Space Shuttle Project

Space Shuttle Atlantis (STS-46) onboard photo of the Tethered Satellite System (TSS-1) in Orbiter's cargo bay. The Tethered Satellite System (TSS) was a cooperative development effort by the Italian Space Agency (ASI) and NASA made capable of deploying and retrieving a satellite which is attached by a wire tether from distances up to 100 km from the Orbiter. These free-flying satellites are used as observation platforms outside of the Orbiter.
