Space Opera and Planetary Events

I am writing a space opera and I have planned a space battle and then arrival on a planet. I want the main character to get involved with the planetery events, but I feel that will take page time away from fleet battles. So I am thinking of focusing on planet events and have events in space slowly creep into the main characters sphere that prompts them to go back to the stars and handle them, possibly effecting his work on planet.

Do you think this switching will annoy readers?
