The ICESat-2 laser altimeter data provide height measurements of every 2.3 feet (70 centimeters) along the ground path. The data provide precise measurements of the ice sheet height, ice floes, forest canopies, rivers and lakes and surface topography, and shallow water bathymetry.
ASA and researchers from around the world will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union (AGU), Dec. 1-17, held virtually this year.
Researchers from the NASA Center for Climate Simulation (NCCS), its parent Computational Information & Sciences and Technology Office (CISTO), NASA Goddard Space Flight Center, and university partner organizations are participating in the Scientific Program at the 2020 American Geophysical Union (AGU) Fall Meeting, being held online 1–17 Dec 2020.
A joint U.S.-European satellite, built to monitor global sea levels, lifted off on a SpaceX Falcon 9 rocket from Vandenberg Air Force Base just after 9 a.m. Pacific Time on November 21, 2020.
One of our recent geomagnetic predictions is the continuous westward expansion of the South Atlantic Anomaly (SAA), an area at the Earth’s surface where the geomagnetic field intensity is exceptionally low and stretches from southern Africa, across the southern Atlantic and South America, to the eastern Pacific.
The NASA Center for Climate Simulation (NCCS) and NASA Goddard Space Flight Center partners will highlight their recent advances during SC20, the International Conference for High Performance Computing, Networking, Storage, and Analysis being held virtually November 9–19, 2020.
From assessing COVID-19’s global impacts to helping NASA return humans to the Moon to searching the cosmos for new exoplanets, researchers from across NASA, with university and industry partners, will highlight their latest advances, enabled by the agency’s supercomputers, at SC20—the International Conference for High Performance Computing.
Knowing the precise location of a satellite in space is critical for determining sea surface height and, through this, the rate of global mean sea level rise.
Annapolis, Maryland; Norfolk, Virginia; and Miami were originally built and mapped to provide enough protection against flooding, but sea level rise has caused that buffer to shrink.
With a small nudge to a satellite’s orbit, scientists will soon have simultaneous laser and radar measurements of ice, providing new insights into Earth’s frozen regions.
The Sentinel 6/Freilich ocean radar altimeter satellite is undergoing system and environment testing at a test facility near Munich, Germany in preparation for launch later this year. Once in orbit, each satellite will collect sea level measurements down to the centimeter for 90% of the world's oceans from the TOPEX reference orbit.
NASA Goddard and university scientists built high-resolution models of the Moon’s gravity field using NCCS supercomputers and data from GRAIL and LRO, revealing detailed structure of the lunar crust.
Fifty years ago, on April 22, 1970, people around the world marked the first Earth Day. Thousands gathered to raise awareness about the importance of protecting our beautiful planet for future generations.
As the world observes the 50th anniversary of Earth Day on Wednesday, April 22, NASA is highlighting the agency’s many contributions to sustaining and improving our home planet’s environment...
Across NASA’s many missions, thousands of scientists, engineers, and other experts and professionals all over the country are doing what they do best, but now from home offices and via video conferencing. With most personnel supporting missions remotely to keep onsite staff at a minimal level in response to COVID-19, the Agency is moving ahead strongly with everything from space exploration to using our technology and innovation to help inform policy makers.
Goddard has canceled all non-mission-essential visits to its facilities. Goddard also is closing its Visitor Centers at Greenbelt and at Wallops Flight Facility, Virginia.
