High-End Computing Program

Delivering high-end computing systems and services to NASA's aeronautics, exploration, science, and space technology missions.


If you are a NASA-sponsored scientist or engineer, computing time is available to you at the High-End Computing (HEC) Program's NASA Advanced Supercomputing (NAS) Facility and NASA Center for Climate Simulation (NCCS).

10.01.19 - SMD Using New Request Management System Starting Oct. 1
As of October 1, 2019, the Science Mission Directorate (SMD) is using the new HEC Request Management System (RMS) for requesting and managing allocations on NAS and NCCS computing resources.

10.11.19 - NCCS Hosts New Land Data Assimilation System for the National Climate Assessment
Uniting NASA Center for Climate Simulation (NCCS) computing with NASA Land Information System software, NASA Goddard Sapce Flight Center scientists built and ran a new land data assimilation system that uses multi-generational satellite observations to better estimate land surface changes including droughts and floods.

09.23.19 - Venus May Have Been Habitable Until a Mysterious Catastrophe Millions of Years Ago
In a new simulation study run at the NASA Center for Climate Simulation (NCCS), scientists make the case for how ancient Venus could have once supported life alongside oceans of liquid water, until a mysterious resurfacing event took all that away about 700 million years ago.

09.20.19 - GMAO Science Snapshot: Impacts of 2019 Boreal Forest Fires on Atmospheric Pollution
Using the NASA/Global Modeling and Assimilation Office (GMAO) numerical model GEOS and the observation-based QFED, fire emissions and transport from 2019 northern hemisphere summer Boreal fires have been analyzed and are compared with previous years. GEOS runs at the NCCS.

09.13.19 - Scientists Simulate Ancient Lunar Atmosphere at NCCS
Using NCCS computing resources, NASA Goddard Institute for Space Studies (GISS), Columbia University, University of Colorado, and NASA Langley Research Center scientists simulated an ancient lunar atmosphere that could have brought substantial amounts of water to the Moon’s poles.
Visualization of Hurricane Dorian rainfall and winds
09.05.19 - A Devastating Stall by Hurricane Dorian
As shown by satellite and model data, a remarkable slowdown led to a prolonged lashing from winds, waves, and rain that devastated Grand Bahama Island. Data sources include NASA's GEOS-5 model running at the NCCS.

08.23.19 - Hacking ICESat-2: How an Open Science Workshop Helped Scientists Wrangle Big Data
Planned for a year by 20 scientists from organizations including NASA Goddard, the University of Washington (UW), and the National Snow and Ice Data Center, the ICESat-2 Hackweek took place at UW in Seattle June 17–21, 2019. The event resulted in more scientists being interested in, and better able to take advantage of, ADAPT science cloud resources from the NCCS.
