Mars is so far away in fact that it takes radio signals quite a long time to get from the spacecraft back to Earth. During Curiosity EDL, this delay will be 13 minutes, 48 seconds, about mid-way between the minimum delay of around 4 minutes and the maximum of around 24 minutes.
Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): 1  Closest approach: 182 seconds, or just over 3 minutes. 2  Farthest approach: 1,342 seconds, or just over 22 minutes. 3  On average: 751 seconds, or just over 12.5 minutes.
