India Loses Contact With Chandrayaan-2 Mission During Moon Landing Attempt

Source: New York Times

India’s attempt to land a robotic spacecraft near the moon’s South Pole on Saturday appeared to end in failure.

The initial parts of the descent, as engines fired to slow it down from orbit, went smoothly. But less than two miles above the surface, the trajectory diverged from the planned path. The mission control room fell silent as communications from the lander were lost. A member of the staff was seen patting the back of K. Sivan, the director of India’s space program.

He later announced that the spacecraft was operating as expected until an altitude of 2.1 kilometers, or 1.3 miles. “The data is being analyzed,” he said.

The partial failure of the Chandrayaan-2 mission — an orbiter remains in operation — would delay the country’s bid to join an elite club of nations that have landed in one piece on the moon’s surface.

4. In fact we saw Vikram fall to 335 meters altitude

on the data display, when it froze. The vertical velocity was shown as 59 meters per second.

The 'fine braking' phase appeared to have succesfully started, but then failed.




The technicians also appeared frozen in place for minutes, until Modi demonstrated his leadership talents...
