Thus for time-critical science, the IRM times need to be corrected by subtracting the light travel time from the spacecraft to the ground-station (at Weilheim in Germany apart special events requiring NASA DSN). For the transmission frequencies used, the vacuum light speed is appropriate. At apogee, this correction is more than a third of a second. There are no other known time delays.",
