Launched in 1990, NASA's Hubble Space Telescope has made
more than 985,000 observations of roughly 32,000
In its 21-year lifetime the telescope has made more than
115,000 trips around our planet.
Hubble has racked up plenty of frequent-flier miles,
nearly 3 billion, which is roughly Neptune's average
distance from the Sun.
Over its more than two decades in space, Hubble has
produced more than 50 terabytes of data, which is
equivalent to about 50 million books, or five times the
printed collection of the U.S. Library of Congress.
Astronomers using Hubble data have published more than
9,400 scientific papers, making it one of the most
productive scientific instruments ever built.
