New York: An Indian-origin scientist’s proposal has been selected for NASA’s Innovative Advanced Concepts (NIAC) programme — an initiative that invests in transformative architectures through the development of pioneering technologies.
Ratnakumar Bugga from NASA’s Jet Propulsion Laboratory in Pasadena, California, is among 13 other researchers who will be awarded nearly $100,000 for nine months to support the initial definition and analysis of their concepts, the US space agency said in a statement on Saturday.
If the basic feasibility studies are successful, awardees can apply for phase-two awards, valued up to $500,000 for two additional years of concept development.
Bugga’s concept is titled “Venus Interior Probe Using In-situ Power and Propulsion.”
The India-born scientist who has PhD in electrochemistry from the Indian Institute of Science, Bengaluru, is currently involved in the development of low temperature lithium-ion rechargeable batteries and in the ultra-low temperature Li primary batteries for Mars probes.
He leads a task force responsible for demonstrating the technology readiness of lithium-ion batteries for Mars missions.
Bugga was the task manager for the Mars Exploration Rover Thermal, Rover and Lander batteries.
Other selected concepts include a proposal for reprogramming micro-organisms that could use the Martian environment to recycle and print electronics and a two-dimensional spacecraft with ultra-thin subsystems that may wrap around space debris to enable de-orbiting.
There are many international organizations that have been working to save our planet from many harms of deforestation but there is one Indian man who, single-handedly, gave rise to the forest in 1360 acre land and converted it into the man-made forest in India and that man is Jadav Molai Peyang.
Jadav Peyang’s story was first discovered by journalist Jitu Kalita when he was stalking the vultures on the other end of Arun Sapori, an over 1,000-hectare riverine island on the Brahmaputra when he saw the forested area and found Peyang’s story there.
The forest man has planted over 1500-saplings since 1980 which has grown into the famous, Molai Kathoni, the forest famously named after his maker. Peyang had started this initiative as a teenager who started planting bamboo in the woodland after he had witnessed deaths of several snakes at the shore when water had resided from the area after a flood. Following that horrifying scenario, he sought the advice from the village elders who asked him to grow a forest as only the forest can save the lives of birds and animals. Since then, Peyang’s Molai Forest has developed its own ecosystem as deer, rabbits, rhinoceros, Bengal tigers, birds, insects have inhabited the forest which consists of trees such as Bamboo, valcol, Arjun, Pride of India, silk trees, cotton trees, to name a few. But it was a herd of 100 elephants that brought the attention of Assam’s forest department on Peyang in 2008. The elephants pay a yearly visit to his forest and give birth to their calves in the comfort there.
But the journey of creating a barren sandbar in the middle of the river Brahmaputra of Assam into the thriving forest that it is today wasn’t easy.
In the initial stages, he found planting trees extremely difficult and time-consuming but now as he gets the seeds from the trees, the forest seems to live on itself.
The forest man was the first part of the 5-year project launched by the Assam Forestry Division in Aruna Chapori in 1980 with an aim to reforest two hundred hectares of land. Peyang enrolled for the job and started planting trees for the project though, the project was finished in five years, Peyang had stayed and spread his own project bigger than Central Park, NYC (842.6 acres). Since his first project, he has been invited to several environmental conferences, conferred many honors among which is Padam Shri, the highest civilian award and ‘Forest Man of India’ by JNU along with the recent honor bestowed on Jitu Kalita and Jadav Peyang by Taiwan Government for their efforts.
The forest man’s story is full of inspiration and compassion as he keeps providing shelter to various insects and animals while his family, which consists of two sons, a daughter, and his wife subsides on the income provided by their livestock, there is a lot to learn from him. He had braved several threats and all he has to say to them, ‘Kill me first, before you kill my forest,’ but his ideas for the world remains unknown among the several honors.

Sue Finley, now 80 years old and NASA’s longest-serving female employee, recalls her early days with the space agency when she worked as a human “computer,” calculating rocket trajectories by hand at a time when computers were huge and expensive to operate.
Finley arrived at Jet Propulsion Laboratory (JPL) in Pasadena, California, in January 1958, one week before the U.S. Army launched Explorer 1, America’s first earth satellite.
“It was a very big deal,” she recalls of the launch, a response to the launches a few months earlier of the first satellites, Sputnik 1 and 2, from the former Soviet Union.
She was at JPL for Pioneer 1, the first satellite sent aloft by the newly formed National Aeronautics and Space Administration (NASA) in late 1958, which marked the beginning of the international space race.
Unmanned space probes
Since then, Finley has had a role in nearly every U.S. unmanned space probe, and some missions of other nations.
There were failures to overcome and spectacular successes, but always new goals as scientists expanded our knowledge of the earth and solar system.
“We were certainly proud,” she says of NASA accomplishments, “but you just go to the next thing.”
Finley has been through several career changes with the space agency, one of the most important when NASA phased out human computers, moving, initially, to simple electronic versions.
“We got little tiny computers,” she recalls. “One I had 16 wires, jumper cables to code with. One had 10 pegboards that you programmed with.”
As modern computers took over navigational tasks, Finley developed and tested software as a subsystem engineer.
Among her career highlights: the Vega mission, a Soviet-French collaboration with Venus, and Halley’s Comet, which received navigational help from NASA and dropped balloons into the atmosphere of Venus.
She had to change the software for the antenna that tracked the mission, “and it worked,” Finley recalls. “Everything worked. That’s what was so exciting!”
Finley has worked since 1980 on NASA’s Deep Space Network, which coordinates satellite facilities in California, Spain and Australia that allow communication with space probes.
Highlights of NASA career
Career highlights include developing software that generates audio tones sent back from spacecraft, informing engineers on the ground what is happening in space. It was first developed for the Mars missions.
Each tone has a meaning that communicates data, noted one of Finley’s colleagues, Stephen Lichten.
“If a parachute opened, it would send a tone,” Lichten, manager for special projects for the Deep Space Network, said.
“The spacecraft lets go of its heat shield, and it would send a different tone, and so engineers like Sue were here listening for those special frequencies which told them the spacecraft was telling them what it has just done,” he said.
He notes that Finley also helped develop communication arrays that combine multiple antennas to act in unison and other advances that now crucial to space missions.
Lichten once shared an office with Finley and says she inspired her younger colleagues.
“There was a parade of people coming in constantly, to ask her advice, to ask her questions,” he recalls. “This was during the Venus balloon mission days and I realized that Sue was regarded as sort of a guru at JPL.”
Finley has been involved with nearly every advance in space communications in recent decades, and she continues her work today, Lichten said.
There are many more women at NASA today than there were when she started, and Finley said she tells young women to be inquisitive.
“I tell them to never be afraid to ask questions, never be afraid to say you don’t know,” she said.
After nearly six decades at the space agency, a mother of two grown sons and a mentor to her colleagues, Finley has no plans of retiring.
“There’s nothing else I want to do,” she said. “And so far, they need me.”

Florida, November 19, 2017: NASA captured 20 years of changing seasons on Earth in a striking new global map of the home planet.
The data visualization, released this week, shows Earth’s fluctuations as seen from space.
The polar ice caps and snow cover are shown ebbing and flowing with the seasons. The varying ocean shades of blue, green, red and purple depict the abundance — or lack — of undersea life.
“It’s like watching the Earth breathe. It’s really remarkable,” said NASA oceanographer Jeremy Werdell, who took part in the project.
Two decades — from September 1997 to this past September — are crunched into 2½ minutes of viewing.
Werdell finds the imagery mesmerizing. “It’s like all of my senses are being transported into space, and then you can compress time and rewind it, and just continually watch this kind of visualization,” he said Friday.
Werdell said the visualization shows spring coming earlier and autumn lasting longer in the Northern Hemisphere. Also noticeable to him is the receding of the Arctic ice caps over time — and, though less obvious, the Antarctic, too.
On the sea side, Werdell was struck by “this hugely productive bloom of biology” that exploded in the Pacific along the equator from 1997 to 1998 — when a water-warming El Nino merged into cooling La Nina. This algae bloom is evident by a line of bright green.
In considerably smaller Lake Erie, more and more contaminating algae blooms are apparent — appearing red and yellow.
All this data can provide resources for policymakers as well as commercial fishermen and many others, according to Werdell.
Programmer Alex Kekesi of NASA’s Goddard Space Flight Center in Maryland said it took three months to complete the visualization, using satellite imagery.
Just like our Earth, the visualization will continually change, officials said, as computer systems improve, new remote-sensing satellites are launched and more observations are made. (VOA)
