Pass the Sputnik Boulder like you are going up to the Lower Satellites and the Third Flatiron. After an S-turn in the trail, you will come to a fork. At the fork in the trail, instead of going left up the trail next to the huge wall known as The Wave, turn right like you are going to the base of The Second Flatiron.
On your left next to the trail after about 20 feet is a short, north-facing and obvious hand traverse (Mission Control) that arches up and left to the corner and up. Around the corner to the left, the boulder is dramatically undercut with about 8 feet of face climbing to the top.
Spaceman Spiff begins from a sit start with both hands on a huge shelf under the undercut. Use miniscule crimps, shallow pockets and a heel-hook/scum to pull out onto the face, then get your feet underneath you and go to the top.
