Astrophilately is a branch of philately which deals with the collection of stamps and postmarked envelopes related to spaceflight. It is the intersection of space and postal history. Covers cancelled on the date and at a post office near the controlling agency are used in postal exhibits to share the development and conquest of the cosmos.

Philately is the study of postage stamps and postal history. It also refers to the collection and appreciation of stamps and other philatelic products. While closely associated with stamp collecting and the study of postage, it is possible to be a philatelist without owning any stamps. For instance, the stamps being studied may be very rare or reside only in museums.
