Abstract: 
The EURD instrument has been designed to measure diffuse emission in the extreme ultraviolet (350-1100 Angstroms). This new design provides an unprecedented 4-5 Angstroms spectral resolution and 200 photons/sec/cm^2/sr sensitivity after only 100 hours of observations. One of the goals of this project is to search for spectral lines of highly ionized species from the high temperature component (10^5-10^6 K) of the interstellar medium that fills the Local Bubble. It is expected that EURD will detect lines due to a thermalized hot component of the interstellar medium, and it will also provide critical diagnostics of the physical properties of this gas. With EURD data we could also detect a spectral line due to the decay of massive neutrinos as well as study oxygen lines from the upper atmosphere airglow. EURD is on board the Spanish MINISAT-01 satellite.
