Aeronaut is naut really its own route, but is a fantastic continuation to Aerospace (hence the 3 stars).
From the bolted anchor atop Aerospace, head left across some loose, rotten rock to a roof. A few stoppers can be had at this roof, and there is a bolt just over it. Pull the roof to a large, positive shelf, and then do a committing mantle onto this shelf. From here, slab climb and work the arete past a few more bulges (and bolts) to the top.
Shameless beta follows:
Spend a long time like I did trying to figure out how the roof could possibly be 11b (the big hold looks so close from the belay but it's agonizingly out of reach), or, instead, work your left foot into an unlikely jam in a slot under the roof, reach up with your left hand to an intermediate crimp a foot below the big hold, and go from there.
