I feel like this is going in the wrong direction. This suggestion is just off.
Like, the reward for something in the game shouldn't be less gameplay. If exploration isn't exciting, the problem is that **exploration isn't exciting**.
If you want to auto survey, you might as well just take exploration out of the game entirely. Isn't the right approach to, you know, just make exploration more fun?
The game is all about space combat. How about more combats out in distant sectors? More interesting encounters in distant systems, and better loot as a reward?
That might come at a later point, regarding the suggestions you have made. And yes, explorations is super dull at the moment as I do not find it exciting to go to multiple planets and spam press the G key 99% of the time. But to counter your idea that this is making the game shorter, look at the arms dealers that you can find in bars randomly that sell you every ship and blueprint at a higher price. Basically the player shortcuts the game by a lot this way as well. The idea is that you are not forced to use these vendors, the same as you are not forced to use the Exploration team if you want to do it by yourself. This just adds an alternative that players that have plaid the game multiple times, avoid going through all the exploration grinding just to find a place to set up colonies. After that, if you wish to go and explore certain places in search for special treasures or more extreme fights, that is an entirely different thing.
Also, the Exploration team does not do the fighting in the sector for you, so it would not eliminate bounties or Remnants, just collect the items and scan the planets (in sectors that are not dangerous to them). Also, you can split exploration into sending them into scanning the peaceful sectors for you (they determine which ones are those when they get there) while you could go and clean up the ones that they avoided. Exploration for the player is not being taken out of the game this way, it just makes it less of a click fest and more about you taking risks out there.
And again, sending the Team to do the heavy work for you means that you are missing out on more profits and finding potential high level officers in pods. This way it balances how much you wish to use the exploration team, plus it costs you credits to keep the exploring going, plus it will take a certain amount of time for the team to complete its task. So there is a balance in order to not abuse it, but it does make the activity feel more passive as well.
