Wish You All A Happy & Prosperous Onam


ഹൃദയം നിറഞ്ഞ ഓണാശംസകള്‍ 

 by G. Binukumar, Nimr, Sultanate of Oman


President Pranab Mukherjee in his message said, "On the joyous occasion of Onam, I offer my warm felicitations and heartiest greetings to all my brothers and sisters belonging to Kerala."

He said the festival brings out the rich cultural heritage of Kerala in its best form and spirit.

"May this harvest festival instill in us the spirit of national integration and inspire us to work for further development of our country" Mukherjee said.


Vice President M Hamid Ansari said Onam plays an important role in uniting people.
He wished that the festival "may usher in peace, prosperity and happiness in the society and contribute in the nation's progress"


Onam is a Hindu festival, celebrated by the people of Kerala in India. Also known as Vamana Jayanti, it solemnizes the Vamana avatar of Vishnu and the homecoming

of the legendary Emperor Mahabali. The festival falls in the month of Chingam and lasts for ten days. 

The festival is acknowledged for its colorful and vibrant celebrations like Onnapotan  (a Kerela art form), Puli Kali (Masked leopard dance), intricate flower carpets and the like. Besides these festivities, prayers are being offered in Hindu temples by Hindus and the non-Hindus are not allowed to enter the sacred temples. Onam is a venerated feast for Mahabali, a revered figure since the primordial times.

The celebrations of Onam begin on the Atham day, ten days before Thiruvonam.  The ten respective days of festivity start with Atham, followed by Chithira that makes way for Chodi, in succession comes Vishakam subsequently followed by Anizham, Thriketa, Moolam, Pooradam, Uthradom and finally comes, Thiruvonam, also known as “Second Onam”. Colors, flowers, new clothes, performing various folk-dance and other cultural activities become the hallmark of Onam. It is the picturesque fervor that adds to the dramatic element in Onam.

It is amazing to see the legacy of Onam going in the modern times. It’s a ritual that marks the succession of the Keralite traditions and customs. People who cannot make it to the festival send their loved ones greeting cards, online and through mails. Greeting cards in Onam keeps the spirit of the festival alive in people near or far. The festival of color and flowers has gained immense popularity. Thus, the ongoing revelry and rejoice!

Curiosity Lands on Mars August 6, 2012 An unprecedented feat of technology

Monday, August 6, 2012 - 0 Comments


Curiosity, a Mars rover, in Gale Crater on August 6, 2012 at 05:14:39 UTC. American President Obama calls Curiosity landing an 'unprecedented feat of technology".

 Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed Curiosity, a Mars rover, in Gale Crater on August 6, 2012 at 05:14:39 UTC. Coverage as it happened as Nasa lands Curiosity, a metric-tonne rover, on Mars, the first time the US space agency has attempted to land a probe of that size on Mars. Touchdown took place just after 6.30am Monday morning.

First images from the Curiosity rover which landed on Mars


One of the first images from the Curiosity rover which landed on Mars the evening of August 5, 2012, with camera dust cover in place, shows the wheel of the rover after it successfully landed on Mars. 

Gale Crater is the MSL landing site. Within Gale Crater is a mountain, named Aeolis Mons (i.e. "Mount Sharp"), of layered rocks, rising about 5.5 km (18,000 ft) above the crater floor, that Curiosity will investigate. The landing site is a smooth region called Aeolis Palus inside the crater in front of the mountain. The landing site is elliptical, 20 by 7 km (12 by 4.3 mi). Gale Crater's diameter is 154 km (96 mi).

Landing a large mass on Mars is particularly challenging as the atmosphere is too thin for parachutes and aerobraking alone to be effective while remaining thick enough to create stability problems when decelerating with rockets.Although some previous missions have used airbags to cushion the shock of landing, Curiosity rover is too heavy for this to be an option. Instead, Curiosity set down on the Martian surface using a new high-precision entry, descent, and landing (EDL) system which placed it within a 20 by 7 km (12 by 4.3 mi) landing ellipse, in contrast to the 150 by 20 km (93 by 12 mi) landing ellipse of the landing systems used by the Mars Exploration Rovers. The landing sequence alone requires six vehicle configurations, 76 pyrotechnic devices, the largest supersonic parachute ever built, and more than 500,000 lines of code, in a final sequence that was dubbed "seven minutes of terror" by NASA. The spacecraft employed several systems in a precise order, with the entry, descent and landing sequence broken down into four parts.

The nylon bridle will break free and the mother-ship will speed away to a safe distance where it will eventually run out of fuel and fall to the surface. Meanwhile, Curiosity will hopefully have landed wheels down with no obstruction, ready to roam and make some extraordinary scientific discoveries.


Launching of Curiosity

MSL was launched from Cape Canaveral Air Force Station Space Launch Complex 41 on November 26, 2011, at 10:02:00.0 EST (15:02:00.0 UTC) via the Atlas V 541 provided by United Launch Alliance. This two stage rocket includes a 3.8 m (12 ft) Common Core Booster (CCB) powered by a single RD-180 engine, four solid rocket boosters (SRB), and one Centaur III with a 5.4 m (18 ft) diameter payload fairing. The NASA Launch Services Program coordinated the launch via the NASA Launch Services (NLS) I Contract. This vehicle is capable of launching up to 7,982 kg (17,600 lb) to geostationary transfer orbit. The Atlas V has also been used to launch the Mars Reconnaissance Orbiter and the New Horizons probe. The first and second stage along with the solid rocket motors were stacked on October 9, 2011, near the launch pad. The fairing containing MSL was transported to the launch pad on November 3, 2011.

Curiosity has been careering through space for almost one year since its launch from Cape Canaveral Air Force Station, in Florida, at 10.02am, November 26 last year. Since then, the spacecraft housing Curiosity – the Mars Science Laboratory spacecraft (MSL) – has had a reasonably problem-free journey travelling the 127 million miles from Earth to Mars.
Breaking this down specifically, there have been 254 "cruise days" in the journey and 45 "approach days" when the probe was preparing for entry.
