NASA's Dirty Problem.

Image
Sometimes the smallest things can be one of the biggest headaches. During the Apollo missions of 1969-72 the tiny particles of lunar dust turned out to be a major issue. Astronaut James B. Irwin, lunar module pilot, uses a scoop in making a trench in the lunar soil during Apollo 15 extravehicular activity (EVA). Mount Hadley rises approximately 14,765 feet (about 4,500 meters) above the plain in the background. Described as being as finest talc but as rough as sandpaper it also has properties that may be dangerous for both men and machines and has been cited as a bigger problem for future astronauts than radiation by some scientists. The lunar surface is covered in a thin layer of dust which has been created by the bombardment of meteorites and micro meteorites over millions of years.

How will the U.S. and NASA protect the Apollo landing sites from accidental damage and treasure hunters.

Image
With the 50th anniversary of the first moon landings coming up and the prospect of having new lunar explorers both state-sponsored and private companies how do you protect what are arguably some of the most important scientific and cultural historic sites in human history. You would think that the very position of the Apollo landing sites, the Russian lunokhods and the Chinese Jade rabbit would be enough to keep them safe but there is a similar parallel with a wreck of a Titanic. That sank in 1912 in 3800 meters, roughly 12,500 feet of water, its exact position unknown in what was thought to be an unattainable place, that was until its discovery in 1985 and within just a few years treasure hunters were recovering artifacts in what many compared to as grave robbing or the plundering of the pyramids. Check out my article about Why did we stop going back to the moon? here . Now obviously it's far more difficult to get to the moon than it is to the Titanic but thes...

Trash left on the moon.

With the surprise landing of a Chinese Rover Yutu 2 or the Jade rabbit 2 and the Chang'e lander on the far side of a moon on the 3rd of January 2019, I thought it'd be interesting to see what sort of things we've actually put up on the moon and to speculate on what might happen to them in the future. Neil Armstrong’s first photo taken after setting foot on the moon captures a bag of human waste that was jettisoned from the spacecraft NASA Now it will come as no surprise that the Apollo missions have left behind the most amount of items but long before they were even thought of the Soviets pulled off something that not for the first time the U.S. thought they couldn't actually do. In 1959 the Soviet Luna 2 probe was the first man-made object to intentionally impact on to the lunar surface, the closest to the US had got to the moon by then was with a pioneer for but that was 60,000 kilometers away which was a bit of a shock because the U.S. believed t...

Why did we stop going back to the Moon?

Image
The Apollo 11 Moon landing in July 1969 was a huge feat of human endeavour, engineering and science. It was a moment that the world had been waiting for. Buzz Aldrin descends onto the moon’s surface. Credit: Neil Armstrong/NASA. 2019 is the 50th anniversary of the Apollo 11 moon landings. Since then just 12 men have walked on the lunar surface in six missions covering a period lasting less than three years. The Apollo project at its peak employed over 400,000 people in some 20,000 businesses and universities with a total cost adjusted to 2019 figures of around about a $145 Billion. So after all the work money invested, why did our interest in it drop like a stone in a vacuum and what were the real reasons why we stopped going to the moon. Today Apollo is seen as a groundbreaking episode in our scientific understanding and technological abilities, in just over 60 years we've gone from the first powered flight of the Wright brothers to Neil Armstrong stepping onto ...

Navigating in Space, how do they do it?

Image
How does a space probe like Voyager 2 which was launched in 1977 visit the four outer planets and travel over 17 billion kilometers over a space of 40 years with almost next there nothing in the way of fuel. Apollo astronauts used three navigation systems to determine the proper flight paths to the Moon and back to Earth. These systems were used jointly or separately. Together they formed the Primary Guidance and Navigation System. By the time Voyager 2 had reached Neptune it had swung by Jupiter, Saturn and Uranus traveled 7 billion kilometers and was still within 100 kilometers of its target and all with mid-1970s technology. In the movies spacecraft just seemed to fly where they want and get there in no time at all but in our version of reality it's somewhat more complicated and takes much, much longer to get around. Can you imagine Spock saying to Kirk "we've just passed Pluto almost home only nine years to go" just in case you missed the rele...

A History of Moon Hoaxes

Go to google and type in site : moon hoax and you'll get back over 670,000 websites that reference in some way or another that the moon landings were faked or we have never been to the moon at all. Bond’s to blame ... Sean Connery in Diamonds Are Forever. Photograph: Allstar/UNITED ARTISTS. How did we get from one of the greatest technological achievements of the 20th century to believing that it was a massive cover-up by NASA the CIA the government or a combination of all three and why almost 50 years after the first Apollo missions with all the scientific proof available do an increasing number of people believe in a radically different version of reality. One of the first reported instances of people not believing but the moon landings were true came on December 18th 1969 when the New York Times science reporter John Noble Wilford in an article called "A moon landing? what moon landing?" remarked that a few stool warmers in the Chicago bars are on ...
