(2) NASA and the project to build the first train on the moon
On May 2, 2024, the National Aeronautics and space Management (NASA) of the United States announced that the project to build the first train on the moon, named “Float” (FLOAT: Flexible Levitation On A Track) has been selected for the second phase of development. before reaching the final phase to continue official work by NASA
“Float” It is indeed a project of Jet Propulsion Laboratory NASA’s Jet Propulsion Laboratory (JPL) is based in California. Ethan Schaler, a robotics engineer, is the head of JPL’s Robotics Division and the project leader. Float
NASA’s method for building trains on the moon is different from how trains are generally built on Earth. As building trains on Earth requires the construction of permanent steel tracks.and requires a lot of human labor Working in the open air for long periods of time On the moon it would not be possible to use a lot of human labor. Because there is no air, water, and atmosphere on the moon to protect it from radioactivity from the sun and space.
NASA is pushing the boundaries of space exploration with its ambitious FLOAT (Floating on Lunar Terrain) project, aiming to construct the first-ever train on the moon. This isn’t your grandfather’s train; FLOAT utilizes cutting-edge maglev technology, promising a revolutionary approach to lunar logistics.

Unlike traditional trains relying on physical tracks, the FLOAT system employs magnetic levitation – “magnetic levitation (lifting or floating with a magnet),” as the project describes it – similar to the high-speed Maglev trains already in use globally. This innovative approach eliminates the need for extensive track construction on the lunar surface.
Rather of laying down rails, the FLOAT project will utilize a “trail sheet,” a flexible, graphite-coated material deployed on the moon’s surface. This sheet generates the magnetic force necessary to levitate and propel the train cars. ”The tracks are coated with a highly flexible film called graphite to create magnetic force. Raise the train carriages to float on the road. and push or pull the locomotives to move forward or pull slowly to park,” explains the project documentation.
This groundbreaking approach considerably reduces the labor and resources required for lunar infrastructure development. the trail sheets can be manufactured on Earth and then deployed on the moon as needed, even rolled up for storage and reuse in different locations. This eliminates the need for extensive on-site construction.

Initially,the FLOAT train won’t be transporting passengers. Rather, these maglev vehicles will serve as crucial cargo carriers, transporting essential materials like soil, rocks, water, and fuel for the construction of lunar bases and scientific research facilities. This is a critical step towards establishing a permanent human presence on the moon.
The FLOAT project is currently in its second phase of development, following a prosperous first phase completed between 2021 and 2024. With approximately two years remaining in phase two, successful completion will pave the way for the final phase and potential deployment. The project’s success is closely tied to NASA’s Artemis program, aiming to return humans to the moon and establish a long-term lunar presence. The declaration of FLOAT’s progress is an vital part of the Artemis Project to return humans to the moon a second time and to be permanently on the moon.

The FLOAT project represents a significant leap forward in lunar exploration, promising efficient and sustainable transportation solutions for future lunar settlements. Its success could redefine how we approach large-scale construction and resource management on other celestial bodies.
Japan’s “Moon Sniper” Achieves Historic landing, Faces Power Challenges
Japan has joined an elite club, becoming the fifth nation to successfully land a spacecraft on the moon. The Japan Aerospace Exploration Agency (JAXA) announced the successful touchdown of its SLIM (smart Lander for Investigating Moon) probe on January 19,2024. However, this milestone achievement comes with a twist: the lander’s unusual orientation is limiting its operational lifespan.

SLIM, nicknamed the “Moon Sniper” for its precision landing capabilities, aimed to touch down within 100 meters of its designated target. While it met this ambitious goal, the lander’s position is less than ideal. Initial reports indicate SLIM landed at an angle, with its solar panels facing away from the sun, towards the west of the moon. This unfortunate positioning significantly restricts the spacecraft’s power supply, leaving it with limited battery life.
The mission’s primary objective was to demonstrate pinpoint landing technology, a crucial step towards future lunar exploration and resource utilization. This technology could revolutionize how we approach landing on other celestial bodies, potentially paving the way for more complex missions, including those involving human exploration.
Before its landing, SLIM successfully deployed two small rovers, LEV-1 and LEV-2, onto the lunar surface. These rovers are expected to contribute valuable data to the mission,despite the challenges faced by the main lander. The landing site is near the Shioli crater, a region known for its challenging terrain, which likely contributed to SLIM’s unusual landing posture.
Despite the unexpected complications, JAXA considers the mission a partial success. The agency’s ability to achieve a pinpoint landing, even with the subsequent power limitations, represents a significant technological leap forward. The data gathered from SLIM and its rovers will be invaluable in refining future lunar landing techniques and informing the design of more robust and adaptable spacecraft.
The success of SLIM places Japan alongside the United States, Russia, China, and India as a nation capable of achieving a soft landing on the moon. This achievement underscores the growing global interest in lunar exploration and the ongoing competition to develop advanced space technologies. The lessons learned from SLIM’s landing will undoubtedly shape future missions and contribute to humanity’s continued exploration of the cosmos.
Japan’s SLIM Lunar Lander Delivers Stunning Moon Images Before Powering Down
Japan’s ambitious Smart Lander for Investigating Moon (SLIM) mission, while ultimately concluding its active operations, delivered a remarkable achievement: transmitting breathtaking images of the lunar surface before entering a power-saving mode. The Japan Aerospace Exploration Agency (JAXA) confirmed the lander’s initial success, highlighting the groundbreaking precision landing technology tested during the mission.

Initially, after landing, SLIM entered a “sleep” mode, hoping to recharge its batteries with sunlight. While JAXA wasn’t certain of a successful reactivation, the lander did eventually power back up and transmit data. However,contact was subsequently lost,leading JAXA to officially terminate SLIM’s operations on August 23,2024.
Beyond the precision landing technology demonstration, SLIM’s mission included geological studies, specifically focusing on the mineral olivine. The presence and analysis of olivine could provide crucial evidence supporting the theory that the moon originated from Earth. This mission also served as a critical test for future missions, paving the way for potential sample collection from Phobos, one of Mars’ moons.
“The Slim ship finally wakes up and receives sunlight,” a JAXA spokesperson stated, referring to the lander’s temporary reactivation. “and thus successfully carried out the big mission as intended.Until Jacksa was unable to contact the Slim ship again.”

Fish Employ Punishment to Maintain Order
In a separate study, researchers at Osaka Metropolitan University published findings indicating that fish also utilize punishment as a method of social control and discipline within their groups. Further details on this research are available through the university’s publications.
Fish Punishment: Redefining Animal Intelligence
A groundbreaking study published in the May 2024 issue of Animal Behavior challenges our understanding of animal intelligence, revealing complex social dynamics in cichlid fish, specifically the Neolamprologus savoryi species. The research demonstrates that these fish utilize punishment to enforce group discipline—a behavior previously thought to be exclusive to higher vertebrates, including humans.

The study, conducted by a team of scientists, aimed to investigate whether the use of punishment to maintain group cohesion was a genuine behavior in N. savoryi. Researchers designed experiments to observe the fish’s social interactions within their groups.
Their findings revealed that the cichlids employed punishment methods—inflicting harm—on young fish and group members who neglected their duties in protecting the habitat and breeding grounds. This behavior served at least two crucial purposes: safeguarding the territory from intruders and ensuring the safety of the breeding area.
Significantly, the researchers observed that punished fish subsequently modified their behavior, actively participating in protective duties. This demonstrates the effectiveness of punishment as a disciplinary tool within the fish community.
Professor Satoshi Awata, a key member of the research team, commented on the study’s implications: ”Other than humans, animals also use punishment for creating behavior that sustains the group… and said, ‘We need to consider and study the meaning of “intelligence” again, not just in the fish but with the entire animal kingdom.'”
This research has profound implications for our understanding of animal cognition and social structures.It suggests that complex social behaviors, previously considered unique to humans and other highly intelligent species, may be far more widespread in the animal kingdom than previously thought. Further research is needed to explore the prevalence and nuances of this behavior across diverse species.
