looking for aliens on the moon - metal plaque engraving

When astronauts return to the moon, they should keep their eyes open for alien artifacts-technologies from alien civilizations that are either accidental or designed.
Ian Crawford, a researcher at the University of London's berbeck College, said.
At a meeting of experts at the Royal Astronomical Society, he saidRAS)
It was in London last week, though he thought the discovery was long term.
The shot is definitely worth remembering.
"This is not the main reason for returning to the moon-there are very strong scientific reasons for returning to the moon.
"But if we return to the moon in the next 20 or 30 years, then we may want to keep our eyes open and focus on alien art," Crawford told New Scientist . ".
The focus of the RAS discussion is to look for the history and current state of alien intelligence-an effort that has so far relied primarily on large radio telescopes to listen to electronic signals from other technological civilizations.
Crawford believes that scientists will hope that the next lunar astronaut will be able to screen the lunar soil in a larger and more detailed way, which is possible in the Apollo era.
Therefore, keeping open to the idea that aliens may be present on the surface of the moon has little extra cost.
Seth Shostak, a senior astronomers at the SETI Institute in Mountain View, California, said the possibility of such an interesting return makes the idea of finding art worth considering.
"On the moon, I think it's definitely worth it to take a few hundred square feet of material and look at it again," he said . ".
But researchers at SETI "may not be putting their mortgage on the hunt for anything ".
Shostak pointed out that looking for small artifacts, even detectors or time capsules, in our solar system is not a new idea in the SETI community.
In fact, our own civilization has taken this approach many times.

Carrying information, images and sounds that describe life on Earth for use by any aliens that may be encountered thousands of years later.
In 2004, an engineer and a physicist published a paper in the journal Nature, proposing that if aliens are not in a hurry, the best opportunity for them to engage with other civilizations will not be wireless but there is a Interstellar message in the bottle-a physical artifact that tells other intelligent lives, forming something about their existence.
Given the lack of geological activity and air-free environment on the moon, Crawford said, it would be a good target for this "engraved substance.
But if the intentional aim of a relatively small body sounds a bit like 2001 & colon;
He said that space rover could also be first caught his attention by a 1998 paper by Ukrainian astronomers Alexei ashibov.
This suggests that if enough space society exists, even if they have never surpassed their own planetary system, they may have produced enough space debris to make Micron
Particles of size can reach our own solar system.
Crawford said the tiny substance could fall on the moon and stay 10 to 15 metres on Earth.
But several moon experts will describe the prospect of discovering alien artifacts on the moon as "far away --fetched”.
Gary Lofgren, director of the moon for the scientific preservation of Apollo Moon samples at the Johnson Space Center in Houston, said that even such alien microns
The size of the particles are there and it is very difficult to find them, requiring special instruments that have never been sent into space before.
Apollo astronauts brought a total of 842 pounds (382 kilograms)
Lunar materials and researchers to the Earth are still studying samples today.
Lofgren said & Cologne
"People have gone through these samples in great detail and have not found anything that suggests alien activity.
"In fact, he says scientists are even surprised at the fact that rocks on the moon-matter produced by meteorite impacts on Earth or Mars, for example.
Still, scientists are keen to study new samples on the moon, Lofgren said, noting that Apollo's samples cover only six sites around the equator.
He said the discovery of substances in the solar system that cannot be explained by origin and evolution "would be an incredible discovery ".
Scott Hubbard, former director of NASA's Ames Research Center, is now a researcher at the SETI Institute
"While nothing is impossible, I found a return from looking for a comet --
Falling into the permanent shadow of the moon, the crater is more noticeable than the artifacts of the alien civilization.
