In computing, a shell is a computer program that exposes an operating system's services to a human user or other programs. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation. It is named a shell because it is the outermost layer ...
Computer engineering for the design of the on-board computers and computer buses. This subsystem is mainly based on terrestrial technologies, but unlike most of them, it must: cope with the space environment, be highly autonomous, and provide higher fault tolerance. It may incorporate space qualified radiation-hardened components.
It is a systems operation language that enables an operator or user to communicate a command to a computer system. The system interprets each high level language directive from the user and performs the indicated action, such as executing a program, printing out a snapshot, or sending a payload command.
The laboratory specializes in the design, development, and deployment of advanced technology solutions to problems in national security, space exploration, health care and energy. The laboratory was founded in 1932 by Charles Stark Draper at the Massachusetts Institute of Technology (MIT) to develop aeronautical instrumentation, and came to be ...
The NASA Advanced Supercomputing (NAS) Division is located at NASA Ames Research Center, Moffett Field in the heart of Silicon Valley in Mountain View, California.It has been the major supercomputing and modeling and simulation resource for NASA missions in aerodynamics, space exploration, studies in weather patterns and ocean currents, and space shuttle and aircraft design and development for ...

Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. [3] It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering.
Modeling at higher abstractions allows fast exploration of various design choices for the lower level implementation. The ability to operate on the space of design candidates makes DSE useful for many engineering tasks, such as rapid prototyping, optimization, and system integration. [2]
