ISRO launched 100th satellites in space ,and successfully placed Cartosat-2 in the Orbit.

ISRO  said that Polar Satellite Launch of Vehicle -C 40  (PSLV-C40) has successfully placed Cartosat-2 series Satellite into sun synchronous orbit .

The Indian Space Research Organisation (ISRO) on Friday successfully launched a Cartosat-2 series weather observation satellite, along with 30 other spacecraft, using its Polar Satellite Launch Vehicle (PSLV-C40), which lifted off from the Satish Dhawan Space Centre (SDSC) at Sriharikota, Andhra Pradesh.

PSLV successfully launches 31 satellites in a single flight. Isro’s Polar Satellite Launch Vehicle, in its 42nd flight, successfully launched the 710-kg Cartosat-2 series remote sensing satellite, along with 30 co-passenger satellites (January 12, 2018) from Satish Dhawan Space Centre, Sriharikota,” Isro said .

The PSLV-C40 successfully placed the Cartosat-2 series satellite in a sun synchronous orbit, Isro added.These successful launch comes about four months after Isro’s PSLV-C39 failed following a technical snag involving its heat shield.

From the side ISRO this is one of the best gift given to our nation in  a New year month,and Many big names given congratulation to the ISRO on the successful launched satellite . ISRO created a big history on the 1 month of the year which are joyful for the nation .

From the side of Prime Minister  Narendra Modi congratulated Isro scientists for the successful launch, saying the moment signified the country’s “bright future” in its space programme.

Benefits of India’s success are available to our partners. Out of the 31 satellites, 28 belonging to 6 other countries were carried by today’s launch,” Modi said.

“Isro is starting 2018 with the successful launch of our Cartosat small satellite, Nanosat and c and 28 customer satellites,” A.S. Kiran Kumar, Isro’s outgoing chairman, said after the launch.

The micro satellite built by Isro was placed in orbit after PSLV-C40 was brought down to 359.5km in a polar sun synchronous orbit. The fourth stage was finally shut off at 2 hours 21 minutes, thus making the mission the longest ever by Isro.

Top 10 Female Scientist of all time .

As we know very well that present generation of all over the world female contribution are increasing in the world.but if we see some generations ago, females were often looked down in the field of science and on other fields for that matter. But these ladies proved that in terms of brainpower, they can be greater than the ones on the masculine domain.Let us see world most popular female scientist of all time .

Marie Curie

From: Warsaw, Poland
Born: November 7, 1867
Died: July 4, 1934 (aged 66)

She was the first woman to win a Nobel Prize, the first one to win twice and the only person to win that prize in two different sciences. What’s even more remarkable about her is that she died due to the extreme radiation that she was exposed to, on all the years of her work. She always called as a heroine of that era , and she will be remembered as such, throughout the generations.

Rachel Carson

From: Pennsylvania, USA
Born: May 27, 1907
Died: April 14, 1964 (aged 56)

She was a marine biologist who devoted much of her time to some problems caused by synthetic pesticides. She was met with fierce opposition by chemical companies, but her achievement won everyone over as she garnered lots of awards and recognition from environment advocates all over the world.

Sally Ride

From: California, USA
Born: May 26, 1951
Died: July 23, 2012 (aged 61)

She stepped into a region where no American woman ever trekked before. As a physicist, she earned the favour of many influential persons which led her into becoming the first American woman to journey through outer space.

Grace Hopper

From: New York City, USA
Born: December 9, 1906
Died: January 1, 1992 (aged 85).

She was a navy admiral who also fought with her wits within the computer science community. Her work led to the development of one of the first high-level programming languages, a very crucial tool used by today’s computer programmers. She was given the nickname “Amazing Grace”by her collegues.

Rosalind Franklin

From: London, England
Born: July 25, 1920
Died: April 16, 1958 (aged 37)
She is the herald of understanding  crystals within the X-ray spectrum. Because of her findings, crystals became more than just glittering tiny objects – they became instrumental to our modern understanding of the DNA structure.

Ada Lovelace

From: London, England
Born: December 10, 1815
Died: November 27, 1852 (aged 36)

Computer programs make the world smaller and easier for us. Of course, they wouldn’t exist without a programmer, and we have Ms. Lovelace to thank for that because– she is the world’s first programmer. Working with Charles Babbage, the father of computing, she devoted her life to making her vision of computerization a reality.

Gertrude B. Elion

From: New York City, USA
Born: January 23, 1918
Died: February 21, 1999 (aged 81).

Initially she worked as a food quality supervisor at supermarkets in New York. But driven by the memory or her grandfather who died of cancer when she was 15, her desire to cure the disease burned bright once again.

Chien-Shiung Wu

From: Jiangsu, China
Born: May 31, 1912
Died: February 16, 1997 (aged 84).

Her expertise in experimental physics evoked comparisons to Marie Curie. This gave her the nickname “The Chinese Madame Curie.” She worked on the Manhattan Project, known to us now as one of the greatest scientific endeavors  in history.

Barbara McClintock

From: Connecticut, USA
Born: June 16, 1902
Died: September 2, 1992 (aged 90).

With her discovery of genetic transposition, she is the only woman to receive an unshared Nobel Prize in that category. She is a botanist by education and she used her proficiency on that field to further the understanding of genetics.

Lise Meitner

From: Vienna, Austria
Born: November 7, 1878
Died: October 27, 1968 (aged 89)

She was a nuclear physicist who worked tremendously on the complexity of radioactivity. Such a passion made her instrumental to the conception of the nuclear bomb which was used against Japan in 1945
