Chandrayaan 3 moon landing: Pragyan rover to roll out in next few hours after lunar dust settles down

A historic moment is about to unfold as the Pragyan rover, carefully installed within the Vikram lander, is poised to embark on its journey of exploration and discovery on the Moon's surface. 

Here is a 5-point cheat sheet for this big story:

-- Lander Vikram's final touchdown speed was well within its safe limits. Four engines ran initially. Two of them were shut down later, so the touchdown on the lunar surface was powered by two engines.

-- Lander Vikram kicked up a large cloud of Moon dust when it landed. The dust will not settle down anytime soon due to the extremely weak gravitational force the Moon exerts but will scatter away on its own momentum.

-- The rover Pragyan will emerge from the lander three-and-a-half hours after lander Vikram touched down on the lunar surface near the Moon's South Pole. India is the first country to land a spacecraft near the lunar South Pole.

-- The Indian Space Research Organisation (ISRO) did not want the fine Moon dust to coat the cameras and other sensitive instruments, so it decided to wait for over three hours to ensure the dust moved away from the lander Vikram.

-- The rover Pragyan will first extend its solar arrays and roll out with a wire connected to the lander Vikram. The wire will be snapped once the rover is stable on the lunar surface. It will then start its scientific mission.
