Discover how retroreflectors on the Moon not only measure lunar distance but also debunk conspiracy theories about the Moon ...

Is the Moon’s slow retreat from Earth a cosmic time bomb in our planet’s relationship or an entry to the precision of modern ...

Researchers at Yunnan Observatories under the Chinese Academy of Sciences (CAS) used an infrared lunar laser ranging system of a recently upgraded 1.2-meter (3.9 feet) telescope to ping a small ...

Lunar laser ranging (LLR) remains one of the most incisive techniques for probing both the intricacies of the Earth–Moon system and the fundamental aspects of gravitational physics.

NASA has awarded Firefly Aerospace $176.7 million to deliver two rovers and three scientific instruments to the lunar surface.

To figure it out once and for all, Briaud and his colleagues collected data from space missions and lunar laser-ranging experiments to compile a profile of various lunar characteristics.

At present, a single observing session of about an hour yields a distance measurement with uncertainty of about 2~mm, an order of magnitude advance over the best pre-APOLLO lunar laser ranging data.

The first proposal, “Precision Lunar Laser Ranging,” is being led by Goddard astrophysicist Dr. Stephen Merkowitz.

After touchdown, ASI will enable long-term laser ranging observations of LaRA2 by lunar orbiters. Lunar navigation According to ASI and ispace-Europe, the agreement marks the first full-scale contract ...

Despite centuries of humanity using telescopes to collect and observe light from the moon, this curious experiment uses telescopes to focus and transmit pulsed laser light to the moon, then records ...

We have an incredibly accurate idea of how fast the Moon is currently moving away from us, thanks to the Lunar Laser Ranging Experiment. The Apollo missions in the 1960s and '70s placed reflectors ...
