Latest International Water Satellite Packs an Engineering Punch

Set for a Thursday, Dec. 15 launch, the Surface Water and Ocean Topography (SWOT) satellite promises to provide an extraordinary accounting of water over much of Earth’s surface. Its measurements of fresh water and the ocean will help researchers address some of the most pressing climate questions of our time and help communities prepare for a warming world. Making […]

NASA Study: Rising Sea Level Could Exceed Estimates for U.S. Coasts

By 2050, sea level along contiguous U.S. coastlines could rise as much as 12 inches (30 centimeters) above today’s waterline, according to researchers who analyzed nearly three decades of satellite observations. The results from the NASA Sea Level Change Team could help refine near-term projections for coastal communities that are bracing for increases in both […]

Methane ‘Super-Emitters’ Mapped by NASA’s New Earth Space Mission

NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission is mapping the prevalence of key minerals in the planet’s dust-producing deserts – information that will advance our understanding of airborne dust’s effects on climate. But EMIT has demonstrated another crucial capability: detecting the presence of methane, a potent greenhouse gas. In the data EMIT has […]

NASA Study Finds Climate Extremes Affect Landslides in Surprising Ways

The results represent an early step toward developing what researchers hope will become the ability to forecast whether a slow-moving landslide will collapse. Climate change is driving more volatile precipitation patterns around the world – very dry stretches punctuated by storms that drop large amounts of rain or snow in a short amount of time. […]

DART’s Impact with Asteroid Dimorphos (Official NASA Broadcast)

Countdown to impact as NASA’s Double Asteroid Redirection Test (DART) attempts humanity’s first-ever test of planetary defense! The DART spacecraft will intentionally crash into asteroid Dimorphos at 4:14 p.m. PT on Monday, September 26, 2022 to see if kinetic force can change its orbit. Why? If this test is successful, the same technique could be […]

NASA Data on Plant ‘Sweating’ Could Help Predict Wildfire Severity

A new study uses data from the ECOSTRESS instrument aboard the space station to better understand why some parts of a wildfire burn more intensely than others. Even in drought-stricken California, not all areas face the same degree of wildfire risk. A recent study featuring data from NASA’s ECOSTRESS mission found relationships between the intensity […]

Tonga Eruption Blasted Unprecedented Amount of Water Into Stratosphere

The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, could end up temporarily warming Earth’s surface. When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in […]

Planetary Defense Exercise Uses Apophis as Hazardous Asteroid Stand-In

Over 100 participants from 18 countries – including NASA scientists and the agency’s NEOWISE mission – took part in the international exercise. Watching the skies for large asteroids that could pose a hazard to the Earth is a global endeavor. So, to test their operational readiness, the international planetary defense community will sometimes use a […]
