Still, NASA should've just waited to launch their rovers until the 26th if they knew this thing was going to come so close. Seriously. Patience is a virtue, guys.
Anyhow, the purpose is of this post is not merely to inform you about the up and coming celestial event, but also as an opportunity to engage in rampant silliness. Clearly, this is the "opportune moment" for any and all martians to invade. So! I have compiled a list of alien types from different movies and television shows, and I figure we can do an Alien: Survivor to determine which species of martian is going to rain doom on us from the skies! Standard operating procedure, vote for the alien you consider to be the weakest link. Let's kick 'it off, shall we?
Here's our competition, who is the least fit to compete?
Virtually indestructable, black, acid dripping aliens from the Alien series.
The War of the Worlds aliens
The Vogons from Hitchhiker's Guide to the Galaxy
"Bugs" aka Giant Cockroaches that eat the likes of Tommy Lee Jones
The orange, glowing, sea-blob aliens a la Invasion (see also: Invasion of the Body Snatchers)
Marvin the Martian
Mangalores, the Fifth Element
The Goa'uld c/o Stargate SG-1.
Nymphomaniacal aliens from the Species series (i.e. Sil)
Pimp if you like! Let the annihilation begin!
ETA: I have no idea how I managed to spell "invader" incorrectly. Sorry about that.
