Don"t Blame Your Lousy Night"s Sleep On The Moon — Yet
From madness to seizures, to crime and lack of sleep, people have long blamed the full moon for a range of problems. Research, on the other hand, has found little evidence over the years to support these anecdotal accounts of the moon’s powers over the human body and brain.
But scientists in Switzerland decided to look again at one of those putative effects — disturbed sleep — and were surprised to see there might be something to the claim after all.
Scientists have a new hint of evidence that a full moon can disturb sleep. (And not just because it’s romantic.)

Christian Cajochen, who studies circadian rhythms and sleep at the University of Basel, says many friends who work in big sleep clinics tell him their patients sometimes complain of not being able to sleep during a full moon. Over drinks one day, he and some colleagues realized they already had some data that could put that long-held bit of folklore to a test.
“We were sitting outside a pub, and we were looking at the full moon,” Cajochen remembers, when they hatched their plan. In an unrelated earlier study, the scientists had collected detailed observations on the sleep patterns of some 30 healthy people — young and old, men and women — as they spent three days sleeping in a lab at various times of the month. The sleepers had been in light-controlled rooms, so were shielded during the study from any changes in daylight — or moonlight — outside the lab, and hadn’t been asked anything at all about the moon.
In their current study, published this week in Current Biology, Cajochen and his colleague looked back at that old data set and did some number crunching to compare how the people slept at different stages of the lunar cycle.
“We found that people who entered the lab during a full moon slept, on average, 20 minutes less than people who came in during the new moon phase,” Cajochen says. Deep sleep was also significantly reduced among people who were in the lab during a full moon, versus those at the lab during a new moon. And the sleep-inducing hormone, melatonin also declined during a full moon.
Though the results were statistically significant, Cajochen says they might not hold up in a much larger study. And until and unless he or others can replicate the findings and figure out a proposed mechanism for how the moon might have this effect, Cajochen says he’s “still skeptical.”
So’s Fred Turek, a chronobiologist at Northwestern University. “Extraordinary claims require extraordinary evidence,” Turek says, adding that the new study falls far short of providing that evidence.
“We don’t know whether humans have a clock mechanism that allows us to synchronize our physiology to the lunar cycle,” agrees Frank Scheer, a sleep researcher at Harvard Medical School. On the other hand, Scheer says, we know a lot about human circadian clocks, which program our bodies to the daily rhythms of day and night. We know where that clock is located in the brain and we understand the some of the neural and molecular pathways involved.
And until someone finds a lunar clock in humans, the mystery of the moon’s effect may just be something we have to sleep on.

Private Company To Put A Telescope On The Moon
Lunar citizen science by 2016!
Posted 07.19.2013 at 4:45 pm
International Lunar Observatory International Lunar Observatory Association/Moon Express, Inc.
Private space exploration is coming to the Moon, and soon. The world’s first mission to the Moon’s sunny South Pole will put a private telescope on a the lunar peak Malapert Mountain as early as 2015.
Moon Express, a private ‘lunar commerce’ startup, and the International Lunar Observatory Association, a nonprofit devoted to moon observation, have teamed up to put the International Lunar Observatory, a 2-meter radio antenna, on the Moon to observe the galaxy without the interference of Earth’s atmosphere, which absorbs some kinds of radiation.
ILOA plans to start small, establishing a scientific presence on the Moon, and eventually move on to human exploration and settlement. A preliminary mission with a smaller telescope will launch in 2015.
The full observatory, slated to arrive in 2016, would provide “scientific research, commercial broadcasting and [enable] Galaxy 21st Century education and “citizen science” on the Moon,” according to a press statement from the two organizations. Its access and controls will be available via the Internet to the general public, as well as researchers.
Moon Express will also send a small rover to prospect for resources, including metals, minerals and water, that could be extracted from the lunar surface and one day sold on Earth.
Though the timeframe for getting the observatory to the Moon has been described as a bit ambitious–even by the Moon Express CEO Bob Richards, according to Wired–Moon Express is in the running for Google’s Lunar XPRIZE to land a robot on the lunar surface by 2015.

Astronomers Want To Fire Giant Bullets At Jupiter"s Moon Europa
Hey aliens, you have about 10 years to reveal yourselves before we launch a science missile.
Posted 07.16.2013 at 4:00 pm
Scientists at University College London have designed a 44-pound bullet that could gather scientific information on Jupiter’s moon Europa. Last week, a prototype of the bullet slammed through a 10-tonne block of ice, an important test for a future mission to the icy moon. Now, the European Space Agency has decided to throw its weight behind the odd project.
The penetrator (yep, that’s its name. Moving on…) would launch from a satellite orbiting Europa and lodge itself a few meters into the moon’s ice. Despite its militaristic appearance, the penetrator is really a research vessel designed to carry seismometers and other scientific equipment. These sensors could relay information back to the satellite and, from there, back to Earth. Multiple penetrators could be fired from a single satellite, covering Europa in ballistic impact wounds and scientific collection tools, which combined would paint a more complete picture of the moon.
Bullet-carried sensors have limitations: size constraints, a lack of mobility, and likely a very limited lifespan while on the surface of the moon. They make up for that, however, by not needing the elaborate soft landing systems designed to protect more sensitive explorers, like the Mars rover Curiosity.
The technology is expected to take a decade to develop fully, but when it does, it might finally answer one of the great mysteries of our solar system: is there life below the ice of Europa? (And if so, how does it feel about being shot at by bullets?)

Happening Now: An Asteroid And Its Moon Sail Past Earth
The pair will come their closest at 4:59 pm ET today.
Posted 05.31.2013 at 4:00 pm
First Radar Images of 1998 QE2 NASA/JPL-Caltech/GSSR
An asteroid is sailing past Earth today, and it’s bringing along some luggage.
At 4:59 pm ET, asteroid 1998 QE2 will be a mere 3.6 million miles away from our home planet. And it’s not alone. It is bringing with it a moon that orbits it as it flies along its own path.
Okay, “mere” is an exaggeration. It will come to about a distance that’s 15 times the distance between the Earth and the moon. The asteroid is not a threat to Earth, NASA says.
Astronomers first discovered 1998 QE2 in 1998, hence its name. They only discovered that it had an orbiting moon on May 29, however, when radar images showed the moon as a smudge by its side. Among asteroids near Earth, only 16 percent that are 200 meters (655 feet) in diameter or larger are made up of two or three pieces that travel in tandem, called binary or triple asteroids. The new radar images suggest 1998 QE2 is 1.7 miles in diameter. Its moon is 2,000 feet wide.
The pair will not get this close to Earth again for another 200 years.
Over the next week, astronomers using the Deep Space Network antenna in Goldstone, California, and the Arecibo Observatory in Puerto Rico will observe 1998 QE2 as it comes by. Radar helps astronomers discern asteroids’ shapes, rotation, surface features and orbits. Such observations are a part of NASA’s larger effort to learn about asteroids so it can predict when any do threaten Earth–although, of course, we’re not always the greatest at that quite yet.
