The flight of the tethered satellite system
Eos, Transactions American Geophysical Union, 1992 The first Tethered Satellite System (TSS‐1) Electrodynamics Mission is scheduled for launch aboard the space shuttle ST‐46 on July 31, 1992, as a joint mission between the United States and Italy. A 500‐kg, 1.6‐m‐diameter satellite, attached to the shuttle by a thin (.24 cm), conducting, insulated wire (tether), will be reeled upwards from the orbiter ...

An analytical model for wind-driven Arctic summer sea ice drift [PDF]
The Cryosphere, 2016 The authors present an analytical model for wind-driven free drift of sea ice that allows for an arbitrary mixture of ice and open water. The model includes an ice–ocean boundary layer with an Ekman spiral, forced by transfers of wind-input ...
