Space science – study of everything in outer space.[1] This has sometimes been called astronomy, but recently astronomy has come to be regarded as a division of broader space science, which has grown to include other related fields,[2] such as studying issues related to space travel and space exploration (including space medicine), space archaeology[3] and science performed in outer space (see space research).
