsion systems, culminating in the ability to construct a Space Elevator.
In addition to the strength-to-weight metric, space tethers have to satisfy many other requirements, such as space-environment survivability, specific electrical resistance ranges, damping factors, etc. In the initial stage, the competition will concentrate on the strength-to-weight metric, and we intend to add the other factors in the years to come.
The competition is looking to encourage the development of high strength-to-weight ratio tethers. An entry to the competition requires ready-to-test tether samples.
The intent is to encourage the development of break-through materials. Any award of prize money will require significant advances over the state of the art, rather than incremental advances that only represent optimization in the use of current commercial materials.
All teams must register in order to compete (details in the handbook to be published here soon). The prize is being funded by ISEC and is open to teams worldwide.
