- The lifecycle of most spacecraft consists of a final phase where all the systems are tested to various levels of synergy. One of the most important and complex set of tests are the Closed Loop Tests (CLTs), where the spacecraft is sent simulated orbital data, and then its attitude response is observed.
- Eukaryote (Wikipedia)
The eukaryotes (/juːˈkærioʊts, -əts/) constitute the domain of Eukarya, organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms are eukaryotes. They constitute a major group of life forms alongside the two groups of prokaryotes: the Bacteria and the Archaea. Eukaryotes represent a small minority of the number of organisms, but due to their generally much larger size, their collective global biomass is much larger than that of prokaryotes.
