Chandrayaan-2 faces tough challenges: Isro

MUMBAI: In its latest build up towards the much-awaited Chandrayaan-2 launch between July 9 and 16, Isro, on Monday, said it will face some tough challenges while executing a soft landing of its rover, Vikram, on the moon’s south pole.
Isro said the first challenge relates to maintaining the accuracy of the trajectory of the spacecraft, meaning Chandrayaan-2 must follow the designated path to the moon since the distance is 3,844 lakh kms.
The second challenge relates to deep space communication since radio signals are weak with heavy background noise which needs to be picked up by large antennas. The third challenge—the ‘trans lunar injection and lunar capture’, which means getting into the moon’s sphere of influence—will be a critical manoeuvre as it has to be an extremely precise and accurate calculation.
