Well according to astronomers mars is going to be closest to earth in 75000 years and on The 27th of August and you well be able to see it with the naked eye. Its really cool I looked out side last night and the moon was red and just awhile ago I was outside skateboarding and the sun was bright red when it was going down. If you look outside at night you might see the moon red but it stays red only for a short awhile
