OSO

OSO is an acronym used in various fields to designate unrelated organizations, programs, and concepts. The most historically prominent usage is Orbiting Solar Observatory, a NASA program that launched a series of satellites from the early 1960s into the 1970s to observe the Sun in ultraviolet and X-ray wavelengths. The OSO missions produced extensive solar data sets that advanced solar physics, including studies of solar flares and coronal activity.

In other contexts, OSO may stand for different entities depending on the organization or discipline. Because OSO is not tied to a single canonical entity, the intended meaning is usually clarified by accompanying context such as the field, organization, or dates.

When encountering OSO in a text, readers should check the definition provided by the author or source. This helps distinguish it from similarly named acronyms and ensures accurate interpretation. Because the same acronym can refer to multiple concepts, more precise identification relies on the surrounding information and documentation.
