I recently watched the 2017 Russian film “The Spacewalker”. It tells the story of humanity’s first spacewalk. On March 18, 1965, Soviet cosmonaut Alexey Arkhipovich Leonov has stepped out of the Voskhod 2 spacecraft into the void of the space and became the first spacewalker ever.Continue reading The Spacewalker – Like Apollo 13 but Better
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.

Here’s the story: during the 1960s as NASA was sending the first astronauts to space, they realized that pens don’t work in zero gravity (or actually microgravity), so they spent years and many millions of taxpayer dollars to develop a “space pen”, which means a pen that can write in the microgravity. Meanwhile, the Soviet cosmonauts simply used pencils.
As Curious Droid pointed out in the video below, “the moral of the story to many is that NASA was a wasteful government organization that would be giving your hard-earned tax dollars to some greedy contractors charging sky-high prices for seemingly trivial objects whereas the enemy (the Soviet Union) was common sense and practical.”
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.

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.

A crescent-Earth photo, by an automatic camera aboard the unpiloted Apollo 4 command module on November 9, 1967, at an altitude of 11,200 miles (18,000 km). Apollo 4, (also known as AS-501), was the first unmanned test flight of NASA’s mighty Saturn V rocket, which was used by the U.S. Apollo program to send the first astronauts to the Moon.

Using data provided by Lunar Reconnaissance Orbiter spacecraftNotes 1 since 2009, NASA has published an amazing virtual Moon tour in 4K Ultra HDNotes 2. As the visualization moves around the near side, far sideNotes 3, north and south poles, interesting features, sites, and information gathered on the lunar terrain get highlighted.

46 years ago today, on April 16, 1972, the huge, 363-feet (110.6 meters) tall Apollo 16 (Spacecraft 113/Lunar Module 11/Saturn VNotes 1 SA-511) space vehicle was launched from Pad A, Launch Complex 39, Kennedy Space Center, Florida, at 12:54 p.m. EST. Crewed by Commander John W. Young, Lunar Module Pilot Charles DukeNotes 2, and Command Module Pilot Ken MattinglyNotes 3, it was the tenth manned mission in the United States Apollo space program, the fifth and penultimate to land on the Moon and the first to land in the lunar highlands.
