Plastic phantom shows space travel may be safer than thought

A European Space Agency (ESA) experiment aboard the International Space Station (ISS) suggests that space travelers may have less to worry about when it comes to radiation ... thanks to a phantom. Called the Matroshka, the "phantom" is a plastic mannequin that is the key component of the first comprehensive study of the effects of radiation on astronauts on long-term space missions that indicates that the hazard may not be as severe as previously thought.

Of all the perils of space travel, the most pervasive as it is intangible is radiation. Each day that an astronaut spends outside the protective confines of the Earth's atmosphere brings an increased chance of cancer and other conditions. According to ESA, a person on the ground soaks up about 2.5 mSv/year, while an astronaut on the space station can receive up to 1 mSv/day. This is the reason the European Astronaut Corps limits its members to 500 mSv/year and 1Sv for an entire career. (Sv or sievert is a unit used to measure of the health effect of small amounts of radiation on the body).

Surprisingly, despite this awareness, very little is actually known about how exactly how much and what kind of radiation an astronaut is actually exposed to. It's to fill this gap that the Matroshka was sent to the ISS. Named after the famous Russian nesting dolls, it was built and operated by ESA in cooperation with Roscosmos and various European institutions, and was flown to the station in 2004. Its purpose was to measure the type and amount of radiation astronauts are exposed to both inside and outside the space station over a period of several years.

The Matroshka is technically a phantom. That is, a radiological doll designed as a stand-in for a human being while testing radiation equipment or, in this case, space radiation. It consists of a head and torso made of 33 horizontal cross sections of plastic, each measuring 2.5 cm (1 in) thick. Layers are used, so the mannequin can be assembled around a central dowel, which makes it easy to install and remove sensors. Each layer is made of a special plastic that simulates the soft tissues of the body with different densities standing in for the muscles, liver, spleen, lungs, and so forth. In addition, there are pieces of real human bone inserted into the cross sections to provide the proper radiological properties and a battery of sensors.

Space radiation is composed mainly of cosmic rays made up of protons and other heavy ions instead of the more common gamma rays found in terrestrial radiation sources. Since there are many different kinds of different radiation, so a number of different active and passive sensors are needed to detect them. The Matroshka includes about a dozen different sensors, including detectors for recording pressure and temperature.

Among the sensors are six thousand passive thermoluminescent detectors many of which were made by the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Krakw, Poland. They are constructed of doped lithium fluoride placed in plastic tubes set in a 3D lattice. The dopants upset the detector's crystalline structure, which sets up "forbidden" energy levels that capture electrons generated by cosmic rays. When the tubes are returned to Earth and heated in a laboratory, they release light in proportion to the amount of radiation they've absorbed.

Over the Matroshka is a not very fashionable jacket, which isn't just there for looks. It also acts as a mounting for cables and additional detectors. The latter need to be placed on the outside of the mannequin in order to measure incoming radiation and skin exposure, and to simulate the dosimeters carried by all space station personnel.

From 2004 to 2009, the Matroshka sat inside one of the Russian modules on the ISS, but radiation hazards outside the station are many times greater than inside, so the phantom made a spacewalk for the first such exposure measurements ever made. Like a human astronaut, the Matroshka was clad in a spacesuit or, at least, a simulated one made of layers of carbon fiber and plastic and filled with dry oxygen gas.

ATV views Space Station as never before

ESA's fifth and last Automated Transfer Vehicle tested a new technique before docking with the International Space Station in August, at the same time revealing the orbital complex in a new light.

ATV Georges Lemaitre demonstrated a set of European sensors that offers future improvements on the autonomous rendezvous and docking that these ferries have completed five times since 2008. ESA's goal is to perform an automated rendezvous further from home - perhaps near Mars or with an 'uncooperative' target such as an inert object.

Seeing through an eclipse During Georges Lemaitre's rendezvous using its proven system, the Laser Infrared Imaging Sensors, or LIRIS, experiment was turned on some two and a half hours and 3500 m from the Space Station. All of the sensors worked as expected and a large amount of data was recorded and stored on hard disks in ATV's cargo hold.

The disks were retrieved by ESA astronaut Alexander Gerst on 29 August and returned to Earth in Soyuz TMA-12M in September. The information is now being compared against the results from ATV's normal navigation sensors.

With ATV-5 pointing directly at the Station, the LIRIS infrared cameras tracked the weightless research centre perfectly despite several 30-minute periods in darkness when the Sun was eclipsed by Earth and traditional cameras would have gone blind.

The image above was taken 70 m from the Station - the first showing the complex in this configuration. Ahead of an ATV docking, the Station turns its solar wings to avoid GPS navigation signals bouncing off the structure and confusing the incoming craft.

Four days before docking, ATV flew 7 km below the Station to check the long-range capability of the infrared cameras. A first look at the readings confirms LIRIS' ability to track targets from a distance.

Laser Radar LIRIS includes a lidar - like a radar but using light - that pulses laser beams over a mirror to collect 3D data at high resolution. The lidar also registers the amount of reflected light, which can provide clues on the type of material it is scanning.

Russia's Zvezda module, where Georges Lemaitre now sits, shows up in green from 30 m, while the Soyuz was 15 m further away (yellow). The Station's main truss is in purple, 40 m from Zvezda.

The image on the right was created from the same data but shows how much light was reflected from each point. The Station's retroreflector used for ATV's normal laser docking sensors shows up brightly, just as the designers intended.

OPALS: Light Beams Let Data Rates Soar

You may know opals as fiery gemstones, but something special called OPALS is floating above us in space. On the International Space Station, the Optical Payload for Lasercomm Science (OPALS) is demonstrating how laser communications can speed up the flow of information between Earth and space, compared to radio signals.

"OPALS has shown that space-to-ground laser communications transmissions are practical and repeatable," said Matthew Abrahamson, OPALS mission manager at NASA's Jet Propulsion Laboratory in Pasadena, California.

"As a bonus, OPALS has collected an enormous amount of data to advance the science of sending lasers through the atmosphere. We look forward to continuing our testing of this technology, which sends information to and from space faster than with radio signals."

Laser communication science has Earth benefits, too. Faster downlinks from space could mean people receive higher-definition video from both satellites orbiting our planet and spacecraft farther into space, including NASA's Mars rovers. Laser communication technology also has the potential to provide faster Internet connections in remote areas on Earth. Anyone with an interest in high-speed, high-quality downloads may benefit from this technology -- including researchers, engineers and consumers.

OPALS has completed its four-month prime mission. In the next phase of the mission, OPALS scientists will look at how adaptive optics can increase the efficiency of the optical communications link. The lessons learned from OPALS will make future optical links more robust and reliable.

OPALS launched to the space station aboard a SpaceX Dragon cargo capsule in April. The payload was able to establish an optical communications link when its laser locked onto a ground beacon emitted by the Optical Communications Telescope Laboratory's ground station at JPL's Table Mountain Observatory in Wrightwood, California. The technology uses a beacon with four individual lasers to average the effects of atmospheric turbulence.

"Four lasers from the ground station travel through the sky toward the space station. Under clear, dark background conditions, it's very easy for the payload to acquire the ground beacon. Daylight conditions have proven more challenging, but we are working on increasing capabilities during the day as well, through software enhancements," Abrahamson said.

OPALS had 18 successful passes from Table Mountain: nine during daylight and nine during nighttime. The payload was able to track the ground receiver with stunning accuracy.

"At times, weather was a challenge, with clouds obscuring the lasers. The payload showed the capability to reacquire the signal after cloud blockage," Abrahamson said.

OPALS had its first success on June 5, a night pass lasting 148 seconds. It sent a copy of the same video (with the message, "Hello, World!") every 3.5 seconds. With traditional downlink methods, the 175-megabit video would take 10 minutes to transmit.

Weve seen a vital telescope undergo repairs, an emergency replacement of part of a space stations cooling system, and even a tree made of food cans. Learn more about these fun holiday times below.

Reading from above the moon (Apollo 8, 1969)

In this famous reading from the Bible, astronauts Frank Borman, Jim Lovell and Bill Anders shared their experience looking at the Moon on Dec. 24, 1968. The Apollo 8 crew was the first to venture to lunar orbit, just seven months before the Apollo 11 crew made it all the way to the surface.

Era of in-space manufacturing starts as NASA creates first 3D printed object in space

Astronauts on the International Space Station (ISS) no longer have to wait for a delivery from Earth if they are missing some gizmo in space. With the addition of a 3D printer aboard the space station they may now make a certain number of components themselves.

In November, NASA created history by successfully 3D printing the first object in space. An additive manufacturing device, or 3D printer, was turned on, and initiated the first official 3D print on the ISS. Developed in partnership with NASAs Marshall space flight center and Ames research center, the project takes a step towards commercially and sustainably fabricating objects off of our planet.

The first print job was a small plate for mounting the 3D printer extruder print head that is the important part of the printer where the plastic material is heated and becomes liquid, so it can be squeezed out of a small nozzle. When the layer after layer of plastic placed on top of each other, 3D objects slowly becoming the reality.

After doing an initial calibration, engineers on the ground sent commands to the printer to make its first object. This first print serves to demonstrate the potential of the technology to produce replacement parts on demand if a critical component fails in space. The printer will be controlled from the control center on Earth that sends print jobs up and tells the astronauts when the object is ready for pickup.

This first print is the initial step toward providing an on-demand machine shop capability away from Earth, Niki Werkheiser, project manager for the International Space Station 3-D Printer project, said in a statement. The space station is the only laboratory where we can fully test this technology in space.

The plate says MADE IN SPACE and the logo of NASA were printed without problems, though the plastic was something better to the tray print than expected. If the printer works as planned, astronauts will be able to make simple things based on instructions from the ground.

As NASA ventures further into space, whether to redirect an asteroid or sending humans to Mars, the space agency needs transformative technology to reduce cargo weight and volume. In the future, perhaps astronauts will be able to print the tools and components they need in space. NASA hopes that astronauts will be able to print a variety of spare parts and tools to be used in space, and which would otherwise take a long time and cost for the sendoff from Earth.

This is the first time weve ever used a 3D printer in space, and we are learning, even from these initial operations, Werkheiser said. As we print more parts, well be able to learn whether some of the effects we are seeing are caused by microgravity or just part of the normal fine-tuning process for printing. When we get the parts back on Earth, well be able to do a more detailed analysis to find out how they compare to parts printed on Earth.

NASA says the space station will be a good spot to test this kind of stuff out. Additive manufacturing with 3-D printers will allow space crews to be less reliant on supply missions from Earth and lead to sustainable, self-reliant exploration missions where resupply is difficult and costly. The space station provides the optimal place to perfect this technology in microgravity.

The first 3D printed objects built in space will be returned to Earth in 2015 for detailed analysis and comparison to identical ground control samples. The goal of this analysis is to verify that the 3-D printing process works the same in microgravity as it does on Earth.

Marshall Center Hosts Mentor-Protege Agreement Signing Between Jacobs, Linc Research

Executives of technology firms Jacobs and Linc Research Inc., both in Huntsville, Alabama, will sign a NASA Mentor-Protg Agreement on Dec. 11 at NASAs Marshall Space Flight Center in Huntsville.

The signing will be held at 10 a.m. in Building 4200, Conference Room 900, at the Marshall Center. Speakers will include Chris Singer, director of the Marshall Center's Engineering Directorate; Kim Whitson, director of Marshall's Office of Procurement; Randy Lycans, vice president and general manager of Jacobs; Curtis Taylor, president of Linc Research; David Brock, small business specialist in Marshall's Office of Procurement; and T.K. Pendergrass, a Marshall contracting office representative. Members of the news media are invited.

The 12-month agreement is the second of its kind overseen by the Marshall Center, fostering a partnership between a NASA prime contractor and a certified Historically Underutilized Business Zone small business. The federal "HUBZone" program is designed to promote job growth, capital investment and economic development for small businesses in economically challenged communities.

Jacobs, headquartered in Pasadena, California, has been a NASA partner for more than 40 years, and currently supports the U.S. space program in a variety of capacities at NASA centers around the country. It notably holds the Manufacturing Support and Facility Operations Contract at NASA's Michoud Assembly Facility in New Orleans, where NASA built and assembled the Orion crew vehicle which completed its first test flight on Dec. 5 -- and also is building the core stage of the Space Launch System, the heavy-lift vehicle which soon will loft Orion crews into the solar system. Jacobs also manages and implements ground systems operations, flight hardware processing and launch operations at NASA's Kennedy Space Center, Florida, where the Space Launch System and Orion will be launched to space to pursue new missions of discovery at Mars and other destinations.

"Rudolph the Red-Nosed Reindeer" celebrates 50th anniversary on CBS

"Rudolph the Red-Nosed Reindeer" started out as a song made famous by Gene Autry, but he came to life in an animated special that has charmed generations. On Tuesday, Rudolph will run for the 50th straight year.

For a Christmas special to be a classic, it has to have cross-generational appeal, so CBS News assembled what you might ordinarily call a focus group -- though "focus" is probably the wrong word for the young bunch.

And it appears "Rudolph the Red-Nosed Reindeer" passes that test with flying -- and glowing -- colors.

First airing in 1964, "Rudolph the Red-Nosed Reindeer" was the creation of Arthur Rankin and Jules Bass, using a technique they called "animagic."

"The Rankin-Bass characters are just fun," New York Magazine TV critic Matt Zoller Seitz said. "Their bodies and their heads don't match up. Their movements are very awkward and strange."

"They weren't Disney, they weren't trying to be. But there's an incredible amount of artistry that goes into it," he added.

Filmed in Japan, Rudolph employs the oldest form of film animation, also known as stop motion. Movement is created by adjusting flexible dolls in tiny increments and shooting them frame by frame.

"It feels homemade to the point where generations of children were inspired to try to do their own versions of it with their action figures and bendable figurines and things like that," Zoller Seitz said.

Rudolph has influenced a number of contemporary filmmakers from Tim Burton to Wes Anderson.

"Over my years, my being involved in stop motion, I think that I came to appreciate the purity, the simplicity of Rudolph," Oscar-nominated director Henry Selick said.

Mangaluru: Red Bricks adds more beauty to city with two prestigious projects

Daijiworld Media Network - Business

Mangaluru, Dec 9: The identity of Dakshina Kannada is closely associated with the laterite stones, found abundantly in this coastal region. That is why when an enterprising trio of three brothers Rajesh, Sudesh and Shailesh and ably supported by their father Keshav Sujir decided to make a grand entry into the crammed real estate field of Dakshina Kannada he named his company as Red Bricks.

The name really caught the fancy of the people as it was the first company that came out with budget apartments, something unheard of in Mangalore. With its entry into real estate field in 2011 Red Bricks Dwelling and Infra Project Pvt Ltd, promoted by a Mumbai based Mangalorean created quite a flutter and revolutionised the real estate industry in Mangalore with its new-fangled approach by catering to a segment hitherto uncared for and marginalised.

The company found a strong pedestal in Mangalore with its daring approach. With land prices zooming Mangaloreans who are used to living in independent bungalows and huge houses slowly began accepting the apartment culture. But the existing builders focused more on promoting 2 and 3 bhk luxury flats to acclimatise people to the apartment way of life. This trend led to a void as these apartments are beyond the reach of lower middle class and the common people. But then there was a paradigm shift in the scenario with the entry of Red Brick with their two ambitious projects - Red Bricks Palm Hills at Kulshekar Chowky and Red Bricks Village at Silver Gate in Kulshekar.

Trendsetters in affordable apartments

The entry of Red Bricks offering affordable apartments created dj vu among the otherwise dejected people. Having sensed the existing void Red Bricks, which was always itching to do something tangible in its birth place Mangaluru, bought two prime properties in Mangalore to give wings to their dreams. It has been my fathers dream to give something to the working class people of this district. He had come up in a hard way and we can very well relate to the common people and their difficulties, says Rajesh Sujir the eldest of the three brothers.

NDRRMC, Red Cross clash over 'Ruby' death count

MANILA - Disaster officials and the Philippine Red Cross are at odds over the actual number of fatalities left behind by tropical depression "Ruby."

On Tuesday, the National Disaster Risk Reduction and Management Council's official death toll due to "Ruby" rose to 8, with fatalities coming from Regions 4-A (Calabarzon), 4-B (Mimaropa), 7 (Central Visayas) and 8 (Eastern Visayas).

The NDRRMC removed from its tally the two deaths in Iloilo, which were caused by hypothermia.

The council also defended its slow tally on casualties from "Ruby", which is lower than the Red Cross' own count of at least 22 fatalities.

"Convinced naman kami na namatay e pero dapat alam namin kung may certificate na ba yan, kung namatay yan dahil sa bagyo," NDRRMC executive director Alexander Pama said.

"During past typhoon, ang tanong natin bakit mabagal. Dapat official yan. Baka sabihin ng tao, ito ako buhay na buhay."

On the other hand, Red Cross Chairman Richard Gordon said he stands by the organization's own tally and will not argue with government officials about their own official list.

"We are in the business of saving lives. Gusto nila zero casualty, but that's impossible. I commend that, that's good. We should try to aim high but at the same time, gusto nila DOH pa ang mag-ve- verify," he said.

"Kami, kapag nakakita kami ng patay, we are trained to handle the dead."

Included in the Red Cross' own count are four members of the Amuyo family who drowned in Borongan, Eastern Samar, and a certain Epifanio Jardenia from the same barangay.

Red Light Jihad Thailands new breed of Facebook jihadis

Global Post Tuesday 9th December, 2014

Photo of jihadi holding a soldiers severed head by the hair: 403 shares.

Death threat against a Thai college student accused of insulting Islam: 150-plus comments, many of them clamoring for her beheading.

Thailands jihadis are often compared to ghosts. Theyre notoriously mysterious - a network of underground cells that strike suddenly and vanish into the jungle. Unlike the braggarts of al-Qaeda or the Islamic State, these fighters operate under a strict code of silence.

Or at least they used to.

These days, the ghosts are chattering on Facebook. Their Timelines are terrifying, gorier than snuff films. They post photos taken in the aftermath of grisly roadside bomb strikes. They single out Thai soldiers by name and call for their heads.

"Now youre finished, you dickless pig in a skirt," writes one self-proclaimed jihadi in a death threat, written in Thai. "Siamese pig" is their go-to insult for Thai troops.

They show off buckets full of 5.56mm bullets. Thats the caliber of ammo used by their weapon of choice: M-16s stolen from slain Thai troops. Under one close-up photo of assault rifle ammo, a jihadi asks, "Any pigs wanna suck on these?"

Their interests appear incongruous at times - hinting at youthful zeal rather than seasoned focus. Images of beheadings mingle with cat photos. The militants "likes" include pages devoted to Quranic scri...
