China’s Lunar Lander Finds Water Under its Feet

Earlier this year, scientists from China’s Chang’E-5 lunar lander revealed they had found evidence of water in the form of hydroxyl from in-situ measurements taken while lander was on the Moon. Now, they have confirmed the finding with laboratory analysis of the lunar samples from Chang’E-5 that were returned to Earth. The amount of water detected varied across the randomly chosen samples taken from around the base of the lander, from 0 to 180 parts per million (ppm), mean value of 28.5?ppm, which is on the weak end of lunar hydration.

“For the first time in the world, the results of laboratory analysis of lunar return samples and spectral data from in-situ lunar surface surveys were used jointly to examine the presence, form and amount of ‘water’ in lunar samples,” said co-author Li Chunlai from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), in a press release. “The results accurately answer the question of the distribution characteristics and source of water in the Chang’E-5 landing zone and provide a ground truth for the interpretation and estimation of water signals in remote sensing survey data.”

A Geologic map of the Entire Moon has Been Released at 1:2,500,000-Scale

Chinese scientists have created the most detailed map of the Moon yet. It took them 10 years and involved hundreds of researchers. The new map will be a boon to lunar exploration and for anyone who just wants to study our natural satellite in more detail.

The Moon’s Ancient Volcanoes Could Have Created Ice Sheets Dozens of Meters Thick

Everyone loves looking at the Moon, especially through a telescope. To see those dark and light patches scattered across its surface brings about a sense of awe and wonder to anyone who looks up at the night sky. While our Moon might be geologically dead today, it was much more active billions of years ago when it first formed as hot lava blanketed hundreds of thousands of square kilometers of the Moon’s surface in hot lava. These lava flows are responsible for the dark patches we see when we look at the Moon, which are called mare, translated as “seas”, and are remnants of a far more active past.

In a recent study published in The Planetary Science Journal, research from University of Colorado Boulder (CU Boulder) suggests that volcanoes active billions of years ago may have left another lasting impact on the lunar surface: sheets of ice that dot the Moon’s poles and, in some places, could measure dozens or even hundreds of meters (or feet) thick.

Plants can grow in lunar regolith, but they’re not happy about it

NASA is sending astronauts back to the Moon by the end of this decade, and hope to send humans to Mars sometime in the 2030s. Growing food in space using in-situ resources is vital if astronauts are to survive on both the Moon and Mars for the long-term. Growing plants in space using Earth soil is nothing new, as this research is currently ongoing onboard the International Space Station (ISS). But recent research carried out on Earth has taken crucial steps in being able to grow food in space using extraterrestrial material that we took from the Moon over 50 years ago.

The Lunar Eclipse, Seen From the International Space Station

If you were able to witness the lunar eclipse on May 15-16, 2022, the view of the dark red Moon was stunning. But what would such an eclipse look like from space?

Wonder no longer. ESA/Italian astronaut Samantha Cristoforetti captured a series of photos of the lunar eclipse from her unique vantage point aboard the International Space Station (ISS).

Artemis 1 Probably won't Launch Until August

On March 17^th, the Artemis I mission rolled out of the Vehicle Assembly Building (VLB) and was transferred to Launch Complex 39B at the NASA Kennedy Space Center in Florida. This was the first time that a fully-stacked Space Launch System (SLS) and Orion spacecraft were brought to the launchpad in preparation for a “wet dress rehearsal.” To mark the occasion, NASA released a video of the event that featured a new song by Pearl Jam’s Eddie Vedder (“Invincible”).

Unfortunately, technical issues forced ground controllers to scrub the dress rehearsal repeatedly and return the Artemis I to the VLB on April 26^th. This was followed by reports that these issues were addressed and that Artemis I rocket would return to LC 39B by early- to mid-June. Meanwhile, an official NASA statement (issued on Thursday, May 8^th) says that the official launch of the mission is not likely to take place until August at the earliest.

One Giant Impact Made the Two Halves of the Moon so Different

The South Pole-Aitken Basin on the Moon formed from a gigantic impact about 4.3 billion years ago. But that impact may have changed everything about the Moon, and explain why the lunar farside looks so different from the nearside, the side we see from Earth.

Five Rover Teams Chosen to Help Explore the Moon’s South Pole

The Moon may seem barren, and it is. However, a certain species of inquisitive primates is still very interested in exploring the Moon, uncovering its secrets and maybe establishing a longer-term presence there. But thirsty primates need water, and there’s only one primary source on the Moon: the frozen water in shadowed craters at the lunar poles.

The Strange Swirls on the Lunar Surface are Somehow Related to Topography

The Moon is the most studied object in space. But our nearest neighbour still holds a few mysteries. One of those mysteries is the lunar swirls. These strange serpentine features are brighter than their surroundings and are much younger. They’re not associated with any specific composition of lunar rock, and they appear to overlay other surface features like craters and ejecta.

Scientists have been puzzling over the swirls for decades, and with lunar outposts looming as a real possibility, understanding these swirls takes on new importance. Now a new study finds a link between lunar topography and the swirls.

Future Mars Explorers Could be Farming Oxygen From Landscapes Like This

Viking’s biochemistry experiments have been among the most hotly debated scientific results of all time. The lander famously collected samples from the Red Planet in 1976, in an experiment called “Label Release.” Scientists watched with bated breath as oxygen was released from the sample after it was subjected to a liquid slurry. They were then left scratching their heads as that oxygen production continued after the sample was sterilized via 160 degree C heat. Scientists now really agree that the oxygen production that Viking noticed was an abiotic process. But that also leads to a potential opportunity as some scientists think we can make oxygen farms out of a system similar to that used on Viking itself.
