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).


Map of water vapor after the Hunga Tonga volcano eruption
08.11.22 - GMAO Explores Hunga Tonga Volcano Eruption and Atmospheric Rivers
NASA's Global Modeling and Assimilation Office (GMAO) used a new composition reanalysis to study water vapor from the Hunga Tonga volcano eruption and weather reanalyses to detect atmospheric rivers. The projects leveraged NASA High-End Computing resources at the NASA Center for Climate Simulation (NCCS).
Simulation of a 120-meter asteroid entering the atmosphere
08.02.22 - NAS Team Collaborates on Asteroid Impact Simulations for Planetary Defense
NASA Advanced Supercomputing (NAS) Division researchers on the Asteroid Threat Assessment Project (ATAP) at Ames Research Center play a key role in ongoing planetary defense and asteroid threat exercises conducted with governmental and international organizations. Recently, the ATAP team participated in a technical interchange meeting on Asteroid Impact Global Effects, and published a paper, “Apophis Planetary Defense Campaign.” The team runs simulations on NAS facility supercomputers to estimate the severity and likelihood of damage that could result from potential asteroid impacts on Earth.

07.22.22 - NCCS-Enabled Simulations of Massive Ancient Volcanic Eruption Show Unexpected Climate Warming
In an interdisciplinary collaboration, NASA Goddard Space Flight Center planetary and Earth scientists leveraged the Goddard Earth Observing System Chemistry-Climate Model (GEOSCCM) and the NASA Center for Climate Simulation (NCCS) to simulate an ancient, massive volcanic eruption in the Columbia River Basalt Group region of the U.S. Pacific Northwest.

07.19.22 - Aitken Leaps Over Pleiades to Become NASA’s Most Powerful Supercomputer
With its latest expansion, the Aitken supercomputer became NASA’s most powerful high-performance computing (HPC) system—surpassing the agency’s longtime HPC workhorse, Pleiades, which held the title for 14 years after its deployment in 2008. Aitken is a key resource for hundreds of researchers working on projects across all of NASA’s mission directorates, including aerospace engineers at the NAS facility who contribute to the Artemis Program by simulating the launch environment at Kennedy Space Center.
