develops flight software for small spacecraft missions. The team developed flight software for the Lunar Atmosphere Dust and Environment Explorer (LADEE) mission, which orbited the Moon before crashing into it to study the contents of the plume of the crash. CAST develops software using a model-based development process, starting from requirements, then proceeding to design models (generally in Simulink), and then auto-coding (when possible) into core Flight Software (cFS\/cFE) applications. The development process follows the Agile methodology, with short coding sprints. In terms of software quality and assurance, CAST is a proponent of testing early and often, meaning that CAST uses RSE-developed capabilities to test artifacts as early as design models, and uses a suite of automated software engineering tools, such as software version management, continuous integration, bug tracking, and various documentation tools.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Mission<\/h3>\n\n\n\n<ul>\n<li><strong>BioSentinel<\/strong> is a low-cost CubeSat spacecraft on a space biology mission that will use budding yeast to detect, measure, and compare the impact of deep space radiation on DNA repair over long time beyond low-Earth orbit.<\/li>\n\n\n\n<li>The <strong>Starling<\/strong> series of demonstration missions will test technologies required to achieve affordable, distributed spacecraft “swarm” missions that are: scalable to at least 100 spacecraft for applications that include synchronized multipoint measurements; involve closely coordinated ensembles of two or more spacecraft operating as a single unit for interferometric, synthetic aperture, or similar sensor architectures; or use autonomous or semi-autonomous operation of multiple spacecraft functioning as a unit to achieve science or other mission objectives at low-cost. <strong>Starling1<\/strong> will focus on developing technologies that enable scalability and deep space application.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:41px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Group Lead<\/strong><\/p>\n\n\n\n<p>Joseph Castle<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Group Members<\/strong><\/p>\n\n\n\n<p>Nathan Benz<br>Scott Christ<\/p>\n\n\n\n<p>Howard Cannon<\/p>\n\n\n\n<p>Edmund De la Cruz<\/p>\n\n\n\n<p>Vinh Doan<br>Kandy Fabreo<\/p>\n\n\n\n<p>Leigh Garbs<\/p>\n\n\n\n<p>Mohammad Hejase<\/p>\n\n\n\n<p>Michael Ho<\/p>\n\n\n\n<p>Tony Koudsi<\/p>\n\n\n\n<p>Robert Lim<\/p>\n\n\n\n<p>Matthew Knudson<\/p>\n\n\n\n<p>Andrew Mikhail<\/p>\n\n\n\n<p>Craig Pires<\/p>\n\n\n\n<p>John Rasmussen<br>James Roach<\/p>\n\n\n\n<p>Todd Sarshad<br>Kevin Seywald<\/p>\n\n\n\n<p>Dave Varvell<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Associate Members<\/strong><\/p>\n\n\n\n<p>Antony Gillete<br>Eddy Mazmanian<\/p>\n\n\n\n<p>Dawn McIntosh<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Core Avionics & Software Technologies Group Overview The Core Avionics and Software Technologies (CAST) group develops flight software for small spacecraft missions.
