Fact-Check: "On the moon, exposed liquid water wouldn't freeze"

What We Know

The claim that "on the moon, exposed liquid water wouldn't freeze" is contradicted by scientific understanding of the Moon's environment. The Moon has no significant atmosphere, leading to extreme temperature fluctuations. During the lunar night, temperatures can drop to approximately -173°C (-280°F) in shadowed areas (NASA SVS). This extreme cold would cause any exposed liquid water to freeze almost instantaneously.

Additionally, NASA's Lunar Reconnaissance Orbiter has discovered evidence of water ice in permanently shadowed craters at the Moon's poles, where sunlight never reaches, indicating that water can exist in solid form under these conditions (Moon Water and Ices). Furthermore, a study highlighted that water molecules have been detected on the sunlit surface, but these exist primarily as hydrated minerals rather than as free liquid water (NASA finds water on the Moon).

Analysis

The assertion that liquid water would not freeze on the Moon is fundamentally flawed. The Moon's lack of atmosphere means that any exposed liquid water would be subject to the vacuum of space, which causes rapid evaporation and freezing due to the extreme cold. According to a Forbes article, liquid water in a vacuum will freeze quickly when temperatures drop below freezing.

Moreover, the concept of water existing in liquid form on the Moon is highly speculative and not supported by current scientific evidence. Studies have shown that while water ice can exist in shadowed regions, the conditions required for liquid water to remain stable are not present on the Moon's surface (Water vs. the Moon: What Happens When Liquid Meets Lunar ...). The extreme temperatures and lack of atmospheric pressure would lead to immediate freezing or evaporation.

The sources used in this analysis are credible, with NASA being a leading authority in space exploration and lunar studies. The information is based on empirical data gathered from lunar missions and scientific research.

Conclusion

The claim that "on the moon, exposed liquid water wouldn't freeze" is False. The Moon's extreme temperatures, particularly in shadowed areas, would cause any exposed liquid water to freeze almost instantly. Current scientific understanding, supported by credible sources, indicates that while water ice can exist in certain regions, liquid water cannot remain stable on the Moon's surface due to the harsh environmental conditions.

Fact Check: Water in space quickly evaporates into water vapor, it quickly freezes. Now it depends on how close you are to the Sun or whether you are hidden from it when it comes to what happens next. Close to the Sun, in full sunlight water would eventually vaporize. That's why on Mercury and the Moon, ice only exists in permanently shadowed craters. But because the outer solar system is far from the Sun, ice can exist on the surface without any problems.
