NASA Train Like An Astronaut - Do A Spacewalk Activity
NASA astronauts explain why muscular strength and coordination are needed to successfully pull and push objects during a spacewalk, and an astronaut trainer shows how to set up the course and correctly perform the two movements in this activity. How could you perform a physical activity that would improve increase muscular strength, as well as improve upper and lower body coordination? Many activities require strength to support weight, and coordination to support weight and move without falling over. When riding a skateboard, doing push-ups, crawling across the ground, or lifting a backpack, you are developing muscular strength and coordination.

NASA 2013 " THE BIGGEST SOLAR STORM" PROPHECY. AR 1654-1652 EARTH(END OF THE WORLD) XXI CATACLYSM
January 14, 2013. The AR Sunspot 1654 is growing and being active which has produced M-class solar flares. Experts from the National Oceanic and Atmospheric Administration (NOAA) remain on the alert for a huge sunspot detected two days ago on the Sun #39;s surface.Called AR 1654, the spot is 10 times larger than Earth and moves slowly, but according to the solar rotation in a few days it will point to the earth #39;s surface, said researchers, who also consider intense flares may occur. For sure the phenomenon will generates M class flares, but there have not been ruled out some class X flares, which are the largest according to the existing classification, they said. According to the website SpaceWeather.com, AR 1654 "could be the sunspot to break the recent and long period of calm in space weather around our planet."

NASA's U-2 Clandestine Cover Story
On May 1, 1960, Gary Powers U-2 was shot down over Sverdlosk in the Soviet Union. When he heard the news, the pilots fate wasnt President Eisenhowers only concern; Powers had been flying a plane that wasnt supposed to exist on a mission that wasnt supposed to exist. In need of a cover story, the President turned to NASA.
The U-2 was built on Eisenhowers request as a lightweight high altitude reconnaissance aircraft. Conceived in 1954, it was reminiscent of a glider with its 103 foot wingspan dwarfing its 63 foot long fuselage. This high lift design combined with its extremely low weight (it weighed just 17,000 pounds on its first flight) enabled the U-2 to cruise at over 70,000 feet. But even from this formidable height cameras could could resolve individual missiles at Soviet firing ranges. The lenses were just that good.
Right from the start, the problem for Eisenhower was that he couldnt divulge the U-2s real purpose. When the aircraft began flying reconnaissance missions in 1956, the President had NASAs predecessor organization the National Advisory Committee for Aeronautics lay a cover story. On May 7, the agencys director Hugh Dryden issued a press release saying that the U-2 was an NACA research plane designed to fly high altitude meteorological flight with Air Force support from a base in Watertown, Nevada. A second press release on May 22 gave a similar story to account for U-2s flights overseas.
The weather flights story was reused to account for Powers disappearance. On Thursday May 5, 1960, NASA issued a press release saying a U-2 had gone missing over Turkey during a routine meteorology flight.
One of NASAs U-2 Research Airplanes, in use since 1956 in a continuing program to study gust-meteorological conditions found at high altitude, has been missing since about 9 oclock Sunday morning when its pilot reported he was having oxygen difficulties over the Lake Van, Turkey area. It went on to detail a non-existent mission.
The airplane took off from Incirlik Air Base at 8 a.m. local time on a flight path through Turkish airspace. But an hour into the flight, the pilot reported difficulties with his oxygen equipment. Over his emergency radio frequency he announced that he was heading towards a beacon point near Lake Van. It is believe he probably was on a northeasterly course, but there was no further word. NASA lost contact with the pilot over southern Turkey.
Air searches revealed no evidence of a crash around Lake Van, suggesting that the pilot was still alive. If this was the case, he should not be treated as a war criminal. NASA stressed that all its U-2 pilots are civilians, employed either by the agency or the aircrafts manufacturer Lockheed. These men have no military affiliation save a working relationship with the U.S. Air Force, which facilitated these civilians presence overseas.
The release details the instruments onboard the U-2, basic flight systems and specialized instruments designed to measure things like air turbulence, wind shear, and water vapor in the atmosphere. There were even instruments to measure the presence and effect of cosmic rays at high altitudes. This explained the U-2 cruising height of 55,000 feet.
To support this press release, NASA offered proof. At the agencys Flight Research Center at Edwards Air Force Base, a U-2 was hastily adorned with a yellow NASA tail stripe and a registration number. The aircraft was put on display before the media on May 6.
Of course, none of this was real.Powers wasnt a civilian on a weather flight and NASA didnt have its own U-2s for research flights. The registration number painted on the aircraft was bogus.

NASA's Donated Spy Telescopes May Aid Dark Energy Search
LONG BEACH, Calif. Astronomers are excited by the possibility of using one of two cast-off spy satellite telescopes gifted to NASA to probe for dark energy.
They have already come up with a design that would incorporate the spy telescope into the proposed Wide Field Infrared Survey Telescope (WFIRST), a high-priority NASA mission that would hunt for dark energy, exoplanets and supernovae.
Though a final review and economic analysis won't be released until April, the new design based on the donated scopes would boost WFIRST's abilities significantly, some researchers say. But the concept could also require more power and a bigger launch vehicle, potentially raising the project's roughly $1.5 billion price tag.
More powerful probe
In June, the U.S. National Reconnaissance Office donated to NASA two 2.4-meter telescopes that were part of a failed spy satellite program. The telescopes have roughly twice the collecting surface as earlier designs of WFIRST, which allows for better resolving power. They also have a better field of view than existing telescopes (though smaller than some initial design proposals). [Gallery: Declassified U.S Spy Satellite Photos and Designs]
"The magic of this telescope compared to existing telescopes like the James Webb Telescope or the Hubble Telescope is it has a huge field of view," NASA astrophysicist Neil Gehrels said during a presentation of the new designs here at the 221st meeting of the American Astronomical Society on Jan. 8.
The new proposed design also includes a coronagraph, which can block out starlight to resolve exoplanets and other objects.
Complementary telescope
Another advantage of using the spy telescope is that it may complement existing projects.
For instance, the Euclid project headed by the European Space Agency will scan for dark energy the mysterious force thought to be accelerating the expansion of the universe but using a wider, shallower survey. The proposed WFIRST design could then go in and probe in more detail, researchers said.

To ensure that the future of the US space exploration program keeps its head above water, NASAs Kennedy Space Center has partnered with the private sector to get Orion rolling out the door. By employing outside workers, NASA has provided a means to expedite the Orion spaceship building process from months to just days.
Working with contractors from Lockheed Martin, NASA is working hard at Kennedys Operations and Checkout Building preparing Orion for its first launch (Exploration Flight Test-1 or EFT-1) in 2014. Orion is being designed to ferry American astronauts farther into space than ever before.
The cooperativeness is allowing the Orion team to achieve scheduling milestones much faster than it would have if NASA kept the program as an inside job only.
This new and unique working relationship, in essence having a Lockheed Martin factory within a NASA facility, has allowed us to leverage Lockheeds strength in building spacecraft and the strength of our Kennedy workforce in providing world-class services and facilities, Scott Wilson, manager of production operations for the Orion program, said in a statement.
Wilson said several processing milestones have been achieved in preparation of EFT-1. The team has ensured that the spacecraft will be ready for a 2014 launch, and with the assistance of engineers and technicians from a number of different companies, as well as those working for NASA, has also ensured that issues arising during the on-site assembly and preparation of Orion have been met and diffused.
Other major milestones that lie ahead will be testing the crew module, powering up the vehicle for the first time, completing subsystem installations, assembling the service module and launch abort system, and joining the crew and service modules together.

NASA Solar System Exploration Research Virtual Institute Cooperative Agreement Notice
Solicitation Number: NNH13ZDA006C Posted Date: January 10, 2013 Proposal Due Date: April 10, 2013
The National Aeronautics and Space Administration (NASA) is soliciting the submission of multiinstitutional team-based proposals for research as participating members of the Solar System Exploration Research Virtual Institute (SSERVI), hereafter referred to as "the Institute." The Institute will succeed the current NASA Lunar Science Institute. Proposals must clearly articulate an innovative, broadly based research program addressing basic and applied scientific questions fundamental to understanding the nature of the Moon, Near Earth Asteroids (NEA), the Martian moons Phobos and Deimos, and the near space environments of these target bodies, to enable human exploration of these destinations. Proposals in the areas of astrophysics and heliophysics that are enabled through human and robotic exploration of the Target Bodies are also solicited through this Cooperative Agreement Notice.
The research scope for the CAN is in the fields of lunar, NEA, and Martian moon sciences, with preference given to topics that relate to the joint interests of both planetary science and human exploration. Topics in astrophysics and heliophysics that are enabled through exploration of the Target Bodies are also within the scope of the CAN. The proposed research should address NASA's science and exploration goals (either or both) and should include broadly based investigations of the highest quality that address basic and applied science objectives. The proposed research should be integrated; thus, proposals consisting of tasks addressing multifaceted questions must demonstrate credible, scientific connections among the tasks. Proposals that only address a single question should strive to integrate interdisciplinary expertise and methodologies. It is expected, but not required, that teams bring together broadly based expertise from more than a single institution.
Proposals must also articulate plans to advance the full scope of Institute objectives (http://lunarscience.nasa.gov/overview/). The Institute is supported by a partnership between the NASA Science Mission Directorate (SMD) and the Human Exploration and Operations Mission Directorate (HEOMD). NASA anticipates that approximately seven new teams will be selected through this solicitation.
On or about January 10, 2013, the Cooperative Agreement Notice (CAN) for the Solar System Exploration Research Virtual Institute will be available via the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES) web page at http://nspires.nasaprs.com (go to "Solicitations" and "Open Solicitations").
Participation in this solicitation is open to all categories of organizations. Although international teams are not solicited as part of this call for proposals, U.S. proposers are encouraged to identify projects involving international partners. The intent of this solicitation is to provide funding to U.S. institutions.

NASA's Moon Crash Filmed
A NASA probe recorded a spectacular flyover video of the moon's far side shortly before intentionally slamming into a lunar mountain last month.
NASA's Ebb spacecraft shot the stunning final moon video on Dec. 14, just three days before it and its twin Flow ended their gravity-mapping mission, known as Grail, with a dramatic crash near the moon's north pole.
Ebb was just 6 miles above the lunar surface when it captured the images using its MoonKAM (Moon Knowledge Acquired by Middle school students) camera. The probe was skimming over the far side's northern hemisphere at the time, near an impact crater named Jackson.
Grail scientists pieced together about 2,400 individual frames to make the nearly two-minute video, NASA officials said.
The $496 million Grail mission short for Gravity Recovery and Interior Laboratory launched in September 2011, and Ebb and Flow arrived in lunar orbit about three months later. The washing-machine-size spacecraft spent a year zipping around the moon, detecting the tiny changes in the distance between them caused by lunar mountains, craters and subsurface mass concentrations.
The Grail team used these super-precise measurements to construct an incredibly accurate map of the lunar gravity field the best ever created for any celestial body, researchers said.
But Ebb and Flow couldn't keep flying forever. They were running out of fuel by last month and would have crashed into the moon eventually, so the mission team decided to bring them down in a controlled fashion, far from the Apollo landing sites and other areas of historical importance.
So on Dec. 17, the two probes slammed into a crater rim near the moon's north pole. Shortly after the impact, NASA announced that the crash site would be named after the late Sally Ride, America's first woman in space.
Ride had led Grail's MoonKAM project, which allowed schoolkids around the world to pick out sites for Ebb and Flow to photograph. She died last July at the age of 61 after a battle with pancreatic cancer.

NASA buys $18M inflatable room for international space station
NASA has officially signed a deal to attach an inflatable private module to the International Space Station, space agency officials confirmed Friday, Jan. 11.
Under the new deal, NASA will pay $17.8 million to the Nevada-based private spaceflight firm Bigelow Aerospace for the company's Bigelow Expandable Activity Module (BEAM), which will be affixed to the orbiting lab as a technology demonstration.
"This partnership agreement for the use of expandable habitats represents a step forward in cutting-edge technology that can allow humans to thrive in space safely and affordably, and heralds important progress in U.S. commercial space innovation," NASA deputy chief Lori Garver said in a statement.
Friday's announcement confirms reports that surfaced earlier in the week. Garver and Bigelow founder and president Robert Bigelow will discuss the BEAM program at a media event Jan. 16 at Bigelow Aerospace facilities in North Las Vegas, NASA officials said.
- NASA deputy chief Lori Garver
BEAM is likely to be similar to Bigelow's Genesis 1 and Genesis 2 prototypes, which the company launched to orbit in 2006 and 2007, respectively. Both Genesis modules are 14.4 feet long by 8.3 feet wide, with about 406 cubic feet of pressurized volume. [Photos: Bigelow's Inflatable Space Station Idea]
NASA officials have said that BEAM could be on orbit about two years after getting an official go-ahead. The module will likely be launched by one of the agency's commerical cargo suppliers, California-based SpaceX or Virginia-based Orbital Sciences Corp.
Bigelow's dreams don't stop at the International Space Station. The company wants to launch and link up several of its larger expandable modules to create private space stations, which could be used by a variety of clients.
Tenants could get to orbiting Bigelow habitats in several different ways. The company has set up a partnership with SpaceX for use of its Dragon spacecraft and another one with Boeing, to use the aerospace giant's CST-100 capsule.
Bigelow is also eyeing a possible outpost on the moon, for which the company envisions using its BA-330 modules (so named because they offer 330 cubic meters of usable internal volume). Several BA-330 habitats, along with propulsion tanks and power units, would be joined together in space and then flown down to the lunar surface.

Promises of nanotechnology for Bangladesh
Navid B. Saleh
The Daily Star
Publication Date : 14-01-2013
Since the inception of the new millennium, scientists have embarked on an exciting journey of developing novel materials with unique properties that are revolutionising the world around us. Chemical manipulation at the nano-scale -- that is at a linear scale equivalent to a billionth of a metre -- has allowed to alter, enhance and incorporate physical and chemical material-properties. Such innovations have generated new materials improving the products, devices, and processes of immense commercial and scientific importance; for example, transparent catalysts for touch-screen devices, high-efficiency semiconductors for solar cells, core-shell particles for deliverable and release-controlled drugs, heat-conductive materials for cancer therapy, reactive agents for environmental cleanup, etc. Such promises of nanotechnology emanate from its ability to crosscut disciplinary boundaries and its ability to be applied to any field, which desires improved material properties for better efficiency and performance. Thus, many developing countries, which are otherwise not heavily involved in technology development, are entering a phase of technological competitiveness using this interdisciplinary field of nano-scale science. Leaving Bangladesh, a leading nation in the "Next 11", out of this race seems to be unwise. This article will introduce fundamental and applied aspects of nanotechnology and will discuss the promises of this technology for Bangladesh.
Nanotechnology is founded on material manipulation at the nano-scale, where at least one dimension of the material is sized between 1 and 100 nanometres. Its scale aspect can be facilitated by comparing between the sizes of the earth, a soccer ball and a nanoparticle; that is, the ratio of the earth's diameter and the diameter of a soccer ball, roughly equals the ratio of the diameters of a soccer ball and a nanoparticle. In defining a nanomaterial, it is imperative to identify that the material of concern has uniquely different properties at the nano-scale compared to its larger scalar forms. Since nano-scale materials are sub-microscopic, that is, cannot be observed even with high powered optical microscope, the development of this field required advances in electron microscopy; which was introduced in 1981 via introduction of scanning tunneling microscopy (STM).Though the fundamental concepts of nanotechnology was discussed by Nobel laureate Richard Feynman in 1950s, the first nanomaterial development and identification occurred in mid 1980s through the all-carbon fullerene's discovery by Nobel laureates Harry Kroto, Richard Smalley, and Robert Curl. Later on, tubular fullerenes or carbon nanotubes' incidental discovery by Sumio Iijima in 1991 advanced the field of nanotechnology a bit further. Though the initial development of nanomaterials started with carbon-only structures, scientists have utilised many of the metals and other non-metals as core elements to engineer novel nanomaterials. The singular nanomaterial synthesis and characterisation has flourished since the latter half of the 1990's decade. These materials are used in various applications till today. However, the current focus in this field has shifted towards conjugation of multiple nanomaterials to form hierarchical structures with the intent to extract multi-functionality from a single engineered material. The field of nanoscience and nanotechnology has passed its infancy and is now gaining pace aided by the global economic turnaround. It is high time to ride this 'technological wave' before it is too late for us to join in as a competitive force in research, development, or application of nanotechnology.
It is probably well perceived by now that nanomaterials possess sub-microscopic size that gives added material-advantage. But, what are these advantages and why are these manifested at this scale? Here, the two most profound nano-scale effects are discussed in brief. As a material is sized down, the effective surface area of the material expands, providing more room to perform novel physics, chemistry, and biology. Consider a simple example: a loaf of bread has a total of six sides; if the loaf is sliced in half, the total volume of the bread remains the same, however, number of sides increases by two (along the length of the cut). If the loaf is sliced in four equal squares, eight new surfaces will emerge from the same volume of material. This is how, sizing down a material continues to increase exposed surfaces and allows scientists to incorporate more functional entities on the newly exposed planes. The second manifestation is known as "quantum effects". Gold nanomaterials demonstrate such unique effects at this scale: gold is commonly identified with shiny yellow colour at macroscopic level; however, at the nano-scale the colour of gold changes to red or purple, due to quantum confinement. The optical properties, for example, colour of a material originates from electronic vibration of molecules or collective phonons or lattice modes. The vibrational frequency of the electrons is identified with either a visible colour or remains undetected as invisible infrared or ultraviolet radiation. At macro-scale, electron movement on or through the gold lattices encounters more freedom yielding the yellow coloured appearance of the material; which is compromised at the nano-scale due to quantum confinement issues. The change in electron vibration is reflected via change in colour of the gold nanoparticles that are effectively utilised in medical imaging. Similarly, quantum effects alterreactive, electromagnetic, and biological properties of a material and can be effectively utilised for various applications.
Unique material attributes mentioned earlier are utilised in many applications that include: electronics, energy applications, sensors, drug delivery, therapeutics, etc. Can Bangladesh take advantage of this novel technology? The immediate reaction will likely be a loud and resounding "NO". General public perception in our country for advanced technologies is that these are too high-tech for a developing country like Bangladesh.
We cannot afford to spend time and resources on such endeavours when basic needs for many are not met. In presenting this argument we forget that our economy has traditionally relied on agriculture and recently on garment sector to drive the economic engine. We merely have any competitive advantage in industrial sector other than cheap labour. Other countries such as India, Sri Lanka, Vietnam and the Philippines are already trumping us on this argument. Many of the aforementioned countries realise that cheap labour advantage is going to be short-lived and have already begun a concerted and focused effort in nano-technological development. Why and how is that possible? It may appear that nanotechnology will require expensive equipment and ultra-clean facilities to pursue research and development. It is mostly true for nano-electronic sector and probably that is why none of these countries have chosen nano-electronics as their focus area. Many nanomaterials can easily be synthesised via wet-chemical processes which are simple to perform and can be pursued anywhere. Using such techniques and following the path showed by countries like India or the Philippines, we can pursue nano-scale research and development with a focused effort: may be on agricultural, pharmaceuticals, garment industry, or cement products. The research focus can utilise wet-chemistry, where the identification and characterisation of nanomaterials can be done using already existing imaging facilities at the Dhaka centre of our Atomic Energy Commission. The industrial wing on the other hand can pursue collaboration, where international patents can be used to manufacture products related to the focus industries. One of the first efforts, however, should be establishing academic training programmes that will develop a trained professional class, serving as a competitive advantage to attract international business.
This article has hopefully introduced fundamentals of nanotechnology and demonstrated its advantages. It is imperative that Bangladesh should begin to transform itself from a mere consumer to a product/device manufacturer; nanotechnology can provide this kick-start. The efforts should be focused and well planned and should utilise the existing infrastructure and strength that Bangladesh possesses. I believe that Bangladesh can curve a strong scientific mark in the international arena using nanotechnology and its brilliant younger generation as essential vehicles.

Krishna P. Singh Center for Nanotechnology construction nearly over
Jen Rizzi | DP
The Krishna P. Center for Nanotechnology is on its way to completion this November. It will house researchers from the School of Engineering in nanotechnology, as well as those working on nanoscience-related fields like chemistry, biology, physics and even medicine.
The new gateway to Penns campus on Walnut Street is intricate, both in its design and the technology within.
The construction of the Krishna P. Singh Center for Nanotechnology, which broke ground in February 2011, is nearing its completion. Currently in its punch list phase, the University will start moving in equipment to the building on 33rd and Walnut streets in February. The grand opening for the $88 million state-of-the-art facility is scheduled for Nov. 7.
The building, which features a modern-looking exterior, was designed by New York-based architects Marion Weiss and Michael Manfredi.
The science in here could be very happy in a windowless, anonymous building but from the very beginning, that has not been the aspiration of the University, said University Architect David Hollenberg.
This summer, the building will really be coming to life from Walnut Street, Christopher Kern, director of design and construction at Facilities and Real Estate Services, said. It has a really nice presence, and its a really nice signature piece for coming into campus.
The Singh Centers complex design, which features a second-level overhang, as well as the specifications that research in nanotechnology demands, has made its construction very difficult.
This was especially complex because its not like a building weve ever done before its not a classroom building, its not a conventional building, the science in it isnt conventional and the equipment isnt conventional, Hollenberg said. It required a very high degree of coordination with the people who are going to use it.
The University plans to take occupancy in February, when it will start transporting microscopes from the adjacent Edison building into the basement of the new nanotechnology center.

Nanotechnology economic benefits extolled
Richard Blaikie.
That is the message from University of Otago research and enterprise deputy vice-chancellor Richard Blaikie, who made the comments after a public lecture in Dunedin on ''Seeing Small'', where he spoke about the history of nanotechnology and optics and its current applications.
Nanotechnology, which involves the engineering of functional systems at the molecular scale, could add billions of dollars to the New Zealand economy, he said.
The Government was already taking positive steps to ensure there was growth in the sector, he said. This could be seen with the creation of Callaghan Innovation, which would aim to get the country's most innovative ideas out of the lab and into the marketplace more quickly once it became operational next month.
It was also important the number of companies involved in nanotechnology increased, which would give ''people the belief we can do this stuff here as well'', he said.
If the sector grew, New Zealand would be more likely to attract big players, such as computer chip manufacture Intel, to its shores. However, attracting the big companies was also dependent on other factors, including tax rates, he said.
At the public lecture, which was part of Otago University's latest annual ''Hands-on-Science'' school, Prof Blaikie spoke about the importance of nanotechnology, which had applications in everything ''from airbags to iPhones''.
He also spoke about the related field of optics and the quest to build microscopes that could see ''smaller and smaller'' things.
This goal was related to the massive industry around building smaller computer chips, with powerful lenses used to print semiconductors on silicon.
Prof Blaikie said the rapid progress of this industry had been amazing.
