Modeling the Hawaiian Shoreline

NeRD

NASA/Lisa Tanh, Matilda Anokye, Ian Lee, Connor Racette The island of Hawai’i and surrounding waters glow in unusual shades in this 2022 model made through NASA DEVELOP. The model was created to help the County of Hawai’i in their shoreline setback plan. The image shows areas of high flood risk (blue), as well as sea surface temperatures. Orange in the west indicates high temperatures, while red in the east represents low temperatures. NASA DEVELOP projects bridge the gap between NASA’s Earth science data and society, addressing environmental concerns and enhancing…

Satellite images of Rafah illustrate Palestinians fleeing the city

NeRD

Satellite images taken earlier this month offer a spaceborne perspective of the ongoing Israel-Hamas war. They include scenes such as a before-and-after sequence that illustrates Palestinian civilians fleeing Rafah, a view of damaged buildings in the region and conglomerates of Israeli hardware.  For the past several months, Israeli Defense Forces (IDF) have destroyed major portions of areas in which Palestinian civilians live as a response to the Oct. 7 terrorist attack in Israel, an attack orchestrated by the radical militant group Hamas. As Reuters reported on May 14, Israel says…

Meet NASA Women Behind World’s Largest Flying Laboratory

NeRD

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s DC-8 aircraft – the world’s largest flying science laboratory – began its science missions in 1987 and since then, has flown in service of the science community over places like Antarctica, Greenland, and Thailand. Aircraft like the DC-8 have enabled scientists to ask questions about life on Earth and explore them in a way that only NASA’s Airborne Science program can make happen. After 37 years, the DC-8 will retire to Idaho State University, where it will serve…

Next-gen satellites will paint a clearer picture of a changing Earth

NeRD

Thanks to next-generation satellite systems scientists have in place, like the National Oceanic and Atmospheric Administration’s GOES-R series, scientists are able to get high-definition images of Earth faster than ever before. This is data that helps paint a full picture of our planet; the satellites can be thought of as in collaboration with one another, using special tools to make measurements and take observations that would otherwise be nearly impossible to perform from the ground directly. Yet, as our climate continues to change at a rapid rate due to human…

NASA-Led Study Provides New Global Accounting of Earth’s Rivers

NeRD

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Colorado River supplies water to more than 40 million people as it snakes through seven U.S. states, including the part of southeastern Utah seen in this photo snapped by an astronaut aboard the International Space Station. The Colorado basin was identified in a NASA-led study as a region experiencing intense human water use. NASA The novel approach to estimating river water storage and discharge also identifies regions marked by ‘fingerprints’ of intense water use. A study led by…

NASA’s ORCA, AirHARP Projects Paved Way for PACE to Reach Space

NeRD

It took the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission just 13 minutes to reach low-Earth orbit from Cape Canaveral Space Force Station in February 2024. It took a network of scientists at NASA and research institutions around the world more than 20 years to carefully craft and test the novel instruments that allow PACE to study the ocean and atmosphere with unprecedented clarity. In the early 2000s, a team of scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, prototyped the Ocean Radiometer for Carbon Assessment (ORCA) instrument,…

People there are also enlisting the aid of nature’s most prolific engineers – beavers. Using NASA-provided grants, two open-source programs from Boise State University in Idaho and Utah State University in Logan are making it possible for ranchers, land…

AI for Earth: How NASA’s Artificial Intelligence and Open Science Efforts Combat Climate Change

NeRD

4 min read AI for Earth: How NASA’s Artificial Intelligence and Open Science Efforts Combat Climate Change Lights brighten the night sky in this image of Europe, including Poland, taken from the International Space Station. NASA As extreme weather events increase around the world due to climate change, the need for further research into our warming planet has increased as well. For NASA, climate research involves not only conducting studies of these events, but also empowering outside researchers to do the same. The artificial intelligence (AI) efforts spearheaded by the…

SWOT Satellite Helps Gauge the Depth of Death Valley’s Temporary Lake

NeRD

Water depths in Death Valley’s temporary lake ranged between about 3 feet (or 1 meter, shown in dark blue) to less than 1.5 feet (0.5 meters, light yellow) from February through early March. By measuring water levels from space, SWOT enabled research to calculate the depth. NASA/JPL-Caltech Data from the international Surface Water and Ocean Topography mission helped researchers to calculate the depth of water in this transient freshwater body. California’s Death Valley, the driest place in North America, has hosted an ephemeral lake since late 2023. A NASA-led analysis…
