Ice Cube had a good day on Space Mountain ... where he busted out his "F**k tha Police" face just in time for the release of "Straight Outta Compton." 

Cube and fam hit up Disneyland last weekend, and instead of his "Are We There Yet?" grin -- he flashed the hardest mug in the entire galaxy.

Sorry, Mickey ... you're not gonna catch O'Shea Jackson Sr. slipping.

In the shuttle, gettin' ready for flight ... lookin' in my mirror, not a Martian in sight.
