Off-earth mining will be crucial if the dream of building cities in space is to become a reality.
Two Australian satellites, feared lost after being deployed from the International Space Station, have been recovered by UNSW engineers after weeks of a fraught, and at times heart-stopping, recovery operation.
UNSW space researchers will be able to improve technology that mitigates satellite navigation interference and make satellites cheaper, thanks to almost $600,000 in new federal funding.
The final space shuttle mission could mark the start of a new era of opportunity in space for Australia, says UNSW's Australian Centre for Space Engineering Research.
Researchers have warned that GPS systems are becoming increasingly vulnerable to accidental interference or deliberate jamming, raising concerns about reliability and security.
