Because Hubble orbits in the upper atmosphere, its orbit changes over time in a way that is not accurately predictable. The density of the upper atmosphere varies according to many factors, and this means that Hubble's predicted position for six weeks' time could be in error by up to 4,000 km. Observation schedules are typically finalized only a few days in advance, as a longer lead time would mean there was a chance that the target would be unobservable by the time it was due to be observed.
Engineering support for the Hubble is provided by NASA and contractor personnel at the Goddard Space Flight Center in Greenbelt, Maryland, 48 km south of the STScI. Hubble's operation is monitored 24 hours per day by four teams of flight controllers who make up Hubble's Flight Operations Team.

Jazz has, from its early 20th century inception, spawned a variety of subgenres, from New Orleans Dixieland dating from the early 1910s, big band-style swing from the 1930s and 1940s, bebop from the mid-1940s, a variety of Latin jazz fusions such as Afro-Cuban and Brazilian jazz from the 1950s and 1960s, jazz-rock fusion from the 1970s and late 1980s developments such as acid jazz, which blended jazz influences into funk and hip-hop. As the music has spread around the world it has drawn on local national and regional musical cultures, its aesthetics being adapted to its varied environments and giving rise to many distinctive styles.
Copy editing (also copy-editing and copyediting) is the work that an editor does to improve the formatting, style, and accuracy (but not content) of a manuscript. Copy (as a noun) refers to written or typewritten text for typesetting, printing, or publication.
In the United States and Canada, an editor who does this is a copy editor, and an organization's highest-ranking copy editor, or the supervising editor of a group of copy editors, may be known as the copy chief. In book publishing in the United Kingdom and other parts of the world that follow UK nomenclature, the term copy editor is used, but in newspaper and magazine publishing, the term is sub-editor, commonly shortened to sub ("to sub" is the verb form). The senior sub-editor on a title is referred to as the chief sub-editor.
There is no universal form for the job or job title; it is often written as one word (copyedit) or with a hyphen (copy-edit); the hyphenated form is especially common in the UK. Similarly, the term copy editor may be spelled either as one word, two words, or as a hyphenated compound term.
