IO Jupiter’s fifth moon, Io, is the most volcanically active body in the solar system. Io has more than 400 active volcanoes with average height of 6km on its surface. Plumes of sulfur spew upward as high as 300 kilometers. The surface of Io is splotched with lava lakes and floodplains of liquid rock. Io's atmosphere is made primarily of sulfur. Temperatures on Io vary from extremely hot to extremely cold. Areas which feature volcanic activity can reach temperatures of over 2000C, away from these areas however will see temperatures plunge to -143C. Io is subjected to tremendous tidal forces. which cause Io's surface to bulge up and down (or in and out) by as much as 100 m. As Jupiter rotates, it takes its magnetic field around with it, sweeping past Io and stripping off about 1 ton of Io's material every second. This material becomes ionized in the magnetic field and forms a doughnut-shaped cloud of intense radiation referred to as a plasma torus. Radiation on Io is 1000x stronger than is needed to kill a human being.

The actual NASA logo, known as meatball between NASA employees, was replaced with a logo called the ¨worm¨ that after sometime was replaced again with the ¨meatball¨ logo because most people likes more that logo, and in between there was a lost design that was mean to join both logos, the unofficial “wormball” was proposed as a “make everyone happy” design for the NASA insignia.
The National Aeronautics and Space Administration (NASA /ˈnæsə/) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research.[note 1] President Dwight D. Eisenhower established NASA in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958. (wikipedia)
