From dreams to reality: unveiling the ideal in situ construction method for lunar habitats and paving the way to Moon colonization
Based on the technical mechanisms of bonding and cohesion between particles, regolith solidification and formation technologies can be categorized into four groups: reaction solidification (RS), sintering/melting (SM), bonding solidification (BS), and confinement formation (CF) methods.

As the lunar exploration mission evolves from exploration to construction and utilization, in situ lunar construction becomes an imperative requirement. The key is regolith solidification and formation, aiming to maximize local resource utilization while minimizing transportation and maintenance costs.

Nearly 20 techniques have been employed for preparing -based construction materials, each with distinct requirements and capabilities. Professor Feng from Tsinghua University has conducted a comprehensive review, precise classification, and quantitative evaluation of regolith solidification and formation techniques, shedding light on key challenges and future development directions.

In an effort to further humanity's journey to Mars, NASA has carefully selected a diverse group of four volunteers to undergo an intensive 45-day simulated mission to the Red Planet. This simulation will take place at the Johnson Space Center's Human Exploration Research Analog (HERA), a facility meticulously designed to mimic the conditions of space travel and planetary exploration. Parti

Did you know the Sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mission, blossoms around the center of a sunspot group, where magnetic conditions are strong. It straddles two atmospheric layers known as the chromos

Recent studies suggest that Mimas, one of Saturn's moons, has developed a substantial underground ocean due to a decrease in its orbital eccentricity, leading to the melting and thinning of its icy exterior. "Previously, we established that Mimas could currently host an ocean world only if it previously had a thicker icy shell. However, the process transitioning from thick to thinner ice w

The Lyrid meteor shower peaks this weekend, but it may be hard to see it
The Lyrid meteor shower is seen over Burg on the Baltic Sea island of Fehmarn off Germany, Friday, April 20, 2018. The Lyrids occur every year in mid-to-late April. Peak activity for 2024 happens Sunday, April 21 into Monday, April 22, with 10 to 20 meteors expected per hour, weather permitting. Viewing lasts through April 29.
