India's moon lander suffered a hard landing but is unbroken, the country's space agency said on Monday.

Landing on the moon and exploring its surface was the main objective of India's US$140-million Chandrayaan-2 mission, but communication was lost with the lander, dubbed Vikram, in the final moments on early Saturday when it was just 2.1 km above its supposed parking spot.

The failed mission caused much dismay across the nation which had hoped to create history with the first landing by any country on the unexplored lunar South Pole.

"The lander is there (on the lunar surface) as a single piece, not broken into pieces. It's in a tilted position," PTI quoted an official of the Indian Space Research Organisation (Isro) as saying.

"We are making an all-out effort to see whether communication can be re-established with the lander," said the unnamed official who worked on the venture.

Only the US, Russia and China have accomplished successful moon landings.

Israel attempted a lunar mission in April this year but its spacecraft Beresheet crashed on the moon. The Chandrayaan-2 mission was made up of an orbiter, the lander and a rover.

The rover was to roll out of the lander to carry out exploration if the landing had been successful. - Bernama
