They call it a blue moon, but it has nothing to do with the colour. It’s really a reference to its rarity.
What is even rarer is for there to be a blue moon on Halloween, says Jack Burnett, managing editor for The Old Farmers Almanac.
The last one was 19 years ago on Oct. 31, 2001 according to Burnett.
The blue moon is the second full moon in the same month.
“It only comes up once, sometimes twice a year,” said Burnett.
“The moon has always been a mysterious orb in the sky, and it’s always been felt to have sort of mysterious powers,” Burnett said.
That obsession with the moon goes back to Celtic traditions and the early Christian All Hallows Day celebrated on Nov. 1. The night before, All Hallows Eve, is believed by many to originally be a Celtic harvest festival, which gave the moon great relevance in daily life.
“So because… the moon has always been so mysterious, it’s been associated with Halloween.
And of course, now we see that we have the full hunter’s Blue Moon on Saturday night, it makes it all the more spookier and you know, all the more Halloweenier,” Burnett said.
Traditionally, hunters would be out hunting for food this time of year using the light of the moon to help them.
Ever wonder where the saying once in a blue moon comes from? According to Burnett it comes from an old English word that meant betrayed.
“So that meant that they felt it had betrayed the normal cycles of the moon by showing up, you know, an extra time. So that’s one theory as to how the actual word came about.”
And is it blue? No, not unless there is ash or something else in the air to make it appear blue, Burnett said.
In addition to the rare full moon on Halloween, don’t forget that early Sunday morning, clocks will also fall back one hour.
Nasa sets prices for Moon dust – Bangkok Post
WASHINGTON: The US space agency Nasa awarded contracts to four companies on Thursday to collect lunar samples for US$1 to $15,000, rock-bottom prices that are intended to set a precedent for future exploitation of space resources by the private sector.
“I think it’s kind of amazing that we can buy lunar regolith from four companies for a total of $25,001,” said Phil McAlister, director of Nasa’s Commercial Spaceflight Division.
The contracts are with Lunar Outpost of Golden, Colorado for $1; ispace Japan of Tokyo for $5,000; ispace Europe of Luxembourg for $5,000; and Masten Space Systems of Mojave, California for $15,000.
The companies plan to carry out the collection during already scheduled unmanned missions to the Moon in 2022 and 2023.
The firms are to collect a small amount of lunar soil known as regolith from the Moon and to provide imagery to NASA of the collection and the collected material.
Ownership of the lunar soil will then be transferred to NASA and it will become the “sole property of NASA for the agency’s use under the Artemis program.”
Under the Artemis program, Nasa plans to land a man and a woman on the Moon by 2024 and lay the groundwork for sustainable exploration and an eventual mission to Mars.
“The precedent is a very important part of what we’re doing today,” said Mike Gold, NASA’s acting associate administrator for international and interagency relations.
“We think it’s very important to establish the precedent that the private sector entities can extract, can take these resources but Nasa can purchase and utilize them to fuel not only NASA’s activities, but a whole new dynamic era of public and private development and exploration on the Moon,” Gold said.
“We must learn to generate our own water, air and even fuel,” he said. “Living off the land will enable ambitious exploration activities that will result in awe inspiring science and unprecedented discoveries.”
Any lessons learned on the Moon would be crucial to an eventual mission to Mars.
“Human mission to Mars will be even more demanding and challenging than our lunar operations, which is why it’s so critical to learn from our experiences on the Moon and apply those lessons to Mars,” Gold said.
“We want to demonstrate explicitly that you can extract, you can utilize resources, and that we will be conducting those activities in full compliance with the Outer Space Treaty,” he said. “That’s the precedent that’s important. It’s important for America to lead, not just in technology, but in policy.”
The United States is seeking to establish a precedent because there is currently no international consensus on property rights in space and China and Russia have not reached an understanding with the United States on the subject.
The 1967 Outer Space Treaty is vague but it deems outer space to be “not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.”
Chinese moon mission begins return to earth with lunar rocks – Global News
A Chinese spacecraft lifted off from the moon Thursday night with a load of lunar rocks, the first stage of its return to Earth, the government space agency reported.
Chang’e 5, the third Chinese spacecraft to land on the moon and the first to take off from it again, is the latest in a series of increasingly ambitious missions for Beijing’s space program, which also has an orbiter and rover headed to Mars.
The Chang’e 5 touched down Tuesday on the Sea of Storms on the moon’s near side. Its mission: collect about two kilograms (four pounds) of lunar rocks and bring them back to Earth, the first return of samples since Soviet spacecraft did so in the 1970s. Earlier, the U.S. Apollo astronauts brought back hundreds of pounds of moon rocks.
The landing site is near a formation called the Mons Rumker and may contain rocks billions of years younger than those retrieved earlier.
The ascent vehicle lifted off from the moon shortly after 11 p.m. Beijing time Thursday (1500 GMT) and was due to rendezvous with a return vehicle in lunar orbit, then transfer the samples to a capsule, according to the China National Space Administration. The moon rocks and debris were sealed inside a special canister to avoid contamination.
It wasn’t clear when the linkup would occur. After the transfer, the ascent module would be ejected and the capsule would remain in lunar orbit for about a week, awaiting the optimal time to make the trip back to Earth.
Chinese officials have said the capsule with the samples is due to land on Earth around the middle of the month. Touchdown is planned for the grasslands of Inner Mongolia, where China’s astronauts have made their return in Shenzhou spacecraft.
Chang’e 5’s lander, which remained on the moon, was capable of scooping samples from the surface and drilling two metres (about six feet).
While retrieving samples was its main task, the lander also was equipped to extensively photograph the area, map conditions below the surface with ground penetrating radar and analyze the lunar soil for minerals and water content.
Right before the ascent vehicle lifted off, the lander unfurled what the space administration called the first free-standing Chinese flag on the moon. The agency posted an image — apparently taken from the lander — of the ascend vehicle firing its engines as it took off.
Chang’e 5 has revived talk of China one day sending astronauts to the moon and possibly building a scientific base there, although no timeline has been proposed for such projects.
China launched its first temporary orbiting laboratory in 2011 and a second in 2016. Plans call for a permanent space station after 2022, possibly to be serviced by a reusable space plane.
While China is boosting co-operation with the European Space Agency and others, interactions with NASA are severely limited by U.S. concerns over the secretive nature and close military links of the Chinese program.

Massive telescope collapse caught on remote camera and drone in Puerto Rico – CBC.ca
The National Science Foundation (NSF) has released new footage of the collapse of the Arecibo telescope platform in Puerto Rico.
The 57-year-old radio telescope suffered major damage in August when one of the cables supporting the platform snapped. Another cable snapped in early November.
Then, on Tuesday, the entire platform came crashing 122 metres onto the dish below.
“We are saddened by this situation but thankful that no one was hurt,” NSF Director Sethuraman Panchanathan said in a statement. “When engineers advised NSF that the structure was unstable and presented a danger to work teams and Arecibo staff, we took their warnings seriously.”
The telescope has been used to track asteroids on a path to Earth, conduct research that led to a Nobel Prize and determine if a planet is potentially habitable. It also served as a training ground for graduate students and drew about 90,000 visitors a year.
“I am one of those students who visited it when young and got inspired,” said Abel Mendez, a physics and astrobiology professor at the University of Puerto Rico at Arecibo who has used the telescope for research. “The world without the observatory loses, but Puerto Rico loses even more.”
Arecibo has also been featured in movies such as Contact and the James Bond film GoldenEye.
