Hours after touchdown, rover Pragyaan will roll out from inside the lander to carry out intense probe of the moon soil with its two payloads.
The crucial landing of ‘Vikram’, Chandrayaan-2’s moon lander, will be carried out by at least eight onboard equipment in a coordinated manner.
‘Vikram’ with rover ‘Pragyaan’ housed inside is scheduled for a powered-descent between 1 am and 2 am on September 7, followed by its touchdown between 1.30 am and 2.30 am. Ahead of the proposed touchdown in the early hours of Saturday, the Isroexplained through a video how it will take place.
The space agency explained that the machine will be fitted with at least three cameras, Lander Position Detection Camera (LPDC), Lander Horizontal Velocity Camera (LHVC) and Lander Hazardous Detection and Avoidance Camera (LHDAC), to ensure its soft landing on the lunar surface. There will be two KA Band Altimeter-1 and KA Band Altimeter-2.
The KA Band stands for Kurtz-above band, which is part of the Kurtz (K) band in the microwave band of the electromagnetic spectrum. There will be a Laser Altimeter (LASA), an instrument that is used to learn about the topography, or the shape of the surface of a planet. It will operate through the orbitor revolving around the moon above the lander….
