Survey the World's Water
How much water sloshes around in Earth’s lakes, rivers, and oceans? And how does that figure change over time? The upcoming Surface Water and Ocean Topography (SWOT) mission plans to find out. Targeting a late-2022 launch date, this SUV-size satellite will measure the height of Earth’s water. SWOT will help researchers understand and track the volume and location of water – a finite resource – around the world, making NASA’s…

Stratosphere shrinkers
Thinning indicates a profound impact of humans and could affect satellites and GPS Humanity’s enormous emissions of greenhouse gases are shrinking the stratosphere, a new study has revealed. The thickness of the atmospheric layer has contracted by 400 metres since the 1980s, the researchers found and will thin by about another kilometre by 2080 without major cuts in emissions. The changes have the potential to affect satellite operations, the GPS…
