Watching Water in the West

If you’ve eaten a piece of fruit, a vegetable, or a handful of nuts in the past week, it’s very likely they all came from “America’s Salad Bowl.” California’s Central Valley and Central Coast is where more than one-third of all vegetables in the U.S. are grown––and two-thirds of our fruits and nuts.

Keeping this area fertile takes a lot of water, and we provide farmers with NASA data that helps them manage increasingly scarce supplies. Working with farmers and conservation groups, we developed a new website called OpenET to transform how water is managed in the West! It covers 17 western U.S. states, putting satellite and other Earth science data into their hands. The website gives them daily and monthly views of water usage, down to the resolution of a single field of vegetables.

The ET in OpenET doesn’t stand for extraterrestrial, but “evapotranspiration.” Evapotranspiration is a measurement that farmers can use to estimate the amount of water being used by their fields and crops. This water will usually need to be replaced through irrigation or rainfall.

We work closely with partners and people around the world, connecting them with NASA Earth data to solve our planet’s most pressing issues.

Earth: Our Oasis in Space

image

Earth: It’s our oasis in space, the one place we know that harbors life. That makes it a weird place – so far, we haven’t found life anywhere else in the solar system…or beyond. We study our home planet and its delicate balance of water, atmosphere and comfortable temperatures from space, the air, the ocean and the ground.

image

To celebrate our home, we want to see what you love about our planet. Share a picture, or several, of Earth with #PictureEarth on social media. In return, we’ll share some of our best views of our home, like this one taken from a million miles away by the Earth Polychromatic Imaging Camera (yes, it’s EPIC).

From a DC-8 research plane flying just 1500 feet above Antarctic sea ice, we saw a massive iceberg newly calved off Pine Island Glacier. This is one in a series of large icebergs Pine Island has lost in the last few years – the glacier is one of the fastest melting in Antarctica.

image

It’s not just planes. We also saw the giant iceberg, known as B-46, from space. Landsat 8 tracked B-46’s progress after it broke off from Pine Island Glacier and began the journey northward, where it began to break apart and melt into the ocean.

image

Speaking of change, we’ve been launching Earth-observing satellites since 1958. In that time, we’ve seen some major changes. Cutting through soft, sandy soil on its journey to the Bay of Bengal, the Padma River in Bangladesh dances across the landscape in this time-lapse of 30 years’ worth of Landsat images.

Our space-based view of Earth helps us track other natural activities, too. With both a daytime and nighttime view, the Aqua satellite and the Suomi NPP satellite helped us see where wildfires were burning in California, while also tracking burn scars and smoke plumes..

Astronauts have an out-of-this-world view of Earth, literally. A camera mounted on the International Space Station captured this image of Hurricane Florence after it intensified to Category 4.

It’s not just missions studying Earth that capture views of our home planet. Parker Solar Probe turned back and looked at our home planet while en route to the Sun. Earth is the bright, round object.
