Strong Tether Challenge Announced for August 12
NASA has announced a “strong tether challenge” to be held on August 12, 2011 in Redmond, Washington, as part of its Centennial Challenges competition.
According to the Federal Register notice, the challenge has a $2 million purse and incremental prizes will be offered for entries that meet requirements for strength and mass based on the length of the sample. It will be held as part of the Space Elevator Conference.
Details of the competition are avialable on the Spaceward Foundation’s website, which states that the challenge was first offered in 2005 and asks “will this be the year of the CNT tether?,” a reference to the carbon nanotube (CNT) material from which they hope someday to build a 60,000 mile long tether to function as a space elevator.
