@Divy89682209 The black spots on the Moon are actually volcanic rocks. Billions of years ago, there were active volcanoes on the Moon. When they erupted, they filled in large basins left over from impact events. — PolitiTweet.org

@bigmark5485 Apollo astronauts and two remote landers of the Lunokhod program left retroreflectors on the Moon. These retroreflectors have allowed us to precisely measure the growing distance between the Earth and the Moon for over 50 years! — PolitiTweet.org

@gerardfitznl The Moon has a much lower gravity (about 17% the strength of Earth's gravity) and does not have an atmosphere like the Earth, this makes launching off the Moon much easier than launching off the Earth. — PolitiTweet.org

@amalbiju_astro @NASAMoon There have been lots of studies on Apollo samples since they were brought back, studying things like what the rocks are made of (their chemistry) and how old they are (most of them are over 3 billion years old). — PolitiTweet.org

@chiarodny For experimental purposes, cotton seeds were taken to the far side of the Moon by the Chang’e-4 lander in a mini biosphere. Unfortunately, it didn’t last, but we learned a lot about what works and what doesn't! — PolitiTweet.org

@cyb3rs341 Moonquakes are probably caused by the Moon's interior slowly shrinking as the Moon cools, making the surface shift slightly and wrinkle: https://t.co/966tfdxatl — PolitiTweet.org

@nz_list Rocks from space hit the Moon at all angles, but they hit at such tremendously high speeds that they cause explosions when they hit the surface. These explosions result in nearly round impact craters for all but the lowest-angle impacts. — PolitiTweet.org

@nehabokilwar Our Moon does not have any moons of its own, but sometimes asteroids and comets hit the Moon and eject material into space. Some of this material reaches the Earth as meteorites. ☄️ — PolitiTweet.org

@ElisaMcBride Great picture! 📸 The rings look like they are a result of overexposure from the camera. — PolitiTweet.org

@MoonToMarsQuest @planetarysci @dr_hendrix @Ryan_N_Watkins Mapping of lava tubes is a constant endeavor using the LRO camera. There are caves and tubes near the Moon's poles that could potentially lead to subsurface water sources. For solar radiation protection, we are also working on shield materials to make habitat living safer. — PolitiTweet.org

@eissana That would be interesting indeed! The answer would depend on things like the size/orbit of the additional moon(s). We do know that our own Moon is good for life as we know it. The Moon's gravity keeps Earth from wobbling on its axis too much, which helps to stabilize our climate. — PolitiTweet.org

NASA @NASA

@desh_neta There are a lot of similarities between Earth and Moon rocks, but the Earth has a greater variety of rocks because of higher temperatures, pressures, and the presence of liquid water, active volcanism, and an active mantle and core. — PolitiTweet.org

NASA @NASA

@subconsciousshy The best theory of how the Moon formed is called the Giant Impact Hypothesis, where a Mars-sized object hit the Earth and sent material into orbit around the Earth, which eventually came together to form the Moon. — PolitiTweet.org

@ml_sense And, the Moon is very special to the Earth: it affects our tides and keeps our Earth from wobbling on its axis too much, which helps stabilize the climate. — PolitiTweet.org

NASA @NASA

@ml_sense If on the Earth you can jump ~0.5 m, with the same jump on the Moon you could jump up to ~3 m. This is because the Moon's gravity is ~17% of the Earth's. Try it out: https://t.co/sFWp5MFZjC — PolitiTweet.org

@amir347347 The Moon takes about 27-28 days to orbit Earth (the exact orbital period depends on your frame of reference). The Moon's orbit is not circular, so it doesn't always move at exactly the same speed. It moves faster when it's nearer the Earth, and slower when farther away. — PolitiTweet.org

@IronCaniac Although the exact timing is not yet known, development for a base on the Moon is currently planned for after Artemis III. A station called the Gateway, which will orbit the Moon, will play a huge role in this. — PolitiTweet.org

@skyerummer @planetarysci @NASAMoon @dr_hendrix @Ryan_N_Watkins We need to understand more about the environment. We need to learn how to build using lunar materials, and we need to learn to extract materials we need from the rock. We also need to figure out how to keep lunar dust out of habitats. — PolitiTweet.org

@BoogLawlry A meteoroid is a rock moving through free space, a meteor is the light it produces as it flies through Earth's atmosphere, and the rock becomes a meteorite when it lands on Earth. A rock stuck to an EVA suit and brought back to Earth would be called a "sample collected in space." — PolitiTweet.org

NASA @NASA

@AydinFeatherst1 This would allow us to explore a great diversity of rocks and processes on the Moon without having to fly them home, do chemistry and physics in a vacuum better than any on Earth, and learn how to be a civilization that is capable of living and working in space all the time. — PolitiTweet.org

@what_wrong_with Meteoroids, but not meteors — there is no air on the Moon to make that glowing streak on the way to the ground. They hit all the time, but ones that make craters big enough for us to see from space (a crater maybe a few meters across) hit maybe a few times per year. — PolitiTweet.org

@ethan135789 Since the Moon is moving away from the Earth about 3.78 cm per year, models show that in about 650 million years into the future, solar eclipses will not occur. However, the Sun is also slowly growing in diameter, which slightly changes these models! — PolitiTweet.org

@slobostaios It is true! The Moon is moving away from the Earth at about 3.78 cm per year. — PolitiTweet.org

@cbrmj68 Not on the surface, but *under* the surface might be different. We don't know yet, but we have identified places to explore, like ocean worlds! For more: https://t.co/rpLhWzhLdq — PolitiTweet.org
