Remembering the legend; An Inspiration to the young generation : Dr.A P J Abdul Kalam

Our beloved former president Dr.A P J Abdul Kalam may have left for his heavenly abode but will always continue to rule & guide innumerable young minds he interacted with. Despite occupying the highest office of the land, he had a vision for the country for which he made relentless efforts with an eye on future. He has planted his dreams in our present generation as he hosted and talked to the school and college students in the Rashtrapati Bhawan. I also happened to attend one such session with the honourable president. His childlike enthusiasm for rapid growth of the nation & development of scientific temperament was there for all to feel.

I sincerely hope that the seeds sown by Dr.A P J Abdul Kalam will bear fruits in the form of growing scientists, statesmen, teachers, scribes, professionals,intellectuals, honest politicians…….and great citizens of India which was always close to hi heart.

It is the time for every citizen of India in general & students in particular to open leaves from his life and try to imbibe the idels he lived for.

Given below is a link to 10 great lessons we can learn from his life….

Another historic moment in space exploration….PLUTO HAS A HEART TOO………

For the first time, man will have a close look at Pluto; once a planet of our solar system.

A photograph shows that the planet has a huge heart shape on its surface…Read on for details…

http://www.washingtonpost.com/news/speaking-of-science/wp/2015/07/09/now-pluto-has-a-heart-on-it/

The pictures have been taken by a tiny probe NEW HORIZONS launched by NASA in 2006.

The tiny probe had a 3 billion mile journey to Pluto on a FLYBY mission.

If everything goes to plan, it will be a staggering technological accomplishment. Pluto is the farthest destination for any space mission in history. It took New Horizons nine years to cover the 3 billion mile trip there — which means it’s currently using decade-old technology, traveling a route that was calculated years ago. And because New Horizons is traveling at such a high speed (about 31,000 miles per hour) and can’t slow down, the flyby will be over in a matter of minutes.

Pluto was officially a planet when the mission started,

Why pluto is no more a planet?

Just eight months after the probe was launched, the International Astronomical Union (IAU) officially decided that Pluto was no longer a planet — instead, it’d be categorized as a dwarf planet. The reasoning was partially based on Pluto’s tiny size, and partially on the fact that, in recent years, astronomers found several other similarly sized objects in the same region of space (called the Kuiper belt), including Eris, a dwarf planet that’s actually more massive than Pluto.

Slow Data Transmission…A decade old technology…

Because New Horizons is so far away, it takes about 4.5 hours for any data it sends back to reach Earth. And the signal is so faint that NASA has to use 200-foot-wide radio dishes (one each in Australia, California, and Spain) to pick it up.

This means an extremely low rate of data transmission: about 1 kilobit per second, more than 50 times slower than a 56k modem from the ’90s. So it takes more than 42 minutes for New Horizons to fully transmit an image that’s 1024 pixels wide.
