The timing of the laser round trip provided evidence supporting Albert Einstein's theory of general relativity. That theory says, in part, that the speed of light in a vacuum is independent of any observer's motion. This experiment also showed that Isaac Newton's gravitational constant is extremely constant, changing by less than 1 part in 100 billion between 1969 and 2004, NASA stated.
This Crescent Moon Mirror shelf will brighten up any room with its reflective mirror surface and beautiful design! The bottom of the moon has copper chain and five crystal points hanging from them which are clear quartz and amethyst.That’s why despite several attempts over the last decade NASA Goddard scientists had been unable to reach LRO’s reflector until their collaboration with French researchers. Lost Soviet Reflecting Device Rediscovered on the Moon". Space.com. 27 April 2010 . Retrieved 26 January 2021. If those odds seem daunting, reaching LRO’s reflector is even more challenging. For one, it is a 10th the size of the smaller Apollo 11 and 14 panels, with only 12 corner cube mirrors. It’s also attached to a fast-moving target the size of a compact car that’s 70 times farther away from us than Miami is from Seattle. Weather at the laser station impacts the light signal, too, as does the alignment of the Sun, Moon and Earth. Laser experiments could help reveal if there’s solid material in the Moon’s core that would’ve helped power the now-extinct magnetic field. But to learn more, scientists first need to know the distance between Earth stations and the Moon reflectors to a higher degree of accuracy than the current few millimeters. “The precision of this one measurement has the potential to refine our understanding of gravity and the evolution of the solar system,” said Xiaoli Sun, a Goddard planetary scientist who helped design LRO’s reflector.
Magnetic measurements of Moon samples returned by Apollo astronauts revealed something no one had expected given how small the Moon is: our satellite had a magnetic field billions of years ago. Scientists have been trying to figure out what inside the Moon could have generated it. Besides the Earth-Moon drift, such measurements over a long period of time and across several reflectors have revealed that the Moon has a fluid core. Scientists can tell by monitoring the slightest wobbles as the Moon rotates. But they want to know whether there’s a solid core inside of that fluid, said Vishnu Viswanathan, a NASA Goddard scientist who studies the internal structure of the Moon. While the experiment is most famous for its measurements of lunar distance, researchers have also used the data to show that the moon has a fluid core and that the natural satellite is moving slowly away from Earth, said James Williams, a scientist at NASA's Jet Propulsion Laboratory involved in the experiment, in a 2009 Space.com interview.The reflector NASA scientists aimed for is mounted on the Lunar Reconnaissance Orbiter (LRO), a spacecraft that has been studying the Moon from its orbit since 2009. One reason engineers placed the reflector on LRO was so it could serve as a pristine target to help test the reflecting power of panels left on the Moon’s surface about 50 years ago. These older reflectors are returning a weak signal, which is making it harder to use them for science. The mirror's existence, and the fact that astronomers can bounce lasers off it and detect the returning beam, has also provided Nasa and other scientists with compelling evidence to refute the claims of moon-landing deniers who claim the Apollo lunar mission were hoaxes filmed in an Earth-based studio. The moon is made from strong safety mirror which makes it ideal to post. It has been stained in a dark oak colour and is ready to hang on the wall.
