The village that gave India its new ISRO chief…..DR.Sivan

A humble son of a farmer who studied in local government run schools, in Tamil medium, is the new head of India’s premier space agency.

Dr K Sivan was born in Sarakkalvilai in Kanyakumari district in 1957. His father was a farmer, and Dr Sivan is the first graduate in the family.

By all accounts, his is an unusual story.

A young Sivan studied in government schools in his native village till the 5th standard, and completed his schooling in neighbouring Valankumaravilai, all in Tamil medium. Later, he graduated from the S T Hindu College in Nagercoil.

He then graduated from the Madras Institute of Technology in aeronautical engineering in 1980 and completed his master’s in aerospace engineering from the Indian Institute of Science, Bangalore, in 1982.

That year he joined ISRO on its Polar Satellite Launch Vehicle project, towards which he contributed in mission planning, design, integration and analysis. He has held various responsibilities during his stint in ISRO, finally going on to head India’s space agency.

At ISRO, he completed his PhD in aerospace engineering from IIT-Bombay, in 2006.

Dr Sivan, who takes over from Dr A S Kiran Kumar on Monday, January 15, for a three-year term, is only the second rocket scientist after G Madhavan Nair to head ISRO.

Sarakkalvilai falls on the outskirts of Nagercoil, which is the headquarters of Kanyakumari district, Tamil Nadu. All of a sudden this small village has become the centre of attraction for people near and far, thanks to its famous son.

“Take the next right and it is at the end of the road,” says a villager, and as you reach the house you realise it is as unpretentious as the man who grew up there.

Dr Sivan’s sister-in-law Saraswathi lives in the family house with her daughter. “My eldest daughter got married five months ago and Sivan had come for the function,” she says, her eyes glowing with happiness.

Since the announcement about his appointment, people have been coming in droves to congratulate her, and her face beams with pride.

“I was married 30 years ago into this family and at that time he was already working for ISRO in Thiruvananthapuram. He used to live in a lodge then. He comes home for festivals and family functions,” says Saraswathi.

The conversation is interrupted when former Tamil Nadu Congress president Kumari Ananthan lands up with a dozen supporters to congratulate her.

One of the men who comes along with Ananthan hands her a book with the message, “Please give it to him when he comes next.” Another hands her a monthly magazine.

“He comes here every year for the Badrakali Amman puja which takes place in April-May,” adds his sister-in-law.

“He comes with his family, offers prayers and leaves the same day. He always comes for all family functions. When he is with the family he is always smiling and joking. He never calls, but his wife calls regularly and keeps in touch with us,” Sarawathi says.

“He was a class topper from school to college,” says Dr Sivan’s uncle who lives in the house opposite.

“He was a brilliant student and never went for tuitions or private classes. His father used to pluck mangoes and young Sivan used to go to the market to sell it. He was a helpful child,” the uncle adds.

The school Dr Sivan studied at is also opposite the family house. The retired PT master there recalls him clearly. “He was five years my junior in school, I remember him as a very quiet boy.”

“I too was five years his junior,” another villager pipes in. “You know the final exams used to come during harvest time. His father used to be in the field while Sivan sat on the lower branch of a tree with his books, studying, keeping one eye on the harvest, and run if his father called. He was always studying.”

“When Sivan and I were in school we had a very good headmaster,” the villager adds. “That headmaster planted many trees in the school compound and made every class in charge of a few trees. In the morning, when we came to school, the first thing we did was to water the trees and only after that did we attend school.”

“Kanyakumari is basically an agricultural district,” an elderly villager points out. “Apart from coir, there was no industry here. We all survived on farming. It’s rich fertile soil and there is plenty of water. Paddy, bananas, coconuts, mangoes, rubber is grown here.”

“Sivan was exceptional,” the elderly gent adds, “while he helped his father in the field he continued studying every free moment.”

“As there was only a primary school here we went to nearby Valankumaravilai for our SSC (Class 10). Those days there was no 12th standard. As there was no bus facility we walked.”

A colleague from ISRO, who retired a decade ago and did not want to be named for this feature, recalls, “He (Sivan) would go home only to sleep. He is extremely hard-working and totally focused on his work. He was not only the first graduate from his family, he was also the first graduate from his village.”

“He is a disciplined taskmaster,” says D Karthikesan, former director of the ISRO Propulsion Complex in Mahindragiri, Tamil Nadu.

“He likes to keep everything on schedule and works with a deadline,” adds Karthikesan. “If he thinks there is a problem somewhere he will go and talk to the people actually working on the project, and never limit himself to seniors in the organisation.”

“Though he is a hard taskmaster,” the former ISRO scientist points out, “he is also extremely generous and always looks after the welfare of the people working under him. So people work hard for him.”

“He is a bold decision-maker,” says Karthikesan. “Where others may hesitate wondering if it would work or not, he will say it will work and will do it.”

“Though he followed the schedule strictly,” adds Karthikesan, “he also made sure that all parameters are met at every stage. Whether it is quality or safety, he made sure every parameter was up to the mark before proceeding, and yet kept a tight schedule.”

Dr Sivan has two sons. The elder one has finished his BTech, the younger son is in college.

The school Dr Sivan studied in was built over 60 years ago. “We need to pull it down and build another,” says a villager. A government-run school, the land was given free by Dr Sivan’s uncle.

The village still does not have a bus service, a fact the villagers highlighted to Kumari Ananthan, the Congress politician. Nor does it have a middle, high or higher secondary school.

K Sivan’s ascent bears an uncanny resemblance to another ISRO scientist who was born in a fishing village in Ramanathapuram, also in Tamil Nadu.

That scientist, of course, went on to become the most beloved President this Republic has had.

Image of the Day…” Liftoff at NASA’s 16th Annual Student Launch Challenge…”

Liftoff of one of dozens of high-powered rockets during the 16th annual Student Launch challenge, April 16, near NASA Marshall

One of dozens of high-powered rockets lifts off on April 16, 2016, during NASA’s 16th annual Student Launch challenge, held near Marshall Space Flight Center in Huntsville, Alabama from April 13-16.

Nearly 50 middle and high school, college and university teams from 22 states competed in the challenge, demonstrating advanced aerospace and engineering skills related to real-world activities and programs on NASA’s Journey to Mars. Teams spent the past eight months building and testing rockets designed to fly to an altitude of one mile, deploy an automated parachute system, and land safe enough for reuse, while other teams also designed scientific payloads for data collection during flight.

Preliminary winners for Student Launch were announced during an awards ceremony April 16, at the U.S. Space & Rocket Center in Huntsville, and hosted by Orbital ATK. The overall winners of Student Launch will be announced in early May, as the final calculations are still under review for accuracy.

Image of the Day…Mars Rover Opportunity up high ….!!!

Mars rover up high, spies a dust devil

After making the steep-ever climb of any rover on Mars, Opportunity looked back along its own tracks toward a swirling Martian dust devil in the valley below.

From its perch high on a ridge, NASA's Mars Exploration Rover Opportunity recorded this image of a Martian dust devil twisting through the valley below. The view looks back at the rover's tracks leading up the north-facing slope of

View larger. | From high on a ridge, NASA’s Mars rover Opportunity recorded this image of a swirling Martian dust devil on March 31. Image via NASA/JPL-Caltech.

During its recent uphill drive to the top of Knudsen Ridge on Mars, the tilt of the Mars Opportunity rover reached 32 degrees, the steepest-ever for any rover on Mars. In this image – taken on March 31, 2016, the 4,332nd Martian day, or sol, of the rover’s work on Mars – you’re looking backwards along the rover’s tracks, with its camera aimed toward a dust devil twisting through the valley below.

In the image, the rover – which was launched from Earth in 2003 – has just climbed the north-facing slope of Knudsen Ridge on Mars. The ridge forms part of the southern edge of Marathon Valley.

Why is NASA’s image in black and white, by the way? It’s because it was taken with the Navcam on Opportunity, a camera that’s essential for enabling the rover to make its way across the surface of this alien world … but which doesn’t have a color camera.

Look below to see how artist Don Davis remedied the lack of color with some processing here on Earth:

NASA commented:

Dust devils were a common sight for Opportunity’s twin rover, Spirit, in its outpost at Gusev Crater, but Opportunity has seen them only rarely.

Just as on Earth, a dust devil is created by a rising, rotating column of hot air. When the column whirls fast enough, it picks up tiny grains of dust from the ground, making the vortex visible.

Image of the Day…” Busy Traffic at International Space Station …” !!!

Docked Soyuz spacecraft in center of frame with Cygnus cargo craft at left and Progress craft at right with Earth below

Expedition 47 Flight Engineer Tim Peake of the European Space Agency took this photograph on April 6, 2016, as the International Space Station flew over Madagascar, showing three of the five spacecraft currently docked to the station. The station crew awaits the scheduled launch today, April 8, of the third resupply vehicle in three weeks: a SpaceX Dragon cargo spacecraft, which will be the sixth spacecraft docked following its arrival and installation to the Harmony module on Sunday, April 10. Dragon is carrying 6,900 pounds (3,130 kilograms) of science, crew supplies and hardware; the largest payload is theBigelow Expandable Activity Module (BEAM). The BEAM will be attached to the Tranquility module a week after its arrival for a series of habitability tests over two years.

Orbital ATK’s Cygnus cargo craft, visible at the left of this image, was bolted into place on the Earth-facing port of the station’s Unity module on March 26, 2016. Although the SpaceX and Orbital ATK spacecraft have made 12 launches between them, this will be the first time that the two vehicles, contracted by NASA and developed by private industry to resupply the station, are connected to the space station at the same time.

Image of the Day… Lunar shadow across Earth..

Lunar shadow moves across Earth

This is way cool. Watch the moon’s shadow move across Earth during the March 9 total solar eclipse. A first ever animation from deep space.

A camera aboard the DSCOVR satellite captured a unique view of this week’s solar eclipse. On March 9, 2016, residents of the Western Pacific looked up in the early morning hours to observe the only total solar eclipse of 2016, while DSCOVR looked down from a million miles away and captured the shadow of the moon crossing the planet.

In the animation above, the shadow of the new moon starts crossing the Indian Ocean and marches past Indonesia and Australia into the open waters and islands of Oceania (Melanesia, Micronesia, and Polynesia) and the Pacific Ocean. Note how the shadow moves in the same direction as Earth rotates. The bright spot in the center of each disk is sunglint — the reflection of sunlight directly back at the satellite’s camera.

NOAA’s DSCOVR satellite is the Nation’s first operational satellite in deep space. DSCOVR hovers between the sun and Earth at all times, maintaining a constant view of the sun and sun-lit side of Earth.

Adam Szabo is NASA’s project scientist for DSCOVR. He said:

What is unique for us is that being near the sun-Earth line, we follow the complete passage of the lunar shadow from one edge of the Earth to the other. A geosynchronous satellite would have to be lucky to have the middle of an eclipse at noon local time for it. I am not aware of anybody ever capturing the full eclipse in one set of images or video.

The animation above was assembled from 13 images acquired on March 9, 2016, by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four-megapixel charge-coupled device (CCD) and Cassegrain telescope on the DSCOVR satellite.

Japan’s Himawari-8 satellite also captured a series of images showing the procession of the shadow during this eclipse, which you can view here.

Bottom line: On March 9, 2016, a camera aboard the DSCOVR satellite captured the shadow of the moon crossing Earth from a million miles away during the only total solar eclipse of 2016.

This date in science: John Glenn first American to orbit Earth….

On February 20, 1962, John Glenn became the first American to orbit the Earth. He made three turns around the planet before returning safely.

John Glenn and Friendship 7

February 20, 1962. John Glenn became the first American to orbit the Earth on this date. He made three turns around the planet before returning safely in his space capsule, which was called Friendship 7. He followed two Russian cosmonauts in making this early orbit of our planet: Yuri Gagarin ( April 1961) and Gherman Titov (August 1961).

While Glenn was in orbit, NASA controllers received an indication that the heat shield on his craft had come loose. They instructed Glenn not to jettison the rockets underneath the heat shield during re-entry, because the rockets might be able to hold the shield in place. Fortunately, the indication turned out to be a false alarm.

Glenn returned to space at age 77 aboard the space shuttle Discovery in 1995, making him the oldest person to fly in space. His mission’s primary scientific aim at that time was to study the effects of spaceflight on seniors.

John Glenn and Friendship 7

Here's What John Glenn saw on February 20, 1962.  Just 5 minutes and 44 seconds after launch, Glenn offered his first words about the view from his porthole: “This is Friendship 7. Can see clear back; a big cloud pattern way back across towards the Cape. Beautiful sight.” Three hours later, at the beginning of his third orbit, Glenn photographed this panoramic view of Florida from the Georgia border (right, under clouds) to just north of Cape Canaveral. His American homeland was 162 miles (260 kilometers) below. “I have the Cape in sight down there,” he noted to mission controllers. “It looks real fine from up here. I can see the whole state of Florida just laid out like on a map. Beautiful.”  Image via NASA
