5 Ways Studying Water Will Help Us Better Understand Earth

Studying our home planet is just as powerful as exploring what’s beyond it.

Surface Water and Ocean Topography (SWOT) is a joint mission developed by NASA and the French space agency Centre National d’Études Spatiales (CNES), with contributions from the Canadian Space Agency and the UK Space Agency. It will track water on more than 90% of Earth’s surface and help communities, scientists, and researchers better understand this finite and vital resource. And it’s launching this month!

So how will SWOT help us better understand Earth? Here are 5 ways.

SWOT will address some of the most pressing climate change questions of our time.

An important part of predicting our future climate is determining at what point Earth’s ocean water slows down its absorption of the excess heat in the atmosphere and starts releasing that heat back into the air, where it could accelerate global warming. SWOT will provide crucial information about this global heat exchange between the ocean and the atmosphere, enabling researchers to test and improve future climate forecasts.

The satellite will also offer insights to improve computer models for sea level rise projections and coastal flood forecasting.

Data from SWOT will additionally help scientists, engineers, water managers, and others better monitor drought conditions in lakes and reservoirs and improve flood forecasts for rivers.

SWOT is the first satellite mission that will observe nearly all water on the planet’s surface.

SWOT will measure the height of water in Earth’s lakes, rivers, reservoirs, and the ocean, giving scientists the ability to track the movement of water around the world.

SWOT’s eye in the sky will provide a truly global view of the water on more than 90% of Earth’s surface, enriching humankind’s understanding of how the ocean reacts to and influences climate change along with what potential hazards – including floods – lie ahead in different regions of the world.

SWOT will see Earth’s water in higher definition than ever before.

Because everything is better in HD 😉, SWOT will view Earth’s ocean and freshwater bodies with unprecedented clarity compared to other satellites, much like a high-definition television delivers a picture far more detailed than older models. This means that SWOT will be able to “see” ocean features – like fronts and eddies – that are too small for current space-based instruments to detect. Those measurements will help improve researchers’ understanding of the ocean’s role in climate change.

Not only will the satellite show where – and how fast – sea level is rising, it will also reveal how coastlines around the world are changing. It will provide similar high-definition clarity for Earth’s lakes, rivers, and reservoirs, many of which remain a mystery to researchers, who aren’t able to outfit every water body with monitoring instruments.

SWOT data will be used to help make decisions about our daily lives and livelihoods.

As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough. SWOT data will be used to monitor drought conditions and improve flood forecasts, providing essential information to water management agencies, disaster preparedness agencies, universities, civil engineers, and others who need to track water in their local areas. SWOT data also will help industries, like shipping, by providing measurements of water levels along rivers, as well as ocean conditions, including tides, currents, and storm surges.

Finally … SWOT will pave the way for future Earth missions.

With its innovative technology and commitment to engaging a diverse community of people who plan to use data from the mission, SWOT is blazing a trail for future Earth-observing missions. SWOT’s data and the tools to support researchers in analyzing the information will be free and accessible. This will help to foster research and applications activities by a wide range of users, including scientists, resource managers, and others who in the past may not have had the opportunity to access this kind of information. Lessons learned from SWOT will lead to new questions and improvements for future missions, including our upcoming Earth System Observatory, a constellation of missions focused on studying key aspects of our home planet.

Get Space-Crafty with Earth Science!

It’s time to get space-crafty! (Get it?) We’re getting ready to launch Landsat 9 into space this fall, and we want to know, how does Landsat inspire you?

For nearly 50 years, Landsat satellites have been collecting important data and taking beautiful images of Earth, as a partnership between NASA and the U.S. Geological Survey. Scientists and policy makers alike use this data to understand climate change, deforestation, the growth of cities, and so much more.

In celebration of the Landsat 9 launch in September, we are calling all crafters to create space-crafts inspired by your favorite Landsat image! From watercolor paintings to needlework to frosted cakes, let your creativity flow and show us how you see Landsat images.

Post a picture of your craft on Instagram, Twitter or Facebook with the hashtag #LandsatCraft. We will spotlight some on social media!

For a little inspiration, here are some #LandsatCraft examples from some of the people who work with Landsat:

“Looking through the Visible Earth Landsat gallery for inspiration, I saw the Landsat Image Mosaic of Antarctica (LIMA) and knew immediately what I had to do -- recreate it in a mosaic of my own. LIMA is a composite of more than 1,000 cloud-free Landsat 7 images of Antarctica, and when it was released in 2007 it was our first high resolution, true-color look at the icy continent.” – Kate Ramsayer, NASA Landsat Communications Coordinator

“I love embroidering satellite imagery and NASA data. For Landsat, I wanted something with lots of straight lines -- much easier to stitch! -- and crop fields like these fit the bill. It’s amazing how clearly we can see the influence of human activities in satellite imagery like this. It’s a constant reminder of the effect we have on our home planet.” – Katy Mersmann, Earth Science Social Media Lead

“We didn’t have the discipline or the organizational skills to do any of the really, really fancy images, like Lena Delta, so we chose Garden City, Kansas in 1972. We added a model of Landsat 1, too.” – Ryan Fitzgibbons, Earth Science Producer, and Charles Fitzgibbons, Age 8

"I was inspired by this Landsat image which demonstrates how we can use satellite imagery to remotely monitor cover crop performance, a sustainable farming practice that promotes soil health. Since I began working with NASA Harvest, NASA's Food Security and Agriculture Program, I've come to understand the critical importance of conservation agriculture and resilient farmlands in support of a food secure future for all, especially in the face of a changing climate." – Mary Mitkish, NASA Harvest Communications Lead

“I chose particular ingredients that represent the Landsat qualities that we celebrate:

The base spirit is gin because Landsat data is clean and precise. Vermouth represents our foreign collaborators. Using both lemon and lime juices signifies the diverse uses of the data. The ginger is for the land we study. The apple, well, because it’s American. The club soda makes it a long drink, for the long data record.” – Matthew Radcliff, NASA Landsat Producer

“Last year for the 50th Earth Day, I created this poster, inspired by our views of river deltas -- many captured by Landsat satellites -- which are particularly beautiful and evocative of water coursing through our land like a circulation system of nature. In 2000, Landsat 7 took one of my favorite images of the Lena Delta, which is the basis for this art.” – Jenny Mottar, Art Director for NASA Science

Are you feeling inspired to create yet? We’re so excited to see your #LandsatCraft projects! Follow NASA Earth on Twitter, Facebook, and Instagram to see if your art is shared!

Moonbound: One Year Since Artemis I

On this day last year, the Artemis I rocket and spacecraft lit up the sky and embarked on the revolutionary mission to the Moon and back. The first integrated flight test of the rocket and spacecraft continued for 25.5 days, validating NASA’s deep exploration systems and setting the stage for humanity’s return to the lunar surface.

On Nov. 16, 2022, the Space Launch System (SLS) rocket met or exceeded all expectations during its debut launch on Artemis I. The twin solid rocket booster motors responsible for producing more than 7 million pounds of thrust at liftoff reached their performance target, helping SLS and the Orion spacecraft reach a speed of about 4,000 mph in just over two minutes before the boosters separated.

Quite a few payloads caught a ride aboard the Orion spacecraft on the Artemis I mission: In addition to a number of small scientific satellites called CubeSats, a manikin named Commander Moonikin Campos sat in the commander’s seat. A Snoopy doll served as a zero-gravity indicator — something that floats inside the spacecraft to demonstrate microgravity. 

During the mission, Orion performed two lunar flybys, coming within 80 miles of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles from our home planet, more than 1,000 times farther than where the International Space Station orbits Earth. This surpassed the record for distance traveled by a spacecraft designed to carry humans, previously set during Apollo 13.

The Orion spacecraft arrived back home to planet Earth on Dec. 11, 2022. During re-entry, Orion endured temperatures about half as hot as the surface of the Sun at about 5,000 degrees Fahrenheit. Within about 20 minutes, Orion slowed from nearly 25,000 mph to about 20 mph for its parachute-assisted splashdown. 

Recovery teams successfully retrieved the spacecraft and delivered it back to NASA’s Kennedy Space Center for de-servicing operations, which included removing the payloads (like Snoopy and Commander Moonikin Campos) and analyzing the heat shield.  

With the Artemis I mission under our belt, we look ahead to Artemis II — our first crewed mission to the Moon in over 50 years. Four astronauts will fly around the Moon inside Orion, practicing piloting the spacecraft and validating the spacecraft’s life support systems. The Artemis II crew includes: NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA astronaut Jeremy Hansen. 

As we look ahead to Artemis II, we build upon the incredible success of the Artemis I mission and recognize the hard work and achievements of the entire Artemis team. Go Artemis!
