Geminid Explosions On Moon Visible To Amateurs
saskboy writes "The ET scanning project SETI@Home was wildly popular, and the mock project Yeti@Home much less so, but soon there will be a chance for the enthusiastic amateur astronomer to combine those two scanning techniques and spot explosions on the moon with simple telescope and camera equipment at home." From the article: "'On Dec. 14, 2006, we observed at least five Geminid meteors hitting the Moon,' reports Bill Cooke of NASA's Meteoroid Environment Office in Huntsville, AL. Each impact caused an explosion ranging in power from 50 to 125 lbs of TNT and a flash of light as bright as a 7th-to-9th magnitude star... 'The amazing thing is,' says Cooke, 'we've [caught explosions] using a pair of ordinary backyard telescopes, 14-inch, and off-the-shelf CCD cameras. Amateur astronomers could be recording these explosions, too.'... [NASA will] soon release data reduction software developed specifically for amateur and professional astronomers wishing to do this type of work. The software runs on an ordinary PC equipped with a digital video card. 'If you have caught a lunar meteor on tape, this program can find it.'" -
New Crater On Moon Caught On Video
From A Far Away Land writes "NASA has released a video clip of a meteorite striking the surface of the Moon. From the article: 'On May 2, 2006, a meteoroid hit the Moon's Sea of Clouds (Mare Nubium) with 17 billion joules of kinetic energy -- that's about the same as 4 tons of TNT," says Bill Cooke, the head of NASA's Meteoroid Environment Office in Huntsville, AL.'" -
Jupiter Gets New Red Spot
saskboy writes "The planet Jupiter is growing a new red spot. Jupiter is already well known for its Great Red Spot storm which is visible through modest backyard telescopes, so it will be interesting if this newer spot sticks around and grows. From the article: 'The official name of this storm is Oval BA, but Red Jr. might be better. It's about half the size of the famous Great Red Spot and almost exactly the same color. Oval BA first appeared in the year 2000 when three smaller spots collided and merged. A similar merger centuries ago may have created the original Great Red Spot, a storm twice as wide as our planet and at least 300 years old.'" -
Medical Translator Used Successfully
saskboy writes "Translations of medical questions posed by doctors to their patients were provided by a new Canadian designed computer called MedBridge. "Cantonese, Mandarin, Japanese, Portuguese, French, and Russian," are some of the languages the MedBridge can work with. CBC reports, "If a patient is deaf, the system can also translate into American Sign Language using video. The MedBridge system is already in use at hospitals in New York, Toronto and Halifax." Pretranslated questions are stored in the computer and the doctor chooses from the list of questions to ask. It's not quite a Universal Translator, but it should improve doctor-patient communication." -
CCD Image Sensor Inventors Win $500,000 Award
saskboy writes "CCD inventors were honoured this week. According to CBC News, "Willard Boyle, a Canadian scientist who helped invent the light-sensitive chip, accepted (the prestigious Charles Stark Draper Prize) in the U.S. on Tuesday. Boyle and George Smith will share the $500,000 US award for the invention of the "Charge-Coupled Device (CCD), a light-sensitive component at the heart of digital cameras and other widely used imaging technologies," the U.S. National Academy of Engineering said." Those other devices include the Hubble Space Telescope, and orthoscopic medical instruments. "Boyle and Smith came up with the idea for the device while working at Bell Laboratories in 1969. 'It was after maybe an hour's work,' Boyle recalled. 'We went over to the blackboard and we had some sketching there. We went down to our models lab and made one.'"" -
Moon Shadows Frustrate Astronauts
saskboy writes "Apollo Chronicles by NASA talk about moon shadows and how they are much darker than daytime shadows on Earth. This is because there is almost no light reflected from atmosphere molecules or secondary light sources like "earthshine". "It is very easy to see in the shadows after you adapt for a while," noted Armstrong. But, added Aldrin, "continually moving back and forth from sunlight to shadow should be avoided because it's going to cost you some time in perception ability." Working on the moon even in the daylight might present unique problems not typically encountered on earth, if visual coordination in a shadow riddled area is required for a task. Audio of the NASA article is also available." -
Mega Bloks Wins Supreme Court Battle Against Lego
saskboy writes "Canada's highest court ruled unanimously Thursday that Mega Bloks can continue to sell their Lego styled stackable blocks in Canada. CBC writes, 'The Supreme Court of Canada decision marks the end of a long-running trademark battle between the Montreal-based Mega Bloks and Denmark's Lego.'" -
Fireballs Awe Early November Skywatchers
saskboy writes "NASA reports that an unusual number of fireball meteor sightings have been reported recently, possibly due to the larger number of people being outside for Halloween trick or treating, and others looking for the highly visible planet Mars while it's in the planetary neighborhood. From the article: "On Oct. 30, for example, Bill Plaskon of Jonesport, Maine, was 'observing Mars through a 10-inch telescope at 10:04 p.m. EST when a brilliant fireball lit up the sky and left a short corkscrew-like smoke trail that lasted about 1 minute.' The physical cause of the fireballs in the sky are likely the Taurid meteor shower. According to the International Meteor Organization, the Taurid shower peaks between Nov. 5th and Nov. 12th. 'Earth takes a week or two to traverse the swarm. This comparatively long duration means you don't get spectacular outbursts like a Leonid meteor storm,' rather closer to 'one every few hours.'" These meteor sightings have also, of course, sparked UFO speculation. -
Fly To Mars In A Plastic Ship
saskboy writes "NASA reports that an old polymer may be the spaceship material of the future. Polyethylene is in household garbage bags, and it is also an effective solar radiation shield. I learned three years ago in astronomy class that polyethylene is used in the sleeping quarters on current orbiting space vehicles, but now NASA has developed a way to toughen the polymer into a product they call RXF1 which is 'even stronger and lighter than aluminum'. As you may know, radiation in space is currently a major obstacle to manned missions outside of the Earth's magnetic field, so better radiation shielding is essential to planned manned missions to Mars and beyond.

NASA Reveals Dust Devil Data from Mars
saskboy writes "NASA reports that Martian dust devils could be much more destructive than previously considered. You may remember this past April when it was revealed that whirlwinds actually helped the current rovers by cleaning accumulated dust from their solar cells which increased their energy collection efficiency. But after studying the mini-storms more, they realize that the dust and sand particles could cause static electricity discharges, also known as lightning. The high speed grains of sand blowing around at about 30 meters/second (70 miles per hour) are nothing to blink at either, since they can damage astronauts or equipment on the Martian surface. The height of a Martian dust devil can reach 10km (6 miles), which means it's more like the size of a terran tornado." -
NASA Notices New, Nasty Solar Storm Type
saskboy writes "Solar Storms generally aren't this bad, but in January unique conditions led to a "proton superhighway" that bombarded earth with fast moving protons that could have harmed astronauts caught without a radiation shield. "Scant minutes after the January 20th [2005] flare, a swarm of high-speed protons surrounded Earth and the Moon. Thirty minutes later, the most intense proton storm in decades was underway." Listen to the story here. Archives from the January storms are also available from SpaceWeather.com"
