- 12.31.12 - Tracking Hurricanes with GEOS-5
- The GEOS-5 atmospheric model and assimilation analyses are used every day to generate 5-day weather forecasts. One view of GEOS-5 performance comes from forecasts of two of 2012's most destructive hurricanes: Isaac and Sandy.
- 12.12.12 – Where No Musician Has Gone Before
- Combining magnetic field data collected by NASA's Voyager 1 spacecraft with computer modeling techniques to reproduce the sounds of ancient musical instruments, Domenico Vicinanza and the ASTRA project created music played in the NASA booth at the international supercomputing conference (SC12) in November.
- 12.11.12 – Giving Rocket Science a Boost
- As NASA pours both its brainpower and supercomputing power into the new Space Launch System, NASA Advanced Supercomputing modeling and simulation experts remind us that it really is rocket science.
- 12.05.12 – Revolutionizing Rotorcraft Design with CFD
- NASA Advanced Supercomputing fundamental aeronautics researcher Neal Chaderjian is developing physics-based CFD tools to enhance the predictive accuracy of rotocraft flow fields.
- 11.21.12 – Ocean Currents Play a Role in Predicting Extent of Arctic Sea Ice
- Combining models and observations, MIT researchers have discovered that feedback between sea ice and ocean improves Arctic ice extent forecast. Their model-observation synthesis employs NASA's Pleiades supercomputer.
- 11.08.12 - Climate Likely to Be on Hotter Side of Projections
- A new NASA-funded study finds climate model projections that show a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise. The study included data from the Modern-Era Retrospective Analysis for Research and Applications (MERRA) run at the NASA Center for Climate Simulation.
- 10.01.12 - The Cosmological Supercomputer
- The Bolshoi simulation evolves the universe all over again using 14,000 central processing units on NASA's Pleiades supercomputer.
- 09.27.12 - Simulations Uncover 'Flashy' Secrets of Merging Black Holes
- Einstein theorized that massive objects produce gravity distortions when they interact. Astronomers have so far found only indirect evidence of these disturbances, but some think that this discovery is just a few years away.
- 09.25.12 – NASA Earth Exchange: Meet Up in the NEX World
- The NASA Earth Exchange (NEX) is a unique collaborative workspace where Earth scientists can join forces, make new discoveries, and share knowledge to gain a better understanding of our planet.
- 07.31.12 - Simulated Nature Runs Its Course
- A NASA Goddard climate model called GEOS-5 revisited the extraordinary 2005 Atlantic hurricane season as part of a gigantic two-year simulation run on Goddard’s Discover supercomputer.
- 05.24.12 - Paint by Particle
- NASA models and supercomputing have created a colorful new view of aerosol movement. The simulation took several weeks to process on a NASA Center for Climate Simulation supercomputer.
- 04.09.12 - NASA Views Our Perpetual Ocean
- Tens of thousands of ocean currents are captured in a new scientific visualization created by NASA's Goddard Space Flight Center from model-data syntheses made possible by high-end computing resources at NASA's Ames Research Center.
- 03.19.12 - Engineers Enlist Weather Model to Optimize Offshore Wind Plan
- Using a sophisticated weather model, environmental engineers at Stanford University have defined optimal placement of a grid of four wind farms off the U.S. East Coast. The NASA Advanced Supercomputing (NAS) Division provided access to computational resources.
- 03.06.12 – Searching for Sister Planets
- With the help of one of NASA's largest space telescopes and its most powerful supercomputer, scientists are analyzing observational data gathered from the Kepler mission spacecraft to search the skies for Earth's sister planets.
- 02.09.12 - Cracking the Mysteries of Space Weather
- Our planet is mostly protected from solar flares, coronal mass ejections, and other space weather events by a cocoon of magnetic field called the magnetosphere. But sometimes Earth's magnetosphere "cracks" and lets space weather inside, where it can cause damage.
- 02.09.12 - Deconstructing a Mystery: What Caused Snowmaggedon?
- Using a computer model that simulates the atmosphere, NASA scientists pieced together the meteorological whodunit of 2010's 'Snowmaggedon,' which entered the history books as the snowiest winter on record for the U.S. East Coast.
- 01.12.12 - NASA Study Shows Health, Food Security Benefits From Climate Change Actions
- A new study led by a NASA Goddard Institute for Space Studies scientist highlights 14 key air pollution control measures that, if implemented, could slow the pace of global warming, improve health and boost agricultural production.
