In my opinion, NASA has never sent any probe to Mars. It's another hoax like the false moon landing.
To land Phoenix probe on Mars they used a 12 meters parachute (diameter). That probe weighed 350 kg.
To land Curiosity probe they have used a 15 meters parachute. This probe weighs 900 kg.
Phoenix probe landing: SEVEN MINUTES OF TERROR
Curiosity probe landing: SEVEN MINUTES OF TERROR
Mars gravity: 38% of Earth's.
Mars atmosphere density: 1 % of Earth's.
How is it possible to slow down 342 kg (900 x 38 % = 5 men's weight) on Mars with 15 meters parachute if atmosphere density is 1 % of Earth's.
On the Earth you need: 5 men x 7 sq m (parachute 3 meters diameter) = 35 sq m = about 6 meters diameter.
Suppose to slow down Curiosity's velocity at 70%. Let's make the calculation (density 1%): 35 sq m x 70 = 2450 sq m : 3.14 = 780 Square root of 780
= 28 meters radius = 56 meters diameter
You need a 56 meters diameter parachute to slow down Curiosity at 70 % of its velocity in the rarefied atmosphere of Mars
