Data from India’s recent Chandrayaan-3 mission supports the idea that an ocean of molten rock once covered the moon. Scientists from the mission have published their new findings in the journal Nature. On August 23 2023, a lander called Vikram successfully touched down on the lunar surface. Controllers then deployed a rover called Pragyan, which … Read more
Earth’s days once got more than two hours longer, thanks to the moon drifting thousands of miles farther away in its orbit over two periods, researchers have discovered. The extra hours of sunlight, in turn, may have led to oxygenation events that ushered in a period when life’s complexity exploded, the study researchers say. “Daylength … Read more
The Moon’s surface is pockmarked with more than 200 known pits where rocks and regolith collapsed into depths unknown. New research has found that one of those pits, in Mare Tranquillitatis, collapsed into a lava tube and made an underground cave conduit accessible from the lunar surface. “We found a sort of front door to … Read more
It is easy to imagine the moon as an atmosphere-less hunk of rock orbiting Earth. However, while lacking breathable air, our planet’s loyal natural satellite companion does have a thin and wispy atmosphere. Scientists have long puzzled over the existence of this tenuous atmosphere or “exosphere” and have searched for the main process that sustains … Read more
Scientists in China have discovered water molecules trapped in lunar rocks, upending past assumptions that the moon’s surface is dry. The rock samples, collected from the moon’s surface and brought back to Earth by China’s Chang’e 5 mission in 2020, contain crystals filled with “hydrated molecules,” according to the Chinese Academy of Sciences. Samples brought … Read more
It would appear that the so-called “great instability” event that wreaked chaos among the planets, sending the gas giants careening through space until they settled into the orbits we know today, occurred between 60 and 100 million years after the birth of the solar system. This is the conclusion of some careful scientific detective work … Read more
NASA test drove the mini autonomous rovers that will soon fly to the moon and collectively map the lunar surface. The rovers are part of a technology demonstration called Cooperative Autonomous Distributed Robotic Exploration (CADRE), which is designed to show that a group of robotic spacecraft can work together without direct human control. NASA took … Read more
The moon is much more seismically active than we realized, a new study shows. A reanalysis of abandoned data from NASA’s Apollo missions has uncovered more than 22,000 previously unknown moonquakes — nearly tripling the total number of known seismic events on the moon. Moonquakes are the lunar equivalent of earthquakes, caused by movement in … Read more
Within the next few decades, NASA aims to land humans on the Moon, set up a lunar colony and use the lessons learned to send people to Mars as part of its Artemis program. While researchers know that space travel can stress space crew members both physically and mentally and test their ability to work … Read more
When plotting sites for crewed lunar landings — ranging from the forthcoming Artemis missions to eventual lasting moon settlements — mission planners must account for tons of lunar parameters. For instance, the shape of the terrain could make or break a mission and a possible high volume of buried water could make one spot much … Read more
