McCs

MCCs is an acronym that can refer to several distinct concepts across different fields. The most common meanings include Mission Control Centers, Monolithic Ceramic Capacitors, Mobile Country Codes, and the Mennonite Central Committee.

Mission Control Centers (MCCs) are facilities from which spaceflight missions are monitored and controlled. A typical MCC houses flight directors and spaceflight controllers who coordinate real-time operations, telemetry, tracking, and commanding. It provides a central interface for communications with spacecraft, planning teams, and support staff, often using secure data links and simulation environments. Historical MCCs supported programs such as NASA's Apollo and Space Shuttle, while contemporary MCCs support ISS operations and missions like Artemis, operating within a global network of linked centers.

Monolithic Ceramic Capacitors (MCCs) are a class of ceramic capacitors manufactured as a single solid block of dielectric material. They provide decoupling, filtering, and energy storage in electronics. Compared with multi-layer ceramic capacitors (MLCCs), MCCs generally offer different capacitance ranges and voltage ratings and are less common in modern consumer devices, having been largely superseded by MLCCs in many applications. They remain in use in some high-voltage, high-reliability, or legacy equipment.

Mobile Country Codes (MCCs) are three-digit identifiers defined by ITU-T E.212 to designate a country or region for mobile networks. In a mobile network's IMSI and in public land mobile networks (PLMNs), the MCC works with the Mobile Network Code (MNC) to route calls and data and to manage roaming. MCC assignments are country-based and are widely used by mobile operators and network equipment.

Mennonite Central Committee (MCC) is a relief, development, and peace organization formed by Mennonite and Anabaptist groups. It operates humanitarian aid, development projects, and advocacy in North America and around the world, often emphasizing nonviolence, community-based programs, and partnerships with local organizations. Context typically determines which MCC meaning is intended.
