Planning for a Smooth Landing on Mars
A U.S. mission to land astronauts on the surface of Mars will be unlike any other extraterrestrial landing ever undertaken by NASA. Although the space agency has successfully landed nine robotic missions on Mars since its first surface missions in 1976 with the Viking Project, safely bringing humans to Mars…

Exascale’s New Frontier: Combustion-Pele
PI: Jacqueline Chen, Sandia National Laboratories In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That meant rethinking, reinventing, and optimizing dozens of scientific applications and software…

Learning With the Flow
The bigger the swirl, the bigger the problem — and the bigger the computing power needed to solve it. Computational fluid dynamics researchers have spent decades studying how liquids and gases flow in and around such machinery as airplane wings, propeller blades and jet engines in search of faster speeds…

A New Parallel Strategy for Tackling Turbulence on Summit
Turbulence, the state of disorderly fluid motion, is a scientific puzzle of great complexity. Turbulence permeates many applications in science and engineering, including combustion, pollutant transport, weather forecasting, astrophysics, and more. One of the challenges facing scientists who simulate turbulence lies in the wide range of scales they must capture…
