12.01.20 - NJIT Solar Physicists Take Spotlight at NASA's Int'l Supercomputing Conference
New Jersey Institute of Technology (NJIT) heliophysicists who have developed new ways to forecast explosive events from the interior of the Sun recently captured the attention of international space and computer science communities with their exhibit featured at NASA’s Virtual SC20 Supercomputing Conference. Their research uses thousands of computing hours on NASA's Pleiades supercomputer.
12.01.20 - NCCS, CISTO, and Partners Present Advances at Virtual AGU Fall Meeting
Researchers from the NASA Center for Climate Simulation (NCCS), its parent Computational Information and Sciences and Technology Office (CISTO), NASA Goddard Space Flight Center (GSFC), and university partner organizations are participating in the Scientific Program at the 2020 American Geophysical Union (AGU) Fall Meeting, being held online 1–17 December 2020.

11.19.20 Simulating NASA's Rocket Launch for Artemis Moon Missions
The Launch Ascent and Vehicle Aerodynamics (LAVA) team at NASA’s Ames Research Center runs high-fidelity, multiphase launch environment simulations to better understand the ignition overpressure and acoustic pressure waves that occur during launch and how they affect the Space Launch System rocket and Orion spacecraft, to help ensure when launch day arrives, everything goes smoothly.

11.19.20 - Tree Census from Space: Quantifying Woody Biomass Using Machine Learning
Combining 50-centimeter scale satellite data with computing resources from the NCCS and National Center for Supercomputing Applications, NASA Goddard Space Flight Center’s Compton Tucker and collaborators mapped a surprising 1.8 billion trees across West Africa and determined the area of leaves within the tree crowns, which the researchers will combine with tree height calculations to accurately predict carbon in the wood of trees over vast semi-arid regions.

11.18.20 - NASA Simulations Validate Orion Safety Models for Artemis Astronauts
As part of the Artemis program, NASA’s Orion spacecraft will carry the first woman and next man to lunar orbit before they land on the Moon in 2024. An integral part of ensuring safe spaceflight is Orion’s Launch Abort System (LAS). To better understand the effects of strong vibrations generated by the abort motor’s high-speed exhaust plumes, a team at NASA Ames Research Center produced high-fidelity simulations using NASA’s Electra supercomputer.

11.17.20 - NASA Supercomputers Visualize Quieter Supersonic Flight
NASA’s X-59 Quiet SuperSonic Technology X-plane is designed to fly faster than the speed of sound without producing sonic booms. Researchers at the NASA Advanced Supercomputing (NAS) facility, in collaboration with Lockheed Martin, created a database of computational fluid dynamics simulations to verify the aircraft’s supersonic performance. The X-59 simulations are performed on the NAS facility’s Pleiades supercomputer.

11.17.20 - NASA Model Reveals How Much COVID-related Pollution Levels Deviated from the Norm
Using computer models to generate a COVID-free 2020 for comparison, NASA researchers found that since February, pandemic restrictions have reduced global nitrogen dioxide concentrations by nearly 20%. The model simulation and machine learning analysis took place at the NCCS.
