The Christmas Eve spacewalk planned by NASA at the International Space Station should wrap up repair work on a faulty cooling line.
Mission Control said Monday that unless something goes awry, two astronauts ought to finish installing a new ammonia pump Tuesday, during this second spacewalk. NASA originally thought three spacewalks might be needed.
Astronauts Rick Mastracchio and Michael Hopkins removed the faulty pump Saturday. Everything went so well, they jumped ahead in their effort to fix the external cooling line that shut down Dec. 11.
A bad valve in the pump caused the breakdown, prompting the urgent series of spacewalk repairs.
The second spacewalk should have been Monday, but was bumped a day so Mastracchio could swap suits. He inadvertently hit the water switch in the air lock following Saturday's spacewalk, and engineers suspect water entered his suit. The suit needs to dry out for at least a week before being used again, said flight director Judd Frieling.
Saturday's water intrusion is unrelated to helmet leakage that almost drowned an Italian spacewalker in July.
Two of the three Russians crew members, meanwhile, will conduct a Moscow-directed spacewalk on Friday to install cameras and fresh experiments. It was planned long before the U.S. cooling system ran into trouble.
The sixth space station resident is Japanese and will assist from inside during Tuesday's U.S. spacewalk.
NASA has conducted a Christmas Eve spacewalk only once before, during a Hubble Space Telescope repair mission in 1999.
Mission Control said it expects no conflicts between the path of the space station and Santa's flight: "The skies are all clear," commentator Rob Navias observed from Houston.

The National Aeronautics and Space Administration (NASA) is the agency of the United States government that is responsible for the nation's civilian space program and for aeronautics and aerospace research.
President Dwight D. Eisenhower established the National Aeronautics and Space Administration (NASA) in 1958[5] with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.[6][7]
Since that time, most U.S. space exploration efforts have been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches.
NASA science is focused on better understanding Earth through the Earth Observing System,[8] advancing heliophysics through the efforts of the Science Mission Directorate's Heliophysics Research Program,[9] exploring bodies throughout the Solar System with advanced robotic missions such as New Horizons,[10] and researching astrophysics topics, such as the Big Bang, through the Great Observatories and associated programs.[11] NASA shares data with various national and international organizations such as from the Greenhouse Gases Observing Satellite.
From 1946, the National Advisory Committee for Aeronautics (NACA) had been experimenting with rocket planes such as the supersonic Bell X-1.[12] In the early 1950s, there was challenge to launch an artificial satellite for the International Geophysical Year (195758). An effort for this was the American Project Vanguard. After the Soviet launch of the world's first artificial satellite (Sputnik 1) on October 4, 1957, the attention of the United States turned toward its own fledgling space efforts. The U.S. Congress, alarmed by the perceived threat to national security and technological leadership (known as the "Sputnik crisis"), urged immediate and swift action; President Dwight D. Eisenhower and his advisers counseled more deliberate measures. This led to an agreement that a new federal agency mainly based on NACA was needed to conduct all non-military activity in space. The Advanced Research Projects Agency (ARPA) was created in February 1958 to develop space technology for military application.[13]
On July 29, 1958, Eisenhower signed the National Aeronautics and Space Act, establishing NASA. When it began operations on October 1, 1958, NASA absorbed the 46-year-old NACA intact; its 8,000 employees, an annual budget of US$100million, three major research laboratories (Langley Aeronautical Laboratory, Ames Aeronautical Laboratory, and Lewis Flight Propulsion Laboratory) and two small test facilities.[14] A NASA seal was approved by President Eisenhower in 1959.[15] Elements of the Army Ballistic Missile Agency and the United States Naval Research Laboratory were incorporated into NASA. A significant contributor to NASA's entry into the Space Race with the Soviet Union was the technology from the German rocket program led by Wernher von Braun, who was now working for the Army Ballistic Missile Agency (ABMA), which in turn incorporated the technology of American scientist Robert Goddard's earlier works.[16] Earlier research efforts within the U.S. Air Force[14] and many of ARPA's early space programs were also transferred to NASA.[17] In December 1958, NASA gained control of the Jet Propulsion Laboratory, a contractor facility operated by the California Institute of Technology.[14]
The most notable NASA activities are its space flight programs, both manned and unmanned. The latter can be either independent, carrying scientific equipment, or supportive, testing equipment for manned flights. In the beginning, NASAs missions focused on the space race with the Soviet Union, which won the first round, but later the United States took the initiative and won the final race to the Moon. The unmanned missions have until now explored most of our solar system. They have also brought telescopes for deep space exploration into orbit around the Earth together with satellites for studying Earth itself.
The rocket planes experiments started by NACA was taken a step further by NASA which used them as support for spaceflights, the first of which was one-manned and launched by military rockets. When the attention turned to reaching the Moon, the solution chosen was complicated but also the most economical. Supportive projects, both manned and unmanned were introduced and bigger rockets together with spacecraft and moon lander developed. The Moon landing and end of the space race meant a reduction of NASAs activities. Space stations of a more or less permanent nature, suggested already during the space race, were built and an international cooperation was introduced in an attempt to both bring nations together and at the same time share the high costs of space missions. In all, more than 100 manned missions have been made by NASA since 1958.[18]
The NACA XS-1 (Bell X-1) was followed by additional experimental vehicles, including the X-15 in cooperation with the US Air Force and US Navy. The design featured a slender fuselage with fairings along the side containing fuel and early computerized control systems.[19] When the spacerace began the main objective was to get a person into space as soon as possible, therefore the simplest spacecraft that could be launched by existing rockets was favored. This led to the choice of a small capsule spacecraft while rocket plane proposals like a modified X-15[20] were turned down.[21] Instead X-15 was used for development of techniques and equipment of value for the space missions. This included jets for changing the orientation of a spacecraft, space suits for astronauts and horizon definition for navigation.[22] Nearly 200 flights were made between 1959 and 1968 allowing NASA to collect data vital not only to the spacerace but also the design of the Space Shuttle.[19] The altitude record for X-15 was 354,200 feet (107.96km).[22]

Nasa astronaut Mike Hopkins is seen during the spacewalk in this photo courtesy of Nasa, received December 22, 2013. - Reuters pic, December 24, 2013.Two American astronauts prepared to step out today on a rare Christmas Eve spacewalk to wrap up repairs to the cooling system at the International Space Station, Nasa said.
The spacewalk is set to begin at 1210 GMT (8.10pm MYT), marking the second outing to replace an ammonia pump module whose internal control valve failed December 11.
"The two spacewalkers will retrieve a spare pump module from an external stowage platform and install it in the currently vacated slot to restore full cooling capability for the complex," Nasa said.
Nasa astronauts Rick Mastracchio, 53, and Mike Hopkins, 44, made swift work of their first spacewalk on Saturday, disconnecting and pulling out an old cooling pump which regulates the temperature of equipment at the orbiting space lab.
They managed to complete almost two days' worth of work in a single outing that lasted just five and a half hours, ending an hour earlier than planned.
However, a problem emerged with Mastracchio's spacesuit afterward, adding new concerns about the safety of the 35-year-old gear that astronauts wear to protect them.
NASA said "a small amount of water" entered the suit's cooling system after Mastracchio had re-entered the space station airlock at the end of the spacewalk.
"As a result, flight controllers decided to switch to a backup suit for Mastracchio for the next spacewalk."
The task of resizing a spare suit on board the ISS took an extra day, and postponed the spacewalk from its initially planned date of yesterday to today.

NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), a spacecraft that made the most comprehensive survey to date of asteroids and comets, has returned its first set of test images in preparation for a renewed mission.
NEOWISE discovered more than 34,000 asteroids and characterized 158,000 throughout the solar system during its prime mission in 2010 and early 2011.
It was reactivated in September following 31 months in hibernation to assist NASA's efforts to identify the population of potentially hazardous near-Earth objects (NEOs). NEOWISE also can assist in characterizing previously detected asteroids that could be considered potential targets for future exploration missions.
"NEOWISE not only gives us a better understanding of the asteroids and comets we study directly, but it will help us refine our concepts and mission operation plans for future, space-based near-Earth object cataloging missions," said Amy Mainzer, principal investigator for NEOWISE at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. "The spacecraft is in excellent health, and the new images look just as good as they were before hibernation. Over the next weeks and months we will be gearing up our ground-based data processing and expect to get back into the asteroid hunting business, and acquire our first previously undiscovered space rock, in the next few months."
Some of the deep space images taken by the spacecraft include a previously detected asteroid named (872) Holda. With a diameter of 26 miles (42 kilometers), this asteroid orbits the sun between Mars and Jupiter in a region astronomers call the asteroid belt. The images tell researchers the quality of the spacecraft's observations is the same as during its primary mission.
The spacecraft uses a 16-inch (40-centimeter) telescope and infrared cameras to seek out and discover unknown NEOs and characterize their size, albedo or reflectivity, and thermal properties. Asteroids reflect, but do not emit visible light, so data collected with optical telescopes using visible light can be deceiving.
Infrared sensors, similar to the cameras on NEOWISE, are a powerful tool for discovering, cataloging and understanding the asteroid population. Some of the objects about which NEOWISE will be collecting data could become candidates for the agency's announced asteroid initiative.
NASA's initiative will be the first mission to identify, capture and relocate an asteroid. It represents an unprecedented technological feat that will lead to new scientific discoveries and technological capabilities that will help protect our home planet. The asteroid initiative brings together the best of NASA's science, technology and human exploration efforts to achieve President Obama's goal of sending humans to an asteroid by 2025.
"It is important that we accumulate as much of this type of data as possible while the spacecraft remains a viable asset," said Lindley Johnson, NASA's NEOWISE program executive in Washington. "NEOWISE is an important element to enhance our ability to support the initiative."

NASA Scientists and Engineers Receive Presidential Early Career Awards
NIOSH has issued an updated strategic plan for protecting workers in applications involving nanotechnology. Protecting the Nanotechnology Workforce: NIOSH Nanotechnology Research and Guidance Strategic Plan, 20132016 updates the agencys 2009 strategic plan with knowledge gained from results of ongoing research, NIOSH says.
While nanotechnology offers the potential for tremendous improvement and advances in the development of commercial products that may benefit society, the unique properties of engineered nanoparticles also could pose health risks to workers, the agency explains in the strategic plan.
Increasing numbers of workers are potentially exposed to nanomaterials in research laboratories, startup companies, production facilities and operations where nanomaterials are processed, used, disposed or recycled, the agency explains in the plan. The challenge is to determine whether the nature of intentionally produced (engineered) nanostructured materials and devices presents new occupational safety and health risks. At the same time, there is a need to address how the benefits of nanotechnology can be realized while the risks are proactively minimized.
The NIOSH strategic plan defines nanotechnology as a system of innovative methods to control and manipulate matter at near-atomic scale to produce new materials, structures and devices. The National Science Foundation predicts that the global market for nanotechnology-related products will reach $3 trillion and employ 2 million workers in the United States by 2020.
Today, nanomaterials are found in hundreds of products, ranging from cosmetics to clothing to industrial and biomedical applications, NIOSH says. The potential benefits of nanotechnology are huge, and these benefits should be realized by society. However, there is ongoing concern that the full potential of the societal benefits may not be realized if research efforts are not undertaken to determine how to best manage and control the potential occupational safety and health hazards associated with the handling of these nanomaterials.
NIOSH notes that its strategic plan is the roadmap being used to advance basic understanding of the toxicology and workplace exposures involved so that appropriate risk-management practices can be implemented during discovery, development and commercialization of engineered nanomaterials.

NIOSH Updates Strategic Plan for Protecting Nanotechnology Workers
What is nanotechnology?
Nanotechnology is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers (nm), where unique phenomena enable novel applications not feasible when working with bulk materials or even with single atoms or molecules. A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick; a single gold atom is about a third of a nanometer in diameter.
Researchers seeking to understand the fundamentals of properties at the nanoscale call their work nanoscience; those focused on effective use of the properties call their work nanoengineering.
Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at the nanoscale.
The nanoscale is the dimensional range of approximately 1 to 100 nanometers. For more information, see What it is and How it Works.
A nanometer is one billionth of a meter. (A meter is 39.37 inches, or slightly longer than one yard.) The prefix nano means one billionth, or 10-9, in the international system for units of weights and measure. The abbreviation for nanometer is "nm."
For visual examples of the size of the nanoscale, see The Size of Nano.
Nanoscale materials have been used for over a millenium. For example, nanoscale gold was used in stained glass in Medieval Europe and nanotubes were found in blades of swords made in Damascus. However, ten centuries passed before high-powered microscopes were invented, allowing us to see things at the nanoscale and begin working with materials at the nanoscale.
Nanotechnology as we now know it began about 30 years ago, when our tools to image and measure extended into the nanoscale. Around the turn of the millennium, government research managers in the United States and other countries observed that physicists, biologists, chemists, electrical engineers, optical engineers, and materials scientists were working on overlapping issues emerging at the nanoscale. In 2000, the U.S. National Nanotechnology Initiative (NNI) was created to help these researchers benefit from each others insights and accelerate the technologys development.

What if wearing a small patch on your arm enabled the detection of an oncoming cold, allowing for treatment to deter the onset of symptoms?
This type of innovative nanotechnology-enabled patch would allow people to make predictive decisions about their day, week or even month. The benefits are far-reaching. Nano-enabled sensors could monitor the health of patients in their own homes or could help coaches know when to remove athletes from a game or practice based on warning signs of overexertion or injury.
Imagine what we can do if we could extend our systems capability to include the physiological monitoring of humans, said Scott Fouse, the director of Lockheed Martin Advanced Technology Laboratories. Not only could we monitor their health to aid in medical treatment, such as the case with warfighters, but we could also design our systems to optimize individual performance readiness, essentially closing the loop with the user.
In partnership with the Air Force Research Laboratory (AFRL) and General Electric (GE), Lockheed Martin is engineering a nano-enabled sensor that is small, lightweight and inexpensively produced. AFRL and Lockheed Martin will lead the application in the military arena while GE seeks to leverage the technology in the consumer and health industries.
Innovation is not exclusive to the invention of a technology. Employing new ways to engage partners gives GE, AFRL and Lockheed Martin the opportunity to develop new technology based on each organizations expertise and objectives from inception of the idea through engineering, design and future production.

The mission of the Department of Cellular and Molecular Medicine is to support and promote research and teaching in molecular cell biology in the School of Medicine at UCSD (University of California at San Diego). The Department was first established as an autonomous Division in 1990 and was departmentalized in 1999. It is one of only two basic science departments in the School of Medicine at UCSD (University of California at San Diego). It consists of 23 faculty, more than 100 postdoctoral scholars, ~50 graduate students and over 80 staff. The Department plays a major role in the teaching the medical student and graduate student curricula in molecular cell biology.Cell biology remains the central discipline for the postgenomic era. More than 50 years ago E. B. Wilson wrote, "The key to every biological problem must finally be sought in the cell." Nearly 150 years ago, Virchow in his famous book, Cellular Pathology wrote that "All diseases are reducible to active or passive disturbances in cells".
Today cell biology has become the central basic science discipline in Biomedical research and in medical practice. It bridges biochemistry and structural biology to clinical medicine. Modern day cell biologists have the unprecedented opportunity to understand basic cellular processes as well as their derangements in diseases in molecular termsoften referred to as Molecular Cell Biology and Molecular Medicine. Todays molecular cell biologists utilize information obtained from biochemistry, genetic, and molecular approaches as well as sophisticated morphological techniques such as deconvolution, confocal and video microscopy and electron microscopy to the study of basic problems in cell biology and molecular medicine. They also take advantage of insights gained from proteomics, genomics and bioinformatics analyses. With the mapping of the human genome, the challenge becomes to understand the role of individual proteins and genes in cell function and disease. Thus the challenging frontier for the postgenomic era is centered in modern molecular cell biology.
Graduate Studies at University of California at San Diego (UCSD) In the School of Medicine graduate training in cell biology is centered in the Biomedical Sciences Graduate Program where it constitutes one of the main areas of study. There are abundant opportunities within the department to investigate problems in modern molecular cell biology with investigators who are internationally recognized and working at the cutting edge of their discipline.

Depp undergoes an eerie transformation for this futuristic new sci-fi movie.
Johnny Depp is to undergo a cinematic transformation once again for new sci-fi thriller Transcendence. Directed by Wally Pfister, whose credits include Inception and The Prestige, the movie will star Depp as a scientist whose brain is uploaded to a supercomputer after his death.
Johnny Depp's New Film Sees The Actor Transformed Into An Automative Computer.
Will Caster (Depp) is a computer scientist at the forefront of artificial intelligence research, he is taken out by an anti-technology activist who stands against Caster's pioneering work into computer emotion. Determined not to die, the scientist and his wife Evelyn (Rebecca Hall) rush to find a way to upload his consciousness so that he can communicate even beyond the grave. However, not everybody is so sure of what will happen if they succeed, especially as Carter's mind begins to evolve.
Pfister's unnerving thriller explores a future of science without boundaries and the untold effect that merging robotics with human emotional intelligence can have upon mankind.
Watch The 'Transcendence' Trailer:
As an actor, Depp has been transformed into all manner of characters and creatures, from the Mad Hatter, to Willy Wonka to drunken pirate Jack Sparrow.
What about Johnny Depp's other new film, Mortdecai?
Transcendence will see him transformed into a highly intelligent computer in his first high-profile science fiction role alongside Morgan Freeman, Kate Mara, Cillian Murphy and Paul Bettany.
Not only is this sleek-looking movie the first solo-helmed project from Pfister, the director also calls upon rookie screenwriter Jack Paglen to produce a movie in the vein of Inception crossed with 2001: A Space Odyssey.
