Symptoms
In the context of space and astronautical engineering, symptoms refer to any abnormal or unexpected behavior or performance of a spacecraft or its components. These symptoms can include anomalies in telemetry data, unexpected changes in spacecraft attitude or trajectory, or malfunctions in onboard systems or instruments. Identifying and diagnosing symptoms is a critical part of spacecraft operations, as it allows engineers to quickly respond to potential issues and prevent more serious problems from occurring. Symptoms can be caused by a variety of factors, including hardware failures, software errors, environmental conditions, or external factors such as radiation or micrometeoroids.
