Capsules

A capsule is a small, enclosed container often used to encase medicine, supplements, or even spacecraft equipment. In the pharmaceutical world, gelatin capsules are commonly used to deliver drugs in a form that's easy to swallow, digest, and absorb. These capsules may be hard-shelled or soft-shelled, depending on the substance they contain—ranging from powdered medications to liquid extracts. In the realm of space exploration, a capsule refers to a pressurized module designed to carry astronauts or scientific instruments safely through atmospheric re-entry. In both cases, the capsule serves as a protective shell, preserving the integrity of its contents until the precise moment of release. Other related terms include encapsulation, dosage form, container, payload, and delivery system. Whether used in healthcare, technology, or aerospace, capsules are engineered to ensure safety, precision, and controlled delivery.
