kind of listener

When you assess yourself now,
what kind of listener are you?
  1. A deep careful listener
  2. A bored listener
  3. A selective listener
  4. A defensive listener
  5. An interruptive listener
  6. An insensitive listener

Do you want to know some tips how to become a good listener?

Follow the golden rule:

  • “Do unto others what you want others do unto you.”
  • Put yourself on the position of the one who is speaking to you.
  • Make an effort to listen to the person who is speaking by giving your full attention to the speaker.
  • Focus your mind to what he is trying to say and for the unspoken messages.
  • Watch for the non-verbal communication like tone of voice, hand gestures, facial expressions and other body movements.
  • Listen for the real meaning and not just for the literal words.
  • Finish listening first before you begin to speak for you to be sure that you understand what is being said
  • Think clearly what to react. Ask questions if you are not sure, to understand what the speaker is trying to convey.
  • Good listening requires practice and patience. But, if you hone this skill you’ll appreciate life more.

3 percent of the global population

  • 3 percent of the global population—more than 200 million people—live outside their country of birth
  • Uncounted millions more have moved, or been moved, within their home borders.
  • A great deal of this movement is forced, either by economic pressures or, increasingly, by damage to the environment or human conflict—both of which are exacerbated by rapid population growth.

Chandrayaan sends images of Apollo 15 landing

A camera on board India's maiden unmanned lunar mission Chandrayaan-1 has recorded images of the landing site of US spacecraft Apollo 15,

  • The Terrain mapper camera on board Chandrayaan-1 has sent the prints of landing site of Apollo 15
  • Tracks of the lunar rovers used by astronauts to travel on lunar surface
    "The images captured by hyper spectral camera fitted as a part of Chandrayaan-1 image payload has reconfirmed the veracity of Apollo 15 mission,"
  • The Chandrayaan-1 images have disproved the theory of conspiracy which had claimed that the Apollo 15 was a hoax, he said.
  • "Chandrayaan has managed to identify the landing site used by the Apollo 15 shuttle on the basis of the disturbances on the moon's surface
  • "Our images also show tracks left behind by the lunar rovers which were used by the astronauts to travel on the moon's surface
  • Since lunar dust is dark, the disturbances left behind by the spacecraft and the rovers are easily distinguishable. "The disturbed surface is bright
  • However, Chandrayaan's camera could not capture the images of footprint left behind by the first astronaut on moon, Neil Armstrong and Edwin Aldrin, because of its low resolution capability,
    that such an image is possible for a Lunar Reconnaissance Orbiter armed with high resolution camera launched into space by NASA.

Search operations

India’s biggest-ever air, land and satellite search operations to locate the Chief Minister, Dr Y.S. Rajasekhar Reddy, and others who went missing along with their helicopter in the dense Nallamala forests.

The helicopter was over the dense Nallamala jungles near the Srisailam dam, about 60 nautical miles from Hyderabad. It was carrying fuel for three hours.

Effort of Searching:

  1. The unprecedented effort included ultra-sophisticated remote sensing aircraft of Isro
  2. The IAF
  3. Private owned & Army helicopters
  4. Army personnel, 5,000 CRPF men and Andhra and Karnataka police forces.
  5. The elite anti-naxal Greyhound force, the anti-naxal central COBRA force
  6. The IAF later launched a Sukhoi Su-31MKI fighter aircraft equipped with the advanced Synthetic Aperture Radar (SAR) to track down the helicopter.
  7. The Indian Army launched about 300 hundred of its troops including two columns of specialised Ghatak forces
  8. The Army troops were equipped with hand-held thermal imagers and night-vision goggles
  9. The Indian Space Research Organisation flew two specially-equipped B-200 Beachcraft over the Nallamalla forests.
  10. The aircraft got 41 images, each covering 8 sq km.to the National Remote Sensing Agency, Of the 41 images, 21 were of no use, and no data could be picked up from the others.
  11. A thermal imaging aircraft that can pick out metal on the ground. This aircraft can be refuelled mid-air, meaning that it could operate for a long stretch of time.
  12. An additional Sukhoi fighter aircraft had been kept in readiness at Mumbai.
  13. The IAF despatched a Dornier and Avro aircraft to search for the missing chopper.

Chandrayan 1 Deployed 11 payloads

Chandrayan 1 Deployed 11 payloads

  • Five were designed and developed in India
  • Three by European Space Agency
  • Two were from the United States
  • One from Bulgaria.
  • The ESA's three payloads were the
  • Imaging x-ray spectrometer (C1XS)
  • The smart infrared spectrometer (SIR-2)
  • Sub kiloelectronvolt (keV) atom reflecting analyzer (SARA).

The US payloads were

  • The 6.5kg mini synthetic aperture radar (MiniSAR)
  • The moon mineralogy mapper (M3).

The Bulgarian payload

  • was the radiation dose monitor (RADOM).

The five Indian payloads were

  • The terrain mapping camera (TMC),
  • The hyper spectral imager (HySI)
  • The lunar laser ranging instrument (LLRI)
  • The high energy x-ray spectrometer (HEX)
  • The moon impact probe (MIP).

This mission is terminated abruptly after repeated attempts to restore communication link with the spacecraft by the space agency's telemetry, tracking and command network (Istrac) failed.

High temperatures led to faulty thermal protection.

India’s first Moon mission became casualty of unforeseen high temperatures that led to faulty thermal protection.

In May this year, the orbit of the spacecraft was raised to 200kms from 100 kms from the surface of the Moon. It was done for a better view and to enable further studies on orbit perturbations, gravitational field variation of the Moon and also enable imaging of the lunar surface with a wider swath.

the orbit was raised to escape the surface heat which was above 75 degrees Celsius. It was this that led to the failure of two star censors in July. These censors were responsible for the orientation of Chandrayaan and the scientists were operating the spacecraft using ingenious ways.

Unique in Indian Lunar mission

Most engineering goals have been fulfilled, but pious promises to deliver "good science" from the mission are still to be met.

This in itself was a big achievement since neither Russia nor America succeeded in their maiden attempts; and there were several failures even before they got anywhere near the Moon.
So did India ride on the shoulders of earlier successes?

Certainly not, since the know-how and technologies to go to the Moon are just not available for the asking. Each nation has to learn on its own. India experimented and did that with complete success.

The only other country to have managed a similar maiden feat was China - its mission Chang'e-1 in 2007 lasted 16 months in space,

The Indian mission survived for about 10 months in space; most other missions to the Moon have been much more short-lived.

Despite being dubbed by Isro as an "engineering success", the mission had a rough ride around the Moon.

  1. A fuel leak from the rocket almost aborted its lift-off.
  2. Within days of reaching the Moon, a power system failed, and a back-up system had to be activated.
  3. the spacecraft started overheating due to the intense heat on the Moon.
  4. Scientists say it was deft mission management that saved it from a total burnout.
  5. The mission the spacecraft lost its fine guidance system when the onboard "star sensor" packed up in the intense radiation around the Moon.
  6. The space agency lost all contact with Chandrayaan after a catastrophic failure - possibly in its power supply system.

SUCCESS

  • Every time an instrument on this 1,380kg robot gave way, mission controllers at Isro found an innovative solution to keep the mission alive.
  • The Indian mission was in certain respects much more challenging than the Chinese maiden lunar mission which was a simple national orbiter.
  • Chandrayaan-1 was literally a two-in-one mission, since the main satellite was to orbit at 100km above the Moon and then a tiny gadget the size of a computer monitor was to attempt a "landing" on the Moon's surface.
  • No nation to date had succeeded in both a lunar orbiter and an impactor at the first attempt.
  • Probe that crash-landed on the Moon also permanently placed India's flag on the lunar surface.
  • India became the fourth space bloc to have done this after Russia, America and the European Space Agency.
  • There are many other firsts to this mission.
  • In a highly un-Indian trait, the Indian space agency delivered the Moon mission with no cost or time overrun at $100m and within eight years of it first being suggested.
  • The spacecraft carried 11 different sophisticated instruments, one of the largest suites of experiments ever carried to the Moon.
  • The objective was to remotely map the resources of the Moon, prepare a three-dimensional atlas of it and look for water.
  • All instruments worked for about 10 months in the hostile lunar environment.
  • The chief scientist for Space Sciences at Esa, calls the Indian mission "the first multi-continent, multi-country lunar mission ever to be undertaken".
  • A little known fact is that India did not charge any money to fly these instruments 400,000km away: all got a free ride to the Moon, merely in exchange for sharing the scientific data.
  • Search for water Chandrayaan-1 was also the first and the most detailed search for water on the Moon using radars - to date, water has never been found.
  • A miniature American radar onboard the Chandrayaan peered into the Moon's deepest craters searching for "water ice".
  • The termination of the Moon mission will, however, not affect India's plans in space.
