NASA is putting pause on sending commands to its Mars exploration instruments from November 11 through November 25 as it waits out the Mars solar conjunction. With the sun in the way, any commands sent to Mars could suffer interference capable of harming the robotic explorers.

Twilight may work then. They just need to thread the needle using beam-forming to ensure the comms make it past those pesky celestial bodies.
