“Sea level rise is one of the most visible signatures of our changing climate, and rising seas have profound impacts on our nation, our economy and all of humanity,” said Michael Freilich, director of NASA’s Earth Science Division. “By combining space-borne direct measurements of sea level with a host of other measurements from satellites and sensors in the oceans themselves, NASA scientists are not only tracking changes in ocean heights but are also determining the reasons for those changes.”
“Space Debris are defunct objects in space, including old space vehicles (such as satellites or rocket stages) or fragments from collisions. Space debris can cause great damage to functional space ships and satellites. Thus detection of space debris and prediction of their orbital paths are essential for today’s operation of space missions. The talk shows the Python-based infrastructures BACARDI for gathering and storing space debris data from sensors and Skynet for high-throughput data processing and orbital collision detection.”
“What we’re seeing in President Obama’s Executive Order is a major proof point of the importance of high-end computer technology in bolstering and redefining national competitiveness. In the past, a country’s competitiveness and global power was defined by economic growth and defense capabilities. But now we’re seeing the advent of actionable technological insight—especially derived from the power of big data—becoming a factor of a country’s power.”
NASA reports that it’s newly upgraded Pleiades supercomputer ranks number 11 on the July 2015 TOP500 list of the most powerful supercomputers. And while the LINPACK computing power of Pleiades jumped nearly 21 percent, its ranking at number 5 on the new HPCG benchmark list reflects its ability to tackle real world applications.
Astronomers Erika Nesvold (UMBC) and Marc Kuchner (NASA Goddard) essentially created a virtual Beta Pictoris in the computer and watched it evolve over millions of years. It is the first full 3-D model of a debris disk where scientists can watch the development of asymmetric features formed by planets, like warps and eccentric rings, and also track collisions among the particles at the same time.
“Pleiades, one of the world’s most powerful supercomputers, represents NASA’s state-of-the-art technology for meeting the agency’s supercomputing requirements, enabling NASA scientists and engineers to conduct modeling and simulation for NASA missions. Powered by Lustre, this distributed-memory SGI ICE cluster is connected with InfiniBand in a dual-plane hypercube technology.”
