The night sky is going to be putting on a rare and impressive show tonight.
The Earth, Mars, and the sun will be in an almost straight line.
This means Mars will rise in the east near sunset and be visible all night long, moving nearly overhead through the night.
NASA astronomers say it won't be hard to see.
It will be ten times brighter than the brightest stars in the sky, showing up as a bright burnt orange color.
The National Weather Service says no big storms are in the forecast, so Mars should be visible in most areas of the U.S.
