China Reveals How it’s Planning to Search for Water Ice at the Moon’s South Pole

It’s been a big week for Chinese space exploration. First a successful test flight of Zhuque-3 and this week we learned of their plans to explore the Moon’s South Pole. Previous missions have even returned samples to Earth but the Chinese landers have yet to explore more southerly areas of the Moon. Chang’e-6 is due to launch in a few months to collect samples from the far side of the Moon while Chang’e-7 launches in 2026 to the Moon’s south pole.

Japan’s Moon Lander Touches Down, But Power Problem Mars Its Mission

Update for Jan. 21: The Japan Aerospace Exploration Agency shut down its moon lander to conserve battery power, but says the lander might be recharged and revived if sunlight hits the solar cells at the right angle.

Japan has become the fifth nation to land a functioning robot on the moon, but the mission could fall short of complete success due to a problem with the lander’s power-generating solar cells.

Astrobotic Confirms it Won’t be Landing on the Moon

It’s a real shame that spaceflight is seen as routine by the world’s media. In reality, our exploration of the Solar System is still in its infancy, problems are still seen and sadly missions do still fail. We are reminded of this with the recent launch of the Astrobotic Peregrine lander on Sunday. It was launched atop a Vulcan rocket but it soon became apparent that there was a problem with the lander propulsion system. A leak has been discovered and unfortunately there is insufficient fuel to support a soft landing on the Moon.

The First Launch of ULA’s Vulcan Goes Smoothly, but there’s a Problem with its Lander Payload

Space missions regularly test multiple new technologies in one go. It’s very common to have a single mission test out three or more new technologies, making them “flight-proven.” Unfortunately, that sometimes means that though one particular new technology, or even many of them, might succeed, one technology could work. At the same time, another one could fail, and that single failure might mean that several other technologies might never even get a chance for their day in the Sun. That seems to have happened with NASA’s first Commercial Lunar Payload Services (CLPS) mission. While the Vulcan rocket, developed by the United Launch Alliance (ULA), lifted off successfully, the Peregrine lander, developed by Astrobotic, seems to have run into an error that jeopardizes the rest of the mission.

We Owe Our Lives to the Moon

Life appeared on Earth through a series of lucky coincidences, and that luck started with our Moon. None of the other planets of the inner solar system have significant moons. Space is lonely around Mercury and Venus. Mars does have two small moons, Phobos and Deimos (Fear and Despair, befitting companions for the God of War), but those are simply captured asteroids, lassoed in the not-too-distant past and doomed to eventually come close enough to their unloving parent to be torn to shreds by gravitational forces.

Questions Remain on Chinese Rocket That Created an Unusual Double Crater on the Moon

In November, we reported how an impact on the Moon from a Chinese Long March rocket booster created an unusual double crater. For a single booster to create a double crater, some researchers thought there must have been an additional – perhaps secret – payload on the forward end of the booster, opposite from the rocket engines. But that may not necessarily be the case.

Other researchers feel the extra mass wasn’t anything secretive, but possibly an inert structure such as a payload adapter added to the rocket to support the primary mission payload.

ESA is Stockpiling Simulated Regolith for the Ultimate Lunar Playground.

Testing interplanetary landers means putting them in an environment as close to their destination as possible. Mars landers are often tested in the ‘Mars Yard’ at NASA’s Jet Propulsion Laboratory in South California and now, ESA are looking to build a similar test bed for the Moon. They are mining a mateiral in Greenland known as Anorthosite to create the largest lunar test bed yet.

A Radio Telescope on the Moon Could Help Us Understand the First 50 Million Years of the Universe

In the coming decade, multiple space agencies and commercial space providers are determined to return astronauts to the Moon and build the necessary infrastructure for long-duration stays there. This includes the Lunar Gateway and the Artemis Base Camp, a collaborative effort led by NASA with support from the ESA, CSA, and JAXA, and the Russo-Chinese International Lunar Research Station (ILRS). In addition, several agencies are exploring the possibility of building a radio observatory on the far side of the Moon, where it could operate entirely free of radio interference.

For years, researchers have advocated for such an observatory because of the research that such an observatory would enable. This includes the ability to study the Universe during the early “Cosmic Dark Ages,” even before the first stars and galaxies formed (about 50 million years after the Big Bang). While there have been many predictions about what kind of science a lunar-based radio observatory could perform, a new research study from Tel Aviv University has predicted (for the first time) what groundbreaking results this observatory could actually obtain.

We've Entered a New Era: The Lunar Anthropocene

For almost half a century, the term “Anthropocene” has been informally used to describe the current geological epoch. The term acknowledges how human agency has become the most significant factor when it comes to changes in Earth’s geology, landscape, ecosystems, and climate. According to a new study by a team of geologists and anthropologists, this same term should be extended to the Moon in recognition of humanity’s exploration (starting in the mid-20th century) and the growing impact our activities will have on the Moon’s geology and the landscape in the near future.

For its Final Trick, Chandrayaan-3 Brings its Propulsion Module to Earth Orbit

On August 23, ISRO’s Vikram lander detached from its propulsion module and made a soft landing near the Moon’s south pole region. The lander then deployed its Pragyan rover, and for two weeks the endearing little solar-powered rover performed marvelously, detecting water ice and characterizing the makeup of the lunar regolith before succumbing to the darkness and cold of the lunar night.

But since the rover mission ended, the propulsion module that brought it to the Moon has made a detour, performing a series of complex maneuvers that took it from a tight lunar orbit back to Earth orbit. This was possible because the module still had more than 100 kg of fuel, allowing scientists to conduct additional maneuvers and experiments.
