A new era, of second generation experiments, using detectors made from enriched material is starting at present in double beta research. This allows to strongly improve the present limits on the neutrino mass. We review the present status, in particular of the HEIDELBERG‐MOSCOW experiment, by which for the first time evidence has been given that the technology of enriched HP Ge detector production can be mastered nowadays. We further explore possible future application of this technology in astrophysics, in particular dark matter search and high‐resolution c‐ray spectroscopy in future ESA and NASA satellite missions. Use of enriched73Ge detectors for the former would allow to extend the present LEP limits for spin‐interacting WIMPs considerably and use of enriched70Ge detectors in the satellite experiments would allow to drastically reduce the b‐backgrounds in these missions.
