NASA introduced an Earth Crust Mapping Satellite

Soon, NASA scientists will launch a spaceborne gadget that will examine the changes in Earth’s crust with a closeup by using advanced radar imaging technology. This earth mapping satellite is known as NISAR (NASA-ISRO SAR), which NASA Jet Propulsion Laboratory, in collaboration with Indian Space Research Organization, built.

However, this satellite will not launch from India until 2024. This innovative space technology intends to operate for three years. It will help to better understand earth sciences like climate change, food security and how to cope with natural disasters.

NISAR is the world’s first satellite that will utilize two wavelength frequencies (L and S microwaves) in radar imaging technology to detect changes as small as 1 cm (0.4 inches) and map Earth’s crust with exceptional details.

Also, it will allow us to observe even minute details about catastrophic events like earthquakes and tsunamis along with long-term monitoring of events like ice sheet collapses, changes in ecosystems, and Earth’s crust evolution.

Another critical factor about NISAR is after every 12 days, and it will provide coverage of the entire Earth. NASA’s mission team is planning to make the data available for the public in 1-2 days, and in an emergency, data can be delivered within hours.

NISAR is expected to cost $1.5 billion and become the world’s most expensive radar imaging satellite. But its cost can be justified by the provided important information.
