Strong Tether Challenge

About the Challenge

This is a challenge in materials engineering in which the tether provided by each team is subjected to a pull test. In order to win the $2 million prize, the tether must exceed the strength of the best available commercial tether by 50 percent with no increase in mass. A tether that can win this challenge would be a major step forward in materials technology. Such improved materials would have a wide range of applications in space and on Earth.
