Moon Rock Believed as Old as Solar System

Moon rock or lunar rock is rock that is found on the Earth’s Moon including lunar material collected during the course of human exploration of the Moon , or rock that has been ejected naturally from the Moon’s surface and which has then landed on the Earth as meteorites. Moon rocks on Earth come from three sources: those collected by the United States Apollo program crewed lunar landings from to ; samples returned by three Soviet Luna programme uncrewed probes in the s; and rocks that were ejected naturally from the lunar surface before falling to Earth as lunar meteorites. A moon rock known as “NWA ” which weighs The Soviet Union attempted, but failed to make crewed lunar landings in the s, but they succeeded in landing three robotic Luna spacecraft with the capability to collect and return small samples to Earth. A combined total of less than half a kilogram of material was returned. Rocks from the Moon have been measured by radiometric dating techniques. They range in age from about 3. In contrast, the oldest ages of rocks from the Earth are between 3.

Moon Rocks Still Awe, And Scientists Hope To Get Their Hands On More

Darby Dyar says that as a kid, whenever Apollo astronauts returned from the moon, she and her classmates would get ushered into the school library to watch it on TV. She remembers seeing the space capsules bobbing in the ocean as the astronauts emerged. Nearly a half-ton of moon rocks were collected by the six Apollo missions to the lunar surface.

And as the 50th anniversary of the Apollo 11 first landing mission approaches, NASA has decided to open a still-sealed, never-studied moon rock sample that has been carefully saved for decades, waiting for technology to advance. Dyar is one of the scientists picked to do experiments on this pristine sample. She has spent her whole career studying the moon rocks she first saw on television as a child, although back then she never would have guessed it.

Nearly a half-ton of moon rocks were collected by the six Apollo missions By dating rocks from lunar craters, they can tell when different-sized.

Written by Marc Norman Lunar and Planetary Institute and Australian National University A northosites, rocks composed almost entirely of plagioclase feldspar, are the oldest rocks on the Moon. They appear to have formed when feldspar crystallized and floated to the top of a global magma ocean that surrounded the Moon soon after it formed. Not all ages determined for anorthosites, however, are as old as we expected–one appeared to be only 4.

While 4. One possibility is that the young ages reflect impact events, not the original time of igneous crystallization. But even that age might have been affected by the subsequent shock heating event that reset the low-temperature components in this rock about million years after it formed. By examining data for all of the previously dated lunar anorthosites, we were able to show that plagioclase feldspar is more prone to shock damage than are the pyroxenes in these rocks, so we plotted only the pyroxene data for four different anorthosites on a samarium-neodymium isochron diagram.

These data fall on a well-defined line indicating a crystallization age for the anorthosites of 4. Other data for show that it comes from a relatively shallow depth in the crust, giving us clues to the structure of the lunar crust. Studies like this one are filling in the picture of how the initial crust of the Moon formed, which in turn sheds light on the formation of the terrestrial planets. Reference: Norman, M.

Lunar Sample Science Today

Like Earth and the rest of the solar system , the moon has been around for roughly 4. But try to narrow down the planets age any more than that, and scientists have a hard time agreeing. Is our moon an ” old moon ” that formed 30 million years after the solar system took shape, or a ” young moon ” that formed million years later? In a new study published July 29 in the journal Nature Geoscience , scientists describe fresh evidence that our moon is apparently on the older side.

By analyzing the ratios of rare radioactive elements in a sampling of moon rocks collected during the Apollo missions, scientists from Germany narrowed the date of the moon’s formation down to about 50 million years after the birth of our solar system — million years earlier than many studies estimate.

Fifty years ago, Apollo astronauts collected their first moon rocks. By dating rocks from lunar craters, they can tell when different-sized.

Researchers are developing instruments and methods for measuring the ages of rocks encountered during space missions to the Moon or other planets. Many of the techniques used to date rocks on Earth are not practical in spaceflight, but a technique called laser ablation resonance ionization mass spectrometry can avoid the need for sophisticated sample preparation. A team led by Dr. Scott Anderson has now demonstrated that this technique can successfully date an Earth rock — the Duluth Gabbro — that is analogous to the rocks that cover one-third of the lunar nearside.

Their results, published in Rapid Communications in Mass Spectrometry, imply that events from Solar System history that are recorded on much of the visible face of the Moon can one day be dated directly by instruments aboard a lunar lander. Dating the Duluth Gabbro was approximately 30 times more analytically challenging than our previous experiment, dating the Martian meteorite Zagami, noted co-author Dr. Jonathan Levine.

Moon Rocks Reveal That We Were Very Wrong About The Age of The Moon

The following radioactive decay processes have proven particularly useful in radioactive dating for geologic processes:. Note that uranium and uranium give rise to two of the natural radioactive series , but rubidium and potassium do not give rise to series. They each stop with a single daughter product which is stable.

How Apollo moon rocks reveal the epic history of the cosmos By age-dating the moon’s craters, we can age-date craters elsewhere.

It will be the first time in decades that anyone has opened a pristine Apollo sample. Fresh studies of Apollo-era samples could help to shape the next generation of lunar geological discoveries, researchers said at the meeting.

Before man walked on the Moon, scientists thought that the Moon was a relatively primitive simple object that would record the earliest history of the Solar System. More than 50 U. A total of 24 U.

Indeed, samples collected by space missions consist essentially of surface samples taken from the regolith at the surface of the Moon. By contrast, lunar meteorites have sampled deeper material. In addition, samples returned by missions are taken from locations that are tightly clustered, in places where it was easy to land, which can induce a bias.

The high number of impacts made by meteorites means that these samples are far more random and can originate from anywhere on the Moon. For meteorites and for some returned samples, the sampled area s can be larger than just the place from which the sample originated. The numerous impacts have ejected material with sufficient energy to travel up to a few hundred kilometres away from the impact point.

These findings suggest that the Moon was formed roughly 60 million years after the Solar System first formed, making it up to million years older than previous estimates. The impact that formed the Moon could have been large enough to wipe out any living thing on Earth, so knowing when that collision occurred is important if we hope to understand the evolution of our own planet, and when early life took root here. And the new research suggests that it happened earlier in the timeline of the Solar System than we thought – just 60 million years after our star system’s birth, compared to previous estimates of to million years afterwards.

To come up with the new lunar age estimate, the team analysed Moon rocks taken from the lunar surface during the Apollo 14 mission.

Scientists computed the age of the Apollo 11 moon rocks times using Grenville Turner, “Argon/Argon Dating of Lunar Rock Samples” pages.
