Pakistan whines over ISRO's 100th satellite launch but India is already watching over it

  Pakistan whines over ISRO's 100th satellite launch but India is already watching over it Pakistan whines over ISRO's 100th satellite launch but India is already watching over itOnce bitten twice shy. This is what led India to have an eye in the sky. The Kargil misadventure by Pakistan convinced India that Islamabad could no longer be left unwatched. And, now Pakistan complains that India is keeping an eye over it, this time from the heavens.

New Delhi: Indian Space Research Organisation is all set to launch the “Cartosat-2 Series” satellite riding on PSLV rocket this morning. This will be the fourth time the novel method would be used by the ISRO for placing satellites in multiple orbits in a single flight.

Space agency ISRO this morning successfully sent up a rocket carrying India's 100th satellite along with 30 others, four months after failed launch. The Polar Satellite Launch Vehicle or PSLV lifted off at 9.29 am from Sriharikota in Andhra Pradesh and a key component that had failed in August worked this time, causing scientists to gasp in relief at having crossed a major hurdle. The lift-off was postponed by a minute because of fear of collision with space debris. The last launch of IRNSS-1H - India's first privately built satellite -- on August 31 last year had failed because of a freak accident. This is the 42nd flight of the PSLV.

"Let's look at facts": A Raja challenges former CAG Vinod Rai to debate on 2G spectrum allocation

  "Let's look at facts": A Raja challenges former CAG Vinod Rai to debate on 2G spectrum allocation"Vinod Rai is like a cat that closes its eyes to declare the world is dark. I challenge him via your channel. Come have a debate. Let's look at facts. The entire CAG agreed there was no loss so why did Vinod Rai say this motivated thing," Mr Raja said to NDTV on Thursday, a day before his book "2G Saga Unfolds" is released.

Among is the satellites that the ISRO 's PSLV is carrying is India's 100 th satellite , Cartosat . The launch will be said to be successful only after all the 31 satellites have been put into orbit.

The launch came four months after the ISRO failed to put a satellite in orbit following a mission failure . A PSLV C-12 blasts off from Satish Dhawan space centre at Sriharikota, April 20, 2009. HIGHLIGHTS. ISRO launched its 100 th satellite today.

New Delhi:

  1. The 30 other satellites include two other satellites from India and 28 satellites from six countries -- Canada, Finland, France, Korea, the United Kingdom and the United States
  2. Scientists said the mission is a unique one, since the satellites will be launched in two orbits. Thirty of the satellites will be launched in an orbit 550 km about, and one 359-km above the Earth.
  3. This will be done through what scientists call the "multiple burn technology" under which the rocket's engine is switched off and then switched on to control its height.
  4. The whole process of placing the satellites in two orbits will take 2 hours 21 minutes -- the longest so far. The 28-hour countdown for the launch of the PSLV started at 5.29 am on Thursday.
  5. The 710-kg earth observation satellite the PSLV is carrying the third in the Cartosat 2 series. The last satellite of the series had been launched successfully in June 2016.
  6. ISRO had brushed off speculations of sabotage after the last satellite launch failure. Scientists said a tiny but vital equipment of the rocket had failed, due to which its protective heat shield could not be separated.
  7. The heat shield of a satellite is meant to protect it from the heat generated by the friction against atmosphere during take-off. 
  8. The launch became necessary after three atomic clocks of one satellite started malfunctioning. Atomic clocks provide navigational data, and they are crucial for a Global positioning system.
  9. NAViC, a system of seven satellites, powers India's powerful homegrown Global Positioning System.
  10. ISRO's workhorse PSLV rocket weighs nearly 320 tonnes and stands up to 44.4 meters, equivalent to a 15-storey building.
