The Moon, Earth’s sole natural satellite, has long fascinated humans with its mysterious and seemingly barren landscape. While we’ve made significant strides in exploring our nearest celestial neighbor, there’s still much to be discovered. One intriguing question that has garnered attention in recent years is: what temperature does water freeze on the Moon? To answer this question, we’ll embark on a journey through the Moon’s unique environment, exploring the factors that influence water’s freezing point and uncovering the surprises that await us.
The Moon’s Harsh Environment: A Look at the Lunar Surface
Before delving into the specifics of water’s freezing point, it’s essential to understand the Moon’s extreme environment. The lunar surface is characterized by:
- Extreme temperatures: Daytime temperatures can soar up to 253°F (122°C), while nighttime temperatures plummet to -387°F (-233°C).
- Low air pressure: The Moon’s atmosphere is extremely thin, with a pressure about 1/100,000th of Earth’s.
- Radioactive radiation: The Moon has no atmosphere to shield it from harmful radiation, making it a challenging environment for both humans and electronics.
- Lack of atmosphere: The absence of air means there’s no wind, weather, or sound on the Moon.
These extreme conditions make it difficult for water to exist in its liquid form on the lunar surface. However, scientists have discovered evidence of water ice in certain regions, particularly in permanently shadowed craters near the poles. This water ice is thought to have originated from comets and meteorites that collided with the Moon over billions of years.
The Freezing Point of Water: A Brief Primer
On Earth, water freezes at 32°F (0°C) under standard atmospheric pressure. However, this temperature can change depending on various factors, such as:
- Pressure: Increasing pressure lowers the freezing point of water.
- Impurities: The presence of impurities or dissolved substances can alter the freezing point.
- Surface tension: Water’s surface tension can also affect its freezing point.
Given the Moon’s unique environment, it’s reasonable to expect that the freezing point of water might differ significantly.
The Lunar Freezing Point: A Surprising Discovery
In 2018, a team of researchers from the University of Colorado Boulder conducted an experiment to determine the freezing point of water on the Moon. Using a combination of computer simulations and laboratory experiments, they found that water can remain liquid on the Moon’s surface at temperatures as low as -143°C (-225°F). This is significantly lower than the freezing point of water on Earth.
The researchers attributed this phenomenon to the Moon’s extremely low air pressure. With so little pressure, water molecules are able to move more freely, making it more difficult for them to form the crystalline structures necessary for ice formation.
This discovery has significant implications for future lunar exploration and potential human settlement. It suggests that water may be more abundant on the Moon than previously thought, and that it could potentially be used as a resource for life support, propulsion, and other purposes.
Practical Applications of Lunar Water

What is the average temperature on the surface of the Moon?
The average temperature on the surface of the Moon varies greatly depending on the time of day and the location on the Moon. When the Sun is overhead, the temperature can reach as high as 253°F (122°C) near the equator. However, when the Sun is not shining, the temperature can drop to as low as -387°F (-233°C).
The reason for this extreme temperature fluctuation is due to the Moon’s lack of atmosphere. Without an atmosphere to insulate or protect the surface, the Moon is exposed to direct sunlight and the coldness of space. This results in extreme temperature variations between day and night.
