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.
When Rosetta phoned home to the European Space Agencyâs mission control in Darmstadt, Germany today, it took 28 minutes for the signal to reach Earth, traveling 317,520,679 miles. The spacecraft is scheduled to land at 8:30 a.m. ET, and by 11 a.m. ET we will know if it hit its target and is functioning.
