8 months ago, The final stage of the mars science laboratory launch vehicle put the craft to 13000 miles per hour ready for its journey to mars. The Mars Science Laboratory or Curiosity Rover is a massive interplanetary payload
8 and half months,this journey will end space craft enter the mars atmosphere
Still 13000 miles per hours and that moment the craft will lose contact with us
7minutes later it will be gone 0 mile per hour engineer called “the 7 minutes to terror”
First atmosphere heat as the shield 600 degree Celsius, slow the craft down, 1000 miles per hour
That job is done by the parachute, the largest supersonic parachute, 100 lb, 65000 lb
Mar atmosphere is so thin, the parachute is not enough to land safely
(E gasted?) of third stage is necessary, Both vertical and horizontal speed
The craft now use the radar and camera not just see how high it is, but spot landing area so it can hit the fine area
