How much ice is on the Moon?
The Moon holds hundreds of billions of kilograms (or over 1.3 trillion pounds) of water ice, primarily located in permanently shadowed regions (PSRs) at the north and south poles. This ice is mixed with lunar soil (regolith) rather than forming thick, pure sheets, with recent studies suggesting it is less extensive than previously believed, though still significant for future exploration. The Planetary Society +4Is there a lot of ice on the Moon?
We know there's water ice in deep, shadowed craters near the moon's poles. The ice remains frozen due to the lack of sunlight and extreme cold. But there's even more ice on the moon than we previously knew, according to a new NASA study. The evidence comes from data obtained by NASA's Lunar Reconnaissance Orbiter.How much ice is in the Moon?
How much water is on the Moon? Based on remote observations by radar instruments aboard Chandrayaan-1 and LRO, the lunar poles have over 600 billion kilograms of water ice. That's enough to fill at least 240,000 Olympic-sized swimming pools.How did astronauts survive the temperature on the Moon?
Astronauts survived the Moon's extreme temperatures (scorching hot in sun, freezing in shadow) using multi-layered, reflective spacesuits with built-in liquid cooling systems (LCVG) and sublimators to actively remove body heat, while landing during lunar dawn to avoid the most intense heat, all within a vacuum that acts like a thermos, insulating them but requiring active heat management.Is the US flag still on the Moon?
Yes, most of the American flags left on the Moon by the Apollo missions are still standing, according to images from NASA's Lunar Reconnaissance Orbiter (LRO), though they are likely bleached white and may have fallen over due to the harsh environment (like rocket exhaust) or the flag's design, with the first Apollo 11 flag being the main exception.Evidence for surface water ice on the Moon
Why can't we go to the Moon anymore?
We haven't gone back to the Moon primarily due to shifting political priorities, immense costs, and the complex technological re-development needed, as focus shifted from the Cold War race to the ISS and Mars, leading to lost expertise and infrastructure, though NASA's Artemis Program aims to return humans with new technology.What did China find on the dark side of the Moon?
China's lunar missions to the far side of the Moon, particularly Chang'e-4 and Chang'e-6, found deep mantle material from the giant South Pole-Aitken basin, younger volcanic rocks than expected, unique hydrated minerals with helium-3, evidence of water in lunar soil, rare carbon nanotubes, and asteroid fragments (CI chondrites) in the regolith, challenging previous understanding of lunar evolution and composition.Do astronauts wear condoms in space?
Yes, astronauts historically used condom-like devices (specifically, condom catheters) for urine collection on early missions like Apollo, connected to a bag, but modern space stations use sophisticated toilets, while astronauts on spacewalks wear Maximum Absorbency Garments (MAGs) or diapers for waste management, as true condoms aren't used for sexual purposes in space, with hygiene and gravity presenting major challenges.How much does a 200 lb man weigh on the Moon?
[/caption] Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.How is the sun so hot if space is cold?
Space is cold because it's mostly a vacuum with very few particles to absorb and hold heat, while the Sun is hot because it generates immense energy that travels as radiation, heating up any matter it strikes, like Earth, but the empty space itself remains frigid. Heat transfer needs a medium (conduction/convection), which space lacks; objects in space get hot in sunlight and freeze in shadow due to rapid heat loss by radiation, showing extreme temperature swings, say IFLScience and Popular Science.What's the coldest the Moon can get?
Surface temperatures on the Moon range from higher than 250°F to lower than -410°F. The Moon has hardly any atmosphere and no global magnetic field to shield it from space radiation. Since the Moon is exposed to radiation from the Sun and beyond, human and robotic explorers require special precautions to stay safe.Where is 90% of water found on Earth?
The ocean holds about 97 percent of the Earth's water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.What did Harrison Schmitt find on the Moon?
Harrison Schmitt, the only geologist to walk on the Moon (Apollo 17), famously discovered orange soil, which turned out to be tiny volcanic glass beads from ancient fire-fountain eruptions, providing key evidence of explosive lunar volcanism. He also collected significant samples, including Troctolite 76535, a rock suggesting the Moon once had a magnetic field, and experienced firsthand the effects of lunar dust, finding it felt like damp sand and smelled like gunpowder, and even caused him temporary "lunar hay fever".Is the water on the moon drinkable?
Water appears to be abundant near the moon's south pole, but drinking it could be a safety problem for astronauts. A new moon challenge asks the public for ideas to purify drinking water for astronauts, reducing the need for shipments from Earth.What is the coldest place on the Moon?
In 2009, the Diviner instrument revealed that an area within Hermite Crater is the coldest place ever measured in the Solar System, with a temperature of -249 degrees Celsius. This cold temperature is due to the fact that regions within this crater, which is located near the Moon's north pole, never see sunlight.Is there anything worth mining on the Moon?
Yes, the Moon has valuable resources like water ice, rare earth elements, and especially Helium-3, making lunar mining potentially lucrative for future space economies, though primarily for use in space or for high-tech Earth applications like fusion power and quantum computing, rather than bulk shipping back. Water for fuel/life support, rare earths for electronics, and Helium-3 for clean fusion energy are key targets, driving interest from both governments and private companies.Can I touch a piece of the Moon?
Yes, you can touch a piece of the Moon at several museums and exhibits, like the National Air and Space Museum in D.C. or Space Center Houston, where you can touch actual lunar samples brought back by Apollo missions, but touching the Moon's surface directly with bare hands is not possible and would be dangerous due to vacuum and sharp dust.How heavy would I be on the sun?
Your mass (how much matter you're made of) stays the same, but gravity — the force pulling you toward a planet's surface — doesn't. Let's break it down: 🔹Sun – 3,627 lbs (1,645 kg): You wouldn't just feel heavy — you'd be crushed instantly under 28x Earth gravity. (Also, don't stand on the Sun.)How heavy would I be on Mars?
For example, a trip to Mars would cause a dramatic weight change. Someone who weighs 150 pounds (68 kilograms) on Earth would weigh in on the Red Planet at just 57 pounds (26 kg). The difference is because of Mars' weaker gravitational pull on the person.Can astronauts drink alcohol in space?
Alcohol is generally disallowed in spaceflight, but space agencies have previously allowed its consumption. NASA has been stricter about alcohol consumption than the Roscosmos, both according to regulations and in practice. Astronauts and cosmonauts are restricted from being intoxicated at launch.Do female astronauts wear bras in space?
Yes, female astronauts wear bras in space, often opting for comfortable sports bras for support during daily activities and especially exercise, as the lack of gravity means there's no downward pull but movement still causes breast displacement, making support beneficial for comfort, similar to on Earth. While normal bras can be worn, sports bras are favored for preventing discomfort during activities like running on the treadmill, though underwires are generally avoided for comfort and practicality.How do breasts behave in space?
They still follow the motion of the body and don't suddenly become rigid. They just don't drop down by default, only when you're moving upwards. Well, things only bounce in gravity. In space, they would just ride higher than they do on Earth, much like they do when women are in water.Is it true that China has made an artificial sun?
China's artificial sun just ran at 158 million degrees for 30 minutes China's EAST reactor — nicknamed the “artificial sun” — just set a world record that stuns even nuclear physicists. The experimental fusion reactor sustained temperatures of 158 million degrees Fahrenheit for over 30 minutes.What is being mined on the Moon?
In 2024, an American startup called Interlune announced plans to mine Helium-3 on the Moon for export back on Earth. The first mission plans to use NASA's Commercial Lunar Payload Services program to arrive on the Moon.Is Yutu-2 still working?
Yes, Yutu-2 (Jade Rabbit 2) is still operating and is the world's longest-working lunar rover, exceeding its original design life by years and still sending back data and images as of late 2024, though its movement slowed significantly by early 2024, and it may have become immobile after March 2024 but remained functional, with updates in September 2024 showing continued data transmission.
