Walt also became one of the first producers of films to venture into television, with his series Walt Disney's Wonderful World of Color (1954) which he began in 1954 to promote his theme park. He also produced The Mickey Mouse Club (1955) and Zorro (1957).
Because Mercury's magnetic field is weak while the interplanetary magnetic field it interacts with in its orbit (a perihelion at 0.307 AU and an aphelion at 0.467 AU) is relatively strong, the solar wind dynamic pressure at Mercuryâ²s orbit on the average is also a factor of three larger than that at Earth, for example.ike Earth's, Mercury's magnetic field is tilted, meaning that the magnetic poles are not located in the same area as the geographic poles. As a result of the north-south asymmetry in Mercury's internal magnetic field, the geometry of magnetic field lines is different in Mercury's north and south polar regions.
The origin of Mercury's magnetic field is still the subject of several competing theories. On March 24, 1975, just eight days after its final close approach, Mariner 10 ran out of fuel. Because its orbit could no longer be accurately controlled, mission controllers instructed the probe to shut down.
