Chasing Satellites With Jacques Cousteau

Leaving from Nassau on a Tuesday night in late August 1975, Jacques Cousteau, his divers, and a team of scientists set out on the Calypso for a three-week expedition to determine if the young Landsat satellite mission could measure the depth of shallow ocean waters.

Scientists from NASA's Goddard Space Flight Center in Greenbelt, Maryland, and international collaborators demonstrated a new method for mapping the location and size of trees growing outside of forests

Mediterranean Sea At Night From Orbit

This nighttime view from the International Space Station looks across the Mediterranean Sea ringed by the coastal city lights of southeastern Europe, the Middle East and north Africa.

A small but evolving dent in Earth's magnetic field can cause big headaches for satellites.

The activity of the solid Earth - for example, volcanoes in Java, earthquakes in Japan, etc - is well understood within the context of the ~50-year-old theory of plate tectonics.

Ozone levels above the Arctic reached a record low for March, NASA researchers report. An analysis of satellite observations show that ozone levels reached their lowest point on March 12 at 205 Dobson units.

The Earth's glow blankets the horizon as the International Space Station was nearing Perth, Australia over the Indian Ocean.

Look around. Can you see the air? No?

NASA researchers have developed new satellite-based, weekly global maps of soil moisture and groundwater wetness conditions and one- to three-month U.S. forecasts of each product.

As NOAA-20 passed over the Middle East on March 8, 2020, it captured this image of dust blowing over the Persian Gulf.

Spacecraft Look Back On Our Cosmic Home

Thirty years ago, on 14 February 1990, NASA's Voyager 1 had completed its exploration of the gas giants Jupiter and Saturn and was just about to venture even farther, towards the edge of our Solar System.

Lake Guiers and the Senegal River separating the African nations of Senegal and Mauritania are pictured as the International Space Station orbited 257 miles in altitude off the Atlantic coast.

Scientists Find Iron 'Snow' In Earth's Core

The Earth's inner core is hot, under immense pressure and snow-capped, according to new research that could help scientists better understand forces that affect the entire planet.

Earth has many stories to tell, even in the dark of night.

A NASA-funded study suggests winter carbon emissions in the Arctic may be adding more carbon into the atmosphere each year than is taken up by Arctic vegetation, marking a stark reversal for a region that has captured and stored carbon for tens of thousands of years.

NASA has selected a space-based instrument under its Earth Venture Instrument (EVI) portfolio that will make observations of coastal waters to help protect ecosystem sustainability, improve resource management, and enhance economic activity.

Water is so commonplace that we often take it for granted. But too much - or too little of it - makes headlines.

Earlier in the week, NOAA's National Hurricane Center was monitoring a low-pressure system in the Gulf of Campeche that has now moved along the Texas and Louisiana coastlines, bringing heavy rainfall. On June 5, NASA used a constellation of satellites to estimate that rainfall.

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

Most people behave differently when under extreme pressure. Carbon and ice are no different.
