The Dirección General del Catastro Territorial (General Directorate
of Cadastre Land [DGCT]) of the Province of Formosa, Argentina, is
responsible for managing, maintaining, and updating the geographic
information and legal valuation of approximately 160,000 parcels that
make up the province, contributing to traffic safety, secure land
tenure, land-use planning, and urban financing through property taxes.
To continue to fulfill these responsibilities, it was necessary to have
reliable, high-quality land information that could be accessed easily
and efficiently.
Officials implemented a new GIS to address these needs and realize
their vision of having a digital cadastre that is open and allows
citizens easy access to the provincial land registry information. This
project involved new technological advances within the provincial
administration.

Math formula gives new glimpse into the magical mind of Ramanujan
Srinivasa Ramanujan. |
"I wanted to do something special, in the spirit of Ramanujan, to mark the anniversary," says Emory mathematician Ken Ono. "It's fascinating to me to explore his writings and imagine how his brain may have worked. It's like being a mathematical anthropologist."
Ono, a number theorist whose work has previously uncovered hidden meanings in the notebooks of Ramanujan, set to work on the 125th-anniversary project with two colleagues and former students: Amanda Folsom, from Yale, and Rob Rhoades, from Stanford.
The result is a formula for mock modular forms that may prove useful to physicists who study black holes. The work, which Ono recently presented at the Ramanujan 125 conference at the University of Florida, also solves one of the greatest puzzles left behind by the enigmatic Indian genius.

ESA's powerful new tracking station ready for service
Forty metres tall and with a moving antenna assembly weighing 610 tonnes, the station strikes a starkly beautiful pose 1500 m up on an arid Argentinian plain, where high tech meets the high Pampas. |
The massive radio reflector dish of ESA's new station is the most visible indication of the impressive technology that will soon track missions voyaging hundreds of millions of kilometres deep in our Solar System.
Forty metres tall and with a moving antenna assembly weighing 610 tonnes, the station strikes a starkly beautiful pose 1500 m up on an arid Argentinian plain, where high tech meets the high Pampas.
In addition to tracking missions at Mars and Venus, it can also conduct radio science experiments, allowing scientists in Europe and Argentina to study the matter through which the spacecraft-ground communication signals travel.

Beating Heart of J-2X Engine Finishes Year of Testing by Staff Writers
The powerpack assembly burned millions of pounds of propellants during a series of 13 tests totaling more than an hour and a half in 2012. The testing team set several records for hot-firing duration at Stennis test stands during the summer. |
The J-2X engine is the first human-rated liquid oxygen and liquid hydrogen engine developed in the United States in decades. Designed and built by NASA and industry partner Pratt and Whitney Rocketdyne of Canoga Park, Calif., the engine will power the upper stage of NASA's 143-ton (130-metric-ton) Space Launch System (SLS) rocket. The powerpack is a system of components on top of the engine that feeds propellants to the bell nozzle of the engine to produce thrust.

Exploding star missing from formation of solar system
Scientists in the University of Chicago's Origins Laboratory have published the latest in a series of papers about the origin of the solar system. Infant stars glow reddish-pink in this infrared image of the Serpens star-forming region, captured by NASA's Spitzer Space Telescope. Four and a half billion years ago, the sun may have looked much like one of the baby stars deeply embedded in the cosmic cloud of gas and dust that collapsed to create it. Credit: NASA/JPL-Caltech/L. Cieza (University of Texas at Austin). |
A new study published by University of Chicago researchers challenges the notion that the force of an exploding star forced the formation of the solar system. In this study, published online last month in Earth and Planetary Science Letters, authors Haolan Tang and Nicolas Dauphas found the radioactive isotope iron 60 - the telltale sign of an exploding star-low in abundance and well mixed in solar system material.
As cosmochemists, they look for remnants of stellar explosions in meteorites to help determine the conditions under which the solar system formed.
ISS Orbit Raised Ahead of Crew Arrival
International Space Station Expedition 34 will perform two spacewalks under the Russian and US space programs. |
The International Space Station's orbit has been increased by almost 2.5 kilometers in a test of the station's new emergency debris avoidance system, Mission Control told RIA Novosti.
The new system, known as the Pre-Determined Debris Avoidance Maneuver (PDAM), addresses the situation where dangerous debris is detected with little advance warning, down to as little as three hours from the approach.
The reboost was originally scheduled for Thursday, but had been postponed "after encountering some challenges latching down one of the Beta Gimbal Assemblies that rotate the station's huge solar arrays," NASA said on its website.

ChemCam is a science instrument on the mast of the Curiosity rover (Photo: NASA JPL). |
On August 6th, 2012 the automatic rover "Curiosity" landed on Mars. One of the scientific instruments on board is ChemCam, which has a pulsed laser capable of ablating a focused spot on a remote sample to create a glowing plasma plume of target's material. Light from plasma is collected by rover's telescope on a mast, and the optical spectra are then analyzed by an internal spectrometer.
ChemCam can take thousands spectra per day from a distance of about 7 meters, thus making chemical analyses on the surface of Mars with unprecedented speed. ChemCam has become the most frequently used instrument on the rover because of simplicity of its stand-off operation.
Station Crew Does Maintenance as Soyuz Rolls to Launch Pad
The Soyuz spacecraft that will carry Marshburn, Hadfield and Romanenko to the station was transported by railcar to the launch pad Monday after its three stages were mated together Sunday. |
Final launch preparations are under way at the Baikonur Cosmodrome in Kazakhstan as three Expedition 34 flight engineers get ready for their launch to round out the standard six-person crew on the International Space Station.
The three Expedition 34 crew members currently living and working aboard the station were busy with a variety of maintenance duties and science experiments Monday as they wait for the launch and arrival of their crewmates.
Commander Kevin Ford unpacked medical kit supplies brought to the station aboard the ISS Progress 49 cargo craft and packed trash and other unneeded items aboard the ISS Progress 48 cargo craft for disposal.

GRAIL Lunar Impact Site Named for Astronaut Sally Ride
The final flight path for NASA's twin GRAIL mission spacecraft to impact the moon on Dec. 17. GRAIL's MoonKAM is the signature education and public outreach program led by Sally Ride Science-founded by Dr. Sally Ride, America's first woman in space. |
NASA has named the site where twin agency spacecraft impacted the moon Monday in honor of the late astronaut Sally K. Ride, who was America's first woman in space and a member of the probes' mission team.
Last Friday, Ebb and Flow, the two spacecraft comprising NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, were commanded to descend into a lower orbit that would result in an impact Monday on a mountain near the moon's north pole. The formation-flying duo hit the lunar surface as planned at 2:28:51 p.m. PST (5:28:51 p.m. EST) and 2:29:21 p.m. PST (5:29:21 p.m. EST) at a speed of 3,760 mph (1.7 kilometers per second).

Imagine riding in an airplane as the plane is jolted back and forth by gusts of wind that you can't prove exist but are there nonetheless. Similar turbulence exists in space, and a research team led by the University of Iowa reports to have directly measured it for the first time in the laboratory.
"Turbulence is not restricted to environments here on Earth, but also arises pervasively throughout the solar system and beyond, driving chaotic motions in the ionized gas, or plasma, that fills the universe," says Gregory Howes, assistant professor of physics and astronomy at the UI and lead author of the paper to be published Dec. 17 in the online edition of Physical Review Letters, the journal of the American Physical Society.

No plans of sending an Indian on moon
India has no plans to put an astronaut on the moon, as of now. Minister of State in the Prime Minister's Office V Narayanasamy in the Rajya Sabha on Thursday said this.
The minister also said that the Indian Space Research Organisation (ISRO) had no plans in the immediate future to launch space labs and manned spaceships or set up space stations.
"However, ISRO has undertaken the development critical technologies required for manned missions in the Earth's orbit," he said in a written statement.

This past week, engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., received materials to begin manufacturing the adapter that will connect the Orion capsule to a United Launch Alliance Delta IV heavy-lift rocket for EFT-1. |
Recent engineering advances by NASA and its industry partners across the country show important progress toward Exploration Flight Test-1 (EFT-1), the next step to launching humans to deep space.
The uncrewed EFT-1 mission, launching from NASA's Kennedy Space Center in Florida in 2014, will test the re-entry performance of the agency's Orion capsule, the most advanced spacecraft ever designed, which will carry astronauts farther into space than ever before.
"These recent milestones are laying the foundation for our first flight test of Orion in 2014," said Dan Dumbacher, deputy associate administrator for exploration systems development at NASA Headquarters in Washington.
Asteroid Toutatis Slowly Tumbles by Earth
Watch a video of asteroid Toutatis as captured by NASA's Goldstone Solar System Radar |
Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have generated a series of radar data images of a three-mile-long (4.8-kilometer) asteroid that made its closest approach to Earth on Dec. 12, 2012.
The images that make up the movie clip were generated with data taken on Dec. 12 and 13, 2012. On Dec. 12, the day of its closest approach to Earth, Toutatis was about 18 lunar distances, 4.3 million miles (6.9 million kilometers) from Earth. On Dec. 13, the asteroid was about 4.4 million miles (7 million kilometers), or about 18.2 lunar distances.
The radar data images of asteroid Toutatis indicate that it is an elongated, irregularly shaped object with ridges and perhaps craters. Along with shape detail, scientists are also seeing some interesting bright glints that could be surface boulders.
China Makes First Asteroid Fly By
Chang'e-2 came as close as 3.2 km from Toutatis and took pictures of the asteroid at a relative velocity of 10.73 km per second. |
China's space probe Chang'e-2 has successfully conducted a maneuver in which it flew by the asteroid Toutatis, about seven million km away from the Earth.
Travelling in deep space, Chang'e-2 made the flyby on Dec. 13 at 16:30:09 Beijing Time (08:30"09 GMT), the State Administration of Science, Technology and Industry for National Defense (SASTIND) announced on Saturday.
The flyby was the first time an unmanned spacecraft launched from Earth has taken such a close viewing of the asteroid, named after a Celtic god.
It also made China the fourth country after the United States, the European Union and Japan to be able to examine an asteroid by spacecraft.

"NASA wanted to rule out any possibility of our twins hitting the surface anywhere near any of the historic lunar exploration sites like the Apollo landing sites or where the Russian Luna probes touched down," said David Lehman, GRAIL project manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif. |
The lunar twins of NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission have each completed a rocket burn that has sealed their fate. The burns modified the orbit of the formation-flying spacecraft. Over the next three days, this new orbit will carry the twins lower and lower over the moon's surface.
On Monday afternoon, Dec. 17, at about 2:28 p.m. PST (5:28 p.m. EST), their moon-skimming will conclude when a portion of the lunar surface - an unnamed mountain near the natural satellite's north pole - rises higher than their orbital altitude.

Apple Maps glitch could be deadly: Australian police
Australian police Monday warned motorists about using Apple Maps on the iPhone's latest operating system after rescuing several people left stranded in the wilderness, saying the errors could prove deadly.
Victoria state police said drivers were sent "off the beaten track" in recent weeks while attempting to get to the inland town of Mildura, being directed instead to the middle of a national park.
"Police are extremely concerned as there is no water supply within the park and temperatures can reach as high as 46 degrees Celsius (114 F), making this a potentially life threatening issue," police said in a statement.
Authorities said tests on the mapping system had confirmed that it lists Mildura, around 500 kilometres (310 miles) northwest of Melbourne, as being in the heart of the Murray Sunset National Park.
This is about 70 kilometres (43 miles) from its actual location.

Seeing stars, finding nukes: Radio telescopes can spot clandestine nuclear tests
File image: Very Large Array (VLA). |
In the search for rogue nukes, researchers have discovered an unlikely tool: astronomical radio telescopes. Ohio State University researchers previously demonstrated another unlikely tool, when they showed that South Korean GPS stations detected telltale atmospheric disturbances from North Korea's 2009 nuclear test.
Both techniques were born out of the discovery that underground nuclear explosions leave their mark-on the outer reaches of Earth's atmosphere.
Now, working with astronomers at the U.S. Naval Research Laboratory (NRL), they have analyzed historical data from the Very Large Array (VLA), a constellation of 27 radio telescopes near Socorro, New Mexico-and discovered that the VLA recorded a very similar pattern of disturbances during the last two American underground nuclear tests, which took place in Nevada in 1992.

Hoping to expand our understanding of auroras and other fleeting atmospheric events, a team of space-weather researchers designed and built NORUSCA II, a new camera with unprecedented capabilities that can simultaneously image multiple spectral bands, in essence different wavelengths or colors, of light.
The camera was tested at the Kjell Henriksen Observatory (KHO) in Svalbard, Norway, where it produced the first-ever hyperspectral images of auroras-commonly referred to as "the Northern (or Southern) Lights"-and may already have revealed a previously unknown atmospheric phenomenon.
Details on the camera and the results from its first images were published in the Optical Society's (OSA) open-access journal Optics Express.

Skybox Imaging (has successfully completed the simulated space environmental test of its first high-resolution imaging microsatellite. During the 16-day test campaign conducted at NASA's Ames Research Center in Moffett Field, Calif., the satellite was placed in a thermal vacuum chamber that accurately simulated the thermal and environmental conditions of low Earth orbit. Skybox evaluated the spacecraft's performance in a variety of operational modes.
This included a "day-in-the-life" test where the Skybox operations team simulated flying the spacecraft for 20 orbits. The test data collected was used to accurately correlate the detailed spacecraft thermal and power models and verify that all subsystems performed as expected.

S. Korea seeks to recover N. Korea rocket debrisSeoul (AFP) Dec 13, 2012 - South Korea's navy has launched a salvage operation in the Yellow Sea to retrieve debris from North Korea's long-range rocket launch, military officials said Thursday.The first stage of the North's Unha-3 rocket launched on Wednesday fell in the sea off the Korean peninsula, while the second splashed down east of the Philippines. "Our navy discovered what appeared to be a part from the first stage of North Korea's rocket in the Yellow Sea Wednesday afternoon," a defence ministry spokesman told AFP. "A salvage operation is now under way to retrieve it," he said, declining to give details. The chunk of the debris was found on the sea bed, some 160 kilometers (100 miles) west of the southwestern port of Gunsan, Yonhap news agency said, at a depth of around 80 meters (260 feet). Before its last rocket launch attempt in April -- which ended in failure -- North Korea had warned both Japan and South Korea that any effort to salvage debris from the rocket would be considered an "act of war". The warning was not repeated before Wednesday's launch. Pyongyang said its latest launch was a purely scientific mission aimed at placing a polar-orbiting earth observation satellite in space. Most of the world saw it as a disguised ballistic missile test that violates UN resolutions imposed after the North's nuclear tests in 2006 and 2009. The UN Security Council has condemned the launch and warned of possible measures over what the US called a "highly provocative" act. |
The satellite launched by North Korea's long-range rocket is in operational orbit, South Korea's defence ministry said Thursday, confirming the apparent success of Pyongyang's stated space mission.
The satellite sent into space by the North's Unha-3 rocket on Wednesday, is "orbiting normally", ministry spokesman
Raytheon wins DARPA contract to design new military imaging satellites
by Staff WritersTucson, AZ (SPX) Dec 14, 2012
For this contract, Raytheon has teamed with Sierra Nevada Corporation, University of Arizona and SRI International to assist with design work and eventually production. Next year, in phase two of the SeeMe program, the Raytheon team would build six satellites for ground testing. |
Raytheon was awarded a $1.5 million Defense Advanced Research Projects Agency (DARPA) contract for phase one of the agency's Space Enabled Effects for Military Engagements (SeeMe) program.
During the next nine months, the company will complete the design for small satellites to enhance warfighter situational awareness in the battlespace.
The SeeMe program will provide useful on-demand imagery information directly to the warfighter in the field from a low-cost satellite constellation launched on a schedule that conforms to Department of Defense operational tempos.

Charitum Montes: a cratered winter wonderland
The high-resolution stereo camera on ESA’s
Mars Express imaged the Charitum Montes region of the Red Planet on 18 June, near
to Gale crater and the Argyre basin featured in our October and November image
releases. The brighter features, giving the image an ethereal winter-like feel
in the colour images, are surfaces covered with seasonal carbon dioxide frost.
Charitum Montes are a large group of rugged
mountains extending over almost 1000 km and bounding the southernmost rim of
the Argyre impact basin. They can be seen from Earth through larger telescope
and were named by Eugène Michel Antoniadi (1870–1944) in his 1929 work La Planète Mars.
Annotated image
The images in this release all show the
region’s old and highly-sculpted terrain, pockmarked with many large craters,
all of which have been substantially filled in. The whole region is dusted with
brighter carbon dioxide frost.
Perspective view
Numerous smaller ‘pedestal craters’ can also
be seen in the 3D and 2D images. These are impact craters where the ejecta have
formed a higher relief above the surroundings. One striking example is visible
on the smooth plain to the lower right in the annotated image (Box A).
Topographic view
The ejecta surrounding pedestal craters form
erosion-resistant layers, meaning that the immediate vicinity around the crater
erodes more slowly than the surrounding terrain. The resistant ejecta layer is
largely untouched, forming the pedestal.
Perspective view
Another well-preserved example of a pedestal
feature surrounding an impact crater can be seen within the large, old and
heavily-degraded crater on the lower-left side of the annotated image (Box B).
In the centre of the 2D images and dominating the perspective images is a
crater some 50 km wide filled with thick sedimentary deposits.
These deposits appear to have been introduced
through one of several breaches in the northern crater rim (Box C in the
annotated image). Dendritic channels appear to emanate from a completely
filled-in crater in this region (Box D), at the periphery of the large crater’s
northern edge.
Within the large crater, near to where the
breach (C) in the crater wall occurred, though unconnected to this event, we
can also see a small dune field (Box E). A region of significant interest to scientists lies within the large crater towards the top left
of the first image (Box F). This crater shows a diverse range of filling
material, with layers of varying colour and texture.
Charitum Montes in context
The uppermost layer appears to be bright and
smooth, taking on the appearance of a relatively thin blanket with some impact
craters. This layer interfaces with the underlying darker layer via some very
sharply defined edges, possibly as a result of erosion. The underlying darker
material has a much rougher and mottled appearance, and planetary geologists
are still studying possible causes. To the left of the crater interior, another
layer of sediments clearly sets itself apart from the underlying strata, partly
forming flat-topped structures (Box G).
3D view
The complexity and diversity of some areas in
this winter wonderland would doubtless give Father Christmas a hard time in
finding somewhere safe to land, but images like these are giving planetary
geologists yet another fascinating region of the Red Planet to study.

Third Galileo satellite begins transmitting navigation signal
Europe’s third Galileo satellite has
transmitted its first test navigation signals back to Earth. The two Galileo
satellites launched last October have reached their final orbital position and
are in the midst of testing. The third Galileo Flight Model, known as FM3,
transmitted its first test navigation signal in the E1 band on 1 December, the
band being used for Galileo’s freely available Open Service interoperable with
GPS.
Then, on the morning of 4 December, the
satellite broadcast signals across all three Galileo bands – E1, E5 and E6.
Galileo is designed to provide highly accurate timing and navigation services
to users around the world. So the testing is being carried out in addition to
the standard satellite commissioning to confirm that the critical navigation
payloads have not been degraded by the violence of launch.
Galileo satellites
While the satellites are run from Galileo’s
Oberpfaffenhofen Control Centre near Munich in Germany and their navigation
payloads are overseen from Galileo’s Mission Control Centre in Fucino, Italy, a
separate site is used for the in-orbit testing.
Located in the heart of Belgium’s Ardennes
forest, Redu is specially equipped for Galileo testing, with a 15 m-diameter
S-band antenna to upload commands and receive telemetry from the satellite, and
a 20 m-diameter L-band dish to monitor the shape and quality of navigation
signals at high resolution. “This marked the very first time that a Galileo
payload was activated directly from ESA’s Redu centre in Belgium,” explained
Marco Falcone, overseeing the campaign effort as Galileo’s System Manager.
First FM3 test navigation signal
“We have now established an end-to-end setup
in Redu that allows us to upload commands generated from Fucino’s Galileo
Control Centre to the satellite payload whenever the satellite passes over the
station, while at the same time directly receiving the resulting navigation
signal through its main L-band antenna.
“The result is our operations are much more
effective, shortening the time needed for payload in orbit testing.” Operating
at an altitude of 23 222 km, the Galileo satellites take about 14 hours to
orbit our planet, typically coming into view of Redu for between three to nine
hours each day.
FM3's test team
The fourth Galileo flight model, FM4, was
launched together with FM3 on 12 October. The two satellites shared the same
Soyuz launcher from French Guiana. Both have now been manoeuvred into their
operational orbits: at the same altitude but in a different orbital plane to
the first two Galileos, launched in 2011, in order to maximise the global
coverage.
Now that FM3’s payload has been activated,
FM4 is set to begin transmitting test navigation signals later this month. The
first two satellites have already passed their in-orbit testing.

Where is NASA going? Expert panel says space agency isn’t quite sure, needs clear goals
WASHINGTON — NASA, the agency that epitomized
the “Right Stuff,” looks lost in space and doesn’t have a clear sense of where
it is going, an independent panel of science and engineering experts said in a
stinging report Wednesday.
The
report by a panel of the distinguished National Academy of Sciences doesn’t
blame the space agency; it faults the president, Congress and the nation for
not giving NASA better direction. At the same time, it said NASA is doing
little to further the White House’s goal of sending astronauts to an asteroid.
In one withering passage, the panel said NASA’s mission and vision statements
are so vague and “generic” that they “could apply to almost any government
research and development agency, omitting even the words ‘aeronautics’ or
‘space.’”
The
space shuttles were retired in 2011 and are now museum pieces. Few people are
paying attention to the International Space Station, and American astronauts
have to rely on Russian spaceships to get there and back. Meanwhile,
rocket-building is being outsourced to private companies, and a commercial
venture plans to send people to the moon by the end of the decade.
Academy
panel member Bob Crippen, a retired NASA manager and astronaut who piloted the
first space shuttle mission, said he has never seen the space agency so adrift.
He said that includes the decade between the end of the Apollo moon landings in
the early 1970s and the beginning of the shuttle program. “I think people (at
NASA) want to be focused a little more and know where they are going,” Crippen
told The Associated Press.
NASA
spokesman David Weaver defended the agency, saying in an emailed statement that
it has clear and challenging goals. He listed several projects, including
continued use of the International Space Station and efforts to develop a
heavy-duty rocket and crew capsule capable of taking astronauts into deep
space. John Logsdon, a space policy expert who advised the Obama campaign in
2008, said the panel’s report, which is more strongly worded than usual for the
academy, “rather fairly points its fingers at the White House.”
“There’s a general sense of disappointment
that the administration has not been more bold and visionary in setting out a

Year in space challenging but doable, astronaut says
Spending
a full year in the cramped confines of the International Space Station poses
psychological and physical challenges, but two crewmen set for launch in 2015
are ready to go. When astronaut Scott Kelly told his 9-year-old daughter he was
going to spend a full year aboard the International Space Station, she
exclaimed "awesome!"
When
cosmonaut Mikhail Kornienko told his wife the same thing, "she started
crying."But both men said Wednesday they were looking forward to blasting
off in March 2015 and spending a full year in orbit, serving as medical guinea
pigs to help scientists learn more about the long-term physical and
psychological impacts of extended, confined flights in the weightless
environment of space.

"I
personally think our ultimate destination, at least for a long time in our
planet's future, is getting to Mars," Kelly told CBS News. "And I
look at this as a step towards that." Alexey Krasnov, director of manned
space operations for Roscosmos, the Russian federal space agency, agreed,
saying through a translator "I hope this one-year duration expedition will
help us achieve these tasks."A flight to Mars, possibly in the 2030s, is
expected to take seven to 10 months, followed by a lengthy stay in the reduced
gravity of the Red Planet and then an equally long trip back to Earth.
Space
station astronauts and cosmonauts typically spend up to six months aboard the
international lab complex, and researchers are eager to find out how the
adaptation process might change -- and what might need to be done about it --
for longer-duration missions.
The
spaceflight duration record holder is cosmonaut Valery Polyakov, who spent 438
days aboard the Russian Mir space station in 1994 and 1995. The U.S. record for
the longest single spaceflight is held by astronaut Michael Lopez-Alegria, who
spent 215 days in space aboard the International Space Station in 2006-07.
But
the upcoming flight with Kelly and Kornienko will set a new record for NASA and
it will be the first to employ the full range of modern medical protocols and
research procedures over a 12-month period.
Igor
Ushakov, a senior medical researcher with the Russian space program, said
astronauts and cosmonauts already run a 7 percent risk of having a problem that
requires medical care after a six-month flight."So the risk will double,
so for at least one of the two it will be 14 percent for the yearlong
expedition," he said. "I would like to knock on wood that it won't
happen, the worst scenario. But the risk is increased, that's for sure."
Even
so, he reassured reporters, "the cosmonauts who were in space for a year
or more, they all are alive and well today."

Countdown begins to the next generation of satellites
Iridium
NEXT is expected to begin launching in 2015 and to be fully operational in
2017. Leading technology design and
development firm Cambridge Consultants has been selected by Iridium
Communications Inc. to play a key role in the deployment of Iridium NEXT, the
company's second-generation satellite constellation and the world's most
significant commercial space programme, which is expected to begin launching in
early 2015.
Cambridge
Consultants will spearhead subscriber equipment technology development for the
constellation, which will cover the entire globe. It will also provide input
into the broader satellite and ground infrastructure system design upon which
Iridium NEXT is being built.
The
Iridium network is the world's largest commercial satellite constellation.
Covering the 90% of the Earth that cellular and terrestrial networks don't
cover, Iridium is extending connectivity in places and ways never before
imagined - from aircraft tracking in Alaska to the rescue of a trapped
mountaineer in Antarctica.
Iridium
enables two-way, real-time, low-latency voice and data communications services
through small, reliable devices and applications that change the way
organisations and people are able to operate and live. Building on a decade of
innovative design and technology collaboration, Cambridge Consultants is
contributing to the Iridium NEXT technology roadmap through its unique
knowledge of the current system, as well as its experience in leading-edge mainstream
wireless technologies.
The
roadmap will provide Iridium customers with a new generation of feature
enhancements and other product benefits as the Iridium NEXT project moves
toward completion and beyond."The Iridium NEXT system will enable unmatched
wireless connectivity for people in every corner of the globe and with such a
significant undertaking comes a myriad of technology challenges," said
Scott Smith, executive vice-president, Technology Development and Satellite
Operations, at Iridium.
"It
is uncommon in this industry to find such an effective long-term design
partnership as the one we have with Cambridge Consultants, and we are pleased
to have them as a part of the Iridium NEXT Mission Team that is collaborating
to move this ambitious project from the design phase into reality."
With
the preliminary design phase of Iridium NEXT satellites completed earlier this
year, Cambridge Consultants is now embarking on the construction of prototype
communications equipment that will be used to verify the design and performance
of the Iridium NEXT system prior to the anticipated start of full construction
in 2013. Iridium NEXT is expected to begin launching in 2015 and to be fully
operational in 2017.
"We're
proud of our long history with Iridium, and our input to the Iridium NEXT
programme will help the company scale its business by maximising its return on
investment in this next-generation satellite network," said Richard
Traherne, head of the Wireless division at Cambridge Consultants.
"By
applying knowledge acquired through our years of work with Iridium, we will
ensure not only that the ground terminals and infrastructure for Iridium NEXT
are effective, but that performance and user experience take a significant step
forward and that flexibility is built in to enable exciting new features for
future users."

NASA-NOAA Satellite Reveals New Views of Earth at Night
WASHINGTON -- Scientists unveiled today an
unprecedented new look at our planet at night. A global composite image,
constructed using cloud-free night images from a new NASA and National Oceanic and
Atmospheric Administration (NOAA) satellite, shows the glow of natural and
human-built phenomena across the planet in greater detail than ever before.
Many
satellites are equipped to look at Earth during the day, when they can observe
our planet fully illuminated by the sun. With a new sensor onboard the
NASA-NOAA Suomi National Polar-orbiting Partnership (NPP) satellite launched
last year, scientists now can observe Earth's atmosphere and surface during
nighttime hours.
The
new sensor, the day-night band of the Visible Infrared Imaging Radiometer Suite
(VIIRS), is sensitive enough to detect the nocturnal glow produced by Earth's
atmosphere and the light from a single ship in the sea. Satellites in the U.S.
Defense Meteorological Satellite Program have been making observations with
low-light sensors for 40 years. But the VIIRS day-night band can better detect
and resolve Earth's night lights. The new, higher resolution composite image of
Earth at night was released at a news conference at the American Geophysical
Union meeting in San Francisco. This and other VIIRS day-night band images are
providing researchers with valuable data for a wide variety of previously
unseen or poorly seen events.
"For
all the reasons that we need to see Earth during the day, we also need to see
Earth at night," said Steve Miller, a researcher at NOAA's Colorado State
University Cooperative Institute for Research in the Atmosphere. "Unlike
humans, the Earth never sleeps." The day-night band observed Hurricane
Sandy, illuminated by moonlight, making landfall over New Jersey on the evening
of Oct. 29. Night images showed the widespread power outages that left millions
in darkness in the wake of the storm. With its night view, VIIRS is able to
detect a more complete view of storms and other weather conditions, such as
fog, that are difficult to discern with infrared, or thermal, sensors. Night is
also when many types of clouds begin to form.
"The
use of the day-night band by the National Weather Service is growing,"
said Mitch Goldberg, program scientist for NOAA's Joint Polar Satellite System.
For example, the NOAA Weather Service's forecast office in Monterey, Calif., is
now using VIIRS day-night band images to improve monitoring and forecasting of
fog and low clouds for high air traffic coastal airports like San Francisco.
According to Goldberg, VIIRS images were used on Nov. 26, the Monday after
Thanksgiving, to map the dense fog in the San Francisco Bay area that resulted
in flight delays and cancellations.
"It's
like having three simultaneous low-light cameras operating at once and we pick
the best of various cameras, depending on where we're looking in the
scene," Miller said. The instrument can capture images on nights with or
without moonlight, producing crisp views of Earth's atmosphere, land and ocean
surfaces. "The night is nowhere as dark as we might think," Miller
said. And with the VIIRS day-night band helping scientists to tease out
information from human and natural sources of nighttime light, "we don't
have to be in the dark anymore, either."
"The
remarkable day-night band images from Suomi NPP have impressed the scientific
community and exceeded our pre-launch expectations," said James Gleason,
Suomi NPP project scientist at NASA's Goddard Space Flight Center in Greenbelt,
Md.
