Nothing to do with Mars but some here seem interested in the night sky.
This is one of the better on line Planitariums.

Pretty simple just put in your lattitude and longatude in locations and set a direction and you have the night sky on your computer as you would if you looked out in the sky in the direction that you have set.
For those you are interested in Near Earth Objects (NEO's) this will give you the orbit date and the AU distance.
