NASA has been working to better understand our home planet from the unique vantage point of space since the first TIROS satellites launched in the 1960s. Today, with more than two dozen Earth-observing satellites and instruments, it’s clearer than ever that our planet is an interconnected system.

The Surface Water and Ocean Topography mission offers the first taste of the detailed perspectives of Earth’s surface water that its cutting-edge instruments will be able to capture.

The end-of-winter sea ice extent in March 2023 was the fifth lowest in the satellite record.

Observations from space show that the rate of sea level rise is increasing. Knowing where and how much rise is happening can help coastal planners prepare for future hazards.

The long-term trend for sea ice in the south is still flat, while the global trend points downward.

NISAR will feature the most advanced radar system ever launched on a NASA science mission and will help us study natural hazards, melting sea ice, groundwater supply, and more.

A pilot project has estimated emissions and removals of carbon dioxide in individual nations using satellite measurements.

With the help of artificial intelligence and high-resolution satellite images, scientists mapped almost 10 billion individual trees in Africa’s drylands to assess the amount of carbon stored outside of the continent’s dense tropical forests. Having an accurate tree carbon estimate is essential for... Read More

One of the largest water bodies on the Tibetan Plateau has been growing even larger in recent decades.

Dignitaries from the U.S. and Indian space agencies, along with members of the media, were invited to see NISAR’s science payload in a Jet Propulsion Laboratory clean room.

La temperatura promedio de la superficie de la Tierra en 2022 empató con 2015 como la quinta más cálida registrada, según un análisis de la NASA. Continuando con la tendencia del calentamiento a largo plazo del planeta, las temperaturas globales en 2022 estuvieron 0,89 grados centígrados (1,6... Read More

Earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis by NASA. Continuing the planet's long-term warming trend, global temperatures in 2022 were 1.6 degrees Fahrenheit (0.89 degrees Celsius) above the average for NASA's... Read More

What can hidden motions underground tell us about earthquakes, eruptions, and even climate change? NASA scientists are using data gathered 400 miles above Earth to find out.

Climate researchers from NASA and the National Oceanic and Atmospheric Administration (NOAA) will release their annual assessments of global temperatures and discuss the major climate trends of 2022 during a media briefing at 11 a.m. EST Thursday, Jan. 12.
