A Grand Challenge is a fundamental problem in science and engineering, with broad scientific and economic impact, whose solution can be advanced by high-performance computing.
Eight Grand Challenge Investigator teams chosen through a 1992 NASA Research Announcement completed their work in spring 1996. Efforts included probing the formation of the large-scale universe; modeling the global climate system in the past, present and future; ascertaining the dynamics of the interior of stars; and indexing and searching through massive Earth-observational data sets. The Grand Challenge Investigator teams and 21 Guest Computational Investigator (GCI) teams together comprised Science Team I.
