Moon has liquid core just like Earth reveal sensors left on lunar surface by astronauts 40 YEARS ago. By Graham Smith Updated: 13:16 GMT, 7 January 2011 It's an unlikely marriage between state-of-the-art and 40-year-old technology that has yielded extraordinary results. Signals from seismic sensors left on the lunar surface by Apollo astronauts in 1971 have revealed that the Moon has a liquid core similar to Earth's.
Scientists at Nasa applied contemporary seismological techniques to the data being emitted from sensors placed by their colleagues during the U.S. space program's heyday. Core knowledge: Nasa applied contemporary seismological techniques to data being emitted from sensors left on the Moon in 1971. Scientists now think the Moon has a solid, iron-rich inner core and a fluid, primarily liquid-iron outer core The new research suggests the Moon possesses a solid, iron-rich inner core with a radius of nearly 150 miles and a fluid, primarily liquid-iron outer core with a radius of roughly 205 miles. Future Nasa missions will help gather more detailed data.

We look to Mars or the Moon as the perhaps the best places to find many of the natural resources we are using up on the physical planet. Given the current state of Earth-to-orbit boost technology, it is neither economical nor environmentally friendly to use rockets to loft the enormous volume of materials from the Earth's surface to build structures of the size of solar power satellites and space colonies in Earth orbit.
Fortunately, NASA's Apollo missions of the last century found that Lunar surface soils are comprised of about 20 percent metals (suitable for space construction) and 20 percent silicon (which is needed for making solar power cells). Much of the rest of lunar soil is composed of oxygen. Blue Moon - Crystalinks (Build 20100722155716) We are in the energies of a Full Moon/Blue Moon. Many people like to meditate at this time.

Earth's Moon in the News Moon's Age Revealed, and a Lunar Mystery May Be Solved Live Science - April 3, 2014 Scientists have pinned down the birth date of the moon to within 100 million years of the birth of the solar system - the best timeline yet for the evolution of our planet's natural satellite. This new discovery about the origin of the moon may help solve a mystery about why the moon and the Earth appear virtually identical in makeup, investigators added.
Scientists have suggested the moon was formed 4.5 billion years ago by a gigantic collision between a Mars-size object named Theiaand Earth, a crash that would have largely melted the Earth. 'Geologic clock' helps determine moon's age Science Daily - April 3, 2014 Planetary scientists have determined that the moon formed nearly 100 million years after the start of the solar system, according to a new article.

Earth's Moon - Crystalinks (Build 20100722155716) Earth's Moon The Moon is the only natural satellite of Earth. Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies. Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon's phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon's orbital period (measured against the stars) since the Earth moves a significant distance in its orbit around the Sun in that time.
The Moon is in synchronous rotation, meaning that it keeps nearly the same face turned toward Earth at all times (There is a small change however called libration). Orbit The Moon makes a complete orbit about the Earth approximately once every 29.5 days. Tidal effects Double-planet hypothesis Origin and History Physical Characteristics. Moon find may point to habitable tunnels.
Moon surface may hide tunnel network Could provide shelter for humans Join us over on Facebook | Twitter This hole spotted in the Moon's surface is 70m wide and 90m deep. Picture: NASA, JAXA US President Barack Obama may have to reconsider his decision to abandon plans to return to the Moon - it seems our closest galactic neighbour is still throwing up surprises. Last year, NASA'a Lunar Reconnaissance Orbiter (LRO) dipped into a low orbit around the Moon and almost immediately returned results. Early in May, it found lost Soviet rover Lunokhod 1, which wandered off course 40 years and stopped sending signals back to Earth. Later that month, it sent back an amazing image of a three-storey high boulder which had rolled across the Moon's surface before toppling into a crater. Now it may have confirmed a theory that scientists had held about the Moon since the 1960s - its surface may hide a vast network of tunnels. It was about 70m wide and dropped more than 90m to its floor.
