NASA has published an amazing video titled “Moonlight (Clair de Lune)”, which attempts to capture the mood of the French composer Claude Debussy’s (22 August 1862 – 25 March 1918) best-known composition, Clair de Lune (moonlight in French).Continue reading Lunar Landmarks meets Debussy’s “Moonlight” in this Amazing NASA Video
The Moon is completely uninhabitable and lifeless today – a dusty, dry rock. It has no atmosphere, there is no liquid water on the surface, and, maybe the most important, it has no magnetosphere to protect its surface from solar wind and cosmic radiation. But, according to a new study published in Astrobiology, it may have looked quite different around four billion years ago: its surface was not as dry as it is today, and conditions to support simple life on the Moon existed twice during the early years.Continue reading Life on the Moon? New study suggests there was a habitability window 4 billion years ago
NASA has just published Two Years’ Worth of Apollo 11 Mission Audio (the first manned moon landing mission) on their website “Explore Apollo“. That’s more than 19,000 hours of audio.

The mighty Saturn V, the rocket that took humans to the moon, remains the tallest, heaviest, and most powerful rocket ever brought to operational status (as of 2018). It was used by NASA between 1967 and 1973. It was powered by five Rocketdyne F-1 engines. With a thrust of 1,746,000 lbf (7,770 kN) in vacuum (1,522,000 lbf / 6,770 kN at sea level), the F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed.

To able to reach the space, we need rockets. Rocket engines work by action and reaction (“To every action, there is always opposed an equal reaction”Notes 1) and push rockets forward simply by expelling their exhaust in the opposite direction at high speed and can therefore work in the vacuum of space. Space rockets are usually enormous in size, because the bigger the rocket is, the more thrust can produce its engine and can carry more weight into the orbit. Here are the 10 tallest rockets ever launched in the history of space exploration.

To put things into a perspective, here are the moons of our solar system (including our moon) and their sizes compared to Earth.

On his Twitter account, Andrew Jones, a journalist reporting on China’s space programme and related activities, has published amazing images of the Earth and the Moon captured from China’s Queqiao lunar communications relay satellite, a key component of Chang’e 4 lunar landing mission.

If you go out on a clear night when it’s full moon, you may notice how gigantic the Earth’s satellite looks when it’s near the horizon. But, in fact, that moon is the exact same size as every other time as you’ve ever seen it in the sky. You can test this by holding your thumbnail at arm’s length and comparing it to the size of the Moon when it is near the horizon and high in the sky, and you’ll see it doesn’t change size. Photographs of the Moon at different elevations also show that its size remains the same. In fact, it plays a trick on your brain which called the “Moon Illusion”. This illusion has been known since the ancient times, and an explanation of this optical phenomenon is still debated.

Yesterday, I stumbled upon a YouTube channel named The Science Asylum. In this channel, physicist Nick Lucid covers some popular science subjects. For example, the video below, titled “How Far Away Is The Moon?” explains the distance between the Earth and the moon, and how our brains aren’t good at dealing with the big numbers.

Alan Bean, the fourth person to walk on the Moon has died today (May 26, 2018). He was the fourth person to walk on the Moon: in November 1969, he spent 10+ hours on the lunar surface during Apollo 12 mission, the sixth manned flight in the United States Apollo program and the second to land on the Moon.
