The Deep Space Network (DSN) is a collection of three sites around the globe. The positioning of the sites, 120° longitude apart, allows at least one site to see every patch of sky at all times, thus facilitating continuous coverage for any deep...

The representation of mission operations systems (MOS) has been unique to each mission, although there are many common concerns that need to be addressed. A consistent approach and language are needed for representing mission operations systems. The Mission Service Architecture Framework (MSAF) is a...

Each mission needs to develop a Mission Operations System (MOS). Without a standard design to use as a reference, system engineers typically look to a subset of previous missions and develop a system with a mix of heritage, new design, and in some cases, reinvention of existing capabilities. If a reference...

The modeling of turbulent reactive flows is a subject of contemporary research. Current turbulent-reaction models cannot account for realistic complexities such as distinct species...

The NASA Earth Observing System Data and Information System (EOSDIS) is a data-centric system designed for the processing and archiving from NASA’s Earth Observation missions and their distribution, as well as provision of specialized services to users. The major...

The Space Communications and Navigation (SCaN) program is responsible for providing communications and navigation services to spaceflight missions located throughout the solar system. Astronauts, mission controllers, and scientists depend upon the reliable transmission of information between...

Many natural or complex engineered systems rely upon critical functions or processes that can be measured with the aid of various sensors or other novel devices. As a result, sensor and measurement data can be used to learn a parametric or non-parametric model of the behavior for a...

The Matlab Webification Science Client consists of several functions that access remote w10n-sci repositories to retrieve data. It supports user sessions to authenticate and authorize access to restricted repositories. In command line mode, it can list the contents of a w10n-sci node, change to other nodes, and...

This week's Question: A recent study from Common Sense Media found that parents spend more than nine hours (9:22) a day with screen media, with the vast majority of that time being spent with personal screen media (7:43) and only a little more than 90 minutes devoted to work screen media. Most parents...

A machine learning system from the Massachusetts Institute of Technology (MIT) recognizes sounds by watching video. The neural network interprets natural sounds in terms of image categories, without hand-annotated training data.
