DASS is currently undergoing development and testing to make it operational in the coming years after a complete constellation of DASS-equipped satellites is launched.

Nasa search and rescue mission manager David Affens said that DASS would be able to almost instantaneously detect and locate distress signals generated by 406MHz beacons installed on aircraft and vessels or carried by individuals.

The satellite-based instruments used to relay the emergency signals will be installed on the US military’s global positioning system (GPS) to improve efficiency.

The station will be able to produce its own electricity and take surface samples, which will the be sent back to Earth for further study.
