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.
Radio signals that carry the data travel at the speed of light which is about 300,000 kilometers per second. At this speed, the signals can reach Earth in as little as 4 minutes (78 million km), or can take as long as 21 minutes (377 million km). Engineers refer to this length of time as the one-way light time..urveyor will take 309 days to reach Mars. In theory, the ideal transit time is 259 days. However, the journey can take anywhere between seven to 10 months depending on type of trajectory chosen and the precise locations of Earth and Mars at the time of launch.
