Super computer is playing a vita role in exploring the inner as well as outer universe.


Here are Five things to know about NASA supercomputing research projects:

1. Supercomputers lead to environmentally friendly, all-electric plane designs



NASA's X-57 Maxwell is a revolutionary experimental airplane designed to demonstrate that an all-electric airplane can be more efficient, quieter, and more environmentally friendly than those powered by traditional gas piston engines. The X-57 uses a unique distributed electric propulsion, or DEP, system that includes 12 electrically powered propellers for additional lift at takeoff and landing.


NASA created a computational fluid dynamics, or CFD, aerodynamic database for a piloted simulator, airworthiness assessments, and safety analyses prior to the first flight. Aerospace engineers at NASA’s Langley Research Center in Hampton, Virginia are using the Pleiades supercomputer at the NASA Advanced Supercomputing, or NAS, facility at the agency's Ames Research Center in California's Silicon Valley to perform their CFD. This year the researchers focused their simulations on determining the impacts of DEP motor failures, which are used in simulators so test pilots can prepare for the possibility of system failures during real X-57 flight tests. This work will directly impact flight safety during the real flight tests, and ultimately the life of the pilot.

2. Massive simulations help keep astronauts safe



With nasa's first artemis mission scheduled to take off in 2022, engineers and researchers across the agency are steadily working to ensure the safety and success of the missions that will use nasa's space launch system, or sls, and the orion crew module.

To support upcoming missions from launch complex 39b at nasa's kennedy space center, engineers at nasa ames developed a new cfd approach to accurately simulate the launch environment, including its water-based sound suppression system, to estimate acoustic loads during liftoff -- a necessary step for the design and certification of the agency's vehicles and flight instruments.

concurrently, engineers at nasa's marshall space flight center in huntsville, alabama are running simulations on nasa supercomputers to better understand and predict non-acoustic aspects of the sls liftoff environment -- specifically, how the solid rocket boosters will interact with the water-based sound suppression system at ignition, which may create large, but short-lived, pressure forces.

Orion also has a wide range of safety systems, including a state-of-the-art launch abort system that can quickly pull astronauts to safety in the event of an emergency. a team at nas is using detailed turbulence-resolving simulations to understand how the system's abort motor firing can impact the crew module for abort scenarios that were not flight tested -- for example, a high-altitude, near-hypersonic abort scenario at the edge of earth's atmosphere.

3. Drought and flood forecasts help responses to water and food security crises


For millions of Africans, droughts and floods not only affect their lives, but they themselves as they run out of water and food. Authorities and aid organizations rely on early warning systems to help residents cope with extreme or protracted events.

Water scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland combined computer models and observational data with NASA's Water Predictive Analytics System (NHyFAS).

NHYFAS makes monthly drought and flood forecasts for Africa and the Middle East. NHyFAS, which runs multiple land surface models in an ensemble, requires the processing power of the Discover supercomputer operated by NASA Goddard's NASA Climate Simulation Center (NCCS). From NCCS DataPortal, NHyFAS forecast products will be sent directly to food security analysts working with a network of US agencies for the international development of an early hunger warning system to notify humanitarian responses.

4. Innovations in computing are expanding research and improving collaboration  


These innovations include NASA's modular supercomputing facility managed by Ames' NAS division. It uses an environmentally friendly and scalable design to achieve energy efficiency and cost savings. The NAS department is also a tool to expand machine learning research to improve the processing of large amounts of data from ground and space-based equipment, investigate advances in areas such as pattern recognition and anomaly detection, and support NASA. Is developing. Do unprecedented things in future missions.

Another innovative system is the Science Managed Cloud Environment (SMCE), recently developed by NASA Goddard engineers. The SMCE team and collaborators have developed the NASA Earth Information System (EIS). It's a flexible and responsive computing feature that leverages the versatility of Amazon Web Services Cloud to create a collaborative, open scientific environment. EIS is a pilot study focused on fire, freshwater, and sea level changes, providing analyzable products that scientists and laymen alike can use.
