Flower Tower of Paris…

In Paris’s 17th arrondissement is a 10-story apartment building that’s so completely covered with potted plants that the building itself is invisible. Each flower pot is dense with foliage from rapidly growing bamboo plants. With 380 such irregularly spaced flower pots lining the balconies on three sides of the building, the entire apartment block appears to be a giant display of potted plants.

The building called “Flower Tower” was designed by Edouard François, who drew inspiration from Parisians who habitually cultivate even the most tiniest balcony, nurturing surprising greenery in this tightly packed, densely occupied city.

The pots are fixed to the balconies and fed by an automatic watering system to ensure that the plants do not die during the long holidays and in the height of summer. Bamboo was chosen because it is a hardy and fast growing plant, but also because it makes a noise in the wind, “giving the impression to those inside that they are sleeping in a tree” explained Edouard François.

Image of the Day… Cloud Shadow

The sun is behind the cloud. It looks as if the shadow is also behind the cloud, but that’s just a trick of perspective.

Asthadi Setyawan in Malang, East Java, Indonesia posted this photo at EarthSky Photo on G+. What you see here is the shadow of a cloud. The great sky optics expert Les Cowley – of the website Atmospheric Optics – calls them the inverse of crepuscular rays and notes they can produce dramatic effects.

We asked Les why it appears that this shadow is on the wrong side of the cloud. It looks from the photo as if the sun and the shadow are both behind the cloud. He told EarthSky:

It only looks that way. The shadow is closer to the camera than the cloud. Rays from the sun 93 million miles [150 million km] away are (nearly) parallel and always downward pointing. The shadows can be through misty or hazy air, or, sometimes, they’re cast on a lower thin layer of cloud that is otherwise invisible.

Check Les’ website for diagrams that explain the two cases here and here.

Dione and Enceladus

Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. As a result, it appears brighter against the dark night sky.

The surface of Enceladus (313 miles or 504 kilometers across) endures a constant rain of ice grains from its south polar jets. As a result, its surface is more like fresh, bright, snow than Dione’s (698 miles or 1123 kilometers across) older, weathered surface. As clean, fresh surfaces are left exposed in space, they slowly gather dust and radiation damage and darken in a process known as “space weathering.”

This view looks toward the leading hemisphere of Enceladus. North on Enceladus is up and rotated 1 degree to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 8, 2015.

The view was acquired at a distance of approximately 52,000 miles (83,000 kilometers) from Dione. Image scale is 1,600 feet (500 meters) per pixel. The distance from Enceladus was 228,000 miles (364,000 kilometers) for an image scale of 1.4 miles (2.2 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

Image of the Day…”Fingerprints of Water on the Sand.”…..

Water tracks on sandy ground with straight lines of roadways crossing the terrain

NASA astronaut Kjell Lindgren took this photograph on Nov. 11, 2015 from the International Space Station, and shared it with his followers on social media. Lindgren wrote, “The delicate fingerprints of water imprinted on the sand. The #StoryOfWater.” The area photographed is located in Oman, approximately 20 km to the west-northwest of Hamra Al Drooa.

One of the ways research on the space station benefits life on Earth is by supporting water purification efforts worldwide. Drinkable water is vital for human survival. Unfortunately, many people around the world lack access to clean water. Using technology developed for the space station, at-risk areas can gain access to advanced water filtration and purification systems, making a life-saving difference in these communities. Joint collaborations between aid organizations and NASA technology show just how effectively space research can adapt to contribute answers to global problems. The commercialization of this station-related technology has provided aid and disaster relief for communities worldwide.

Image of the Day…China’s New Radio Telescope…FAST

The construction of FAST – China’s new radio telescope – is proceeding on schedule. When completed in 2016, it’ll be the largest radio telescope in the world

View larger. | Five hundred meter Aperture Spherical Telescope (FAST) in China.

Five hundred meter Aperture Spherical Telescope (FAST) in China.

The Five hundred meter Aperture Spherical Telescope (FAST) – now under construction in southwest China’s Guizhou Province – is going well. Construction began in 2011 and is set to be completed by September, 2016. When completed, China’s new radio telescope will be the largest in the world.

As its name suggests, this new radio telescope will have a diameter of 500 meters (1,600 feet). That’s in contrast to the Arecibo radio telescope in Puerto Rico, which is 305 meters (1,000 feet) across.

Like Arecibo, the new ‘scope lies within a natural hollow, or karst, in the landscape. When finished, it’ll have 4,600 triangular panels for reflecting and focusing the radio waves. Unlike Arecibo, which has a fixed spherical curvature, FAST will use active optics. Its surface will adjust in different directions with more flexibility than the surface of Arecibo. That means it’ll cover the sky within 40° from the zenith, or overhead point, in contrast to Arecibo’s 20° range.

A possible application is to listen for radio waves from other advanced civilizations, but there are many astronomical questions as well, which the telescope will help answer.

Li Di, the chief scientist of the National Astronomical Observatories Chinese Academy of Sciences,said:

FAST will remain the best in the world in the next 20 to 30 years after it is completed. FAST can answer questions not only limited to astronomy but questions about humanity and nature. The scientific potential of this telescope is hard to predict.

Bottom line: The Five hundred meter Aperture Spherical Telescope (FAST) in China is progressing on schedule and should be completed in September 2016.

ISRO Celebrated Diwali with Its Own Rocket – Indigenously Made Communications Satellite GSAT-15 ….

At exactly 3:04 am on November 11, at the Kourou spaceport in distant French Guyana in South America, the Indian Space Research organisation (ISRO) gave India it’s Diwali gift. It successfully launched an indigeneously made communications satellite GSAT-15, using one of the world’s largest rockets – the Ariane-5.

Then, after a flight of 43 minutes and 24 seconds, GSAT-15 separated from the Ariane 5 upper stage in an elliptical geosynchronous transfer orbit (GTO). The ISRO Master Control Facility at Hassan, Karnataka, took over the command and control of GSAT-15 after its separation from the launch vehicle.

An Arabsat communications satellite also accompanied the GSAT-15 on the same launch.

Made at a cost of Rs. 278 crores, the GSAT-15 satellite weighs 3164 kg. With 24 transponders in the ku band, GSAT-15’s primary role will be to boost direct-to-home (DTH) broadcasting.

It will also enhance the GPS-aided augmented navigation (GAGAN) payload operating in L1 and L5 bands, which will help in aircraft navigation. GSAT-15 also provides a replacement for the Ku-band capacity of INSAT-3A and INSAT-4B satellites, which are getting ready to retire. GSAT-15 has a life of 12 years.

Currently, India has a shortage of transponders in space. The Indian satellite system is only able to handle a third of the required capacity, with the rest being leased from foreign satellite companies.

“The launch of GSAT-15 will be one more step towards further strengthening the satellite navigation infrastructure and sustaining the communication infrastructure in the country,” said ISRO Chairman A S Kiran Kumar.

The New Horizons spacecraft looked back to a crescent Pluto, after sweeping past this world in July, 2015. The sun is behind Pluto in this image. New Horizons acquired the view using the Multispectral Visible Imaging Camera (MVIC) onboard.

Here, Pluto’s ice mountains Norgay Montes and Hillary Montes can be seen rising as high as approximately 11,000 feet (3,500 meters) above Pluto’s surface. The so-called Sputnik Planum within the Tombaugh Regio stretches to the horizon on the right.

The frigid, very thin, cold atmosphere is seen with layers of haze. The average surface temperature of Pluto is minus 367 Fahrenheit (minus 232 Celsius). If our own Earth cooled to the same temperatures, our oceans would freeze almost all the way down and our atmosphere would collapse and freeze into a layer of frozen gasses 35 feet (11 meters) thick.

 

Bottom line: As New Horizons sped past in July, it looked back to a crescent Pluto.

Scott Kelly on the Second Spacewalk of Expedition 45……

On Nov. 6, 2015, NASA astronauts Scott Kelly and Kjell Lindgren spent 7 hours and 48 minutes working outside the International Space Station on the 190th spacewalk in support of station assembly and maintenance. The astronauts restored the port truss (P6) ammonia cooling system to its original configuration, the main task for the spacewalk. They also returned ammonia to the desired levels in both the prime and back-up systems. The spacewalk was the second for both astronauts. Crew members have now spent a total of 1,192 hours and 4 minutes working outside the orbital laboratory.

At about an hour after the 6:22 a.m. EST start of the spacewalk, astronaut Kjell Lindgren took this photograph of Scott Kelly at work, with the station’s solar arrays visible in the background.

The Go-Getters of Dharavi , Mumbai….

Even as plans to redevelop Dharavi continue to gather dust in government files, its young residents have chalked their own course and chosen to fly high. Hepzi Anthony recounts a few inspiring tales.

Other slums may have laid claim to its tag of being Asia’s largest slum, but within Dharavi are stories of India shining despite its squalor, of grit, determination and fighting against odds to overcome barriers.

Transformation is in the air in Dharavi today, and it is not just physical.

Change is manifest not just in the form of the superficial replacement of slums with buildings or in terms of better quality roads, improved hygiene or even the ATMs coming up there; it is evident from the sharp rise in the socio-economic profile of the average Dharavi resident that has seen a massive upsurge.

Indeed, the story of Dharavi today is of not just buildings replacing the slums but the rise of a new generation that is clearly more educated, more informed and more affluent, too.

As a new generation comes up, the success stories from India are now being replaced by stories of its residents working, studying and even settling down in foreign shores.

From being a symbolic representation of the daily struggle for survival of the urban, migrant and Indian poor in Hollywood films, many people raised there now literally crisscross continents for work or study.

Some, like Jasmine Jacob, discovered that her humble origins and surroundings could not clip their wings of ambition.

Her fascination for the scientific world saw her do research in Nanotechnology and take off to countries like the United States and France.

After completing her post-graduation in chemistry from the Institute of Science, Mumbai, she was for a Department of Atomic Energy scholarship that enabled her for a doctoral study of nanosciences at the Bhabha Atomic Research Centre.

Her superior performance there further earned her a government-funded post-doctoral research study trip to Paris for 15 months.

From there on she moved on to do another course at the University of Notre Dame at Indiana, US. Incidentally, her entire higher study was done entirely with the help of scholarships.

Having found her dream, Jasmine Jacob now inspires the children of Dharavi to dream big and pursue their ambitions.

“Money is not everything. I am a good example of how if you are prepared to work hard, and you have it in you, nothing can stop you,” says Jacob.

Her father, who worked in a private firm and was the sole bread earner in her family, could not afford to pay her fees for higher studies.

“But my teachers ensured that my studies were not affected. They knew of my background and went out of their way to help me. They supported me by finding out and recommending me for scholarships,” she says.

Currently, she is doing research in nanotechnology and continues to reside in Dharavi, though her family has now shifted to a building there.

“Till my third standard, we stayed in a tin house that would be roughly about 10×10 sq ft and then we moved into a brick house. There were lots of infrastructure issues at home and around. It was impossible to study at evenings as everyone would be watching television and there would be so many distractions around,” she recalls.

Having found her dream, Jacob now wants to inspire other students, especially from her locality, to dream big and pursue their dreams.

Not to convent schools where the rich children go, she prefers to go to her former alma mater Kamaraj Memorial School at 90-ft Road to deliver motivational talks to students. Jacob had studied here in Tamil medium till the fourth standard and thereafter shifted to English medium in the same school.

She tells her students to concentrate on their studies and not get scared of the roadblocks on the pathway to their dreams.

“I was so focused and good at my studies that I did not know many students in my class. But, my co-students knew me and wanted to befriend me for my notes. My locality did not matter to anyone,” she says.

Jacob says she never dreamt of working or staying abroad and did not fancy a high-paying job or the lifestyle there.

“I always wanted to be in India and am happy to be here,” she signs off.

Amolik Selvaraj is quite open to the idea of staying in Dharavi even now. But he is practical enough to know that it would not be that easy for his family.

Her view is shared by Amolik Selvaraj, who also crisscrossed the US and the United Kingdom before returning to Pune for work.

Brought up in Dharavi, 46-year-old Selvaraj started working as a data entry operator while graduating from the Dr Ambedkar College in central Mumbai’s Wadala locality.

Along with studies and work, he took to learning computer software languages like Clipper, Foxpro, VB.NET and C#.NET.

This helped him get offers to work as a systems programmer and got him a breakthrough in Maryland, US, in 2007 for about two years. Thereafter, he shifted to quality assurance that kept his career on a high and helped him move to other countries.

In 2011, he moved on to work in Didcot, Oxfordshire, in the UK for a little over a year.

Recently, he shifted to Pune where he works as a senior consultant at Systems Plus Technologies.

Despite staying abroad for many years and having visited places like Washington, London and Oxford, Selvaraj says that he is quite open to the idea of staying in Dharavi even now.

In fact, he continues to emotionally connect with the place and to date his passport and Aadhar card still bear his Dharavi address.

“One of the things about Dharavi is that one would end up running into so many people just like that. Abroad, people never turn up impromptu at your place. They would almost always turn up only after fixing an appointment. The doorbell never rings without one knowing who would be at the door.

“Also, I have lost my spiritual connect after I shifted out of Dharavi. There, I could just walk over to the open church nearby almost any time of the day,” says Selvaraj.

But he is practical enough to know that it would not be that easy for his family.

“Were it not it for factors like my children’s education and good influence, I would have happily shifted back to Dharavi. Things have changed so much now. ATMs are accessible there and the facilities are much better now,” he says.

 

Reverend Samuel Christudoss, ex- parish priest of Good Shepherd Church, Dharavi, who has resided in and has been observing the area for over a decade, notices: “It is almost routine to hear old people talking about their children being in the US or Germany these days. Apart from those settled abroad, many people travel abroad regularly for work or for study projects. The new generation has lapped up higher education like never before with the result that almost everyone is literate here now.”

The prosperity has percolated downwards too.

“Long back, when I had to live in Dharavi around 1991, I recall being provided with just mats to sleep with bricks for pillow by the church because the people there themselves lived with such basic, primitive means.

“I would be hauled up even if I took a cab for travelling (autorickshaws are not allowed in Dharavi) and questioned as to why I did not walk the distance. Today, when I am re-posted in this place, I see a marked difference here. The very same church now allows me the option of travelling by air-conditioned cabs, a direct result of the younger generation being exposed to a higher standard of living,” he observes.

So, while the much-touted Dharavi Redevelopment Plan continues to gather dust in the files or drawing boards of the Maharashtra government, the people of Dharavi have chalked their own course and risen to fly up high beyond the boundaries of the nation.
