National Aeronautics and Space Administration (NASA) has truly taken the Beatles song "Across the Universe" to heart. The federal agency was founded in 1958 -- partly in response to Russia's launch of the Sputnik satellite -- to research space and flight technology and, in 1969, successfully landed two Americans on the moon. Today it manages the space shuttle program; partners with several nations, including Russia, to build and man the International Space Station; and does research and exploration via unmanned satellites and probes (including the Mars Rovers and the Hubble Space Telescope). NASA plans to retire the space shuttle program by 2010 and deliver man back to the moon by 2020. [Description from Hoover's]

This list shows other sites an audience frequents, which can reveal brand preferences and other lifestyle traits. The Audience Also Likes section of a site's profile shows other sites that the audience is likely to visit, and the affinity indicates how much more likely than average. For example, if the profile for wsj.com listed barrons.com with an affinity of 10x, a randomly chosen visitor to wsj.com is ten times likelier to visit barrons.com than the average internet user.
Index represents how a site's audience compares to the online internet population as a whole. An index of 100 indicates a site's audience is at parity with the total internet population.
The affinity numbers represent how likely a given visitor is to visit one of the listed sites or categories compared to the internet average. For example, an affinity number of 10.2 would say that a user on "X" website is 10.2 times more likely than the average internet visitor to visit the other site or category that is provided.
