The e.Inspector satellite is a future 12U CubeSat under development by the European Space Agency (ESA) for demonstrating on-orbit satellite servicing and space debris mitigation technologies. The spacecraft's goal is to perform a close-up inspection of a piece of space debris of European origin, possibly a Vega rocket's VESPA adapter or the PROBA-1 satellite, using visible and thermal imaging and to test multispectral image-based relative navigation. The spacecraft is being built by an Italian consortium of Politecnico di Milano, Leonardo, LeafSpace, and T4i under the ESA's General Support Technology Programme (GSTP). It is expected to launch in 2027.
