In this episode of We Need Water, we dive into NASA’s groundbreaking GRACE Project (Gravity Recovery and Climate Experiment), which uses satellites to monitor Earth’s freshwater resources. NASA recently released a report detailing the findings from this vital mission, revealing the state of freshwater supplies across the globe.

Our guest, Dr. Matthew Rodell, one of the study’s authors, joins us to explain how the GRACE Project works, why NASA is focused on Earth’s water resources, and what the findings mean for our planet. We’ll explore which regions are experiencing the greatest water stress, where resources are improving, and how governments use GRACE data to inform policy.

Tune in to learn how space technology is helping us better understand—and protect—our planet’s most precious resource.

Topics Covered:

1. What is the GRACE Project, and how does it work?
2. Why NASA is studying Earth’s freshwater resources
3. Key findings from the GRACE Project report
4. Implications of declining freshwater resources
5. Regions facing the greatest water stress—and areas showing improvement
6. How governments use GRACE data to inform policies
7. The future of the GRACE Project and its global impact

Matthew Rodell is a NASA researcher and author of the study of the GRACE project findings.

Cardiac Cowboys

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
