Safe Mode
A pre-programmed, low-power, and stable operational state that a spacecraft enters automatically when it detects a serious problem. It's designed to protect the spacecraft until ground control can intervene.
TECHNICAL DEFINITION
Safe Mode is an autonomous, pre-programmed operational state a spacecraft enters upon detecting a critical anomaly or system failure, prioritizing survival by shutting down non-essential systems, orienting for power/thermal stability, and awaiting ground intervention.
BACKGROUND
The International Space Station (ISS) is a space station in low Earth orbit (LEO). It is the product of the International Space Station program and is operated by five partner space agencies: NASA, Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). It is the first space station built, maintained and crewed through international cooperation and the largest human spacecraft ever constructed. It is an orbital research station, where scientific experiments in microgravity are conducted and the space environment is studied. Since 2 November 2000, it has hosted the longest continuous presence of humans in space. Alongside Tiangong, it is one of the only two currently operational space stations.
