Chandrayaan Updates

- To Introduce with, Chandryaan was a two yr moon mission; was launched from Sriharikota on Oct 22^nd… it will draw a 3D map of  the moon, carrying out it’s chemical mapping and hunting for water/ice.

- India became the 5th member of the global moon club on saturday (8th Nov 08), with the craft entering the lunar orbit at 5.04 pm (IST)… Other four members are the US, Russia (former Soviet Union), Japan and China including the members of European Space Agency (ESA).

- The moon mission launcher, Dr. K. Kasturirangan said, the “Lunar Orbit Insertion” (LOI) was a nail-biting moment as the two objects – the moon and Chandrayaan – moving at a high speed had to have a successful rendezvous. At a certain point, the gravity of moon and that of Earth cancel out each other, making LOI very challenging.

- According to the ISRO officials, Chandrayaan’s liquid engine was fired for 817 seconds when the spacecraft passed at a distance of about 500 km from the moon to reduce its velocity to enable the lunar gravity to capture it around the moon. It’s speed was reduced to 366 m/s when it flew into the moon’s orbit.

- The signal to activate the liquid engine was flashed from the mission control room to chandrayaan that went via the deep space network at Byalalu.

- The spacecraft is now around the moon in an elliptical orbit that passes over its polar region. It takes about 11 hrs to go around the moon in this orbit.

- Further, the altitude of the spacecraft will be gradually reduced and the final orbit will be 100×100 km.

- Chandrayaan is carrying 11 instruments, of which six are from abroad – three from ESA, two from NASA, one from Bulgaria and five from India.

- Among the 11 scientific payloads, Bulgarian Experiment – Radom was activated on Oct 22 when the mission was launched. It took the Radiation Data which is already in place. Radom will assess the radiation Environment of the moon, which is expected to play a significant role when india decides on a manned lunar mission around 2020.

- Besides Radom, the indigenous Terrain Mapping Camera (Which will map the entire topography of the moon) and the hyper spectral imager (Which will provide information about minerals) have also been activated.

- The Remaining Experiments will be activated by Nov 20.

- It’s a significant feat; coz India’s moonshot was successful in the very first attempt – something that the US and Russia could not achieve!

 

A usual Saturday

Woke up at 12.15 pm (after12 hrs of sleep)… breakfast at 12:30 and lunch at 17:30 with evening tea!! And in between, did some long term and short term planning… Now will read some documents (on Research Methodologies)… and then A movie – Today “The last lear”.

 

Points For Me:

-         A lifetime Student cum philosopher!

-         Everyone has got his/her own importance in life.

-         Moving-on in an agreement with nature.

ACE Award-Q2 2008

Intranet says, “Good and appropriate reward & recognition does not happen by accident. It will not have the desired motivational effect and deliver business success, unless it is planned and managed well. The recognition should be event oriented and used for rewarding specific accomplishments, rather than reflecting sustained performance. ACE award was the first step in this direction.”

And Yes…  our Team won that ACE Award for the 2nd Quarter of 2008…  for performing exceptionally well in the BSNL projects. Our Honorable M.D. Mr. Mats Granryd presented the awards in Gurgaon office today… Thanks and Heartiest Congratulations to all of my seniors and colleagues for this special achievement. 

After all, Technology is a group activity.

 Again, I was not available there…

My Earth Explorer

Koool, so my native place Gaya is in Niger and Nigeria too… shows “My Earth Explorer”

Being a frequent traveller i needed an offline Globe badly…  just to get an idea about a particular location and for measuring distance between any two points on earth, etc … i got this tool here…

Happy Searching!!

ZFS: The last word in file systems

Here we go with the rhythm of the Title Song of Dhoom 2 (Nothing special about it, just liked its adventurous theme, haha!)… Let’s appreciate the tremendous work of the Sun Team led by Jeff Bonwick…  for creating ZFS (i.e Zettabyte File System)!!

I found it more interesting digging inside this file system. The main features include:

• High Storage capacity (Virtually Unlimited): As the world’s first 128-bit file system, ZFS offers 16 billion billion times the capacity of 32- or 64-bit systems.
• Provable data integrity: ZFS protects all data with 64-bit checksums that detect and correct silent data corruption.
• Near-Zero administration: ZFS automates and consolidates complicated storage administration concepts, reducing administrative overhead by 80 percent.
• Blazing performance: ZFS is based on a transactional object model that removes most of the traditional constraints on the order of issuing I/Os, which results in huge performance gains.

For other details and limitations, log on to wikipedia for ZFS.

 P.S.: “If you’re willing to take on the entire software stack, there’s a lot of innovation possible.” 

Just Rethinking of the architecture required!!

Fastest supercomputer for Earth Simulation!

Wow, a new Japanese supercomputer…. costing hundreds of millions of dollars was switched on this month…. and immediately outclassed its nearest rival. Before its launch, all of the top six supercomputers in the world were in the US. This new machine, called the Earth Simulator, is five times as fast as the best of these and is being used by the Japan Marine Science and Technology Centre to make predictions about the future of the Earth’s climate and its crust.
