# Chandrayaan-2 orbiter and lander communications with Earth (IDSN)

In the Seeker video India Could Be the First to Land on the Moon’s South Pole a bit after 04:20 the narrator says:

Okay, well right about now you’re probably wondering how will we be getting any of this information back to us? Well this is where our Vikram lander comes in. Vikram will be in communication with Pragyan, and anything the rover finds will be reported back to Earth via the Indian Deep Space Network.

The orbiter will operate independently with the IDSN, so the team can contact it no matter where it is in its orbit.

I don't quite understand all of this. It sounds like the rover communicates with the lander, and the lander communicates with Earth via the IDSN, without using the orbiter to cache or link.

The orbiter also communicates with IDSN independently, but what does the following phrase mean?

...no matter where it is in its orbit.

If "it" is the orbiter then it seems that the orbiter is in an Earth-synchronous lunar orbit, and I don't think those exist naturally since there's practically no J2.

Perhaps the sentence should be "so the team can contact the lander no matter where the orbiter is in its orbit" instead?

• @WilliamR.Ebenezer thanks for that, I must have missed the "mars" part ;-) – uhoh Jul 15 at 7:00
• I have to say, it is now confusing. Now, I'm talking about visibility from the South Pole to IDSN. Might come up with AzEl graph and then follow up with an explainer. But its definitely not a lander-orbit-IDSN primary link, the X-band transmitter size suggests a direct link, so there are two alternatives as far as I can confirm from literature. – ASRI_306 Aug 21 at 15:17
