Normal human beings, want to earn and earn a lot using their so called talents. They are proud that they possess such great abilities. In a way they exploit their own self by selling their talents.
But great saints differ from us in this very quality.Mahatma Pothana , who translated the Bhagavatham in Telugu from Vyasa Bhagavatham is not an exception to a great saint.
He said the above verse when he started writing the Bhavatham.
People think that he started this great task in search of huge wealth by dedicating this great litarature to the Kings. Pothana gave no chance for people to think about anything less than the dignity of his feelings towards this great task. To attain thy Ultimate Bliss , he shall complete this task ."Sri kaivalya padambu cherutaku" , is the pearl in the world of Bhakti Sagaram.

"Nenarun Nannya thikkandulu " as he said, The likes of Nannayya and Thikkana(great peots called Kavithrayam) are transalating the great kavya's like the Bharatha in to Telugu, I shall translate the Bhagavatha in to Telugu which will pull me out of this janana -marana cycle.

Space shuttle Discovery Lands Safely today

Space shuttle Discovery Lands Safely. This concludes the 15 days busy mission STS-120. Adding a new module to the ISS and repairing a torn solar array are the highlights of this mission.
Expedition 15/16 Flight Engineer Clay Anderson returned to Earth after 5 months, from the space station aboard shuttle mission STS-120.

This is one of the greatest padyam by Dhoorjati in Kalahstheeswara Shatakam.
In this Dhoorjati says "How can I describe you with the language skills I have ?..though I may try to describe your deeds and your greatness using the help of poetic skills , but that is not enough. "Hey ! poets , be ashemed of yourselves , as you areattempting an impossible task".....

Plasma Flares, Radio Silence what;s all about Re-entry?

The stage of a space shuttle during which the space shuttle leaves earth 's lower orbit and make a descent through the upper earth atomosphere is termed as "re-entry"....
This is the most dangerous and adventurous stage in the spaceshuttle descent.
A space craft to be stable in earth orbit , must have attained and maintained a critical velocity. This orbital velocity is nearly thirty times the speed of sound(mach) - around 13 kilometres per second. If the craft moves slower than this, it cannot stay in the orbit and makes a continuous descent to a lower orbit under the influence of gravity. Because the craft will now encounter atmospheric resistance, it will lose energy and fall under gravity.

In order to make a safe landing, a returning spacecraft has to lose nearly all of that orbital speed. The operation is basically a reversal of the launch phase, and this means that the returning craft must sink as much kinetic energy as the propulsion systems generated between lift-off and orbit.

  • What Happens ?

The mechanism of heating in re-entry phase is by friction that is viscous drag in the atmosphere. This is the predominant mechanism only at lower altitudes, as air density increases.
A re-entering craft develops a very energetic pressure wave at its leading edges/surfaces. The energy density is sufficient to cause atmospheric molecules to dissociate, and their component atoms to become ionized. The vehicle thus descends in a superheated shroud of incandescent plasma.
Plasma, known as the fourth state of matter, does not conform to the gas laws of conventional thermodynamics, although it does share one familiar property - a proportionality between pressure and temperature in a contained system. The formation of the pressure wave, therefore, also creates extreme temperatures. The plasma stream is electrostatically-charged too, and so it concentrates at acute surface contours, a behaviour related to the ground-level phenomenon of corona discharge. The resultant effect is particularly intense local heating at the airframe's leading edges.

  • Phases , de-orbit burn till te final Touchdown

Flying BrickYard

About seventy minutes before touchdown, thrusters flip the orbiter(craft) right over about its pitch axis, so that craft's attitude is nose-first and belly-up. There is no frictional shear on the airframe ath this time. The main engines are then fired for about twenty seconds. The thrusters fire again in a different configuration, rotating the craft on its yaw axis. It emerges from this sequence in the descent attitude, nose forward and slightly upward, and belly facing downward. This belly is covered in the ceramic tiles . The speed of the vehicle is now below the critical orbital velocity, and so it starts to come down.

Entry Interface

Entry Interface begins at around thirty-five minutes before touchdown and at an altitude of around 120 km, the orbiter enters a discernable atmosphere. Though still extremely rarefied (containing little oxygen), there is now enough external matter to undergo ionisation, and the plasma flare begins to form. The linear distance to the landing site is about 8,000 km,. From this point, the angle of attack is critical, and is maintained at 40 degrees by automatic and continuous thruster trims. Any shallower, and the orbiter will experience excessive lift and overfly its destination. Any steeper, it will burn up.
At an altitude of 85 km, the flight surfaces of the orbiter becomes usable. Under automatic control, a series of four S-bend turns is now performed, with the craft banking through 80 degrees at the fullest extent of the roll. The object is to lose speed more quickly.

It's now twenty minutes to touchdown, and the plasma cloud is at its most intense. This is the hottest phase of re-entry, and in terms of the integrity of the structure the most dangerous.

Unlike the Apollo missions, the shuttle never normally endures a period of radio silence. The enclosure of the vehicle by plasma is never complete : there is always a window at the tail through which a signal can be beamed out. These days there are satellites capable of receiving this too, and so a continuous transmission returns to earth.

Final Descent

Ten minutes before touchdown, the orbiter is 40 km high in altitude, and its speed is still nearly 10,000 kph (Mach 8). The highest skin temperature, on the underside of the wings close to the leading edges, is around 1,600°C. Plasma flaring has now ceased, and has now been replaced by reactive hypersonic flow. Drag on the craft increases greatly, and deceleration takes place more rapidly.

The pilot will now be ready to take over control, and normally does so about seven minutes out, as the speed drops below 4,000 kph and into a stable supersonic regime. For the first time, the vehicle is pitched forward so that the nose is pointing downwards. Conventional flight surfaces now become effective, such as the air brakes which can be applied through the fantail configuration of the orbiter's rudder.

The speed at touchdown is 350 kph. The rear wheels come down first, and a chute is deployed to slowdown the vehicle - it has no means through which to exert reverse thrust. The orbiter's very robust wheel-brakes are progressively applied. As the speed falls to about 150 kph, the nose-wheel touches down and full braking is employed. The chute is jettisoned just before the craft rolls to a complete stop, somewhat more than two kilometres from its point of touchdown.

Hello World!!!

I created a blog site , so what's the big deal? innumerable number of blogs gets createdevery hour....
what's all about this blog? well, the name should speak , its Truth , Knowledge and Infinity. This is a Mahavakya from the Taitariya -- "SaTyam , JNAnam, AnanTham Brahma... Yo VedaNihiTam GuhaYam"
I am not sure th, how will I use this t o let out my dooughrment feelings so far....
