TITUSVILLE, FL –  India’s first attempt to land a robotic probe on the Moon’s rugged surface apparently ended in failure today, Sept. 6, when mission scientists lost contact with the Vikram lander spacecraft in the final moments of its descent before the planned soft touchdown Friday afternoon, Sept 6 in a region near the lunar south pole – an area close to potential deposits of water ice and of high interest to scientists around the globe. 

Watch my live interview on BBC TV World News in its entirety - which aired at 9:06 p.m.  EDT Sept. 6 with later rebroadcasts, just  5 hours after the ambitious landing attempt by the ISRO  (Indian Space Research Organisation) ended with no signal from the 1470 kg Vikram spacecraft as part of the Chandrayaaan-2 mission.

The robotic landing had been scheduled for approximately 4:23 p.m. EDT at a landing site located at 70.9 degrees south latitude on the near side of the moon - much farther south and closer to the lunar south pole than ever attempted before.

The Vikram landing attempt was being broadcast live by ISRO as the Indian Prime minister Narendra Modi was watching and in attendance at the Chandrayaaan-2 Mission Control in Bengaluru, India, as the high drama situation quickly changed from excitement and anticipation to doom and gloom and sad faces.

Contact with the 4 legged spacecraft was lost at an altitude of only 2.1 kilometers after the four ‘rough braking phase’ thrusters had successfully fired at 4:07 p.m. ET to slow the descent from an initial velocity of 3600 mph following separation from the mothership Chandrayaaan-2 orbiter in lunar orbit shortly before 4 p.m. EDT to start a 15 minute powered descent that should have ended at nearly 0 mph for a successful touchdown.

Had the landing attempt succeeded India would have become only the fourth nation to land on Earth’s nearest neighbor – following the former Soviet Union, United States and China.

About an hour later the ISRO Chairman K. Sivan appeared and read this statement live:

“The Vikram lander descent was as planned, and normal performance was observed up to an altitude of 2.1 kilometers (1.3 miles). Subsequently, the communications from the lander to the ground station was lost. The data is being analyzed.”

No further details have been provided by ISRO. 

A mini rover named Pragyan with a mass of 27 kg (59-pounds) was also loaded on board the lander and would have descended to the surface a few hours after touchdown – had all gone well.


A NASA supplied laser retro reflector was loaded on board the Vikram moon lander – which measures 2.5 x 2.0 x 1.3 m (8.3 x 6.6 x 4 ft).

The lander mission was designed to last 14 days for 1 lunar day-. It was not built to withstand the frigid 14 day lunar night. 

Nevertheless India and its scientists and engineers are to be applauded for attempting this bold mission and Prime Minister Modi urged the team to work hard and “be courageous” as he also spoke to a large group on Indian students on had to watch the live proceedings.  

Modi also told everyone to beam with pride at Indias’ outstanding space program accomplishments conducted with home grown technology. 

“We came very close, but we will need to cover more ground in the times to come,” Modi said. “Every Indian is filled with a spirit of pride as well as confidence. We are proud of our space program and scientists. Their hard work and determination has ensured a better life, not only for our citizens, but also for other nations … India is suffering, but there will be many more opportunities to be proud and rejoice.

“When it comes to our space program, the best is yet to come. There are new frontiers to discover and new places to go … To our scientists, I want to say India is with you.”

Soft landing on the moon is not an easy task. In fact it’s an enormous engineering challenge and over half of all moon landing attempts have failed during the space age. 

A moon landing attempt by a private Israeli company failed earlier this year in April 2019 when the Beresheet probe crash landed.  Read our series of articles, enjoy our launch photos and watch my interviews with the I24 Israeli TV news channel.

China did successfully land a lunar probe for the second time earlier this year – on the lunar far side for the first time.

The mission cost approximately $140 million and continues with the  Chandrayaan-2 orbiter outfitted with eight state of the art instruments including high resolution cameras, spectrometers and radar to map the moon minerology and search for water ice in greater detail. 

Chandrayaan-2 is a follow up to Chandrayaaan-1 which was launched a decade ago in 2008 and detected the first evidence of water ice inside the moon permanently shadowed craters at the lunar poles.

ISRO says the Chandrayaaan-2 lunar orbital mission could last as long as 7 years - far beyond the original design goal of 1 year – an an altitude of around 62 miles (100 kilometers).

Chandrayaan-2 was launched on July 22, 2019 from India’s spaceport and achieved lunar orbit on Aug. 20. 

NASA aims to send the 1st woman and next man to land on the moon’s south pole on the Artemis 3 mission in 2024 – specifically to investigate the water ice in these permanently shadowed craters.
