"...To the plaaaaanet core!" Boss Nass

] A Hollywood-like proposal to explore the center of the
] Earth calls for exploding a crack in the planet's surface
] and dropping a probe in behind tons of molten iron, which
] would sink and forge a path to the core.
]
] The plan is not ready for primetime, its creator told
] SPACE.com, but neither is it pie-in-the-sky.
]
] Exploring Earth's belly is ambitious in a scientific
] sense and could yield valuable data. The solid inner core
] rotates faster than the outer core, which is fluid and is
] responsible for Earth's magnetic field. But scientists
] don't know exactly why all this is so, nor do they know
] the exact composition or temperature of the core.
]
] A schematic shows how the probe would descend with molten
] iron, all in a crack that closes up behind the mission.
]
] If further research showed the core mission could
] actually work, it would be comparable in dollar terms
] with many space projects, says David Stevenson, a Caltech
] planetary scientist who has worked on several missions
] for NASA. Stevenson explains his idea in an article
] titled "A Modest Proposal" for the May
