Especially impressive when taken into account that ISRO couldn't achieve the soft-landing with Chandrayaan-2 four years ago. One of the big things they changed with this lander compared to Chandrayaan-2 was to increase the landing zone from 500mx500m to 4000mx4000m and adding more sensors and cameras to help the computer find a good landing site. For those who didn't watch live, there was another hover phase (0 m/s d…
The whole hover and look around thing was super impressive to me. That choice to spend mass on fuel for such maneuvers vs science instruments seems to always go to science in NASA debates and we end up with "either it will land here, or it will die." :-) Great outcome and I look forward to the pictures sent back by the rover!
Most missions have several different scientific systems on board. If any one fails well the others still make the mission a partial success. If the landing system fails they all become a failure.
