Tianwen 1 will carry out its 2nd orbital correction in September to ensure that it travels in the preset orbit, according to CASC. As the Mars probe travels further from Earth, the communication delay is increasing. Currently, the delay is about 30 seconds, and when the probe approaches Mars, the one-way time lag can be more than 10 minutes.
The probe carried out its first orbital correction on 2 August. During its flight to Mars, the probe will conduct 4 orbital corrections and a deep-space manoeuvre, according to a source from the CASC.
