The McMath-Pierce Solar Telescope

The McMath-Pierce Solar Telescope at Kitt Peak National Observatory in Arizona, USA, looks like a monumental piece of modern art. A great white, inverted-V like concrete structure rises 110 feet up towards the sky from which a shaft slants two hundred feet to the ground. At the top of the tower is a 3-mirror heliostat which collects the sun’s light and directs it down the diagonal tunnel which continues for another three hundred feet into the mountain, forming an underground tunnel. At the base of the tunnel is a 34-inch parabolic mirror that captures the image of the sun. Built in 1962, it is the world's largest solar instrument as well as the largest unobstructed aperture optical telescope, with a diameter of 1.6 meters. Although designed to study the sun, it is so sensitive that it can even observe bright stars in the night.

In addition to the primary mirror, there are also an East- and West-auxiliary telescope which are completely independent of the main telescope and are equipped with their own heliostats and mirrors. Instruments inside the underground facility include a dual grating spectrograph capable of extended wavelength coverage (0.3-12 microns), a 1-meter Fourier Transform Spectrometer for both solar and laboratory analysis, a high-dispersion stellar spectrometer, and bunch of other detectors.
The telescope’s observation room and instruments are located underground to avoid the temperature fluctuations that occur aboveground. The heliostat that is exposed at the top of the tower is protected by a steel jacket and a cooling system.
The McMath-Pierce Telescope is used to study the structure of sunspots, as well as sunspot spectra. Important discoveries made with this telescope include the presence of water and isotopic helium in the sun, solar emission lines at 12 microns, first measurement of Kilogauss magnetic fields outside sunspots and the very weak intra-network fields, first high resolution images at 1.6 and 10 microns, as well as detection of a natural maser in the Martian atmosphere.
The telescope is named after astronomers Robert McMath and Keith Pierce. At its dedication in 1962, Dr. Waterman read a letter from President Kennedy which began:
“The great new solar telescope at the Kitt Peak National Observatory in Arizona is a source of pride to the nation. The largest instrument for solar research in the world, it presents American astronomers with a unique tool for investigating the nearest of the stars, our sun. This project is of exceptional interest to all our citizens...”

Scientists catch new 'baby' planet in the act of formation

Scientists scanning the galaxy have spotted big planets and small ones, rocky planets and gassy planets, freezing planets and hellishly hot ones. Now astronomers have strong new evidence of yet another kind of world: a baby planet in the very act of formation.

It's the first time researchers have definitively identified a juvenile planet. This one, named LkCa 15 b, has been caught gobbling dust and super-heated gas, a meal that will help it bulk up. Pictures of the new baby show that, just like many human newborns, it's reddish in color.

"The ultimate question we all want to answer is, how common are Earth-like planets and how are they formed?" said Stanford University astronomer Kate Follette, an author of a new study in this week's Nature describing the planet. "This is a step along the way."

LkCa 15 b and its star lie about 470 light-years from our own solar system in the constellation Taurus. Previous research suggested there might be an embryonic world in this particular spot in the galaxy. So University of Arizona astronomer Stephanie Sallum and her colleagues trained some of the world's biggest and most sophisticated telescopes on this potential planetary nursery.

Using a telescope in the high desert of Chile, the scientists found super-heated hydrogen gas – a "smoking gun" for the presence of a young planet, said Rice University astronomer Andrea Isella, who was not involved with the research. A telescope on an Arizona mountaintop revealed traces of one or two additional planets, also young, orbiting the same star as LkCa 15 b.

Past research by University of Texas, Austin astronomer Adam Kraus suggested there might be a baby planet in this very place, and Kraus, who was not involved with this week's study, said the new findings "remove any doubt" about the presence of one youngster – the planet the study calls LkCa 15 b. He thinks a three-planet system is plausible, but he'd like to see more data confirming three planets rather than just one. Sallum said other evidence points to multiple planets as the most likely explanation.

Whatever the tally of planets-in-the-making, there's solid evidence for LkCa 15 b, which is 2 million years old at most – a mere toddler compared with our solar system. Our solar system is aged 4.6 billion years old – "boring middle age," Kraus joked. With the help of fresh young worlds like LkCa 15 b, scientists will be that much closer to understanding how planets are born and how they grow.

Astronomers Gain First Insight into Planet Formation

For the first time, a team of astronomers and astrophysics have witnessed the planet formation of two or three small planets orbiting around sun-like star at a distance of about 430 light-years away from Earth. Witnessing the planet formation will help scientists to know how planets look like in their formative years. The findings of the study have been published Wednesday in the journal Nature.

Till now, about 1,900 planets have been found orbiting small starts in the outer space and the mature planets have been discovered only when they pass in front of the stars they orbit causing the light to dim. The team of astronomers used their powerful telescope in Arizona towards the young star, LkCa 15, and the relatively empty space around them, the disk cavity, to gain clear insight about their formation. Astronomers have taken the first images of the planet still in formation around a star LkCa 15, which is 2 million year old.

For the first time, scientists have also found the chemical footprints of superheated hydrogen gas streaming from the dust disk onto the planet. Stephanie Sallum, a University of Arizona astronomy graduate student, said “This young system provides the first opportunity to study planet formation and disk–planet interactions directly”. Zhaohuan Zhu, Princeton University astrophysicist, said that the new study will help scientists modify their previous theories on planet formation.

Russia and Iran Space Cooperation

Russian Deputy Prime Minister Dmitry Rogozin in charge of the
defense and space industry is currently on a visit to Tehran.

Iran and Russia have reached agreement on expanding cooperation in space research, Russian Deputy Prime Minister Dmitry Rogozin told upon the end of talks with the Iranian Vice President in charge of science and technologies, Sorena Sattari.

“Russia and Iran have fair prospects for cooperation in the studies of outer space,” he said. “For instance, some of their programs envision cooperation in the field of remote sounding of the Earth’s crust,” he said.

“Many people using cell phones are unaware of the fact the Russian GLONASS system is used alongside others in the positioning process,” Rogozin said. “More than 2.5 billion phones and other gadgets receive the signals from our system.”

“Iran is a big country with lengthy borders and, quite naturally, the Iranians find it important to know and to see from space what is happening on their territory and in the areas adjoining it, while our satellite system will enable them to do this,” Rogozin said.

“Russia is the world leader in terms of satellite launch services at present,” he said. “We’ve done test launches of a very powerful launch vehicle, the Angara, which may become the main type of rockets taking payloads into orbit. But we don’t plan to stop at that.”

“The launching of other countries’ satellites makes up only 4% to 5% of the entire market of space services that Russia could offer worldwide,” Rogozin said. “And recall we have the areas of cooperation with Iran as promising as satellite-assisted navigation and mapping. Russia and Iran have a good groundwork for acting together in this aspect.”

In the course of Rogozin’s visit to Tehran, the Russian-Iranian high-level commission co-chaired by Rogozin and Sattari had its third session. It was set up earlier this year when the Moscow International Aerospace Show MAKS’2015 was underway.

The commission is called upon to promote and coordinate Russian-Iranian cooperation in research and technologies having priority for the two countries’ economies, the social sector, sciences, and innovations.

‘Govt not biased towards funding of space science’

The budgets for space missions are not very high and scientists from other branches must not make a hue and cry out of it, Chairman of Indian Space Research Organisation (ISRO) AS Kiran Kumar has said.

Kumar rubbished the allegations made by senior scientist and Bharat Ratna awardee CNR Rao that the government is biased towards funding of space and nuclear sciences and ignores basic sciences.

“It would be wrong to say that government funding for developing space technology is higher. Even today, the yearly budget allotted is around Rs 4,000 crore, which is not a substantial amount, considering the number and scale of missions undertaken,” Kiran Kumar told Sakal Times.

Rao, who was in Pune for the annual meeting of the Indian Academy of Sciences earlier this month, had said the government must urgently look into funding  researchers studying basic sciences.

“The future of these researchers will be bleak unless there is government backing. They will have to stop their research as they will be worrying if their project will survive the following year or not,” Rao had said during the meeting.

At present, about 0.8 - 0.9 per cent of the GDP is alloted for scientific research. Further, nearly 25 - 30 per cent budget was slashed by the NDA government, leaving many projects in the lurch.

However, the ISRO chief claimed that the space agency was making bigger contributions than other scientific institutions.

“Our work is open for public review and there has been bigger contributions for society as a whole,” added Kiran Kumar.

Director General of Science and Technology Park, Rajendra Jagdale, however, said that he was against complete dependency on the Centre for funding and some onus of supporting science research also lies with the State government.

“It is not necessary that one must completely depend upon the Centre for funds for doing research. Even state governments must chip in and share the financial burden,” Jagdale said.

He also voiced his concerns about the gap between the Central government’s vision towards making the country an innovation hub and the financial allocation. He lamented that the government was indulging more in rhetorics and less action was visible.

“Make in India, NITI Ayog and several other rhetoric announcements made by Modi have not reflected in the process of boosting education and research in the country,” he said.

Manned mission not priority: ISRO chief - Bhubaneshwar

The much-publicized manned space mission is not a priority for Indian Space Research Organization (ISRO), chairman A S Kiran Kumar said here on Saturday.

"Our priority is to build capacity for new (satellite) launches," Kumar said while interacting with mediapersons on the sidelines of KIIT University convocation.

The ISRO chief, who is also secretary, department of space, said the agency is planning to increase the frequency of new satellite launches to 10 to 12 per year against present one to six. From December to March, there would be at least one launch every month, he said.

Kumar said it would be a difficult task to give any timeline for human spaceflight programme. But it is very much part of the ISRO's future agenda. The agency is in the stage of 'critical technology development' for the human spaceflight mission, he said.

"The crew module re-entry exercise was done last year. Activities such as development of environment control system, maintenance of oxygen and carbon dioxide and contingencies such as extricating the astronauts in case such a need arises are on. These are critical technology requirement activities in the research and development, he said.

The ISRO chairman said the future of the manned programme would depend on government clearance. "Lots of investment is required for it," he said.

Kumar said space tourism as a concept is catching up fast globally. Just like the sequence of development in shipping and aircraft industries, space tourism and space adventure would be natural development process in the future space technology. One of the key ISRO activities would be to help industries build up the capacity for space tourism, he said.

NASA Hiring New Astronauts For The First Time In Four Years

If one of your dreams is to become an astronaut, you might be in luck - NASA is accepting applications for future astronauts to join the 47-man astronaut team between December 2015 and February 2016.

NASA says the nearing return of astronauts to American soil, as well as the possibility of a mission voyage to the Red Planet has necessitated the call for applications, writes Christian Science Monitor. The space agency has promised that the chosen astronauts will have the opportunity to be part of an "unprecedented transition to commercial spacecraft for crew and cargo transport to the space station," according to a press release.

"This next group of American space explorers will inspire the Mars generation to reach for new heights, and help us realize the goal of putting boot prints on the Red Planet," said NASA Administrator Charles Bolden in a statement. "Those selected for this service will fly on U.S. made spacecraft from American soil, advance critical science and research aboard the International Space Station, and help push the boundaries of technology in the proving ground of deep space."

To be considered for one of the positions, applicants must have a bachelor's degree in engineering, biological science, physical science, or mathematics. The space agency will consider advanced degrees over those without.


Aside from the academic requirements prescribed by the space agency, candidates should have at least three years of "related, progressively responsible, professional experience" or at least 1,000 hours of "pilot-in-command time in jet aircraft," which, according to Space.com, may indicate that NASA is hoping to encourage military candidates.

The physical requirements are also an important part of the application, as astronauts must endure a lot of physical strain during missions due to the effects of being in an environment which does not follow the laws of gravity, which would likely cause health issues for those unprepared to cope in a space environment for an extended period of time.

However, physical height is one requirement that may immediately eliminate some candidates from the pool. NASA has specified that in order to qualify, commander and pilot candidates must be between 62 and 75 inches tall.

Successful candidates will undergo two years of training, which includes military survival water training, scuba diving qualification, high and low atmospheric pressure testing, training in Russian language, and test flights aboard a jetliner that has been modified to simulate weightlessness in space, colloquially known as the "vomit comet". All of these tasks must be successfully completed prior to being considered an official astronaut.

Observatory Builds a Ramp to the Cosmos

On a Friday night in October, Jesse Shanahan, a graduate student in the Astronomy Department, stood behind an inflatable planetarium. The silver, blown-up stellar theatre, they explained (Shanahan uses gender-neutral pronouns), was part of Kids’ Night, a public outreach program aimed at children. Later, kids would go inside to view projections of the stars and constellations in the night sky.

Shanahan founded Kids’ Night earlier this year. When we spoke, though, they expressed a major concern: the location. Shanahan advocates for disability rights within the American Astronomical Society (AAS), the largest astronomical organization within the United States. As with other events the Astronomy Department hosts, Kids’ Night is housed in the Van Vleck Observatory, a building that has no wheelchair-accessible entrances.

“I worked primarily with kids with disabilities and cognitive impairments and stuff [with an outside organization], especially, and they would not be able to come to an event that I put on here,” Shanahan said. “That really bothers me.”

Currently, the Astronomy Department—working with Physical Plant and the Office of Student Affairs, of which Disability Resources is a part—is in the process of addressing Shanahan’s concerns. Physical Plant is currently working with an outside architect to draw up plans to build a ramp in the architectural style of the 99-year-old building, making the observatory wheelchair-accessible on the first floor.

These plans would still not make accessible the dome for the 20-inch telescope, however. In order to address this concern, a monitor will be installed inside the library of the observatory, connected to a camera that will be attached to the 20-inch telescope.

According to Roy Kilgard, Support Astronomer and Research Associate Professor of Astronomy, initial plans to address accessibility issues at Van Vleck Observatory included the possibility of making the 20-inch telescope dome wheelchair accessible, but were abandoned due to logistical concerns.

“There’s a lot of challenges involved in [making the dome wheelchair-accessible]; it’s unclear that it ever would’ve worked for any sum of money and it would’ve been a massive renovation to the building,” Kilgard said. “So that was ruled out.”

Kilgard said he came up with the idea of the camera as a more affordable and feasible solution to the problem of making the dome accessible. The camera and monitor, he later wrote in an email to The Argus, will be installed by the beginning of spring semester.

Efforts to make the Van Vleck Observatory more accessible, administrative officials said, are part of a larger plan for the University to address concerns regarding accessibility on campus and meeting the requirements of the Americans with Disabilities Act (ADA), a 1990 law that requires that people with disabilities are offered reasonable accommodations from employers. As with the rest of the University, they said, the age of the observatory and the hilly terrain surrounding it make these concerns especially hard to address.

“There’s a constant conversation on campus around accessibility,” Laura Patey, Associate Dean of Student Academic Resources, said. “I mean, we recognize that [with] topography and the age of some of our buildings, accessibility is a challenge on this campus. And we’re always wanting to improve that.”

According to a document provided by Roseann Sillasen, Associate Director and Project Manager of Facilities, the University has spent through Physical Plant $2.23 million since 2003 on campus-wide accessibility projects. Those initiatives range from making pathways more accessible to building restrooms designed for wheelchair users to putting ADA-compliant phones, which are required to be hearing-aid compatible, into elevators.

The University has limited funds set aside for ADA-related projects; The Facilities Planning Committee—an executive committee of the University—sets priorities about which parts of campus are first renovated for accessibility concerns, Sillasen said. According to University President Michael Roth, a large factor in setting these priorities lies in how much activity different buildings experience.

“Those buildings that have either the most public or student activity we want to make sure are the most accessible first, and then we hope that every building meets ADA requirements and goes beyond them when we can,” Roth said.

Until this summer, the Van Vleck Observatory had not received money from the University to address accessibility concerns. The reason for this, Sillasen suggested, is because Physical Plant makes assessments about which ADA-related projects it does based on student and faculty feedback—and, until somewhat recently, it had received none.

“No student has asked me about Van Vleck,” Sillasen said. “So I have had a request from the chair of the department. And at that time, I had provided some very broad scope schematics looking at topography and now we have an architect who’s providing some schematic designs from us.”

Sillasen said that the University uses feedback from people in the Wesleyan community, in large part, as a way of identifying which parts of campus have issues with accessibility.

“I’m out there on campus a lot, but I don’t have the opportunity to be everywhere on campus,” Sillasen said.

In order to address what some of these concerns are, Disability Resources added an ADA/Campus Access Barriers Report Form, through which students, faculty, staff, and visitors can report accessibility concerns, Patey said.

“This would provide an opportunity for anyone in the community to help us identify barriers that might exist for an individual,” Patey said.

But at places like the Van Vleck Observatory, where faculty and administrative officials have long known about lack of access for wheelchair users and other people with disabilities, waiting for students or faculty to issue complaints concerns Shanahan.

“I think a lot of people have good intentions to change things,” Shanahan said. “But I hate that we have to wait for somebody to be in need before we make changes.”

Even with an understanding of areas on campus where accessibility issues need to be addressed, renovations to make buildings accessible take time to implement. In an email sent to The Argus, Patey pointed to several other academic buildings on campus that are not accessible, including the Anthropology building on 287 High Street and buildings in the Center for the Arts.

Physical Plant, Kilgard said, has been looking at adding a ramp to the Van Vleck Observatory for a number of years.

“They’ve just been putting it into the long-term planning for construction that happens to the University,” Kilgard said. “Those things take a very long time to filter through. It’s not as fast as you would like it to be.”

And the process is far from over. This June, the Astronomy Department will be hosting a centennial celebration in honor of the hundredth anniversary of the Van Vleck Observatory. Although faculty within the Astronomy Department had hoped to see a ramp installed by then—along with other features, like the building of an accessible restroom and doorways and entryways designed for wheelchairs—such changes are unlikely to occur by then.

“It’s going to take years, is my guess,” Moran said.

On the day of the centennial, Kilgard said, Physical Plant will install a temporary ramp to the Van Vleck Observatory. In part, this is intended to allow visitors access to the building. It will also be installed, Shanahan said, because the J. Monroe Van Vleck Professor of Astronomy, Emeritus, Arthur Upgren, plans to visit the Observatory and is a wheelchair user.

“He can’t get into his own department, where he worked here for decades,” Shanahan said. “And so, we have our centennial celebration next semester and he can’t get into the building.”

Because of the ramp, Upgren should be able to view the inside of the building. Still, faculty in the Astronomy Department wait to see a more permanent fixture installed—one that would allow Shanahan’s students to visit Kids’ Night on any Friday night they choose.

Astronomy for People with Disabilities ...

Have you ever wondered what would the world look like if you suddenly lost one of your senses? Or if you could not walk or even move?

I think much of what now seems to me easy would become difficult, challenging all the time: the world would even turn into quite a menacing place. And yet, some people overcome those difficulties day after day, bravely, showing to the rest of us that is not senses what matter, but ingenuity can take you far, far away… as far away as to make you reach for the stars, why not?


That is the idea behind the project of astronomy for people with disabilities that we started some years ago at the Astronomical Observatory of the University of Valencia in Spain. One of our main goals as an institution is the dissemination of astronomy. Many other do that, luckily. But then, we started to wonder how people with different disabilities would approach astronomy, using different abilities to those that we are used to employing all the time.


We started working with groups of cognitively disabled. For us it was literally like discovering a new world. We talked a lot with their caretakers to learn about them, what did they enjoy best, what to avoid, and then we were ready for the grand opening. We were a bit worried about the event. After all, we are located in a very formal building, surrounded by 'serious'  scientists trying to unveil the secrets of the Universe. How would it be to have our special visitors with us?


The visit went extremely well, with the invaluable help of the caretakers, and at the end we were very impressed with them. They were extremely keen on listening to explanations and watching the images we had prepared. They asked questions, difficult questions. They enjoyed the workshop by building cardboard sundials and their favorite constellation with luminescent stars. Most of them needed help when cutting the cardboard, or drawing the constellation figure. The beautiful thing was how they worked together, helping each other as much as they could.


At the end of the activity they effusively gave us thanks for it, but I think it was us who learnt much more in that day about overcoming difficulties, collaborating, and sharing.


After that experience, we started to develop more activities, reaching for other disabilities. The Universe is there for everybody's enjoyment, so we set up to make as many people as possible to enjoy it. After all, that is one of the goals of our Observatory.


So far we have created a few tools, that are free for everyone to use. You can find them listed here (AWB link), among many others made by astronomy communicators with much broader experience and knowledge than ours.


But the most important thing of this work is not the tools we have or will create, but to inspire other people to do the same. Use your ingenuity to help everybody reach for the stars. We have developed these ones just to make the road a bit easier to those who are new to the field, there is so much we can do!!


If you happen to be an astronomy communicator, teacher, an amateur, or even a professional astronomer involved in astronomy dissemination, how about planning an astronomical event for the school of blind children you have around the corner? Or for the cognitive disabled daycare centre? Once you start you will not be able to stop.

India’s SBAS to roll out soon

India’s GPS-Aided Geo Augmented Navigation (Gagan) system, jointly developed by Airports Authority of India (AAI), the Indian Space Research Organization and Raytheon, has been awarded certification for in Required Navigation Performance (RNP) 0.1 operations. Achieved with the help of quasi-U.S. government non-profit MITRE Corporation, the certification makes it the world’s fourth SBAS system certified for operational use.


The first test flight using the system will fly an approach in mid-2014 from Ahmedabad in the western state of Gujarat. The aircraft is likely to be an AAI-owned Beechcraft aircraft, according to S.V Satish, general manager (ATM-Gagan), AAI. Raytheon has built 15 ground reference stations for the Gagan System, which will provide satellite-based navigation for civil aviation over Indian airspace and adjoining areas in South and Southeast Asia.


The Gagan system was installed to advance safety and improve efficiency of airlines operating in Indian skies. Aircraft equipped with satellite-based augmentation system (SBAS) receivers may utilize Gagan signals in Indian airspace for en route navigation and non-precision approaches without vertical guidance, enabling them to follow more efficient flight paths through congested airspace, noise sensitive areas and difficult terrain.


“The enhanced navigation capability available through Gagan improves air travel for all parties–airlines, passengers and air traffic authorities,” said Brian Hickey, director, Raytheon Navigation and Landing Systems. “In addition to enhancing air traffic safety, the system will result in increased efficiencies and lower costs for Indian aviation.”


The reference stations have been strategically placed in India to optimize signal availability, with uplink stations, master control stations, a communication network and associated software all integrated with Geostationary Earth Orbit satellites transmitting GPS corrections in C-Band and L-Band.


Gagan provides coverage for the entire Indian Flight Information Region via broadcast signals from the Indian-built GSAT 8 and GSAT 10 satellites.

Bhuvan Upgraded: Mapping Tool, 2.5D City Models, Better High-Res Imagery & Others

Indian Space Research Organization’s National Remote Sensing Centre (NRSC) has informed that it recently released upgraded its Google-Earth like satellite mapping tool Bhuvan, adding several new features, datasets and services. These include -

- Bhuvan Mapper: NRSC has released a web-based mapper to allow users to add places of interest across various categories along with a description to the available maps or update the existing maps with new information on a place.

It has also released an Android app which allows users to upload map data from their neighbourhood to Bhuvan. Similar to Bhuvan’s Android app which was released last August, Bhuvan Mapper is also not available on Play Store and one can download the app from the Bhuvan website.

We wonder why is NRSC providing direct links to its Android app on its website, rather than publishing them on Google Play Store, since we feel they are essentially limiting the discoverability of the app through this approach. This might also raise security concerns among users, since people are usually wary of installing third party apps.

- 2.5D City Models: Bhuvan’s 2D viewer has now been updated with 2.5 D models of buildings, Infrastructure and recreational areas for 136 towns across India.

- High Resolution Imagery: It has added improved high resolution imagery with spatial resolution of one meter for 55 cities and towns from the mapping satellite Cartosat-2 besides the existing imagery from Cartosat-1 of spatial resolution of 2.5 meters.

- Bhuvan Collaborative Portal: NRSC’s Bhuvan Collaborative portal now allows users to share, access and upload pests and disease related information in an almost real-time basis. The organization says this portal will serve as a visualization tool for spatial representation of pest and disease incidence reports.

- Disaster Services: NRSC has published a flood hazard map for Odisha, which has been prepared from the information on flooded areas in Odisha during various floods from 2001-2013.

- Support for International Disaster Programs: NRSC is now extending satellite data support through various International Disaster programs like International Charter Space and Major Disasters for International Disaster events; Sentinel Asia Framework & United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER), United Nations Economic and Social Survey of Asia and the Pacific 2013 (UNESCAP).

- Thematic Services: New datasets have been added to Bhuvan’s Thematic services which allows users to select, browse and query the thematic datasets and integrate them into their systems as OGC (Open Geospatial Consortium) Web Services. The new datasets added are LULC (Land Use Land Cover) 50K: 2011-12 covering 12 states, LULC 10K covering 62 districts, erosion, salt affected and water logged area, water bodies and urban sprawl.

- Open Data Archive: The open data archive is extending its services through global coverage products GAC-NDVI and through new products under Terrestrial sciences (Water Fraction) and Ocean Sciences (Tropical Cyclone Heat Potential, Oceanic Heat Content, Wind Products). NRSC also mentioned that it has integrated the latest 2011 LISS III Datasets and improved CartoDEM data with new version data.

- OSCAT: The Oscat 3D visualization viewer now supports Opensource 3D, allowing users to visualize global data from a Oceansat scatterometer without a plugin. It has also added time series visualization in the viewer, allowing users to view datasets from Feb, May, Aug and Oct 2012.

Decatur twins win award from governor

Spend a couple of minutes with paternal twins Tyler and Trevor Parrish and you forget both are in wheelchairs.

Tyler and Trevor Parrish are the 2013 Students of the Year as named by the Alabama Governors Committee on Employment of People With Disabilities. They earned the honor through their work with NASA in the HUNCH program. This is the triple axis motion sensor the brothers created.





Tyler Parrish, right, and twin brother Trevor Parrish are the 2013 Students of the Year as named by the Alabama Governors Committee on Employment of People With Disabilities. They earned the honor through their work with NASA in the HUNCH program. Tyler and Trevor show the device they created, a motion sensor that detects movement along three axis. The brothers were photographed in their home in Decatur, Ala., Dec. 16, 2013.


*******************************************************************************

They don't refer to their muscular dystrophy as a disability, and the wheelchairs that have become their legs are just "the hand we have been dealt," Trevor said.

Pointing to his brain, Tyler said: "Nothing is wrong with this."

The 2013 graduates of Austin High School created a mock-up for the space station and earned the pair the state's Disability Students of the Year award. Gov. Robert Bentley honored the brothers, 19, during a ceremony in Montgomery last week.

The Alabama Governor's Committee on Employment of People with Disabilities has recognized students with disabilities since 1947. The committee is a branch of the Department of Rehabilitation Services, and its primary goals are to educate the public about the benefits of hiring people with disabilities and to promote independence for people with disabilities.

"It came as a surprise and I'm so proud of them," the twins' mother, Rhonda Parrish, said of the award.

The part the twins designed and milled at Austin High is a sensor they said can track movement on the space station. It took Tyler and Trevor three months to conceive and complete the project while they were students in the engineering program.

Family friend and engineer Robert Leke nominated the part for a regional award, which it won. The family thought that was the last recognition it would earn until the governor's office called.

"I was excited," Rhonda Parrish said. "It's just an honor to be recognized by the governor's office."

The road from St. Louis, Mo., where the twins were born, to Montgomery, where they received the award from Bentley, hasn't always been a smooth ride.

They moved to Decatur 15 years ago when their father, Mark, was transferred by Boeing.

Rhonda said the twins showed no sign of muscular dystrophy when they enrolled in the school system. Tyler, the oldest by a minute, was in third grade when he began using a wheelchair regularly. Two years later, MD stripped Trevor of his ability to walk.

They didn't complain then, and they still do not today.

"This does not bother me because I have found my purpose," Tyler said. "I'm here to be an encouragement to others. God has assured me, and I see this as a blessing."

Trevor shared his sentiment.

Muscular dystrophy is a genetic disorder that weakens the muscles that help the body move, according to the Mayo Clinic. Sufferers have incorrect or missing information in their genes, preventing them from making proteins needed for healthy muscles.

Despite the disease, Tyler and Trevor are not letting go of their dream of following in their father's footsteps.

Mark Parrish works at AAR SUMMA Technology in Huntsville as a computer numerical control programmer. He writes programs that mill parts for aircraft, they said.

The twins said they are looking for a company that might let them work from home or under the guidance of another programmer, preferably their father.

"We want to contribute and not have society think we are a burden," Tyler said.

IIT-Kharagpur on Nasa radar

Expertise in radar technology and its successful association with the Indian Space Research Organization (Isro) over the years may soon make the Indian Institute of Technology, Kharagpur, eligible for a partnership with the National Aeronautics and Space Administration (Nasa) for a collaborative research. The presence of two scientists from the premier space research agency in Kharagpur on Monday fanned speculations that IIT-Kharagpur has evolved as the front-runner for the coveted tie-up.

After the success of Chandrayaan, Mangalayaan and the four-year partnership for an oceanic wind measuring radar - Scatterometer - the next most talked about futuristic collaborative project would be the NI-SAR, or the Nasa-Isro radar mission. The radar, which is yet to receive final clearance from the respective governments, is one of the most discussed scientific projects in the country at present, specially because of the precision with which it promises to pre-empt natural calamities.

IIT Kharagpur's aerospace engineering department, through its high-profile Kalpana Chawla Space Research Centre, is already spearheading crucial radar-related research along with Isro. "Such radar technology inputs can be utilized successfully for NI-SAR related research as well," said Alok Chatterjee, a Nasa scientist who is also a 1973 batch alumnus of the institute. He was accompanied by Paul Rosen, his colleague at Nasa.

The duo on Monday discussed with PP Chakraborty, the director of the institute, the possibilities of the institute starting a NI-SAR oriented collaboration with Isro soon. "This will automatically link up the institute with Nasa. In the NI-SAR research, there will be a radar that will collect data through two bands - the 'L' band that will be managed by Isro and the 'S' band to be handled by Nasa. The data will then be shared for final computations to determine tectonic movements of the earth that lead to earthquakes, tidal wave surge, melting of glaciers and rise in sea level," Rosen explained. "Such research will help in managing disaster to a large extent," he added.

"Since Isro chairman K Radhakrishnan is an IIT-Kharagpur alumnus, it will give added impetus to the collaboration," Chakraborty said.

NI-SAR is a multi-million dollar project that will be partially funded by Nasa and Isro. "If $73 and $83 million were spent on the Chandrayaan and the Mangalayaan projects, respectively, NI-SAR should cost around $100 million," Chatterjee explained.

NASA Delivers Precipitation Satellite to Japan for 2014 Launch : Washington

An international satellite that will set a new standard for global precipitation measurements from space has completed a 7,300-mile journey from the United States to Japan, where it now will undergo launch preparations.

 

A U.S. Air Force C-5 transport aircraft carrying the Global Precipitation Measurement (GPM) Core Observatory landed at Kitakyushu Airport, about 600 miles southwest of Tokyo, at approximately 10:30 p.m. EST Saturday, Nov. 23.

The spacecraft, the size of a small private jet, is the largest satellite ever built at NASA's Goddard Space Flight Center in Greenbelt, Md. It left Goddard inside a large shipping container Nov. 19 and began its journey across the Pacific Ocean Nov. 21 from Joint Base Andrews in Maryland, with a refueling stop in Anchorage, Alaska. 

From Kitakyushu Airport, the spacecraft was loaded onto a barge heading to the Japan Aerospace Exploration Agency's (JAXA's) Tanegashima Space Center on Tanegashima Island in southern Japan, where it will be prepared for launch in early 2014 on an H-IIA rocket.

"We have been building GPM hardware at Goddard for over four years," said Art Azarbarzin, GPM project manager, who traveled with the spacecraft on its flight to Japan. "We are excited now to get the spacecraft to Tanegashima and looking forward to the launch."

The satellite is designed to pool together precipitation measurements taken by a constellation of orbiting U.S. and international partner satellites, resulting in a single and comprehensive dataset of global precipitation every three hours.

The satellite will measure rain and snow using two science instruments: the GPM Microwave Imager (GMI) and theDual-frequency Precipitation Radar (DPR). The GMI captures precipitation intensities and horizontal patterns, while the DPR provides insights into the three-dimensional structure of rain, snow and other precipitation particles. Together, these two instruments provide a database of measurements against which other partner satellites' microwave observations can be meaningfully compared and combined to make a global precipitation dataset.

The GPM mission is a partnership led by NASA and JAXA. Goddard built and assembled the satellite. JAXA provided the DPR instrument and launch services. The Ball Aerospace & Technologies Corp., Boulder, Colo., built the GMI under contract to Goddard.

The GPM constellation is a network of satellites from multiple U.S. and international space agencies, including NASA, JAXA, the U.S. Department of Defense's Defense Meteorological Satellite Program, the U.S. National Oceanic and Atmospheric Administration; Japan; the Centre National d'Etudes Spatiales in France; the Indian Space Research Organisation; and the European Organisation for the Exploitation of Meteorological Satellites.

ISRO to launch French, German satellites : Chennai

*******************************************************



The Indian Space Research Organisation (ISRO), that got global recognition for its successful launch of a mission to Mars, will now launch German, French, British and Canadaian satellites, a top official said.

"We will be launching EnMAP (Environmental Mapping and Analysis Programme) satellite belonging to Germany. The satellite will weigh around 800 kg," ISRO chairman K. Radhakrishnan told IANS in an interview.

The EnMAP is a hyperspectral satellite that would provide images of the Earth at regular intervals. This apart, ISRO will be launching French satellite SPOT-7 during the first quarter of 2014, Radhakrishnan said.

"There will be four more small foreign satellites that would go along with SPOT-7," he added.

ISRO had launched the SPOT-6 satellite in 2012.

Radhakrishnan said discussions were held with British agencies for launching three satellites each weighing around 300 kg and also to launch a set of Canadian satellites. The idea is to have at least one commercial launch every year using the Indian Polar Satellite Launch Vehicle (PSLV), the ISRO chairman said.

According to him, the PSLV rocket's reliability has been underlined once again with the launch of Mars Orbiter in a precise manner despite the challenges.

Queried about the status of Mars Orbiter, he said: "The Orbiter has been raised to around 193,000 km apogee (farthest point from Earth). We are all gearing up for the dawn of Dec 1 when the Orbiter will be injected in trans-Martian orbit."

ISRO has been switching on the various systems and payloads of the Orbiter to check their functionalities and health.

"All the instruments are working normal. The satellite's health is good," Radhakrishnan said.

India launched Nov 5 its first inter-planetary mission to Mars with a two-fold objective - technological and scientific. The project outlay was around Rs.450 crore.

The technological objectives include design and realisation of Mars orbiter with a capability to survive and perform Earth-bound manoeuvres, cruise phase of 300 days, Mars orbit insertion/capture, and on-orbit phase around Mars.

It will also enable deep space communication, navigation, mission planning and management and incorporate autonomous features to handle contingency situations.

The scientific mission will be to explore the Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous scientific instruments.

Radhakrishnan said the Orbiter will be using around 365 kg on board fuel in the orbit raising activities out of around 850 kg fuel on board.

Comparing the latest Mars mission MAVEN of the US, Radhakrishnan said the American Atlas V rocket has a payload capacity of 13 tonnes to GTO (geo-transfer orbit) while the PSLV-XL capacity is only around 1,300 kg.

"The American satellite, weighing around 2,500 kg, carries payload weighing around 65 kg and around 1,600 kg fuel. Our Orbiter weighing 1,350 kg carries a payload of just 15 kg and fuel of around 850 kg," he added.

What he did not compare is the cost incurred in the both the missions. While India will be spending around $72 million the US mission is budgeted at $671 million.

Radhakrishnan reiterated that the Mars mission proves India's capability to undertake such complex tasks.
