NISAR radar maps Antarctic ice pattern
NDTV··25 Jul
NASA-ISRO NISAR mission L-band radar captured a hummingbird-like pattern beneath ice at Nunatak Zaterjavshijsja in East Antarctica. Public data access began from July 20. Radar sees through ice unlike optical imagery, revealing subsurface features hidden from conventional satellites. The release marks an early science win for the joint mission. NISAR L-band radar captured a hummingbird-like pattern in East Antarctica.
