Information resiliency refers to the continuous availability of uncorrupted mission-critical information to support business or military operations, even under the threat of a cyber attack. An information resilient enterprise will continue to engage in its critical operations, despite the attacker’s attempts to intrude, corrupt or deny service. The manner and efficiency with which the operation...

Computing speed isn't just a convenience. Faster computers allow us to solve larger problems, and to find solutions more quickly, with greater accuracy, and at a lower cost. All this adds up to a competitive advantage. In the sciences, this may mean the difference between being the first to publish and not publishing. In industry, it may determine who's first to the patent office. Traditional h...

As XML becomes ubiquitous throughout the enterprise, it increasingly taxes the systems that must deal with it. [. . . ] Even though it is inefficient, however, XML’s numerous advantages are increasing its use for ever broader and more mission-critical functions. [. . . ] XML’s processing overhead, storage requirements, and bandwidth consumption become quite problematic when transaction volumes ...

NASA's mission crilical Hubble Space Telescope (HST) command and control system has been re-engineered x,_th commercial-off-theshelffgovernment-off-the-shelf (COTS/GOTS)and minimal custom code. This paper focuses on the design of this new HST Control Center System (CCS) and the lessc41s learned throughout its development. CCS currently utilizes more than 30 COTS/GOTS products with an additional...

The optimal design of the propulsion system for a potential Mars Ascent Vehicle is analyzed, in context Sample Return Mission. has to perform an initial ascent phase from surface and then circularize into 170 km orbit. A two-stage launcher taken account: same hybrid rocket engine considered both stages order limit development costs. cluster two, three or four engines employed first stage, where...

Since all Department of Defense (DoD) missions depend on cyber assets and capabilities, a dynamic and accurate cyber dependency analysis is a critical component of mission assurance. Mission analysis aims to identify hosts and applications that are “mission critical” so they can be monitored, and resources preferentially allocated to mitigate risks. For missions limited in duration and scale (t...
