Might want to check out what snopes has to say about that before you stay up late waiting.
Mars made its closest path on aug 27th 2003! And it was nowhere near as large as what the email boasts that circulates once in a while. it was visible with the naked eye, but it was nowhere near the size of the moon.
In all actuality, mars gets pretty close to earth every 2 years. and super close about every 15-17 years. Within a few million miles of the 2003 event. It will be a while though before its closer than 2003, I think the 2287 date is actually correct there.
