Coms on Mars

Communications is going to be a big issue for the human mission to Mars.

With the Starships able to accommodate maybe an 8 metre diameter dish, and taken along powerful transmitters, what sort of quality broadcasts could be undertaken?

Given NASA has its global network of huge receivers that can pick up very tiny radio signals, I am assuming we are going to see a huge improvement in coms.

Could we see live TV transmission from Mars? TV broadcasters wishing to "interview" the Mars pioneers would have to prepare their questions beforehand and then read them out 12 mins or whatever before they were going to be heard on Mars. Would take some co-ordination but could be done - people on Mars would have to have a countdown to show how long they have to answer.

Presumably HD images and video could be relayed from Mars at intervals.

And of course the pioneers could bring back many hours of HD video.

no ionosphere so coms only up and down while over head to orbiting satelites

Re: Coms on Mars

I'm assuming Space X can do direct coms to Earth from the Mars surface with a powerful transmitter and receiver. I doubt transmisson via satellite will be required because they are quite small transmitters in any case.

Re: Coms on Mars

China or Musk or Europe or Japan or someone should put a bunch of micro-sats around Mars, see 'Project West Ford' for how silly things got on Earth

Re: Coms on Mars

There to it than power as a transmitter on the surface must wait for direct line to open up as the planet blocks the signals.
