I'm kinda meh about these flowers, but I find the unopened bud in the top left corner kind of interesting.
Space Race is a hybrid of Onc. Sphacetante and Onc. Pupukea Sunset. The former tongue-twisty name is a clumsy mashup of its parents' names, Oncidium sphacelatum and Oncidium Debutante (I would have recommended "Debutatum," if anybody had asked me, but of course nobody ever does.), and I didn't care to track down the ancestry of Debutante, so that is left as an exercise for the reader. Pupukea Sunset is a hybrid of the two species Oncidium fuscatum and Oncidium cheirophorum.
Space Race most strongly resembles O. sphacelatum, which is also yellow with some brown or red-brown spots. I much prefer the looks of O. fuscatum (brown, with a large pink and white labellum) or O. cheirophorum (solid bright yellow), but that's just me.
