Will there be any meteorites detectable on Mars when the Comet goes by?

I know you probably are not excited when someone mentions the face on Mars or things like that which people see, and then ask you if you believe its alien. Well I have observed the Moon's "x" and "v" that appears on the terminator. And recently discovered a Large "X" on the moon.I was wondering. How does one (me as an Amateur Astronomer) when I find something new like this "x" on the moon or a feature on Mars, How do I report it and to who?
