Pass the Sputnik Boulder like you are going up to the main area for the Lower Satellites and the Third Flatiron. Do a big S-turn past some other boulders and you will come to a fork in the trail. Go left towards the main Satellites area. Pass The Wave on your left and the Stardust Boulder (with the classic Aerogel) on your right.
Just after the Stardust Boulder, turn right into the talus toward what looks like (and is) an immense boulder. Your Mother ascends the middle of the North face of the Mothership from a sds down in a slot. Using a good hand hold, use some small intermediates to get to a good slot. Grab the one edge on the slopey topout, and do a long reach move to another good edge. Use that to pull over and ascend the slab for 30 or so feet until you can downclimb the other side. Cool moves but too short.
a pad or two are nice
