Amelia loses consciousness and topples over the side but is saved by her rope tether. "Just Cause 2" includes a grappling hook enabling players to tether objects together. A tether satellite is a satellite connected to another by a space tether. This reduces the required strength of the tether, and makes coupling easier. This is the use of a (typically) non-conductive tether to connect multiple spacecraft. Focal adhesions frequently tether the greater omentum to the cephalad aspect of the transverse mesocolon. This is an instance of the Spring-like Tether gating mechanism. Louis threads it through the ship to tether it to the police station. The open system electrodynamic tether, which uses the ionosphere, is being researched. Max rips off the tether and hurls Kruger over a ledge to his death. She charged him to "Tether this cow safely to an olive-tree at Nemea". A Martian tether could be much shorter than one on Earth. An early experiment used a 500-meter conducting tether. Other possibilities include a momentum exchange tether system. In 1996, NASA conducted an experiment with a 20,000-meter conducting tether.
