Yep. We could cover Mar's sky with something similar to SpaceX's Starlink (high availability from any location on Mars) but with large data buffers and transmission systems that can pump the goods all the back to Earth.
Hardware has to withstand the elements, including the radiation. On Earth we have the atmosphere to absorb a substantial amount compared to on Mars and the Moon.
The problem with newer sensors and such is that they're not designed to handle the stress of going into space as well withstanding the greatly increased radiation exposure on Mars and the Moon. The missions to send stuff up into space is already expensive and so you'll have to reduce the chances of the gear you're sending up of failing. Unless you can afford to keep making trips to Mars until you get something there that works and then stays working long enough to do viable work.
