BENGALURU/MUMBAI--India lost contact with a spacecraft it was trying to land on the moon on Saturday, its space agency said, in a setback for the nation's ambitious plans to become the first country to probe the unexplored lunar south pole.

  The lander of the Chandrayaan-2 moon mission was attempting a "soft," or controlled, landing near the south pole of the moon where scientists believe there could be water ice. Communication was lost just as it was about to touch down.
  "Data is being analysed," K Sivan, chairman of the Indian Space Research Organisation (ISRO), told distraught scientists at the agency's tracking centre in Bengaluru.
  The Indian designed spacecraft, which had been orbiting the moon, began descending to the lunar surface at about 2007 GMT but scientists lost contact with it during the penultimate stage of the descent. A live broadcast from ISRO, India's equivalent of NASA, showed scientists grow tense and the floor fall silent as the control station struggled to get a signal from the lander.
  "There are ups and downs in life ... What you have accomplished is no small achievement," Prime Minister Narendra Modi, who was present at the ISRO centre, told scientists after being briefed by Sivan.
  ISRO has not commented further, but Modi hinted in an address to the nation that the lander might have travelled at a higher-than-expected speed and crash landed on the moon. "If historians some day write about today's incident, they will certainly say that inspired by our romantic description of the moon throughout life, Chandrayaan, in the last leg of the journey, rushed to embrace the moon," he said.
  "I can proudly say that the effort was worth it and so was the journey," Modi added.
  In an emotional moment broadcast on TV channels, Modi embraced and consoled a visibly heart-broken Sivan. "We are full of confidence that when it comes to our space programme, the best is yet to come," Modi said.
  Sivan had earlier described the final moments of the landing mission as "15 minutes of terror," due to the complexities involved with lunar gravity, terrain and dust. Only the United States, Russia and China have landed on the moon. Beijing's Chang'e-4 probe touched down on the far side this year, while Israel made an unsuccessful attempt to land its Beresheet spacecraft on the moon in April.
