How NASA Decodes the Secrets of the Arctic
Since 2015, scientists with NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) project have been studying how climate change is affecting Arctic and boreal regions. The team is studying permafrost thaw, changes […]
Operation Earth: Wildfires
When it comes to wildfires, NASA leverages its unique perspective from space to formulate predictive analysis, contribute to active fire monitoring, and assist in post-fire recovery and rehabilitation. Using 2017’s […]
NASA Explorers: Frozen Worlds
You have to start somewhere when looking for life away from Earth. Many NASA Explorers look for places with water ice, including distant moons like Enceladus and Europa. This week, […]
NASA Explorers: Glacial Pace
NASA Explorers study Earth’s glaciers and ice sheets more than almost any other part of the cryosphere. As they melt and change, glaciers and ice sheets dramatically affect sea level […]
NASA Explorers: The Snow Below
Snow is one part of the cryosphere that many of us have actually encountered, but it also plays a crucial role in regulating Earth’s climate. Through decades of remote sensing, […]
How Do We Know Earth Is Changing?
Scientists can use new and old pictures to keep track of Earth’s changes over time. Since Earth is where we live – and it’s the only planet we know of […]
NASA Explorers: High Mountain Glaciers
They’re rivers of ice, slowly flowing down the sides of mountains, and they currently have an outsized role in sea level rise. NASA Explorers is taking us high into the […]
NASA Explorers: Orbiting Laboratory
Things behave a bit differently aboard the International Space Station, thanks to microgravity. Sure, floating looks like fun, but it could also unlock new scientific discoveries. Microgravity makes the station […]
NASA Explorers: The New Normal
As the planet warms, fire seasons burn year-round and more areas are becoming flammable. NASA Explorers are studying how fires are changing with the climate and tracking how landscapes change […]
How Much Water Is on Earth?
Earth is special because it has so much water. It’s in the ground, forms big oceans, and it’s in our atmosphere. It’s also in living things.
NASA Explorers: Follow that Plume!
Chasing smoke is a round-the-clock business. Wildfire smoke can travel long distances and over several days, so NASA Explorers with the Fire Influence on Regional to Global Environments and Air […]

NASA Explorers: Chasing Clouds
“Earth science is a subject far too big for one country, one agency, to tackle all by itself.” So NASA Explorers team up with researchers from around the country and […]
NASA Explorers: Flying Alaskan Glaciers
Flying low over some of the most dramatic landscapes on the planet, a cadre of scientists and pilots have been measuring changes in Alaskan glaciers as part of NASA’s Operation […]
NASA Explorers: The Carbon Problem
In the Arctic, fires are a natural part of the ecosystem. But as the climate changes, fires are burning longer and hotter, releasing long-buried carbon from the soil. NASA Explorers […]
NASA Explorers: Final Approach
In the pre-dawn hours of a late October day, a satellite and an airplane joined forces over the frigid Weddell Sea, taking simultaneous measurements of drifting sea ice. It was […]
NASA Explorers: The Big Thaw
NASA Explorers is a new digital series that takes you inside the space agency and follows the pioneers, risk-takers and experts at the front line of exploration. Season 1, “Cryosphere,” […]
NASA Explorers: Seeing Through Smoke
To understand fires on Earth, you need a broad view — spanning from the poles to the equator and looking from high above the planet to down deep under the […]
NASA Explorers: A Year in Fire
We live in a “new normal.” Large fires burn in the Arctic, sending carbon around the globe. Fire seasons in the American West burn longer and hotter. To put it […]
Rising Waters Sea Level: NASA Infrastructure
A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure, particularly at Langley Research Center in Hampton, Virginia, and Ames Research Center […]
What Is the Greenhouse Effect?
Earth is a comfortable place for living things. It’s just the right temperatures for plants and animals – including humans – to thrive. Why is Earth so special?
Why Observe: Tree Height
“Why Observe?: Tree Height” explores surface height measurement missions and the role that citizen science can play within the scientific community.
Welcome to the Ionosphere
Learn about the features of the ionosphere! This little-explored region exists between space and Earth. It is home to the aurora, the international space station, a variety of satellites, and […]
Why Observe: Land Cover
Why do scientists use land cover observations from satellites, and why do they need help from citizen scientists? Find out the answer to these questions in Why Observe?: Land Cover […]
Down to Earth: The Miracle Planet
In this episode of “Down to Earth: Conversations,” Suni and Adrien discuss protecting our planet’s environment and give their closing thoughts on their conversation.
Temperature Record 101: How We Know What We Know about Climate Change
NASA’s global temperature analysis, takes in millions of observations from instruments on weather stations, ships and ocean buoys, and Antarctic research stations, to determine how much warmer or cooler Earth […]
Ocean Worlds: The Search for Life
Astrobiology, our search for life beyond Earth, is a search for planets, dwarf planets, and moons that harbor substantial liquid water. We call these places “ocean worlds.”
Ozone 101: What Is the Ozone Hole
Ozone 101 is the first in a series of explainer videos outlining the fundamentals of popular Earth science topics. Let’s back up to the basics and understand what caused the […]
Carbon Crisis
From space, sky, sea, and land, NASA provides detailed climate data and research to the world.
Down to Earth: Changing Your Perspective
In this episode of Down to Earth, veteran astronaut Sunita ‘Suni’ Williams sits down with environmental studies student, Adrien Prouty, to discuss her previous missions, and what it was like […]
