We send a lot of rovers to Mars, as interesting as the planet could possibly be. But why are we not putting satellite grids around planets that could transmit superficial probe data at the very least? That seems to me like a much more interesting project.

    $\begingroup$ Most other planets or other destinations have 0 or at most 1 spacecraft around them so the need for orbiters to act as relay satellites as Mars Odyssey does for the Martian rovers isn't there. $\endgroup$ – astrosnapper Mar 13 '20 at 21:40

    $\begingroup$ This seems that it would be better suited to the space exploration site. $\endgroup$ – James K Mar 13 '20 at 22:26
  • $\begingroup$ Lol, so I guess we can just forget this question. But I did mean "grids". $\endgroup$ – dante5772 Mar 13 '20 at 23:54

    $\begingroup$ The answer to "Why are we not putting satellite grids around planets..." is that money is not infinite and what there is is (supposedly) being spent in the most effective way possible. $\endgroup$ – uhoh Mar 14 '20 at 16:38

    $\begingroup$ I'm voting to close this question as off-topic because it is not on-topic in Astronomy SE as defined in the help center. However questions about how space exploration missions are planned, evaluated, funded and carried out are on topic in Space Exploration SE. $\endgroup$ – uhoh Mar 14 '20 at 16:40
