The Optel-μ Implementation Study on ISS has been set up to assess the feasibility of an IOD (In Orbit Demonstration) of the Optel-μ Space Terminal on the ISS (International Space Station).
The Optel-μ system provides an optical data downlink from a LEO (Low Earth Orbit) S/C to an Optical Ground Station with a data rate up to 2Gbit/s. It is being developed by RUAG Space in the frame of the ARTES program

The BOUNCED project has assessed the behaviour of elastic tethers within flexible link Active Debris Removal (ADR) systems. This has been achieved by solving a multidimensional set of linear equations, through the separation of dynamic modes; and the construction of analytic and numeric models of the resulting system. These models can be used to simulate the behaviour of both single and multi material tethers across the full lifetime of a tether mission, from pretension, through re-entry burn and free body motion post burn, to re-entry.

This summary presents the work by the University of Strathclyde, SCISYS and Roke Manor Research in response to the ESA SysNova Challenge AO7891; Remote sensing with cooperative nanosats, Challenge #3 – Weather. The objective of this work was to evaluate the performance and cost of multi-agent satellite networks capable of providing data in support of severe weather monitoring.

Libration Point Orbits (LPO) and Highly Elliptical Orbits (HEO) are often selected for astrophysics and solar terrestrial missions as they offer vantage points for the observation of the Earth, the Sun and the Universe. No guidelines currently exist for LPO and HEO missions' end-of-life; however, as current and future missions are planned to be placed on these orbits, it is a critical aspect to define a sustainable strategy for their disposal, with the objective to avoid interference with protected regions.
