NASA and ISRO are doing an excellent job
Scientists have discovered
two new exoplanets, Kepler-90i and
Kepler-80g. This announcement was
made by the National Aeronautics and Space Administration (NASA) of the U.S.
Christopher Shallue, a software engineer at Google, and Andrew
Vanderburg, of the University of Texas, Austin, have discovered it using a deep
learning neural network — an artificial intelligence tool that mimics the
workings of a human brain. This is not also the first time that automation has
been used in identifying exoplanets. The Robotvetter program was the first
attempt at automating.
In the recent past we have seen exciting discovery of planetary system
using modern science and technology. Such scientific topics keep the mundane
politics away at least for some time. Human progress depends on scientific
thinking.
NASA also unveiled stunning ‘farewell image’ of Saturn. After more than
13 years at Saturn, and with its fate sealed, NASA's Cassini spacecraft bid
farewell to the Saturnian system. NASA has released a stunning view of the
Saturn and its splendid rings and moons, captured by the Cassini spacecraft. Cassini’s
scientific bounty has been truly spectacular - a vast array of new results
leading to new insights and surprises.
Farewell to Saturn’ will forevermore serve as a reminder of the dramatic
conclusion to that wondrous time humankind spent in intimate study of our Sun’s
most iconic planetary system. The
mission made numerous dramatic discoveries. Bit what these missions are adding
to welfare of mankind? Still we are not able to solve the problems of our own
planet.
Hope NASA will share such beautiful Images to the other Nations. It will
be a delight to watch to those who are interested in Astronomy.
While NASA is performing one great feat after another, the Indian Space
Research Organisation (ISRO) is not sitting quiet. ISRO is preparing to hand
over the entire gamut of launch vehicle manufacture to domestic industry by
2020. By 2020, we hope to have the first completely industry-built PSLV,
Ultimately, we hope to see industry make the transition from vendors
supplying parts, to partners providing integrated systems. ISRO already has a partnership with private
industry to produce satellites. ISRO had
a partnership with about 500 domestic industries for the supply of various
components and devices. About 80% of
the cost of launch vehicles and 40% of satellites are handled by these
industries.
There is the need for industry to reduce the manufacturing and material
cost without compromising on quality to bring down the launch cost. ISRO had tightened tolerance to error
following the failure of the PSLV- C39 mission. Reusable launch vehicles
promise to bring down launch cost but pose a problem for industry due to lower
demand. The solution is to create a market for more missions.
