Only 12 humans (the crews of Apollo 11, 12, 14, 15, 16 and 17) have ever walked on the moon's surface.
However, a new study suggests that the Moon may have played a pivotal role in maintaining Earth’s habitability in those very early days. Areas of the moon locked in permanent shadow, like those shown here, can still harbor water. Image Credit: William Zhang, NASA - National Aeronautics and Space Administration, Heather R.

The necessities for life are there, and maybe Enceladans are as well. The creations were entries in NASA's first Life and Work on the Moon art contest. And on the moon’s surface, temperature fluctuates between (average) -184 C (-300 F) in the shade and 111 C (232 F) in the sun. The Sun’s intense radiation may have threatened to degrade Earth’s atmosphere to a point that life could never catch on, but the Moon, as it turns out, may have helped a lot.
4.7 out of 5 stars 91. — How each of these factors contributes to the evolution of planetary habitability, and hence life, is still not fully understood.
Because the moon's gravity is only one-sixth that of the Earth's gravity, Apollo astronauts had to tread carefully or else risk stumbling or falling.
A new study, published in Science Advances, suggests that the Moon’s now extinct magnetic field may have helped protect our planet’s atmosphere as life was forming around 4 billion years ago. What about Mars, or Venus or Mercury? Thank you for signing up to Space. For most astronomers, Saturn’s moon Enceladus tops the list in terms of having just the right conditions to host life.

For example, the brightness and activity of the Sun has evolved over billions of years and so has the ability of the solar wind to strip atmospheres.
Such studies have, however, unveiled that Earth has generated a magnetic field for at least the last 3.5 billion years, and possibly as far back as 4.2 billion years, with a mean strength just over half of the present-day value. Scientists rely on ancient rocks that contain small grains that got magnetised as the rocks formed, saving the direction and strength of the magnetic field at that time and place.
What’s more, a strong magnetic field does not guarantee the continued habitability of a planet’s atmosphere – its surface and deep interior environments matter too, as do influences from space.
But to know for sure we need further modelling and more measurements of the strengths of the Earth and Moon’s early magnetic fields. One is the existence of a strong and long-lived magnetic field.
The new research investigates how the Earth’s and Moon’s early fields may have interacted. Keeping the fluid moving requires energy, such as heat trapped within the core. searching for water? Visions of hovering spacecraft, lunar greenhouses and dome-like habitats on the cratered surface of the moon came to life in the artwork of students who used their artistic talents to illustrate what it may someday be like to live and work on the moon. While it is possible that water ice with cometary origins possesses organic material or even spores (Panspermia Hypothesis), that water ice is in permanently shadowed craters on the poles of the Moon and thus frozen at ~ -200 C. Thus there is no presence of liquid water on the moon.
Such rocks are rare and extracting their magnetic signal requires careful and delicate laboratory measurement. University of Leeds provides funding as a founding partner of The Conversation UK.

The Sun’s intense radiation may have threatened to degrade Earth’s atmosphere to a point that life could never catch on, but the Moon, as it turns out, may have helped a lot. The solar wind can also collide with the atmosphere and knock molecules into space.
We know that a combination of water, heat, and maybe even impacts from extraterrestrial objects likely played a role in taking the building block of life and turning them into something more. Global magnetic fields are generated by the motion of molten iron in the cores of planets and moons.
