Spacetether.org, or STO, is a collaborative project that aims to facilitate and increase knowledge exchange about tethered satellite systems, space tethers, space hooks and their respective applications. The project has started in 1997 and continues to date. Access to the resources and simulation is limited to STO project members. The research facilitation and coordination is performed by Colombia collaboration and research consulting company Obando Consulting.

The dedication of the STO group is to provide information, analytical papers and technical in-depth resources that have to lead to 'a broader understanding of tether dynamics.

The collaboration and project work between the STO members is supported by a restricted collaborative projects area; you will need the assigned username and password to be able to logon. Contact us for more information.
