Impact Risk in LEO as a result of the Increase of Nano and Micro-Satellites

Low Earth orbit (LEO) is experiencing a renaissance thanks to increasing commercialisation of space. The opportunities provided by small satellites are enabling diminutive companies and startups, in particular, to make a significant impact on the space economy. Small satellites have played a vital role in this revolution and they have a unique ability to bring around new products and services at short timescales and for relatively low-cost.

Design for Removal: How to design S/C to support active debris removal if uncontrolled

The population of non-operational objects in the space environment is raising, increasing concern about the safety of operations for current and future space activities. In this respect, space agencies and in particular ESA with its ESA/ADMIN/IPOL (2014) have established policies to mitigate space debris creation. Please refer to the compendium of space debris mitigation standards adopted by states and international organizations, [RD.5], for additional information. This basically implies that satellites in LEO and GEO shall perform an End Of Life (EOL) disposal with a reliability of 90%.

Impact of Low Earth Orbit Observations on Tropospheric Composition Analysis and Forecast

The ISOTROP project was a response to the ESA ITT "Impact of Spaceborne Observations on Tropospheric Composition Analysis and Forecast", AO/1- 6845/11/NL/AF. The general aim is to assess the benefit of the LEO+GEO satellite system for the understanding of local to regional scale tropospheric composition with a focus on Europe. The ISOTROP consortium involved researchers from the European institutes CNRS-GAME, TNO, NILU, FMI, and was led by KNMI.
