The absence of an atmosphere (there is no wind or rain on the Moon) means the lunar landscape is perfectly preserved and could help us to learn more about the evolution of our solar system.
On the Moon, solar wind is more or less an everyday affair. An invisible electric breeze bathes the sunlit lunar surface, growing calmer for a few Earth days each month as our planet's magnetosphere provides a partial shield. Lunar scientists know the solar wind as a chemical factory, a landscape artist, and more.
On the moon, there's no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere.
We cannot see the flags on the Moon with Earthbound telescopes, but we know they are still standing tall thanks to the Lunar Reconnaissance Orbiter. The flag support bar latch failed on the Apollo 12 flag pole and remains forever collapsed on Oceanus Procellarum. Photo courtesy of NASA.
Is There Weather on the Moon? We Asked a NASA Scientist
Is the Apollo 11 flag still on the Moon?
Only one flag, the one planted during Apollo 11, appears to have fallen over—which matches a report from Aldrin that exhaust from the lunar module's engine knocked down the flag as he and Armstrong lifted off from the moon.
Oxygen is in fact the most abundant element, making up almost half (47 per cent) of the Earth's crust. On the Moon, the proportion is somewhat lower, but not by much. More than 40 per cent of the lunar crust is composed of oxygen.
Moon's gravity does not cause winds on the Earth. It is well known that the Moon causes the tides of the oceans on Earth. Tidal forces affect the atmosphere too, but to a much lesser extent when compared to the oceans. Atmosphere is less responsive to tidal forces because it is so much less dense than water.
Is there an atmosphere on the Moon? For a long time scientists thought that there was no atmosphere on the Moon, but recent studies have confirmed that there is one. The very thin atmosphere, known as an exosphere, contains helium, argon, neon, ammonia, methane and carbon dioxide.
In the vacuum of space, there is no water or air, and thus there also isn't any precipitation. But there is wind — solar wind — that isn't air at all, but instead is a stream of energy and plasma, or charged particles, from the Sun. Space weather storms are invisible but still impact Earth.
Why does the Moon not crash into the Earth if the Earth is pulling on it with gravity?
The moon's velocity and distance from Earth allow it to make a perfect balance between fall and escape. In case the velocity of rotation of the moon was a little bit faster, it would have escaped the Earth's Gravity. On the other hand, if it's a little bit slower, it would have fallen on Earth.
How did astronauts survive the temperature on the Moon?
They wore spacesuits made from layers of nylon and Kapton film, which can withstand temperatures of -269°C (-452°F) to 400°C (752°F). Teflon-coated glass fibre was used for the outside of the space suits to reflect the Sun's rays and maintain a comfortable temperature.
The Viking and Pathfinder observations showed that the mean wind speed on Mars is fairly weak: 1 – 4 m/s (about 4 – 15 km/h). However, under some extraordinary conditions – such as in the event of global or local dust storms – winds are expected to blow at speeds over 30 m/s or even more (> 110 km/h ).
Sound requires a medium to travel. However, there is no atmosphere on Moon, i.e., there is no medium for sound to travel. Hence, no sound can be heard on the Moon.
A full moon will not directly affect the weather, but when the tides and weather are working hand in hand, the situation can be exacerbated and cause problems on shore.
Well, because the Moon doesn't have a significant atmosphere like Earth, it does not experience weather, like wind or atmospheric temperature or precipitation like rain and snow. However, the Moon does experience what we refer to as space weather.
As the Moon has virtually no atmosphere, there is virtually no air resistance. The lack of atmosphere is also responsible for the extreme temperatures on the Moon, whereas the atmosphere of the Earth acts like a blanket trapping heat.
The short answer is, not very long. "Within a very short time, a matter of 10 to 15 seconds, you will become unconscious because of a lack of oxygen," according to Stefaan de Mey, a senior strategy officer at the European Space Agency (ESA) charged with coordinating the strategy area for human and robotic exploration.
The temperatures in the Moon's core are estimated to be around 1000 to 1500 degrees Celsius (1832 to 2732 degrees Fahrenheit), compared to the much hotter temperatures in Earth's core, which can exceed 5000 degrees Celsius (9032 degrees Fahrenheit).
Putting humans on the moon and returning them safely to Earth is expensive. Once the USA felt they won the space race by being first to the moon, the American government soon cut funding for the Apollo program and funding for a renewed manned lunar never came back.
Here's why: 🇺🇸 The Moon is about 238,855 miles away from Earth. 🇺🇸 The smallest objects we can observe on the Moon are about a mile across. 🇺🇸 The flag is only 4 feet wide! So, unfortunately, you can't see the flag with your telescope.
Unfortunately, there is no telescope on Earth powerful enough to spot any of the objects that have been left behind. Not even the Hubble could see what's left on the moon. It's designed to collect faint light of galaxies and nebulas, not objects on the moon.
