Printing bricks from moondust using the Sun's heat

Bricks have been 3D printed out of simulated moondust using concentrated sunlight - proving in principle that future lunar colonists could one day use the same approach to build settlements on the Moon.
"We took simulated lunar material and cooked it in a solar furnace," explains materials engineer Advenit Makaya, overseeing the project for ESA.

Tiny lightning bolt explosions can vaporise the moon's thin soil

Mini-lightning may flash in the coldest craters on the moon, melting and vapourising soil. All that sparking could have altered the surface as much as impacts from incoming rocks and dust.
We already knew that impacts stir up the fine layer of dust and ground rock that covers the lunar surface. But now Andrew Jordan at the University of New Hampshire in Durham and his colleagues suggest we keep an eye out for another cause: electrical sparks.

'Shrapnel' risk to future Moon surface missions

The "shrapnel" generated by small space rocks that periodically hit the Moon may pose a larger risk to lunar missions than was previously believed.
A number of countries and private consortia have stated their plans to send robotic and crewed missions to the lunar surface in the coming decades.

Melvin Calvin's Moon Dust Reappears After 44 Years

When Apollo 11 returned from its historic flight in 1969, the moon rocks and lunar soil collected by Neil Armstrong and Buzz Aldrin eventually found their way to some 150 laboratories worldwide. One of those was the Space Sciences Laboratory in Latimer Hall on the UC Berkeley campus. After experiments were conducted and papers published, those samples should have been sent back to NASA. Instead they wound up in storage, where they sat collecting dust until they were discovered more than four decades later.

Leaping Lunar Dust

Electrically charged lunar dust near shadowed craters can get lofted above the surface and jump over the shadowed region, bouncing back and forth between sunlit areas on opposite sides, according to new calculations by NASA scientists.
The research is being led by Michael Collier at NASA's Goddard Space Flight Centre, Greenbelt, Md., as part of the Dynamic Response of the Environment At the Moon (DREAM) team in partnership with the NASA Lunar Science Institute (NLSI), managed at NASA's Ames Research Centre, Moffett Field, Calif.

Apollo's Lunar Dust Data Being Restored

Forty years after the last Apollo spacecraft launched, the science from those missions continues to shape our view of the moon. In one of the latest developments, readings from the Apollo 14 and 15 dust detectors have been restored by scientists with the National Space Science Data Centre (NSSDC) at NASA's Goddard Space Flight Centre in Greenbelt, Md.

  Structured Bubbles Found Inside Lunar Regolith Impact Glasses

Dr Marek Zbik, from Queensland University of Technology's Science and Engineering Faculty, studied the unusual morphology and internal structure of bubbles within lunar regolith impact glasses using traditional scanning electron microscopy and the novel technique of transmission X-ray microscopy (TXM), with 3D tomography reconstruction.
Vesicles within the lunar glasses are filled in with submicron-sized particles that consist of glass nano-size elements. Nano tomography is a transmission X-ray microscope which enables 3D images (video above) of nano particles to be made.

Stolen Apollo 11 moon dust recovered

The US has recovered a scattering of moon dust stolen from Nasa after the 1969 Apollo 11 mission, just as it was about to be sold at auction.
The dust was smuggled out of Nasa by a staff photographer who gathered it from a camera the astronauts used on the lunar surface, officials said.

Moon's interior water casts doubt on formation theory
 
An analysis of sediments brought back by the Apollo 17 mission has shown that the Moon's interior holds far more water than previously thought.
The analysis, reported in Science, has looked at pockets of volcanic material locked within tiny glass beads.
It found 100 times more water in the beads than has been measured before, and suggests that the Moon once held a Caribbean Sea-sized volume of water.

NASA-Funded Scientists Make Lunar Watershed Discovery
 
A team of NASA-funded researchers has measured for the first time water from the moon in the form of tiny globules of molten rock, which have turned to glass-like material trapped within crystals. Data from these newly-discovered lunar melt inclusions indicate the water content of lunar magma is 100 times higher than previous studies suggested.
The inclusions were found in lunar sample 74220, the famous high-titanium "orange glass soil" of volcanic origin collected during the Apollo 17 mission in 1972. The scientific team used a state-of-the-art ion microprobe instrument to measure the water content of the inclusions, which were formed during explosive eruptions on the moon approximately 3.7 billion years ago.
