Intercommmunication between crewed space missions in all planets of solar system.

As we know Human Communication taking place between Man in space, Man on Moon, Man on Mars (Future exploration) with Human beings on Earth planet where we are living with the help of control stations controlled by space agencies from different countries.

Is this also very much possible as per the scenario/s given below with advancement in space science and technology?


Human beings in one planet communication with Human beings in other planet excluding planet earth.

Of course, the exploration of crewed missions takes place taking into account whether life exists on other planets than planet earth, mars (possibility).

Just an assumption, that if life exists on other planets Or even if Life do not exists on other planets,what can be done in case a Human being on Mars planet would like to communicate with Human being on say Jupiter planet?

Examples :

Mars - Jupiter

Mars - Uranus

Mars - Saturn

Mars - Venus

Mars - Pluto

Mars - Mercury

Mars - Neptune

-------------------------------

Jupiter - Mars

Jupiter - Uranus

Jupiter - Venus

Jupiter - Mercury

Jupiter - Pluto

Jupiter - Neptune

Jupiter - Saturn

and all other permutations & combinations of one planet communication with other seven planets excluding earth.

So no direct communication between two planets but only possible with planet earth as interpreter or translator?

Example:

Mars & Jupiter would like to communicate with each other.

Mars - Hello - Earth

Earth - Hello - Jupiter

Jupiter - Hi - Earth

Earth - Hi - Mars

So no direct communication possible of Hello, Hi between Mars & Jupiter planets possible?

To simplify my question, in case Humans land on both planets Mars & Jupiter via earth planet, can they directly communicate with each other without taking assistance of Humans on planet Earth?.

Assumptions or even could taken as a fiction movie for life existing on both planets mars & jupiter as well as in all other planets of solar system for the above scenarios with permutations & combinations.

Interplanetary telecommunications setup in solar system.

If the astronauts visit the planets Jupiter, Venus, Saturn, Mercury, Neptune, Uranus, Pluto, will they be able to survive for specific time period in terms of days, weeks, months, years theoretically according to space & astronomy study?

Voyager 1 is over 14 billion miles away from earth but scientist can still communicate with it. It does however, take 42 hours for radiowaves to make the round trip. Survival on many of the planets is highly unlikely for humans.

Click to expand...

Direct radio communication between any two planets would be possible without involving Earth.

It would need satellite relays at a minimum, for guaranteed communication while the ground-based end rotated away from line-of-site to other destinations for half the planet "day" period.

Also, relaying via another planet or dedicated relay link when two endpoints were at opposite sides of the Sun; as well as a direct block if in the path, it's a fairly strong source of radio interference.

Nothing can get around the delays involved due to speed of light propagation of radio signals.

Trivia - if you are interested, there is an old SciFi book based around the exact concept you are asking about; "Venus Equilateral" by George O. Smith.
