In what's called a "planetary conjunction," Venus and the Red Planet will be easily visible in the same field of view despite being tens of millions of miles apart in outer space.

The crescent moon will approach Venus and Mars above the western horizon about 45 minutes after sunset. Both planets are key targets for the next generation of space exploration.
