The mission -- called MAST (for Multi-Application Survivable Tether) -- is scheduled to begin April 17th with a payload launch on a Dnepr rocket from the Baikonur Cosmodrome in Kazakhstan, after which the Washington state-based Tethers Unlimited's two anchor sats (less-cleverly dubbed Ted and Ralph -- um, hello, Penny and Brain...) will gradually separate until they've pulled the kilometer-long line taut.
