India's historic lunar mission, Chandrayaan-3, has had an uneventful journey so far and if all goes well it should enter the lunar orbit on Saturday. A fortnight later, on August 23, ISRO hopes to attempt a soft landing near the south pole of the Moon with the Vikram lander carrying the Pragyaan rover in its womb. NDTV's Pallava Bagla explains the journey so far.
