INSUBCONTINENT EXCLUSIVE:
soft-landing on August 23 with the ramp that allowed the rover to roll out.The photographs taken at at 7.3am and 11am Wednesday using the
The second batch (taken at 11am) of photos Isro released was taken from just 15m from the lander
The Pragyan navigation cameras, the ones that guide the rover, were developed in a quiet lab called LEOS in Bengaluru.The Laboratory for
Electro-Optics Systems or LEOS had first developed these cameras as early as 2012 as part of preparations for Chandrayaan-2
And the target set for me was to make light-weight cameras that could withstand lunar radiation and extreme temperatures
Each of the two cameras weigh only 125 grams
miniaturised digital cameras, Selvaraj said, use multi-element lenses and their image quality was verified through a host of tests on the
conditions, these can perform for a really long time
The material and processes used also allow it to survive extremely low temperatures
allowing it to navigate on the lunar surface, while also sending in pictures
For every path planning, data from these navigation cameras need to be downloaded to ground where a digital elevation model (DEM) is
Then, the ground and mechanisms teams decide which path is best for Pragyan and uplink the command for the rover to follow.The images taken
by the rover further reiterate how smooth the landing was on August 23 and how firm Vikram is on Moon
