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).

06.27.19 - ARMD, HEOMD, NESC, and STMD Computing Time Requests Due Jul. 20
The Aeronautics Research Mission Directorate (ARMD), the Human Exploration and Operations Mission Directorate (HEOMD), the Space Technology Mission Directorate (STMD), and the NASA Engineering and Safety Center (NESC) will select from computing time requests that are submitted to the eBooks online system by July 20 for 1-year allocation awards beginning October 1.


Visualization of Tunguska asteroid simulation
07.15.19 – Tunguska Revisited: 111-Year-Old Mystery Impact Inspires New, More Optimistic Asteroid Predictions
NASA Advanced Supercomputing (NAS) researchers modeled more than 50 million asteroid impact scenarios to reveal the most likely type of event that devastated Russia’s Tunguska region in 1908—the largest asteroid impact witnessed by modern humans. Their findings, reported in this month’s special issue of the journal Icarus, helped determine the average frequency of such events.

06.20.19 - Looking For Freshwater In All the Snowy Places
Empowered by the Discover Supercomputer at the NCCS and the Deepthought2 High-Performance Computing cluster at the University of Maryland, NASA-funded researchers are creating a tool that simulates the best way to detect snow and measure its water content from space.
Airborne observation of Greenland Ice Sheet
6.19.19 - Study Predicts More Long-Term Sea Level Rise from Greenland Ice
Greenland’s melting ice sheet could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate, according to a new modeling study run on supercomputers at NASA’s Ames Research Center and the University of Alaska Fairbanks.
