Lunar Core Similar to Earth's

Post by Christopher K. »

Renee Weber (of MSFC) and colleagues have determined the Moon's center is much more like Earth's than previously realized. Using seismological data gathered during the Apollo era, the team have found it highly likely the Moon possesses an iron-rich core about 240 kilometers in diameter and a liquid-iron outer core about 330 kilometers in diameter. The Moon's total diameter is 3475 kilometers.

Four seismometers were activated between 1969 and 1972 by Apollo astronauts. The seismometers recorded continuously until 1977.

A March 1999 announcement revealed analysis from Lunar Prospector data suggested the Moon had a small core.

The two GRAIL spacecraft, slated to launch 8 September, will measure the lunar gravity field and accumulate data concerning subsurface features.

Even before NASA-TV, satellite, cable and such our American Space Program was promoting its attempt to get to the Moon. The short "300 Feet to the Moon" focused on training version of the Lunar Lander. NASA-TV will show "300 Feet to the Moon" on Friday 3 April at 11pm CDT.
